I am currently working with a db that utilizes a subtype / supertype structure. I am wondering the best approach to handling INSERTs. Do I keep the population of multiple tables in the SQL itself, or with PHP, or even a combo of the two?
I am using MySQL / PHP (w/ Yii Framework)
Don't know whats up with a down vote. Didn't realize the importance of any tables as this is a general approach question. But here is an example. If a Party is created how do Business and or User get populated with that PartyId? SQL/PHP/Both?

I've run into a bug with my app that I traced down to inconsistent text rendering between Chrome and Firefox 4.
Chrome tells me that a certain string of text is 215px wide whereas Firefox 4 tells me its 218px wide:
A bit of searching [indicates](http://www.google.com/search?q=inconstent&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a#sclient=psy&hl=en&client=firefox-a&rls=org.mozilla:en-US%3Aofficial&source=hp&q=firefox+4+text+rendering&aq=f&aqi=&aql=&oq=&pbx=1&bav=on.2,or.r_gc.r_pw.&fp=942a00f1e606939&biw=1920&bih=977) that the issue is with Firefox 4, not Chrome.
The following code renders the text on the canvas element as well as via HTML and outputs the width:
```
<html>
<head>
<title>Firefox 4 Text Rendering Bug</title>
<script type="text/javascript">
function draw(){
var canvas = document.getElementById('tutorial');
if (canvas.getContext){
var ctx = canvas.getContext('2d');
ctx.font = "bold 16pt Helvetica"
ctx.fillText("MORE INFORMATION", 0, 16)
alert(ctx.measureText("MORE INFORMATION").width);
}
}
</script>
<style type="text/css">
canvas { border: 1px solid black; }
h2 {font-size: 16pt; font-family: Helvetica; font-weight: bold }
</style>
</head>
<body onload="draw();">
<canvas id="tutorial" width="220" height="20"></canvas>
<h2>MORE INFORMATION</h2>
</body>
</html>
```
Is there a way to render text consistently between the browsers?

Using [ColorZilla](http://www.colorzilla.com/) I found an interesting feature. If I pick a color from firefox (bars,tabs or anything else of the browser) and then go to:
> ColorZilla > Inspect Last Element > In
Firebug
Then I can see the markup,css,js that firefox uses in the firebug panel just like a website.
Is there any solution to view this code without use Colorzilla?

While going through SQL profiler, I noticed the following query generated by EF4.
```
exec sp_executesql N'declare @p int
update [dbo].[User]
set @p = 0
where (([UserID] = @0) and ([RowVersion] = @1))
select [RowVersion]
from [dbo].[User]
where @@ROWCOUNT > 0 and [UserID] = @0',N'@0 int,@1 binary(8)',@0=1,@1=0x000000000042DDCD
```
I am not sure why EF4 generates this while I am actually not updating any columns of the User table in that UnitOfWork. Running this query updates the which leads to OptimisticConcurrencyException in the next UnitOfWork.
A quick googling led me to this [link](http://social.msdn.microsoft.com/Forums/en-US/adodotnetentityframework/thread/e2444f09-d6e1-4fdc-84d3-aaa28dc98fd8/), which confirms that others have also run into this scenario without finding a solution yet.
Would greatly appreciate any pointers.
A sample code to replicate the issue.
User and Session tables have a relationship. Also, in EF4 I have set the property of RowVersion columns of both entities to .
Below is a sample method to replicate the scenario.
```
private static void UpdateSession()
{
using (var context = new TestEntities())
{
context.ContextOptions.ProxyCreationEnabled = false;
var session = context.Users.Include("Sessions").First().Sessions.First();
session.LastActivityTime = DateTime.Now;
context.ApplyCurrentValues("Sessions", session);
context.SaveChanges();
}
}
```
I see from Sql profiler the following queries being genrated by EF4.
```
exec sp_executesql N'update [dbo].[Session]
set [LastActivityTime] = @0
where (([SessionID] = @1) and ([RowVersion] = @2))
select [RowVersion]
from [dbo].[Session]
where @@ROWCOUNT > 0 and [SessionID] = @1',N'@0 datetime2(7),@1 int,@2 binary(8)',@0='2011-06-20 09:43:30.6919628',@1=1,@2=0x00000000000007D7
```
And the next query is weird.
```
exec sp_executesql N'declare @p int
update [dbo].[User]
set @p = 0
where (([UserID] = @0) and ([RowVersion] = @1))
select [RowVersion]
from [dbo].[User]

I'm trying to make a website with a header that repeats along the entire page width, with the website's name centered in the header, and a logo slightly offset from the website name. If the screen width is too small to display the entirety of the logo, I just want it to cut off the logo to the right, otherwise the entire logo will be displayed (i.e. the monitor/window is big enough. What I don't want is to float the image to the right. I want it to, more or less, be absolutely positioned near the title.
However, I can't figure out a way to do this. I can't use overflow-x or overflow-y (because of browser support) and the mark-up i currently have just widens the window with a scroll bar to accomodate the entire image (see screenshot).
Here is the screen shot

Here is the mark up and CSS:
```
<div id="header-wrap">
<div id="header">
<img src="title-card.png" />
<img id="this-chick-logo" src="this-chick-logo.png" />
</div>

margin: 0px;
}
#header-wrap
{

width: 100%;
height: 291px;
}
#header
{
margin: 0 auto;
width: 1000px;
text-align: center;
}

I have a custom UITextField with a UIImage as a background. Now when I type in a text into this UITextField and the cursor is blinking I get this:
I don't want to have a white image on the cursor blinking as it destroys the aesthetics.
I tried playing around with this and tried setting the background view to have the same color as the image, however the issue is that the UITextField shape is always a rectangle. How do I solve this?

I'm creating a graphical timeline out of an excel document and I need to have small tags of the name of the event next to the marker for that event. Some of these are easy and are right justified but others are left justified and I need to figure out their width so that I can properly offset them.
```
window.drawString("7/4-Fourth of July",horizontalIndex-Offset,verticalIndex);
```
Currently I'm averaging the pixel width using an average of both font sizes 10 and 32, but this doesn't really cut it. Can someone help me get the exact offset?

If I define a Scala class:
```
class X(i:Int) {
println (i)
}
```
How do I use this class in Java code?
[EDIT] Actually, my problem is slightly more complicated
I have an abstract class
```
abstract class X(i:Int) {
println (i)
def hello(s:String):Unit
}
```
I need to use this in Java code. Is it possible to do it easily?
[EDIT2] Consider the following code
```
object B {
case class C(i:Int)
}
abstract class X(i:Int) {
println (i)
def hello(a:B.C):Unit
}
```
In this case, the following java code gives an error in Netbeans IDE but builds fine:
```
public class Y extends X {
public void hello(B.C c) {
System.out.println("here");
}
public Y(int i) {
super(i);
}
}
```
The error I get is:
```
hello(B.C) in Y cannot override hello(B.C) in X; overridden method is static, final
```
Netbeans 6.8, Scala 2.8.
As of now I think the only solution is to ignore the NB errors.
Here is an image showing the exact error(s) I get:

By setting the lineHeightMultiple of a NSParagraphStyle that is used in a text view I'm getting drawing artifacts when selecting text. This is reproducible in TextEdit. More specifically:
1. Open TextEdit in rich text mode
2. Pick Courier 14 as the font
3. Set line height multiple to 1.4
4. Insert a bunch of text
5. Select a portion of text with the mouse until the top
6. Start decreasing the selection (moving the mouse down)
In some lines, the selection is not totally cleared, leaving a 1px horizontal artifact behind (see screnshot). This also occurs with different fonts, font sizes as lineHeightMultiple values (although not all).
Has anyone experience this or has any idea why this is happening?
Thanks,
Rúben

[custom UITextField with image as a background blinking cursor issue](https://stackoverflow.com/questions/6232434/custom-uitextfield-with-image-as-a-background-blinking-cursor-issue)
I have a UIImageView (the image has a pattern, gradient, and shadow in it). I have added a UITextField as a subview of this UIImageView and set the textField background to clear so that it's seen through, the code is:
```
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(10, 12, 359 , 36)];
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.textColor = [UIColor whiteColor];
textField.placeholder = @"USERNAME";
textField.backgroundColor = [UIColor clearColor];
textField.font = [UIFont systemFontOfSize:15];
textField.delegate = self;
[username_background addSubview:textField];
```
The issue is that when I start editing the UITextField, I got the following layout issues:
Before editing:
When editing:
I can fix this if I change the UIColor clearColor background to some other color, but apparently I find difficulties getting the appropriate color for the background. I did try doing:
```
[[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"bkg-username.png"]];
```
However, what I am getting is:

Right now, I have a layout that looks like one of the two images below, depending on the exact size of the screen. Bot that on one, the Play Game! button is on top, and on the other, the copyright text is on top.
 
