Question

我正在使用Visual Studio 2010 Pro在C ++中创建Windows窗体应用程序。我想创建一个透明的背景，即使用Aero Glass效果，类似于它在Windows Photo Viewer中围绕UI底部的方式。在这一点上，我已经浏览了所有功能，虽然你可以改变颜色和不透明度，但这并不是我正在寻找的。我想要那种漂亮的模糊玻璃效果。

我是从Visual Studio为您提供的模板代码启动此项目的，因此我没有太多要链接的内容。我刚从工具箱中添加了一些项目，并将它们链接到Form1.h文件中的函数。我为缺乏输入而道歉，我对Windows UI编程很新;我希望我能添加更多信息。为简单起见，这里是Form1.h代码：

感谢您的帮助！我很感激。

您正在寻找的是DWM（桌面窗口管理器）API，尤其是函数DwmExtendFrameIntoClientArea。

以下是一些C＃代码，演示了如何执行此操作：CodeProject

此外，请确保在启用桌面合成时不延长框架，或者run into problems。
