[软件名]名家庭银行家 2.0 alpha build 43
[软件介绍]这是一个家庭理财软件的项目。我们以前用过的名称是："欢乐家庭-理财软件"和 "M99 家庭理财软件"，现在将它改名为"家庭银行家"，希望它能够帮你管好帐、理好财。
[破解过程]首先查看无壳,delphi编写,赚了一步,哈哈.先用dede得map文件后OD导入,输入注册,提示"失败",查字符串,分析得知是由注册名经运算后得到注册码,再与假码比较,相同则注册成功,反之失败.过程如下：哇噻，12：30了，伸了懒腰才！
本人学习破解有二月有余了，看了后自己也搞了一些自己常用的软件，前二天在上面看了一位朋友破的delphi软件，正好我有一个，也就拿来试了试，真苦，花了二天的时间来仔细研读，终于搞清了整个算法过程了

小结:
1.由注册名从后信前依次取出每个字符得出一个16进制数,后变成10进制a(i),注册名的个数大于7时，只取后7位，把每次得到的10进数连起来，计为串A，即：a(1)a(2).......a(i), i小于等于7
2.把串A换成16进制，计为B
3. 看串B中有无不是数字或字母的字符，有则除去，除去后若B不够12位，则在字符串前加0至12，得出正确的注册码.
如：注册名：lsezxsy 组织：任意（不参与计算） 得出
A：52781082497812 B：20010DAC5314
VB注册机正在写,往后,如有人需要,我再放上去.
