I'm looking for a GIS/Geometric algorithm:
I have 1000 points randomly distributed in a large area(such as a city), How can I find out all the small areas which have more than 15 points? Like this picture below:
Each point has its own latitude and longitude coordinates. The small area less than 200m x 200m.

I'm stuck trying to update a progressbar from other threads ran in a different class. To explain what I do I think a picture will be better. I want to update the progressbar in the //HERE point :
I've tried using a delegate, tried with ReportProgress and I think i've basically tried to use everything google reported in the first 100 results, without success. I'm still learning WPF and this might be silly way to proceed, i'm looking for a quick and dirty way to get the work done but feel free to tell me what I should redesign for a cleaner application.
: More code.
In ExecutorWindow.xaml.cs :
```
public void RunExecutor()
{
// CREATE BACKGROUNDWORKER FOR EXECUTOR
execBackground.DoWork += new DoWorkEventHandler(execBackground_DoWork);
execBackground.RunWorkerCompleted += new RunWorkerCompletedEventHandler(execBackground_RunWorkerCompleted);
execBackground.ProgressChanged += new ProgressChangedEventHandler(execBackground_ProgressChanged);
execBackground.WorkerReportsProgress = true;
execBackground.WorkerSupportsCancellation = true;
// RUN BACKGROUNDWORKER
execBackground.RunWorkerAsync();
}
private void execBackground_DoWork(object sender, DoWorkEventArgs e)
{
myExecutor = new Executor(arg1, arg2);
myExecutor.Run();
}
private void execBackground_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
MessageBox.Show("RunWorkerCompleted execBackground");
}
private void execBackground_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
ExecutorProgressBar.Value += 1;
}
// TESTING
private void updateProgressBar(int i)
{
ExecutorProgressBar.Value += i;
}
public delegate void callback_updateProgressBar(int i);
```
In Executor.cs :
```
public void Run()
{
string[] options = new string[2];
int i = 0;
while (LeftToRun > 0)
{
if (CurrentRunningThreads < MaxThreadsRunning)
{
BackgroundWorker myThread = new BackgroundWorker();
myThread.DoWork += new DoWorkEventHandler(backgroundWorkerRemoteProcess_DoWork);
myThread.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorkerRemoteProcess_RunWorkerCompleted);
myThread.ProgressChanged += new ProgressChangedEventHandler(backgroundWorkerRemoteProcess_ProgressChanged);
myThread.WorkerReportsProgress = true;
myThread.WorkerSupportsCancellation = true;
myThread.RunWorkerAsync(new string[2] {opt1, opt2});
// HERE ?
CurrentRunningThreads++;
i++;
LeftToRun--;
}
}
while (CurrentRunningThreads > 0) { }
logfile.Close();
MessageBox.Show("All Tasks finished");
}
private void backgroundWorkerRemoteProcess_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker myBackgroundWorker = sender as BackgroundWorker;
string[] options = (string[])e.Argument;
string machine = options[0];
string script = options[1];
// UPDATE HERE PROGRESSBAR ?
RemoteProcess myRemoteProcess = new RemoteProcess(machine, script);
string output = myRemoteProcess.TrueExec();
// UPDATE HERE PROGRESSBAR ?
this.logfile.WriteLine(output);
}
private void backgroundWorkerRemoteProcess_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
CurrentRunningThreads--;
}
private void backgroundWorkerRemoteProcess_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
//myExecWindow.ExecutorProgressBar.Value = e.ProgressPercentage; // TESTING
//ExecutorWindow.callback_updateProgressBar(1); // TESTING
}
```
: I got it! Simple in fact, but i guess I've been looking too close to find out.
In my ExecutorWindow class :
```
private void execBackground_DoWork(object sender, DoWorkEventArgs e)
{
myExecutor = new Executor(arg1, arg2);
myExecutor.Run(sender);
}
private void execBackground_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
ExecutorProgressBar.Value += 1;
}
```
And in my Executor class :
```
private BackgroundWorker myExecutorWindow;
[...]
public void Run(object sender)
{
myExecutorWindow = sender as BackgroundWorker;
string[] options = new string[2];
int i = 0;
while (LeftToRun > 0)
{
if (CurrentRunningThreads < MaxThreadsRunning)
{
BackgroundWorker myThread = new BackgroundWorker();
myThread.DoWork += new DoWorkEventHandler(backgroundWorkerRemoteProcess_DoWork);
myThread.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorkerRemoteProcess_RunWorkerCompleted);
myThread.ProgressChanged += new ProgressChangedEventHandler(backgroundWorkerRemoteProcess_ProgressChanged);
myThread.WorkerReportsProgress = true;
myThread.WorkerSupportsCancellation = true;
myThread.RunWorkerAsync(new string[2] {opt1, opt2});
CurrentRunningThreads++;
i++;
LeftToRun--;
}
}
[...]
private void backgroundWorkerRemoteProcess_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker myBackgroundWorker = sender as BackgroundWorker;
myBackgroundWorker.ReportProgress(1);
// PROCESSING MY STUFF HERE
myBackgroundWorker.ReportProgress(1);
}
private void backgroundWorkerRemoteProcess_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
myExecutorWindow.ReportProgress(1);
}
```
Thank you !

I'm customizing a TFS Work Item Type, adding a 'Business Description' HTML Field, but I cannot get the Layout right:
```
<Tab Label="Details">
<Group>
<Column PercentWidth="60">
<Control FieldName="Customer.BusinessDescription" Type="HtmlFieldControl" Label="Business Description:" LabelPosition="Top" Dock="Fill" />
</Column>
<Column PercentWidth="40">
<Control FieldName="Microsoft.VSTS.CMMI.Symptom" Type="HtmlFieldControl" Label="Symptom:" LabelPosition="Top" />
<Control FieldName="System.History" Type="WorkItemLogControl" Label="&History:" LabelPosition="Top" />
</Column>
</Group>
</Tab>
```
This turns out like this:
While I really want this ('Photoshopped' with MSPaint):
I have played around with the Fill properties on all three fields, have already set the MinimumSize property on the BusinessDescription field, added a group inside the left column, but I do not seem to find a solution for this.
Is this at all possible?

I'm trying to build the following structure on a page on my website:
The black border is the content container. The red border is the left content container and the gray area is the right content container with a gray background.
Now, I want the right content container to expand vertically dependent on the height of the left content container, so they will always have the same height.
How exactly do I go about this? Anyone know of a work-around to make the divs behave like a table would?
Thanks in advance!
All the best,
Bo

At the bottom of every project portal dashboard page for my TFS 2010 project portal () I get the message "" (see picture)
If I edit any of the dashboard pages (site actions of edit page) this message is still there, but not inside a web part which leads me to belive this is not a web part that is showing this message. But what is it? More to the point what do I need to do to fix it?
I presume I have some permissions or configuration issues, but currently both I and my companies internal support people are without a clue as to how we go about diagnosing never mind resolving this issue.
It should be pointed out that i/we are TFS 2010 newbies AND sharepoint 2007 newbies.
Any help would be much apreciated.

In a small WebView app I wrote, I am able to load YouTube and see the picture the represents a video clip, with the familiar right-pointing arrow that is supposed to start playing the video:
But... when I touch that arrow, nothing happens (the video is NOT played).
I did enable the plugins setting in WebView, but that didn't help:
```
mWebView.getSettings().setPluginsEnabled(true);
```
So, I searched for more clues about how to make Flash (YouTube) run embedded in my WebView and I found the following [hint](https://stackoverflow.com/questions/2943947/how-to-enable-flash-plugin-in-webview):
> I think you also need Flash to be
installed, like in Android 2.2 and
above.
I am OK with the requirement for Android 2.2 but what I don't understand is what "install Flash plugin" means: YouTube plays fine in Android's default browser (which is based on WebView AFAIK) and also in the YouTube app that's also installed in my device. Doesn't that mean that the Flash plugin is already installed?
If the answer is "no", what do I need to do to install it?

I am going over the Big-Oh notation, and I have a problem understanding the solution to this question:
```
Is 2n + 10 ≡ O(n)?
Can we find c and n0?
2n + 10 <= cn
(c-2)n >= 10
n >= 10/(c-2)
Pick c = 3 and n0 = 10
```
There is also a graph used in this example:
I am confused as to how c = 3 and how n0 = 10? Can somebody please enlighten me?

In internet explorer, when I have a field dynamically generated, everything moves down. However, the surrounding container stays the same height and everything just moves on past it.
Try clicking 'Add a Language' or 'Add a Skill' then scroll down to the bottom.
Any suggestions?
[](http://quspot.com/ie_test/)[http://quspot.com/ie_test/](http://quspot.com/ie_test/)
EDIT/
The syntax is
```
<div id="content">
<div class="wrapper"></div>
</div>
```
.wrapper is expanding just fine (I added a background color to make sure), the #content div is not though.

