I need to override the behaviour of my CDialog-derived class when Enter or Esc key is pressed, but this event is not caught in CDialog::OnKeyDown(), and, although these keys generally hide the dialog, CWnd::OnWindowShow() is never called either. What message handler should I look for?

u can override OnOk() for Enter & OnCancel()for Esc.This look like
   void CMyDialog::OnOK()
   {
   }
   void CMyDialog::OnCancel()
   {
   }
this can be done by simply add a two methods in class wizard as in the above

Or you can look at PreTranslateMessage():

BOOL CYourDlg::PreTranslateMessage(MSG* pMsg)
{
  if (pMsg->message == WM_KEYDOWN && 
      (pMsg->wParam == VK_ESC || pMsg->Param == VK_ENTER)
    return TRUE;

  return CDialog::PreTranslateMessage(pMsg); // Or parent class if not CDialog
}

Good Luck,
Steve

Thanks, this looks like the best code that would work for all cases.
