我是靠谱客的博主幸福黑夜，最近开发中收集的这篇文章主要介绍CreateRemoteThread简单应用，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

char szMsg[12]; //MessageBox函数中显示的字符提示

typedef int (__stdcall * PFN_MESSAGEBOX)(HWND, LPCTSTR, LPCTSTR, DWORD);

//线程函数定义

{
//只要使用api必须拦截 !!!!!!!!

pfnMessageBox = (PFN_MESSAGEBOX)pRP->dwMessageBox;
//就是这句有错！！！！！！！！！
pfnMessageBox(NULL, pRP->szMsg, pRP->szMsg, 0);
return 0;
}
