如何在C#中实现窗口的自动隐藏

[popomark18]

我想用C#编写一个类似于Visual Studio中的解决方案资源管理器那样的窗口，可以实现停靠、自动隐藏等功能，不知道如何实现，望大家多帮忙。

有个目前已经编写好了商业软件控件，DotNetBar
你可以去搜索一些，有破解版本。

参考如下代码：

using System.Runtime.InteropServices;

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    [DllImport("user32.dll")]
    public static extern IntPtr GetDesktopWindow();

    protected override CreateParams CreateParams
    {
        get
        {
            const int WS_EX_TOPMOST = 8; 
            base.CreateParams.Parent = GetDesktopWindow();
            base.CreateParams.ExStyle |= WS_EX_TOPMOST;
            return base.CreateParams;
        }
    }
    AnchorStyles anchors;
    const int OFFSET = 2;
    protected override void WndProc(ref Message m)
    {
        const int WM_MOVING = 534; 
        switch (m.Msg)
        {
            case WM_MOVING: // 窗体移动的消息，控制窗体不会移出屏幕外
                int left = Marshal.ReadInt32(m.LParam, 0);
                int top = Marshal.ReadInt32(m.LParam, 4);
                int right =Marshal.ReadInt32(m.LParam, 8);
                int bottom =Marshal.ReadInt32(m.LParam, 12);
                left = Math.Min(Math.Max(0, left),
                    Screen.PrimaryScreen.Bounds.Width - Width);
                top = Math.Min(Math.Max(0, top),
                    Screen.PrimaryScreen.Bounds.Height - Height);
                right = Math.Min(Math.Max(Width, right),
                    Screen.PrimaryScreen.Bounds.Width);

                Marshal.WriteInt32(m.LParam, 8, right);
                Marshal.WriteInt32(m.LParam, 12, bottom);
                anchors = AnchorStyles.None;

        }
        base.WndProc(ref m);
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        timer1.Enabled = false;
        timer1.Interval = 200;
        TopMost = true;
    }

    [DllImport("user32.dll")]
    public static extern IntPtr WindowFromPoint(Point Point);
    [DllImport("user32.dll")]

    {
        
        IntPtr vHandle = WindowFromPoint(Control.MousePosition);
        while (vHandle != IntPtr.Zero && vHandle != Handle)
            vHandle = GetParent(vHandle);
        if (vHandle == Handle) // 如果鼠标停留的窗体是本窗体，还原位置
        {
            if ((anchors & AnchorStyles.Left) == AnchorStyles.Left) Left = 0;
            if ((anchors & AnchorStyles.Top) == AnchorStyles.Top) Top = 0;

        }
        else // 隐藏起来
