This is the data I read from database into a datatable.
the datatable called table is now reshaped.
For every same/distinct UnitType + UnitZoom + MemberZoom I create a new Unit and read the MemberId`s into the MemberListId - this should happen in the Order given by the number of the MemberOrder. Sample data:
Unit1: A B C --> P1,P2
Unit2: 1 2 3 --> P9,P12,P4
Unit3: H23 B10 T15 -->X4,T5,Z3,Y1
My code for now that does not proper sort:
```
var groupedCollection = table.AsEnumerable()
.GroupBy(row => new
{
UType = row.Field<string>("UnitType"),
UZoom = row.Field<string>("UnitZoom"),
MZoom = row.Field<string>("MemberZoom"),
MOrder = row.Field<int>("MemberOrder"),
// I DO NOT WANT the MemberOrder to be in the Group Key, but later on I use this Property to order by it...
});
var unitCollection = groupedCollection
.Select(g => new Unit
{
UnitType = g.Key.UType,
UnitZoom = g.Key.UZoom,
MemberZoom = g.Key.MZoom,
MemberIdList = g.Select(r => r.Field<string>("MemberId")).OrderBy(b => g.Key.MOrder).ToList(),
});
List<Unit> units = unitCollection.ToList();
```

My project needs a library which is able to read large amount of data
from 2D data Matrix .Now I am using Zxing which is
decoding only 2D data Matrix with less amount of data and not able to read
large amount of data in 2D Data Matrix.But its working fine with QR
codes with any amount of data
this is my 2D data Matrix data
Any other library is available for 2D data matrix scanning
I have downloaded libdmtx library but I don't know how can i use it with my project because it is a C file?
Please give me solutions for this
Thanks in Advance
this is my 2D data Matrix data
zxing 1.7 Not Working with these above code
I need other libraries to decode 2D data matrix of above type

I have not seen this before usually a map either loads or it doesnt because of some error. I am getting the map to load without errors but it is blank:
```
<script type='text/javascript' src='http://maps.google.com/maps/api/js?sensor=false&ver=3.0'></script>
<script type="text/javascript">
function initialize() {
var latlng = new google.maps.LatLng(43.9869349, -102.24306);
var myOptions = {
zoom: 6,
center: latlng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
</script>
<div id="map_canvas" style="width:100%; height:300px"></div>
```
Anyone else seen this or know what might be the culprit? The map itself is sitting in a div that I am show/hide with jQuery. Could that be the conflict?
## ANSWER
This was just a stupid conflict with the parent div where I had img {display:none} defined. Oops. .thanks everyone for trying to help.

I am using Delphi 2009.
I want to view the contents of a file (in hexadecimal) inside a memo.
I'm using this code :
```
var
Buffer:String;
begin
Buffer := '';
AssignFile(sF,Source); //Assign file
Reset(sF);
repeat
Readln(sF,Buffer); //Load every line to a string.
TempChar:=StrToHex(Buffer); //Convert to Hex using the function
...
until EOF(sF);
end;
function StrToHex(AStr: string): string;
var
I ,Len: Integer;
s: chr (0)..255;
//s:byte;
//s: char;
begin
len:=length(AStr);
Result:='';
for i:=1 to len do
begin
s:=AStr[i];
//The problem is here. Ord(s) is giving false values (251 instead of 255)
//And in general the output differs from a professional hex editor.
Result:=Result +' '+IntToHex(Ord(s),2)+'('+IntToStr(Ord(s))+')';
end;
Delete(Result,1,1);
end;
```
When I declare variable "" as (i know that char goes up to 255) I get results hex values up to 65535!
When i declare variable "" as or , it outputs different hex values, comparing to any Hexadecimal Editor!
Why is that? How can I see the correct values?
Check images for the differences.
: Professional Hex Editor.
: Function output to Memo.
Thank you.

