利用C++中CreatePolygonRgn、CreateRoundRectRgn、CreateRoundRectRgn、CreateRectRgn或CreateEllipticRgn函数，建立透明窗体示例程序-CreatePolygonRgn using C, CreateRoundRectRgn, CreateRoundRectRgn. CreateRectRgn or CreateEllipticRgn function, transparent Window sample program

调用CreatePolygonRgn（）自定义函数实现的多边形窗口-Call CreatePolygonRgn () custom function to achieve the Polygon

利用C++中CreatePolygonRgn,CreateRoundRectRgn,CreateRoundRectRgn,()
