PacketCapture

说明：  监控本地网卡网络流量, 如果有多个网卡, 可分别统计每个网卡的进出网络流量, 并统计总的网络流量.(Monitoring the local LAN network traffic, if there are multiple network cards, network cards can access statistics for each network traffic and overall network traffic statistics.)

说明：  根据域名获得IP地址列表 根据域名获得IP地址列表(under the name list of IP addresses under the domain of IP address list)

说明：  MFC实现多线程 简单端口扫描程序 能自定义线程数量及扫描端口范围(MFC simple multi threaded port scanner can scan a custom port number and scope of the thread)

该程序模拟知乎，作为网上问答系统，用户能注册，登录，提问，回答，点赞，关注，取关，查找问题，等一系列操作,一个服务器端可以同时连接多个客户端，能够同步各个客户端操作结果。程序分为客户端和服务器端，用户gui采用mfc编写，通信方式为socket方式，开发环境为win7 vs2015，编译器v140.(The program simulates know almost as online quiz system, users can register, login, questions, answers, thumbs up, focus on, take off, find the problem, and a series of operations, a server can be connected to multiple clients simultaneously, it is possible to synchronize each client operating results. Program is divided into client and server side, the user using mfc gui written communication for the socket, the development environment for win7 vs2015, compiler v140.)

VC++实现类似于QQ文件传输功能的文件发送与接收程序示例，分为服务端和客户端，客户端首次接收数据，将判断文件包大小，数据包中一定包含完整的数据包结构信息，数据不一定完整；读取数据包的大小，包含数据包结构大小和数据大小，之前接收的数据与现在接收的数据能够构成至少一个完整的数据包，文件接收完毕则设置结束标记，若终止的连接，则弹出窗口告诉用户，对方终止了文件传送。 　　服务端程序是比较简单的，基本是复制文件数据、判断文件是否传递成功、等待对方收受发送任务或取消发送任务，分包继续发送文件等功能(VC++ implementation is similar to QQ file transfer capabilities to send and receive files program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, and previously received data received data can now constitute at least one complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer. Server program is relatively simple, basically copying the file data, to determine whether the file transfer is successful, waiting for the other to accept or cancel the sending task sends tasks, subcontractors continue to send files and other functions )

用Visual C++编写的UDP客户端程序。(Using Visual C++ Prepared UDP client program.)

说明：  一款与CuteFTP软件相媲美的源代码,非常值得下载，学习和参考Ftp工具VC++编程必不可少的源码，学习和使用FTP的朋友不仿下载一看!(A match with the CuteFTP software source code, very worth the download, Ftp tools for learning and reference VC++ Indispensable source programming, learning and use FTP to download the friend does not like a look!)

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。 (side is based on the Treasury select I/O model. To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)

基于UDP协议通信 实现电脑之间的字符通信 简单的聊天功能(character communication based on UDP )

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++.)
