I need to make the date parts (dd, MMMM, yyyy) to be vertically aligned. I asked a question at [Fixed length of month and day in date format?](https://stackoverflow.com/questions/6515371/fixed-length-of-month-and-day-in-date-format) to insert padding letters, but I found that it doesn't help in case of proportional font (the width of the letters are different). For example, with Lucida Fax font:
Making different labels for different date parts is considering but it's too manual. It's hard to make the text wrapped if the column width is small....
Thanks

I just want to know if this is the proper way to go about splitting up widgets in GWT that get too large, or if I am missing the concept of widgets/proper GWT usage all together.
I started out with a single class (widget), . As became too large, I decided to branch off and make two classes , and , both of which just split off 's code into separate classes that still have access to the methods in :
This way, in my class, I can do something like this to add the and the to the tabs ([TabLayoutPanel](http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/TabLayoutPanel.html)) that are specified in the UiBinder of while allowing for and to have their own separate UiBinder specifications:
My question is: Is this proper? Part of me thinks "no" just because it's not a nice way of doing it. On the other hand it works just fine, and my web application is somewhat broken up into manageable "sections" which is what I wanted.
Thanks for any insight.

I have an SSRS Report. In which I have a table that has some rows. I want to calculate some things on the basis of these rows. See the sample table and things to be calculated:
Employment Period is calculated using `if( DayEmployed>730) then add 1 to count.` and `count` is the count of `Employment Periods greater than 2 Years`. How can I calculate this in SSRS?

I'm intending to display very large Images in Android. - to supply them as pdf - fails because not every handheld got a pdf-viewer preinstalled, and I don't want to require the users to install one.
So I have a png now that I want to display. I downloaded this image to test how it would be displayed the gallery. It was quite painful. It seems that the galery renders this picture only once, and if I Zoom in, I cannot read the text at all.
So I wrote a testActivity which simply has an ImageView nested in a LinearLayout. I put the image into the drawable and set it as ImageView's image-source.
Unforunately the app crashes immediatly, due to an "
```
ERROR/AndroidRuntime(8906): Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget"
```
I didn't expect that ONE single Image can be too large for`VM's memory`. I played a little bit around, set `ImageViews` size to `3998 & 2827px` , put the Image to `sdCard` and read it manually with a `fileInputStream`.
To my big surprise it now shows my image, but if I turn my I get the same `OutOfMemoryError` as before.
Can somewone point me the main difference between recieving a Bitmap through a `FileInputStream` or to set it as `ImageView's` source.
Also I'm not able to scroll comfortable with two parent `scrollViews`
I searching for a simple solution to display `ONE large image` at a time with the ability to `scroll horizontal and vertical` while able to zoom in and out.
here is a sample of the image I want to display

I've been developing a WPF interface for the past year, and this week I've noticed I can no longer open the interface within Visual Studio 2010 without it hanging indefinitely. I'm wondering why this has just started happening. I've checked through the SQL settings for the data bindings and everything seems fine. Does anyone know of any of other options I have? I can't seem to cancel this endless loading.

When reading codes, I often run into a metadata file like the marked-red as in the below snapshot.
For the same code, when debugging, Visual Studio IDE will ask to browse for the definition code of the `.dll` file. I browse to the source of that `dll` and can continue to debug with that pointed-out source.
What I need is: When browing the code (NOT when debugging), I am able to browse/be-asked-to-choose the source of that `metadata` dll source code when call `Go to definition` and/or `Pressing F12` - I don't want to paintfully start a debug to be able to see the code of the dll.
I don't know how to do that or is it possible. Please help!

I do this query with NHibernate:
```
var test = _session.CreateCriteria(typeof(Estimation))
.SetFetchMode("EstimationItems", FetchMode.Eager)
.List();
```
An "Estimation" can have several "EstimationItems" (Quantity, Price and ProductId)
I'd like a list of "Estimation" with these constraints :
1. One line by "Estimation" code on the picture (ex : 2011/0001 and 2011/0003)
2. By estimation (means on each line) the number of "EstimationItems"
3. By Estimation (means on each line) the total price (Quantity * Price) for each "EstimationItems"
I hope the structure will be clearer with the picture below.
Thanks,

In my web applications i have to generate seven different type of forms. There is a big 7 level tree and from that each first level subnode is a separate form. So for this what i am thinking is to generate 7 different xml files and to display the form like below given image i will parse the particular xml and display it. In my xml there will be node id and for each user i will store his selected nodes in the table so that i can retrieve later in my account section.
My question now are: is this xml approach proper...? and what kind of xml should i generated so that maximum flexibility can be kept in xml.. eg if i keep attribute validation: required in any node than it becomes required field in the generated html. i have to make a parser for that.

i have some uibezierpaths. as paths, they don't really have thickness.
but, I am hoping to find a way to define an area around a path like the grayish areas around the lines in this picture
basically, i want to test whether drawn lines fall within the buffer zone around the lines.
i thought this would be simple, but it's turning out to be much more complex than i thought. I can use the CGPathApply function to examine the points along my path, and then getting a range +or- each point, but it's more complicated than that with angles and curves. any ideas?

Since we've converted all our source and header files to unicode, we're facing problems with german umlauts. Everything is fine in the source but QLabels and other gui components are showing umlauts garbled.
ISO-8859-1 source works fine but causes problems when switching between OSX and Windows.
Is there anything I have to set in the project file?

I am implementing a custom progress bar using a timer and the Quartz2d draw circle/fill circle functions. Basically, I am using `CGContextAddLines,CGContextAddArc,CGContextDrawPath` methods but with limited success.
My Progress bar is implemented as a circle with a black background. Activity in the progress bar is implemented as an internal, incrementing segment of purple color. The segment is drawn in increments from -90 degrees (as shown in the image) and finishing at 360 degree. Ten seconds after the progress activity completes I am trying to change the fill color of the circle back to black.
My problem is that even though I can completely fill the color with purple, I am having trouble resetting the black background of the circle after 10 seconds. Any help would be appreciated.

