X button in the Dialog MFC vc++

[Member_14575556]

I trying to put some custom functionality when x button is clicked for a specific dialog. There is no cancel button in this dialog. What would be the best way to do this? Thank you.

Can you handle the WM_CLOSE message ?

I'd rather be phishing!

Override the dialog's OnCancel() method.

Thanks, this is exactly what I wanted. :)

While OnClose() does get called when dismissing the dialog using the X or Alt+F4, it will not get called when dismissing the dialog using Esc or clicking the Cancel button (if one is present). This may not be an issue for your specific dialog, however.
