MFC Dialog Close Handler

[VFaul]

I created a dialog-type MFC app in VS 2005. I created a handler for the OK button so I can cleanup prior to exiting. However, if the user clicks the red X in the upper right of the dialog, my cleanup code is not executed. How do I create a handler for when the user quits via the X? Thanks

Clicking the x acts like the cancel button. You could clean up in a OnCancel() override as well as OnOk(). Mark

Which requires "cleanup" code to be in two spots. Why not do it in just one central spot?

If you want to account for all methods of dismissing the dialog (OK, Cancel, Alt+F4, "X"), handle the WM_DESTROY message.

I don't know...why not? That's why I wrote "You could ..." instead of "The only way to do it is ..."
