void CxxxxDlg::OnNcPaint() 
{
	// TODO: Add your message handler code here
	CDialog::OnNcPaint();
    CWindowDC dc(this);
    CRect rcWin;
    GetWindowRect(rcWin);
    rcWin.OffsetRect(-rcWin.TopLeft());
    CBrush br;
	br.CreateSolidBrush(RGB(255,0,0));
// 3 pixels
	dc.FrameRect(rcWin, &br);
	rcWin.DeflateRect(1,1);
	dc.FrameRect(rcWin, &br);
	rcWin.DeflateRect(1,1);
	dc.FrameRect(rcWin, &br);
	// Do not call CDialog::OnNcPaint() for painting messages
