socket

vb局域网对讲机，实现两台机器之间的通信(vb LAN radio to achieve communication between two machines)

VC UDP通讯，后台服务器 FileMana.cpp FileMana.h Login.cpp Login.h resource.h SocketUdp.cpp SocketUdp.h StdAfx.cpp StdAfx.h WinSockUDP.aps WinSockUDP.clw WinSockUDP.cpp WinSockUDP.dsp WinSockUDP.dsw WinSockUDP.h WinSockUDP.ncb WinSockUDP.opt WinSockUDP.plg WinSockUDP.rc WinSockUDP.sln WinSockUDP.vcproj WinSockUDP.vcproj.T400-CKX.Administrator.user WinSockUDPDlg.cpp WinSockUDPDlg.h( FileMana.cpp FileMana.h Login.cpp Login.h resource.h SocketUdp.cpp SocketUdp.h StdAfx.cpp StdAfx.h WinSockUDP.aps WinSockUDP.clw WinSockUDP.cpp WinSockUDP.dsp WinSockUDP.dsw WinSockUDP.h WinSockUDP.ncb WinSockUDP.opt WinSockUDP.plg WinSockUDP.rc WinSockUDP.sln WinSockUDP.vcproj WinSockUDP.vcproj.T400-CKX.Administrator.user WinSockUDPDlg.cpp WinSockUDPDlg.h)

服务器，客户端聊天小程序，可能功能有点简单，但是原理都在(The server, the client chat applet)

Visual C++ .NET 网络与通信高级编程范例配套代码(Visual C++. NET network and high-level programming paradigm supporting code)

检测NAT类型的客户端，程序中指定了服务器IP地址，用户可以自行修改(Detect NAT type of the client, the program specifies the server IP address, the user can modify)

用MFC 开发的基于UDP协议的网络科学计算中心,比较适用于局域网内(Using MFC development agreement based on the UDP network Scientific Computing Center, more applicable to the LAN)

modbus 测试，用VB的winsock控件实现的modbus tcpip通讯等(modbus test, with VB the winsock control to achieve the modbus tcpip communications)

通过客户端与服务器端文件对比，实现自动升级功能。(Through the client and server-side document comparison, automatic update feature.)

强大的C++邮件服务器系统...不可多得.(Strong C++ mail server system ... rare.)

说明：  代理服务器，还不完善，总丢数据，个人没有能力改了，有需要的朋友参考一下吧(Proxy server, not perfect, the total lost data, individuals can not afford to change, and a friend in need reference it)