What I'm trying to do is to put an image between the adview and the higher of the top text box/layout. Depending on different screen sizes, the entry that's on top can vary. I would like to not have this problem at all... I know how to put it below the imageview, but not put it above both items.
So far, I've tried a relativeLayout that encloses the bottom variables, and told the image to be above that, but below the AdView. Problem is, the top of the RelativeView goes clear to the top, despite it being set to wrap_content and none of the below values go that high.
I've also considered aligning either the top of the text to the top of the button, or visa versa, but I'm seeing a potentially ugly interface in my mind, one in which the top button might be bigger, or part of the copyright text obscured.
So, I'm looking for one of two solutions. A way to tell my image to be above 2 items, the button and the text, or some way to wrap the context such that I can just be above the wrapped value.
Here's the relevant XML code I've tested.
```

The problem that I am facing is that whenever I touch the white area(where the activity is present) it senses the which I just want for the areas in grey(highlighted in red colors). I just want the touch to be activated for the area outside the white activity area for hte complete screen.
Any help would be really appreciated.

### I'm using jQuery Isotope to fill in the spaces on a multi-width multi-height grid (equal proportions).
The grid is sorted using ui-sortable with a button to toggle back to Isotope after sorting. There are some sort orders that leave empty blocks. How can I use Isotope to fill in the spaces?
I've experimented with multiple Isotope layout methods.
### See http://jsfiddle.net/zdSYG/41/
```
$(document).ready(function() {
var $itemList = $('#sortable');
$itemList.isotope({
resizesContainer: false,
masonry: {
rowHeight: 250,
columnWidth: 325
}
});
$('#wp-admin-bar-edit').click(function() {
$itemList.isotope('destroy');
$itemList.sortable({
//Do Ajax Stuff with UI-Sort Order
});
});
});
//Toggle back to Isotope after jQuery UI-Sortable Ajax stuff
$(document).ready(function() {
$('#wp-admin-bar-sort').click(function() {
$('#sortable').isotope({
resizesContainer: false,
masonry: {
rowHeight: 250,
columnWidth: 325
}
});
});
});
```

I am currently trying to use `pHash.dll` on [http://phash.org](http://phash.org/)
Unfortunately it was written in C++, I'd have to use `DLLImport`
But the problem I am having is how to register `pHash.dll` (compiled thru VS2010/C++)
I've tried to register using `regsrv32` and have been fruitless giving an error message.
Now, How can i register `pHash` to show up in COM tab?

I want the two vertical borders in this mockup to be the same height (i.e., the height of the containing block):
As you can see, the left border looks good (because the left column is the tallest column), but the right border is too short (since the middle column is shorter than the left column)
I know I can do this by giving the containing block an explicit height and giving each child a height of 100%, but I'd prefer not to do this – instead I'd like to allow for different height "forum thread holders" without ugly scrollbars / overflow

There's a website I built a few years ago using sIFR. Nothing's really changed on it at all in terms of styling — just some content added/removed edited via XML.
The site owner emailed me today asking why suddenly some of the text (rendered in sIFR3) is breaking like this:
I could not reproduce this on of my browsers. It was happening to him in both FF and Safari (Mac). We are using the same browser versions on the same OS. He was on OS X 10.6.6 but upgraded to 10.6.7 while were trying to narrow down what would cause it. He still got the "incorrect" version. I downgraded my Flash plugins to the exact version he had on his computer, and I still had the "correct" version. He checked all the other computers at his office, and all rendered it correctly as well.
So in two environments where all of these things were identical:
- - -
What other possibilities could be causing the discrepancy?

I have a simple plane `Mesh` that is 100x100. Following the libgdx tutorials I've successfully mapped a texture over the mesh. However, it looks odd right from the start, and even stranger when I zoom out. What I'm aiming for is a simple grid pattern.
## Here's the plane zoomed in:
## Now zoomed out:
The texture itself is a small 64x64 square, outlined.
My `Grid` class looks like this (Grid extends gdx.graphics.Mesh):
```
private final int HALFWIDTH = 50, HALFLENGTH = 50;
private Texture texture;
public Grid() {
super( true, 4, 4,
new VertexAttribute(Usage.Position, 3, "a_position"),
new VertexAttribute(Usage.ColorPacked, 4, "a_color"),
new VertexAttribute(Usage.TextureCoordinates, 2, "a_texCoords")
);
setVertices(new float[] {
-HALFWIDTH, -HALFLENGTH, -2f, Color.toFloatBits(255, 0, 0, 255), -HALFWIDTH, HALFLENGTH,
HALFWIDTH, -HALFLENGTH, -2f, Color.toFloatBits(0, 255, 0, 255), HALFWIDTH, -HALFLENGTH,
-HALFWIDTH, HALFLENGTH, -2f, Color.toFloatBits(0, 0, 255, 255), -HALFWIDTH, HALFLENGTH,
HALFWIDTH, HALFLENGTH, -2f, Color.toFloatBits(0, 255, 255, 0), HALFWIDTH, HALFLENGTH
});
setIndices(new short[] { 0, 1, 2, 3 });
this.texture = new Texture( Gdx.files.internal("assets/grid.png") );
this.texture.setWrap( TextureWrap.Repeat, TextureWrap.Repeat );
this.texture.setFilter( TextureFilter.Linear, TextureFilter.Linear );
}
void draw() {
Gdx.graphics.getGL10().glEnable(GL10.GL_TEXTURE_2D);
this.texture.bind();
render(GL10.GL_TRIANGLE_STRIP, 0, 4);
}

I have the following situation:
1) 1 X PhotoTableViewController to display a list of photos (one photo per cell) like what Instagram does
2) A refresh button in the navbar of PhotoTableViewController to do a table reload (top right)
3) An option button in the navbar of PhotoTableViewController to select a list of options e.g. "Latest photos, most popular etc) (top left)
4) A "Load more" cell at the end of the list (limit to 20 photos) to append the next set of photos to the table view.
The photos are obtained from a server and comes in a form of a JSON file.
Query: I believe that all 3 buttons (point 2,3 and 4) essentially want to do the same thing, which is to refresh and reload the table. Also my understanding is that this is a common sort of practice in a few apps, so I would like some advise on the following
1) How do I implement this sort of 'Refresh' and 'Reload' method in the most effective way without repeating code.
2) After I click each button, the intention is to sort of have a 'Blank page' with a spinner and show only the reloaded table after processing is completed. I am thinking of popping the current tableview controller at point of button click and push a new controller back once processing is completed. Does this make sense? Or is there a better way of doing it?

I have found some nice dark themes for editing code in Eclipse (screenshot below), but they only apply to the code window itself. The package explorer and outline view are still white background. It would be great if there was some way to make everything dark, even the toolbar at the top. Is this possible?
Thanks,
Jonah

I am rendering a complex scene in WebGL (180 meshes) corresponding to a car model (Nissan GTX) . However when I move the camera around , it seems as if triangles were missing ,
These 'missing triangles' seem to jump randomly over the surface. Can this be a depth buffer problem or a normal calculation problem? I have no idea.
Nevertheless, if I zoom-in near the surface of the model, all triangles are there .
Does anyone have had this problem? any tips?!

I need to write a simple app for a [Symbol MC70 scanner](http://www.nationalbarcode.com/Symbol/Symbol-MC70-Specifications.htm)
My device is loaded with: Microsoft Windows Mobile 6.1 Premium
I have VS 2010 Premium on my desktop.
When installing the Window Mobile 6 SDK I get this error:
I read this article:
[Windows Mobile 6 Standard SDK Refresh install issue on Visual Studio 2010 Professional Beta 2](https://stackoverflow.com/questions/1779874/windows-mobile-6-standard-sdk-refresh-install-issue-on-visual-studio-2010-profess)
Using WinForms I can knock this app out in 3 hours. I'm hoping I don't burn 3 days fooling around with SDK's etc.
Would it be best to try and update the devise to Mobile 7 and use VS 2010?
Thanks so much for any help!!

I'm using XCode 4 and I just created a subclass of UIViewController, status bar enabled (grey), and dropped in a MKMapView. My UIView has x,y and w,h of
(0,20) / (320,460)
Then I click on my MKMapView and it has coordinates of:
(0,0) / (320, 460)
Is there a reason that IB doesn't resize itself so the MKMapView will take up the entire screen by making it (0,0)/(320, 480), or putting itself at (0,20)/(320,460)?
The picture below should identify my problem. Sorry if I am missing something super obvious. Thanks.

I am trying to center a spinner in the middle of the page using the code below.
```
self.aSpinner.center = self.view.center;
```
However when when I run the program, the spinner does not seem to be in the center
Is there any way to fix this?
EDIT:
I found the problem. It's not that the spinner is not in the center, but instead the subview has different bounds than its superview.
I am doing something like this in my code:
```
self.navcon = [[UINavigationController alloc]init];
self.photoViewTable = [[PhotoTableViewController alloc]init];
self.loadingPage = [[LoadingPageViewController alloc]init];
[self.photoViewTable.view addSubview:loadingPage.view];
[navcon pushViewController:photoViewTable animated:NO];
[self.window addSubview:navcon.view];
```
How can I set the size of `loadingPage` view to be equal to the parent view?