I need to get performance counters from the network card. To make things easy, the user selects the needed adapter by typing an index number in a console application.
This is the code that gets the user input and creates performance counter instance
```
var connectionNames = NetworkCardLocator.GetConnectedCardNames().ToArray();
log.Debug("Please select one of the available connections");
log.Debug("--");
for (int i = 0; i < connectionNames.Count(); i++)
{
log.Debug(i + ". " + connectionNames[i]);
}
log.Debug("--");
var key = Console.ReadLine();
int idx = 0;
Int32.TryParse(key, out idx);
string connectionName = connectionNames[idx];
var networkBytesSent = new PerformanceCounter("Network Interface", "Bytes Sent/sec", connectionName);
var networkBytesReceived = new PerformanceCounter("Network Interface", "Bytes Received/sec", connectionName);
var networkBytesTotal = new PerformanceCounter("Network Interface", "Bytes Total/sec", connectionName);
```
This is how I select available adapters
```
internal static IEnumerable<string> GetConnectedCardNames()
{
string query = String.Format(@"SELECT * FROM Win32_NetworkAdapter");
var searcher = new ManagementObjectSearcher
{
Query = new ObjectQuery(query)
};
try
{
log.Debug("Trying to select network adapters");
var adapterObjects = searcher.Get();
var names = (from ManagementObject o in adapterObjects
select o["Name"])
.Cast<string>();
return names;
}
catch (Exception ex)
{
log.Debug("Failed to get needed names, see Exception log for details");
log.Fatal(ex);
throw;
}
}
```
Given I have selected the needed adapter, the code works on my machine (Win 2008 R2 Ent x64). It doesn't work on some of the VMs I use for testing (Win 2008 R1 DC x86). Any selection there gives me an exception (still works on my PC and VM Win 2008 R1 Std x86)
```
foreach (PerformanceCounter counter in counters)
{
float rawValue = counter.NextValue(); //thrown here
...
}

So I thought that an enum would help me with States. Basically, I have a little Sidebar app which has 3 states:
Minimized - Where you can see a small and colored rectangular Panel indicating the app is open on the desktop.
Preview - Which indicated the app is open, and you can see the logo.
Normal - where the whole sidebar can be seen.
Now, I have setup an enum like this:
```
public enum CurrentState
{
Minimized = 0,
Preview,
Normal
};
```
And I am trying to check the CurrentState and switch to another like this when the user clicks the always-visible panel:
```
// If Min=Set(Preview). If Preview=Set(Normal). If Normal=Set(Min).
if (State.HasFlag(CurrentState.Minimized))
{
State = CurrentState.Preview;
this.Location = new Point(
Screen.PrimaryScreen.WorkingArea.Right - _minimize.Size.Width - _logo.Size.Width,
this.Location.Y
);
}
else if (State.HasFlag(CurrentState.Preview))
{
State = CurrentState.Normal;
this.Location = new Point(
Screen.PrimaryScreen.WorkingArea.Right - this.Size.Width,
this.Location.Y
);
}
else
{
State = CurrentState.Minimized;
this.Location = new Point(
Screen.PrimaryScreen.WorkingArea.Right - _minimize.Size.Width,
this.Location.Y
);
}
```
And when the application loads, I set the initial value to:
CurrentState.Minimized;, like this:
```
CurrentState State = CurrentState.Preview;
```
So, this is the behavior:
If form is Minimized, Move it a bit so it is in Preview mode. If it is in Preview, move it a bit so it is in Normal mode. If it is in Normal mode, set it to Minimized again.
But, upon clicking the always-visible panel the first time, it works as expected. It sets it to Preview mode and moved the form a bit.
, that's as far as it goes. Once it's in Preview mode, it does not go to Normal mode upon clicking the Panel a second time, which means that it's currently impossible to get it to normal view.
Am I doing something wrong here?
Although this may be uncommon, it is logical, and I can't figure out where something is going wrong.
Here's a little visual to help better clarify what I mean:

I'm using SQL Server 2005. I have a series of product and pricing tables from which I draw a view that provides several line items for each product, depending on whether the item's markup is set at item level, category level, or department level. So an example of the output for a single item would be:
What I'd like some help with - if it's at all possible - is grouping the output or performing some additional query on it so that the three line items in my result are combined into a single line item, with all the possible markup levels on one line. I've been unable to think of a way to do this without requiring additional expensive server-side processing to create a temp table and apply some logic to it to combine the 3 lines into 1. The real issue is time, since iterating through a product database of over 30000 items and performing per-line steps on the whole thing strikes me as an extremely cumbersome way to do this.
If anyone might be able to help me out on this, I'd really appreciate it.

I'm running a simple load test with apache benchmark:
```
ab -n 1 http://localhost/mysite/index/index/
```
In my httpd.conf:
```
#mod_deflate enabled
LoadModule deflate_module modules/mod_deflate.so
#mod_deflate disabled
#LoadModule deflate_module modules/mod_deflate.so
```
- It looks like server without mod_deflate is performing better than with mod_deflate enabled (see "time taken for tests","Requests per seconds" and "time per requests").- Plus I dont understand why total transferred is bigger with deflate enabled
Please explain me
thanks

I'm using an image of a dart board in this example as it's a good example for what I am trying to achieve.
Is there any way in Java that part of an image can be highlighted? I achieved the below by using the `Magic Wand` in Paint.NET and added an outline to the selected part.
The 'problem' here is if I wanted to highlight every part of this dart board individually, I'm going to end up with a lot of pictures.
Is there some clever library out there that can do this programmatically so I have literally just the one image and can somehow point to some coordinates, it imitates the "magic wand" effect and adds an outline of my choice?
Without highlight:
With highlight:

I'm using gnuplot to profile my cuda program. I found especially the width plot feature helpful. It seems however that computeprof offers no way to export or customize the plots generated. Fortunately all the data is stored in csv format so I thought I could do it just myself using gnuplot or something similar. So now to my question: I couldn't find an example to pro create a plot of time blocks can you create such a plot using gnuplot and if so how?

I am having problem in managing UITableView. I 'm posting a screenshot here to briefly explain the problem. Image 1 shows the default View when First Time view Appears. When I tap on yellow button(Yellow Button is in a custom table section header view) I open an UIAlertView with table in it like shown in the image 2. Then selecting any option I insert a custom cell with a button,textfield and another button. I have a mutable Array for each section so when I select an option I add that string into the corresponding section array and reloadtable.See image 3. Now when I enter values in UITextfields the values replaced by another cells. See the two images below for understanding the problem. image 4. Also when I delete a cell and insert a new the textfield is preloaded with previous value.

I have an auto generated DropDownList from Entity Framework in a strongly typed view:
```
<div class="editor-field">
@Html.DropDownList("User_FK", String.Empty)
@Html.ValidationMessageFor(model => model.User_FK)
</div>
```
Here is the action code:
```
public ActionResult Create()
{
ViewBag.SystemMaster_FK = new SelectList(db.SystemMasters, "System_PK", "Name");
ViewBag.User_FK = new SelectList(db.Users, "User_PK", "NetworkLogin");
return View();
}
```
I need this list to display the names of people loaded from Active Directory. How do I customize the select list options seperately?

I need help on how to filter data in a database. I want a filter like in the excel spreadsheet.
For example, I have this sample code on how to get data from [w3school](http://www.w3schools.com/php/php_mysql_select.asp) on how to select data from database. Here is my sample code:
```
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("TableTest", $con);
$result = mysql_query("SELECT * FROM Colors ");
echo "<table border='1'>
<tr>
<th>Colors</th>
<th>Type</th>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['colors'] . "</td>";
echo "<td>" . $row['type'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
```
I also found this [sample](http://www.w3schools.com/php/php_ajax_database.asp) too in w3school, but I dont want to filter the database with a drop down.
I'd like to make it like an excel filter. When I select the column 'Colors' to filter on 'Red', it will display only the color red. So i was wondering if anyone could help me on how to start.
Thanks all

