4,214,304 | 1 | 4,214,475 | null | 5 | 5,398 | When the user focuses on a certain element, I display a save button. On `focusout`, I remove the save button.
The user can submit the input by either hitting return or click save. When they click the save button, the input loses focus and the save button is removed, thus not registering the click. Can I tell in the `focusout`, if the save button has been clicked?
Within my focus function I do something like this:
```
$('#save_button').click(function(){
saveEditingField(this); //save input
$('#save_button').die("click");
});
$('.editing').focusout( function(e) {
$('#isediting').attr('value','false');
$('#edit_controls').remove()
});
```
I've tried adding a delay to the `remove()`, but when tabbing between inputs it shows multiple save buttons (while the others are being removed).

In the next step, I am having a detailView which displays some properties of the selected file such as fileName, fileSize, filePath, fileType. Everything works perfect.
But actually my plan is to include a additional option in the detailView.
That is,
1. If the selected file in the tableView is a image file, it should open a imageView in the detailView to display that image.
2. If the selected file is a mp3, it should open a player to play the song in the detailView.
3. If the selected file is a video or mp4 file, it should open a player to play that video in detailView.
4. If the selected item is a folder, it should again open a tableView which dispalys the contents of the folder.
5. For other files, it should push a alertView regarding that it is a unknown file.
Hope my concept was narrated well. I got the methods for playing the .mp3 and .mp4 files. Now I am stuck in pushing the imageView and in case of a folder. I have no ideas to proceed both the methods.
This is my tableView
This is my detailView for video file
This is my detailView for a .mp3 file
This is the detailView left empty for my imageView.

4,215,608 | 1 | 4,215,640 | null | 3 | 1,020 | I'm having a little problem using Navigation properties and inheritance on ADO.NET.
This is my Data Model:
First, some vocabulary:
> Categoria = Category
Formulario = Form
Campo = Field
Imagem = Image
Paragrafo = Paragraph
Escolha = Choice
Texto = Text
Resposta = Answer
So, I'm trying to create a custom property on a Form returning it's answers count.
The normal approach (i think) would be:
```
public partial class Formulario
{
public int Respostas
{
get
{
List<Item> itens = this.Itens.ToList();
IEnumerable<Campo> campos = from m in itens where m as Campo != null select (Campo)m;
int soma = campos.Sum(m => m.Respostas.Count);
return soma;
}
}
}
```
But it doesn't work. The `itens` list returns 0 elements. But when I do as below, it return the 4 items it should:
```
public partial class Formulario
{
public int Respostas
{
get
{
FormulariosDB db = new FormulariosDB();
List<Item> itens = db.Items.Where(m => m.Formulario.Id == this.Id).ToList();
IEnumerable<Campo> campos = from m in itens where m as Campo != null select (Campo)m;
int soma = campos.Sum(m => m.Respostas.Count);
return soma;
}
}
}
```

It has got two span-elements inside. One with `float:left;` the other with `float:right;`.
The style is a normal button-style.
When clicking that button on the iPhone or hover it in a Browser the style gets lost.
This is because I changed the background-color.
Is there a way to change the background-color without losing the whole button-style?
EDIT:
Here are the two images: The first button is a normal button-element. The second button is a button where I changed the background-color ... this is what it looks like when I'm hovering over a button.

But when he prints it the part of the graph disappears in a pretty strange way. Here's a screenshot from printed PDF (same thing happens with actual printer)

```
PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{
dialog.PrintVisual(chart, "Chart");
}

If number of data points is relatively small everything prints out as expected.
Any ideas?

the issue i am having is that when my android application launces and tries to load the login page for facebook, that very same login page is blank and it only displays the the facebook logo as the title of the screen.
No login fields or buttons are visible leaving me nowhere to login and authenticate a user.
i have tried two API's one is facebook connect api for android [http://code.google.com/p/fbconnect-android/](http://code.google.com/p/fbconnect-android/) and the other one is the official android facebook sdk that is recommended to be used instead of the previous one i have just mentioned [https://github.com/facebook/facebook-android-sdk/](https://github.com/facebook/facebook-android-sdk/) .
please see the image below of how it looks like on my app.
Here is code that uses the latest android sdk facebook:
```
/**
* Authenticate facebook network
*/
private void authenticateFacebook() {
// TODO: move this away from this activty class into some kind of
// helper/wrapper class
Log.d(TAG, "Clicked on the facebook");
Facebook facebook = new Facebook(OAUTH_KEY_FACEBOOK_API);
facebook.authorize(this, new AuthorizeListener());
}
class AuthorizeListener implements DialogListener{

public void onComplete(Bundle values) {
// TODO Auto-generated method stub
Log.d(TAG, "finished authorizing facebook user");
}

}
@Override
public void onError(DialogError e) {
// TODO Auto-generated method stub
}

