最近研究一个键盘钩子 有些问题想咨询下！

[澄仙]

最近研究一个键盘钩子，用于设计一个快捷按键后触发一些事件

要在按完快捷键之后执行一个显示倒计时的程序，显示在一个文本框或者label里

请问我应该写在哪里，大致代码如下：

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

using System.Diagnostics;

        public const int WH_KEYBOARD_LL = 13;
        //LowLevel键盘截获，如果是WH_KEYBOARD＝2，并不能对系统键盘截取，Acrobat Reader会在你截取之前获得键盘。   
        HookProc KeyBoardHookProcedure;

写在public static int KeyBoardHookProc(int nCode, int wParam, IntPtr lParam)
里面。

请问怎么写才能让文本框内的倒计时的显示程序显示出来呢？
timer1是私有的
KeyBoardHookProc这个方法是静态的啊？我这块是菜鸟不懂 希望能给与详细解释 谢谢

[__天涯寻梦]

public static int KeyBoardHookProc(int nCode, int wParam, IntPtr lParam)
去掉 static 就是了

谢谢 好用了 对于静态方法还是不是太懂 呵呵 见笑了 马上给分结贴