I nearly successfully migrated my vim settings form Linux (ubuntu) on Mac. What I liked was the latex-suite for vim with the forward (press the compiling buttons and the generated dvi file will jumo straightly to this position) and inverse search (press CTR and the left mouse button in the dvi file and it will jump right to the place in the code of the tex file where you pressed). Under Linux it is working but not under MacVim. Here is a picture of the error message:
Here are my .vimrc settings for the latex suite:
```
" LateX SUITE HACKS
" =================

```
I got these settings from [http://vim.wikia.com/wiki/Vim_can_interact_with_xdvi](http://vim.wikia.com/wiki/Vim_can_interact_with_xdvi)
I'm starting vim with an alias like:
```
alias vi='/Applications/MacVim.app/Contents/MacOS/Vim -g'
alias vim='/Applications/MacVim.app/Contents/MacOS/Vim -g'
```
It must have something to do with the xserver or maybe some wrong argument passing in the settings mentioned above. Hope someone can help me.

I have a select box in which it is very important that the background for each option has a specific color. The problem is that the select box is clicked, the selected option appears blue (same as the selected text color).
I've tried using a lot of selectors (:active, :focus, ::selection, [selected]) and I cannot find the way to change this behaviour. Any idea?
I guess this can be done with js, but there must be a CSS selector that works, right?

I am taking photo using , , and display it in . Its work properly.
But, After display image in UIImage. I am detecting faces using OpenCV from that displayed image.
It detect, but it returns the rotated image. I am not use any code for rotate the image. Its automatically rotate the image.
I want to stop rotating.
Here is my code.
```
+ (UIImage *) opencvFaceDetect:(UIImage *)originalImage {
cvSetErrMode(CV_ErrModeParent);
IplImage *image = [self CreateIplImageFromUIImage:originalImage];
// Scaling down
IplImage *small_image = cvCreateImage(cvSize(image->width/2,image->height/2), IPL_DEPTH_8U, 3);
cvPyrDown(image, small_image, CV_GAUSSIAN_5x5);
int scale = 2;
// Load XML
NSString *path = [[NSBundle mainBundle] pathForResource:@"haarcascade_frontalface_default" ofType:@"xml"];
CvHaarClassifierCascade* cascade = (CvHaarClassifierCascade*)cvLoad([path cStringUsingEncoding:NSASCIIStringEncoding], NULL, NULL, NULL);
CvMemStorage* storage = cvCreateMemStorage(0);
// Detect faces and draw rectangle on them
CvSeq* faces = cvHaarDetectObjects(small_image, cascade, storage, 1.2f, 2, CV_HAAR_DO_CANNY_PRUNING, cvSize(20, 20), cvSize(100, 100));
cvReleaseImage(&small_image);
NSLog(@"found %d faces in image", faces->total);
// Create canvas to show the results
CGImageRef imageRef = originalImage.CGImage;
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
CGContextRef contextRef = CGBitmapContextCreate(NULL, originalImage.size.width, originalImage.size.height, 8, originalImage.size.width * 4,
colorSpace, kCGImageAlphaPremultipliedLast|kCGBitmapByteOrderDefault);
CGContextDrawImage(contextRef, CGRectMake(0, 45, originalImage.size.width, originalImage.size.height), imageRef);
CGContextSetLineWidth(contextRef, 4);
CGContextSetRGBStrokeColor(contextRef, 0.0, 0.0, 1.0, 0.5);
// Draw results on the iamge
for(int i = 0; i < faces->total; i++) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
// Calc the rect of faces
CvRect cvrect = *(CvRect*)cvGetSeqElem(faces, i);
CGRect face_rect = CGContextConvertRectToDeviceSpace(contextRef,
CGRectMake(cvrect.x * scale, cvrect.y * scale, cvrect.width * scale, cvrect.height * scale));
CGContextStrokeRect(contextRef, face_rect);
[pool release];
}
UIImage *returnImage = [UIImage imageWithCGImage:CGBitmapContextCreateImage(contextRef)];
CGContextRelease(contextRef);
CGColorSpaceRelease(colorSpace);
cvReleaseMemStorage(&storage);
cvReleaseHaarClassifierCascade(&cascade);
return returnImage;
}
```

Coming from Subversion I have used the "Mark For Comparison" and "Compare URLs" feature in TortoiseSVN. This gave me the ability to compare the development branch with the last release version to get a list of files that changed.
We use this list of files for final code review, documentation of the next version, etc.
As you can see it is possible to get a list of files and also be able to click each file to see a visual diff of the changes.
Is it possible to do something similar with Mercurial? The best I have found thus far is this command, however the list of files is far less useful than what I was able to get with Subversion.
`hg status --change {revisionnumber}`

i have a view, then in the view i have a scrollview and then in the scrollview i have a bunch of different objects. These objects aren't bigger than the scrollview's size, so i put a textView with a lot of text in the scrollview to see if it works but it is not scrolling. I deactivated the textview's scroll function. Does the scrollview knows the size of my textview? The textview's text is being set programmatically. Here's my view hierarchy: 
Thanks in advance.

Not sure how even that could be possible, but I have got this error message:
That happened after I've:
1. installed .NET 4 and Visual Studio 2010 Professional
2. installed VS 2010 SP1 package using WPI + NuGet + some groovy funky library packages
3. installed ASP.NET MVC 3 (includes April 2011 Tools Update) package using WPI
4. created a new empty MVC 3 C# Web Application with Razor support
5. failed to build it because got this error: Warning 3 The primary reference "System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".
6. checked if the project targets .NET 4. It does
7. removed the reference to System.Web.Mvc and tried to add it again (version 3.0) and got the aforementioned error message (screenshot above)
8. tried out re-installing some components, performed some of the previous steps in random order, spilled some virgin chicken's blood over my computer and restarted Windows again and again, all that to no avail.
I bet the solution is banal, but it must be that its Friday afternoon.
By the way, I have also VS 2008, MVC 1, MVC 2, all .NET framework versions installed and functional.
---
In fact, I have exactly the same problem with projects targeting .NET 4.
---
I feel that this is somehow related - I do really miss in the folder `C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0` (though is present)
I reinstalled .NET 4 framework but that didn't fix the problem.

This is a screenshot from Opera using FireFly. It clearly illustrates the padding (5px) and margin (0px) of the textbox. However, to the right of the textbox is an unidentified black space of approximately 10px that isn't HTML whitespace, `td` padding, textbox margin or anything else I can think of.
The spacing also exists in FireFox and IE 9.
(Please ignore the fact that the below button has the same indent - in its case I've added padding-right to the `td` as a hack to even it out)
Any ideas?

I'm having a problem getting the BlendState on the graphics device to work properly and display the alpha blending correctly.
In some cases you can see the leaves through other leaves, in other cases you cannot. And the trunk is also always obscured.
I've tried so many different combinations of setting up the BlendState. At the moment it looks like this:
```
GraphicsDevice.DepthStencilState = DepthStencilState.Default;
GraphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise;
//GraphicsDevice.BlendState = BlendState.AlphaBlend;
GraphicsDevice.BlendState = new BlendState()
{
AlphaBlendFunction = BlendFunction.Add,
AlphaDestinationBlend = Blend.InverseSourceAlpha,
AlphaSourceBlend = Blend.One,
BlendFactor = new Color(1.0F, 1.0F, 1.0F, 1.0F),
ColorBlendFunction = BlendFunction.Add,
ColorDestinationBlend = Blend.InverseSourceAlpha,
ColorSourceBlend = Blend.One,
ColorWriteChannels = ColorWriteChannels.All,
ColorWriteChannels1 = ColorWriteChannels.All,
ColorWriteChannels2 = ColorWriteChannels.All,
ColorWriteChannels3 = ColorWriteChannels.All,
MultiSampleMask = -1
};
```
The shader code are as follows:
float alpha = 1.0F;
if (HasAlphaTexture)
alpha = tex2D(AlphaSampler, IN.UV).xyz;
//...
//determine color values etc..
///...
return float4(result.xyz,alpha);
The maps I'm using for this looks like the following:

In a datagrid where one column is editable and the other columns are read only.
The non editable column is bound to a nullable decimal field in a collection and is initially NULL, so no value is present in the column.
When trying to click this cell to get the datagrid into edit mode, the click target is very small and hard to click.
How can you set the click target size for such a cell?

Is it possible to adjust the size/font of the TogglerBar, so that they are all equally large in case of different name size.
The example below is the solution proposed by Belisarius for : ["Can TogglerBar be used as multiple CheckBox in Mathematica ?"](https://stackoverflow.com/questions/6299215/can-togglerbar-be-used-as-multiple-checkbox-in-mathematica)
I would like each Button to be equally sized.
```
Manipulate[Graphics[
{
{White, Circle[{5, 5}, r]},(*For Mma 7 compatibility*)
If[MemberQ[whatToDisplay, "I am a Circle"],
{Red, Circle[{5, 5}, r]}],
If[MemberQ[whatToDisplay, "and I am a very nice Square"], {Blue,
Rectangle[{5, 5}, {r, r}]}],
If[MemberQ[whatToDisplay, "Other"], {Black,
Line[Tuples[{3, 4}, 2]]}]
},
PlotRange -> {{0, 20}, {0, 10}}

