全局钩子，HOOK编程，
建立DLL项目：
代码如下：
#include"pch.h" #define _DLL_API #include"MyDLL.h" HHOOK MouseHook = NULL; HHOOK KeyBoargHook = NULL; HINSTANCE g_hinst; //获取主模块的句柄， //创建一个节，只要是包含在节内的数据，多进程是共享的，节内的数据必须初始化，dumpbin /headers 查看dll信息 #pragma data_seg("MySec") HWND g_hwnd = NULL; #pragma data_seg() #pragma comment(linker,"/section:MySec,RWS") //使用linker连接方式，设置MySec读写共享权限 //鼠标钩子 LRESULT __stdcall MouseProc(int nCode, WPARAM wparam, LPARAM lparam) { return 1; } //键盘钩子 LRESULT __stdcall KeyBoardHook(int nCode, WPARAM wparam, LPARAM lparam) { if (wparam == VK_F2) //当按下F2时退出 { ::SendMessage(g_hwnd, WM_CLOSE, 0, 0); UnhookWindowsHookEx(KeyBoargHook); } return 1; } //接口 void SetMouseHook(HWND hwnd) { g_hwnd = hwnd; MouseHook = SetWindowsHookExW(WH_MOUSE, MouseProc, g_hinst, 0); } //接口 void SetKeyBoardHook(HWND hwnd) //为了给主窗口发消息，我们定义了一个窗口句柄参数。 { g_hwnd = hwnd; KeyBoargHook = SetWindowsHookEx(WH_KEYBOARD, KeyBoardHook, g_hinst, 0); }
