有很多完整的范例，不过范例太完整反而不好，许多语句不知是啥用处

我自己写了个sock类，因为WINSOCK不支持引用（做成安装盘有问题，并且不支持多线程）
超OUTLOOK软件，提供源代码
楼主： 本软件是我在业余时间完成,我的目标是将它做成国内一流的客户端邮件软件.现在初具模型
.正在修改中.它有一下特点:
1. 基于SDK模式开发
2. 大量源代码:软件中用到的所有组件,包括每一个按钮,均是自己所写.形成了自己风
格的完整的一套组件库.他们包括:列表,文件管理,菜单等
所有代码均参照标准协议写成
3. 由以下功能模块组成:邮件;新闻组;FTP;任务及其在之基础上的相应管理.如文件管
理等.
4. 合作方式:转让经营权;根据你们需要提供技术支持;作为贵公司产品发布等,我们可
以详细谈.我的联系方式是:myganlimei@163.com 13062323245
一下为该软件部分运行界面图:
安装盘下：ftp://uploads@2ccc.com/SmartMai_Setup.EXE
代码下：ftp://uploads@2ccc.com/SmartMail_Code.rar
ftp密码：uploads
建议大家先下安装盘，因为比较新，