Hej All,
I upgraded my solutions of a project from vs2008 to vs2010.
But right now I have a weird problem. I reference a project in multiple solutions (3 solutions)
In 2 of those solutions the referencing goes wrong.
I am able to add the reference (project reference) but when I build I got the warning the referenced project x does not exists. And errors that I have to add an reference.
I already deleted and added the project again, same with the references but no result.
Does anybody have any idea?
Greetz,
Jonathan

I am building an IE Addon in C#. I uninstall my addon using Programs and Features. But it doesn't work out. The toolbar stays there on the browser. Tried Manage Addons from Tool Menu in IE. It displays Unavailable, but doesn't give an option to Remove or Uninstall it. I am unable to remove it fully. Also, when I rebuild my SetUp and reinstall it, it's not reflecting the changes as the old one is still there.
Even I deleted the Keys from the Registry.
Also there are other Addons which aren't built by me and still show the same behaviour.
Please see the Screenshot.
Please guide me to uninstall or say remove these.
Regards

I'm trying to make a tab thing out of buttons. So the selected button gets its' class changed so the bottom border is now WHITE.
The effect is to make it look like part of the connecting page.
HOWEVER, when I add margin-bottom:-2px; to the class - HOPING TO COVER THE PORTION OF MY DIV BORDER - it still shows the div border.
IF I make it -3px, then I get the WHITE background over the div... BUT now I have 1 pixel of left and right border sticking underneath the bottom... overflow:hidden doesnt work because it sets me back to the DIV border showing...
Anyone run into this problem before?
Thanks!
Todd
HERE IS THE -2px - Notice, BLUE BORDER STILL SHOWING:
AND here is what happens if give it -3px ... NOW blue side borders sticking through (ugh!)
HERE IS HTML:

When I first asked this question, I didn't fully understand what the problem was. Your best bet is to glance over the issue below and then read my answer.
---
I have a report with a matrix where the data looks like the following:
```
Name Id Activity 1 Activity 2 …Acitivity N
Smith 1 77 100 nn
Johnson 2 88 99 nn
```
and are in a group.
When the number of activities are greater than 11, I need the columns and to repeat when the report renders in a PDF.
---
Here is an example of report recently run:
> Page 1 (NOTE: red boxes indicate
personal data filtered out):
---
Page 2:
I've been fiddling with the properties and , but I have had no success.
How do I make this column repeat?

I'm setting up a mail merge file that reads from a CSV file. In the CSV file, there are ~20 Boolean fields that produce the body of the Word mail merge file. The problem is that if the first 19 fields are all `"N"`, then the Word mail merge file will have 19 blank spaces and then output the 20th field underneath all of them. Is there any way to suppress the output of these blank lines using the built-in mail merge rules?
---
Here's the header and a sample row of the CSV file:
```
"firstname","lastname","PRNT1040","LEGALGRD","ACADTRAN","STUD1040","VERWKSIN","VERWKSDP","UNEMPLOY","SSCARD","HSDPLOMA","DPBRTCFT","DEATHCRT","USCTZPRF","SLCTSERV","PROJINCM","YTDINCM","LAYOFFNT","MAJRCARS","W2FATHER","W2MOTHER","W2SPOUSE","W2STUDNT","2YRDEGRE","4YEARDEG","DPOVERRD"
"Joe","Smith","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","N","Y"
```
Here's a couple lines of the mail merge file that I'm trying (image linked because copying and pasting of mail merge does not show original document)
---
Does anyone know how to get around this? I tried placing the `SKIPIF` in front of the conditionals, but that doesn't work either.

Example: I have 20 persons as object, and every person knows 0-n others. The direction of the link matters! A person A might know B, but B might not know A. It's a directed graph.
So in the worst case everyone is connected with everyone else, everyone knows everyone else.
This is no real use case but I want to write a test for this to learn and play around. In a productive environment the number of objects would be limited to about 20, but the ways in which those objects are connected to eachother are unlimited.
This illustrates the problem in a simplified way:
 [thanks to source](http://labspace.open.ac.uk/course/view.php?id=5022)
Given a specific person as starting point, I want to walk through the whole graph and examine every possible path exactly once without getting stuck in an infinite loop.
Let's imagine person A knows B, who knows C, and who knows A. The output might be:
A knows B knows C knows A (ok but we don't want to end in an infinite loop so we stop here)
A knows C knows A
A knows T knows R knows V
This would be stupid and must be eliminated:
A knows B knows C knows A knows C knows A knows T knows R knows V ...
I do have a couple of crazy ideas how to tackle this problem. But...
Question) Must I do that with an Iterative deepening depth-first search (IDDFS)?
---
Jon was so kind to point out [DFS on Wikipedia](http://en.wikipedia.org/wiki/Depth-first_search)
I'm stuck with this part in the article:
> a depth-first search starting at A,
assuming that the left edges in the
shown graph are chosen before right
edges, and assuming the search
remembers previously-visited nodes and
will not repeat them (since this is a
small graph), will visit the nodes in
the following order: A, B, D, F, E, C,
G. The edges traversed in this search
form a Trémaux tree, a structure with
important applications in graph
theory.
specifically this note:
> "(since this is a small graph)"
OK so what if this is a huge graph?
|
Should I iterate over a directed graph using Iterative deepening depth-first search (IDDFS)?

Process Hacker has a process manager in C.
When you double-click in process manager on a process e.g. Explorer
You see a lot of info, including:
Topics related to the process. PDD, Cycles Delta Start, Address, priority.
Well I tried to do something similar in Delphi, but I get only the TID and priority ...
I can not put the info Start Address as follows: "msiltcfg.dll 0x258!" or can only return
00630EFA.

I am finally working on my [n-point Pade code](https://stackoverflow.com/questions/5294376/using-fold-to-calculate-the-result-of-linear-recurrence-relying-on-multiple-previ), again, and I am running across an error that was not occurring previously. The heart of the matter revolves around this code:
```
zi = {0.1, 0.2, 0.3}
ai = {0.904837, 1.05171, -0.499584}
Quiet[ RecurrenceTable[ {A[0] == 0, A[1] == ai[[1]],
A[n+1]==A[n] + (z - zi[[n]]) ai[[n+1]] A[n-1]},
A, {n, Length@ai -1 } ],
{Part::pspec}]
```
(The use of `Quiet` is necessary as `Part` complains about `zi[[n]]` and `ai[[n+1]]` when `n` is purely symbolic.) The code itself is part of a function that I want a symbolic result from, hence `z` is a `Symbol`. But, when I run the above code I get the error:
```
RecurrenceTable::nlnum1:
The function value {0.904837,0.904837+0. z} is not a list of numbers with
dimensions {2} when the arguments are {0,0.,0.904837}.
```
Note the term `{0.904837,0.904837+0. z}` where `0. z` is not reduced to zero. What do I need to do to force it to evaluate to zero, as it seems to be the source of the problem? Are there alternatives?
Additionally, as a general complaint about the help system for the Wolfram Research personnel who haunt stackoverflow: in v.7 `RecurrenceTable::nlnum1` is not searchable! Nor, does the `>>` link at the end of the error take you to the error definition, but takes you to the definition of `RecurrenceTable`, instead, where the common errors are not cross-referenced.
: After reviewing my code, the solution I came up with was to evaluate the `RecurrenceTable` completely symbolically, including the initial conditions. The working code is as follows:
```
Clear[NPointPade, NPointPadeFcn]
NPointPade[pts : {{_, _} ..}] := NPointPade @@ Transpose[pts]
NPointPade[zi_List, fi_List] /; Length[zi] == Length[fi] :=
Module[{ap, fcn, rec},
ap = {fi[[1]]};
fcn = Module[{gp = #, zp, res},
zp = zi[[-Length@gp ;;]];
res = (gp[[1]] - #)/((#2 - zp[[1]]) #) &[Rest@gp, Rest@zp];
AppendTo[ap, res[[1]]];
res
] &;
NestWhile[fcn, fi, (Length[#] > 1 &)];
(*
The recurrence relation is used twice, with different initial conditions, so
pre-evaluate it to pass along to NPointPadeFcn
*)
rec[aif_, zif_, a_, b_][z_] :=
Evaluate[RecurrenceTable[
{A[n + 1] == A[n] + (z - zif[n])*aif[n + 1]*A[n - 1],
A[0] == a, A[1] == b},
A, {n, {Length@ap - 1}}][[1]]];
NPointPadeFcn[{zi, ap, rec }]
]
NPointPadeFcn[{zi_List, ai_List, rec_}][z_] /; Length[zi] == Length[ai] :=
Module[{aif, zif},
zif[n_Integer] /; 1 <= n <= Length[zi] := zi[[n]];
aif[n_Integer] /; 1 <= n <= Length[zi] := ai[[n]];
rec[aif, zif, 0, ai[[1]]][z]/rec[aif, zif, 1, 1][z]
]
Format[NPointPadeFcn[x_List]] := NPointPadeFcn[Shallow[x, 1]];
```
Like the built-in interpolation functions, `NPointPade` does some pre-processing, and returns a function that can be evaluated, `NPointPadeFcn`. The pre-processing done by `NPointPade` generates the list of `ai`s from the `zi`s and the function values at those points, in addition to pre-evaluating the recurrence relations. When `NPointPadeFcn` is supplied with a `z` value, it evaluates two linear recurrence relations by supplying it with the appropriate values.
: for the curious, here's `NPointPade` in operation
In the first plot, it is difficult to tell the difference between the two functions, but the second plot shows the absolute (blue) and relative (red) errors. As written, it takes a very long time to create a Pade for 20 points, so I need to work on speeding it up. But, for now, it works.