// TODO Auto-generated method stub
}
}
```
And a simple example of how to use it: [http://developers.facebook.com/docs/guides/mobile/](http://developers.facebook.com/docs/guides/mobile/)
My code is more or less identical to the above example.
edit: i did not catch what logcat was inputing in my first attempted at my code above but their was no exceptions or warnings thrown at the time. just a blank page.
i then tried it again and diddnt touch my code and what happens now is that a loading dialogue view pops up and stays their for a few minutes until the facebook windows disapears and the logcat outputs the error below:

from [worldmapper.org](http://www.worldmapper.org/). In this example, countries are scaled according to their population, resulting in near-constant population density.

I’d like to be able to do a projection of the dot in image 1 onto the space in image 2.
Note also for the image 1 I do not have a defined window or eye position. I just know that the red square from image 1 is a transform of the red square form image 2 and that the image 2 is in 2D space.

I want to display a table in data grid. The first column should be name of the table field, second column should be the value of the column.
now if the first column cell data type is var char , then second column cell should display text box.
if the first column cell data type is int, then second column cell should display combo box.

4,218,992 | 1 | 4,219,707 | null | 0 | 1,592 | I am working on a bilingual site in the latest version of Drupal 6. I installed the Internationalization module and the Views translation module, among many others.
The problem: On /admin/build/translate/search, some elements (e.g. the view title) appear in the text group "Views" and Drupal assumes they are in German, requiring an English translation.
Other elements (e.g. exposed filter labels) appear in the text group "Built-in Interface" and Drupal assumes they are in English, requiring a German translation. But in fact all the strings are in German:
To be clear, I am not seeing an issue with the language selection or the display of the view. The issue is when the page is first parsed by the language system and any translatable strings are inserted into the translation table. Drupal assignes different source languages for elements on the same page. The result is a mix of languages, once these strings are translated.
I thought that maybe it is the language preference of the user who hits the page first that interferes with this, but once I started changing it, I ran into [this issue](http://drupal.org/node/204946) (reading the thread was eye-opening - it should be mandatory reading for anyone considering Drupal for enterprise-class solutions). Ok, now I have the URL prefix in the mix, which means that when a user changes the language preference, the site language does not change until they manually change the URL.
Once I managed to get the page rendered in English, it turned out that Drupal does not pick up the translation strings when the display language equals the source language. So no luck there.
I am ready to code my view in 2 languages, depending on what Drupal thinks the source language is for the various elements, but even that won't work. Has anybody else experienced this?

4,219,125 | 1 | 4,219,542 | null | 0 | 654 | I have an UIViewController subclass and an IBOutlet named map to an MKMapView instance.
So far, so great, but sometimes the app crashes without a reason when the view controller triggers the `viewDidLoad` method. This is absolutely randomly, but only happens when I created around three instances and then create a new one and push it into a navigation controller (however, I have only one of these view controllers at the same time in the navigation controller stack!).
Here is the code of the `viewDidLoad` method:
```
- (void)viewDidLoad
{
[super viewDidLoad];
[map setDelegate:self];
[map setMapType:MKMapTypeStandard];
[map setShowsUserLocation:YES];
if(area)
self.area = area;

(Sorry for the picture, but I was too lazy to type it all).

4,220,228 | 1 | 4,220,290 | null | 0 | 385 | I have a form that appears as shown in the attached image. I have two parts of the form that concern this question: the TabControl, and the Panel, as shown in the image. It should be noted that the panel is NOT within the TabControl.
My situation is that I have a thread that executes continuously when the button, displayed in melt-your-eyes green in the Panel, is clicked. The thread polls the device which I'm interfacing with and updates the controls in the "Status" GroupBox at the bottom of the TabControl. When the user clicks on a control in the TabControl (`tabControl_Enter` event), I trigger a ManualResetEvent which lets the thread finish its iteration so that I can perform the IO required by the clicked control. The code to to suspend the thread is as follows:
```
private void StopSynchThread()
{
synchWaitHandle.Reset();
//various UI changes
}
private void updateSynchStat()
{
while (true)
{
synchWaitHandle.WaitOne();
try
{
updateSynch();
}
}
```
What I would like to do is then restart the thread automatically, instead of by button press, as is currently done. What I'm trying to do is avoid having to restart the thread by conditionally calling `StartSynchThread()` within each of the "bazillion" UI event handlers. `StartSynchThread()` is defined as:
```
private void StartSynchThread()
{
synchWaitHandle.Set();
}
```
Is there a precedent or decent paradigm for handling this? Without any concept of how to do so, I was thinking that I could alter my function that performs the IO with the device to generate an event after it gets a response from the device, but that seems inelegant.
Any ideas? I appreciate your insights. Thanks.

