外挂和自动操作电脑的案例

#include <Windows.h>

int main() 
{
    MessageBoxA(0, "您是微软第一亿用户，恭喜你，微软会给你100万美金", "恭喜"， MB_OK);
}

 为了做得更好，调整代码，让用户无法查找文件来源，使用注入软件把 dll 文件注入，隐藏运行文件

#include <Windows.h>

__declspec(dllexport)
int go() 
{
    MessageBoxA(0, "您是微软第一亿用户，恭喜你，微软会给你100万美金\n请拨打带电话xxxx获奖", "恭喜", MB_OK); 
    return 0; 
}

玩游戏作弊，使用修改游戏软件修改植物大战僵尸的数据

查找出地址，把 dll 文件注入软件

__declspec(dllexport)
void go()
{
    int *p = (int *)0x1D0D1530;
    *p = 500;
}

调整一下代码，让数据不会减少

__declspec(dllexport)
void go()
{
    int *p = (int *)0x1CE0DF40;
    while (1)
    {
        if (*p <= 500)
            *p = 500;
        Sleep(1000);   
    }
}
