使用WH_KEYBOARD_LL，不要使用WH_KEYBOARD，则可以把全局键盘钩子过程放在exe中，不需要dll。

例代码 ：

VC6

新建Win32 Application工程，选A simple Win32 application，修改代码如下：

===================================================

#include "stdafx.h"

#define ULONG_PTR ULONG

#define WH_KEYBOARD_LL 13 

typedef struct {  

  DWORD     vkCode;  

  DWORD     scanCode;  

  DWORD     flags;  

  DWORD     time;  

  ULONG_PTR dwExtraInfo;  

} KBDLLHOOKSTRUCT, *PKBDLLHOOKSTRUCT; 

HHOOK keyboardHook = 0;

LRESULT CALLBACK HookCallback(int code, WPARAM wParam, LPARAM lParam);

// Foward declarations of functions included in this code module:

int APIENTRY WinMain(HINSTANCE hInstance,

                     HINSTANCE hPrevInstance,

                     LPSTR     lpCmdLine,

                     int       nCmdShow)

{

MSG msg;

MessageBox(0,"挂载全局键盘钩子","aa",0);

    keyboardHook = SetWindowsHookExA(WH_KEYBOARD_LL, HookCallback, GetModuleHandleA(0), 0);

    if (keyboardHook == 0)

    {

        MessageBox(0,"挂载全局键盘钩子失败","aa",0);

        return -1;

    }

while (GetMessage (&msg, NULL, 0, 0)) //试着用while(TRUE)而不用消息循环不起作用

{

TranslateMessage (&msg);

DispatchMessage (&msg);

}

MessageBox(0,"程序正常退出，卸载全局键盘钩子","aa",0);

UnhookWindowsHookEx(keyboardHook);

return msg.wParam;

}

LRESULT CALLBACK HookCallback(int code, WPARAM wParam, LPARAM lParam)

{

KBDLLHOOKSTRUCT *ks = (KBDLLHOOKSTRUCT*)lParam;

if(ks->vkCode == 'Q'  && wParam==WM_KEYDOWN) //按下Q键

{

PostQuitMessage(0);

return 1;

}

return CallNextHookEx(0, code, wParam, lParam); //CallNextHookEx 的第一个参数忽略?

// return CallNextHookEx(keyboardHook, code, wParam, lParam);

}

//如果要检测 a-z 键，要使用大写 A-Z 不然会无效并且检测到其他按键，小写的 a-z 与其他VK_键重叠(baidu)