4,224,449 | 1 | null | null | 1 | 1,107 | There is a need for selecting specified number of points on the image (actually on the part of that image). Darker parts of the image are more important.
The easiest way of doing this is by selecting them randomly. But even dropping used points usually finished with some points being located too close to others especially when respecting weights.
Maybe after selecting the point the weight should be decreased dynamically? Haven't tried.
I've noticed that original image has too many different colors so I wanted to smooth it to cut off similar colors. However converting to grayscale was not enough.
I used [Emgu CV](http://www.emgu.com/) (OpenCV wrapper) functions to binarize image. Than I tried to calculate watershed but calculated areas are not so easy to separate. Generally watershed is pretty 'non-intuitive' approach to detect darker places.
Simply: I would like to mark points on the image starting from darker parts - that parts should be marked more frequently than lighter. Points should be scattered over group of colors that are similar to avoid being piled-up in nearby places.
The algorithm doesn't have to be accurate. It can give different results in next iterations. Number of points would not be very big from 10 to 150-200.
How to calculate specified number of points scattered on the image starting from the darker regions?
To visualize what I mean see the picture below. It contains selected points (qty. ~20). Mostly darker parts are selected. The points don't have to appear on the same locations after next iteration. But what I want is to select points on lighter regions when number of them would be higher.
Of course for different images the numbers of points needed to jump out of darkness would differ.

I had a django project which was running the application [django-brookie](https://github.com/bread-and-pepper/django-brookie).

I have since added [django-grappelli](http://code.google.com/p/django-grappelli/) to my project and everything works except for one small thing.
If you create a new invoice or quote it should total up the amount in your currency automatically. This is not working anymore and I really can't figure out why. Perhaps something with brookie's javascript clashing with grappelli's javascript?
Any suggestions welcome and if you need more info just ask.
Here is a screenshot of the items. When I place time in minutes it totals up without grappelli:

The strategy I used was simple: I created multiple carousels and hide them. Only the selected carousel will appear.
It works fine except for one thing: In Firefox (and now in IE8) I am forced to change to another tab of the browser and then get back or change the window size if I want to to see it the it should.
Of course, this is not the kind of thing that a user guesses or even tolerates.

Here's what I am trying to achieve:
Here's what is wrong:
When I change tabs in the browser or change the size of the window, it starts working correctly.
I believe that if I call and an handler for an event (like resize window, tabchanged or something like that). What do you think?

c.body.on('click', function() {
alert('ok');
});

```
[Ed: The Panel is never being rendered -- add renderTo config. Next, you'll hit a null error telling you that `c` is not a valid variable. Do you mean `menuItem1` instead?]

title: 'Start',
html: 'This is the start page.',
cls:'menuItem'
});
Ext.getCmp('panelStart').on('click', function() {
alert('ok');
});
```
[Ed: `click` is not a Panel event. Also, the Panel is not yet rendered, so if you switched the callback to be on the element rather than the Component you'd get a null error.]
gets error: Ext.get('panelStart') is null:
```
var menuItem1 = new Ext.Panel({
id: 'panelStart',
title: 'Start',
html: 'This is the start page.',
cls:'menuItem'
});
Ext.get('panelStart').on('click', function() {
alert('ok');
});
```
[Ed: It's not rendered, see above. Switching from `getCmp` to `get` means you are switching from referencing the `Component` (which does exist, but does not have a `click` event) to referencing the `Element` (which does have a `click` event, but is not yet rendered/valid).]
makes the panel disappear:
```
var menuItem1 = new Ext.Panel({
id: 'panelStart',
title: 'Start',
html: 'This is the start page.',
cls:'menuItem',
listeners: {
'render': {
fn: function() {
this.body.on('click', this.handleClick, this);
},
scope: content,
single: true
}
},
handleClick: function(e, t){
alert('ok');
}
});
```
[Ed: The scope being passed into the callback (`content`) is not a valid ref in this code (this was copy-pasted incorrectly from another sample). Since the Panel var is created as `menuItem1` and the callback is intended to run in the panel's scope, scope var should be `menuItem1`. Also, this Panel is never rendered, see prev comments.]
gives the error "Ext.fly(menuItem1.id) is null":
```
var menuItem1 = new Ext.Panel({
id: 'panelStart',
title: 'Start',
html: 'This is the start page.',
cls:'menuItem'
});
Ext.fly(menuItem1.id).addListener('click', Ext.getCmp(menuItem1.id) , this);
```
[Ed: Panel is not rendered, see above]
...put outside Ext.onReady()...
gets error: Ext.getCmp('panelStart') is null
```
Ext.getCmp('panelStart').on('click', function() {
alert('okoutside');
});
```
[Ed: Panel is likely not rendered at the time this code is run. Also, `click` is not a Panel event.]
...put outside Ext.onReady()...
gets error: Ext.get('panelStart') is null
```
Ext.get('panelStart').on('click', function() {
alert('okoutside');
});
```
[Ed: See above]
...put outside Ext.onReady()...
gets error: Ext.fly('panelStart') is null
```
Ext.fly('panelStart').on('click', function() {
alert('okoutside');
});
```
[Ed: See above]
For the last three, I checked in Firebug and `<div id="startPanel">` exists:
# It works with JQuery:
So with JQuery I simply have to do this and it works:
```
$('body').delegate(('#panelStart'), 'click', function(){
alert('ok with jquery');
});
```
[Ed: This is not a good approach. It's simply delaying attaching of the handler until later, when the element actually shows up in the DOM (which could also be done via Ext btw, but would still not be the proper approach). I spelled out the correct approach, as linked in my answer below. The OP's attempts are all very close, but each is missing one or two key pieces.]

