c#写的热键注册程序

玩网页游戏挂机，又不想让别人看见你电脑的运行。所以写了个后台运行的程序。

先谁HotKey注册类，用来调用com组件来显示与隐藏窗体：

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace ntsvs
{
    static class Hotkey
    {
        //系统api#region 系统api
        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool RegisterHotKey(IntPtr hWnd, int id, HotkeyModifiers fsModifiers,Keys vk);

        [DllImport("user32.dll")]
        static extern bool UnregisterHotKey(IntPtr hWnd, int id);

        /**//// <summary>
        /// 注册快捷键
        /// </summary>
        /// <param name="hWnd">持有快捷键窗口的句柄</param>
        /// <param name="fsModifiers">组合键</param>
        /// <param name="vk">快捷键的虚拟键码</param>
        /// <param name="callBack">回调函数</param>
        public static void Regist(IntPtr hWnd, HotkeyModifiers fsModifiers, Keys vk, HotKeyCallBackHanlder callBack)
        {
            int id = keyid++;
            if (!RegisterHotKey(hWnd, id, fsModifiers, vk))
                throw new Exception("regist hotkey fail.");
            keymap[id] = callBack;
        }

        /**//// <summary>
        /// 注销快捷键
        /// </summary>
        /// <param name="hWnd">持有快捷键窗口的句柄</param>
        /// <param name="callBack">回调函数</param>
        public static void UnRegist(IntPtr hWnd, HotKeyCallBackHanlder callBack)
        {
            foreach (KeyValuePair<int, HotKeyCallBackHanlder> var in keymap)
            {
                if (var.Value == callBack)
                    UnregisterHotKey(hWnd, var.Key);
            }
        }

        /**//// <summary>
        /// 快捷键消息处理
        /// </summary>
        public static void ProcessHotKey(System.Windows.Forms.Message m)
        {
            if (m.Msg == WM_HOTKEY)
            {
                int id = m.WParam.ToInt32();
                HotKeyCallBackHanlder callback;
                if (keymap.TryGetValue(id, out callback))
                {
                    callback();
                }
            }
        }

        const int WM_HOTKEY = 0x312;
        static int keyid = 10;
        static Dictionary<int, HotKeyCallBackHanlder> keymap = new Dictionary<int, HotKeyCallBackHanlder>();

        public delegate void HotKeyCallBackHanlder();
    }

    enum HotkeyModifiers
    {
        MOD_ALT = 0x1,
        MOD_CONTROL = 0x2,
        MOD_SHIFT = 0x4,
        MOD_WIN = 0x8
    }

}

然后是主窗体formMain formmain里添加了一个webBrowiser控件，一个textbox控件，一个button控件。在webBrowiser里可以登录到页游的网址，按快捷键就可以隐藏网页了。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace ntsvs
{
    public partial class Form1 : Form
    {
        bool isVisible = false;
        public Form1()
        {
            InitializeComponent();
            //注册热键Shift+S，Id号为100。HotKey.KeyModifiers.Shift也可以直接使用数字4来表示。
            Hotkey.Regist(this.Handle, HotkeyModifiers.MOD_ALT, Keys.P, Test3);//最大化窗口
            Hotkey.Regist(this.Handle, HotkeyModifiers.MOD_ALT, Keys.B, Test2);//最小化
            Hotkey.Regist(this.Handle, HotkeyModifiers.MOD_ALT, Keys.L, Test1);//还原
            Hotkey.Regist(this.Handle, HotkeyModifiers.MOD_ALT, Keys.A, Test0);//隐藏
            Test0();
        }

        //0-隐藏窗口
        void Test0()
        {
            this.Activate();
            Class1.ShowWindowAsync(this.Handle, 0);
        }
        //1-还原窗口
        void Test1()
        {
            this.Activate();
            Class1.ShowWindowAsync(this.Handle, 1);
        }
        //2-最小化窗口，
        void Test2()
        {
            this.Activate();
            Class1.ShowWindowAsync(this.Handle, 2);
        }
        //3-最大化窗口,
        void Test3()
        {
            this.Activate();
            Class1.ShowWindowAsync(this.Handle, 3);
        }

        private void Form1_Shown(object sender, EventArgs e)
        {
            this.Visible = isVisible;
        }

        ///
        /// 监视Windows消息
        /// 重载WndProc方法，用于实现热键响应
        ///
        ///
        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            Hotkey.ProcessHotKey(m);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                this.webBrowser1.Url = new Uri(textBox1.Text);
                this.webBrowser1.Update();
            }
            catch { }
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            try
            {
                Hotkey.UnRegist(this.Handle, Test3);
                Hotkey.UnRegist(this.Handle, Test2);
                Hotkey.UnRegist(this.Handle, Test1);
                Hotkey.UnRegist(this.Handle, Test0);
                webBrowser1.Stop();
                webBrowser1.Dispose();
                Environment.Exit(0);
            }
            catch { }
        }
    }
}
