呵呵，我们开工吧！唉！^-^我的水平很低，许多地方表达的有问题，烦请各位指教！
用ollydbg加载运行 ,在注册框中填注册试验码:789456 (软件提示只要5~6位数字)后下
bpx GetDlgItemTextA 后按OK键后不久就能来到这里:

以上计算的总结：注册码取值范围
1.第一个比较循环时用第二次计算的字符串的ｈｅｘ值＊２作指针在以 0049A460 开始的内存中查表，得到的值 AND 8 ,比较得数如果是０就到第二个比较循环．
２．第二个比较循环用第二次计算的字符串的ｈｅｘ值＊２作指针在以 0049A460 开始的内存中查表，得到的值 AND 4 ,比较得数如果是０就OVER.即查表得到的值 AND 4 不能＝０
经过计算可以知道表中 0049A460 开始的十个值－'84 '符合条件，第一个８４的偏移量＝60ｈ那么第二次计算的字符串的ｈｅｘ值的范围是60／２＝30到3A即第二次计算的字符串的范围是0～9．
(以上是一个定式)
这样就能保证注册码是数字 .

====================================================
到这里注册码的算法跟踪完成,下面来分析注册码的计算方法.
(按照提示长度是5~6位数字)
经过分析可以知道,注册码分三种情况.每种有4个符合条件的注册码
1.去除21天限制版,价值$12.
计算方法:
1.)注册码的16进制值+3D0C09 = 40F0E1
可逆的计算是注册码=40F0E1-3D0C09=3E4D8(H)==> 255192
2.)注册码的16进制值+3D0C09 = 413169
可逆的计算是注册码=413169-3D0C09=4258D(H)==> 271757
3.)注册码的16进制值+3D0C09 = 40B079
可逆的计算是注册码=40B079-3D0C09=3A470(H)==> 238704
4.)注册码的16进制值+3D0C09 = 407031
可逆的计算是注册码=407031-3D0C09=36428(H)==> 222248
2.去除21天限制版,价值$15.
计算方法:
1.)注册码的16进制值+3D0A43 = 40F0E1
可逆的计算是注册码=40F0E1-3D0A43=3E69E(H)==> 255646
2.)注册码的16进制值+3D0C09 = 413169
可逆的计算是注册码=413169-3D0A43=42726(H)==> 272166
3.)注册码的16进制值+3D0C09 = 40B079
可逆的计算是注册码=40B079-3D0A43=3A636(H)==> 239158
4.)注册码的16进制值+3D0C09 = 407031
可逆的计算是注册码=407031-3D0A43=365EE(H)==> 222702
3.PRO版,价值$200.
计算方法:
1.)注册码的16进制值+3D09A7 = 40F0E1
可逆的计算是注册码=40F0E1-3D09A7=3E73A(H)==> 255802
2.)注册码的16进制值+3D0C09 = 413169
可逆的计算是注册码=413169-3D09A7=427C2(H)==> 272322
3.)注册码的16进制值+3D0C09 = 40B079
可逆的计算是注册码=40B079-3D09A7=3A6D2(H)==> 239314
4.)注册码的16进制值+3D0C09 = 407031
可逆的计算是注册码=407031-3D09A7=3668A(H)==> 222858