4,225,764 | 1 | 4,511,028 | null | 2 | 846 | I'm attempting to create a grid of availability from a number of tables to present information as follows:
```
------------------------------------------------------
venue | 22/11 | 23/11 | 24/11 | 25/11 | 26/11 |
------------------------------------------------------
Some venue | £24 | £25 | £32 | N/A | £65 |
------------------------------------------------------
Some venue | £20 | N/A | £22 | £34 | £43 |
-------------------------------------------------------
```
For each venue I can create a recordset for the selected date period using a query such as:
```
SELECT temp_date.queryDate, availability.venueId
FROM temp_date
LEFT JOIN availability
ON temp_date.queryDate = availability.date
AND availability.venueId = 7
GROUP BY temp_date.queryDate
ORDER BY temp_date.queryDate;
```
The key here being that I can return a null value for any dates that are unavailable whilst keeping my recordset to the correct number of days (ie. 5 entries for a working week).
To add each of the other venues to this list I was considering simply using a UNION query to combine the datasets into one like so:
```
(SELECT temp_date.queryDate, availability.venueId
FROM temp_date
LEFT JOIN availability
ON temp_date.queryDate = availability.date
AND availability.venueId = 7
GROUP BY temp_date.queryDate
ORDER BY temp_date.queryDate)
UNION
(SELECT temp_date.queryDate, availability.venueId
FROM temp_date
LEFT JOIN availability
ON temp_date.queryDate = availability.date
AND availability.venueId = 8
GROUP BY temp_date.queryDate
ORDER BY temp_date.queryDate);
```
My concern with this is with say 10 different venues that could be queried then the query could take quite a long time to run through.
So my question is as follows: Is a UNION query my only option here or is there some alternative JOIN I can use to ensure that I get a full weeks results for all the venues being queried.
Hopefully this is clear :-S

In case of a table with 50,000 rows the query with the constant runs for 10 milliseconds and the one with the parameter runs for 30 seconds (3,000 times slower).
It is not an option to move the last `WHERE` clause to the anchor definition of the recursion, as I would like to use the query to create a view (without the last `WHERE`). The select from the view would have the `WHERE` clause (`WHERE Id = @Id`) - I need this because of Entity Framework, but that is another story.
Can anybody suggest a way to force query #2 (with the parameter) to use the same query plan as query #1 (with the constant)?
I already tried playing with indexes but that did not help.
If somebody would like I can post the table definition and some sample data as well.
I am using SQL 2008 R2.
Thank you for your help in advance!

4,226,276 | 1 | 4,226,332 | null | 1 | 5,411 | I am working through a facebook-sdk example and trying to utilize the collection of classes as provided as a .JAR. I am relatively new to java and eclipse so I expect I am making some obvious blunder.
The issue is that everything seems to compile fine, but when I run the project (using the android emulator) dalvik vm is unable to find the first class I reference from this facebook sdk. ( com/facebook/android/Facebook.class )
As an aside, if I copy the source directly into my project as an additional package everything works fine.
Step 1: I exported the com_facebook_android project as a .JAR file. ( right click project, export, java / jar file ) I choose c:\data\jag\jar as my location to save facebooksdk.jar.
Step 2: I hit properties on the project HelloGoogleMaps, Selected Java Build Path, Libraries, Add External JARS... I the directly selected the c:\data\jag\jar\facebooksdk.jar file.
At this point my project seems to be building just fine ( no errors ).
Step 3: Debug the project and receive the error:

4,226,356 | 1 | 4,226,473 | null | 9 | 3,316 | I'm struggling to find a rock solid solution to detecting collisions between a circle and a circle segment. Imagine a Field of View cone for a game enemy, with the circles representing objects of interest.
The diagram at the bottom is something I drew to try and work out some possible cases, but i'm sure there are more.
I understand how to quickly exlude extreme cases, I discard any targets that don't collide with the entire circle, and any cases where the center of the main circle is within the target circle are automatically true (E in the diagram).
I'm struggling to find a good way to check the rest of the cases. I've tried comparing distances between circle centers and the end points of the segments outer lines, and i've tried working out the angle of the center of the target circle from the center of the main circle and determining whether that is within the segment, but neither way seems to catch all cases.
Specifically it seems to go funky if the target circle is close to the center but not touching it (somewhere between E and B below), or if the segment is narrower than the target circle (so that the center is within the segment but both edges are outside it).
Is there a reliable method for doing this?
The segment is described by position P, orientation O (whose magnitude is the circle radius), and a view size, S.
My most successful attempt to date involved determining the angles of the vectors ca1 and ca2, and checking if either of them lies between the angles of vectors a1 and a2. This works for some cases as explained above, but not situations where the target circle is larger than the segment.
After implementing the best suggestion from below, there is still a false positive which I am unsure how best to eliminate. See the pink diagram below. The circle in the lower right is reporting as colliding with the segment because it's bounds overlap both half spaces and the main circle.
---
## Final Edit
After discovering another edge case (4th image), i've settled on an approach which combines the two top answers from below and seems to cover all bases. I'll describe it here for the sake of those who follow.
First exclude anything that fails a quick circle-to-circle test.
Then test for collision between the circle and the two outer lines of the segment. If it touches either, return true.
Finally, do a couple of point-to-halfspace tests using the center of the circle and the two outer lines (as described by Gareth below). If it passes both of those it's in, otherwise return false.