"and I am a very nice Square", "Other"},
ControlType -> TogglerBar,

```
: It is trully ugly in the code (if we can still call that a code) but looks good on display.

## Bah!
I have recently installed the MiniProfiler from [http://code.google.com/p/mvc-mini-profiler/](http://code.google.com/p/mvc-mini-profiler/) attempting to find all the slow calls on my site. (There are quite a few. But I've fixed a lot of it as a result of the profiler)
There were two common calls that I noticed were being reported by the profiler to take over a second to return in some cases. This didn't make any sense. The profiler showed the call (in mvc itself) to take around 2-4ms but the overall call took over 1 second. I spent quite a bit of time trying to narrow down the problem.
I noticed that the subsequent ajax calls are always instant but those were on delayed loads and the initial call times seemed to always grow from the initial page load so I decided to check in firebug and IE's firebug equivalent and the reported times are the same. I decided then to delay the calls made by the page by about 10ms using a `setTimeout()`. Suddenly the calls are exactly what they should be in terms of how long they take to complete. (Note the actual calls are instant but the reported times aren't)
I can not figure out why this is happening. I've tried to reproduce it using a new project and attempting to duplicate the behavior but alas, all is well in the new project. My initial thoughts were that the initial ajax calls were using the same connection due to the keep alive header, however, all the responses returned with "Closed" on the keep alive so I'm not sure that is the case.
## Here are the results from the different services

Take a look at [http://www.cssstickyfooter.com/](http://www.cssstickyfooter.com/) and resize your browser window to < 600px.
Notice how the header and footer elements fall short as the content overflows beyond their width.
Is there any way to prevent this from happening so that when the page scrolls horizontally, the header and footer don't fall short?

My layout is a fluid (98% of page width) containing box. I have multiple rows that take up 100% of the width of this container and have fixed height.
I need 3 divs (green, red, blue) in each row — but the red div is hidden until toggled on, at which point it slides out. Currently, when the red div slides out, depending on the amount of “Main Text” in the blue div, the blue div will wrap under the row.
## My goal
## Attempt 1
```
$('#a').click(function() {
$('#tC').animate({width: 'toggle'});
});
```

## Problems
The Main Text in the blue div is not wrapping. Instead of the text wrapping and the blue div always “filling in” the row, the blue div itself gets wrapped.
The “bottom text” in the blue div should stick to the bottom, whether the Main Text is a single line or two lines.
|
Can I prevent a floating div from wrapping when it's resized?

How do you change tab orders on the form when it is too complex like having splitters and again another splitter inside the first one and panels and activex controls and user controls and even some panels behind other panels to show/hide them based on the selection of a radio button,... I am attaching the picture also, for me it is even hard to visually find the control and select it especially when it is a panel under other panels...
so I took the route of overriding the and manually handling tabbing and works great. but I cannot imagine there is no way to handle this with IDE... maybe easier to change the resx files? any thoughts?

I am trying to integrate PrimeFaces 3.0 into my JSF 2.0 project. I've created some example code to try and get a PrimeFaces `<p:dataTable>` with a delete button/link in a column for each row. I want the delete action to trigger an Ajax refresh of the table (my current code triggers a render of the enclosing form using @form).
`<f:ajax>``<f:ajax>``<p:dataTable>`
If I implement this purely using core JSF elements (`<h:dataTable>`, `<h:commandButton>`, etc.) everything works as expected. Pardon the ugly output, but I'm not going to waste time on CSS styling for my example code.
Here is the code for the core JSF implementation page:
```
<h:form id="dataTableForm">
<f:ajax
listener="#{dataTableTestBean.processAjaxBehavior}"
event="action"
render="@form :messages :ajaxRenderTargetsInTemplate">
<h:panelGroup id="dataTablePanelGroup">
<h:commandLink
id="commandLinkAddRow"
value="Add Sample Row"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<h:commandButton
id="commandButtonAddRow"
value="Add Sample Row"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<sandbox:dataTableCC
id="dataTableCC"
valueList="#{dataTableTestBean.dataTableList}" />
</h:panelGroup>
</f:ajax>
<h:panelGroup rendered="#{empty dataTableTestBean.dataTableList}">
<h3>No Records To Display</h3>
</h:panelGroup>
<h:commandButton
id="commandButtonBackToStartPage"
value="#{bundle.backToStartPage}"
action="start"
immediate="true" />
</h:form>
```
Here is the code for the core JSF implementation CC:
```
<composite:implementation>
<h:dataTable
id="theDataTable"
rendered="#{not empty cc.attrs.valueList}"
value="#{cc.attrs.valueList}"
var="row"
emptyMessage="#{bundle.dataTableEmptyMessage}">
<f:facet name="header">#{bundle.dataTableHeader}</f:facet>
<h:column id="columnDeleteButton">
<h:commandLink
id="commandLinkDelete"
value="Delete"
action="#{dataTableTestBean.actionDeleteDataTableRow(row)}" />
</h:column>
<h:column>
<h:commandButton
alt="#{bundle.delete}"
image="#{resource['images/onebit_33_24x24.gif']}"
action="#{dataTableTestBean.actionDeleteDataTableRow(row)}" />
</h:column>
<h:column sortBy="#{row.name}">
<f:facet name="header">
#{bundle.columnHeaderName}
</f:facet>
<h:outputText value="#{row.name}" />
</h:column>
<h:column sortBy="#{row.rank}">
<f:facet name="header">
#{bundle.columnHeaderRank}
</f:facet>
<h:outputText value="#{row.rank}" />
<f:facet name="footer">
#{bundle.columnFooterRank}
</f:facet>
</h:column>
<h:column sortBy="#{row.serialNumber}">
<f:facet name="header">
#{bundle.columnHeaderSerialNumber}
</f:facet>
<h:outputText value="#{row.serialNumber}" />
<f:facet name="footer">
#{bundle.columnFooterSerialNumber}
</f:facet>
</h:column>
<f:facet name="footer">#{bundle.dataTableFooter}</f:facet>
</h:dataTable>
</composite:implementation>
```
The core JSF implementation will nicely fire the Ajax events and do the Partial Page Rendering, part of which is the render of an `<h:messages>` that confirms the event was processed successfully.
When I replace the `<h:dataTable>` with a `<p:dataTable>`, no problem. However, if I replace the `<h:commandButton>` and `<h:commandLink>` with `<p:commandButton>` and `<p:commandLink>`, the Ajax events are not making it to the `<f:ajax>` Ajax Group element. The record delete and insert operations do actually happen on the server, but the page is never refreshed. I will appear to the user that nothing happened. If you click the browser Refresh button, you will see that the operation did indeed happen. If you click the core JSF command button or command link, everything works. The PrimesFaces table renders and even the PrimeFaces "growl" popups are displayed as expected.
Here is a screenshot of the PrimeFaces implementation that has the problem. Again, pardon the ugliness of the buttons and links.
First, the page:
```
<p:growl id="growl" showSummary="false" showDetail="true" />
<h:form id="dataTableForm" styleClass="ui-widget">
<f:ajax
listener="#{dataTableTestBean.processAjaxBehavior}"
event="action"
render="@form :growl :ajaxRenderTargetsInTemplate">
<h:panelGroup id="dataTablePanelGroup">
<p:commandLink
id="pfCommandLinkAddRow"
value="Add Sample Row (pf)"
ajax="true"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<p:commandButton
id="pfCommandButtonAddRow"
value="Add Sample Row (pf)"
ajax="true"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<h:commandLink
id="hCommandLinkAddRow"
value="Add Sample Row (h)"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<h:commandButton
id="hCommandButtonAddRow"
value="Add Sample Row (h)"
actionListener="#{dataTableTestBean.handleAddDataTableRow}" />
<sandbox:primeFacesDataTableCC
id="dataTableCC"
valueList="#{dataTableTestBean.dataTableList}" />
</h:panelGroup>
</f:ajax>
<h:panelGroup rendered="#{empty dataTableTestBean.dataTableList}">
<h3>No Records To Display</h3>
</h:panelGroup>
<h:commandButton
id="commandButtonBackToStartPage"
value="#{bundle.backToStartPage}"
action="start"
immediate="true" />
</h:form>
```
and the CC:
```
<composite:implementation>

