TCPaUDP

说明：  务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。(Client server based on select I/O model. Programming interfaces in order to prevent obstruction, there is a sub-thread for receiving socket and select which treatment. There is only one client thread function, but its utilization very high, can be used for remote directory exchange, request the file size, create a number of threads to download the file. File transfer are uploading and downloading, as well as peer-to-peer transmission, this project, the specific means to transfer files to download.)

说明：  ARP协议发现局域网内的活动主机，vc++语言编写，用有界面，美观实用(ARP protocol found in the activities of the LAN hosts, vc++ language, with a interface, beautiful and practical)

说明：  mongoose v6.15，多线程http——server，线程数可设。从GitHub下载C语言原代码，在vc6里面编译成c++工程(multi-threads http_server, based on source code from Github. The project is conducted in VC6, converted from c language. The threads num can be edited in code.)

封装帧和解析帧，并有CRC校验，完全是自己手写(Feng binding and parsing frame, and a CRC checksum)

局域网QQ密码嗅探器QQsniffer,不要用于非法哦(LAN QQ password sniffer QQsniffer, not used in the illicit Oh)

用vc实现的sniffer，没有使用winsock与winpcap。十分具有学习价值！(Vc realize with the sniffer, did not use winsock with winpcap. Very much with learning the value of!)

在局域网内抓取所需要的IP数据包，使用VC++6.0工程编写。(Grab the required IP packets in the LAN.)

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

这是一个关于MODEM的网络编程源代码，采用VC++编写。(This is a MODEM network programming source code, written using VC++.)

基于VC++的局域网聊天室，能够实现多人房间聊天。(LAN chat room based on VC++ can realize multi-room chat.)
