I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

i Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using
System.Windows.Forms.Application.Run(General)
General is a form but also a class, so I wonder what it the pros or cons of using :
System.Windows.Forms.Application.Run(General)
vs
Dim gen as general
System.Windows.Forms.Application.Run(gen)
In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable.

OK, in it's simpest terms, I have a custom object (all string Items) which I add to a list of those items. The list is declared as a global variable. One form updates the list, another contains a dataGridView (vs.net 3.5) that displays the list items. The view displays the correct data. For some reason, if I select a header in the dgv before it's populated, that's fine, but if I select it (click anywhere with the mouse) it bugs out with an Index = -1 error from the System.Windows.Forms. CurrencyManager.get_Item(Int32 index) bit.

I have been trying to figure out the source of error in my application. What this function (GetConcentrations()) is to display data from my database onto a DataGridView. The function is called in the PageLoad but works fine but when I call it in another Sub, I get this error.
Here is the code:
Private Sub GetConcentrations()
Dim conString As String = ConfigurationManager.ConnectionStrings("dbAsthmaConnectionString").ConnectionString
Me.dataAdapter = New SqlDataAdapter("Select * from tblConcentrations", conString)

[URL]The issue is as soon as I change the value of the text boxes it gives me an error and forces me to close the project.
The error is:Unable to cast object of type 'System.EventArgs' to type 'System.Windows.Forms.KeyPressEventArgs'.

I've just started learning VB.NET with VS 9.0; a small application I'm working on keeps returning an "A first chance exception of type System InvalidOperationException occurred in System Windows Forms dll" error from the Immediate Window. The application has almost zero functionality so far, it consists of a menu strip with:
File About
|Open
|Save
|Save As
|Quit
The only code I have written opens an Open File dialog, a Save As dialog, an About window with background sound and an OK button, and the Quit button which exits.
Since there is almost no code for me to search through, I can't understand why there would be an error. The program runs just fine when I'm debugging it too.

We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)
How to I enforce a coding practice?

Is it something dealing with the permissions set with the database server or something?
