Modbus协议，串口读取short,ushort,int,char

程序利用多线程技术和socket技术实现网上聊天程序。服务器程序和客户端程序在同一程序里。(This program realizes the chatting fuction using the multithread technique and socket programming.)

本程序是采用udp协议实现了简单的聊天室，包括客户端和服务端，客户端发送消息到服务端，服务端将接受到的消息分发到所有的客户端实现简单的群聊。

该代码展示了如何利用完成端口配合异步I/O开发可扩展服务端。(The code demonstrates how to complete port with the use of asynchronous I/O can be expanded development of the server.)

When I wrote this function my problem was to replace one color by an other on transparent bitmaps My

说明：  高效服务器编程模型，达到理论100W并发服务(Efficient Server Programming Model)

实现了图片轮播的功能，只需要调整样式就行，轮播的当前页也显示了的(Realized the function of the picture rotation, only need to adjust the style, the current page of the wheel is also displayed.)

实现通用的程序升级功能，可以检查是否有更新，下载更新(Achieve universal upgrade feature, you can check for updates, download updates)

说明：  点对点的聊天工具，公司不让QQ,SKYPE，就动手写了个超小巧的聊天工具(Peer-to-peer chat tool company from QQ, SKYPE, on hand to write a super-compact chat tools)

用于无线网络编程的学习,很实用，作为初学者的入门教材还是很有用的。(Wireless network programming for learning)
