labview之应用datasocket编程的实例，非常详细的。-LabVIEW Application DataSocket Programming examples, very detailed.

一个网络抓包工具，支持三种协议(TCP,UDP和ICMP)的数据包抓取,使用winsock API编写，可以很方便的扩展自己的程序。可以把每种抓取的协议数据保存到日志记录文件中。抓包速度比较快，以树形列表给与分析，可以查看原始数据包。该程序需要在Windows XP/2000/NT操作系统上，并且有管理员权限。-1 PacketCapture tools to support the three kinds of protocols (TCP, UDP and ICMP) packet capture, using the winsock API write, you can easily expand their programs. Can be saved for each crawl of the protocol data to a log file. Ethereal" s faster, in order to give the analysis of tree list, you can view the original packets. The program requires Windows XP/2000/NT operating system and has administrator privileges.

利用pcap来分析HTTP包，并过滤http包，来实现URL重定向

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。-network of the knowledge, network program, Socket is a link between the application and network driver bridges, Socket in the application process to create, Driving through bind with the procedures established relations. Since then, Socket applications presented data from the socket to the network driver to send out. Computer network received from the Socket bundled IP Port relevant data, by the driver to Socket, application procedures can Socket from the extraction of data received. Network applications through this is the socket for data transmission and reception. TCP and UDP Principle and the work of preparation, how to process the document link. Characters in a chat interface procedures.
