VC.NET源代码创建一个圆角窗口，椭圆形窗口，创建非矩形的窗口，虽然不是常规的窗口类型，但也算“规则”窗口吧，因为除了四角是圆的之外，其余地方与标准的矩形窗口没什么不同，只可惜牺牲了窗口右下角的拖放功能，不能按住鼠标实现拖动了，只能一点一点改边宽度后再改变高度，这样可把窗口拉大或缩校 -VC.NET source code to create a rounded window, oval window, create a non-rectangular windows, though not a conventional window type, but also considered " the Rules"　window, because in addition to the four corners are rounded, the other place with the standard rectangular window is no different, but unfortunately at the expense of the lower right corner of the window and drop feature, you can not hold down and drag the mouse to achieve, can only change a little bit and then change the height of the edge width, which can widen or shrink the window School