Here is a brief description of the application:
- The purpose of the Application is to allow the User to create "Events" that are going to be stored locally on the Device and sent over the network.- The User can interact with the application through 2 Activities: A "NewEventActivity" that allows him to create the new Events and a "LogbookActivity" that allows him to browse previously created Events.- The local storage should be handled by a SQLite Database- The Event should be sent in a specific Binary format.- Other applications should be able to Use the Sending component to Format and send other type of messages in the same format.
This drawing represents how I was thinking of organizing the components. Boxes represent components, and arrows represent interactions without those components.

4,226,852 | 1 | 4,230,118 | null | 0 | 5,001 | The question says it all:
My canvas application has been configured to enable the OAuth 2.0 for Canvas (beta) among other things.
This means I am getting the `signed_request` parameter on my iframe which I am successfully reading.
From the [oficial documentation on canvas authentication](http://developers.facebook.com/docs/authentication/canvas)
> The signed_request parameter is the concatenation of a HMAC SHA-256 signature string, a period (.), and a base64url encoded JSON object.
There is a php code in the documentation which decodes the `signed_request` but I haven't been able to implement it propertly in C# partly beacuse to be honest I prefer not to reinvet the wheel but to use someone else code that has been already tested.
This is where my quest for a good C# Facebook SDK started again (since facebook changes everything every few months librarys get usually obsolete).
I have used the codeplex's [Facebook Developer Toolkit](http://facebooktoolkit.codeplex.com/) in the past but it seems to be getting outdated ans the lastest stable release is very old (in facebook API time)
Some months ago used the [Oficial Facebook C# SDK](http://github.com/facebook/csharp-sdk) from GitHub but it lacks completly the authentication support.
Now I have found on Nuget and really liked the Facebook C# SDK from [Nathan Totten](https://stackoverflow.com/users/75505/nathan-totten) who is one of the [top Facebook Experts](https://stackoverflow.com/tags/facebook/topusers) here in StackOverflow.
If you Nathan read this (or anyone that also uses this sdk), how can I use this SDK to get an access token to use in my canvas app.
Anyway if there is a better way to get a token, maybe with the Javascript library please let me ( and the people who wonder the same as me ) know.

4,227,064 | 1 | 4,227,355 | null | 0 | 253 | On one page on my site, I have a table in the right column that is too wide and rather than showing scrollbars, IE is wrapping it below the content in the left column. I can't find a fix for this because I don't know how to describe what's happening.
Here's the code I'm using to demonstrate the problem:
```
<style>
#col1 { float: left; width:189px; font-size:8pt;}
#col3 { width: auto; margin: 0 0 0 191px; }
</style>
<body>
<div id="col1">
<div style="padding-top:30em;border:1px solid red">really tall</div>
</div>
<div id="col3">
<h1>title</h1>
<table border="1">
<tr>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>

<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
<td>aaaaaaaaaa</td><td>aaaaaaaaaa</td>
</tr>
</table>
</div>
</body>
```
And here's how it renders in IE:
In all other browsers, the table of a's shows just under "title" and I get a horizontal scrollbar. This is what I'd expect, but for some reason, IE wants to clear the content in col1. I've tried applying widths, floats, etc, but I can't get IE to put the table under the title without clearing the col1 content.
I assume there's some IE hack for this, but what is it?

Here is how it looks at runtime (title and then the child control is a GridView):

