Exception on Application.Exit()

Hello,

when my application shuts down via Application.Exit() I get a message box with the text ["unknown software exception" 0x80000003 on .....]. In the application I use DirectShow (via directshow.net) and managed DirectX. Besides that I start a tcp listener in a seperate thread but gracefully close it via thread.join(number of milliseconds).

This exception did not pop up 5 days ago. Does somebody know where I can look at when debugging or just a few hints where too look at in the internet or sdk

Thanks in advance, Armin

You can use the Debug Diagnostics Tool from the IIS Diagnostic Toolkit to capture a memory dump during a crash. But if you have the code - Run in debug and stop on first chance exceptions. That should allow you to break into the code that is causing the exception.