I am looking to develop a webpage specifically for viewing on an iPhone/mobile browsers. The layout would be something like this:
I would like the two tabs at the top to be fixed, i.e. they would always appear at the top of the viewport/screen, and the content in each tab to scroll (the height of the content in each tab would exceed the remaining available height, and so I would want this to scroll).
Ideally there would also be a transition on switching tabs (perhaps a simple fade would work best with the graphics capability of the iPhone), though this is not essential.
I would be grateful for any advice in getting this set up,
Thanks,
Nick

For a school assignment me and a friend have been working on rendering a cube on a 2D surface(the screen) using a 2D-library(slick)
To do this we use the method described here [3D-projection - Wikipedia the free encyclopedia](http://en.wikipedia.org/wiki/Perspective_projection#Perspective_projection).
We use a 3x3 matrix to rotate the 3D-vectors which represents points on the cubes surface. Then We project the 3D vectors onto a plane(the screen) located on the positive X-axis using this method:
```
public Vector2D translate2D(Vector3D v){
Vector3D trans = translate(v);//Rotates the vector into position
float w = -trans.getX()/(700) + 1;
float x = (trans.getZ())/w;
float y = (trans.getY())/w;
return new Vector2D(x, y);
}
```
where translate() rotates the vector into the correct position and w adds some perspective to the cube.
I need to know which sides of the cube to render and which to not render(i e which are facing the viewer and which aren't). As long as you don't use perspective(w) this is easy. The cube always shows three sides to the user and to find these all you needed to do was:
1. Get the side's normal
2. Translate it using the rotational matrix
3. If the translated normals X-component was positive, then the side was facing the positive X-direction and therefore was to be visible to the viewer.
This because the screen is located directly on the positive X-axis.
Now, because of perspective, the viewer is facing 1-3 sides depending on the rotation of the cube. As mentioned I have access to each side's normal(unit vectors pointing straight away from each side) and the matrix which handles the rotation as well as the above method.
(edit) Thank you for your answer horatius83 but here's my problem: I dont know he surfaces normal since the side's normal is slightly distorted due to the added perspective.
Here are some images to describe my problem further
Without perspective(side's normal=surface normal):
With perspective showing 3 sides(side's normal!=surface normal):
With perspective showing 3 sides but should only be showing 1(side's normal!=surface normal)
(edit) the code determining whether the side should be rendered is very simple and not entirely correct since we're using the side's normal as if there was no perspective(as in image 1). If there is perspective this must be compensated for in some way. I just don't know how.
```
public boolean sideVisible(Vector3D normal){
if (translate(normal).getX()>0) {
return true;
}else{
return false;
}
}
```

This is my very first C program and I'm using this example libcurl code from their website:
```
#include <stdio.h>
#include <curl/curl.h>
int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://google.com/");
#ifdef SKIP_PEER_VERIFICATION
/*
* If you want to connect to a site who isn't using a certificate that is
* signed by one of the certs in the CA bundle you have, you can skip the
* verification of the server's certificate. This makes the connection
* A LOT LESS SECURE.
*
* If you have a CA cert for the server stored someplace else than in the
* default bundle, then the CURLOPT_CAPATH option might come handy for
* you.
*/
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
#endif
#ifdef SKIP_HOSTNAME_VERFICATION
/*
* If the site you're connecting to uses a different host name that what
* they have mentioned in their server certificate's commonName (or
* subjectAltName) fields, libcurl will refuse to connect. You can skip
* this check, but this will make the connection less secure.
*/
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);
#endif
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
return 0;
}
```
So in xcode I created a "group" called it curl and added all the files in the curl directory:
And now I'm getting these Build errors:
What am I doing wrong? Any advice would help, thanks!

As you can see, it's easy to create the design except the browse button of upload control. I created the rest. I've been searching about changing the place of Browse button but could not find anything useful.
So, how to do that? There was an idea like embedding an unvisible upload control over button but any other advice is golden, thanks.

Now what I am doing is having a text nav but then on hover still keeping the text but using an image as the background.
Because the text is varying sizes & the background image is one size it's becoming a problem because I only have 597px to work within for the nav area & I also want the same amount of spacing between each nav selection.
I want this for example..
But currently I am getting this:
The nav background image is 87px in width, so obviously it's wrapping because we don't have enough space. But we also end up with varying amounts of space between each nav item because each is set to 87px.
So I was wondering if there was any clean way to do what I want without using javascript & without the nav items jumping around when hovering over others?
I've tried putting differing widths on the different states but the nav just jumped around & looked terrible.
Any idea to do what I'm wanting?
If you would like to see my current HTML & CSS it's below:
HTML:
```
<div class="nav_wrapper">
<ul class="nav">
<li><a href="index.php">HOME</a></li>
<li><a href="about.php">ABOUT US</a></li>
<li><a href="services.php">SERVICES</a></li>

<li><a href="">BLOG</a></li>
<li><a href="free_quote.php">FREE QUOTE</a></li>
<li><a href="contact_us.php">CONTACT US</a></li>
</ul>
<!-- Nav Ends -->
<div class="contentClear"></div>
</div>
<!-- Nav Wrapper Ends -->
```
CSS:
```
#header .nav_wrapper {

}

I've just begun using breakpoints to debug a T-SQL stored procedure in Management Studio (SQL Server 2008). I notice that the breakpoints window has a condition column:
But I can't find any way to actually on a breakpoint, not via the Debug menu, not via a context menu on the breakpoint or within the breakpoint window, etc.
Is there a way to use conditional breakpoints in SSMS, or does that column exist for some future version?
|
Can conditional breakpoints be set while debugging in SSMS?

I try to create a TableLayout with multi rows, and each row is having different columns
The following show list view. For each row of list view, it contains a table layout with only 1 row, 2 columns.
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">
<ImageView
android:id="@+id/color_label"
android:layout_width="12dip"
android:layout_height="fill_parent"
android:layout_marginRight="6dip"
android:background="#ffffff" />
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow>
<TextView
android:id="@+id/toptext"
android:gravity="left"
/>
<TextView
android:id="@+id/bottomtext"
android:gravity="right"
/>
</TableRow>
<View android:layout_height="2dip"
android:background="#FF909090" />
</TableLayout>
</LinearLayout>
```
Here is the outcome.
Later, I want to further improve the TableLayout. With its 1st row is having 2 columns. and its 2nd row is having 4 columns, with a vertical line separates 1,2 columns with 3,4 columns.
I use the following code.
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">
<ImageView
android:id="@+id/color_label"
android:layout_width="12dip"
android:layout_height="fill_parent"
android:layout_marginRight="6dip"
android:background="#ffffff" />
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow>
<TextView
android:id="@+id/toptext"
android:gravity="left"
/>
<TextView
android:id="@+id/bottomtext"
android:gravity="right"
/>
</TableRow>
<View android:layout_height="2dip"
android:background="#FF909090" />
<TableRow>
<TextView
android:id="@+id/col1"
android:gravity="left"
android:text="Column 1"
/>
<TextView
android:id="@+id/col2"
android:gravity="right"
android:text="Column 2"
/>
<TextView
android:id="@+id/col3"
android:gravity="left"
android:text="Column 3"
/>
<TextView
android:id="@+id/col4"
android:gravity="right"
android:text="Column 4"
/>
</TableRow>
<View android:layout_height="2dip"
android:background="#FF909090" />
</TableLayout>
</LinearLayout>
```
Here is the outcome.
However, the 2nd row of table layout is not something I want. What I wish to have is something like this.
How can I improve my XML to achieve the above effect?

I've got an annoying issue, if someone needs additional information please say, as I'm not sure what I should put up here to make the question clearer! In the first picture I have the current layout, I wanted to move the star ratings to below the pictures in the dashed div of the other users.
But when I do it , everything gets fugly, as you can see in the second picture. Does anyone know what I should be looking at to ensure the stars end up below the div with pictures of hte images. I've put my css at the bottom.
```
#gallery { margin-left:auto;
margin-right:auto; background:#EEE; float: left; border: width: 500px; solid 1px #BBBBBB ; border-style: dashed; } * html #gallery { height: 12em; } /* IE6 */
.gallery.custom-state-active { background: #eee; }
.gallery li { float: left; width: 96px; height:86px padding: 0.4em; margin: 0.4em 0.4em 0.4em 0.4em; text-align: center; }
.gallery li h5 { margin: 0 0 0.4em; cursor: move; }

