如何將 Windows Forms 應用程序（C++）設置為具有航空/玻璃背景？

Question

我正在使用 Visual Studio 2010 Pro 在 C++ 中創建 Windows Forms 應用程序。 我想創建一個透明背景，即使用 Aero Glass 效果，類似於它在 Windows Photo Viewer 中圍繞 UI 底部的方式。 在這一點上，我已經瀏覽了所有功能，雖然您可以更改顏色和不透明度，但這並不是我想要的。 我想要那種漂亮的模糊玻璃效果。

我從 Visual Studio 為您提供的模板代碼開始了這個項目，所以我並沒有太多要鏈接的東西。 我剛剛從工具箱中添加了一些項目並將它們鏈接到 Form1.h 文件中的函數。 我為我缺乏輸入而道歉，我對 Windows UI 編程很陌生； 我希望我可以添加更多信息。 為簡單起見，這里是 Form1.h 代碼：

感謝您的任何幫助。 我很感激。

您正在尋找的是 DWM（桌面 Window 管理器）API，尤其是 function DwmExtendFrameIntoClientrea

這是一些 C# 代碼，演示了如何執行此操作： CodeProject

另外，請確保在啟用桌面合成時不要擴展框架，否則會遇到問題。
