i know 1 method of preventing mfc dialog closing when enter or esc keys pressed, i'd know more details of process , common alternative methods doing so. thanks in advance help. when user presses enter key in dialog 2 things can happen: the dialog has default control (see cdialog::setdefid() ). wm_command id of control sent dialog. the dialog not have default control. wm_command id = idok sent dialog. with first option, may happen default control has id equal idok. results same in second option. by default, class cdialog has handler wm_command(idok) call cdialog::onok() , virtual function, , default calls enddialog(idok) closes dialog. so, if want avoid dialog being closed, 1 of following. set default control other idok . set handler wm_command(idok) not call enddialog() . override cdialog::onok() , not call base implementation. about idcancel, similar there not equivalent setdefid() , esc key hardcoded. avoid dialog being closed: set han...