I have written a app in WPF. And I am using standard BlueTheme available on microsoft website for my application. The application looks great in Windows XP which is having Windows XP style. In the screenshot below we can see the buttons with round edges and evrything.
I then right clciked on my desktop and went to appearance and chose windows classic style. Then the application looks crap. All the buttons are now having square edges.
I think searched in internet and people had suggested to include PresentationFramework.Aero theme. But still the problem persists.
[Edits]
I have added the below line. Still it doesn't work !
```
<Window.Resources>
<ResourceDictionary Source="/PresentationFramework.Aero, Version=3.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />

In Swing, I'm trying to use a `BoxLayout` or equivalent linear container, but the items in the container are stretching vertically. Inside my application, I don't want them to stretch vertically.
I know i could set a preferredSize or maximumSize on components, but the following code is just a reproducer, and I can't hard-code or maximize the size of the components, which are in reallity more complex and . And I just can't use a `BorderLayout` with the `BorderLayout.TOP` position, because no scroll bars will ever show if I do that. And I might need scroll panes.
---
So I tried to use the `fillers` in a `BoxLayout` as explained in [Using Invisible Components as Filler](http://download.oracle.com/javase/tutorial/uiswing/layout/box.html#filler), but it just doesn't work. Although in the Oracle documentation, it seemed to be exactly what I needed. Here are my attempts:
```
import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
public class TestBoxLayout implements Runnable {
public static void main(String[] args) {
SwingUtilities.invokeLater(new TestBoxLayout());
}
@Override
public void run() {
JFrame f = new JFrame("test box layout");
JPanel b = new JPanel();
b.setLayout(new BoxLayout(b, BoxLayout.PAGE_AXIS));
b.add(new JTextField("field 1"));
b.add(new JTextField("field 2"));
b.add(new JTextField("field 3"));
b.add(Box.createVerticalGlue());
f.setContentPane(b);
f.setSize(500, 200);
f.setVisible(true);
}
}
```
This is the result I get:
---
I tried to use the [Box](http://download.oracle.com/javase/6/docs/api/javax/swing/Box.html#Box%28int%29) class instead of `JPanel` with `BoxLayout`, but the visual result is exactly the same. Here is my second try:
```
import javax.swing.Box;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
public class TestBox implements Runnable {
public static void main(String[] args) {
SwingUtilities.invokeLater(new TestBox());
}
@Override
public void run() {
JFrame f = new JFrame("test box");
Box b = Box.createVerticalBox();
b.add(new JTextField("field 1"));
b.add(new JTextField("field 2"));
b.add(new JTextField("field 3"));
b.add(Box.createVerticalGlue());
f.setContentPane(b);
f.setSize(500, 200);
f.setVisible(true);
}
}
```

Does anyone know how I can and make them work ? A fix on the given code would be fantastic.

I've been trying to find what is the TrueType font behind Java's logical Monospaced font
on a Windows XP system.
The reason is that I use this font as my code editor's default font in IntelliJ Idea 10
on Windows XP and I recently moved to an Ubuntu system and want the same font in
Intellij Idea.
Currently on Ubuntu I get Courier New as the TrueType of Monospaced, and it is clearly
not the same font as the one used on Windows XP.
Could you please help ?
Thank you.
To be clear, I'm trying to have the Monospaced 12pt WinXP look the same on Ubuntu.
As you can see, the Monospaced 12pt WinXP isn't like any of the other versions.
Follow link for image of the different font appearance:

Having been struggling trying to bulkload data to the datastore, I have reached the point where expert help is needed.
I don't think what is am doing is tricky, I have the following configuration file:
and when I use the appcfg.py command, the error messages end with:
```
File "config.txt", line 1
python_preamble:
^
Syntax error: invalid syntax.
```
I have used a .txt file as it is faster to edit in notepad initially - I don't know if that is a problem and the remote_api for the appspot all seems to be okay.
I am thinking it is a fairly fundemental problem as it has stopped working at the top line. I removed the comment lines at the top of the original file - maybe that caused it.
I have tried to find working examples to set me right but they all seem to follow the syntax above, or where they are slightly different, I have tried both variants.
Help on bulkloading for my first cloud app would be much appreciated.
Thanks in advance for anyone taking time to read my post whether they solve it or not.

I have a text field with a set height and width and that allows word wrapping. When I add text to it, I dynamically change the font size until the height of the text is smaller than the height of the box, allowing it to properly fit. The problem I am running into is that the box is fairly thin by necessity, and some longer words (like "Australia") are broken during the word wrap. So, perhaps "Australi" will show up on the first line, and "a" on the second line. However, because they satisfy the height requirement, they aren't shrunk any more. I need a way to detect this and continue shrinking these cases so they fit without the break. Here is the code for dynamically shrinking the text to fit the height:
```
text.wordWrap = true;
text.autoSize = TextFieldAutoSize.CENTER;
while(text.height > textBoxVal) {
myFormat.size = Number(myFormat.size) - 2;
text.defaultTextFormat = myFormat;
text.setTextFormat(myFormat);
}
```
This works fine. The problem with my approach to the next step (shrinking if horizontal constraints are not met because of a word being split) is that by leaving `text.wordWrap` set to true, the longer words will still break and never be resized, but setting it to false means that the other boxes that were fine before because of word wrap being on (like "United States") are now too long on a single line, and are shrunk when they shouldn't be. For what it's worth, here's my code to shrink horizontally (immediately follows above code):
```
text.wordWrap = false;
text.autoSize = TextFieldAutoSize.LEFT;
while(text.width > textBoxVal) {
myFormat.size = Number(myFormat.size) - 2;
text.defaultTextFormat = myFormat;
text.setTextFormat(myFormat);
}
```
Is there a better way to go about this? Perhaps some way to force ActionScript not to break words, etc?
To give an example, please look at the screenshot below:
This is using only the first code block, which ensures that the text fits into the box's vertical constraints. You can see that some boxes (like the first for the US) are fine, whereas some of the smaller ones (like the last few) are split. Using my second code block to resize the horizontal constraints makes no changes if word wrap is true, and will make all boxes (including ones that are fine, like the US) smaller than needed if word wrap is set to false.

One of my Android projects requires `oauth.signpost` artifact, so I have something like this in my `pom.xml`:
```
...
<dependency>
<groupId>oauth.signpost</groupId>
<artifactId>signpost-core</artifactId>
<version>1.2.1.1</version>
<scope>compile</scope>
</dependency>
...
```
The problem is that this depends on more artifacts, for instance: `org.apache.httpcomponents:httpclient:4.0.1`. The problem is that Android already provides that package and thus it makes my building process crash.
So, what I usually do is going to the dependencies configuration on IntelliJ and manually mark those redundant artifacts as instead of :
This process is annoying, not only because I have a lot of Maven dependencies, but also because sometimes IntelliJ what dependencies were market as and it will mark'em all as .
The only solution I see is to specify, in the `pom.xml`, which dependencies are and which are . But there are a lot of them, so it would take some time (also, I'd have to manually check which version is needed for each artifact, etc.).
So, is it a way to tell Maven to mark sub-dependencies as , while keeping main dependencies as ?

The references (GOF Design Patterns, Head First Design Patterns, [http://www.dofactory.com/Patterns/PatternObserver.aspx](http://www.dofactory.com/Patterns/PatternObserver.aspx)) that I've read regarding the observer design pattern stipulate that the concrete subject holds a reference to the concrete observer. Much like this:
```
class ConcreteObserver : IObserver
{
ConcreteSubject concreteSubjectInstance;
//other code, etc.
}
```
Now, if the concrete Subject is itself implements a Subject interface (or derives from some abstract Subject class) why not make the type in the ConcreteObserver be of that abstract/interface? I.e.
```
class ConcreteObserver : IObserver
{
ISubject concreteSubjectInstance;
//other code, etc.
}
```
Moreover, why not just make it a field in the (e.g.) `IObserver` interface?
Ultimately, given that the pattern itself seems to loosen the coupling of the Subject to its Observers, why does this appear not to be promoted when coupling an Observer to its subject?
Or is it? I am only basing this on examples that I have read.

I want to replicate Gowalla UI of the detail part (the table with Map & Directions) picture below
I replicate it with a table with a contentInset, set backgroundColor to clearColor, and change color of UITableViewCell in `- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath` to white, but the result
isn't what I expected the empty cells are white only the cells with content (a number return by `- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section` ) here is a result I got
Is there any way to set empty cell color or any guide on how to achieve this ?

I added Parent Settings File to the solutions folder. After that I unchecked there rule SA1101 in the parent file. Also I set "Do not merge with any file" in parent file, and set merge in the parent file in the project`s settings file.
But after I build project I get this error. I attached window with error and settings winwows - there are no overloads or something like this.
I really don`t now what I can do, to resolve this issue....
ADDED.
But in resharper all rules work normal. But when I try to build solutions - my settings are ignored.
I used StyleCop Version 4.5.24.0

I've created a in ; when creating the application I selected iPhone as the :
The application was created with the following files:
I designed the UI on the file and without adding any code in the files, the application is uploading immediately to the view and I'm very happy about it.
Now I want to add an . How do I do that?
(I knew how to do it in XCode 3, but I used some code in the Delegate file, and now if I try to use the same code it doesn't work because the template default implementation works differently - Apple uses and s and it goes directly to the iPhone.xib. I don't know how to go around it without changing the entire thing to the way it was done in XCode3)

I am trying to interface an ancient network camera to my computer and I am stuck at a very fundamental problem -- detecting the end of stream.
I am using `TcpClient` to communicate with the camera and I can actually see it transmitting the command data, no problems here.
```
List<int> incoming = new List<int>();
TcpClient clientSocket = new TcpClient();
clientSocket.Connect(txtHost.Text, Int32.Parse(txtPort.Text));
NetworkStream serverStream = clientSocket.GetStream();
serverStream.Flush();
byte[] command = System.Text.Encoding.ASCII.GetBytes("i640*480M");
serverStream.Write(command, 0, command.Length);
```
Reading back the response is where the problem begins though. I initially thought something simple like the following bit of code would have worked:
```
while (serverStream.DataAvailable)
{
incoming.Add(serverStream.ReadByte());
}
```
But it didn't, so I had a go another version this time utilising ReadByte(). The description states:
> Reads a byte from the stream and
advances the position within the
stream by one byte, or returns -1 if
at the end of the stream.
so I thought I could implement something along the lines of:
```
Boolean run = true;
int rec;
while (run)
{
rec = serverStream.ReadByte();
if (rec == -1)
{
run = false;
//b = (byte)'X';
}
else
{
incoming.Add(rec);
}
}
```
Nope, still doesn't work. I can actually see data coming in and after a certain point (which is not always the same, otherwise I could have simply read that many bytes every time) I start getting `0` as the value for the rest of the elements and it doesn't halt until I manually stop the execution. Here's what it looks like:
So my question is, am I missing something fundamental here? How can I detect the end of the stream?
Many thanks,
H.

I need to write a script in VBA so that if column B has a x (or just is filled) then goto the cell to the left of it and get the value, I want to do this on a worksheet and I want to be able to calculate the total cost of a project depending if its required.
I would run this on event of a button click, so I want it to get all the values, add them up, and display me the total, But ONLY for the values with a x (in column B).

I am trying to run my .NET 3.5 WinForms application on a Win7 x64. The application uses NHibernate and the System.Data.OracleClient to access an Oracle database. The Oracle client is 32bit.
When starting up the app I get the following error message
> Attempt to load Oracle client libraries threw BadImageFormatException.
This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
In response to that, I targetted my build to the x86 platform:
To my surprise, when trying to execute that new build on the Win7 platform.
The NHibernate assembly is loaded at runtime by `Assembly.Load("...");`.
Could it be that the NHibernate DLL still runs in 64 bit mode whilst the host exe runs in 32 bit mode. That sounds strange to me. Or could it be that for whatever reason, my application runs in 64 bit mode even though it was targeted to x86?
---
I checked my binary using CorFlags, and it is marked 32 bit:
```
Microsoft (R) .NET Framework CorFlags Conversion Tool. Version 4.0.30319.1
Copyright (c) Microsoft Corporation. All rights reserved.
Version : v2.0.50727
CLR Header: 2.5
PE : PE32
CorFlags : 3
ILONLY : 1
32BIT : 1
Signed : 0
```
I also checked it in Task Manager, and it has a `*32` suffix.
I also tried and used CorFlags to add the 32bit flag to assemblies that come with my application. It still yields the same error message.
I'm puzzled... puzzled... puzzled...

I have a problem in my hand.
I have a URL, And when i initiate the connect to this url and execute url.getContent().
The response is of type `sun.net.www.protocol.http.HttpURLConnection$HttpInputStream`
I tried to assign the output to `HttpURLConnectionHttpInputStream h = url.getContent()`. But i was unsuccessful.
I imported corresponding libraries to code, but still no luck.
If i inspect the url.getContent() in eclipse, it also shows the variable thei$0 in it.
All i need is a URL in this$0. But till now i am unable to retreive it.
In this$0 there is a variable names url and i am trying to fetch it.
I also have hard time understand this$0 and hoe to retrieve it.
After using the streams i get some non readable output

I currently have JTables nested in JScrollPanes like so:
My problem is that the number of rows in each table is variable when the table is created. What I want to do is make the JScrollpane smaller if the table is too short, but I want to keep it at a set size if the table is too long.
How can I accomplish this?

I have a somewhat complicated requirement for layout of a few Core Animation layers. Basically, I have two layers, with CGImage contents, that need to resize (preserving their aspect ratios), but also cling next to each other in the middle of their parent layer. I've illustrated this below.
(Both of my illustrations show the bounds of Layer A's and Layer B's image contents. It doesn't matter if the layer itself is sized larger.)
The closest I've come so far, using CAConstraintLayoutManager is to get them scaled properly, but centered in their half of the superlayer (below).
I'm getting them to this point with the code below:
```
layerA.contentsGravity = kCAGravityResizeAspect;
[layerA setConstraints:[NSArray arrayWithObjects:
[CAConstraint constraintWithAttribute:kCAConstraintMinX relativeTo:@"superlayer" attribute:kCAConstraintMinX],
[CAConstraint constraintWithAttribute:kCAConstraintMaxX relativeTo:@"superlayer" kcaConstraintMidX],
[CAConstraint constraintWithAttribute:kCAConstraintMinY relativeTo:@"superlayer" attribute:kCAConstraintMinY],
[CAConstraint constraintWithAttribute:kCAConstraintMaxY relativeTo:@"superlayer" attribute:kCAConstraintMaxY],
nil]];
layerB.contentsGravity = kCAGravityResizeAspect;
[layerB setConstraints:[NSArray arrayWithObjects:
[CAConstraint constraintWithAttribute:kCAConstraintMinX relativeTo:@"superlayer" attribute:kCAConstraintMidX],
[CAConstraint constraintWithAttribute:kCAConstraintMaxX relativeTo:@"superlayer" kcaConstraintMaxX],
[CAConstraint constraintWithAttribute:kCAConstraintMinY relativeTo:@"superlayer" attribute:kCAConstraintMinY],
[CAConstraint constraintWithAttribute:kCAConstraintMaxY relativeTo:@"superlayer" attribute:kCAConstraintMaxY],
nil]];
```
How can you resize two layers, and also align them?
One idea that occurred to me was to create a layer that contained A and B, laid out properly, with no margin around the edges, and then scale that. I can't figure out a way to do that, either, though.

