PtoP-CHAT

基于TCP/IP的多人聊天程序(包含服务器和客户端)( Chat the procedure based on the TCP/IP multi- people (to contain server and customer end) )

利用socket实现简单文件传输,mfc实现，很简单(Simple file transfer using socket, mfc achieve)

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)

允许用户网络chat交流并且更新，共享文件 (Internet chat allows users to exchange and update, share files)

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.)

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.)

聊天程序的源码，对学习socket编程很有帮助。(Chat program source code, useful for learning socket programming.)

基于Winpcap的网络数据包抓取.开发环境VS2013(network packet capture based on Winpcap . Development environment: VS2013)

说明：  局域网视频会议，vc6.0/Windows XP编译通过。(LAN video conferencing, vc6.0/Windows XP compile.)
