实现可靠的UDP封装传输类，可以进行多点传输，采用超时重发机制(Reliable transmission of UDP encapsulation type, can be multi-point transmission, the use of timeout retransmission mechanism)

说明：  arj欺骗代码,c语言,以可改变网卡接收模式,获取所有经过的数据包(arj cheat code, c language, in order to change the network card can receive mode, after obtaining all the data packets)

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)

这是VB6.0上MSDN的例子，不过我做了稍微改动，能实现输入任意的IP地址，实现与其通信的目的(This is a VB6.0 example on MSDN, but I make a slight alteration can realize arbitrary input IP address, the realization of the purpose of communication)

孙鑫VC++教学课程lesson14：网络的相关知识，网络程序的编写，Socket是连接应用程序与网络驱动程序的桥梁，Socket在应用程序中创建，通过bind与驱动程序建立关系。此后，应用程序送给Socket的数据，由Socket交给驱动程序向网络上发送出去。计算机从网络上收到与该Socket绑定的IP+Port相关的数据后，由驱动程序交给Socket，应用程序便可从该Socket中提取接收到的数据。网络应用程序就是这样通过socket进行数据的发送与接收的。TCP与UDP的工作原理与编写过程，如何在程序中链接库文件。一个字符界面的聊天程序。(Sun Xin VC++ tutorial lesson14: the knowledge of the network, network program, Socket is connected applications and network drivers bridges, Socket application to create, build relationships bind driver. Thereafter, the data of the application to give socket, by the Socket handed driver and sent out on the network. After binding with the Socket IP+Port related data is received by the computer from the network, by the driver to the socket, the application can extract the data received from the Socket. Network application is sending and receiving data through the socket. TCP and UDP works and the writing process, how to link library files in the program. A character interface chat program.)

可以参考直接使用S7协议连接西门子plc(You can refer to the direct use of the S7 protocol to connect SIEMENS PLC)

获取硬件信息 Get hardware information()

本例为魔兽世界客户端自动更新程序,采用URLDownloadToFile异步机制实现.(World of Warcraft in this case the client automatically update procedure for the asynchronous mechanism URLDownloadToFile achieved.)

VC++编写的聊天程序。可在局域网内进行聊天。界面清晰(VC++ to prepare the chat program. Can be carried out in the local area network chat. Clear interface)

获取本地计算机信息的小代码，比较简单，适合初学网络编程(a simple program of geting information from computer)