In the attached picture of a fragment layout from google's blog I have a listview in my code. My question here is to set the first two items(Henry IV and Henry V) with background colors RED and others remain as defaul backgroudn values. Is this possible?
Any help would be really appreciated.
Thanks,
Sana.
The code that I use to get the ListView is
```
Log.i(TAG, "Selected item position = "+getListView().getCount()+" Child count = "+getListView().getChildCount());
for (int i=0; i<getListView().getCount();i++) {
Log.i(TAG, "Item id = "+getListView().getItemIdAtPosition(i));
View v = getActivity().findViewById((int) getListView().getItemIdAtPosition(i));
View v1 = getListView().getChildAt(i);
Log.i(TAG, "Condition = "+(v == null)); //Here I get the display as true
Log.i(TAG, "Condition1 = "+(v1 == null)); //Here I get again a true, so basically both are none!
}
```

I followed a tutorial to make a Custom Control. What I basically did was make a new project, add a file `CategoryBar.cs` and a directory called `Themes` with a file `Themes\generic.xaml` (with Compile type set to 'resource'). Then I wrote a class `CategoryBar.cs`, filled up the `generic.xaml` with a ResourceDictionary. Let's call this project the 'UILib':
```
<?xml version="1.0" encoding="utf-8" ?>
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
xmlns:local="clr-namespace:ErnestUILib">
<Style TargetType="local:CategoryBar">
<Setter Property="Background" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:CategoryBar">
<Grid x:Name="GridView" Background="{TemplateBinding Background}" Margin="0,0,0,8">
<!-- The grid rowdefs, coldefs and whatever makes up the grid -->
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
```
And it all runs completely fine in a project where I add a reference to this library. I added the attribute `xmlns:EULib="clr-namespace:UILib;assembly=UILib"` to `<phone:PhoneApplicationPage .. />` and it's working fine. Now, I wanted to implement another control (as I want to have one separate and exactly one library for custom UI controls). So now my generic.xaml looks like:
```
<?xml version="1.0" encoding="utf-8" ?>
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
xmlns:local="clr-namespace:ErnestUILib">
<!-- THE NEW CUSTOM CONTROL -->
<Style TargetType="local:PaginationBar">
<Setter Property="Background" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:PaginationBar">
<Grid x:Name="GridView" Background="{TemplateBinding Background}" Margin="0,0,0,8">
<!-- The grid rowdefs, coldefs and whatever makes up the grid -->
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- THE PREVIOUS CUSTOM CONTROL -->
<Style TargetType="local:CategoryBar">
<Setter Property="Background" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:CategoryBar">
<Grid x:Name="GridView" Background="{TemplateBinding Background}" Margin="0,0,0,8">
<!-- The grid rowdefs, coldefs and whatever makes up the grid -->
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
```
Here, I've created a class `PaginationBar` in `PaginationBar.cs` and it's all setup, but when I try to use it in my application's xaml file, it shows a white-filled rectangle in the designer view with a cross at it's top left corner and it says that an exception was caused 'Control_TargetTypeMismatch'. After a few trickeries of mine, nothing still worked, but the Designer just doesn't load when I use `<UILib:PaginationBar .. />` and instead gives an error `System.Reflection.TargetInvocationException` (Exception has been thrown by the target of an invocation). When I run the project, it gives some XamlParseException error. This is the only exception I'm able to get some details out of, none of which I think are even remotely useful. Anyhow, this is what I get with the XamlParseException:
I have no clue how to proceed. Any help is greatly appreciated. Thanks in anticipation :)

Good Evening,
I'm building a website which will will look something like this:
So probably a widget-centred web-framework would be best...
Which C++ web-framework supports cookies (for user-login [session] storage+config storage) and SQL (MySQL or SQLite)?
My information about Wt was outdated, it looks like they now have full-support for cookies ([http://redmine.webtoolkit.eu/boards/1/topics/2111](http://redmine.webtoolkit.eu/boards/1/topics/2111))
CppCMS however has a vibrant community, and there product seems to scale better.
I will do the diplomatic thing, create a project using both frameworks.
It will be a cutdown version with only:
- - - -
Should be an interesting project... I wonder if any have done this in the past?!

I have an UINavigationBar, and I'm trying to add the user avatar to before the text, and I want 't so it's just before, and thought if I add it with IB, if the tabBar title is longer it would look ugly, so how could I add it on the front of the navBar? It would look like this of Osfoora:

### HTML:
```
<div class="imgcontainer">
<ul>
<li><img src="1.jpg" alt="" /></li>
<li><img src="2.jpg" alt="" /></li>
.....
</ul>
</div>
```
I'm coding a simple gallery page by creating unordered list and each list item of it contains an image.
```
ul li {
float: left;
}
```
I set the width of the container as "max-width" so I can make possible to fit the list items (images) to the browser width.. meaning that they will be re-arranged when the browser window re-sized.
```
.imgcontainer{
max-width: 750px;
}
```
Now the problem is those images or list items are not aligned to center, they are aligned to the left of .imgcontainer body (colored gray in the attached link below), leaving a space on the right when the window re-sized!
How can I center those images every time the window resized?
Here's the whole page/code you can preview it or edit it at JS Bin

I'm applying a blur effect to an image in WPF like so:
```
<Image ClipToBounds="True">
<Image.Effect>
<BlurEffect Radius="100" KernelType="Gaussian" RenderingBias="Performance" />
</Image.Effect>
</Image>
```
As you can see, the radius is large, because the image is large and I need it to be blurry. However, for a radius that large I'm getting a light frame around my image as seen in the attached image. How can I suppress this?
In case you're wondering: The result is the same not matter the `RenderingBias`. A border is also produced in quality-mode.

Is there a way to whiten out the background of the axis label so that when it crosses the axis line itself, the latter does not run through it?
For example, this script (the best I managed so far)
```
#!/usr/bin/python
import matplotlib.pyplot as plt
xx=[1,2,3]
yy=[2,3,4]
dy=[0.1,0.2,0.05]
fig=plt.figure()
ax=fig.add_subplot(111)
ax.errorbar(xx,yy,dy,fmt='ro-',ms=6,elinewidth=4)
ax.set_xlim([0.,3.4])
ax.set_ylim([0.,4.4])
ax.set_xlabel(r'$T/t$',fontsize=16)
ax.set_ylabel(r'$S(\mathbf{Q})L^{1+\eta}$',fontsize=16)
# position the axis labels
ax.xaxis.set_label_coords(1,0)
ax.yaxis.set_label_coords(0.1,0.93)
ax.yaxis.get_label().set_rotation('horizontal')
ax.yaxis.get_label().set_backgroundcolor('w')
#ax.yaxis.get_label().set_zorder(222) #doesn't do the trick
plt.show()
```
produces almost what I'm looking for, but still the y-axis runs over the label: .

I have a folder containing about 2500 PNG images, with no transparency. Every image is about 500 x 500 (some are 491 x 433, others 511 x 499 etc).
I want to programatically downsize every image to 10% of its original size, and to set the white background of every image as the transparent color.
To test the functionality of my application without resizing 2500 images every time, I used 15 images of billiard balls as a "test" folder.
Now my problem is with the following code, I get a resized and cropped PNG, whith a transparent background. The problem is that a white border on the left and top appears in every image viewer (Irfan View, Paint.Net and GIMP)
How can I avoid this border?
Here is the code I used for this:
```
void ResizeI(string[] Paths, string OutPut, Methods m, PointF Values, bool TwoCheck, bool Overwrite, float[] CropVals)
{
for (int i = 0; i < Paths.Length; i++)//Paths is the array of all images
{
string Path = Paths[i];//current image
Bitmap Oimg = (Bitmap)Bitmap.FromFile(Path);//original image
Bitmap img = new Bitmap((int)(Oimg.Width - CropVals[0] - CropVals[1]), (int)(Oimg.Height - CropVals[2] - CropVals[3]));//cropped image
Graphics ggg = Graphics.FromImage(img);
ggg.DrawImage(Oimg, new RectangleF(((float)-CropVals[0]), ((float)-CropVals[2]), Oimg.Width - CropVals[1], Oimg.Height - CropVals[3]));
ggg.Flush(System.Drawing.Drawing2D.FlushIntention.Flush);
ggg.Dispose();
PointF scalefactor = GetScaleFactor(img, Values, TwoCheck);//the scale factor equals 0.1 for 10%
Bitmap newimg = new Bitmap((int)(Math.Ceiling(((float)img.Width) * scalefactor.X)), (int)(Math.Ceiling(((float)img.Height) * scalefactor.Y)));
System.Drawing.Imaging.ImageFormat curform = img.RawFormat;
string OutPath = System.IO.Path.Combine(OutPut, System.IO.Path.GetFileName(Path));
OutPath = CheckPath(OutPath, Overwrite);//Delete if exsits
Graphics g = Graphics.FromImage(newimg);
g.InterpolationMode = GetModeFromMethod(m);//Bicubic interpolation
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
g.ScaleTransform(scalefactor.X, scalefactor.Y);
g.DrawImage(img, new Rectangle(0, 0, (int)Math.Ceiling(((float)newimg.Width) / scalefactor.X) + 1, (int)Math.Ceiling(((float)newimg.Height) / scalefactor.Y) + 1));
//g.Flush(System.Drawing.Drawing2D.FlushIntention.Flush);
newimg.MakeTransparent(Color.White);
newimg.Save(OutPath, curform);
g.Dispose();
img.Dispose();
}
}
```
And here is a example of the white border I mentioned. Download the image or drag it around and put a black background under it to see the border:
-- EDIT --
I managed to write this function instead of `newimg.MakeTransparent(...)`:
```
void SetTransparent(ref Bitmap b)
{
for (int i = 0; i < b.Width; i++)
{
for (int ii = 0; ii < b.Height; ii++)
{
Color cc = b.GetPixel(i, ii);
int tog = cc.R + cc.G + cc.B;
float durch = 255f - (((float)tog) / 3f);
b.SetPixel(i, ii, Color.FromArgb((int)durch, cc.R, cc.G, cc.B));
}
}
}
```
the problem is that my billiard ball now look like this:

I want to describe an issue I have been having with `Plot` using `With` to keep defined parameters 'local'. I am not necessarily asking for a fix: the problem I have is one of understanding.
Sometimes I use a construction such as the following to obtain a Plot:
```
plot1 = With[{vmax = 10, km = 10},
Plot[Evaluate@((vmax x)/(km + x)), {x, 0, 100},
AxesOrigin -> {0, 0}]]
```
I like this method, and it is reasonably clear even to non- users exactly what is going on.
When the equations to be plotted become more complex, I like to define them external to the plot (using SetDelayed). For example:
```
f[x_] := (vmax x)/(km + x)
```
However, the following
```
plot2 = With[{vmax = 10, km = 10},
Plot[Evaluate@f[x], {x, 0, 100}, AxesOrigin -> {0, 0}]]
```
I have always naively thought that it should. However, based on the Help statement that
> Plot treats the variable x as local,
effectively using Block
I have used various workarounds, mostly something like the following
```
plot3 = Plot[With[{vmax = 10, km = 10}, Evaluate@f[x]], {x, 0, 100},
AxesOrigin -> {0, 0}]
```
This one seems very awkward, and usually requires further explanation even to users.
However, recently I found out by chance that substituting `Block` for `With` in Method 2 works exactly as expected.
I can, for example, do something like the following (which to me seems a very versatile approach):
```
plot4 = Block[{vmax = {10, 10, 10}, km = { 10, 100, 1000}},
Plot[Evaluate@f[x], {x, 0, 100}, AxesOrigin -> {0, 0},
PlotStyle -> {Red, Green, Blue}]]
```
giving
My questiions are as follows. What is the explanation for the difference in behaviour with `With` in Method 1 and 2? Should I have expected Method 2 not to work? Furthermore, what is the explanation for the difference in behaviour with `Block` and `With` in Method 2? Should I have been able to predict that `Block` would work?
Funnily enough many workarounds have been suggested to me by those more experienced than I, but nobody suggested using `Block`.
Finally, I need to keep `vmax` and `km` local.(They have been defined algebraically elsewhere)

I use eclipse as my IDE for python. Recently I encountered a strange problem.
A file contains an import from external libraries (such as wx, matplotlib etc.) if I put it inside the src directory, it will run as expected, but in the editor, I get error marks all over the places where I use the imported libraries. The errors say things like "Undefined variable from import".
If I put it in top level of the project, the error marks disappear.
I have added a screenshot of the configuration. I have a feeling that the source of the problem is there, but do not know what to do.

HI,
I am assigned a task to develop module for an already existing web application or to look for some third party plugin.
The web application is developed using ASP.net and C# under .Net Framework 4.0. So if i develop by myself or i go for some 3rd party plugin then in both cases, my solutions need to work with above website specifications.
# What I am Assigned:
I need to draw a figure(or map) which illustrates that how companies registered on our website are connected with each other and then their sub companies, i am sorry i don't know how to explain it exactly :(, but following image would give a better idea what i want to achieve. I never do such task before, and only need guidance.

I've been having an issue which is extremely odd to me. The graphic I'm using is sometimes centered, for reasons I can't understand, but only on certain displays. The top graphic is the bad example, the bottom one is the one I'd like to have. It seems to not be Android version dependent, both the good and bad were replicated on Android 1.6, and the bad was replicated on 2.1. It seems to only be size dependent...
relevant XML code:
```

```
As you can see, I've clearly set the gravity of the image to left, told it to align with Parent left, yet for some unknown reason it wants to align center.

Why is my graphic sometimes centering using a relative layout?

Chrome renders #FF3A00 as #FF0000 for some reason. I included a screenshot from [jsfiddle](http://jsfiddle.net/L9xy4/) to illustrate the point. The colour that the Color Meter reports (and what I see) differs from what CSS says.
This happens to other colours too. For example, #FFAF00 is rendered as #FFA400 according to the Color Meter.
However, the colours are rendered without problems on Safari and Firefox. I'm on a Mac using Chrome 11, Safari 5 and Firefox 5.
I'm sure there's a logical explanation. Any ideas?
Update: I'm attaching a screenshot of Chrome next to Safari showing the very same page. I checked this image in Photoshop: the colours are #F00 in Chrome and #FF3A00 in Safari.

I have a menu:
```
<div class="headerMenu">
<ul>
<li><a href="#">Home <span>Home Page<span></a></li>
<li><a href="#">About <span>About My Website<span></a></li>
<li><a href="#">Contact <span>Get in touch<span></a></a></li>
</ul>
</div>
```
My current CSS is as follow:
```
.headerMenu{
width: 100%;
}
.headerMenu ul{
margin: 0;
padding: 0;
float: left;
}
.headerMenu ul li{
display: inline;
}
.headerMenu ul li a{
float: left;
color: white;
padding-top:25px;
padding-left:50px;
font-size:24pt;
}
.headerMenu ul li a:visited{
color: white;
}
.headerMenu ul li a:hover, .menu ul li .current{
color: #fff;
background: url(../../Content/Images/menu-selector.png) repeat-x; /* 25x10 arrow/*
}
```
And now for the question:
1. How can i get the content in the span tag to be below the Main text.
2. When i hover over the anchor, How do i add the hover image as shown in screen shot
The Mockup i created in Photoshop looks like this:
I know this would be easily achievable by making use of images, but my solution requires that menu to be created dynamically.