I have a usb midi controller (uc-33e) and I have a working python script see below.
I would like to be able to control the variables of the python script using my usb controller does anyone have an example of this? I would like to use the "midi learn" function to automatically map a midi control to an object (like in Ardour which is a music program for linux) by ctrl-middle clicking the object and just turning the control on the usb midi controller to map it. But I'm also willing to hard code the midi CC into the python script if needed.

I am generating a figure that will be used as a column of labels to the right of a three-panel figure, and I would like the title of the figure to right-align as do the labels in the figure itself.
here is a minimal example in which I would like to right-align the title 'words'.
```
ggplot() +
geom_text(aes(y = 1, x = seq(4),
label = c('fee', 'fi', 'fo', 'fum'),
hjust = 1)) +
opts(title = 'words') +
coord_flip() +
scale_y_continuous(breaks = c(0,0), limits = c(0,1))
```
Which produces this:
The answer by @joran is helpful, but it does not align the words with the labels. changing his code from `hjust=1` to `hjust = 0.96` gets close, but this is more of a hack than a satisfying answer.
|
Is it possible to align the title of a ggplot to the right?

I've managed to write a limited video player able to view a .3gp file from internet. The video will be shown centered full screen, maintaining the video aspect ratio. Also, rotations don't interrupt the video, which keeps playing without problems.
Everything seems fine, but... on my HTC Legend when you rotate back to portrait, the video is corrupted, and instead of showing full screen it is displayed at its native pixel size. But rotating again to landscape works and is shown perfectly. Any ideas why? Unfortunately I don't have more hardware to test this on and I've run out of ideas to test.
You can get the full example source code from [https://github.com/gradha/Android-video-stream-rotation](https://github.com/gradha/Android-video-stream-rotation). Here are screen captures of me opening the application, rotating to landscape, touching the screen to display the video controls, then rotating back to portrait to see the corruption.

I use this fragent shader (inspired from some tutorial found on the NVIDIA site some time ago). It basically compute bi-linear interpolation of a 2D texture.
```
uniform sampler2D myTexture;
uniform vec2 textureDimension;
#define texel_size_x 1.0 / textureDimension[0]
#define texel_size_y 1.0 / textureDimension[1]
vec4 texture2D_bilinear( sampler2D texture, vec2 uv)
{
vec2 f;
uv = uv + vec2( - texel_size_x / 2.0, - texel_size_y / 2.0);
f.x = fract( uv.x * textureDimension[0]);
f.y = fract( uv.y * textureDimension[1]);
vec4 t00 = texture2D( texture, vec2(uv));
vec4 t10 = texture2D( texture, vec2(uv) + vec2( texel_size_x, 0));
vec4 tA = mix( t00, t10, f.x);
vec4 t01 = texture2D( texture, vec2(uv) + vec2( 0, texel_size_y));
vec4 t11 = texture2D( texture, vec2(uv) + vec2( texel_size_x, texel_size_y));
vec4 tB = mix( t01, t11, f.x);
vec4 result = mix( tA, tB, f.y);
return result;
}
```
It looks quite simple and strait-forward. I recently test it on several ATI cards (latest drivers ...) and I get the following result :
 
(Left : Nearest neighbor) (Right : sharder in use)
As you can see some horizontal and vertical lines appear it's important to mention these are not fixed in the view-port coordinates neither in the texture coordinates.
I had to several shaders to make them work correctly on ATI cards, it's seems NVIDIA implementation is a little more regarding code I wrote some time. But in this case I don't see what I should change !
Anything general I should know about differences between NVIDIA and ATI GLSL implementation to overcome this ?

This question is actually for Unity3D, but it can also be a more general question, so therefore I'm going to make this question as general possible.
Suppose I have a scene with a `camera (near = 0.3, far = 1000, fov = 60)` and I want to draw a skydome that is 10000 units in radius.
The object is not culled by the frustum of the camera, because I'm inside of the dome. But the vertices are culled by some shader somehow and the end-result looks like this:
Now my question is:
> what setting for any engine can I change to make sure that the complete object is drawn and not clipped by the far plane of the camera?
What I don't want is:

I'm trying to draw an arc on a canvas in Javascript, but I want to get rid of the line that Javascript automatically draws. With the line being drawn, there are two problems:
a) fill() malfunctions
b) It looks like a bow
Here's an image of what I have and what I want: 
The left is what I have in JS, the right is what I have in Java. The Java implementation is fairly inefficient and I would like to use the functions already available.
Here are the relevant JS functions:
```
function pointAt(center, l, theta){
return {
x : Math.sin(theta) * l + center.x,
y : Math.cos(theta) * l + center.y
};
}
function drawArc(ctx, center, l, theta, sweep, label, thickness){
var p0 = pointAt(center, l, theta);
var p1 = pointAt(center, l + thickness, theta);
var p2 = pointAt(center, l + thickness, theta + sweep);
var p3 = pointAt(center, l, theta + sweep);
ctx.fillStyle = "red";
drawPoint(ctx, p0);
ctx.fillStyle = "blue";
drawPoint(ctx, p1);
ctx.fillStyle = "green";
drawPoint(ctx, p2);
ctx.fillStyle = "yellow";
drawPoint(ctx, p3);
ctx.beginPath();
ctx.moveTo(p0.x, p0.y);
ctx.lineTo(p1.x, p1.y);
ctx.arc(center.x, center.y, l + thickness, theta, theta + sweep, false);
ctx.moveTo(p2.x, p2.y);
ctx.lineTo(p3.x, p3.y);
ctx.arc(center.x, center.y, l, theta + sweep, theta, true)
ctx.closePath();
ctx.fill();
ctx.stroke();
//TODO: draw label!!!
}
function drawPoint(ctx, p){
ctx.fillRect(p.x - 4, p.y - 4, 8, 8);
}
```
Here's a working implementation in Java:
```
private static void drawArc(Graphics g, Point center, int l, double theta, double sweep, String label, int thickness){
for (double i = 0; i < thickness; i+=.5) { //hardcoded
Point last = pointAt(center, l + i, theta);
for(double t = theta; t < theta + sweep; t+=.01){
Point cur = pointAt(center, l + i, t);
g.drawLine(last.x, last.y, cur.x, cur.y);
last = cur;
}
}
double t = theta + sweep / 2;
Point p = pointAt(center, l + 15, t);
int size = g.getFontMetrics().stringWidth(label);
BufferedImage img = new BufferedImage(size * 2, size * 2, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = img.createGraphics();
g2.setColor(Color.RED);
double rot = (Math.PI / 2 - t);
// System.out.println(rot / Math.PI + "PI");
boolean b = true;
if(rot < -Math.PI / 2){
rot += Math.PI;
b = false;
}
g2.setTransform(AffineTransform.getRotateInstance(rot, size, size));
g2.drawString(label, size, size);
g2.dispose();
if(!b)
size *= 1.75; //magic value or hardcoded???
g.drawImage(img, p.x - size, p.y - size, null);
}
```
So my question:
How do I turn the banana into a thick arc?

Is there any algorithm or trick of how to determine the number of gaussians which should be identified within a set of data before applying the expectation maximization algorithm?
For example, in the above illustrated plot of 2 - Dimensional data, when I apply the Expectation Maximization algorithm, I try to fit 4 gaussians to the data and I would obtain the following result.
But what if I wouldn't knew the number of gaussians within the data? Is there any algorithm or trick which I could apply so that I could find out this detail?

The probability distribution of the sum of two random variables, x and y, is given by the convolution of the individual distributions. I'm having some trouble doing this numerically. In the following example, x and y are uniformly distributed, with their respective distributions approximated as histograms. My reasoning says that the histograms should be convoluted to give the distribution of, x+y.
```
from numpy.random import uniform
from numpy import ceil,convolve,histogram,sqrt
from pylab import hist,plot,show
n = 10**2
x,y = uniform(-0.5,0.5,n),uniform(-0.5,0.5,n)
bins = ceil(sqrt(n))
pdf_x = histogram(x,bins=bins,normed=True)
pdf_y = histogram(y,bins=bins,normed=True)
s = convolve(pdf_x[0],pdf_y[0])
plot(s)
show()
```
which gives the following,
In other words, a triangular distribution, as expected. However, I have no idea how to find the x-values. I would appreciate it if someone could correct me here.

In CSS, we have a [box model](http://www.w3.org/TR/CSS2/box.html) to define how border, margin, padding, and fill contribute to the total width and height of a rectangle. I'm porting some of my HTML/CSS design into Flash and can't quite figure out what Flash's box model is. In Flash, I've created a rectangle with gradient fill and a non-scaling 1 pixel stroke. I'm trying to get pixel-perfect positioning and sizing, but the experience has been unpredictable. I'm not really seeing a pattern to the following questions. The answer really changes depending on the exact circumstances.
1. When you set x and y both to be 0, where does the border lay? Is it off the screen? Is it being cut in half by the origin? Or is it completely visible?
2. When you set width to 100, is the fill 98 wide or 100 wide?
3. What happens to the 1px thick border when the rectangle is not positioned at whole number coordinates?
```
var sh:Shape = new Shape();
sh.graphics.lineStyle(1.0, 0x00FF00, 1.0, false, LineScaleMode.NONE);
sh.graphics.beginFill(0xFF0000, 1.0);
sh.graphics.drawRect(0, 0, 100, 100);
sh.graphics.endFill();
addChild(sh);
sh.x = 10;
sh.y = 10;
```
I tried to create a 100x100 square at x:10, y:10. When I measured the total width and height in Photoshop, it came out to be 101x101. Strange! One would either expect the final dimensions to be 100x100 (border on inside) or 102x102 (border on outside).

I think I am starting to understand how to link functions written in C/C++ to . The problem I'm facing is that I don't know how to send error messages from my C wrapper to Mathematica. After searching in google I found this [MathLink Tutorial](http://www.edenwaith.com/development/tutorials/mathlink/ML_Tut.pdf).
Section 1.7 gave me an insight as to how to send error messages but I am getting weird results. Here is the code I am working with.
---
```
//File cppFunctions.h
#ifndef CPPFUNCTIONS_H
#define CPPFUNCTIONS_H
class Point {
public:
double x, y;
Point(){ x=y=0.0;}
Point(double a, double b): x(a), y(b) {}
};
class Line {
public:
Point p1, p2;
Line(void) {}
Line(const Point &P, const Point &Q): p1(P), p2(Q) {}
double distanceTo(const Line &M, const double &EPS = 0.000001){
double x21 = p2.x - p1.x; double y21 = p2.y - p1.y;
double x43 = M.p2.x - M.p1.x; double y43 = M.p2.y - M.p1.y;
double x13 = p1.x - M.p1.x; double y13 = p1.y - M.p1.y;
double den = y43*x21 - x43*y21;
if (den*den < EPS) return -INFINITY;
double numL = (x43*y13 - y43*x13)/den;
double numM = (x21*y13 - y21*x13)/den;
if (numM < 0 || numM > 1) return -INFINITY;
return numL;
}
};
#endif
```
The file cppFunctions.h declares the classes `Point` and `Line`. I have stripped this class to the bare minium except for the function that I want to use in . I want to find the distance from one line to another. This function is the C version of `lineInt` in [wireframes in Mathematica](https://stackoverflow.com/questions/6353337/mathematica-3d-wire-frames). To use this function in we need a wrapper function that obtains the input from and sends the output back to .
---
```
//mlwrapper.cpp
#include "mathlink.h"
#include <math.h>
#include "cppFunctions.h"
void ML_GetPoint(Point &P){
long n;
MLCheckFunction(stdlink, "List", &n);
MLGetReal64(stdlink, &P.x);
MLGetReal64(stdlink, &P.y);
}
void ML_GetLine(Line &L){
long n;
MLCheckFunction(stdlink, "List", &n);
ML_GetPoint(L.p1);
ML_GetPoint(L.p2);
}
double LineDistance(void) {
Line L, M;
ML_GetLine(L);
ML_GetLine(M);
return L.distanceTo(M);
}
int main(int argc, char* argv[]) {
return MLMain(argc, argv);
}
```
I created two helper functions: `ML_GetPoint` and `ML_GetLine` to help me obtain the input from . A line is obtained from a list containing two list. Each sublist is a list of 2 real numbers (a point). To try this function in Mathematica we need to more files.
---
```
//mlwrapper.tm
double LineDistance P((void));
:Begin:
:Function: LineDistance
:Pattern: LineDistance[L_List, M_List]
:Arguments: {L, M}
:ArgumentTypes: {Manual}
:ReturnType: Real
:End:
:Evaluate: LineDistance::usage = "LineDistance[{{x1,y1}, {x2,y2}}, {{x3,y3}, {x4,y4}}] gives the distance between two lines."
:Evaluate: LineDistance::mlink = "There has been a low-level MathLink error. The message is: `1`"
```
This file states that the function LineDistance will obtain the arguments manually and that it will return a real number. The last two lines are important. The first `Evaluate` declares the `usage` of the function. It gives a brief message about the function when `?LineDistance` is entered into . The other `Evaluate` is the one I wish to use whenever there is an error (more on this later).

I should have mentioned before that I'm using Mac OS X, I'm not sure how this will work on Windows. In the mlwrapper.cpp the main function needs a lot more code which you can find in one of the examples provided by .
In the terminal I know do this:

make > makelog.txt
make clean
```
This make the executable `mlwrapper`. Now we can start using Mathematica:
```
SetDirectory[NotebookDirectory[]];
link = Install["mlwrapper"];
?LineDistance
Manipulate[
Grid[{{
Graphics[{
Line[{p1, p2}, VertexColors -> {Red, Red}],
Line[{p3, p4}]
},
PlotRange -> 3, Axes -> True],
LineDistance[{p1, p2}, {p3, p4}]
}}],
{{p1, {-1, 1}}, Locator, Appearance -> "L1"},
{{p2, {2, 1}}, Locator, Appearance -> "L2"},
{{p3, {2, -2}}, Locator, Appearance -> "M1"},
{{p4, {2, 3}}, Locator, Appearance -> "M2"}
```
]
The output we obtain is the following:
Everything works fine as long as you enter the correct arguments. That is, 2 lists, each one being a list of 2 lists of 2 doubles. Maybe there is another way of obtaining the inputs, if you know how to please let me know. If we stick to this method all we need is a way of letting the user know if there are any errors. A very simple one is entering the incorrect input. Lets say I enter this:
```
LineDistance[{{0, 0}, {0}}, {{1, -1}, {1, 1}}]
```
The output is `$Failed`. How about the following:
```
LineDistance[{{1, -1}, {1, 1}}]
```
The output is `LineDistance[{{1, -1}, {1, 1}}]`. I'm guessing this happens because we described in `Pattern` section of the `.tm` that the function accepts two lists and since we only gave one it doesn't match the pattern. Is this true?
In any case, following the tutorial I found lets modify the file mlwrapper.cpp as follows:
```
#include "mathlink.h"
#include <math.h>
#include <string>
#include "cppFunctions.h"
bool ML_Attempt(int func, const char* err_tag){
if (!func) {
char err_msg[100];
sprintf(err_msg, "Message[%s,\"%.76s\"]", err_tag, MLErrorMessage(stdlink));
MLClearError(stdlink); MLNewPacket(stdlink); MLEvaluate(stdlink, err_msg);
MLNextPacket(stdlink); MLNewPacket(stdlink); MLPutSymbol(stdlink, "$Failed");
return false;
}
return true;
}
void ML_GetPoint(Point &P){
long n;
if(!ML_Attempt(MLCheckFunction(stdlink, "List", &n), "LineDistance::mlink2"))return;
if(!ML_Attempt(MLGetReal64(stdlink, &P.x), "LineDistance::mlink3")) return;
if(!ML_Attempt(MLGetReal64(stdlink, &P.y), "LineDistance::mlink4")) return;
}
void ML_GetLine(Line &L){
long n;
if(!ML_Attempt(MLCheckFunction(stdlink, "List", &n), "LineDistance::mlink1"))return;
ML_GetPoint(L.p1);
ML_GetPoint(L.p2);
}
double LineDistance(void) {
Line L, M;
ML_GetLine(L);
ML_GetLine(M);
return L.distanceTo(M);
}
int main(int argc, char* argv[]) {
return MLMain(argc, argv);
}
```
And add the following to the end of the mlwrapper.tm file
```
:Evaluate: LineDistance::mlink1 = "There has been a low-level MathLink error. The message is: `1`"
:Evaluate: LineDistance::mlink2 = "There has been a low-level MathLink error. The message is: `1`"
:Evaluate: LineDistance::mlink3 = "There has been a low-level MathLink error. The message is: `1`"
:Evaluate: LineDistance::mlink4 = "There has been a low-level MathLink error. The message is: `1`"
```
Now lets use make and try to make some mistakes in Mathematica.
I'm posting a screenshot of what output instead of writing everything.
Notice how we get different errors after we repeat the call. It seems that the function continues at the line after the error was encountered. If I don't use any of the other ML functions like in the function `ML_Attempt` and I only use the `MLEvaluate` to send the error tag then the MathLink is broken and I have to re-install the link. Does anyone know how to send error messages to from C?
---
## UPDATE:
Based on the answers that have been given and another useful [document](http://library.wolfram.com/infocenter/Books/3710/) (Chapter 8) I managed to make it work. The code isn't so pretty at the moment but this made me ask the following question. Is it possible to terminate a function earlier? In a regular C program if I encounter an error I would print an error message and use the `exit` function. Can we do something similar? If we use the `exit` function the link will be broken and we will have to re-install the function. Take the functions `ML_GetPoint` and `ML_GetLine` for example. If an error occurred here then there is no point on procedding doing the calculations in the main function `LineDistance`. We need to clear whatever error we have obtained, send a message to Mathematica specifying the error, quit for now and wait for the next call.

