vc winio驱动级模拟按键 简记

对于普通的模拟按键，利用keybd_event等系统函数即可，但是如果要在游戏里面模拟按键，因为部分游戏屏蔽了上述系统api，所以只能使用驱动级按键模拟。

#include <windows.h>
#include <stdio.h>
#include "winio.h"



void KbcWait4IBE()
{
	DWORD dwRegVal=0;
	do
	{	
		GetPortVal(0x64,&dwRegVal,1);
	}
	while(dwRegVal & 0x2);
}

void KeyPress(DWORD KCode)
{
	KbcWait4IBE();//Wait for KBC input buffer empty
	SetPortVal(0x64,0xD2,1);//Send data back to the system command

	KbcWait4IBE();//Wait for KBC input buffer empty
	SetPortVal(0x60,MapVirtualKey(KCode,0),1);//Send the key down scancode

	Sleep(10);

	KbcWait4IBE();//Wait for KBC input buffer empty
	SetPortVal(0x64,0xD2,1);//Send data back to the system command

	KbcWait4IBE();//Wait for KBC input buffer empty
	SetPortVal(0x60,(MapVirtualKey(KCode,0) | 0x80),1);//Send the key up scancode
}


void main()
{

  bool bResult;


  // Call InitializeWinIo to initialize the WinIo library.

  bResult = InitializeWinIo();

  if (bResult)
  {
	Sleep(5000);
	printf("supposed key down");
	KeyPress(73);
	Sleep(5000);
    // When you're done using WinIo, call ShutdownWinIo
    ShutdownWinIo();

  }
  else
  {
    printf("Error during initialization of WinIo.\n");
    exit(1);
  }
}

调用KeyPress(73);会模拟按键i。这一小段代码的精妙之处就在于可以绕过绝大部分游戏的检测机制，可谓是外挂利器