I have a big form.
This form contains some inputs that can be duplicated by the user.
So they can choose for example how many Claimants have worked on a song and enter some fields for EACH claimant, with a limit of 10 Claimants.
The form will look like this (I will show only 3 now)
```
echo "<form action=\"\" id=\"submForm\" name=\"submForm\" method=\"get\">";
//1 CLAIMANT
echo "<p><span class=\"labelInput\">".(_t('_cR_name_mandatory'))." </span><input id=\"nameClaimant\" name=\"nameClaimant[]\" value=\"\" type=\"text\" class=\"required commonInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_DOB_mandatory'))." </span><input id=\"DOBClaimant\" name=\"DOBClaimant[]\" value=\"\" type=\"text\" class=\"required littleInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_company'))." </span><input id=\"companyClaimant\" name=\"companyClaimant[]\" value=\"\" type=\"text\" class=\"commonInput\"></p>";
//2 CLAIMANT
echo "<p><span class=\"labelInput\">".(_t('_cR_name_mandatory'))." </span><input id=\"nameClaimant\" name=\"nameClaimant[]\" value=\"\" type=\"text\" class=\"required commonInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_DOB_mandatory'))." </span><input id=\"DOBClaimant\" name=\"DOBClaimant[]\" value=\"\" type=\"text\" class=\"required littleInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_company'))." </span><input id=\"companyClaimant\" name=\"companyClaimant[]\" value=\"\" type=\"text\" class=\"commonInput\"></p>";
//3 CLAIMANT
echo "<p><span class=\"labelInput\">".(_t('_cR_name_mandatory'))." </span><input id=\"nameClaimant\" name=\"nameClaimant[]\" value=\"\" type=\"text\" class=\"required commonInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_DOB_mandatory'))." </span><input id=\"DOBClaimant\" name=\"DOBClaimant[]\" value=\"\" type=\"text\" class=\"required littleInput\"></p>";
echo "<p><span class=\"labelInput\">".(_t('_cR_company'))." </span><input id=\"companyClaimant\" name=\"companyClaimant[]\" value=\"\" type=\"text\" class=\"commonInput\"></p>";
echo "<input type=\"submit\" class=\"submBttnClass\" id=\"buttSubm\" name=\"buttSubm\" value=\"".(_t('_cR_submit_button'))."\">";
echo "</form>";
```
When the user submits the form I use a jQuery serialize function (I am on jQuery 1.3.2)
```
echo "<script type=\"text/javascript\">
$(document).ready(function() {
$('#submForm').validate({
submitHandler: function(form) {
var serialized = $('#submForm').serialize()
$.get('".$site['url']."modules/yobilab/copyright/classes/DO_submission.php', serialized);
//alert($('#submForm').serialize());
window.setTimeout('location.reload()', 8000);
return false;
form.submit();
}
})
```
The problem is that the file that processes the Insert in the Database uses a foreach(I will show you my entire foreach with all the inputs that are passed with the serialize function:
```
if(!empty($_GET['nameClaimant'])){
$nameClaimant = $_GET['nameClaimant'];
$DOBClaimant = $_GET['DOBClaimant'];
$companyClaimant = mysql_real_escape_string($_GET['companyClaimant']);
$emailClaimant = $_GET['emailClaimant'];
$mainPhoneClaimant = $_GET['mainPhoneClaimant'];
$alternatePhoneClaimant = $_GET['alternatePhoneClaimant'];
$mobilePhoneClaimant = $_GET['mobilePhoneClaimant'];
$percentageClaimant = mysql_real_escape_string($_GET['percentageClaimant']);
$addressClaimant = mysql_real_escape_string($_GET['addressClaimant']);
$ZIPClaimant = $_GET['ZIPClaimant'];
$countryClaimant = $_GET['countryClaimant'];
foreach ($nameClaimant as $valueClaimant) {
$insClaim = "INSERT INTO cR_Claimants SET memberID ='".$memberID."', ParentSubmission='".$refNumb."', Name ='".mysql_real_escape_string($valueClaimant)."', DOB='".$DOBClaimant."', Company='".$companyClaimant."', Email='".$emailClaimant."', Address='".$addressClaimant."', ZIPcode ='".$ZIPClaimant."', Country='".$countryClaimant."', MainPhone='".$mainPhoneClaimant."', OtherPhone='".$alternatePhoneClaimant."', MobilePhone='".$mobilePhoneClaimant."', OwnershipPercentage='".$percentageClaimant."'";
$resultinsClaim=mysql_query($insClaim) or die("Error insert Claimants: ".mysql_error());
}
}
```
The foreach inserts in the database wrong stuff. It shows `Array` instead of the right value.
I would like to insert the info in the database consequentially with my foreach.
So for Claimant1 will insert its relative info
for Claimant2 will insert its relative info and so on.
It is not working. What am I doing wrong?
I know it is a little boring, but please help me! Lets play with it. You are All great
Thank you
I have attached what is doing in the database to let you see
You will see that is also creating empty strings in the database.
Why is that taking also empty values?
Please help me.

I'm really need your help, I'm desperate.
I'm trying to build an OCR application and I'm facing some problems that I can't solve alone.
for now I'm cutting the plate form the image and doing some filtering to reduce the noise.
for example, this is the plate after cutting it from the image and after filtering:
now because that the plate is in angle and because that there is still noise (like above the numbers 9 and 3), the identification process(using corr2) is giving me the wrong numbers.
eg:
as you see the only problem is in the numbers 9 and 3(at the left side) where the noise is disturbing.
I thought to stretch the image so that each number will fit all the square (without the black lines at the top), but I can't find any method to do this that it will work for every image.
this is the results from the corr2 function, I marked in red the results of the numbers 9 and 3. 
please give me an idea or working solution...
any help will be greatly appreciated.

I am working on drawing custom buttons/textfields with `NSDrawNinePartImage`. I slice up an image into nine parts in code and draw it into a rect with `NSDrawNinePartImage`.
Unfortunately I am getting some gaps in the drawing pattern. I thought it had something to do with my slicing code, but I saved them out as images from where I slice them, and they all look good (I even put them together and they looked good). Some of the cases where I use it to work just fine though despite some using the same images.
I am pretty confident that it comes down to the actual drawing.
Do you know of any `NSGraphicsContext` or other settings that would affect it or something else that may be causing this?

I got most of my lighting working the way I want, but I seem to be completely missing any ambient lighting. That is, the away-from-the-sun sides of things are completely black (I was hoping for 50% ambient), whereas the toward-the-sun sides seem lit as I'd expect.
Here's my lighting setup code (edited from original, see note below):
```
- (void) setupLighting
{
const float amb = 2.0;
const float LightAmbient[][4] = { { amb, amb, amb, 1.0f },
{ amb, amb, amb, 1.0f }
};
const float LightDiffuse[] [4] = { { 1.0f, 1.0f, 1.0f, 1.0f },
{ 1.0f, 1.0f, 1.0f, 1.0f }
};
const float LightPosition[][4] = { { 1.0f, 4.0f, 2.0f, 0.0f },
{ 0.0f, 10.0f, 0.0f, 1.0f }
};
glLightfv(GL_LIGHT0, GL_AMBIENT, LightAmbient[0]);
glLightfv(GL_LIGHT0, GL_DIFFUSE, LightDiffuse[0]);
glLightfv(GL_LIGHT0, GL_POSITION, LightPosition[0]);
glLightfv(GL_LIGHT1, GL_AMBIENT, LightAmbient[1]);
// etc., snip -- no LIGHT1 for this round
glColorMaterial (GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE);
glEnable(GL_COLOR);
//glEnable(GL_COLOR_MATERIAL);
glEnable(GL_LIGHT0);
//glEnable(GL_LIGHT1);
glEnable(GL_LIGHTING);
}
```
(NOTE: LIGHT1 commented out for now -- I'm just trying to get LIGHT0 to do what I want.)
Not sure if it matters, but I'm drawing unit-aligned, texture-mapped unit cubes (a la MineCraft) using glDrawArrays(). All my normals seem correct; if I leave lighting off, everything draws correctly (just flat-lit.)
Any hints?
Thanks!
(Added screenshot.)
Per comments, I bumped ambient values up to 2.0, and now it looks like what I'd expect for about 50% ambient. That seems whacky -- I thought lighting values were pinned at [0, 1]...? What fundamental concept about ambient light am I not grokking?

Why doesn't my open gl ambient lighting work?

I'm programming a preferences panel with a UITableView which looks like this:
The first section consists in simple rows and the second section in rows with a UISwitch as a subview.
When I change to landscape and start scrolling, the tableview behaves in a strange way:
This is my code:
```
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell
if (indexPath.section == 0) {
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
if (indexPath.row == 0) {
cell.textLabel.text = @"Help";
}else if (indexPath.row == 1){
cell.textLabel.text = @"About us";
}
else if(indexPath.row == 2){
cell.textLabel.text = @"Send to a friend";
}
}else if(indexPath.section == 1){
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if (indexPath.row == 0) {
cell.textLabel.adjustsFontSizeToFitWidth = NO;
cell.textLabel.text = @"Show favs at launch";
[cell addSubview:favoritesSwitch];
}else if (indexPath.row == 1){
cell.textLabel.text = @"Open with Safari";
[cell addSubview:browserSwitch];
}
else if(indexPath.row == 2){
cell.textLabel.text = @"Remember query";
[cell addSubview:lastQuerySwitch];
}
else if(indexPath.row == 3){
cell.textLabel.text = @"Automatic keyboard";
[cell addSubview:keyboardSwitch];
}
}
return cell;
}
```
Thank you in advance :)

