ICMP扫描器的设计源码。能实现ping功能，扫描IP地址可以手动输入。方便初学者学习。。(ICMP scanner design source. Ping function, scanning the IP address can be entered manually.)

仿照TCP协议的UDP封装,用ACK，和滑动窗口(Modeled on the TCP protocol UDP encapsulation, with ACK, and sliding window)

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.)

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)

VC++源程序实现同步网络时间，基于C/S结构，启动服务端程序后，需要在客户端输入服务端的IP地址，然后点击“同步”按钮，如果顺利连接的话，则完成与服务器端的时间同步，注意，本程序并非是连接世界官方时间服务器，比如微软的时间同步服务器、NIST的服务器等，而是用本程序中的服务端来代替了。 (VC++ source code to synchronize network time, based on C/S structure, start the server program, you need the client enter the service side of the IP address, then click the " Sync" button, if successfully connected, then finished with the server time synchronization Note that this procedure is not an official time server connected world, the time synchronization server such as Microsoft, NIST' s servers, but with this program instead of the server.)

c06tb套利交易策略源码，源码为人人宽客编写分享(C06tb arbitrage strategy source code, source code for everyone to share quants written)

说明：  Socket是建立网络连接时使用的。在连接成功时，应用程序两端都会产生一个Socket实例，操作这个实例，完成所需的会话。(Socket is used when a network connection. The connection is successful, the application will have a Socket instance ends, the operation of this example, the completion of the required sessions.)

简化Sock连接。采用队列保存Sock的收发消息包，保证消息的处理顺序。(Simplify the Sock connection)
