【文章标题】: Word方正转换器分析（完全破解）
【文章作者】: JackyChou
【作者邮箱】: jiaqicx@163.com
【软件名称】: Word方正转换器
【下载地址】: 自己搜索下载
【加壳方式】: themida 1.0.0.5
【保护方式】: 加壳
【编写语言】: VB 6.0
【使用工具】: OD、PEID、LordPE、ImportREC
【操作平台】: XP Sp3正版
【作者声明】: 只是感兴趣，没有其他目的。失误之处敬请诸位大侠赐教!
--------------------------------------------------------------------------------
【详细过程】
这次分析的程序是一个word转Fbd文件的程序，软件是用themida加壳，可以用脱壳脚本脱，但是脚本跑完后有偷代码，
并且IAT需要修复的。也可以用脱壳机脱，但是脱壳后程序可以正常使用，但是OEP不是并不是真正的OEP，需要手动再处理
下，并把无用的区段删除，到达软件减肥的目的。详细过程略。
进入程序分析：软件未注册的情况下，只能转换1页，超过就会出错。
程序启动时，会进行网络检查，如果没有网络的情况下，那么【开始转换】就会变灰并显示【网络不通】。下面把程序
启动时的部分代码贴出来看下：

通过上面的修改后，程序会显示已注册，并且在没有网络的情况下仍然可以使用。
下面开始分析点开始转换时的页数显示，解决完这个问题，就没有其他任何限制了，基本上是个无需注册的完美版了。
因为WORD超过页数，那么程序会提示错误并退出，所以比较容易找地方，这里就直接把转换那里的关键点贴出来分析下了。

测试了下，转换没有问题，断开网络，仍然可以转换。程序跟不用注册一样。
提醒：如果你分析程序后，把程序修改过后保存为另一个文件名，转换程序虽然成功，但是程序自动关闭再次打开时，发现
这次又出现要注册，并且不能转换多页以及无网络不能使用时，这时不要以为是程序破解的不对。
原因：在程序目录下，有个文件名为"backrun.exe"的程序。程序在转换完毕后，退出本程序并调用backrun.exe，而
backrun.exe是打开Word方正转换器.exe程序的，所以你原版还在的话，当然是启用原版啦。你破解完后，把原文件删除，
再把破解文件修改成原名即可。（当然也可以采用补丁方式。）

【经验总结】
拿到程序分析，首先要耐心，慢慢分析应该都能搞定的，不过小弟实在太菜，算法分析能力还比较差，目前还是在学习中，
以后可能会多分析算法，这样可能进步更快，希望高手多多指点，谢谢！！！
