PreTranslateMessage(), OnCancel()

[kumar_mk]

Dear members, i have a query, In my dialog box i have an Edit Control that takes numeric value, Now after typing the value in the edit box, i press RETURN key for some validation to take place, for this task i am handling the PreTranslateMessage() for the VK_RETURN message, Now the problem is when i highlight the CANCEL button (with tab button)in the dialog box and try to close the Dialog Box by pressing ENTER button it is not responding (the dialog box is not closing), the reason is obvious that since i am handling the PreTranslateMessage() it is not responding, but i also want the dialog to be closed when i hit the Enter button after highlighting the Cancel button, how can i accomplish this?? OR is there any other way to handle the RETURN key validation stuff than using PreTranslateMessage(), so that the Cancel button's original behaviour is not lost. Please Help!!!

thanx in advance kumar

The usual approach in MFC when overriding such functions for certain events is to call the base-class implementation of that function afterwards. You just do all Preprocessing you need, and then you call the base-class implementation and propagate its return value.

Along with the checking of VK_RETURN, check whether the handle is that of edit control. if( WM_KEYDOWN == pMsg->message ) { if( VK_RETURN == pMsg->wParam && m_edit.m_hWnd == pMsg->hwnd )// m_edit is the control variable of the edit control { // do ur computation return TRUE; } }