It's a long story, but I will try make it simple:
1. I generated MeterMaid XML files with SugarMMM; I chose only the Accounts module:
2. I converted above files to JMeter format with MeterMaid (I consolidated the tests into one file and named it "filename.xml"): ruby GenMeter.rb --inputfile=filename.xml --outputfile=filename.jmx
3. I did the necessary CSV setup. All the CSV file contains is the login details (usr,pwd) for testing concurrent user logins. This part works well indeed.
When I run the test, I can see that a whole bunch of `${}` variables are converted into corresponding values. Sadly, `${SUBPANEL_RELATE_MODULE_g1}` doesn't get resolved... here's what the GET url (from Listener component) looks like:
```
http://localhost/sugarcrm/index.php?module=${SUBPANEL_RELATE_MODULE_g1}&action=Popup&hide_clear_button=true&mode=MultiSelect&create=true&metadata=undefined
```
Note that it's not the only variable that isn't resolved. The following screenshot shows the other tests that fail, all also caused by other variables not replaced by their corresponding values:
Here's how this variable is set up (which is well before the time it's used):
Here's what [Debug Sampler](http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Debug_Sampler) says:

# this
It looks pretty awesome so i of course went but all i saw was a bunch of `script` tags and one single `canvas` tag with text saying "".
Why can't i see what is happening in the html? and do you have a rough idea of how they built this?

