socket

TCP端口扫描，可以获得指定IP段内的主机名，mac地址，存活端口，并将这些信息保存在SQLITE数据库，下次可以直接读取数据库信息，移值性好！(CP port scan, you can get within the segment specified IP host name, mac address, survival ports, and the information stored in the SQLITE database, the next can be read directly, transfer value is good!)

简单TCP双向通讯例子，实现客户端服务器端的双向通讯。(Simple the TCP bidirectional communication example, to achieve the client server-side two-way communication.)

一个抓包小工具，获取网络上面其它装置之间通讯报文(a tool that get a net reports between other equipments)

TCP和UDP socket编程，向固定服务器发送学号姓名信息，用udp从服务器获得一个随机字符串(TCP and UDP socket programming, Student ID Name information sent to the fixed server udp from server to obtain a random string)

利用socket技术，实现了局域网之间的通信，两个客户端之间可以相互聊天(Socket technology, communication between the LAN between the two clients can chat with each other. )

实现通用的程序升级功能，可以检查是否有更新，下载更新(Achieve universal upgrade feature, you can check for updates, download updates)

实现简单的聊天室设计 包括服务器和客户端的设计(Simple chat room design )

UDT网络传输协议开源包，是基于UDP的可靠传输协议，支持P2P，有现成的文件传输函数，速度比TCP快。(Open source packages of the UDT network transport protocol is UDP-based reliable transport protocol to support P2P, there is a ready-made file transfer function, the speed is faster than TCP.)

一个简单的TCP聊天程序，使用winsock api实现。(A simple TCP chat program)

说明：  本程序是window平台下，使用virtual C++编写文件下载程序，使用了Http协议(This program is a window platform, use the virtual C++ writing the file download process, using Http protocol)