value="#{cc.attrs.valueList}"

this is a follow-up post of [Using pHash from .NET](https://stackoverflow.com/questions/6254447/using-phash-from-net)
How would you declare following C++ declaration in .NET?
```
int ph_dct_imagehash(const char* file,ulong64 &hash);
```
So far i have
```
[DllImport(@"pHash.dll")]
public static extern int ph_dct_imagehash(string file, ref ulong hash);
```
But I am now getting following error for
```
ulong hash1 = 0, hash2 = 0;
string firstImage = @"C:\Users\dance2die\Pictures\2011-01-23\177.JPG";
string secondImage = @"C:\Users\dance2die\Pictures\2011-01-23\176.JPG";
ph_dct_imagehash(firstImage, ref hash1);
ph_dct_imagehash(secondImage, ref hash2);
```
It basically says that my declartion of ph_dtc_imagehash is wrong.

I have a basic M:N setup with three tables: candidate, position, and candidate_position.
Here's a screenshot of the ERD from MySQL Workbench
Now, moving on from that let's talk about forms. In the default world of symfony generator, you'd have a separate CRUD interface for all three of these tables. However, I don't want to have a CRUD interface for `candidate_position`.
What I want, is for the create and edit actions of the Candidate interface to contain a multi-choice field (select list, checkbox array, whatever) that would create the CandidatePosition records as part of the Candidate actions.
On to the code
```
---

primary: true
unsigned: true
notnull: true
indexes:
fk_candidate_position_candidate1:

```
```
generator:

param:
model_class: Candidate
theme: admin
non_verbose_templates: true
with_show: false
singular: ~
plural: ~
route_prefix: candidate
with_doctrine_route: true
actions_base_class: sfActions
config:
actions: ~
fields:
first_name: { label: First Name }
last_name: { label: Last Name }
created_at: { label: Created On }
candidate_positions: {label: Positions}
list:
sort: [last_name, asc]
filter: ~
form:
display:
"User": [first_name, last_name]
"Applying For": [candidate_positions]
fields :
hide: [created_at]
edit: ~
new: ~
```
```
class candidateForm extends BasecandidateForm
{
public function configure()
{
unset( $this['created_at'] );
$this->widgetSchema['candidate_positions'] = new sfWidgetFormDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'renderer_class' => 'sfWidgetFormSelectCheckbox' )
);
$this->validatorSchema['candidate_positions'] = new sfValidatorDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'min' => 1 )
);
}
}
```
This all works, except when it comes to actually saving the data. This is the point where I get stuck.
I clearly need to do to create/edit/delete the CandidatePosition records, but I'm not sure where to start working. In `candidateActions`? Override `Basecandidate::save()`?
Let me know if there's any other data you might need to see.

My company doc pages need to be laid out as specified in [this image](https://i.stack.imgur.com/YkaSv.png):
The iframes are handled by the doc team software, MadCap Flare. The problem we're having is that we'd like the breadcrumbs and topic heading/logo to be fixed elements at the top of the page and have the topic content be scrollable, without disappearing under the fixed elements at the top.
We'd also like for the topic content scrollbar to be the web browser scrollbar, and not an overflow scroller. Additionally, because we have fixed elements at the top, we need to avoid content disappearing under the fixed element such as when the page loads or a link is clicked to an anchor somewhere on the page (anchors load at the top of the page and not the top of the content table cell).
The built content looks like this:
```
<body>
<table class="superheader">
<tr class="topRow">
<td class="headingBreadcrumbs">
<div class="breadcrumbs">breadcrumb trail</div>
<h1>topic heading</h1>
</td>
<td class="headingLogo">
<img src="logo.png">
</td>
</tr>
<tr class="contentRow">
<td class="content" colspan="2">topic content - full of tables, divs,
paragraphs, lists, etc...</td>
</tr>
</table>
</body>
```
I'm not married to the inner table. I'll welcome a different solution so long as:

In this example, the images are not loaded and I do not understand why?
I have always used these classes in which the images were loaded from the internet, but I also had problems with memory and I do not know too how to solve it. For example, when to scroll images I get exception - and after app crash. And I have no idea what to do. I understand what you need as a separate download of images over time and to remove non visible objects but I have found I need the algorithm.
For example - when i go to scrollDidScroll method i get all object when i not see them and remove image:
```
NSArray *views = [self subviews];
for (UIImageView *v in views) {
if(v.frame.origin.y >= self.contentOffset.y && v.frame.origin.y <= self.contentOffset.y + self.frame.size.height){
// If image of imageview is equal nil - call new operation
if(v.image == nil){
[self requestImageForIndexPath:[NSNumber numberWithInt:v.tag]];
}
else
{
v.image = nil;
}
}
}
```

I have a small project I am working on HTML5 canvas and I wanted to get some ideas how to accomplish it. I have built an outline of a tree using all the canvas line functions. lineTo, bezierCurveTo, quadracticCurve, etc. I have attached a picture of the outline. Now, what I would like to do is have some code that fills a percent of this outline. Kind of like a progress bar starting from the bottom. Does anyone have ideas on how to accomplish this?
Thanks

My question deals with this UI sample.
Having trouble with approach to managing the "selected" state of various UI view components. For example, I have menus above from which the user makes various selections. These selections should cause updates in the menus themselves (HL selected items) and also cause updates in the results, which would be based on the selections made. Also, the menus have different kinds of rules. For example, you can only have one "list" selected at a time, but you can have multiple "tags" selected.
One approach that I was thinking about was to create a Backbone model that holds the state of the UI "selection". For example, I could have a model SearchCriteria that holds this information. Then, when a user makes choices in the UI, I could update this model. I could have the various view components listen for changes in this model (as well as changes in the primary data models.) Then, the views would update their visual state by updating which items are shown as selected.
One item I am struggling with in this approach is who should be responsible for updating the selected state of an item. For example, on the list of tags, I might have the following pieces defined...
- - - -
Should I...
- - -
Sorry for so many questions. I am just having a hard time moving to this model of development.

