Did you remove the call to the CDialog implementation in OnCancel?

Please check out the reply in your previous thread.. It has a sample implementation. It might help you... if not, do not know where the prob is..

I normally use PreTranslateMessage to prevent unwanted key presses

BOOL CDialogClass::PreTranslateMessage(MSG* pMsg)
{
  // Have we pressed a key
  if (pMsg->message == WM_KEYDOWN)
  {
    // We only want to ignore the ESC
    if (pMsg->wParam == VK_ESCAPE)
    {
      return TRUE;
    }
  }

return CDialog::PreTranslateMessage(pMsg);
}

If you only want to filter the physical keyboard key, look at Anthonys answer below.

button work when you override OnCancel() you have to override OnClose(). In the override call CDialog::OnCancel(). The default behaviour of OnClose() is to call your overridden OnCancel() which you have told to do nothing. Do not override PreTranslateMessage(). That is just the lazyman's way of hacking things together.