On this OpenGL application that I'm developing on Windows 7 with Visual Studio, I tried to enable Anti-Aliasing on the NVIDIA Control Panel (only for the application .exe).
Enabling that causes a little bit of distortion in lines/quads drawn in orthographic projection.
Anti-aliasing is turned off on the left and turned on on the right:
How can this be fixed keeping anti-aliasing on?
In case it's relevant, here's how the orthographic projection is setup and how black border is drawn:
```
void drawHeadsUpDisplay(void) {
static int winWidth, winHeight;
winWidth = glutGet(GLUT_WINDOW_WIDTH);
winHeight = glutGet(GLUT_WINDOW_HEIGHT);
glPushAttrib(GL_ENABLE_BIT);
glDisable(GL_DEPTH_TEST);
glDisable(GL_LIGHTING);
glMatrixMode(GL_PROJECTION);
glPushMatrix();
glLoadIdentity();
gluOrtho2D(0.0f, winWidth, winHeight, 0.0f);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glBegin(GL_LINE_LOOP);
glColor3f(0.0f, 0.0f, 0.0f);
glVertex2f(winWidth - 41, 48);
glVertex2f(winWidth - 41, winHeight - 48);
glVertex2f(winWidth - 18, winHeight - 48);
glVertex2f(winWidth - 18, 48);
glEnd();
glMatrixMode(GL_PROJECTION);
glPopMatrix();
glMatrixMode(GL_MODELVIEW);
glPopAttrib();
}
```

As you can see in the picture above, a ClickOnce application is being run directly off of a webpage to be installed. Is there a way to mimic this ability? I plan on making my own installer but I want installing the software to be as easy and fast as possible (my software is aimed towards teens and older children). Does anybody have any ideas? I'm using vb.net so any .net examples are appreciated.
Thanks if you can! I don't, however, need people to tell me alternate methods than the one proposed. This is the way I'm doing it and how it needs to be :)
Basically, once you click on a link in a browser, a similar dialog will pop-up asking (instead of saying "Install // Don't Install") if you would like to run the program?

In Silverlight 4 (using Expression Blend 4), how can I alter the Font size of a `TextBox` within the style of the `Border` containing it? I'm converting the style from WPF to Silverlight (fun always). Here is what I have:
```
<Style x:Key="Title" TargetType="Border">
<Setter Property="TextBlock.VerticalAlignment" Value="Center"/>
<Setter Property="TextBlock.TextAlignment" Value="Center"/>
<Setter Property="TextBlock.FontSize" Value="48"/>
<Setter Property="TextBlock.Foreground" Value="{StaticResource TextForeground}"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="Background" Value="{StaticResource TitleBackground}"/>
<Setter Property="Padding" Value="25,0"/>
</Style>
```
It is not working. It gives me the following exception in the designer:
Ok, I know this is possible in WPF. Is it simply not possible in Silverlight (without taking on a whole theme construct as Xin suggests?)

Today I wrote a program for detecting circles using Hough Transform using OpenCV in C.
The program inputs 3 images, each image contains a fixed small circle and a big circle with variable position. The program then recognizes both the circles and marks the centres of both the circles. Now what I want to do is that in the output image the (x,y) coordinates of the centre of the bigger circle should be displayed with respect to the centre of the fixed smaller circle . Here's the code for 'circle.cpp'
```
#include <cv.h>
#include <highgui.h>
#include <math.h>
int main(int argc, char** argv)
{
IplImage* img;
int n=3;
char input[21],output[21];
for(int l=1;l<=n;l++)
{
sprintf(input,"Frame%d.jpg",l); // Inputs Images
if( (img=cvLoadImage(input))!= 0)
{
IplImage* gray = cvCreateImage( cvGetSize(img), IPL_DEPTH_8U, 1 );
IplImage* canny=cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,1);
IplImage* rgbcanny=cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
CvMemStorage* storage = cvCreateMemStorage(0);
cvCvtColor( img, gray, CV_BGR2GRAY );
cvSmooth( gray, gray, CV_GAUSSIAN, 9, 9 ); // smooth it, otherwise a lot of false circles may be detected
cvCanny(gray,canny,50,100,3);
CvSeq* circles = cvHoughCircles( canny, storage, CV_HOUGH_GRADIENT, 2, gray->height/4, 200, 100 );
int i;
cvCvtColor(canny,rgbcanny,CV_GRAY2BGR);
for( i = 0; i < circles->total; i++ )
{
float* p = (float*)cvGetSeqElem( circles, i );
cvCircle( rgbcanny, cvPoint(cvRound(p[0]),cvRound(p[1])), 3, CV_RGB(0,255,0), -1, 8, 0 );
cvCircle( rgbcanny, cvPoint(cvRound(p[0]),cvRound(p[1])), cvRound(p[2]), CV_RGB(255,0,0), 3, 8, 0 );
}
cvNamedWindow( "circles", 1 );
cvShowImage( "circles", rgbcanny );
//Displays Output images
sprintf(output,"circle%d.jpg",l);
cvSaveImage(output,rgbcanny);
cvWaitKey(0);
}
}
return 0;
}
```
And here are the input and output images:
  
  
Please suggest what changes should I make in the code to display the desired (x,y)coordinates. Thanx a lot :)

Am not even sure if this can be done but...
Ive added a feed from my forums to wordpress it works great but I need it to auto add the url of the image in a custom field from the images in the post (feed) first image would be fine as its only ahve a slider
Is there any way to do this?
Ok I think I did not explain this very well so made a few screen shots
This is my slider at the minute with my
This is an imported post one other feed I was using
On this image you can see the custom field (which I have to fill in after every import)
Adding the image url into the custom field
and finaly a view of the slider working
This is what am trying to do (auto) so my feed from my booru / forums / 2 other of my sites and (2 other peoples) sites make my home page on a new site
Hope this explain it alot more

I would like to draw a popup in X11. Something like the slider that appears in KDE and GNOME when you press volume or brightness control buttons. This is what it looks like in GNOME: 
What library should I use to create such popups (unlike normal windows they should be without borders, etc. and possibly with some transparency)? Would be nice if there were bindings for Python.