}
public override void RenderEndTag(HtmlTextWriter writer)
{
//base.RenderEndTag(writer);
writer.Write("</div></div>");
}
#endregion
}
}
```
As you see the code above, it is currently based off of the Panel control. However, I have also tried just using WebControl as the base class and then providing my own designer as follows:
```
namespace Shoe.Controls
{
public class ApplicationWindowDesigner : ContainerControlDesigner
//public class ApplicationWindowDesigner : ControlDesigner
{
/*
public override void Initialize(IComponent component)
{
base.Initialize(component);
SetViewFlags(ViewFlags.DesignTimeHtmlRequiresLoadComplete, true);
}
public override string GetDesignTimeHtml()
{
//return base.GetDesignTimeHtml();
StringBuilder sb = new StringBuilder();
TextWriter s = new StringWriter(sb);
HtmlTextWriter h = new HtmlTextWriter(s);
ApplicationWindow app_wnd = (ApplicationWindow)this.Component;
app_wnd.RenderControl(h);
h.Dispose();
s.Dispose();
return sb.ToString();
}
*/
/*
public override string GetDesignTimeHtml(DesignerRegionCollection regions)
{
//return base.GetDesignTimeHtml(regions);
ApplicationWindow app_wnd = (ApplicationWindow)this.Component;
/
return GetDesignTimeHtml();
}
*/
}
}
```
As you can see, I've tried using ControlDesigner as the base class and ContainerControlDesigner as the base class. When I use the ControlDesigner I get the designer to properly render my title bar and divs; however it does not render the child controls (GridView). If I use ContainerControlDesigner it renders the child controls, but not the title bar and divs. I cannot figure out the magic combination that will give me a designer that renders my surrounding frame and the child controls.
Here is what it looks like in the designer when using the Panel as the base class for the control, no designer, and the Begin / End tag approach:
This is also what it looks like when I use WebControl as the base class for the control and use a designer based off of ContainerControlDesigner (child controld, but my title bar and divs are missing).
What am I missing? I've found several examples of ContainerControlDesigner but none of them really add anything to the surrounding control like I am.

I've got a listview which uses a custom adapter. A row looks like this
The list is filled by an array. Everything works great.
Now, I want the ImageView and the ToggleButton to react to clicks, so I implement the OnClickListener in my adapter, put the items position in each view's tag, and then I set their onclicklistener to this.
Works great, except now I can't use the onListItemClick for starting an activity for the item! OK, I say, I just make the relativelayout holding the text in the middle there use the same onclicklistener. Works great. Everything is clickable, and life is good.
EXCEPT! Now, when I scroll the list, I cannot "continue" the scroll by just flinging again. This causes the scrolling to stop, and I have to fling once more to get it going again. It seems the onclick-thingy causes the fling-motion to be interpreted as a tap or something (it does not trigger the logic within onClick).
I know that this is possible by just going to the phone list on my HTC Hero, which has exactly the kind of layout and behaviour I want from my app. This app even seems to have the onItemClickListener working.
So how can I make sure the list keeps scrolling, and still be able to click the togglebutton, listitem and the imageview? I've been stuck on this all day, and it's giving me a headache :(

I have a javascript running on `https://xyz.com` which has to retrieve information from an application `ABC` running on the user's local machine say port 8080.
My constraints are that I cannot modify the HTTP headers emanating form the `ABC` nor do I want the user to install another application which will be a conduit to route my requests through to `ABC`.
a) Ruled out since I cannot have script running on the local machine
b) Ruled out since I cannot modify the header
c) Again this will not work since I am unable to enclose the response within the function name
As a workaround, only meant for testing I've added the `http://xyz.com` to the trusted list and have enabled `Access Data Across Domains` for sites on this list. AFAIK, this option is only available on IE 5+ browsers. This workaround allows me to send and receive messages from `http://127.0.0.1:8080`
My question is two-fold
1) If I were to continue with the above approach when I go into production what are the security implications that I'm exposing the user to? Can I plug those holes?
2) Are there any other options that I can pursue to achieve my objective.
I would like to be as far away from ActiveX or Flash as possible, but in case that is the only workable alternative to my current approach then I'll have to toe the line

For example, consider the code below:
```
function testGradient():void {
var g:Graphics = container.graphics;
var width:Number = container.width;
var height:Number = container.height;
var y:Number = 0;
var x:Number = 0;
var ratios:Array = [255 * y / height, 255 * (y + height) / height];
g.beginGradientFill(GradientType.LINEAR, [0xFF, 0xFF], [0.6, 0],
ratios, null);
g.lineStyle(1, 0xFF0000);
g.drawRect(x, y, width, height);
g.endFill();
}
```
When the rectangle being drawn lies within the bounds of `container`, everything works:
However, if the rectangle lies outside of the bounds of the container, the gradient isn't drawn at all. For example, if the code is changed to:
```
...
var x:Number = 10;
var y:Number = 10;
...
```
Then the gradient disappears:
Short of doing the math required to draw the box inside the bounds of the parent (and fixing up the gradient so it looks correct), is there any way to deal with this?

I have an entity called Incident, as you can see on the picture, it holds a list with several bugs.
Then I have a datagrid that I connect a list with all my incident to:
```
List<ExtendedIncident> allIncidents;
myGrid.ItemsSource = allIncidents;
```
Now I bind some of the values from every incident, like this in the xaml code:
