void CMyDialog::OnPaint()
{
    CWnd* pWnd = GetDlgItem(IDC_STATIC1);     // IDC_STATIC1 specified
                                              //  in the dialog editor
    CDC* pControlDC = pWnd->GetDC();    pWnd->Invalidate();
    pWnd->UpdateWindow();
    pControlDC->SelectStockObject(BLACK_BRUSH);
    pControlDC->Rectangle(0, 0, 10, 10);      // black square bullet
    pWnd->ReleaseDC(pControlDC);
}
