C# 实现QQ 登陆、登出，获取好友以及群列表 然后群发消息 基于QQ2011 PC版协议【附完整源码】

说明：  OpenGL ES2,0开发库和OpenGL ES3,0开发库有差别,保留对OpenGL ES2,0开发库的使用 用RAR5,4解压(The OpenGL ES2,0 development library is different from the OpenGL ES3,0 development library, and the use of the OpenGL ES2,0 development library remains unzipped with RAR5,4)

tcp查看器，可以查看tcp协议的相关信息，还包括设置，等等，对学习tcp协议有很大帮助(tcp viewer, can view information about tcp protocol, but also include the provision, and so on, to learn tcp protocol has very helpful)

说明：  Bot engine for Travian3 online game

利用http协议实现网络通信,是基于c语言编写(Use the HTTP protocol to realize network communication, is based on the c language)

计算网络静态参数的直径c程序（其中的数据是具体的可换成其他的数据）。(computing network diameter of the static parameters c (which is specific data can be replaced by other data).)

说明：  数值方法中用c++编写的数值矩阵直接三角分解法求解线形方程组的算法,(In the numerical method, a numerical matrix direct triangular decomposition method written by c is used to solve the linear equations.)

端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)

说明：  这是一个极其简单的服务器源码。。。。仅供学习参考(This software is copyright 1999 by J. David Blackstone.)

ping工具，基于控制台应用程序，类似cmd的ping功能(ping tools, console-based application)
