 virtual BOOL PreTranslateMessage(MSG* pMsg)
 {
  if ((pMsg->message >= WM_KEYFIRST && pMsg->message <= WM_KEYLAST)
   && (pMsg->wParam != VK_RETURN && pMsg->wParam != VK_TAB && pMsg->wParam != VK_ESCAPE))
  {
   CWnd* pWnd = CWnd::GetFocus();
   if (pWnd && pWnd->IsKindOf(RUNTIME_CLASS(CXTPEdit)))
    return FALSE;
  }
  
  return Base::PreTranslateMessage(pMsg))
 }
