RichEdit prohibit copy to clipboard

I have become convinced to use CRichEdit for displaying and printing our reports.  My problem is that some of the reports contain financial/auditing data.  I'm concerned that a user could ^C an entire financial report, paste it to WordPad, and then alter the data.  It would NEVER work long term, but, even in the short term, it could be a real problem.

Is there a way to keep the user from performing a copy operation on a RichEdit control?

Thanks, rick

you have to derive your own control class, and override the PreTranslateMessage function:


BOOL CMyRichEdit::PreTranslateMessage(MSG* pMsg) 

{

 	// disable copy by mouse or keyboard

	switch( pMsg->message )

	{

	case WM_KEYDOWN:

		if ( pMsg->wParam==67 && GetKeyState(VK_CONTROL) )

			return true;

		break;

	case WM_RBUTTONDOWN:

		return true;

	}

	

	return CMyRichEdit::PreTranslateMessage(pMsg);

}
