计数器用一个开关K控制，当K=1时，可逆加法计数器进行计数，K=0时可逆减法计数器进行计数，即可构成一个具有清零和预置功能的可逆加减法计数器-counter with a control switch K, K = 1, the reversible addition counter for counting, K = 0 reversible subtraction counter for counting, with constitutes a reset and preset function of reversible counter subtract

本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行。 -This system belongs to a small local area network monitoring system that can carry out the screen of a computer monitor, this system is mainly to achieve the following features:  system uses human-computer interaction approach, friendly and beautiful interface.  screen displays information needs from time to time, the network delay can not exceed 1 second.  server-side ready to run, as long as the client is running, you can display on-screen information.  memory for the system is running can not be larger than 10MB, so as not to affect system performance.  the client run-time to hide the display window, from the feel running.

用VB开发的自动更新程序，显示下载进度，多线程下载-VB development of the automatic update, showing the progress of the download, multi-threaded Download

通过serverSocket.Accept()来接收客户Socket的连接请求，在这里用循环可以实现该线程实时侦听，而不是只侦听一次。当程序运行serverSocket.Accept()时，会等待，直到有客户端Socket发起连接请求时，获取该客户Socket，如上面的clientSocket。在这里我用多线程来实现与多个客户端Socket的连接和通信，一旦接收到一个连接后，就新建一个线程，执行ReceiveData功能来实现信息的发送和接收
