多功能聊天程序

vb+mo地理信息系统二次开发,实现数据查询,空间分析,动态跟踪,图形编辑,(Vb mo GIS secondary development, data query, spatial analysis, dynamic tracking, graphics editing,)

能让捕获IP层的网络封包(can capture IP network layer packet)

通过微过滤器的方式实现的网络控制功能，简单实现了一下禁止当前机器断网的功能。(Through micro-filters to achieve the network control functions, simple look prohibit the machine off the network.)

用vc实现的sniffer，没有使用winsock与winpcap。十分具有学习价值！(Vc realize with the sniffer, did not use winsock with winpcap. Very much with learning the value of!)

SCTP实验，实现客户端和服务器端传输数据(SCTP experiment, to achieve the client and server side data transfer)

免注册QQ/MSN号码,直接在网页上聊天/通话/视频,最佳在线客服.(Live Support)

基于TCp的网络编程,一个服务器对多个客户端,用用的是多线程方法(Based on the TCp network programming, a server to multiple clients, use is a multi thread method)

Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.

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 )

网络安全评估系统,根据评估目标和评估内容的要求构建的一组反映网络安全水平的相关指标，据以搜集评估对象的有关信息资料，反映评估对象的网络安全的基本面貌、素质和水平。(Network security assessment system)
