说明：  用Visual C++开发的电子邮件接收系统，用于学习用VC开发邮件软件。(Using Visual C++ Developed to receive e-mail system for studying the development of e-mail software with VC.)

邮件软件：该程序需要两个服务器，一个用来发送邮件，一个用来接受邮件，一般我们用pop3协议来接收邮件，用smtp协议来发送邮件。(E-mail software: the program requires two servers, one used to send a message, a message to accept the general protocol we use to receive mail pop3, smtp protocol used to send messages.)

站长写的一个使用FTP自动更新应用系统文件的程序，可以自动拨号( Stationmaster writes uses FTP automatically to renew the application system document the procedure, may the automatic digit dialing )

用vb结合bat和ftp实现远程键盘侦听(use VB code and Bat file,ftp to get the remote computer keyboard)

用C语言编写，分别攻击了Warftp和ccproxy两个漏洞（这两个漏洞只在windows xp sp2中存在，sp3和win7已经修复。因此需要安装一个sp2的虚拟机），攻击完成后，会弹出一个攻击成功的对话框，程序比较基础，但是能够帮助初学者深刻了解缓冲区溢出的原理。(Using C language, were attacked Warftp and ccproxy two vulnerabilities (both vulnerability only exists in windows xp sp2, sp3 and win7 has been repaired, so you need to install a virtual machine sp2), and after the attack is completed, it will pop up a successful attack dialog program basis for comparison, but a deep understanding of the principles that can help beginners buffer overflow.)

FTP上传下载源代码，用于上传和下，使用API函数写的，(FTP UP DOWN API)

自动发邮件的VC源码。想要的朋友可以下载

不错 (Yes!)

详细模拟了pop3协议的原理和实现，对pop3进行了较深入的分析(Detailed simulation of the pop3 protocol and the realization of the principle of pop3 conducted more in-depth analysis)

FTP端口的代码，也是书上的例题，虽然很小，但是很基础，帮助你们理解(FTP port code, is also a book example, although very small, it is the basis to help you understand)
