Creating a Transparent Hole Region in Different Shapes on Any Window

Environment: Visual C++ 6.0 Windows 9x, Windows NT 4.0 and Windows 2000

With this class you can make transparant (full access through hole) region in different shape on the most type of windows. Basically it is only one significant function in the class. This is most a funny way to use region like ellipse, rectangle, roundrect, circles and polygon. But i am sure that some of you can find a way to use it, for example in a screen saver. If you find another way to use it, please let me know!

    CMagicHole mag(GetDlgItem(IDC_BUTTON1)->GetSafeHwnd());
    mag.MakeHoleArea(CRect(4,4,100,60));
    the first time,the hole in the button is not transparent and we cannot see the word of "button1". why? even I add the UpdateWindow(), it does not take effect.
