Odd Problem In VB.Net, Please Help

[Guest]

If anything occurs (open a program, move an application window, switch between applications, click the start buttong) while my application is running, a null reference exception is thrown. The application is very simple, all it does it retrieve the contents of a local directory, delete them, retrieve the contents of a remote directory and copy them, any ideas what would cause this? I can post the code if it is needed, All I use is Directory.GetDirectories, Directory.GetFiles, Directory.Delete, Directory.Copy, File.Copy, and File.Delete.

Please post the complete exception text + callstack.

Sorry, I figured it out, I am trying to get the text to refresh so I used activeform.update instead of just using the update method... That was causing the crash...

I am still having a problem getting the form to update after moving it. When I move the form it stops updating, and if I click it, it says that it is not responding. Is there any way to pause the execution of the application so that the form can update?

Can you throw in some Application.DoEvents into your looping?