Main purpose of application I'm working on in WPF is to allow editing and consequently printing of songs lyrics with guitar chords over it.
You have probably seen chords even if you don't play any instrument. To give you an idea it looks like this:
```
E E6
I know I stand in line until you
E E6 F#m B F#m B
think you have the time to spend an evening with me
```
But instead of this ugly mono-spaced font I want to have `Times New Roman` font with kerning for both lyrics and chords (chords in bold font). And I want user to be able to edit this.
This does not appear to be supported scenario for `RichTextBox`. These are some of the problems that I don't know how to solve:
- `TextPointer`
.
```
E E6
I know !!!SOME TEXT REPLACED HERE!!! in line until you
```
-
.
```
E E6
think you have the time to spend an
F#m B F#m B
evening with me
```
-
.
```
F#m E6
...you have the ti me to spend...
```
- `Ta VA``A``V``A``<TextBlock FontFamily="Times New Roman" FontSize="60">Ta VA</TextBlock>``<TextBlock FontFamily="Times New Roman" FontSize="60"><Span>Ta V<Floater />A</Span></TextBlock>`
Any ideas on how to get `RichTextBox` to do this ? Or is there better way to do it in WPF? Will I sub-classing `Inline` or `Run` help? Any ideas, hacks, `TextPointer` magic, code or links to related topics are welcome.
---
## Edit:
I'm exploring 2 major directions to solve this problem but both lead to another problems so I ask new question:
1. Trying to turn RichTextBox into chords editor - Have a look at How can I create subclass of class Inline?.
2. Build new editor from separate components like Panels TextBoxes etc. as suggested in H.B. answer. This would need a lot of coding and also led to following (unsolved) problems: Components will change their Width/Height according to they layout position (white space removal at line beginning etc.) Kerning will have to be inserted manually at components boundaries. How to make RichTextBox look like TextBlock? (not elegant hack/workaround is known)
---
## Edit#2
[Markus Hütter's high quality answer](https://stackoverflow.com/questions/5796457/create-guitar-chords-editor-in-wpf-from-richtextbox/5845927#5845927) has shown me that a lot more can be done with `RichTextBox` then I expected when I was trying to tweak it for my needs myself. I've had time to explore the answer in details only now. Markus might be `RichTextBox` magician I need to help me with this but there are some unsolved problems with his solution as well:
1. This application will be all about "beautifully" printed lyrics. The main goal is that the text looks perfect from the typographic point of view. When chords are too near to each other or even overlapping Markus suggests that I iteratively add addition spaces before its position until their distance is sufficient. There is actually requirement that the user can set minimum distance between 2 chords. That minimum distance should be honored and not exceeded until necessary. Spaces are not granular enough - once I add last space needed I'll probably make the gap wider then necessary - that will make the document look 'bad' I don't think it could be accepted. I'd need to insert space of custom width.
2. There could be lines with no chords (only text) or even lines with no text (only chords). When LineHeight is set to 25 or other fixed value for whole document it will cause lines with no chords to have "empty lines" above them. When there are only chords and no text there will be no space for them.
There are other minor problems but I either think I can solve them or I consider them not important. Anyway I think Markus's answer is really valuable - not only for showing me possible way to go but also as a demonstration of general pattern of using `RichTextBox` with adorner.

I have been working on a project where I need to load a ssrs site within an iframe. The iframe is acutally using the telerik spitter panels but the DOM refers to it as an iframe when rendered. The issue I am coming into is when referencing the SSRS site it loads wihtin the iframe but the view tiled multiple times over. In reading I have seen mention that the SSRS site also uses iframes which causes an issue when loaded into another iframe. Does anyone know of a solution for this type of scenario or can you point me in the right direction of where to look? In essence I have to wrap an asp.net wrapper around the SSRS site as it is a part of a larger site and users need to be able to navigate to this section of the site using the main navigation. I need to avoid pop-up windows or redirects as the user needs to get the expereince that they are in the same site even though I am loading ssrs from another server. Attached is a screen shot of what the tiling looks like. The site is small so I am not using masterpages it is loaded directly within an asp.net document.
Any tips or suggestions are always appreciated. Thank you

I am getting a memory leak on the following code line:
The code-line:
```
NSArray *fetchedObjects = [qContext executeFetchRequest:fetchRequest error:&error];
```
I have been trying to read-up on this and have tried to find the cause of this for quite some time, without success.
Could someone give me a hint where to look? ...and do i understand the "100%" correctly that it indicate that this code line is 100% causing the leak?
Some more code:
```
//=========PREPARE CORE DATA DB===========//
if (managedObjectContext == nil) { managedObjectContext = [(FamQuiz_R0_1AppDelegate *)
[[UIApplication sharedApplication] delegate] managedObjectContext]; }
// Define qContext
NSManagedObjectContext *qContext = [self managedObjectContext];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription
entityForName:@"questions" inManagedObjectContext:qContext];
[fetchRequest setEntity:entity];
NSArray *fetchedObjects = [qContext executeFetchRequest:fetchRequest error:&error];
for (NSManagedObject *info in fetchedObjects) {
if ([[info valueForKey:@"qDiff"] intValue] == 1) {
[allEasyArrayQ addObject:[info valueForKey:@"idQ"]];
} else if ([[info valueForKey:@"qDiff"] intValue] == 2) {
[allMediumArrayQ addObject:[info valueForKey:@"idQ"]];
} else if ([[info valueForKey:@"qDiff"] intValue] == 3) {
[allHardArrayQ addObject:[info valueForKey:@"idQ"]];
}
}

I was wondering if there was an easy way to add parameters to a service connection? Essentially I want to do something as simple as passing a integer through a service connection where all available methods have the ability to access this parameter.
Here's a diagram of the design:
Essentially application servers will get an id that can be passed when communicating with a WCF services for many reasons. Is there an easy way to integrate this functionality into a wcf service to be used by methods at runtime?
The functionality I'm looking for is something like:
Service1Client myService = new Service1Client();
myService.customValue = 1234;
That will be passed globally to all methods within that service.

I have view table that looks like this:
And I started to create a view to summarize by status for each currency:
```
WITH C AS (SELECT * FROM CampaignsPublisherReportSummary)
SELECT
'Total' T,
SUM(CASE WHEN PayCurrency='USD' THEN Total END) USD,
SUM(CASE WHEN PayCurrency='EUR' THEN Total END) EUR,
SUM(CASE WHEN PayCurrency='GBP' THEN Total END) GBP,
SUM(CASE WHEN PayCurrency='AUD' THEN Total END) AUD
FROM C
UNION
SELECT
'ToBePaid' T,
SUM(CASE WHEN PayCurrency='USD' THEN ToBePaid END) USD,
SUM(CASE WHEN PayCurrency='EUR' THEN ToBePaid END) EUR,
SUM(CASE WHEN PayCurrency='GBP' THEN ToBePaid END) GBP,
SUM(CASE WHEN PayCurrency='AUD' THEN ToBePaid END) AUD
FROM C
GO
```
I could finish and get what I want by copy/pasting again for each of the other status (Unverified, Verified, ...etc) but the programmer in me wants to have some kind of function that takes the the status name and runs a templatized version of the query...
QUESTION: Can I do this? Or is there another better way to break the information down that I'm missing?
UPDATE: My goal is to have something like this:
```
SELECT * FROM #mytempfunc('Total')
UNION SELECT * FROM #mytempfunc('ToBePaid')
UNION ...
```

I'm building a little sticky notes app for fun, and sometimes this happens:
(It's because the first word is wider than the width of the note.)
Is there a way to check whether the scrollbar is present with Javascript? If I can do that, I can resize the note until it contains the text without the scrollbar.

Every few weeks I check my application for memory leaks using instruments ( awesome tool, really ). As you can see in the screenshots there are a few memory leaks in it. I used to ignore these as I never really knew why they were there and they didn't seem to increase anyways.
They are created on launch and well.. thats all I know about them.
Anyone any ideas on how I can figure out what library or part of my code is causing these leaks?
-- thanks

Good day,
I have been given an assignment that gets data off a CSV file. The CSV file contains the following entries:
LName,FName,Dept,Grade,Gross Pay, Tax Paid, Net Pay.
I am able to retrieve the data and display it in the console window which is shown in my code below. However, I need help with displaying the results according to dept and getting the total net pay in each dept. There are three depts M, R, And S.
```

I'm having a problem with lighting when dealing with really small particles. I'm doing particle-based fluid simulation and am right now rendering the fluid as really tiny polygonized spheres (by really tiny I'm saying about 0.03 units radius for the spheres). The lighting in my scene isn't lighting them how I want and I can't get it to look right. I'm looking for something similar to the soft lighting on the particles in this image...
However my particles look like this...
See how my particles have bright white sections whereas the green particles are just lit up softly and don't have large white hotspots. I know the reason is either the settings for my light or simply the fact that the particles are so small that the light takes up a larger space (is that possible??). My settings for lighting are as follows...
```
GLfloat mat_ambient[] = {0.5, 0.5, 0.5, 1.0};
GLfloat mat_specular[] = {1.0, 1.0, 1.0, 1.0};
GLfloat mat_shininess[] = {10.0};
GLfloat light_position[] = {0.0, 0.1, p_z, 1.0};
GLfloat model_ambient[] = {0.5, 0.5, 0.5, 1.0};
glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient);
glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);
glLightfv(GL_LIGHT0, GL_POSITION, light_position);
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, model_ambient);
glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);
glEnable(GL_DEPTH_TEST);
glShadeModel(GL_SMOOTH);
glColorMaterial(GL_FRONT_AND_BACK,GL_AMBIENT_AND_DIFFUSE);
glEnable(GL_COLOR_MATERIAL);
```

## Question:
The generated XML file from an .XSD template produces the output pasted below. Since `category`'s keys are `image`, my standard way of parsing the `image` items wont work on `category`. I would like to place the `category name="Category #"` into an array, How can I make an array from the category fields.
## What I need:
What I want is an array of dictionaries. Each position contains a dictionary representing one category, and each dictionary contains images for that category.
> `Array: @"Category 1",@"Category 2",@"Category 3";``For each Array, a Dictionary with: <image>``</image>`

