最近研究热键枚举，稍微总结一下，以后继续补充：

Winform程序全局热键

Winform程序全局热键一般采取的是，调用windows api的情势，主要是通过面下的四个函数

            /// <summary> /// 如果函数行执胜利，回返值不为0。 /// 如果函数行执失败，回返值为0。要失掉扩展错误信息，调用GetLastError。.NET方法:Marshal.GetLastWin32Error() /// </summary> /// <param name="hWnd">要定义热键的口窗的句柄</param> /// <param name="id">定义热键ID（不能与其它ID复重） </param> /// <param name="fsModifiers">识标热键否是在按Alt、Ctrl、Shift、Windows等键时才会效生</param> /// <param name="vk">定义热键的内容,WinForm中可以应用Keys枚举转换， /// WPF中Key枚举是不确正的,应当应用System.Windows.Forms.Keys枚举，或者自定义确正的枚举或int常量</param> /// <returns></returns> [DllImport("user32.dll", SetLastError = true)]public static extern bool RegisterHotKey(IntPtr hWnd,UInt32 id,UInt32 fsModifiers,UInt32 vk);

/// <summary>             /// 取消册注热键             /// </summary>             /// <param name="hWnd">要取消热键的口窗的句柄</param>             /// <param name="id">要取消热键的ID</param>             /// <returns></returns>             [DllImport("user32.dll", SetLastError = true)]             public static extern bool UnregisterHotKey(             IntPtr hWnd,             UInt32 id             );

/// <summary>             /// 向全局子原表添加一个符字串，并回返这个符字串的一唯识标符,胜利则回返值为新创建的子原ID,失败回返0             /// </summary>             /// <param name="lpString"></param>             /// <returns></returns>             [DllImport("kernel32", SetLastError = true)]             public static extern UInt32 GlobalAddAtom(string lpString);

/// <summary>             /// 从全局子原表删除指定一个符字串，并回返这个符字串的一唯识标符,失败回返0             /// </summary>             /// <param name="nAtom"></param>             /// <returns></returns>             [DllImport("kernel32", SetLastError = true)]             public static extern UInt32 GlobalDeleteAtom(UInt32 nAtom);

还有一个帮助类，志标户用否是册注了含有win ctrl shift等特别键的快捷式方

/// <summary> /// 定义了帮助键的名称（将数字转变为符字以便于记忆，也可去除此枚举而直接应用数值） /// </summary>public enum KeyFlags{MOD_NONE = 0x0,MOD_ALT = 0x1,MOD_CONTROL = 0x2,MOD_SHIFT = 0x4,MOD_WIN = 0x8}