I'm working on an application where I list the installed applications with the package manager. I can get the package name of the item clicked, but I'd like to then launch the details screen based on the package. So for instance if Dolphin Browser were selected in the list, you would then see the following image. How can I do this?

```
final int apiLevel = Build.VERSION.SDK_INT;
Intent intent = new Intent();
if (apiLevel >= 9) {

//Toast.makeText(SDMove.this, "Gingerbread Not Currently Supported", Toast.LENGTH_LONG).show();
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS,
Uri.parse("package:" + pli.pkg.packageName)));
} else {
final String appPkgName = (apiLevel == 8 ? "pkg" : "com.android.settings.ApplicationPkgName");
intent.setAction(Intent.ACTION_VIEW);
intent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails");
intent.putExtra(appPkgName, pli.pkg.packageName);
startActivity(intent);
}

How would I go about implementing a shadow like the one you see under the title bar? I know this can be done (see for example the app "Andlytics", where this effect shows on the bottom as well).
My best guess is that it's a banner image used as the background for the layout. But maybe there is a better way?

I have the following Model design.
Template contains a list of Categories.
Categories contains a List of Items.
Thus there is 3 layer hierarchy. Because the UI design requires that all 3 levels be created on 1 page, I have had to write some of my own code to get this working. It looks as follows:
I can get it to submit back to the Create Action Method and the FormCollection looks as follows.
The problem I am having is that the UpdateModel works for the Template and Category level but the Items are not populated for the Categories. The Html looks as follows. As you can see, I have used the Category[guid_value].Items[guid_value] syntax for id. Shouldn't it figure out the binding automagically based on that?

Hi I'm new to android world.Iam working on an application that supports multiple screen sizes i did as explained here [http://developer.android.com/guide/practices/screens_support.html#screen-independence](http://developer.android.com/guide/practices/screens_support.html#screen-independence) . I didn't create different xmls for each screen size. But when I tested it on android 3 emulator it appears in small part of the screen.
So I think that the size specified for my application on the emulator is small so my widgets are not filling the whole screen as I want. Can I control that size of my application on the emulator?

I'm using `UIActionSheet` in a landscape mode application in `iPad`. Some of my button's texts don't fit the width and they're cropped from the end. In `iPhone` this is handled and my action sheet buttons fit into the frame even if they are long. I didn't understand why this is different in iPad. Do you guys have any ideas about how I can accomplish something as `adjustsFontSizeToFitWidth` method does to `UILabel`s?
Here's how I create and display my action sheet:
```
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
for (NSString *bank in self.getBanksResponse.banks) {
[actionSheet addButtonWithTitle:bank];
}
[actionSheet showFromRect:self.bankButton.frame inView:self.view animated:YES];
[actionSheet release];
```
Here's the screenshot of my action sheet:

The above image represents an article's page views over time. I'm looking for a decent, not to complex either physics or statistical calculation that would be able to give me (based on the history of the page views) what the current trending of the page views is for the past n days (which is represented by the blue box).
So basically, in the past 5 days is this link trending unusually higher than it usually does and if so by what degree/magnitude?
Ideally the accepted answer would provide an algorithm class that applies to this problem as well as some example of that using the data provided from this chart above.
thanks!

I want to convert a numeric value to a string, displaying culture-specific digits. For example, the Dari language used in Afghanistan (culture name "prs-AF") uses [Eastern-Arabic numerals](http://en.wikipedia.org/wiki/Eastern_Arabic_numerals) instead of the [Arabic numerals](http://en.wikipedia.org/wiki/Arabic_numerals) used in most Western cultures (`0,1,2,3,4,5,6,7,8,9`).
When examining the CultureInfo class built into the Framework, it lists the correct native digits (screenshot taken from output in LinqPad):
```
CultureInfo.CreateSpecificCulture("prs-AF").NumberFormat.NativeDigits
```
However, when trying to convert a number to a string to display in that culture, I am not getting the native digits:
```
var number = 123.5;
var culture = CultureInfo.CreateSpecificCulture("prs-AF");
Thread.CurrentThread.CurrentUICulture = culture;
Thread.CurrentThread.CurrentCulture = culture;
var text = number.ToString(culture);
Console.WriteLine(text);
```
Can anyone tell me how to display the native digits?

It's used by Google to sotre data about visitors of this link or when a user copy the link he'll get just the right URL .
The same thing with Facebook for external links ( l.php )
This option help user to see the whole address.
I like to use it in my website so how can I do ??

Apparently, the [EASEUS Partition Master](http://www.partition-tool.com/personal.htm) program can display the Windows GUI starts (i.e., it runs at the same time CheckDisk runs at boot).
What I :
1. This might require not-very-well-documented functions. That's fine with me.
2. I already know how to compile native NT executables, so feel free to omit that from responses.
Questions:
1. How can you display graphics before everything has started up? (i.e. What functions/libraries do you use?)
2. How does it display formatted and aligned text on the screen? I know NtDisplayString is capable of writing text, but it can't draw things in a formatted manner, as you can see below. What function(s) do you use to replicate the behavior below?

My kids have this fun game called [Spot It!](http://www.blueorangegames.com/spotit-tg.php) The game constraints (as best I can describe) are:
- - - -
The principle of the game is: flip over 2 cards and whoever first picks the matching picture gets a point.
Here's a picture for clarification:
(Example: you can see from the bottom 2 cards above that the matching picture is the green dinosaur. Between the bottom-right and middle-right picture, it's a clown's head.)
I'm trying to understand the following:
1. What are the minimum number of different pictures required to meet these criteria and how would you determine this?
2. Using pseudocode (or Ruby), how would you generate 55 game cards from an array of N pictures (where N is the minimum number from question 1)?
Pictures do occur more than twice per deck (contrary to what some have surmised). See this picture of 3 cards, each with a lightning bolt:

My index resource takes up half my sites load time. Google got it down to just about 30-50 ms, how would I go about achieving this?
Also, how can I parallelize the downloading of my images. They all wait for the previous one to load before starting to load, any way to fix this?
Thanks!

I'm just starting to get more into CSS, and initial experiments have been really good! I'm finding my feed with popup boxes and CSS styling etc! However, I want to push the boundaries of what I know a bit ...
I'm trying to achieve a styled DIV (no problems there) that is rectangular, but has an arrow pointing to an icon on the nav bar, see image below, that includes the box border, and where the DIV itself can vary in height (although the arrow stays the same height/width at all times).
Can anyone point me in the right direction - or am I trying to do more than is possible!?
Thanks, in advance.

I have a login page presented as a modal view controller and when the UITextField become the first responder under portrait mode the view shifts to the left. I wonder why is this?
The code is very simple:
```
LoginViewController* lvc = [[LoginViewController alloc] init];
lvc.delegate = self;
[self.parentViewController presentModalViewController:lvc animated:YES];
[lvc release];
```
This is inside a UIViewController called OptionsViewController which is presented as a modalViewController as well. So basically I am presenting a modalViewController from a modalViewController

I have this problem with one of my UILabels, I would like to have the text that it displays begin being drawn at the top left of the label rather than the middle left.
Current screen:
As you can see the word "Description" in the label appears in the centre and to the left of the label. I would like it to start at the top-left instead. How do I implement this either programatically or in IB?
Thanks,
Jack

I am doing a school project in C# apps and I decided to create a ticketing system.
I want to impress my teacher (^^) so I decided to add a database for my app.
I have a month to do this so i think I can learn it since I don't have any prior experience with databases.
Could you tell me how to do it? Below is my app, I want to send the info in the `TextBox` to a database
I already followed the instructions in MSDN which basically tells you how to add a data source in your app. I added northwind dataset to my app, but I don't know what to do with it and how will it be useful with my app...

So I'm trying to write a Python implementation of the A* algorithm. My algorithm finds the path to the target without trouble, but when I get the program to visualize the closed and open lists, I notice that the closed list, whenever the obstacles are a little complicated, will balloon into a large, perfect diamond shape. In other words, my algorithm is adding nodes to the closed list that are significantly further from the target than any of the neighbors of the "expected" closed list should be.
To illustrate, when a point in the closed list is (2, 1) away from the target, but a wall is blocking the way, the algorithm will add both the node at (2, 2) away from the target (to try and get over the wall) and the algorithm at (3, 1) away from the target... for no good reason, since it's clearly further.
I'm not sure what I'm doing wrong. This distance calculation is meant to use the "Manhattan method" (imperfect for my purposes, but it shouldn't be causing such problems), but other methods continue to offer the same problem (or indeed worse problems).
```
def distance(self, tile1, tile2):
self.xDist = abs(tile1.col * TILE_SIZE - tile2.col * TILE_SIZE)