}
});

contentPane.add(label);
JLabel label_1 = new JLabel("New label");
label_1.setIcon(new ImageIcon("C:\\Users\\achermen\\Desktop\\down.png"));
label_1.setBounds(447, 159, 46, 48);

label_4.setBounds(447, 112, 46, 48);

}
}
```
This is the code to draw a line
```
public void paint(Graphics graphics)
{
graphics.drawLine(10, 20, 300, 310);
}
```
So how to use this lines ....
Thanks in advance.
Best regards,
Ali

I'm creating a simple game and come up with this problem while designing AI for my game:
Given a set of N points inside a rectangle in the Cartesian coordinate, i need to find the widest straight path through this rectangle. The path must be empty (i.e not containing any point).
I wonder if are there any efficient algorithm to solve this problem? Can you suggest any keyword/ paper/ anything related to this problem?
EDIT: The rectangle is always defined by 4 points in its corner. I added an image for illustration. the path in the above pictures are the determined by two red lines

I am writing my little Android app. I pop up a dialog control which is a nice, non-fullscreen, rounded-corners dialog by setting `android:theme="@android:style/Theme.Dialog"` on the activity in my manifest. That all works just as I expected. However it is just a drab, grey-titled dialog as in this screenshot:
I've noticed however that a LOT of applications, when they pop up dialogs have a nice, blue-themed title as in this screen shot.
I would assume this theme is some common theme, as it shows up in a LOT of different apps. I would assume it is something built in to the OS. (My phone is a Captivate with the official Froyo release). Of course it COULD be something that every developer simply re-coded on their own, but I doubt that.
Assuming that this is a common theme, how do I utilize it in my app? What changes do I need to make to my activity to have it use that theme?
Thanks in advance!

I am running Emacs 23.3 on Windows XP. When Emacs is started, the mode line will assume one of these two appearances at random. Needless to say, I prefer the first one. How do I figure out what is going on and how do I make the first one stick?
The images don't show it, but the first one has a GUI type appearance. If I hover over the various bits of text with a mouse, e.g. then the text turns into a button with shadows etc.
The black mode line appears to be a text mode widget. The only thing that the mouse will change on it is the highlighting.
PS: Thanks JSON!

I've got a SQL query which is trying to find all the Neighbourhoods in some Counties.
When I use SQL Sentry Plan Explorer to visualize the query (IMO, a bit better than the tools provided with MS SSMS) it highlights a really slow performing part :-
Full Plan
Zoomed in ....
Details
SQL script:
```
-- Update which Neighbourhoods are in these Counties.
INSERT INTO @NeighbourhoodCounties (NeighbourhoodId, CountyId)
SELECT SubQuery.NeighbourhoodId, SubQuery.CountyId
FROM (
SELECT e.LocationId AS NeighbourhoodId, b.LocationId AS CountyId,
c.OriginalBoundary.STArea() AS CountyArea,
c.OriginalBoundary.STIntersection(d.OriginalBoundary).STArea() AS IntersectionArea
FROM @CountyIds a
INNER JOIN [dbo].[Counties] b ON a.Id = b.LocationId
INNER JOIN [dbo].[GeographyBoundaries] c ON b.LocationId = c.LocationId
INNER JOIN [dbo].[GeographyBoundaries] d ON c.OriginalBoundary.STIntersects(d.OriginalBoundary) = 1
INNER JOIN [dbo].[Neighbourhoods] e ON d.LocationId = e.LocationId
) SubQuery
WHERE (SubQuery.IntersectionArea / SubQuery.CountyArea) * 100 > 5 -- a Neighbourhood has to be 5% or more to be considered 'Inside'
```
Can anyone help interpret this query? What do all these numbers mean? How can I use these numbers to help diagnose and improve my query?

Hey guys, this is driving me absolutely crazy! Been searching for hours and can't seem to figure out a solution. Any ideas how to do something like this:
Notice how there are two buttons inside of the tableviewcell, asnd notice how the grouped tableview has a background.
Any ideas?
Thank you!

I have got four tabs. I was able to change the tab icon color from default blue to red (or probably any color) and it works perfectly fine. The problem is it works only for three tabbaritems and last one is default blue. Below is the code. I'm coding this in `rootviewcontrollerAppDelegate.m` You could try this by pasting the below code in your appdelegate. Could you guys help me out I'd be so greatful!

I'm trying to allow users that have connected their Facebook accounts to my rails app to find their Facebook friends that have already registered in the app, preferably in an index like format (similar to Formspring's display).
Currently I'm using Devise, OAuth+Fbook Javascript SDK, and Koala. I have the Facebook UID of each user that connects their Facebook saved in the db, but I don't know how to filter through the results of the Facebook API call @friends = @graph.get_connections("me", "friends") in order to display the users that have matching UID's to the API call data.
Any thoughts? There's probably an even better way, so lemme know if any additional info is needed. Thanks very much for your help!
EDIT (screenshot of index action in users controller)
Note in @oauth, app id and app secret are cropped out in the example image

routine.routineExercises = exercises;

I'm working with jQuery Mobile and one of my pages is giving me problems.
I have a `<p>` embedded in a list like so:
```
<div data-role="page">
<div data-role="header">
<h1>Page 1</h1>
</div>
<div data-role="content">
<ul data-role="listview">
<li data-role="list-divider">
List Heading
</li>
<li>
<p>A very long paragraph that <b>should</b> be wrapped when it exceeds the length of the visible line.</p>
</li>
</ul>
</div>
</div>
```
No matter what I do, the page looks something like this:
The `<p>` is getting clipped. I tried wrapping it in a `<div>`, but it remains the same. Since the `<p>` is pulled from an external source, I would prefer solutions that don't modify the `<p>` or the contents of it.
|
How to keep this <p> from getting clipped when it exceeds the width of the page?

It's incredible that such sample code doesn't even work.
I have put this inside grid but I can't see any line (code taken from MSDN in fact):
```
<Canvas Height="103" HorizontalAlignment="Left" Margin="30,166,0,0" Name="canvas1" VerticalAlignment="Top" Width="180">
<Line
X1="0" Y1="10"
X2="5" Y2="10"
Stroke="Black"
StrokeThickness="4" />
</Canvas>
```
This is incredible that such simple thing like that would be so buggy so did I miss something see picture below ? (Everything else in silverlight works fine for me):
Update: the bug is confirmed. This is quite incredible that MS hasn't fixed this !

We have been working on a Google Maps API v3 based app for the past few weeks when we noticed that the click event on one type of marker had stopped working. We had changed the size and upped the number of these markers, assumed our code was bad but a revert didn't fix the issue.
Our code was fairly simple. After creating a marker (called obj in this example) we would do the following:
```
google.maps.event.addListener(obj, 'click',
function(coords){ localClick(coords, id); });
```
`localClick` is one of our functions, `alert('click!');` also yielded nothing.
After a few days of scratching our heads, we noticed something odd: some of the markers working. Then we noticed a horizontal line of almost invisible markers that were clickable but in the wrong place:
This happens on all browsers on OSX (we didn't try on Windows or Linux).
One solution was to specify the version of the API you are using to v3.2. This isn't ideal as we'd like to stay up to date. And it was working on the latest edition (v3.4) until recently.
Call in the Google maps API like this and it's not working:
```
$.getScript("https://maps-api-ssl.google.com/maps/api/js?
sensor=false&callback=mapLoaded");
```
Like this and everything's great:
```
$.getScript("https://maps-api-ssl.google.com/maps/api/js?
sensor=false&v=3.2&callback=mapLoaded");
```
We're puzzled.
Unfortunately we cannot post the code or a working demo (I know this reduces the response rate, client requirements).

I need to create a graph as shown in the image below. I have the values for the upper limit, lower limit and the average for each question. Can anyone suggest a plugin in Ruby on Rails to create such a graph shown in the image?
Edit:
I am finding it difficult to find something which does clear the area from the X-axis(Question axis) to the lower limit. Can anyone help me with this?

The output looks like this
Questions:
1. How do I set a initial or default value?
2. How do I remove the bullet points
3. How do I get rid of the text 'This field is required.'
I had a good look at the documentation on djangoprojects but there doesn't seem to be anything on it unless I missed something?

I have a class defined as:
```
public class Student
{
public string Id { get; set; }
public IDictionary<string, string> Attributes { get; set; }
}
```
based on the discussion I found here : [http://groups.google.com/group/ravendb/browse_thread/thread/88ea52620021ed6c?pli=1](http://groups.google.com/group/ravendb/browse_thread/thread/88ea52620021ed6c?pli=1)
I can store an instance quite easily as :
```
//creation
using (var session = store.OpenSession())
{
//now the student:
var student = new Student();
student.Attributes = new Dictionary<string, string>();
student.Attributes["NIC"] = "studentsNICnumberGoesHere";
session.Store(student);
session.SaveChanges();
}
```
However when I query it as below:
```
//Testing query on attribute
using (var session = store.OpenSession())
{
var result = from student in session.Query<Student>()
where
student.Attributes["NIC"] == "studentsNICnumberGoesHere"
select student;
var test = result.ToList();
}
```
I get the error "'System.Linq.Expressions.InstanceMethodCallExpressionN' to type 'System.Linq.Expressions.MemberExpression'." as shown:

i am still very new to objective c and in fact this is my first attempt to build an app so please bear with me...
I am trying to add an UITable beside core-plot graph, i have taken CPTestApp example and stated to work off that, i was able to get the graph part working ok but i am having trouble with UITable. Below is the screenshot of how it look at the moment.UITable is upside down and the text is all mirrored..
below is rotation part, can someone point me with an example for UITable rotation together with graph...UITable is populated with an array of values and that is working ok too..
i probably need some guidance to figure out the correct way to add UItable to the coreplothosting view layer
Thanks
```
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
if (UIInterfaceOrientationIsLandscape(fromInterfaceOrientation))
{
// Move the plots into place for portrait
scatterPlotView.frame = CGRectMake(20.0f, 55.0f, 728.0f, 556.0f);
tblSimpleTable.frame = CGRectMake(20.0f, 644.0f, 728.0f, 340.0f);
[tblSimpleTable reloadData];
}
else
{
// Move the plots into place for landscape
scatterPlotView.frame = CGRectMake(20.0f, 55.0f, 858.0f, 677.0f);
tblSimpleTable.frame = CGRectMake(878.0f, 51.0f, 220.0f, 677.0f);

imagine this situation:
# SetUp
in the default MVC3 project, create a new complex type in the `AccountModels.cs`
```
public class GlobalAccount
{
public GlobalAccount()
{
this.LogOn = new LogOnModel();
this.Register = new RegisterModel();
}
public LogOnModel LogOn { get; set; }
public RegisterModel Register { get; set; }
}
```
In the `RegisterModel` change the `UserName` to:
```
[Required]
[Remote("UserNameExists", "Validation", "", ErrorMessage = "Username is already taken.")]
[RegularExpression(@"(\S)+", ErrorMessage = "White space is not allowed.")]
[Display(Name = "Username (spaces will be stripped, must be at least 6 characters long)")]
public string UserName { get; set; }
```
The `UserNameExists` method in a `Validation` controller is as follow:
```
public class ValidationController : Controller
{
public JsonResult UserNameExists(string UserName)
{
string user = null;
if (!String.IsNullOrWhiteSpace(UserName) && UserName.Length >= 6)
user = UserName == "abcdef" ? "ok" : null;
return user == null ?
Json(true, JsonRequestBehavior.AllowGet) :
Json(string.Format("{0} is not available.", UserName), JsonRequestBehavior.AllowGet);
}
}
```
Now in the Register View, use the `GlobalAccount` Model instead of the `RegisterModel`
the username input box will be like:
```
@model Your.NameSpace.Models.GlobalAccount
```
and
```
<div class="field fade-label">
@Html.LabelFor(model => model.Register.UserName, new { @class = "text" })
@Html.TextBoxFor(model => model.Register.UserName, new { spellcheck = "false", size = "30" })
</div>
```
this will result in something like this, in the HTML
```
<div class="field fade-label">
<label class="text" for="Register_UserName"><span>Username (spaces will be stripped, must be at least 6 characters long)</span></label>
<input data-val="true" data-val-regex="White space is not allowed." data-val-regex-pattern="(\S)+" data-val-remote="Username is already taken." data-val-remote-additionalfields="*.UserName" data-val-remote-url="/beta/Validation/UserNameExists" data-val-required="The Username (spaces will be stripped, must be at least 6 characters long) field is required." id="Register_UserName" name="Register.UserName" size="30" spellcheck="false" type="text" value="">
</div>
```
# Debug
If you use FireBug to check what's going on ... the is sending the attribute instead of the attribute to the Validation method (the `UserNameExists` one) as:
`Register.UserName` instead of `Register_UserName`
So I can't fetch this value ... :(
Is this really a bug or is something that someone already found and I couldn't get from Googling it?
Here is a simple image of the actual problem:

Till now I have got it so far
but as you can see leg is protruding out of the wall, i want to know how to chip off that extra paint.
I guess it can be done with `clip()` function but I'm not sure how to use it.
Here is what i want

//save the current state with fillcolor
ctx.save();
//draw 2's base rectangle
ctx.fillRect(20,200,120,35);
//bring origin to 2's base
ctx.translate(20,200);
//rotate the canvas 35 deg anti-clockwise
ctx.rotate(acDegToRad(35));
//draw 2's slant rectangle

When I try to deploy my MVC3 application on IIS7, on every URL I am getting an Http 500 - Internal Server Error.
The site runs fine in development in Visual Studio.
And I can request simple html pages, or aspx pages, and they return fine.
I've tested if asp.net works by adding an aspx page that returns inline <%= DateTime.Now.ToShortDateString() %>, which also works fine.
So I think the problem is situated with MVC itself or the Routing.
MVC3 is installed on the server, but I also tried bin deploying by setting all MVC related references to `copy local = true`.
Any ideas ?
Edit:
I enabled failed request tracing, which results in no error logs.
Customerrors are off & Server errors are detailed :
```
<httpErrors errorMode="Detailed" />
<asp scriptErrorSentToBrowser="true"/>
<customErrors mode="Off"/>
```
The only thing I am getting is a 500 - Internal Server Error header with a blank page.
I checked the event log for the webserver, nothing to find.
After some restarts I'm getting a somewhat more detailed error :

<!-- Child Control -->
<GW1:OrgChart ID="OrgChart1" runat="server" />

In OOP languages I might write a database wrapper which encapsulates database connection, manages schema and provides few core operations, such as `exec`, `query`, `prepare_and_execute`. I might even have a separate database helper class which would handle the database schema, leaving the database abstraction only to handle connections. This would then be used by model wrappers/factories which use the database abstraction class to create instances of model classes. Something along the line like this UML diagram:
What would be the preferred way to design such a system in idiomatic haskell?

Noticed a small sorting problem in a DataGrid we are using.
When a DataGrid column header is clicked, the default alternating ascending/descending sorting takes place. Fine. But when all of the row items in a column are the same, and the column header is clicked, some sorting still takes place, but only for the first click, and this not occur on subsequent clicks.

Flex DataGrid sorting problem - sorts even when no sort necessary

I am having a kinda strange problem.
Here is the situation. I have a `ListView`, with a custom defined `GroupStyle` to make data appear in `Expander`s, in which there is a `WrapPanel` containing `StackPanels` (which contain one ToggleButton + one custom control)
The custom control in the `StackPanel` is not visible by default, and becomes visible when the `ToggleButton` is checked.
However, when I check a `ToggleButton`, the custom control appears, and all the other control situated on the same line will move to a vertical center.
Ideally, I'd like these other members to stay on top. I've tried to set `VerticalAlignment="Top"` everywhere I could, it doesn't change anyway.
Imaged problem:
The initial state of an expander:
Once the `ToggleButton` is clicked, here is what happens:
As you can see, the button "Test Analysis" is moved to stay at the center. I want it to stay in the same place than the original.
Moreover, I've defined all of these styles in separate `DataTemplate`s objects.
Here is some light code (I just removed what's useless for the problem here, won't make you read tons of XAML code :) ):
The expander's content property:
```
<Expander.Content>
<WrapPanel Background="White" VerticalAlignment="Top">
<ItemsPresenter VerticalAlignment="Top"/>
</WrapPanel>
</Expander.Content>
```
The list's `ItemsPanel` :
```
<ItemsPanelTemplate >
<WrapPanel
Width="{Binding (FrameworkElement.ActualWidth),
RelativeSource={RelativeSource
AncestorType=Expander}}"
ItemWidth="{Binding (ListView.View).ItemWidth,
RelativeSource={RelativeSource AncestorType=ListView}}"
ItemHeight="{Binding (ListView.View).ItemHeight,
RelativeSource={RelativeSource AncestorType=ListView}}" />
</ItemsPanelTemplate>
```
The list's `ItemsTemplate` :
```
<StackPanel Orientation="Vertical" Height="Auto" Width="Auto" VerticalAlignment="Top" >
<ToggleButton BorderBrush="{x:Null}" Background="{x:Null}" IsChecked="{Binding Value.IsToLaunch, Mode=TwoWay}"
Command="{Binding DataContext.UpdateGroupCheckingsCommand,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type UserControl}}}">
<Grid Background="Transparent">
<!-- Blah blah blah about the ToggleButton's content -->
</Grid>
</ToggleButton>
<my:UcReleaseChooser>
<!-- Blah blah blah about being visible if ToggleButton is Checked -->
</my:UcReleaseChooser>
</StackPanel>
```

Is there a feature in HTML that the label has a specific width and when it needs to render over its given width, it should clip and show `...`. And in the tooltip, the full actual name is shown.
Something like this:

I need to produce a table similar to:
What we see is the left column containing the data point headers, and each column after contains the actual data.
I'd like to treat each column (other than the first one) as an optional column. The user can add or remove the columns based on funds they select. If they've selected only 1 fund, only the first 2 columns are visible, the rest of the spaces are blank. Each subsequent fund selection adds a new column to the table, up to a max of 5.
I'm wondering what is the best way to implement this? I'm thinking each column is an independent table of a fixed width that I can add to a container which can align them side by side. Will I have difficulty getting the 6 tables to line up side by side?
Is there a better way for me to achieve this result?

