C#如何实现WPF程序窗口当用户使用Win+D快捷键后，不让窗体实现最小化操作？

Question

C#如何实现WPF程序窗口当用户使用Win+D快捷键后，不让窗体实现最小化操作？在网上看到一些答案，都会使用SetParent和FindWindow两个系统API，但是我在Window_Load事件里面写的时候，当程序运行后窗口打不开了？？？希望各位能帮我解决Win+D不会把C#程序里面的窗口最小化。

Answer 1

Answer 2

[DllImport("User32.dll", EntryPoint = "SetParent", SetLastError = true)]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

[DllImport("User32.dll", EntryPoint = "FindWindow", SetLastError = true)]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

public Window1(){

this.SourceInitialized += (sender, e) =>
            {
                this._hwndSource = PresentationSource.FromVisual((Visual)sender) as HwndSource;
                this._handle = this._hwndSource.Handle;
            };

this.Load+=this.Window1_Load;

}

Window1_Load(object sender,EventArgs e){

         SetParent(this._handle , FindWindow("Progman", "Program Manager"));

}

Answer 3

Program Manager是一个什么样的程序？

不管怎样试试这个方法： 

1. 将Window.WindowStyle 设为 WindowStyle.None

2. 在右上角自己定义三个button。

3. 设置一个全局变量，表示是否是自定义的这个button按下。

4. 处理StateChanged事件：先判断flag:

        private bool flag;
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            flag = true;
            this.WindowState = System.Windows.WindowState.Minimized ;
        }

        private void Window_StateChanged(object sender, EventArgs e)
        {
            if (this.WindowState == System.Windows.WindowState.Minimized)
            {
                if (flag == false)
                {
                    this.WindowState = System.Windows.WindowState.Normal;
                }
            }
            else
                flag = false;
        }

5. Set the topmost to true: http://msdn.microsoft.com/en-us/library/system.windows.window.topmost.aspx

Answer 4

最简单的办法是屏蔽windows键吧应该，为什么搞这么复杂呢，不懂！

Answer 5

你说的有道理，但是我也试过了，如果屏蔽Win键，那么所有的程序都不会最小化。但我想要的是像QQ那样，只有自己的程序不最小化，而其他正在运行的程序还必须最小化。
