Intercepting ALT-F4 !

How can I intercept the ALT-F4 sequence for a dialog box and for a MDI application ?

When the user press ALT-F4, a dialog must appear for confirmation. If the user press YES then close application. If the user press NO then do nothing.

Hi mike_marquet,

Add a WM_CLOSE message handler to your window (either the dialog or the mainframe) and there do something like this:

void CMainFrame::OnClose()
 if ( AfxMessageBox( "Really want to close ?", MB_YESNO ) != IDYES )

hope that helps,
