大学自考4.x软件41千字)
这是一个好软件，对于我等英语差的人更是一个福音。可以的话，请向作者注册，作者提到，当中很多东西都是他亲手录入的，我们尊重他的劳动。如果经济不能承受的话，请跟我来。
所用工具：
1、UNVFP&EXE 1.6（Build 999）标准版；
2、UltraEdit 32
===========================================================
由于标准版的UNVFP&EXE不公开发布，没有的朋友请下载精简版代替。
精简版下载地址：
http://extend.hk.hi.cn/~aming/2001/software/beta160.zip
帮助文件在1.50中：

============================================================
目前在国内加密VFP程序用得最多的是老王的VFP&EXE，这个的家伙要价太高了。
这个英语软件也是用它来加密的，用的不止是一种，还用了 20/20 的SoftSentry 3.0 和VFPLOCK 2.X。让我们把它的壳一层层脱掉。
1、启动UNVFP&EXE1.6，把ZK.EXE（该英语软件主程序）拖放到列表中，稍侯....成功脱掉VFP&EXE 1.85加密的壳，生成文件 “zk(已脱壳).exe”。
2、如果您使用的是标准版，脱壳前选用了“优先使用插件”的话，此时已经脱掉了SoftSentry的壳。否则需要重建VFP文件的PE头。以下是用标准版的附件DUMP下来的PE头。
3、反编译已脱壳的文件，发现注册标志。
IF NOREG=1 OR NOREG=2 则没注册，有NAG窗口提示及功能限制。
IF NOREG=0 已注册
4、以上语句对应的FOX代码。。。。
54 F7 15 00 10 FC F8 01 01 FD FE - NOREG=1
54 F7 15 00 10 FC F8 01 02 FD FE - NOREG=2
改很容易改吧。
将有有以上语句的地方改为：54 F7 15 00 10 FC F8 01 00 FD FE - NOREG=0
5、用标准版的“快速比较”可以找出以下地方需要改动：
42D43: 02 00
42E59: 01 00
42FEB: 01 00
430EA: 02 00
43146: 01 00
采用换VFP的PE头的方法，对于使用 20/20 SoftSentry、Armadillo 加密的VFP程序都有效。