I am using `jqGrid` with a horizontal scrollbar, but when I use the horizontal scrollbar the column header does not move together with the columns. Once I stop scrolling the grid comes back to normal. See the attached picture:
This is happening in FF (4.0.1) but not in IE8.
Here are the grid options I use:
```
width:'800',
shrinkToFit:false,
height: 500,
pager: '#pagerDiv',
gridview: true,
rowNum: 50,
rowTotal: 500,
sortorder: 'desc',
cellEdit: true,
cellsubmit: 'remote',
cellurl: 'MyURL',
beforeSaveCell:
function (rowid, cellname, value, iRow, iCol) {
return parse(value);
},
viewrecords: true,
loadComplete: loadCompleteHandler,
ignoreCase: true
....
jQuery(function(){
jQuery("#listTable").jqGrid('filterToolbar',{
stringResult: true,
searchOnEnter: false });
});
```
I have `jqGrid` version 3.8.2, `jQuery` 1.4.4 (full).
Is there any way to fix this?

I'm having a problem in IE9: . So even if i have the last radio input pressed, if i click anywhere within the wrapper, the radio will go back to the first one. As soon as i hover my mouse off the wrapper div the light blue color on the first radio input changes back to gray as it should be.
My page works as expected in FF, Chrome and IE-Compatability mode.
I tried creating a simple page with inputs and can't recreate the problem as it's happening in my large web page.
Any input into what can be causing this and/or how to stop it would be greatly appreciated.
```
<div id="wrapper">
...
<div id="region_sel_type">
<input type="radio" id="optLine" name="radio_region_sel_type" value="Line" /><label id="lblForOptLine" for="optLine" title="Line" unselectable="on"></label>
<input type="radio" id="optPoint" name="radio_region_sel_type" value="Point" /><label id="lblForOptPoint" for="optPoint" title="Point" unselectable="on"></label>
<input type="radio" id="optPolygon" name="radio_region_sel_type" value="Polygon" /><label id="lblForOptPolygon" for="optPolygon" title="Polygon" unselectable="on"></label>
<input type="radio" id="optList" name="radio_region_sel_type" value="List" /><label id="lblForOptList" for="optList" title="Input Coordinates" unselectable="on"></label>

</div>
...
</div>
```
Somewhere inside the 'wrapper' div i had a self-closing label IE9 did not support (even though they should)
```
<label id='x'/>

I posted recently regarding onbeforeunload implementation. Its working now but that only solved half of the problem. My application has lot of tabs and I want to throw this same confirmation to user if he clicks on a new tab without saving changes. all the tabs are div elements. How do you implement something of this sort?
Sample tab structure is attached, where every tab loads a new page.

I am seriously considering doing a Optical Character Recognition program. I am well versed with Java and would love to know about libraries available out there. Basically, I want to convert something like the following to text. I will need to give manual interruption to specify a pattern. For example, I would need to ask user to mark f in this text, so that I know where f occurs.
I am a newbie to this entirely, so I dont mind learning from scratch as well. Need guidance.

I had accidentally synthesized parentViewController
Edit/
This was working, and now it isn't, I don't think that I have done anything in code that would affect this behavior.
Here is what I am doing:
I have a view and associated view controller, called `NewAssetViewController`. NewAssetViewController's view has a mixture of `UITextField`s `and UITextView`s:
when I click on the `UITextView` I receive the delegate method `textViewShouldBeginEditing:`
in this method I present my customController view called `MultiPicker`:
```
[self presentModalViewController:multiPicker animated:YES];
```
if the user selects a button on this interface it either cancels, or returns selecting a value, I will only use the cancel case because it behaves the same way, and doesn't have any extra code.
multipicker's cancel method:
```
-(IBAction)cancel:(id)sender
{
//close returning nothing...
[delegate multiPickerDidCancel:self];
}
```
which calls `NewAssetController`'s `multiPickerDidCancel:` method:
```
-(void)multiPickerDidCancel:(MultiPicker *)aMultiPicker
{
[self dismissModalViewControllerAnimated:YES];
[aMultiPicker reset];
}
```
at this point now it freezes, doesn't crash, if I pause the debugger, this is what the trace looks like:

Now, I need to limit bandwith. I have 2 Virtual Machines running. One is just for fun. One is for important database access. I need to tell the "fun machine" to just use bandwith on network with less priority if the "database machine" is not using maximum of the bandwith.
I read [this](http://forums.virtualbox.org/viewtopic.php?f=1&t=40680)
But I am working on Windows.
Would be great if you have any suggestions.

Someone sent me a database (via means of an `.mdf` and `.ldf` file) which I attached on a server (with no errors, warnings, etc) and though I don't have proof (since I don't have access to the server the DB came from), it appears the primary key (identity) values are different from what they were originally. Also, they appear to be "reset" - all primary key values are starting at 1, whereas based on foreign key references it is clear that is incorrect (for example, a table with only 1 row has a primary key value of 1, but a table that references it references a value of 7).
Though I don't really care, I am curious as to why this is happening (if there is an explanation)?
What I really need is to figure out if there is a way to attach the database and retain the proper values?
As far as I can tell, the foreign key references are set up properly.
Here are some screenshots:

I'm creating an HTML file containing a table with alternating row colors. One of the columns in this table is a set of cells containing sub-tables. My problem is that I can't get the sub-tables to have the same background color as the row in which they're a member. I've tried having a CSS class with
```
background-color: transparent;
```
but that doesn't seem to change anything at all.
It might be easier to understand the problem with a visual. I fuzzed-out the text and circled the sub-tables to highlight them. Basically, I need those white areas within the rows with a gray background to also have gray backgrounds (for their entire table) so you can't really tell it's a separate table.
Also, this has to work in IE. I know, I know, but...that's how it is.
Thanks!

Consider a `div` with the `border-radius`, `border`, and `background-color` CSS attributes applied:
```
<div style="background-color:#EEEEEE; border-radius:10px; border: 1px black solid;">
Blah
</div>
```
Now consider a similar layout but with the `background-color` specified in an inner-div:
```
<div style="border-radius:10px; border: 1px black solid;">
<div style="background-color:#EEEEEE;">
Blah
</div>
</div>
```
I'm dismayed by the fact that the `background-color` of the `<div>` is obscuring the border of the `<div>`.
This is a simplified sample of the problem. In reality, I'm using a `<table>` as the inner element with alternating row colors. And I'm using a `<div>` as the outer element since `border-radius` does not seem to work on the `<table>` element. [Here's a jsfiddle](http://jsfiddle.net/jpNy7/9/) of a sample of this problem.
Does anyone have a suggestion for a solution?

I'm using an AdvancedDataGrid in ActionScript 3/Flex 4. The grid has 5 columns: Caller Intent, Labels, Strategy, Confirmation Mode, and Confirmation Promptlet. All columns are editable except for Labels. However, if you change the Confirmation Mode value to NEVER, the next column Confirmation Promptlet becomes uneditable and is set with the value 'n/a' (this is the desired functionality).
Unfortunately, the image is not clear. In the second row, I changed the Confirmation Mode value to NEVER. This is what happens when I start tabbing out of the Confirmation Mode cell:
1st Tab: Confirmation Promptlet populated with 'n/a'. I don't see anything in focus.
2nd Tab: The 5th tab from the left in the view stack (dark grey) is in focus.
3rd Tab: I don't see anything in focus.
4th Tab: The button with the green '+' (top left) is in focus.
5th Tab: The grid itself is in focus.
6th Tab: Finally I get to the Caller Intent cell of the next row (when this image was captured)
I tried setting tabEnabled="false" and tabFocusEnabled="false" for the button. I set only tabFocusEnabled="false" for the AdvancedDataGrid. But then the Tab focus starts moving to the components in the upper right panel and lower right panel.
I need to accomplish 2 things:
1. Have tabbing be contained in the grid, in the upper right panel, and in the lower right panel. Meaning tabbing should not cross from one area to another.
2. Have an uneditable field not mess up the normal tabbing behaviour.

I am throwing an exception in a Silverlight enabled service and catching it in my silverlight client. I have done everything as per the manual, but still getting what I think is unexpected behavior.
Code from Client
```
try
{
client.ThrowFaultExceptionCompleted += (s, args) =>
{
DoCallback(args);
};
client.ThrowFaultExceptionAsync(new ThrowFaultExceptionRequest());
}
catch (FaultException<MyFaultException> myFex)
{
}
catch (FaultException fex)
{
}
```
Here is the code from the service
My Custom Fault Exception class
```
[DataContract]
public class MyFaultException
{
private string _reason;
private string _myExceptionStackTrace;
[DataMember]
public string Reason
{
get { return _reason; }
set { _reason = value; }
}
[DataMember]
public string MyExceptionStackTrace
{
get { return _myExceptionStackTrace; }
set { _myExceptionStackTrace = value; }
}
}
```
The bit of service side code that throws the fault exception. For testing purposes I am calling this method from the client.
```
[OperationContract]
[FaultContract(typeof(MyFaultException))]
public void ThrowFaultException()
{
MyFaultException mfex = new MyFaultException();
mfex.Reason = "No Reason!";
mfex.MyExceptionStackTrace = "Long stack trace here";
System.ServiceModel.Web.WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
//throw new FaultException<MyFaultException>(mfex ,new FaultReason(new FaultReasonText("My Fault Reason Text here!")), new FaultCode("my fault code here"));
throw new FaultException<MyFaultException>(mfex);
}
```
no matter if I throw the FaultException with a single param or those three params in the commented line I get an error in my Reference.cs file in the silverlight proxy class like the one below
and it doesnt ever go to either of the catch blocks.. Is this normal behavior? I have to now catch the error in the callback method DoCallback(args) and in that method check for (args.Error == null). Why doesnt the catch block get hit?
Thanks for your time...

Can anyone explain the weird presentation behavior in the UI screenshot above? As you can see, there's an undesirable separation between the insurance type and the top of the row. When looking at the code via Firebug, there's a clear break in the code. You can view this oddity in the code screenshot below.
The div.insurance-type parent container has no CSS styles. In other words, the vertical-align property, the margin-top property, the padding-top property, and the float property are set to default values and don't inherit a value that might cause this presentation. The children divs have this style:
```
div#worklist table tr td.col-InsuranceType div.insurance-type div {
display: block;
margin-bottom: 2px;
margin-left: 25px;
}
```
The span.insurance-company has this style:
```
div#worklist table tr td.col-InsuranceType div.insurance-type span.insurance-company {
font-weight: bold;
}
```
The components of this web app are:
- - - - -
This issue occurs in FF4, IE8 and IE7. Please let me know if you know the root cause of this unexplainable presentation behavior.
