这是一个Tcp协议的网络引擎，包括两个部分： a、服务器采用完成端口模型，提供了丰富的接口函数 b、客户端采用三线程加重叠Io模型，速度快，稳定 都采用回调函数接收数据，是对网络Tcp模型Socket的完整封装，所有代码在Windows2000下测试通过，并已应用到很多现有的中型网络系统中。-This a remarkably agreement Network engines, including two parts : a server used to complete port model, a rich interface function b, client using three overlapping threads increases Io model, speed and stability using a callback function to receive information, the network model DEC Socket complete package, all of the code in the test under Windows 2000, and has been applied to many existing medium-sized network systems.

MFC开发的聊天室，有server和client 支持多人聊天 适合MFC开发者学习和使用- a chat room developed in mfc support multi_person chating

在给出的SMTP pop程序中加上一个过滤器，使能够对接收邮件的主题内容进行关键字过滤。关键字从文件中读出，不少于十个，比较结果符合的打印出过滤用关键字、邮件主题、邮件发件人。多重符合的每次结果都要打印。在windows Visual C＋＋ 下调试-SMTP pop in the given procedure to add a filter to enable the theme for the receiving e-mail content filtering keywords. Keywords from the document read out, of not less than 10, in line with the results of the comparison with the print keyword filtering, mail the theme of the message sender. Multi-line with the results of each must be printed. In windows Visual C++ under the debugger

该邮件服务器提供SMTP,POP3和Finger服务，多域名支持，帐户别名，多域别名支持，SMTP用户发信认证，RBL/RSS/ORBS/DUL和基于IP地址与邮件地址的垃圾邮件过滤功能-the mail server SMTP, POP3 and Finger services, domain name, alias accounts, multi-domain alias support, SMTP user authentication letter, RBL/RSS/ORBS/DUL and based on the IP address and e-mail address of the spam filtering

在线更新工具，支持断点续传功能，用VB遍的-Online Update tool to support the HTTP functionality, time and again with VB

比较高级的实用的网络配置工具，不是用控制面板的“网络”工具就可以实现网卡的配置，在有些情况下非常有用！使用了dll,注册表。此程序完整，稍加改动即可实用。 网络签名：lovenets.timessoft.com-comparison of practical network configuration tool, not a control panel "network" tool can be achieved NIC configuration, in some cases very useful! Dll used, the registry. This integrity of the process, a little change can be practical. Network Signed : lovenets.timessoft.com

计算校验和 校验和算法描述：为保证网络上传输的数据的可靠性，在许多协议中都设置了校验和项，例如：IPv4、ICMPv4、IGMPV4、ICMPv6、UDP和TCP 等等。计算这些校验和的算法称为网际校验和算法，简单来说就是：把被校验的数据１６位进行累加，然后取反码，若数据字节长度为奇数，则数据尾部补一个字节的０以凑成偶数。 由于从输入文件读入的数据不能直接满足计算校验和的条件，所以首先对从文件读入缓冲区的数据进行预处理，即读入缓冲区时忽略空格。由于累加是按16位进行的，所以每次从缓冲区中读出4个字符，并将字符转换成对应的16进制数字，如此依次累加，直至数据全部读完。 还有一种情况，即如果数据长度为奇数个字节，则需要判断，并补0累加。程序中利用的是缓冲区长度计数器i和当前读取到计数器j判断数据长度是否为奇数。即如果数据长度为偶数，则读完数据时当前读取到计数器j的值应与缓冲区长度i相等，而如果数据长度为奇数，则读完数据时，当前读取到计数器j>缓冲区长度i，此时需将缓冲区中剩余的两个字符读出，并补0，转换成相应16进制数以后参与累加。 当累加结束后，将累加和的16位以上数据位移下再进行一次累加，并对最后累加和取反即得所求校验和。 -calculated checksum checksum algorithm Description : To ensure the network transmission of data reliability, in many of the agreements are set up and calibration, for example : IPv4, ICMPv4, IGMPV4, ICMPv6. UDP and TCP so on. Calculating checksum algorithm called the Internet checksum algorithm, the simple answer is : as has been the calibration data for 16 cumulative, and then take the anti-code, if the data byte length of the odd, data will make up the tai
