C++模拟游戏中鼠标点击和键盘按键

游戏中模拟键盘输入，有时回被系统屏蔽，Java等语言都试过很多方法，好像都没用，所以下面给出一种C++实现方法

#include <iostream>
#include <windows.h>
// for key pushing
BYTE scan_code(DWORD pKey)
{
    const DWORD result = MapVirtualKey(pKey, MAPVK_VK_TO_VSC);
    return static_cast<BYTE>(result);
}
void press_key(DWORD pKey)
{
    keybd_event(static_cast<BYTE>(pKey), scan_code(pKey), 0, 0);
}
void release_key(DWORD pKey)
{
    keybd_event(static_cast<BYTE>(pKey), scan_code(pKey), KEYEVENTF_KEYUP, 0);
}
// for testing
#define PRESS(x) press_key(x); std::cout << "Press: " #x << std::endl
#define RELEASE(x) release_key(x); std::cout << "Release: " #x << std::endl
// test
int main(void)
{
    Sleep(3000);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    Sleep(10);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
    int len = 10;
    int i=0;
    for (i=0;i<len;i++)
    {
        PRESS(65);
        Sleep(100);
    }
}
