Catching a closing dialog window

Is there a message that I can handle in a dialog box that gets called regardless of how the dialog is closed? I need to save changed data whether the user clicks OnOK, OnCancel, or the menu "X" button or presses the ESC key.

Thanks

Wm_destroy

WM_DESTROY should do it

Thanks guys.

The VS wizard created OnDestroy for me and the comments say to put my code after the call to CDialog::OnDestroy(). Is the window still valid at that point, or should I avoid writing anything to the text controls?

Wouldn't it be faster to write the code and check than to post here and wait for a response?