I didn't like any available solutions so I started to make my own wizard interface. I use a GroupBox for each step of the wizard but since every step (every GroupBox) must have the same structure and style, I decided to use custom controls.
Now I need a custom GroupBox which has these elements:
- A FlowLayoutPanel so the developer can put desired controls in it using the designer. (For example two TextBox controls so the user can enter a username and a password.)- A Label in that FlowLayoutPanel to describe the step.- A Button to go back.- Another FlowLayoutPanel that user can put custom buttons in.
Here is a preview:
# Problem #1
When I create a new UserControl and make it inherit the GroupBox, I can't get a GroupBox that I can put and position stuff in it. All I see in the designer is this message:
# Problem #2
Since I couldn't make it inherit GroupBox like I wanted it to, I tried doing it by putting a GroupBox in the custom UserControl. (I don't want this. I just did this so I could provide some screenshots.) After I did that, I had to EnableDesignMode on the FlowLayoutPanels so the developer could add controls in them by using the designer. The problem is that they also became movable and resizable (I don't want this. They are anchored properly and they should not be moved nor resized.) and when you try to move them you get "Object reference not set to an instance of an object." which is making it uglier:
# Problem #3
I want elements in the main FlowLayoutPanel to be centered. To do this, I had to put a control (the description label) and resize it to the width of the FlowLayoutPanel so the controls after it would be centered. (Messy workaround if you ask me. Doing this with TableLayoutPanel looked easier but their cells can only hold one element. You can add a Panel to make the cell hold more elements but then you lose centering.) The problem is that I have to set Anchor to None for every control I add. Can I hook something (like OnDesignerControlAdded???) to automatically set added control's Anchor to None?
All of your answers will help me build the open source project [Magician on GitHub](https://github.com/AlicanC/Magician) and many other open source projects powered by it. Thanks in advance for all of your efforts.