self.yDist = abs(tile1.row * TILE_SIZE - tile2.row * TILE_SIZE)
self.totalDist = self.straightCost * (self.xDist + self.yDist)
return self.totalDist
```
The code for filling the closed list looks like this. Here, .score[2](https://i.stack.imgur.com/gFhQa.jpg) is the H value, calculated using the distance method shown above.
```
while self.endTile not in self.openList:
self.smallestScore = MAX_DIST * 50
self.bestTile = None
for tile in self.openList:
if tile.score[2] <= self.smallestScore:
self.bestTile = tile
self.smallestScore = tile.score[2]
self.examine(self.bestTile)
```
The "examine" function adds the examined tile to the closed list and its viable neighbors to the open list, and seems to be working fine. The algorithm appears to be admitting all tiles with an H score of X (where X varies depending on the complexity of the maze the target is set in).
Slowing it down to a node-by-node visualization basically reveals that it is filling in an area of size X, and finds the path when the entrance into the maze is hit by the fill. I really have no clue what I'm doing wrong, and I've been trying to puzzle this out for two days now.
EDIT: in the interest of solving the problem, here is a fuller extract of code. This is the examine() function:
```
def examine(self, tile):
#Add the tile to the closed list, color it in, remove it from open list.
self.closedList.append(tile)
tile.color = CLOSED
pygame.draw.rect(windowSurface, tile.color, tile.rect)
pygame.display.update(tile.rect)
self.openList.remove(tile)
#Search all neighbors.
for a, b in ((tile.col + 1, tile.row), (tile.col - 1, tile.row),
(tile.col + 1, tile.row + 1), (tile.col + 1, tile.row - 1),
(tile.col - 1, tile.row + 1), (tile.col - 1, tile.row - 1),
(tile.col, tile.row + 1), (tile.col, tile.row - 1)):
#Ignore if out of range.
if a not in range(GRID_WIDTH) or b not in range(GRID_HEIGHT):
pass
#If the neighbor is pathable, add it to the open list.
elif self.tileMap[b][a].pathable and self.tileMap[b][a] not in self.openList and self.tileMap[b][a] not in self.closedList:
self.where = abs((a - tile.col)) + abs((b - tile.row))
if self.where == 0 or self.where == 2:
self.G = tile.score[1] + self.diagCost
self.H = self.distance(self.endTile, self.tileMap[b][a])
self.F = self.G + self.H
elif self.where == 1:
self.G = tile.score[1] + self.straightCost
self.H = self.distance(self.endTile, self.tileMap[b][a])
self.F = self.G + self.H
#Append to list and modify variables.
self.tileMap[b][a].score = (self.F, self.G, self.H)
self.tileMap[b][a].parent = tile
self.tileMap[b][a].color = OPEN
pygame.draw.rect(windowSurface, self.tileMap[b][a].color, self.tileMap[b][a].rect)
pygame.display.update(self.tileMap[b][a].rect)
self.openList.append(self.tileMap[b][a])
#If it's already in one of the lists, check to see if this isn't a better way to get to it.
elif self.tileMap[b][a] in self.openList or self.tileMap[b][a] in self.closedList:
self.where = abs((a - tile.col)) + abs((b - tile.row))
if self.where == 0 or self.where == 2:
if tile.score[1] + self.diagCost < self.tileMap[b][a].score[1]:
self.tileMap[b][a].score = (self.tileMap[b][a].score[0], tile.score[1] + self.diagCost, self.tileMap[b][a].score[2])
self.tileMap[b][a].parent = tile
print "parent changed!"
elif self.where == 1:
if tile.score[1] + self.straightCost < self.tileMap[b][a].score[1]:
self.tileMap[b][a].score = (self.tileMap[b][a].score[0], tile.score[1] + self.straightCost, self.tileMap[b][a].score[2])
self.tileMap[b][a].parent = tile
print "parent changed!"
```
And this is a newer version of the iteration that slows down so I can watch it progress. It is meant to find the node with the lowest score[0] (score is a tuple of F, G, H scores).
```
def path(self):
self.openList.append(self.startTile)
self.startTile.score = (self.distance(self.startTile, self.endTile), 0, self.distance(self.startTile, self.endTile))
self.examine(self.openList[0])
self.countDown = 0
while self.endTile not in self.openList:
if self.countDown <= 0:
self.countDown = 5000
self.smallestScore = MAX_DIST * 50
self.bestTile = self.startTile
for tile in self.openList:
if tile.score[0] <= self.smallestScore:
self.bestTile = tile
self.smallestScore = tile.score[0]
self.examine(self.bestTile)
else:
self.countDown -= timePassed
```
The following is an image illustrating the excess search area, using `self.totalDist = self.diagCost * math.sqrt(pow(self.xDist, 2) + pow(self.yDist, 2))`
Alternatively, removing the TILE_SIZE constant from the equation gets me this equally inefficient-looking search area:
It seems to me that it shouldn't be searching all that extra area - just the area immediately surrounding the obstacles.

On a web page that I am creating, I want to fill a rectangular area (let us say, the top half of the web page visible in a typical browser window) with about a hundred small rectangles:
1. Each rectangle (let us call this a cell) has its own colour, some text written inside it, and a border which distinguishes it from its neighbours.
2. The colour, shape and size of each cell, and the text which appears inside it is part of the input for making the web page : these depend on the user who is currently logged in, and changes periodically with time.
Given the data for all the hundred cells, how do I draw (and redraw) them on the web page? What technology should I use? HTML Tables/JavaScript/JQuery UI/HTML5 Canvas/ ... ?
My background: I am reasonably comfortable with programming in general, but am not used to any of the newer technologies used for creating web pages, apart from basic html, some php, and JavaScript played by the ear. I will learn whatever is needed to get this done well.
Edit: In response to hamlin11's question: The cells do not have any relationship to one another in general, except that they are guaranteed to fill the rectangular area. Here is an (imperfect) example of what they might look like, without the colours:

I understand that a user can own a process and each process has an address space (which contains valid memory locations, this process can reference). I know that a process can call a system call and pass parameters to it, just like any other library function. This seems to suggest that all system calls are in a process address space by sharing memory, etc. But perhaps, this is only an illusion created by the fact that in high level programming language, system calls look like any other function, when a process calls it.
But, now let me take a step deeper and analyze more closely on what happens under the hood. How does compiler compile a system call? It perhaps pushes the system call name and parameters supplied by the process in a stack and then put the assembly instruction say "TRAP" or something -- basically the assembly instruction to call a software interrupt.
This TRAP assembly instruction is executed by hardware by first toggling the mode bit from user to kernel and then setting the code pointer to say beginning of interrupt service routines. From this point on, the ISR executes in kernel mode, which picks up the parameters from the stack (this is possible, because kernel has access to any memory location, even the ones owned by user processes) and executes the system call and in the end relinquishes the CPU, which again toggles the mode bit and the user process starts from where it left off.
Is my understanding correct?
Attached is rough diagram of my understanding:

Ideally I could also use a plugin that uses hardware accelerated css transformations with a fallback to jquery's own in unsupported browsers. Please explain how you would do it conceptually if you can.
I'm thinking to animate the button larger somehow to the width of the container it will flip to, then shrink the height anchored in the center to a line and then do the opposite to the panel that will appear.

I'm using Less Framework 4 for two websites I'm designing. In both designs I want to apply a 5 pixel border both on top and bottom of the document.
The problem: because of the styles applied to , I'm applying the border-bottom and border-top to the object, so the bottom border never sticks to the bottom of the page like it would happen in a usual sticky footer situation.
Here are the screenshots for the two cases:
[](https://i.stack.imgur.com/HQq2r.png)
Here's the (LESS) CSS I'm using for html and body: pastie.org/private/us5x1vhjnwzq6zsiycnu2g
```
html {
border-top: solid @black 10px;
border-bottom: solid @black 10px;
background: url('img/bg.png') repeat;
}
body {
width: @8col;
margin: 0px auto;
padding: 100px 48px 84px;
background: @white;
color: rgb(60,60,60);
-webkit-text-size-adjust: 100%; /* Stops Mobile Safari from auto-adjusting font-sizes */
font: 13px/20px 'OftenRegular';
-webkit-tap-highlight-color: @green;
}
```
I've tried using `height: 100%` both for the `body` and `html` objects, but here's how it looks live: [http://prikonline.be/prikactie/](http://prikonline.be/prikactie/)

Here is a screenshot from Evernote. It appears to have (but i might be wrong) a custom UINavigationBar as well as a custom UITabBar.
A quick glance at the apps on my phone shows i could use a screenshot of Instagram, Path, DailyBooth, ...
[From the docs:-](http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/NavigationControllers/NavigationControllers.html)
> Because managing the navigation bar is
the responsibility of the navigation
controller, direct modification of the
navigation bar itself is considered
off limits for the most part.
Does Apple regard this kind of thing as grounds for AppStore refusal?

I want to program a daemon-manager that takes care that all daemons are running, like so (simplified pseudocode):
```
void watchMe(filename)
{
while (true)
{
system(filename); //freezes as long as filename runs
//oh, filename must be crashed. Nevermind, will be restarted
}
}
int main()
{
_beginThread(watchMe, "foo.exe");
_beginThread(watchMe, "bar.exe");
}
```
This part is already working - but now I am facing the problem that when an observed application - say foo.exe - crashes, the corresponding system-call freezes until I confirm this beautiful message box:
This makes the daemon useless.
What I think might be a solution is to make the main() of the observed programs (which I control) "uncrashable" so they are shutting down gracefully without showing this ugly message box.
Like so:
```
try
{
char *p = NULL;
*p = 123; //nice null pointer exception
}
catch (...)
{
cout << "Caught Exception. Terminating gracefully" << endl;
return 0;
}
```
