如何将 Windows 窗体应用程序 (C++) 设置为具有 Aero/Glass 背景？

Question

我正在使用 Visual Studio 2010 Pro 用 C++ 创建 Windows 窗体应用程序。我想创建一个透明背景，即使用 Aero Glass 效果，类似于它围绕 Windows 照片查看器中 UI 底部的方式。此时，我已经查看了所有功能，虽然您可以更改颜色和不透明度，但这并不完全是我想要的。我想要那种漂亮的模糊玻璃效果。

我从 Visual Studio 提供的模板代码开始这个项目，所以我没有太多可以链接的内容。我刚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。我对我的缺乏投入表示歉意，我对 Windows UI 编程还很陌生；我希望我可以添加更多信息。为了简单起见，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.

下面是一些 C# 代码，演示了如何执行此操作： CodeProject

另外，请确保启用桌面合成时不要扩展框架，否则您将遇到问题。