Thanks.

I've read you may change it using the fifth parameter of PHP mail(), although I'm not using that. Is there a way to change this using PHPMailer? Thanks!

I have a tableview with a segmentedControl in the header, i want the segment control to change the data depending on which segment is clicked, in this case Upcoming/Weekly.
Both data sources come from an XML file on my server, which is the part im having trouble with, as im still new to using NSXMLParser
ive messed around with some code, but to no avail. I know that my segmentAction is being picked up because ive used logs to do so. attached is code and an image of my table, cheers

I have 2 or 3 hough lines drawn on the edges of the road these lines intersect at the horizon point where the road and the sky meet. I want to find and plot this point. How can i achieve this using hough lines?
An idea rings in my mind of voting map how can i create voting map ?
This is my code. Assume hough lines from the edges of the road, intersect and make a triangle with the road area inside.
here is my output image
```
I = imread('1.jpg');
J = imfilter(I, fspecial('gaussian', [17 17], 5), 'symmetric');
se3 = strel('disk', 4);
%J = imdilate(J, se);
J = rgb2gray(J);
BW = edge(J, 'sobel');
BW = imdilate(BW, se3);
[H T R] = hough(BW);
P = houghpeaks(H, 4);
lines = houghlines(J, T, R,P);
Q = figure(5);
imshow(I)
hold on;
xy1 = [lines(3).point1; lines(3).point2];
line1 = plot(xy1(:,1),xy1(:,2),'LineWidth',6,'Color','blue');
xy2 = [lines(4).point1; lines(4).point2];
line2 = plot(xy2(:,1),xy2(:,2),'LineWidth',6,'Color','blue');
xy3 = [lines(2).point1; lines(2).point2];
line3 = plot(xy3(:,1),xy3(:,2),'LineWidth',6,'Color','blue');
```

I'm using SVN within Eclipse. Whenever I change a file I commit the changes. It works for everything except for three certain folders (which contain certain files) I cannot commit. When trying to commit them I receive the following error message:
`workspace\yp\src\yp\forum\locale\cs` is one of the three uncommitable folders. The folder definitely doesn't exist on the server yet, but I get the above error each time I'm trying to upload it.
How do I solve the problem?
I've deleted the `.svn` folders from the problematic directories. I still get the same error when trying to commit and the problematic directories have no `.svn` folders.
I'm still trying to fix the problem. Now I get another error message when trying to commit:
Now I've tried to do `Team --> Cleanup` and got that error message:

I want to create this infographic( Teaser ;) ) on [http://www.bcndevcon.org](http://www.bcndevcon.org) website
The problem:
If I use I won't be able to display any information on iOS devices BUT i will be able to perform animations if I want to feed in in realtime.
If I use I won't be able to display it on any IE, and animations will be slow...
Finally I'm not really sure is a great solution so...
Any suggestion!?

Ok guys, this is driving me nuts. I got the following (odata) entity which represents a page structure in which every page can have any children and any parents. (basically a graph in which all nodes could be connected). In the database it's represented by a many-to-many relationship with two tables `Page <-> PagePage <-> Page`.
The problem is, I'm just not able to insert a new entity including a relation. The last thing I tried was:
```
Page page = new Page()
{
Id = Guid.NewGuid(),
Title = "New Page",
Created = DateTime.Now,
LastChanged = DateTime.Now,
IsRedirected = false,
Position = 0,
Html = "Add your HTML here.",
Parent = { parent }
};
this.Context.AddToPages(page);
this.Context.AddLink(parent, "Children", page);
parent.Children.Add(page);
this.Context.SaveChanges();
```
I can't think of anything else to try. Has anyone cracked this one?

I'm currently writing a pure GWT (2.3) application and I require the use of a dialog box. I followed the examples in the documentation and they work as they should.
My requirement is to display a dialog displaying some text in a scrollable text area with a close button (for now). The problem is that the right side of my dialog panel is being clipped off (please correct me if my terminology is incorrect here). Rather than explain it more, I will include some sample code and the resultant dialog box.
```
// This next block just builds debug text to display
StringBuilder sb = new StringBuilder();
for (int i = 0 ; i < 100; i++) {
sb.append(((i+1) < 10) ? " " : "").append(i+1).append(" : ");
for (int j = 0; j < 8; j++) {
sb.append("1234567890");
}
sb.append("\n");
}
final DialogBox dialogBox = new DialogBox();
dialogBox.setGlassEnabled(true);
dialogBox.setAnimationEnabled(true);
dialogBox.setText("My broken dialog box");
VerticalPanel contentPanel = new VerticalPanel();
contentPanel.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
contentPanel.setSpacing(4);
TextArea ta = new TextArea();
ta.setCharacterWidth(90);
ta.setVisibleLines(40);
ta.setReadOnly(true);
ta.setText(sb.toString());
contentPanel.add(ta);
Button closeButton = new Button("Close Button");
closeButton.addClickHandler(new ClickHandler() {public void onClick(ClickEvent event) {dialogBox.hide();}});
contentPanel.add(closeButton);
dialogBox.setWidget(contentPanel);
dialogBox.show();
```
Maybe I'm doing something fundamentally wrong in my layout code? Any help much appreciated.

I'm trying to access information within a `Graph` object in Mathematica 8. For some reason, the `Part` command does not seem to work.
`myGraph` is the object I want to gain access to.
The first line below displays myGraph. The others serve to inspect it.
```
myGraph
myGraph // FullForm
myGraph // InputForm
myGraph // OutputForm
myGraph[[1]]
myGraph[[2]]
```
Why doesn't `myGraph[[1]]` return `List[1,3,4,2,5]` ?
[I checked to level 2 just in case `Graph` were wrapped by some invisible wrapper. `Level[myGraph,1]`, simply returns `{}`. And `FullForm[myGraph][[1]]` returns a picture of the graph itself.
I must be overlooking something obvious.
---
Here's the code I used to produce the graph. Most of it is irrelevant to the issue at hand.
But at least you'll be working with the same code I am using.
```
ClearAll[edges, compatibleQ, adjacentCourses, g];
edges[w_, b_] :=
Most /@ Accumulate /@
Flatten[Permutations[#] & /@ IntegerPartitions[w, All, b], 1]
compatibleQ[j_, k_, edg_] :=
If[Intersection[edg[[j]], edg[[k]]] == {}, {j, k}, False]
adjacentCourses[edg_] :=
Module[{len = Length[edg]},
Cases[Flatten[Table[compatibleQ[j, k, edg], {j, len}, {k, j, len}],
1], {v_, w_} :> v \[UndirectedEdge] w]]
myGraph = Graph[adjacentCourses[edges[9, {2, 3}]], VertexLabels -> "Name",
ImagePadding -> 10]
```

How can I programmatically access information about a 'Graph` object in Mathematica 8?

I'm using this code snippet to encrypt/decrypt data in my app's database:
[http://www.androidsnippets.com/encryptdecrypt-strings](http://www.androidsnippets.com/encryptdecrypt-strings)
It appears that the javax.crypto.KeyGenerator.generateKey() operation works differently in Android 2.3.3 OS than in other (previous?) versions. Naturally, this presents a major problem for my users when they upgrade their device from 2.2 to 2.3.3 and the app starts throwing errors decrypting the database.
Is this a known issue? Am I using the crypto library incorrectly? Anyone have any suggestions on how to address this so that data encrypted in 2.2 is able to be decrypted in 2.3.3?
I built a test app that feeds values through the encrypt function. When I run it on a 2.2 AVD, I get one result. When I run it on a 2.3.3 AVD, I get a different result.

I have written this trivial action method associated to a textfield.
Every time I enter text into a textfield a search in a PDF is performed and `PDFView` automatically scroll to selection:
```
- (IBAction) search:(id)id
{
NSString *query = [self.searchView stringValue]; // get from textfield
selection = [document findString: query fromSelection:NULL withOptions:NSCaseInsensitiveSearch];
if (selection != nil)
{
[self.pdfView setCurrentSelection:selection];
[self.pdfView scrollSelectionToVisible:self.searchView];
}
}
```
Problem is that after 3 or 4 searches I get `EXC_BAD_ACCESS` on row (i).
If I debug I see that query contains an `NSCFString` and not an `NSString`.
I think it is a memory management problem..but where?
I replicated the same issue inside a trivial testcase:
```
@interface PDFRef_protoTests : SenTestCase {
@private
PDFDocument *document;
}
........
- (void)setUp
{
[super setUp];
document = [[PDFDocument alloc] initWithURL: @"a local url ..."];
}
- (void)test_exc_bad_access_in_pdfdocument
{
for (int i =0 ;i<100; i++)
{
NSString *temp;
if (i % 2 == 0) temp = @"home";
else if (i % 3 ==0) temp = @"cocoa";
else temp=@"apple";
PDFSelection *selection = [document findString: temp
fromSelection:nil
withOptions:NSCaseInsensitiveSearch];
NSLog(@"Find=%@, iteration=%d", selection, i);
}
}
```
:
1) It seems that it happens also if I use asynchronous search (method beginFindString: withOptions) every time I perform second search.
2) I found a similar problem to mine in MacRuby Issue Tracking: [http://www.macruby.org/trac/ticket/1029](http://www.macruby.org/trac/ticket/1029)
3) It seems that if I disable temporarily garbage collection it works but memory goes up.
I wrote something like:
```
[[NSGarbageCollector defaultCollector] disable];
[[NSGarbageCollector defaultCollector] enable];
```
surrounding search code
Very weird thing is that sometimes all works. Than I clean and Rebuild and problem arises again. From a certain point of view is is not 100% reproducible. I suspect a bug in PDFKit or some compiler setting I have to do
Dears it seems very crazy. I'd concentrate on testcase which is very trivial and which replicates easily the problem. What's wrong with it? This testcase works only if I disable (by code or by project setting) GC
Boys it seems a bug but I downloaded an example called PDFLinker from Apple website ([http://developer.apple.com/library/mac/#samplecode/PDFKitLinker2/Introduction/Intro.html#//apple_ref/doc/uid/DTS10003594](http://developer.apple.com/library/mac/#samplecode/PDFKitLinker2/Introduction/Intro.html#//apple_ref/doc/uid/DTS10003594)). This example implements a PDFViewer. Code of my app and this example are quite similars. For the same search action on same PDF, my memory rises at 300/400 MB while PDFLinker rises at 190MB. Clearly there is something wrong in my code. But I am comparing it bit by bit and I don't think I am inserting memory leaks (and Instrument doesn't give me any evidence). Maybe is there some project-wide setting ?
Changing from 64 bit to 32 bit memory consumption lowered. Surely there is a problem with 64bit and PDFKit. BTW still EXC_BAD_ACCESS on second search
Crucial point is that PDFKit with Garbage collection is bugged.
If I disable GC all works correctly.
I had another issue that had complicated my analysis: I disabled GC on Project Setting but GC remained enabled on Target Settings. So Apple's example PDFLinked2 worked while mine not.

I'm designing my application UI. I need a layout looks like this:
(< and > are Buttons). The problem is, I don't know how to make sure the TextView will fill the remaining space, with two buttons have fixed size.
If I use fill_parent for Text View, the second button (>) can't be shown.
How can I craft a layout that looks like the image?

While trying to optimize a code, I'm a bit puzzled by differences in profiles produced by `kcachegrdind` and `gprof`. Specifically, if I use gprof (compiling with the `-pg` switch, etc), I have this:
```
Flat profile:
Each sample counts as 0.01 seconds.
% cumulative self self total
time seconds seconds calls ms/call ms/call name
89.62 3.71 3.71 204626 0.02 0.02 objR<true>::R_impl(std::vector<coords_t, std::allocator<coords_t> > const&, std::vector<unsigned long, std::allocator<unsigned long> > const&) const