```
<sdk:DataGrid AutoGenerateColumns="False" Name="grid" SelectionMode="Single" SelectionChanged="grid_SelectionChanged">
<sdk:DataGrid.Columns>
<sdk:DataGridTemplateColumn Header="Incident">
<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<HyperlinkButton Content="{Binding CallId}" Click="HyperlinkButton_Click"></HyperlinkButton>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
<sdk:DataGridTextColumn Header="Beskrivnig" Binding="{Binding Description}"></sdk:DataGridTextColumn>
<sdk:DataGridTextColumn Header="Beskrivnig" Binding="{Binding Status}"></sdk:DataGridTextColumn>
</sdk:DataGrid.Columns>
```
My problem now is that I would like to add some columns that presents some data from the bugs, that are relevant (stored in the list for the incident) in the same row. How can I present data from the list of buggs from the incident?
Would be very thankful for any help

1 View has 1 ViewModel. Sometimes Multiple Views has 1 ViewModel (using a ).
If you regard my image you see 6 colored Views/UserControls.
The YELLOW,GREEN and ORANGE UserControls
are used multiple times in my application.
The pink,blue and red UserControls are used only once.
Questions:
Should I make them UserControls too? If yes, why if I do not reuse them.
Assume those are 6 UserControls, should they share the same ViewModel?
OR should each View have its own ViewModel?

Send pupil to BLUE
E.)... many more
Is that the way to go, firing around data with a Messenger class to keep the relations up to date?
There is a major flaw for me:
I create a PupilViewModel but I do not know in the NewPupilViewModel(PINK) wether a SchoolclassCodeViewModel exists in the YELLOW UserControl so I could add my new PupilViewModel to the BLUE UserControl.
SchoolclassCodeViewModel 1 : N PupilViewModel.

// Now re-insert it at the destination.
[things insertObject:thing atIndex:[toIndexPath row]];
// All of the objects are now in their correct order. Update each

### further info
I'm currently involved in a pretty good sized project, and it's public facing log-ins are completely OpenID driven (Using [DotNetOpenAuth](http://www.dotnetopenauth.net/)). If this is going to be too challenging for users (as per the comments made around Scott's original tweet), I'm going to need to know of some GOOD alternative solutions... if there even is one.
Any information would be appreciated.
### edit
To clarify and rephrase. I'm not trying to launch a debate on ""... I'm simply asking "What is there to take the place of OpenID, should it be ". I'm also NOT saying that I think OpenID dead, but merely asking the question based on a comment made by a well respected developer.
### addition
As @marc pointed out in a comment. There is a pretty good rant/blog post by Rob Conery titled [Open ID Is A Nightmare](http://blog.wekeroad.com/thoughts/open-id-is-a-party-that-happened) where the Rob makes some pretty compelling arguments as to why OpenID is not desirable. I have to agree that I don't want to be wasting a large amount of time recovering accounts for my users, my time is better spent in other places.
So back to the original question. What is there for alternatives? Is there a better "standard" out there that is "open" yet doesn't fall apart if a provider decides to change something? (changing API's or encryption logic for example)... but also one that can span across multiple providers and still recognize a single user?

4,231,161 | 1 | 4,236,219 | null | 1 | 1,362 | I am developing a Genetic Algorithm framework and initially decided on the following `IIndividual` definition:
```
public interface IIndividual : ICloneable
{
int NumberOfGenes { get; }
double Fitness { get; }
IGene GetGeneAt(int index);
void AddGene(IGene gene);
void SetGeneAt(int index, IGene gene);
void Mutate();
IIndividual CrossOverWith(IIndividual individual);
void CalculateFitness();
string ToString();
}
```
It looked alright, but as soon as I developed other classes that used `IIndividual`, I came to the conclusion that making Unit-Tests for those classes would be kind of painful. To understand why, I'll show you the dependency graph of `IIndividual`:
So, when using `IIndividual`, I end up to also having to create/manage instances of `IGene` and `IInterval`.
I can easily solve the issue, redefining my `IIndividual` interface to the following:
```
public interface IIndividual : ICloneable
{
int NumberOfGenes { get; }
void AddGene(double value, double minValue, double maxValue);
void SetGeneAt(int index, double value);
double GetGeneMinimumValue(int index);
double GetGeneMaximumValue(int index);
double Fitness { get; }
double GetGeneAt(int index);
void Mutate();
IIndividual CrossOverWith(IIndividual individual);
void CalculateFitness();
string ToString();
}
```
with the following dependency graph:
This will be pretty easy to test, at the expense of some performance degradation (I'm at this moment not that worried about that) and having `IIndividual` heavier (more methods). There is also a big problem for the clients of IIndividual, as if they want to add a Gene, they'll have to add all the little parameters of Gene "manually" in `AddGene(value, minimumValue, maximumValue)`, instead of `AddGene(gene)`!
## My question is:
What design do you prefer and why? Also, what is the criteria to know where to stop?
I could do just the same thing I did to `IIndividual` to `IGene`, so anyone that uses `IGene` doesn't have to know about `Interval`.
I have a class `Population` that will serve as a collection of `IIndividuals`. What stops me from doing the same I did to `IIndividual` to `Population`? There must be some kind of boundary, some kind of criteria to understand in which cases is best to just let it be (have some dependencies) and in which cases it is best to hide them (like in the second `IIndividual` implementation).
Also, when implementing a framework that's supposed to be used by other people, I feel like the second design is less pretty (and is maybe harder for others to understand).
Thanks!

