**************************************************************
一、运行程序，进行注册，输入错误的注册信息进行检测，有提示信息
"Series number error,please check it and try again."
**************************************************************
二、用PEiD对ApDocToPDF.exe查壳，为 ASPack 2.12 -> Alexey Solodovnikov
**************************************************************
三、带壳调试，运行OD，打开ApDocToPDF.exe，输入注册信息，F12暂停，alt+K

【破解总结】
--------------------------------------------------------------
【算法总结】
1、注册码长度必须为16位
2、注册码的第8个字符和第11个字符ASCII值之和必须等于9Bh
3、注册码的第8个字符和第11个字符ASCII值之差加上41h必须等于第4个字符ASCII值
--------------------------------------------------------------
【算法注册机】
VB代码
Private Sub Command1_Click()
C11 = Int(Rnd() * 10)
C8 = Chr(&H9B - Asc(C11))
C4 = Chr(Asc(C8) - Asc(C11) + &H41)
Text1.Text = Int(Rnd() * 10) & Int(Rnd() * 10) & Int(Rnd() * 10) & C4 & Int(Rnd() * 10) & Int(Rnd() * 10) & Int(Rnd() * 10) & C8 & Int(Rnd() * 10) & Int(Rnd() * 10) & C11 & Int(Rnd() * 10) & Int(Rnd() * 10) & Int(Rnd() * 10) & Int(Rnd() * 10) & Int (Rnd() * 10)
End Sub
--------------------------------------------------------------
【注册信息】
一组可用的注册码：288x599i26292519