5.56 3.94 0.23 18018180 0.00 0.00 W2(coords_t const&, coords_t const&)
3.87 4.10 0.16 200202 0.00 0.00 build_matrix(std::vector<coords_t, std::allocator<coords_t> > const&)
0.24 4.11 0.01 400406 0.00 0.00 std::vector<double, std::allocator<double> >::vector(std::vector<double, std::allocator<double> > const&)

```
Which seems to suggest that I need not bother looking anywhere but `::R_impl(...)`
At the same time, if I compile without the `-pg` switch and run `valgrind --tool=callgrind ./a.out` instead, I have something rather different: here's a screenshot of the `kcachegrind` output
If I interpret this correctly, it seems to suggest that `::R_impl(...)` only takes about 50% of time, while the other half is spent in linear algebra (`Wrat(...)`, `eigenvalues` and the underlying lapack calls ) which was way down below in the `gprof` profile.
I understand that `gprof` and `cachegrind` use different techniques, and I'd not bother if their results were somewhat different. But here, it looks very different, and I'm at loss as to how to interpret those. Any ideas or suggestions?

I am looking for advice or examples of how to create a timetable widget as shown in the image below;
I need the user to be able to the rectangles to or them up and down each column of the timetable.
It's quite simple when you look at it but I imagine the JavaScript involved is quite tricky and I just don't know where to start.
I'm thinking of using a table and overlaying div's but that's about as far as I've got.

I want to know how to read the traffic information from google map as here in the following image. Google only displays the traffic layer by red, green, and yellow lines. But how can an application identify the color and find out how much traffic there is between source and destination.
Visually users can see with their eyes and identify the colors but what about the application?

This question is very similar to that posed [here](https://stackoverflow.com/questions/3273880/perlin-noise-detail-level-how-to-zoom-in-on-a-landscape).
My problem is that I have a map, something like this:
[](https://i.stack.imgur.com/9ACDe.jpg)
This map is made using 2D Perlin noise, and then running through the created heightmap assigning types and color values to each element in the terrain based on the height or the slope of the corresponding element, so pretty standard. The map array is two dimensional and the exact dimensions of the screen size (pixel-per-pixel), so at 1200 by 800 generation takes about 2 seconds on my rig.
Now zooming in on the highlighted rectangle:
Obviously with increased size comes lost detail. And herein lies the problem. I want to create additional detail on the fly, and then write it to disk as the player moves around (the player would simply be a dot restricted to movement along the grid). I see two approaches for doing this, and the first one that came to mind I quickly implemented:
This is a zoomed-in view of a new biased local terrain created from a sampled element of the old terrain, which is highlighted by the yellow grid space (to the left of center) in the previous image. However this system would require a great deal of modification, as, for example, if you move one unit left and up of the yellow grid space, onto the beach tile, the terrain changes completely:
So for that to work properly you'd need to do an excessive amount of, I guess the word would be interpolation, to create a smooth transition as the player moved the 40 or so grid-spaces in the local world required to reach the next tile over in the over world. That seems complicated and very inelegant.
The second approach would be to break up the grid of the original map into smaller bits, maybe dividing each square by 4? I haven't implemented this and I'm not sure how I would in a way that would actually increase detail, but I think that would probably end up being the best solution.
Any ideas on how I could approach this? Keep in mind it has to be local and on-the-fly. Just increasing the resolution of the map is something I want to avoid at all costs.

After realizing why Eclipse did not want to open XMl files in its Layout designer, I hope we'll be able to solve this issue here.
Anyway, after I create the project in InteliJ IDEA, exports it in Eclipse format, opens it in Eclipse, I realize that Eclipse Layout Designer does not recognize such XML file and the Layout Designer cannot load its content into right pane of the designer. This is how the Designer looks like after I try to load InteliJ-created XML file.
Indeed, I can load Android layout elements after setting Designer to correct Android OS version (dropdown list, elements appear in left pane of the designer), but the very content of the XML file gets never loaded in the right pane of the Designer.
After examining the STRUCTURE of a project created in Eclipse and a project created in IntelliJ, I realized that Eclipse DOES NOT generate Java files in /gen directory nor it imports correct Android library once I import IntelliJ-created project. Look at the image.
The upper project is created in Eclipse and it has both Android R files and Android library imported.
The project below is created in IntelliJ, exported to Eclipse format and then imported into Eclipse workspace. It does not have either Android R files or Android library imported.
Another problem is that I cannot force rebuild the Intellij-created project or even clean it in Eclipse because it isn't in the list of projects. Like Eclipse does not see it as an Android project at all.
The final issue is: when I manually set Android OS version in Layout Designer, then try to grab&drop Android element into the right pane of the Designer, I get the message (error) "Missing project resources". Look at the image.
Please help!

I am trying to write a strategy game using XNA 4.0, with a dynamically generating map, and it's really difficult to create all the ground textures, having to distort them individually in photoshop.
So what I want to do is create a flat image, and then apply the distortion programatically to simulate perspective, by moving the corners of the image.
Here is an example done in photoshop:

I'm completely new to Linux and have been trying to get my (Windows built) Java Swing projects to work correctly on XUbuntu on a separate machine from executable jar files I built.
I've reduced the problem to a minimum amount of code
```
import java.awt.Dimension;
import javax.swing.*;
public class JFrameTest extends JFrame {
public JFrameTest(String title) {
super(title);
JLabel lab = new JLabel("Label");
this.getContentPane().add(lab);
this.setMinimumSize(new Dimension(200, 200));
this.pack();
this.setVisible(true);
}
public static void main(String args[]) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JFrameTest frame = new JFrameTest("Title");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
```
On Windows I see:
In Xubuntu I just see a grey box and the label, not the Title or close icons etc. I also have to kill (-9) the jvm after I've ctrl zedded from the command line. I launched it with java -jar filename.jar
My Linux machine is running Xubuntu 11. I've installed the sun Java 6_24 JRE. I Googled for this and found something similar relating to Compziz(?) but this was allegedly fixed a while back. I'm a bit stuck now. I have got one Swing app that works OK in that it responds to buttons OK but still doesn't show the Title etc. Any help would be much appreciated.

[Having the application minimize to the system tray when button is clicked?](https://stackoverflow.com/questions/1297028/having-the-application-minimize-to-the-system-tray-when-button-is-clicked). The first time I minimize it, it's nowhere to be found on the screen - taskbar/above taskbar/tray.
If i hit alt tab, I can see my app there; if I alt tab into it and minimize it again, it shows up above the taskbar:

I have a simple requirement: The number of columns of my `<tr:table/>` is dynamic. I will have a list of objects, `someBean.features` which will determine how many columns are rendered.
The following diagram should clarify my requirement.
In the code that I was given, there was usage of the JSTL `<c:forEach/>` tag which obviously created problems when used in a JSF environment. They had done something like this:
```
<tr:table value="#{someBean.values}">
<tr:column headerText="Name">
<tr:outputText value="#{someBean.name}"/>
</tr:column>
<c:forEach var="col" items="#{someBean.features}">
<tr:column headerText="Column-#{col.id}">
<tr:outputText value="#{col.name}"/>
</tr:column>
</c:forEach>
</tr:table>
```
But when I profiled the above code, the method `someBean.getValues` which is the input to the `<tr:table/>` tag above was getting called several thousands of times rather than about 20. This - as I figured out - was due to the fact that `<c:forEach/>` tag is a compile time tag where as `<tr:*/>` are render time tags.
So, here's what I intend to do (replace `<c:forEach/>` with `<tr:iterator/>`:
```
<tr:table value="#{someBean.values}">
<tr:column headerText="Name">
<tr:outputText value="#{someBean.name}"/>
</tr:column>
<tr:iterator var="col" value="#{someBean.features}">
<tr:column headerText="Column-#{col.id}">
<tr:outputText value="#{col.name}"/>
</tr:column>
</tr:iterator>
</tr:table>
```
But, for some reason, the `<tr:iterator/>` doesn't seem to like being placed inside a `<tr:table/>` and it never gets executed.
Any solution, tips, guidelines will be greatly appreciated.
Oh and we're using JSF 1.1 with a MyFaces Trinidad 1.0.13 implementation.
Thanks.

Given that `g` is a graphics object with primitives such as `Line`s and `Polygon`s, how do you remove some of them? To add more primitives to an existing graphics object we can use `Show`, for instance: `Show[g, g2]` where `g2` is another graphics object with other primitives. But how do you remove unwanted primitive objects? Take a look at the following
```
ListPlot3D[{{0, 0, 1}, {1, 0, 0}, {0, 1, 0}, {1, 1, 0}}, Mesh -> {1, 1}]
```
Now, for the input form:
```
InputForm[
ListPlot3D[{{0, 0, 1}, {1, 0, 0}, {0, 1, 0}, {1, 1, 0}}, Mesh -> {1, 1}]
]
```
To create a wire frame from this object all we have to do is remove the polygons. As an extra we can also remove the vertex normals since they don't contribute to the wireframe.
Notice that to make a wireframe we can simply set `PlotStyle -> None` as an option in `ListPlot3D`. This gets rid of the `Polygon`s but doesn't remove the `VertexNormals`.
To clarify the question. Given that
```
g = ListPlot3D[{{0, 0, 1}, {1, 0, 0}, {0, 1, 0}, {1, 1, 0}}, Mesh -> {1, 1}]
```
How do you remove some of the of the graphics primitives from `g` and how do you remove some of the options, i.e. `VertexNormals`? Note: option `VertexNormals` is an option of `GraphicsComplex`.
If this is not possible then maybe the next question would be, how do you obtain the data used to generate `g` to generate a new graphics object with some of the data obtained from `g`.

Say I have this HTML:
```
<div>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
</div>
```
I want to determine what line in the client's browser the phrase `sed do eiusmod tempor` is on and from there determine where that line starts and ends. Is there any way to do this with javascript.
What I am trying to do with that line then is to put a border along the bottom and the sides (so a border on each side of that text that is parallel to the sides of the area that that `<div>` is located in.).
I know if there is a solution it won't be easy, but I am willing even if it is relatively difficult. Also, I am using jQuery if it has a method to do this.
Also, if there is a way with CSS I would be even happier.
Here is approximately talking about, the highlighted part is the text I am looking for and the red line is supposed to represent what has a border set on it.
