c语言安装全局消息钩子的源代码 

 1 #include <stdio.h>
 2 #include <conio.h>
 3 #include <windows.h>
 4 #define DEF_DLL_NAME  "keyHook.dll"
 5 #define DEF_FUN_NAME  "keyboardPrc@12"
 6 
 7 
 8 
 9 int APIENTRY WinMain(HINSTANCE hInstance,
10                      HINSTANCE hPrevInstance,
11                      LPSTR     lpCmdLine,
12                      int       nCmdShow)
13 {
14     int hwndDOS = GetForegroundWindow();
15     ShowWindow(hwndDOS, SW_HIDE);
16     HMODULE holl=NULL;
17     HOOKPROC process = NULL;
18 
19     holl = LoadLibraryA(DEF_DLL_NAME);
20     if(holl==NULL){
21         printf("导入库失败");
22     }
23     process = (HOOKPROC)GetProcAddress(holl,DEF_FUN_NAME);
24     if(process==NULL){
25         printf("导入函数失败");
26     }
27     SetWindowsHookEx(WH_KEYBOARD,process,holl,0);
28     _getch();
29 
30     return 0;
31 }

上面是主函数的代码，下面是keyHook.dll的代码

注意dll与主文件一定要放在同一个文件夹里，效果是键盘会失灵，打开任务管理器把进程关掉就行

#include <stdio.h>
#include <windows.h>
__declspec(dllexport) LRESULT CALLBACK keyboardPrc(int code,WPARAM wParam,LPARAM lParam){
    return (long)1;
}


窗口是隐藏的，会有一闪而过。