I find that binding (`Window1.Options`) is being set (after stepping through code in debug mode), the markdown editor options (supposed to set Fonts, Colors etc) does not get set, or at least the UI does not update. I want to bug whats happening with in the `MarkdownEditor.xaml.cs` but thats another (referenced) project. How can I verify that the `MarkdownEditor.Options` is being set at least?
I have actually tested that the `MarkdownEditor` side is working by the below

<me:MarkdownEditor Options="{Binding Options, RelativeSource={RelativeSource AncestorType=Window}}" Grid.Row="1" />

So the difference is the latter is a `MarkdownEditor` just in a `Grid` in a `Window`. The one failing is a `MarkdownEditor` within a `TabControl` bound to a `ObservableCollection<TabViewModel>`
I am not really good at explaining things, so a simple project I made up minus all the unnecessary noise uploaded to [media fire](http://www.mediafire.com/?d88dsine5vug5gz) so you can take a look at whats wrong
The video showing the problem on [Screenr](http://screenr.com/hQc)
With just a simple usage, editor in a window/grid.
the binding works ok
Then when used in conjunction with `TabControl` bound to `ObservableCollection<EditorTabViewModel>`, the binding works as shown in the 2 `TextBox`es updating its values. but the editor does not update

This worked before I started passing the session as an instance variable, instead of keeping track of specific string, driver, car and track objects. Since [[self session] driver], would return nil when a new session object is passed, a dictionary object cannot be used. This is how I do it now...
```
//these come in handy, they're the object names (We can use KVC), and we can use them in the table titles
NSArray *parameterNames = [[NSArray alloc] initWithObjects: @"Name", @"Driver", @"Car", @"Track", nil];
//get the object for this row... (Name, Driver, Car, Track), and create a string to hold it's value..
id object = [session valueForKey: [parameterNames objectAtIndex: [indexPath row]]];
NSString *parameterValue;
NSLog(@"%@", [session name]);
//if this isn't the name row...
if(object != nil) {
//if the indexPath is greater than 0, object is not name (NSString)
if([indexPath row] > 0) {
parameterValue = [object name];
} else{
parameterValue = object;
}
} else{
//object doesn't exist yet... placeholder!
parameterValue = [@"Select a " stringByAppendingString: (NSString *)[parameterNames objectAtIndex: [indexPath row]]];
}
```
What I'm asking is... am I doing this right?

4,231,830 | 1 | 4,244,678 | null | 0 | 853 | I've created my own undo system for the RichTextBox whereby whenever you do something an undo action is added to a stack, and when you press undo, this action is undone.
This behavior works perfectly with all controls I've implemented it for, except for RichTextBoxes. I have reduced the system down to its simplest elements, where whenever you press delete, it adds the current selected text and its index to a stack, and when you undo this, it puts the text back at this index.
Here is the code with the simplest elements stripped out (like the actual reading of the text file):
```
// Struct I use to store undo data
public struct UndoSection
{
public string Undo;
public int Index;
public UndoSection(int index, string undo)
{
Index = index;
Undo = undo;
}
}
public partial class Form1 : Form
{
// Stack for holding Undo Data
Stack<UndoSection> UndoStack = new Stack<UndoSection>();
// If delete is pressed, add a new UndoSection, if ctrl+z is pressed, peform undo.
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Modifiers == Keys.None && e.KeyCode == Keys.Delete)
UndoStack.Push(new UndoSection(textBox1.SelectionStart, textBox1.SelectedText));
else if (e.Control && e.KeyCode == Keys.Z)
{
e.Handled = true;
UndoMenuItem_Click(textBox1, new EventArgs());
}
}
// Perform undo by setting selected text at stored index.
private void UndoMenuItem_Click(object sender, EventArgs e)
{
if (UndoStack.Count > 0)
{
// Save last selection for user
int LastStart = textBox1.SelectionStart;
int LastLength = textBox1.SelectionLength;
UndoSection Undo = UndoStack.Pop();
textBox1.Select(Undo.Index, 0);
textBox1.SelectedText = Undo.Undo;
textBox1.Select(LastStart, LastLength);
}
}
}
```
However if you select just the \n from one line, and more text below like this: , then press delete, and then undo, it seems to undo this \n character twice.

4,232,391 | 1 | 4,236,907 | null | 5 | 1,652 | I want to listen for continuous changes from CouchDB using jQuery - now this works:
```
http://localhost:5984/testdb/_changes?feed=continuous
```
which means that I get a new line of json every time there is a db update - but how do I read updates off this URL using jQuery?
I tried using this but it doesn't work:
```
$.ajax(
{
url : "http://localhost:5984/testdb/_changes?feed=continuous&callback=?",
dataType : 'json',
success : function(data)
{
alert(data.results.length);
}
});
```
: $.ajax calls the "success" function and returns immediately, it doesn't "poll" for changes.. (timeline column for ajax column in image below is 16ms)
And no, it isn't a cross-domain ajax problem - I can see in fireBug there is a response with the right number of elements
So any guidance/advice would be appreciated - it doesn't have to be jQuery - plain old javscript would do as well

I believe that I have already got almost everything right besides the text spacing and the colors:
I am not interested on the colors now, but the text spacing is really bothering me. For instance, have a look on the 'Ti' in 'Tijuca'. The two letters are really close together in the original image and I can't reproduce this feature.

Can I get rid of these using CSS ?
(Or what shall I use instead of "pre" tags? The text elements may contain HTML elements themeselves : which should be rendered, and should be shown literally as source-code: hence my initial choice with "pre" tags)

Is to use 'display:inline' for all PRE tags. (Previously I was only applying the 'display:inline' to the 'error' tags in the example above, and had forget to do the same for 'ok' pre tags.