I know how to change the background color of a scrollbar:
```
<ScrollBar Height="27" Margin="36,96,12,0" Name="scrollBar1" Background="Red"></ScrollBar>
```
here is the picture with my red background:
How could I do the same thing with ScrollViewer? I have a grid inside my ScrollViewer and if I change the properties of ScrollViewer it seem to change the properties of the content inside my grid.
```
<ScrollViewer>
<Grid Name="Parent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
....
....
... etc
```
that produces:
with the content of my grid named Parent on the left. How could I place a red background on this ScrollViewer?

The nav div must be fixed vertically and sitting to the right side of container div.
Using `position:fixed;` and setting values left and top, you get the div to stay in the same place, but the left value depends since the parent div (page-container) gets centered.

I am trying to create a button which is capable of resizing itself depending on the size of the text within it. The button is defined by the HTML text below. The whole button is defined as a `<span>`, and has three constituent components: the left curved portion of the button, the center body of the button (houses the text and expands accordingly), and the right curved part of the button. The right and left parts of the button are actually mirror images of each other.
The current code looks completely fine on Firefox and IE8, but when I view it on IE7, the right curved part floats to the right (this is correct), but the left and center float to the left of the panel that the button is in. This is not correct, and I wish to remedy this. However, trying to deal with this problem since it's IE related is a major pain for me. Can anyone suggest a solution or a work-around? Here is a picture for the button. `xp-b-left` defines the left side of the button and `xp-b-right` the right side of the button.
This is how the button looks like on IE7:
This is how the button looks like on Chrome, FF and IE8+ (no left float and no superfluous space between text and edges within button):
```
<span class="xp-b-submit xp-b-submit-flt xp-l-il xp-b-right">
<span class="xp-b-leftSide">
<!---->
</span>
<a href="#" class="xp-t-bold" id="flightSubmitLink">
Search
</a>
<span class="xp-b-rightSide">
<!---->
</span>
</span>
```

```
.xp-b-submit-flt {
background: url("../../images/new_blue_button.png") no-repeat scroll -22px 50% transparent;
}
.xp-b-submit {
background-position: right -32px;

I am using the following code:
```
public final class TableCellRendererCenter extends DefaultTableCellRenderer {
public static final TableCellRenderer INSTANCE
= new TableCellRendererCenter();
protected TableCellRendererCenter() {
// Calling super
super();
this.setHorizontalAlignment(SwingConstants.CENTER);
}
}
```
on a JTable column:
```
TableColumnModel retrMod = ChartItemsTable.getColumnModel();
TableColumn retrCol = retrMod.getColumn(2);
retrCol.setHeaderRenderer(TableCellRendererCenter.INSTANCE);
retrCol.setCellRenderer(TableCellRendererCenter.INSTANCE);
```
and the look-and-feel does not match other column headers anymore:
Why? How can I solve this issue?
It seems like NetBeans is using `DefaultTableCellHeaderRenderer` which is coming from `package sun.swing.table;`
I read everywhere that I should not use sun packages. Grrrr... this does not help!
The suggestion of 0verbose produces the following:
Following eugener's suggestion, I updated my code as following:
```
public final class TableCellRendererCenter extends DefaultTableCellRenderer {
@Override
public Component getTableCellRendererComponent(
JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column) {
// returns component used for default header rendering
// makes it independent on current L&F
Component retr = table.getTableHeader().getDefaultRenderer().
getTableCellRendererComponent(
table, value, isSelected, hasFocus, row, column);
if ( JLabel.class.isAssignableFrom(retr.getClass()) ) {
JLabel jl = (JLabel) retr;
jl.setHorizontalAlignment(SwingConstants.CENTER);
}
return retr;
}
@Override
public void validate() {}
@Override
public void revalidate() {}
@Override
public void firePropertyChange(
String propertyName, boolean oldValue, boolean newValue) {}
@Override
public void firePropertyChange(
String propertyName, Object oldValue, Object newValue) {}
}
```
And I get this:
Look-and-feel is preserved and column header is centered !!! (Other column headers are centered too, but I can control this by making further tests on the `int row, int column` parameters).

I have this page: [http://jsfiddle.net/minitech/yU3aj/show/](http://jsfiddle.net/minitech/yU3aj/show/)
If you look in the source, the CSS defines that the `<header>` should have side padding of 135px on each side, and the content should have 135px margin on each side. Why does the content end up having double that in spacing?

Why does the padding of one element affect the margin of another?

<FIELD name="State" refname="System.State" type="String" reportable="dimension">
<WHEN field="Approval.Marketing" value="No">
<READONLY />
</WHEN>
<WHEN field="Approval.Quality" value="No">
<READONLY />
</WHEN>
<WHEN field="Approval.RD" value="No">
<READONLY />
</WHEN>
<WHEN field="Approval.System" value="No">
<READONLY />
</WHEN>
<WHEN field="Approval.ProgManagement" value="No">
<READONLY />
</WHEN>
</FIELD>
```
This causes the State field to become READONLY if any of the approval fields are set to "No" which is what I want. However it causes problems when creating a new requirement since the approvals are all "No" initially and thus the initial "Proposed" default for State doesn't get set due to READONLY condition. What I'd like is to do is add logic to the WHEN conditions above to them with the condition System.State="Proposed". I tried nesting WHEN clauses such as
```
<FIELD name="State" refname="System.State" type="String" reportable="dimension">
<WHEN field="System.State" value="Proposed">
<WHEN field="Approval.Marketing" value="No">
<READONLY />
</WHEN>
. . .
</WHEN>
</FIELD>
```
But this gets an error on import that clause cannot contain . How can I prohibit State change from to when any of the Approval fields are set to "No"
|
How can I prohibit State change from Proposed to Active in TFS Requirement work-item based on value of another field?

