C++编写Windows全局键盘钩子记录键盘输入

1.键盘钩子处理程序 HookProc

2.键盘钩子安装程序 InstallHook

3.键盘钩子卸载程序 UnInstallHook

4.键盘钩子dll的加载，安装与释放

生成标准windows dll提供给其它工程用于键盘钩子安装与释放

 声明：

#ifdef KEYBOARDHOOK_EXPORTS
#define KEYBOARDHOOK_API __declspec(dllexport)
#else
#define KEYBOARDHOOK_API __declspec(dllimport)
#endif

HHOOK _hook;//用于保存安装与卸载Hook用的句柄
HINSTANCE _hinst;//Hook实例的句柄
LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam);//Hook处理
KEYBOARDHOOK_API bool InstallHook(void);//安装Hook
KEYBOARDHOOK_API bool UnInstallHook(void);//卸载Hook

实现： 

#include "stdafx.h"
#include "KeyboardHook.h"

//处理键盘消