But this doesn't work as it still produces this error message:
("Untreated exception ... Write access violation ...")
I've tried SetUnhandledExceptionFilter and all other stuff, but without effect.
Any help would be highly appreciated.

I'm currently migrating a web application from a database-based internationalization approach (each word having an entry in the translation table, and the actual translation) to one based on [Zend_Translate](http://framework.zend.com/manual/en/zend.translate.html) and CSV files.
I need to provide a end-user friendly way to update those translations quickly and easily. Ideally, to minimize the risk of breaking stuff, users would not edit the CSV files directly, but be shown a nice form with fields.
Do you know a standalone, PHP-based, end-user compatible translation frontend that supports one of the adapters `Zend_Translate` has to offer - ideally gettext or csv?
Something like Python's/Django's [Rosetta](http://code.google.com/p/django-rosetta/) but in PHP? Rosetta does exactly what I need:
but I would very much like to stay with PHP here for server setup reasons.
[SimplePO](http://code.google.com/p/simplepo/) looks like it goes in the right direction, but is too simple - it doesn't seem to be able to handle multiple languages and catalogs, and plurals.

I need to create a plot like in this image:
I wrote this code:
```
close all
x = [NaN 1 3 7 9 23 8];
y = [NaN 2 6 7 8 2 1];
z = [NaN 1 4 5 5 4 1];
for n = 1:length(z)-1
x1 = x(n);
x2 = x(n+1);
y1 = y(n);
y2 = y(n+1);
z1 = z(n);
z2 = z(n+1);
p = patch([x1 x2 x2 x1], [y1 y2 y2 y1], [0 0 z2 z1], [0 1 1]);
set(p, 'LineStyle', 'none');
plot3([x1 x2], [y1 y2], [z1 z2], 'b-', 'linewidth', 3);
hold on
end
view(3);
light
```
And I get this:
This is okay, but every patch face has a solid color, where I would like to have a color gradient based on the Z value, like in the first image where lowest z values are azure and highest z values are white (with a gradient from lowest to highest).
How can I modify my script to get this effect?

How can I fill patch objects using a colormap instead of a solid color?

So I look onto [OpenGL ES shader specs](http://www.khronos.org/registry/gles/specs/2.0/GLSL_ES_Specification_1.0.17.pdf) but do not see such...
For example - I created simple "pinch to zoon" and "rotate to turn around" and "move to move center" HYDRA pixel bender filter. it can be executed in flash. It is based on default pixel bender twirl example and [this](http://www.rphelan.com/2008/10/17/zoom-blur-pixel-bender-filter/):
```
<languageVersion: 1.0;>
kernel zoomandrotate
< namespace : "Pixel Bender Samples";
vendor : "Kabumbus";
version : 3;
description : "rotate and zoom an image around"; >
{
// define PI for the degrees to radians calculation
const float PI = 3.14159265;
// An input parameter to specify the center of the twirl effect.
// As above, we're using metadata to indicate the minimum,
// maximum, and default values, so that the tools can set the values
// in the correctly in the UI for the filter.
parameter float2 center
<
minValue:float2(0.0, 0.0);
maxValue:float2(2048.0, 2048.0);
defaultValue:float2(256.0, 256.0);
>;
// An input parameter to specify the angle that we would like to twirl.
// For this parameter, we're using metadata to indicate the minimum,
// maximum, and default values, so that the tools can set the values
// in the correctly in the UI for the filter.
parameter float twirlAngle
<
minValue:float(0.0);
maxValue:float(360.0);
defaultValue:float(90.0);
>;
parameter float zoomAmount
<
minValue:float(0.01);
maxValue:float(10.0);
defaultValue:float(1);
>;
// An input parameter that indicates how we want to vary the twirling
// within the radius. We've added support to modulate by one of two
// functions, a gaussian or a sinc function. Since Flash does not support
// bool parameters, we instead are using this as an int with two possible
// values. Setting this parameter to be 1 will
// cause the gaussian function to be used, unchecking it will cause
// the sinc function to be used.
parameter int gaussOrSinc
<
minValue:int(0);
maxValue:int(1);
defaultValue:int(0);
>;
input image4 oImage;
output float4 outputColor;
// evaluatePixel(): The function of the filter that actually does the
// processing of the image. This function is called once
// for each pixel of the output image.
void
evaluatePixel()
{
// convert the angle to radians
float twirlAngleRadians = radians(twirlAngle);
// calculate where we are relative to the center of the twirl
float2 relativePos = outCoord() - center;
// calculate the absolute distance from the center normalized
// by the twirl radius.
float distFromCenter = length( relativePos );
distFromCenter = 1.0;
// modulate the angle based on either a gaussian or a sync.
float adjustedRadians;
// precalculate either the gaussian or the sinc weight
float sincWeight = sin( distFromCenter ) * twirlAngleRadians / ( distFromCenter );
float gaussWeight = exp( -1.0 * distFromCenter * distFromCenter ) * twirlAngleRadians;
// protect the algorithm from a 1 / 0 error
adjustedRadians = (distFromCenter == 0.0) ? twirlAngleRadians : sincWeight;
// switch between a gaussian falloff or a sinc fallof
adjustedRadians = (gaussOrSinc == 1) ? adjustedRadians : gaussWeight;
// rotate the pixel sample location.
float cosAngle = cos( adjustedRadians );
float sinAngle = sin( adjustedRadians );
float2x2 rotationMat = float2x2(
cosAngle, sinAngle,
-sinAngle, cosAngle
);
relativePos = rotationMat * relativePos;
float scale = zoomAmount;
// sample and set as the output color. since relativePos
// is related to the center location, we need to add it back in.
// We use linear sampling to smooth out some of the pixelation.
outputColor = sampleLinear( oImage, relativePos/scale + center );
}
}
```
So now I want to port it into OpenGL ES shader. math and parameters are convertable into OpenGL ES shader language, but what to do with sampleLinear? what is analog for it in openGL ES shader languge?
So I had created something similar to my HYDRA filter... compatable with webGL and OpenGL ES shaders...
```
#ifdef GL_ES
precision highp float;
#endif
uniform vec2 resolution;
uniform float time;
uniform sampler2D tex0;
void main(void)
{
vec2 p = -1.0 + 2.0 * gl_FragCoord.xy / resolution.xy;
// a rotozoom
vec2 cst = vec2( cos(.5*time), sin(.5*time) );
mat2 rot = 0.5*cst.x*mat2(cst.x,-cst.y,cst.y,cst.x);
vec3 col = texture2D(tex0,0.5*rot*p+sin(0.1*time)).xyz;
gl_FragColor = vec4(col,1.0);
}
```
To see how it works get modern browser, navigate to [shadertoy](http://www.iquilezles.org/apps/shadertoy/) provide it with one texture ( `http://www.iquilezles.org/apps/shadertoy/presets/tex4.jpg` for example), paste my code into editable text aeria and hit ... Have fun. So.. now I have another problem... I want to have one image and black around it not copies of that same image... Any one knows how to do that?

How do I align the text in a RichTextBox?
Basically, the RTB contains:
"--testing"
"--TESTING"
"TESTING--"
"testing--"
Which all have the same number of characters, but have different alignments. How can I align them properly? Im fairly new to C# and confused since it aligned properly in Java's TextArea.
Thank you!

today I have a (simple) rendering problem for you. My current project gets datas from a file to generate a SVG file. Drawing things as polygon is pretty easy thanks to the SVG format, but I have a single problem: some of my polygons are in AND out of the page (meaning that some parts of them are displayed while the rest is not shown due to the fact they are out of the display limit). In order to optimize the final SVG file I need to reduce my polygon to a simpler form.
Consider the grey rectangle as my page.
Consider the green polygon as the thing I actually draw.
First picture shows you the thing that I actually have while the second picture shows you the final result I want to have.
First I thought to reduce my polygon in simple triangles in order to only draw points in the display limits. But I think a simpler solution exists... if you have it do not hesitate to share it with me :)
EDIT:
I have this tricky case to handle as well :
Thank you.

I have a screen with 4 seek bars ( As shown in the image below) . If the user moves B,C or D I calculate the average of the three and setProgress of A to the average. That was the easy part . What I would like to do is animate the progress bar A such that it does not jump in one shot (for eg from 25-75 ).
What are the recommended ways to animate A? I got a simple animation up but I am calling a TimerTask every 50ms to increment or decrement A by a unit value till I reach the required position. But its not very efficient.
Note: I have a custom Seekbar object using which I have created seekBar's A,B,C & D. Sorry I cant really share the code but will be happy to clarify anything.

First I need to make some color scribbles (the picture below is taken from M. Yang article's on Still Image Colorization) on an monochrome input image which is loaded into a PictureBox control.
I'm trying to use this to get the effect:
```
private void PictureBoxOnMouseDown(Object sender, MouseEventArgs e)
{
if((e.Button & MouseButtons.Left) == MouseButtons.Left)
{
this.MouseInitialPosition = e.Location;
}
}
private void PictureBoxOnMouseMove(Object sender, MouseEventArgs e)
{
if((e.Button & MouseButtons.Left) == MouseButtons.Left)
{
this.MouseLastPosition = e.Location;
}
this._PictureBox.Invalidate();
}
private void PictureBoxOnPaint(Object sender, PaintEventArgs e)
{
using(var pen = new Pen(Color.Red, 3.0F))
{
e.Graphics.DrawLine(pen, this.MouseInitialPosition, this.MouseLastPosition);
}
}
```
But that's giving me not quite I've been waiting for:
- I can't put several lines. Lines are not stored;- I'm overwriting line with line;
Second. I need to get all pixels from an image I've been drawing onto and filter them in some way (i.e. extract special ones). How do I store lines/scribbles onto image and then read the image efficiently?

i have small problem with autocomplete option in combobox. Everything is working correct, except that i want to work it diffrent :)
When I start typing in combobox, autusuggest working the way i like :
But when i first open combobox, and then start typing i get something like that:
What's more i can't pick item from autosuggest combobox, only from this list under.
AutocompleteMode is SuggestAppend
I'd like to have autosuggest like on the first picture, and in situations like picture 2, this first combobox list should be closed somehow..
