UDP方式，实现client和server的通信。

一个简单的vc下tcp服务器端程序服务器端的程序当有客户提出连接请求时，在端口与客户端进行连接，连接成功后，显示客户IP地址和端口号，并给客户端发送“Hello!I am a server.”字符串。如果发送正确则显示所发送的字节数-Vc under a simple tcp server-side server-side program when connection requests made by the customer, in the port and connect the client to connect successfully, the display client IP address and port number, and to the client to send

vc++编写的用多线程实现客户-服务器结构的一个例子，有学习价值-vc prepared by using multiple threads to achieve client-server structure of an example, learn the value

线程安全实例。该程序说明线程安全问题。该例子实现的功能与多线程并发服务器实例的类似，但增加了一个客户数据存储功能，即服务器将存储每个连接客户所发来的所有数据，当连接终止后，服务将显示客户的名字及相应的数据。-thread safety examples. Description of the procedures for the security thread. The examples of the functions and multi-threaded server with similar examples, but the addition of a customer data storage function, which is to store each server will connect customers come in all the data, when connected after termination of service customers will show the names and corresponding data.
