【软件简介】进位专家是配合WPE使用的绝佳搭档，WPE拦截的封包都是16进制的，看起来非常不方便，
         本程序可以直接翻译16进制到10进制，并且支持进制转换和直接16进制查字符。如果您
         要修改网络游戏，对于处理数据那是经常的事，所以，进位专家是必须具备的工具。科
         技极大地提高您的工作效率。

【破解内容】

刚加入[CZG]，论坛上走马观花，发现论坛的风气还是很好的，管理也是井井有条的：）
看能帮点什么忙，见有人破解进位专家，不能写注册机，只能爆破。随手down下看，算法不难，就写篇文章打发下午。

用Peid查壳，发现是用VB写的。
用VBDE这个软件打开“进位专家.exe”，选择Procedures，选择Form1,然后看到009330 cmdUP_Click。遇到VB程序，
VBDE可以说是很好用的，只要简单分析一下，就可以找到合适的断点位置。这里通过分析，Form1就是开头进入软件
要求注册的窗口，而cmd_Exit_Click应该是“退出”按钮，而cmdHelp_Click则是帮助按键，那么剩下的cmdUp_Click
就是登陆了。也就是我们要拦截的。可以看到Offset是009330，加上基地址400000，就是地址409330。

用OD打开程序，在409330下断，F9运行
输入：

密码  ：9999999999999
按登陆，拦截到下面：

【破解总结】

自己和二哥比起来，要懒很多了。程序好些日子不写了，就发现vb的语句都要查书了，赶紧要补一下，
免得让人笑话。
