N.B. the standard MB_OK message box's OK button is really a Cancel button behind the scenes - that is why you can use the [X] button or the <esc> key to dismiss it.

DWORD dwRetValue = MessageBox("Hi there","Hello",MB_OK);
switch(dwRetValue)
{
case IDCANCEL:
    AfxMessageBox("Cancel was selected");
    break;
case IDOK:
    AfxMessageBox("OK was selected");

but what if a user points out the extracted exe and copies it then the whole purpose is simply defeated.
