How do I override "OnExit"

[panioti]

What happens when operator clicks File->Exit, or hits the "X" button in upper-rt corner (whats the name of this X function).

I want to do some cleanup before allowing exit to proceed. Is there a message that can be intercepted.

The are several places that might be used for cleanup. Which is the most suitable depends on you application, and the scope of the clean-up.

If it's a doc-view, then it could be in the document's DeleteContents method, or destructor. Or in the view's OnDestroy or destructor.

It could be in the CWinApp's ExitInstance, or destructor.

I am not sure, but try it with WM_DESTROY message.

CWinApp ExitInstance is what I was looking for, thanks.
