本程序由爱页工作室(www.ayeah.net)使用C#在VS2008上开发
目前发布第一版v0.9
有以下功能：
1、输入QQ号码提取所有聊天记录为TXT文件（包括普通聊天记录、群聊天记录、临时会话。。。）
2、一键打包成rar（自动调用rar.exe）
3、发送到邮箱中做备份（使用SMTP）
其它说明：
本程序需要.net framework 2.0以上版本运行库
本程序为绿色版，不用安装，不写注册表，解压到任意目录即用，可自动识别QQ所在目录
聊天记录导出不需要密码，对于本地消息加密的MsgEX.DB暂未测试。
本程序只作聊天记录备份之用，请勿用于偷窥他人隐私。

参考了以下内容：
1、解密QQ消息文件格式

2、Decompiling CHM (help) files with C#

另外还有发邮件的代码就不发了，简单的调用cdosys.dll发的，还有调用rar.exe的也很简单，就几行代码，不贴了，自己反编译吧，我没混淆~~
不想直接发源码是讨厌很多人拿去改掉我的名字和网址就当自己的“原创”了。。。
