C#怎么把窗体设在壁纸之上桌面图标之下

 

            
IntPtr P = FindWindow("Progman", "Program Manager");
P = FindWindowEx(P, IntPtr.Zero, "SHELLDLL_DefView", null);
P = FindWindowEx(P, IntPtr.Zero, "SysListView32", null);
SetParent(FrmName, P);

在网上找到的这个还是会覆盖桌面图标！
等待高人指点

      [DllImport("user32.dll", CharSet = CharSet.Auto)]
      public static extern IntPtr GetWindowDC(IntPtr hWnd);
      /// <summary>

      [DllImport("user32.dll", SetLastError = true)]
      static extern IntPtr SetParent(IntPtr child, IntPtr newParent);

      private void Form1_Load(object sender, EventArgs e)
      {

         IntPtr P = FindWindow("Progman", "Program Manager");
         IntPtr shellHandle = FindWindowEx(P, IntPtr.Zero, "SHELLDLL_DefView", null);
         IntPtr viewHandle = FindWindowEx(shellHandle, IntPtr.Zero, "SysListView32", null);

         SetParent(this.comboBoxTreeView1.Handle, viewHandle);

      }


我试了下确实没法放在图标下一层 估计是控件窗体的handle没找对

Answer 2

你的窗口是桌面的子窗口，无法设置在父窗口之下。
