如何让你的WinForm嵌入桌面

新一篇: SyntaxHighlighter part1

首先, 调用一些User32.dll的WinAPI函数

internal class User32
    ...{
        public const int SE_SHUTDOWN_PRIVILEGE = 0x13;

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

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

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

然后, 在WinForm里面

        public MainForm()
        ...{
            InitializeComponent();

            try
            ...{
                if (Environment.OSVersion.Version.Major < 6)
                ...{
                    base.SendToBack();

                    IntPtr hWndNewParent = User32.FindWindow("Progman", null);
                    User32.SetParent(base.Handle, hWndNewParent);
                }
                else
                ...{
                    User32.SetWindowPos(base.Handle, 1, 0, 0, 0, 0, User32.SE_SHUTDOWN_PRIVILEGE);
                }
            }
            catch (ApplicationException exx)
            ...{
                MessageBox.Show(this, exx.Message, "Pin to Desktop");
            }
        }

        private void MainForm_Activated(object sender, EventArgs e)
        ...{
            if (Environment.OSVersion.Version.Major >= 6)
            ...{
                User32.SetWindowPos(base.Handle, 1, 0, 0, 0, 0, User32.SE_SHUTDOWN_PRIVILEGE);
            }
        }

        private void MainForm_Paint(object sender, PaintEventArgs e)
        ...{
            if (Environment.OSVersion.Version.Major >= 6)
            ...{
                User32.SetWindowPos(base.Handle, 1, 0, 0, 0, 0, User32.SE_SHUTDOWN_PRIVILEGE);
            }
        }
