写外挂都用的是网上的帖子HOOK目标程序的send和recv，然后采用WriteProcessMemory替换我们的函数和Windows API函数，不断的来回切换，这个其实数据密集的时候容易出错也不稳定，不提倡！并且代码输写很容易出错。这里我贴出我自己写过的HOOK库，用过攻城略地和大皇帝等等游戏，均通过测试，非常之稳定。
把MHOOK封装成动态链接库，直接调用DLL文件进行HOOK目标函数，也可以实现远程注入。并且不会被游戏反外挂发觉。动态链接库代码如下：

IT十万为什么
在你网站发个帖子说明是认证的这个帖子的，贴到这个帖子里。 最近公司项目搞的天天加班，不好意思。
今天在我网站发布了一篇文章，地址:http://www.ithtw.com/7625.html
再上一张图，算是有图有真相！

发博客的那个链接，网站的时间太靠后，是转载的吧。 晕，算了!
我还是回看雪好了。
