【CSharp】 winform嵌入桌面，win+d也不最小化

作者:x123jing / 发布于2014/2/24/ 584

[DllImport("user32.dll", EntryPoint = "SetParent")]
public static extern int SetParent(int hWndChild, int hWndNewParent);

[DllImport("user32.dll", EntryPoint = "FindWindow")]
public static extern int FindWindow(string lpClassName, string lpWindowName);

public Form1()
{
InitializeComponent();
SetParent(this.Handle.ToInt32(), FindWindow("Progman", "Program Manager"));

}



以上在win7以下系统基本正常，在win7里会出现界面不出的现像。

下面这段可用，进行了系统判断。

    private const int SE_SHUTDOWN_PRIVILEGE = 0x13;

    [DllImport("user32.dll")]
    public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

    [DllImport("user32.dll")]
    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    [DllImport("user32.dll")]
    public static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);

    public djradio()
    {
      InitializeComponent();
      MessageBox.Show(Environment.OSVersion.Version.Major.ToString());
      try
      {
        if (Environment.OSVersion.Version.Major<6)
        {
          base.SendToBack();

          IntPtr hWndNewParent = FindWindow("Progman", "Program Manager");
          SetParent(base.Handle, hWndNewParent);
        }
        else
        {
          SetWindowPos(base.Handle, 1, 0, 0, 0, 0, SE_SHUTDOWN_PRIVILEGE);
        }
      }
      catch (ApplicationException exx)
      {
        MessageBox.Show(this, exx.Message, "Pin to Desktop");
        //throw;
      }
    }

    private void djradio_Activated(object sender, EventArgs e)
    {
      if (Environment.OSVersion.Version.Major >= 6)
      {
        SetWindowPos(base.Handle, 1, 0, 0, 0, 0, SE_SHUTDOWN_PRIVILEGE);
      }

    }

    private void djradio_Paint(object sender, PaintEventArgs e)
    {
      if (Environment.OSVersion.Version.Major >= 6)
      {
        SetWindowPos(base.Handle, 1, 0, 0, 0, 0, SE_SHUTDOWN_PRIVILEGE);
      }
    }
