MFC CRichEditCtrl::PreTranslateMessage

Question

Hi,

I subclassed CRichEditCTrl and in PreTranslateMessage I am handling ctrl+x. On ctrl+x I am confirming the user whether to delete text

case 88: //ctrl+x
if(IDNO==AfxMessageBox(_T("Do you want to delete selected text?"),MB_YESNO|MB_ICONQUESTION)) return true;
break;

If I execute AfxMessageBox, the PreTranslateMessage receives message WM_CHAR with char x right after ctrl+x and in the richeditctrl character x is getting typed.. If I am not calling AfxMessageBox on ctrl+x, the PreTranslateMessage does not receive the message WM_CHAR with char x.

How to avoid PreTranslateMessage receiving WM_CHAR with char x ? I need to confirm with the user whether to delete the text or not?

Thanks

Give this a try -

 BOOL CMyRichEditCtrl::PreTranslateMessage(MSG* pMsg)
 {
   // TODO: Add your specialized code here and/or call the base class

   if (pMsg->message == WM_KEYDOWN  && pMsg->wParam == 0x58 && (::GetKeyState(VK_CONTROL) & 0x8000) != 0)
   {
     if (AfxMessageBox(_T("Delete Text?"), MB_YESNO) == IDYES)
           PostMessage(WM_CUT);

     return TRUE;
   }

   return CRichEditCtrl::PreTranslateMessage(pMsg);
 }
