如何设置Windows窗体应用程序(c++)有一个Aero/Glass背景

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，也就是说，使用Aero Glass效果，类似于Windows Photo Viewer中围绕UI底部的方式。在这一点上，我已经浏览了所有的功能，虽然你可以改变颜色和不透明度，但这并不是我想要的。我想要那种模糊的玻璃效果。

我是从Visual Studio提供给你的模板代码开始这个项目的，所以我真的没有太多要链接的。我只是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。我很抱歉我缺乏输入，我对Windows UI编程相当陌生;我希望我能提供更多的信息。为简单起见，下面是Form1.h代码:

#pragma once

namespace Secret { //my project's name is "Secret"
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
/// <summary>
/// Summary for Form1
/// </summary>
public ref class Form1 : public System::Windows::Forms::Form
{
public:
    Form1(void)
    {
        InitializeComponent();
        //
        //TODO: Add the constructor code here
        //
    }
protected:
    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    ~Form1()
    {
        if (components)
        {
            delete components;
        }
    }

谢谢你所有的帮助!我很感激。

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

下面是一些c#代码来演示如何做到这一点:

另外，请确保在启用桌面合成时不要扩展框架，否则会遇到问题。
