Some clarification:
I am writing an embedded application. My class must be static (reside in the BSS), but at instantiation it ...

The issue....
Restricting construction of a class before some method gets called is going to be a losing battle in the constructor of a class that is instantiated before main()
One possible way is to instance the class first accessed.

If I have a nested loop scenario and I am stepping into it in debug mode. Ex:
for (int i = 0; i < listTest.Count; i++) { for (int j = 0; j < anotherList.Count; j++) { //Some logic that throws an exception } }
Is there a way for me to know the values...

First, you....
When the exception occurs, i and j should be the value at the time of the exception .
Place your breakpoint on the line within the catch.
Catch the exception and rethrow it.
Surround all the code inside the second loop with a try/catch block .

Why(); --> </script> </body>
If I understand things correctly, myInit is gonna get.
So you can't count on myFunction being run before anotherFunction for example.

Hi,
I am working on a project in ASP.NET MVC using C# 3.0.
I am using the Dundas Chart Control for OLAP. As the Dundas control does not directly support MVC it is used on a standard ASP.NET page with a codebehind file. This page is displayed in an iFrame...

I 'solved' this by creating an instance of the controller in the code-behind - in this project using a Spring.net IOC objects.xml... .
An "uggly" way could be to store the xml in a session or cache that you could access from both controllrs and aspx pages .

You could fire the screenshot from the frame when the it has gained focus:
class ScreenshotShooter implements FocusListener { public void focusGained( FocusEvent e ) { // smile // you may... .
You could add a delay the the thread that takes the screenshot .

I'm making a chat application that works with long-polling to emulate a "push" from server to client.

Of course you will also need to handle 502/503 responses, etc. .
Update:
Detecting timeouts on an XHR is actually complicated, since it's not built-in for some reason .
The browser should detect a timeout on an XHR and make another request .

You can use subqueries....
FROM info INNER JOIN media ON info.mid = media.id WHERE they navigate, then you're still going to hit the database to get the next item in whatever direction end instead.
To get the previous and next rows:
