键盘钩子 C++ HOOK 超级好用
使用方法
1、定义头文件
#ifdef DLLEXPORT
#define BAPI extern"C" __declspec(dllexport)
#else
#define BAPI extern"C" __declspec(dllimport)
#endif
BAPI void HelloZB();
2、添加库文件（使用DLL生成的LIB文件）
3、调用函数
HelloZB();
DLL C++代码
#include <windows.h>
#include <stdio.h>
HINSTANCE hins = NULL;
HHOOK MaiNHook = NULL;
BYTE kso[1024];
BOOL APIENTRY DllMain( HMODULE hModule,

break;

case DLL_PROCESS_DETACH:
break;
}
return TRUE;

#ifdef DLLEXPORT
#define BAPI extern"C" __declspec(dllexport)
#else
