UDP_Lost_test2

基于udp的服务器与客户端之间传输字符串(Udp-based server and the client to transfer a string)

基于TCP/IP协议的MFC网络编程实例，适合windows网络编程的初学者(MFC network programming example based on TCP/IP protocol, adaptive for whose who starts to learn Windows network programming.)

socket编程实现服务端与客户端互发消息(exchange message between server and client)

说明：  在Internet上的聊天室程序一般都是以服务器提供服务端连接响应，使用者通过客户端程序登录到服务器，就可以与登录在同一服务器上的用户交谈，这是一个面向连接的通信过程。因此，程序要在TCP/IP环境下，实现服务器端和客户端两部分程序。(In Internet chat rooms on the procedure is generally based on the server side connection in response to the provision of services, the user through the client program to log on to the server, you can log in the same server with the user to chat, this is a connection-oriented communication process. Therefore, procedures to TCP/IP environment, the realization of server-side and client procedures in two parts.)

vc++ Socket编程入门程序，容易上手，入门首选，才用UDP方式，客户端(vc Socket Programming induction procedures, easier to get started, beginners choice before using UDP, the client)

简单放大镜，生成一个放大窗口，滚轮实现倍率调节(Simple magnifier generates an enlarged window, and the roller realizes magnification regulation)

VC++ 2008客户端实现 可以模拟多个服务器链接(VC++ 2008 client implementation can simulate multiple servers link)

一个监控网卡的程序。功能如果网卡掉线，电脑自动关机(A monitoring procedure for the network card. Function if the network card offline, the computer automatically shuts down)

说明：  基于VC++的局域网聊天室，能够实现多人房间聊天。(LAN chat room based on VC++ can realize multi-room chat.)
