Function call at the end of an application

Is there a way for me to determine which functions/messages are called at the end of an application? That is, I have a memory leak which I'm trying to find and I want to see where the problem is.

You can try to run the program into debugging mode, using the tools that Visual Studio provides for memory leaks detection.

Pls read and (for MFC).

The object dumps & dumps statistics are pretty effective.

The memory leak might be caused by a line of code right at the application start assigning memory which isn't then released.   Don't make ANY assumptions about where it might be.

for an SDI or MDI mfc application the program runs nearly all time in CWinThread::Run where the message loop was performed. you could provide an overload of CWinApp::ExitInstance in your application class which would be called as very last function by the mfc framework.

for a dialog-based mfc application the program exits in InitInstance function of your application class after DoModal call.

Hi Andy

I understand what you mean about memory that isn't released. If this is the case how can I find the problem line?

I'd look at the links provided by incerc, they seem to be relevant.

Look at the output window, it should say what type of object was assigned but not being freed and more info about it.
