网络重传选择协议，可以检查传输信息的正确性。通过接受方的校检，通知发送方重新发送。 ( Network retransmission protocol, you can check the correctness of the transmission of information. By accepting the prosecution s school to notify the sender to resend.)

这是VB6.0上MSDN的例子，不过我做了稍微改动，能实现输入任意的IP地址，实现与其通信的目的(This is a VB6.0 example on MSDN, but I make a slight alteration can realize arbitrary input IP address, the realization of the purpose of communication)

说明：  这是一个比较复杂的远程控制工具,分为服务器与客户斋,让你了解socket编程的知识.(This is a more complex remote control tools, is divided into server and client fasting, so that you understand socket programming knowledge.)

我的毕业设计 已通过答辩 计算机网络安全中防火墙技术和端口扫描技术 网络扫描器设计(My graduation project has passed the defense computer network security, firewall technology, and port-scanning technology network scanner designed)

用Winsocket实现网络中聊天和文件传输, VC++编写(you can use it to communicate with other or transfer some files.)

守候远程控制VC++源码，任意开源。已在XP下编译通过并运行。(Waiting for remote control of VC++ source code, any open-source. Has been compiled by and run under XP.)

这个是EV1527的标准解码程序，电动型，四建功能独立。

socket编程实现服务端与客户端互发消息(exchange message between server and client)

这是一个用c++编写的，socket API 的服务器端和客户端的相互响应的简单程序.用cmd打开程序exe，输入“webserver + 端口号”，webclient方面，输入“webclient + 127.0.0.1 + 端口号5600”，则可以在客户端上显示接收到的信息。(This is a c++ written in response to a simple procedure of mutual socket API server and client' s Open Program exe, enter " webserver+ port number" , webclient, the input " webclient+ 127.0.0.1+ port number 5600 with cmd " you can display the information received on the client.)

基于udp实现可靠传输的原理实现了一个简易的邮件系统。存储利用文件来实现，不涉及数据库。(Udp achieve reliable transmission based on the principle of achieving a simple mail system. Storage of papers to achieve, does not involve a database.)
