说明：  这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错，我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素，比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》，内容变化不大("using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change)

VC.NET创建一个最简单的MFC程序,此为源码文件，真的是挺简单的MFC程序，想学习VC.NET环境的MFC编程，就要从最简单的MFC程序源码开始，难道不是么？ (VC.NET create a simple MFC program, this is the source file, is really quite simple MFC program, want to learn VC.NET MFC programming environment, it is necessary from the most simple MFC program source code starts, does not it?)

集合类（Set），用运算符重载实现并（+），差（—），交（×）等操作，并重载= 和-= ，实现Set S1，S2；…s1 = s2 和 S1-=S2；集合S1中去掉S2中的元素的操作 (Collections (Set), using operator overloading to achieve and (+), difference (-), cross (×) and other operations, and overloading = and-= to achieve Set S1, S2 ... s1 = s2 and S1-= S2 set S1 S2 removed in the operation of the elements)

多协议文件传输c/s网络应用设计与实现,程序用 TCP/UDP 两个协议模拟多协议服务器。首先服务器端要将两种协议的套接字创建好，并且监听 TCP 端口的连接。必要时使用select函数来进行多连接处理和非阻塞处理。而客户端直接可以按照发送的地址和端口号来进行通讯。 首先要运行服务器端，服务器会监听 TCP 端口。然后运行客户端，根据事先设定好的 IP和端口，就可以进行连接传输数据了。 程序实现的关键步骤： 以TCP协议为例 服务器端： 1.创建套接字；2.绑定端口；3.进入无穷的循环；4.接收请求；5.处理请求；6.应答。 客户端： 1.找到服务器的IP地址和协议的端口号；2.创建套接字；3.确定连接需要任意的，没有使用的端口号允许TCP去选择一个；4.将套接字和服务器连接；5.使用应用层协议和服务器交互；6.关闭连接。 (Multi-protocol file transfer c/s network application design and implementation of programs simulate multi-protocol server with TCP/UDP both protocols. First socket server to create a good two protocols, TCP port and listens for connections. If necessary, use the function to handle multiple connections and non-blocking treatment. And the client can follow directly address and port number to communicate. First run on the server side, the server listens on TCP port. Then run the client, according to pre-configured IP and port, you can connect the data transmission. The key step program implementation: In TCP protocol as an example Service-Terminal: 1.
