鼠标移动之hook学习

今天一直到晚上4点才可以上网，晕死偌大的一个科教城，怎么就那么不济呢，，呵呵没有bs
的意思的饿。
今天不能上网只能将以前的资料整理下上次说学习 hook的，还是有点看不太懂，但是貌似我的工作又向前面进了一步了。下面是我在网络上找到的一个代码段。我直接将它用在我的程序里面，然后直接调用，我的神啊，看了一个上午只看出一个大概，感觉还可以。

这个代码我是一个都没有动的直接就用了，下面我就自己写了点东西吧它连接进去。

using System;
using System.Collections.Generic;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;


namespace hook鼠标控制
{
    public partial class Form1 : Form
    {
        hook鼠标控制.MouseHook mouse;
        public Form1()
        {
            InitializeComponent();
            mouse = new MouseHook();
            mouse.OnMouseActivity += new MouseEventHandler(this.mouse_OnMouseActivity);

        }

        [Flags]
        enum MouseEventFlag : uint
        {
            Move = 0x0001,
            LeftDown = 0x0002,
            LeftUp = 0x0004,
            RightDown = 0x0008,

            Wheel = 0x0800,
            VirtualDesk = 0x4000,
            Absolute = 0x8000
        }


        [DllImport("user32.dll ", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern bool SetDoubleClickTime(uint  uInterval);

        [DllImport("user32.dll")]
        static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);

        [DllImport("user32.dll")]
        static extern bool SetCursorPos(int X, int Y);


        private void button1_Click(object sender, EventArgs e)
        {
            //mouse.Start();
            SetCursorPos(Convert.ToInt16(this.lb_x.Text.Trim()), Convert.ToInt16(this.lb_y.Text.Trim()));

            mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
            mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
        }

        private  void mouse_OnMouseActivity(object sender, MouseEventArgs e)
        {
            this.lb_x.Text  = e.X.ToString ();
            this.lb_y.Text  = e.Y.ToString ();
            this.lb_z.Text = e.Button.ToString();

            //MessageBox.Show(e.X.ToString());
            //throw new Exception("The method or operation is not implemented.");
        }

        private void button2_Click(object sender, EventArgs e)
        {
            //bool t = false;
            //t = SetDoubleClickTime(500);
            //if (t)
            //{
            //    MessageBox.Show("设立成功!");
            //}
            //mouse.Stop();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }
}

这样我就做到了我的效果了，但是具体还没有实现。我只想那么做看下，估计应该可以实现。
