Unhandled exception when application exits

[pjc300]

When the application is exiting in either debug or release mode I am getting an unhandled exception, but i have no clue where to start looking for it (I've picked up the code from someone).

The following stack trial in debug mode is shown below:

The ~CApplicationProfile()is empty.
I believe it may be something to do with the destruction of strings but i don't know where to start looking

Is there any configuration or means in visual studio.NET 2003 where I can get a better idea of the source of the exception.

This happened to me once when I was using Winsock and forgetting to call WSACleanup() before the program exited. Since you didn't say what your program was using, I don't know if this kind of thing could apply, but make sure that you aren't initializing something like that without cleaning it up. Then again, that was in a win32 app - in MFC there are more possible causes for this kind of thing and they can be harder to locate.