As a small project to get myself used to some more iPhone elements I've decided to create a sample in call screen, modeling it on the native iPhone call screen (IOS 4)
However I'm struggling to make out what elements the native in call screen uses to make up the view that is displayed.
I was wondering if someone with more experience on iPhone could help me out by explaining what the various elements are?
Is the bottom part a UIActionSheet that is slightly transparent and with a UIBUtton placed over it? Or is it a slightly transparent imageview with the button over-layed?
Similarly at the top, it looks like its an imageiew with the name or number of the callee/caller and the call duration underneath, would I be correct in thinking that?
The part I'm really interested in is the bit where the icons are held in some sort of dialog in the centre of the screen that is animated to swing around to a keypad when it is selected, is this some sort of iPhone control that I can use or customise?
I've tried two things to try to achieve this so far:
1) I've created a view within a view and I am trying to flip this however I can only seem to get the main view to flip properly and not the view inside it which is the one I want and it doesn't seem to be a good approach.
2) I've tried to look at using the Utility application approach to it but again this seems to be for flipping the full screen and not just a section within a screen (view)
Has anybody got any pointers on what to try next? Or if one of the above methods is the ideal way to do it and should be investigated further?

I have a set of tables which are connected through foreign keys , and almost all of them have the primary keys as auto increment identifier of sql server. The figure is given below .
Now when I am adding a row in storyboard table I need to know the auto generated storyboard Id on inserting the row so that using that I can insert the slides associated with it into slide table.
For this should I query the database for the Id created or is there any other way to use this ? Please tell me how to do this in sql server 2008
I am using asp dot net web service to interact with sql server.

Yesterday I was having fully compiled ASP.NET MVC 3.0 project. Today when i opened my project again it is wont compiled because of T4MVC, I was very surprised.
I readd the T4MVC template thorough NuGet again, but it is didn't help. Then i removed all related T4 VS 2010 extensions: T4 Editor, T4Utilites, and Visual T4, opened project again but it is didn't help, than i rebooted and installed T4 extensions again but it is didn't help either. Than i created new clean ASP.NET MVC 3.0 project and add T4MVC to this, and I've got the same errors (see peintscreen).
If i remove T4MVC.tt from solution than I can compile the project, but when i am put it back, I am getting errors again.

I think that the problem with Visual Studio, and now I have a very bad idea - try to reinstall Visual Studio, but may be some one may suggest something better?
p.s 1
Also I didn't install anything related to Visual Studio this days, may be only a couple of small Upstates through windows update, but they wasn't related to visual studio.
Also i have MVC 3.0 Updates tools' installed, but before today everything was working well.
It is looking very strange, i can generate *.cs files successfully using this template, there is no errors i am getting during this process, but visual studio blaming T4MVC.tt fore some reason.
p.s 2
Actually also NuGet package where updated. May be it is the case? mmm... But after removing NuGet all the same :(

I am using the GWT Activities and Places framework to structure my application and it is turning out nicely. One thing that annoys me though is that the `ActivityMapper` implementation is (1) receiving all the views in the application (2) contains a giant if/else block for instantiating activities based on the received place. It will only get worse as the number of views increases.
I am already using [Gin](http://code.google.com/p/google-gin) but I don't see how I can use it here.
How can I reduce or eliminate the boilerplate from my `ActivityMapper`?

I have an image such as this:
I want to have it so I can use these images for different buttons and other parts without having to split the image myself. I've seen lots of games and programs do this without needing to split it. How would I do this? I'm using VB.net so any .net examples are appreciated!
You can see an example here:
This image is used as a minimap in a game I play, the different pieces are cut at runtime.

I've a UINavigationController and in the picture you can see a UIViewController added to it.
Now, I would like to customize the top bar of the UINavigationController with the content of the current visible UIViewController. More in particular, I would like:
1. add the title
2. customize "back" button text
Should I use self.navigationController method from the current UINavigationController ? If so, what are the next steps ?
Thanks

I'm working on an .obj file loader for OpenGL using Objective-C.
I'm trying to get objects to load and render them with shading. I'm not using any textures, materials, etc. to modify the model besides a single light source. When I render any model, the shading is not distributed properly (as seen in the pictures below). I believe this has something to do with the normals, but I'm not sure.
These are my results:
And this is the type of effect I'm trying to achieve:
I thought the problem was that the normals I parsed from the file were incorrect, but after calculating them myself and getting the same results, I found that this wasn't true. I also thought not having `GL_SMOOTH` enabled was the issue, but I was wrong there too.
So I have no idea what I'm doing wrong here, so sorry if the question seems vague. If any more info is needed, I'll add it.
Update:
Link to larger picture of broken monkey head: [http://oi52.tinypic.com/2re5y69.jpg](http://oi52.tinypic.com/2re5y69.jpg)
Update 2: If there's is a mistake in the process of me calculating normals, this is what I'm doing:
- - -
:
```
static inline void normalizeVector(Vector3f *vector) {
GLfloat vecMag = VectorMagnitude(*vector);
if (vecMag == 0.0) {
vector->x /= 1.0;
vector->y /= 0.0;
vector->z /= 0.0;
}
vector->x /= vecMag;
vector->y /= vecMag;
vector->z /= vecMag;
}
```
Update 3: Here's the code I'm using to create the normals:
```
- (void)calculateNormals {
for (int i = 0; i < numOfIndices; i += 3) {
Triangle triangle;
triangle.v1.x = modelData.vertices[modelData.indices[i]*3];
triangle.v1.y = modelData.vertices[modelData.indices[i]*3+1];
triangle.v1.z = modelData.vertices[modelData.indices[i]*3+2];
triangle.v2.x = modelData.vertices[modelData.indices[i+1]*3];
triangle.v2.y = modelData.vertices[modelData.indices[i+1]*3+1];
triangle.v2.z = modelData.vertices[modelData.indices[i+1]*3+2];
triangle.v3.x = modelData.vertices[modelData.indices[i+2]*3];
triangle.v3.y = modelData.vertices[modelData.indices[i+2]*3+1];
triangle.v3.z = modelData.vertices[modelData.indices[i+2]*3+2];
Vector3f normals = calculateNormal(triangle);
normalizeVector(&normals);
modelData.normals[modelData.surfaceNormals[i]*3] = normals.x;
modelData.normals[modelData.surfaceNormals[i]*3+1] = normals.y;
modelData.normals[modelData.surfaceNormals[i]*3+2] = normals.z;
modelData.normals[modelData.surfaceNormals[i+1]*3] = normals.x;
modelData.normals[modelData.surfaceNormals[i+1]*3+1] = normals.y;
modelData.normals[modelData.surfaceNormals[i+1]*3+2] = normals.z;
modelData.normals[modelData.surfaceNormals[i+2]*3] = normals.x;
modelData.normals[modelData.surfaceNormals[i+2]*3+1] = normals.y;
modelData.normals[modelData.surfaceNormals[i+2]*3+2] = normals.z;
}
```
Update 4: Looking further into this, it seems like the .obj file's normals are surface normals, while I need the vertex normals. (Maybe)
If the vertex normals are what I need, if anybody can explain the theory behind calculating them, that'd be great. I tried looking it up but I only found examples, not a theory. (e.g. "get the cross product of each face and normalize it"). If I know what I have to do, I can look it up an individual process if I get stuck and won't have to keep updating this.
Update 5: I re-wrote my whole loader, and got it to work, somehow. Although it shades properly, I still have those grid-like lines that you can see on my original results.