贴上部全代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Collections;namespace luolunz
{public delegate void HotkeyEventHandler(int hotKeyID);public class HotkeyHelper : IMessageFilter{public event HotkeyEventHandler OnHotkey;public enum KeyFlags{MOD_NONE=0x0,MOD_ALT = 0x1,MOD_CONTROL = 0x2,MOD_SHIFT = 0x4,MOD_WIN = 0x8   }class NativeMethods{private NativeMethods() { }#region WIN32 API/// <summary> /// 如果函数行执胜利，回返值不为0。 /// 如果函数行执失败，回返值为0。要失掉扩展错误信息，调用GetLastError。.NET方法:Marshal.GetLastWin32Error() /// </summary> /// <param name="hWnd">要定义热键的口窗的句柄</param> /// <param name="id">定义热键ID（不能与其它ID复重） </param> /// <param name="fsModifiers">识标热键否是在按Alt、Ctrl、Shift、Windows等键时才会效生</param> /// <param name="vk">定义热键的内容,WinForm中可以应用Keys枚举转换， /// WPF中Key枚举是不确正的,应当应用System.Windows.Forms.Keys枚举，或者自定义确正的枚举或int常量</param> /// <returns></returns> [DllImport("user32.dll", SetLastError = true)]public static extern bool RegisterHotKey(IntPtr hWnd,UInt32 id,UInt32 fsModifiers,UInt32 vk);/// <summary> /// 取消册注热键 /// </summary> /// <param name="hWnd">要取消热键的口窗的句柄</param> /// <param name="id">要取消热键的ID</param> /// <returns></returns> [DllImport("user32.dll", SetLastError = true)]public static extern bool UnregisterHotKey(IntPtr hWnd,UInt32 id);/// <summary> /// 向全局子原表添加一个符字串，并回返这个符字串的一唯识标符,胜利则回返值为新创建的子原ID,失败回返0 /// </summary> /// <param name="lpString"></param> /// <returns></returns> [DllImport("kernel32", SetLastError = true)]public static extern UInt32 GlobalAddAtom(string lpString);/// <summary>/// 从全局子原表删除指定一个符字串，并回返这个符字串的一唯识标符,失败回返0/// </summary>/// <param name="nAtom"></param>/// <returns></returns>[DllImport("kernel32", SetLastError = true)]public static extern UInt32 GlobalDeleteAtom(UInt32 nAtom);/// <summary> /// 定义了帮助键的名称（将数字转变为符字以便于记忆，也可去除此枚举而直接应用数值） /// </summary>public enum KeyFlags{MOD_NONE = 0x0,MOD_ALT = 0x1,MOD_CONTROL = 0x2,MOD_SHIFT = 0x4,MOD_WIN = 0x8}#endregion}Hashtable keyIDs = new Hashtable();IntPtr hWnd;public HotkeyHelper(IntPtr hWnd){this.hWnd = hWnd;Application.AddMessageFilter(this);}public UInt32RegisterHotkey(Keys Key, KeyFlags keyflags){UInt32 hotkeyid = NativeMethods.GlobalAddAtom(System.Guid.NewGuid().ToString());NativeMethods.RegisterHotKey((IntPtr)hWnd, hotkeyid, (UInt32)keyflags, (UInt32)Key);keyIDs.Add(hotkeyid, hotkeyid);return (UInt32)hotkeyid;}public void UnregisterHotkeys(){Application.RemoveMessageFilter(this);foreach (UInt32 key in keyIDs.Values){NativeMethods.UnregisterHotKey(hWnd, key);NativeMethods.GlobalDeleteAtom(key);}}public bool PreFilterMessage(ref Message m){if (m.Msg == 0x312){if (OnHotkey != null){foreach (UInt32 key in keyIDs.Values){if ((UInt32)m.WParam == key){OnHotkey((int)m.WParam);return true;}}}}return false;}}
}

应用式方：

HotkeyHelper HotkeyHelper { set; get; }UInt32 CONTROR_F;UInt32 CONTROR_G;UInt32 F10;HotkeyHelper = new HotkeyHelper(this.Handle);CONTROR_F = HotkeyHelper.RegisterHotkey(Keys.F, HotkeyHelper.KeyFlags.MOD_CONTROL | HotkeyHelper.KeyFlags.MOD_SHIFT);CONTROR_G = HotkeyHelper.RegisterHotkey(Keys.G, HotkeyHelper.KeyFlags.MOD_CONTROL);F10 = HotkeyHelper.RegisterHotkey(Keys.F10, 0);HotkeyHelper.OnHotkey += new HotkeyEventHandler(OnHotkey);private void OnHotkey(int hotkeyID){if (hotkeyID == CONTROR_F){//do somethingMessageBox.Show("CONTROR_SHIT_F");}else if (hotkeyID == F10){//do something elseMessageBox.Show("F10");}}

局部热键(盘键快捷键的捕获)

/// <summary>/// 户用盘键快捷键取获与处置/// </summary>/// <param name="msg"></param>/// <param name="keyData"></param>/// <returns></returns>protected override bool ProcessCmdKey(ref Message msg, Keys keyData){KeyEventArgs e = new KeyEventArgs(keyData);if (keyData == (Keys.Alt | Keys.P)){//do something

}if (keyData == (Keys.Alt | Keys.Z)){//do something

}if (keyData == (Keys.F1)){//do something

}if (keyData == (Keys.F3)){//do something

}return true;}

文章结束给大家分享下程序员的一些笑话语录： 问：你觉得让你女朋友（或者任何一个女的）从你和李彦宏之间选一个，你觉得她会选谁？　　
　　答：因为李艳红这种败类，所以我没女友！