I am working on a game written in javaScript / jQuery. Part of my code draws a random polygon (an island) on a tile grid. I need to check if a point is inside the polygon.
I am using a point-in-polygon intersection script which I found in [several](https://stackoverflow.com/questions/2212604/javascript-check-mouse-clicked-inside-the-circle-or-polygon/2212851#2212851) [places](https://stackoverflow.com/questions/217578/point-in-polygon-aka-hit-test/2922778#2922778) on Stack Overflow (original [here](http://www.ecse.rpi.edu/Homepages/wrf/Research/Short_Notes/pnpoly.html)). This works fine in Firefox. In Chrome, there are points inside the polygon which the script says are not inside it.
In Firefox:
In Chrome (the island is different because they are randomly generated):
Please take a look at the source here, particularly the pointPolygonIntersect function:
[Point in Polygon Hit Test](http://www.matthewhollett.com/code/wonder-v1/chromebug.php)
Can anyone figure out why this is happening? The original script is in C, and I am using a JavaScript version - could this be causing the problem?

I have a bizzare issue, I have a DIV that scrolls inside my page... But within that div I have 'header' that is FIXED.... and because my layout is fluid (100%) wide,it is making the "FXED" div cover over the scrollbars of the div below....
What is the best way to fix this? I have attached a simple screenshot of what's going on... hope it helps. 
```
/* BLUE SECTION */
.floatingHeaderBox {
width: 100%;
}
/* RED BOX BELOW */
.contentBoxRight{
position:absolute;
width:80%;
left:20%;
height:100%;
background-color:#FFF;
border-left:1px solid #CCC;
margin-left:-1px;
}
.contentBoxRight{ overflow:auto; overflow-x:hidden; }

Any one knows a tool to find difference between 2 notebooks at the source level?
The compare notebooks tool in workbench 2 seems to work at the internal data structure level which is not useful for me. I am looking for tool that looks at differences at the source level (what one sees when looking at a notebook, i.e. not the FullForm).
I am using V8 of Mathematica on windows.

Here's the query:
```
SELECT top 100 a.LocationId, b.SearchQuery, b.SearchRank
FROM dbo.Locations a
INNER JOIN dbo.LocationCache b ON a.LocationId = b.LocationId
WHERE a.CountryId = 2
AND a.Type = 7
```
PK_Locations:
> LocationId
IX_Locations_CountryId_Type:
> CountryId, Type
PK_LocationCache:
> LocationId
IX_LocationCache_LocationId_SearchQuery_SearchRank:
> LocationId, SearchQuery, SearchRank
So it's doing a on Locations, using the covering index, cool.
But why it is doing a on the LocationCache covering index?
That covering index has LocationId, SearchQuery, SearchRank in the index (not as "Included columns").
Hover on the index scan:
This query needs to go in an indexed view served by a SQL Server FTS catalogue, consumed by an autocomplete plugin, so it needs to be 100% optimized.
At the moment that above query is taking 3 seconds. It should be < 0.
Any ideas?

i am currently having trouble with my object rotating to face another object.currently it works fine as in this picture, my object at the origin will be able to rotate and move to the object in the 3 quadrants except the quadrant with positive 90degrees to 180 degrees, my object will rotate a few full rotation for some time while moving to the object does anyone know why? the sentence that i use to rotate is `rotation += (foodLocationDegrees - (rotation - 90)) * .2;` whereby food is calculated using
```
var angle:Number = Math.atan2(foodTarget.y - y, foodTarget.x - x);
foodLocationDegrees =Math.floor((angle * 180 / Math.PI));
```
y and x being the object which is a fish, and foodtarget being a object of a food.
```
public function moveToFood():void
{
var dx:Number = x - _destinationX;
var dy:Number = y - _destinationY;
trace("Food location degree relative to fish mouth "+foodLocationDegrees);
var targetRotation:Number = 0;
if (foodLocationDegrees > 0 && foodLocationDegrees < 90)
{

I have a div called header that is set up with a fixed position. The problem is when I scroll the page the content of the page shows up behind the header (the header is transparent).
I know a lot about css, but cannot seem to figure this one out. I have tried setting overflow to hidden, but I knew it wouldn't work (and it didn't).
This is very hard to explain, so I did the best I could.
html:
```
<div id="header">
<div id="topmenu">Home | Find Feeds | Subscriptions</div>
</div>
<div id="container">
<div id="content">
testing
</div>
</div>
```
css:
```
#header {
margin:0 auto;
position: fixed;
width:100%;
z-index:1000;
}
#topmenu {
background-color:#0000FF;
height:24px;
filter: alpha(opacity=50);
opacity: 0.5;
}
#leftlinks {
padding: 4px;
padding-left: 10px;
float: left;
}
#rightlinks {
padding: 4px;
padding-right: 10px;
float: right;
}
#containerfixedtop {
width: 100%;
height: 20px;
}
#contentfixedtop {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height:20px;
}
#container {
position: relative;
top: 68px;
width: 100%;
height: 2000px;
overflow: auto;
}
#content {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height: 2000px;
}
```

I've got a data set that looks as follows:
The first column is an auto-increment primary key. The second column is an ID number for whatever, maybe 3 rocks with IDs 1, 2 and 3 respectively. (I probably should have used the standard customer and order example but oh well.) The third column is a date when I threw the rock. I track the date each time the rock is thrown, hence the multiple IDs (the second column) each with a throwing time.
I want a query to return the rock ID and most recent date for each ID. The result of course would have a single record for each ID - the one with the latest access time.
I'm struggling with the possible combination of "DISTINCT", "TOP 1" and "GROUP BY" clauses that gives the result I want.
|
How do I find the most recently dated record for each ID in a set of IDs where any ID can have multiple records each for a particular date?

When the list underlying my databound DXGrid is updated, the scrollbar of the grid updates but the body of the grid does not, at least not right away. As soon as I click on the grid scrollbar, the body does refresh.
To illustrate - here is my application in the initial state:
When I add four new objects to my underlying list, only the scrollbar changes:
Finally, when I press on the "down" button at the bottom of the scrollbar, the entire grid refreshes:
Expected behaviour: The grid should refresh properly whenever the underlying database list is updated, not much later when the user tries to interact with the list.
The Xaml for my GridControl looks like this:
```
<dxg:GridControl dxlc:DockLayoutControl.Dock="Client"
ItemsSource="{Binding Project.TimeSeries}">
<dxg:GridControl.Columns>
... omitted ...
</dxg:GridControl.Columns>
<dxg:GridControl.View>
<dxg:TableView Name="tableView1"
AllowEditing="False"
AllowColumnFiltering="True"
ShowAutoFilterRow="True"
ShowGroupPanel="False"
FocusedRow="{Binding SelectedTimeSeries, Mode=TwoWay}"/>
</dxg:GridControl.View>
</dxg:GridControl>
```
`DataContext` of the form is set to a `TimeSeriesPresenter`:
```
public class TimeSeriesPresenter : ITimeSeriesPresenter
{
public TimeSeriesPresenter(ITimeSeriesVisual view)
: base(view) { ... }
public BuilderProject Project
{ get { ... } set { ... } }
public TimeSeriesDefinition SelectedTimeSeries
{ get { ... } set { ... } }
```
and a `BuilderProject` looks like this:
```
public class BuilderProject : ViewModelBase
{
public IList<TimeSeriesDefinition> TimeSeries
{ get { ... } }
...
}
```
Both of these objects implement `INotifyPropertyChanged` and the properties are triggering the `PropertyChanged` event properly. So, everything just work, right?
Clearly the DXGrid is receiving some kind of update from the view model, because the scrollbar changes. But why doesn't it repaint entirely?
Is there some kind of "mode" required for a DXGrid to do DataBinding normally?
What am I missing?
### Update
All of my data objects inherit from `ViewModelBase` which implements the `INotifyPropertyChanged` interface. In addition to `TimeSeriesPresenter` and `BuilderProject` (shown above), here's a summary of `TimeSeriesDefinition`:
```
public class TimeSeriesDefinition : ViewModelBase
{
public string SeriesID
{
get { return mSeries; }
set {
if (!Equals(mSeries, value) {
mSeries = value;
OnPropertyChanged("SeriesID");
}
}
}
... etc ...
}
```

I am attempting to draw radials from the center of an ellipse in quartz.
```
CGContextSetRGBStrokeColor(ctx, 0.0, 1.0, 1.0, 1.0); //cyan stroke
CGContextSetLineWidth(ctx, 2.0);
CGContextFillEllipseInRect(ctx, oRect);
CGContextSaveGState(ctx);
CGPoint center = CGPointMake(CGRectGetMidX(oRect), CGRectGetMidY(oRect));
CGFloat maxX = CGRectGetMaxX(oRect);
for(int i = 0; i < 5; i++) {
CGContextBeginPath(ctx);
CGContextMoveToPoint(ctx, maxX, center.y);
CGContextAddLineToPoint(ctx, center.x, center.y);
CGContextClosePath(ctx);
CGContextStrokePath(ctx);
CGContextRotateCTM(ctx, degreesToRadians(5.0));
}
CGContextRestoreGState(ctx);
```
Result:
Instead of the line drawing emanating from the center of the ellipse, it shifts with each transformation of the matrix. Why is the center reset instead of rotated?

