实现FTP多线程下载上传，同时可以方便实现与本机FTP服务器的连接(Achieve multi-threaded FTP download upload, and can easily be achieved with the local FTP server)

当遇到网上下载的很多歌txt文件电子书，或程序生成的多个txt，可根据文件名合并成一个，自己写的，大方分享(Txt file, e-book experience online download many songs, or program generated txt, based on the file name to be merged into one, write your own, and generous sharing)

TCP和UDP socket编程，向固定服务器发送学号姓名信息，用udp从服务器获得一个随机字符串(TCP and UDP socket programming, Student ID Name information sent to the fixed server udp from server to obtain a random string)

应用于windows 平台下的vc编程，主要是windows socket 下的网络编程(windows socket programming, including basic knowledge of the single-threaded, multi-threaded. Development and application in the windows platform)

程序可以获取本机IP地址，需要先加载Socket库(Program can access the machine IP address, need to load the Socket Library)

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.)

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.