My page is having left side menu and right side content with links.
When the links in the content are clicked then i need an iframe loading the content in the link and come up so that it covers the right side div having the content.
This iframe should be minimized when not needed and should be visible like a bar at the bottom always floating and when reached bottom of page it should be visible above the footer bar.
Can anyone suggest me how to do this. If example is provided that will be much better.
Thanks,
Sandeep

I am using excel 2010 and retrieving data from SQL analysis service.
When I refresh the data from excel , rows become dynamics as it is bind to external datasource. I am adding a seperate columns with formula for summing total amount.
With increment or decrement of rows in excel , alignment of custom columns goes out.
How can I resolve this problem that summing of values become dynamic with adding and removal of rows ?
How to write a macro for doing this task ?
This what i am trying , but i am getting the following error :
```
Public Sub ProcessData()
Dim i As Long
Dim iLastRow As Long
Dim iStart As Long
With Sheet1
iLastRow = .Cells(.Rows.Count, "D").End(xlUp).Row
iStart = 5
For i = 1 To iLastRow + 1
If .Cells(i, "C").Value <> "" And .Cells(i, "B").Value <> "" Then
.Cells(i, "D").Value =
Application.Sum(.Range(.Cells(iStart, "C").Value + .Cells ( iStart, "B").Value))
iStart = i + 1
End If
Next i
End With
End Sub
```

Given the following contrived example:
I would like to query my data for all objects that are either cats or dogs. I want the result set ordered by name regardless of species, so fetching all cats then fetching all dogs won't do. I want to do this in a single query.
One way to do this would be to add a petType field to Pet, give every record a petType value that identifies the sub-entity it belongs to, then query like so:
```
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Pet"
inManagedObjectContext:myMOC];
[fetchRequest setEntity:entity];
// petType values: 1 = dog, 2 = cat, 3 = goldfish. Yuk.
NSPredicate *p = [NSPredicate predicateWithFormat:@"petType = 1 OR petType = 2"]
[fetchRequest setPredicate:p];
// etc...
```
But the mere thought of doing it that way makes me shudder. Is there a better way?
---
: Thanks to all those who've replied - there are some really good, well-thought out solutions here and I appreciate all of them.
To give this some context, the real data model is a little more complex than this (aren't they always), but it's pretty well organised. I've designed more than my fair share of data schemas in my time and I'm happy that the entities and their relationships are well considered. This issue has come about because (to extend the already shaky contrived example) the client originally wanted:
- - - -
So far, so good. But they also want a view showing a combined list of all cats and dogs "because little girls like cats and dogs". (Initially it was cats and goldfish, for the same reason.) There isn't really a way to naturally group that subset of the concrete entities; it's really rather arbitrary.
So far, Dave Dribin's "abstract intermediate entity" approach seems like the cleanest solution, although in my case I think it would feel somewhat artificial; really the only way you could truthfully label the intermediate entity would be as "ThingLittleGirlsLike"! :)

I realize that `ofstream` doesn't work on Windows 7 hidden file.
Here is the quick test code.
```
#include <fstream>
#include <iostream>
#include <tchar.h>
#include <windows.h>
int main() {
{
std::ifstream file2(_T("c:\\a.txt"));
if (file2.is_open()) {
std::cout << "ifstream open" << std::endl;
} else {
std::cout << "ifstream not open!" << std::endl;
}
}
// SetFileAttributes(_T("c:\\a.txt"), FILE_ATTRIBUTE_NORMAL);
SetFileAttributes(_T("c:\\a.txt"), FILE_ATTRIBUTE_HIDDEN);
{
std::ofstream file(_T("c:\\a.txt"));
if (file.is_open()) {
std::cout << "ofstream open" << std::endl;
} else {
std::cout << "ofstream not open!" << std::endl;
}
}
getchar();
}
```
Here is the output I am getting
```
ifstream open
ofstream not open!
```
If I am using `FILE_ATTRIBUTE_NORMAL`, `ofstream` will be opened successfully.
I do not run the program as Administrator. But, I do use the following linker option.
Having to turn for is important, if we do not start the application as Administrator. OS will help us to write the actual file to `C:\Users\yccheok\AppData\Local\VirtualStore\a.txt` instead of protected `C:\`
Does `ofstream` fail on Windows 7 hidden file, is an expected behaviour?

After running Canny edge detector on an image i'm getting clear lines. But the Hough line function seems to be missing out on pretty prominent lines when run on the Canny edgemap image.
I'm keeping only vertical and horizontal Hough lines (a tolerance of 15 degrees). Lots of extra lines are coming up but clearly visible lines bounding the rectangles are not being picked up.
Here's the snippet:
```
cvCanny( img, canny, 0, 100, 3 );
lines = cvHoughLines2( canny, storage, CV_HOUGH_PROBABILISTIC, 1, CV_PI/180, 35, 20, 10 );
```
The main intention is to detect the rectangular boxes that denote the nodes of the linked list. However the squares.c sample program will detect only perfect rectangles, not if an arrowhead is touching the rectangle boundary.
Could you please explain the sort of changes to Hough line function which will help me get hough lines corresponding to clearly visible lines in Canny edge image?

I'm trying to create a WCF data service that exposes a database represented by an entity framework model, and running into a problem running HTTP POST requests against a table with multiple 1-* inheritances.
The entity framework table is as follows:
Most tables with one parent entity can be accessed via POST to the parent URI, i.e., '[http://url/data.svc/parent(id)](http://url/data.svc/parent(id))'. The problem I'm running into is I can't use this method due to the multiple inheritances. I could allow one FK to be nullable, and update with a separate PUT operation, but that's just bad code.
I'm creating the HTTP request using JSON. Here's an example of what I've been trying
```
POST http://url/data.svc/Order_Item HTTP/1.1
User-Agent: Fiddler
Accept: application/json
Content-Type: application/json
{"Count": 2, "Item": {"uri": "http://url/data.svc/Items(ID)"}, "Order": {"uri": "http://url/data.svc/Order(ID)"}}
```
The InitializeService method is as follows:
```
public static void InitializeService(DataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
}
```
I know that this is probably pretty simple, but could someone help me figure the syntax on posting linked entities? Thank you in advance

see the screen shot is clear to understand what I mean
you can see I add a navigationItem in my pop view
I wish I can dismiss the pop view
But it seems only tab the cell under the pop view
The pop view will dismiss,I try to add this method
```

```
It only remove the table view , the pop view frame is still there ,only without the content view
Any reply will be helpful : )
Thanks

I'll show you my problem by image. I have tableView in which i customize the UITableViewCell and tableViewCell having UILabel field. In this UILabel field data is coming by parsing the XML file data come completely but a little alignment problem it looks like a paragraph showing in image given below:-
and this in my code which is used to print data on this UItableViewCell's UILabel:-
```
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:@"TableCell13" owner:self options:NULL];
cell = nibLoadedCell;
}
titleLabel.text = aNewsInfo.title;
return cell; }
```
and I used Interface Builder (IB) for designing the cell i showing the setting by the image given blow for the UITableView cells UILabel :-
any one suggest me the method how can i rectify this problem.
Thanks in advance

FirstDriveFromMask (unitmask)
Description
Finds the first valid drive letter from a mask of drive letters.
The mask must be in the format bit 0 = A, bit 1 = B, bit 2 = C,
and so on. A valid drive letter is defined when the
corresponding bit is set to 1.
Returns the first drive letter that was found.
