一个完整的网吧管理程序,美国人写的.

rc4 java 实现-rc4 java realizes

模拟DCS数据发包数据环境，UDP，在电厂做工程时因为不能随便接触控制网络，所以写了这样一个模拟DCS向外发布数据的程序，方便在开发环境进行调试。-UDP ，imitate DCS（Distribute Control System）output data circument。

使用JAVA I/O和 NI/O编写的两种网络ECHO服务器，用以学习两种IO的不同编程方法，体验基于阻塞与非阻塞IO开发高性能网络应用程序的具体实例.Java平台传统的I/0系统基于byte(字节)和Stream(数据流)。这种模式下的I/O 操作以字节为单位,以流的方式处理数据。而NIO( New I/O )以块的方式处理数据，它的系统操作面向Buffer(缓冲),Channel(通道)和Selector(选择器)，不再是字节，这种模式利用了操作系统管理内存和文件的方式，并将一些耗时操作直接转移给操作系统，使JavaI/O的速度得以提高、性能得到了明显的改善 -The use of JAVA I/O and NI/O, prepared by two types of network servers ECHO to learn two different programming methods IO experience obstructive and non-blocking IO based on the development of high-performance network applications specific examples. Java platform for the traditional I/0 system is based on the byte (byte) and Stream (data streams). This mode of I/O operation in bytes in order to deal with data flow way. The NIO (New I/O) blocks the way to deal with data, its system for Buffer (buffer), Channel (channel) and the Selector (selector), is no longer a byte, this mode of use of operating system management of memory and the manner in which documents, and some time-consuming operation of a direc

这是一个使用32位汇编语言写的一个PING程序，就像是在windows命令行下的ping命令一样。-It is a compilation of 32 languages written in a PING procedures, it is like the windows command line under the ping orders.

里面主要是JAVA开发的一个企业内部通讯软件，的源码-Which is mainly the development of a JAVA enterprise communications software, source code

国网表抄表设置软件,通讯协议为DLT645-2007，目前网络上唯一一份国网表的设置抄表用软件-State Grid Meter Reading set up the software, telecommunications agreement DLT645-2007, is currently the only network in a country setting netlist meter reading software

用套接字的方式连接2个电脑，之后在一方电脑上画图，另一方电脑可以实时显示-Way to use sockets to connect two computers on one computer after the drawing, the other computer can be real-time display

WIN32 API写的第一个函数,只是传一个字符串就结束了,但是体现了socket的连接建立过程-WIN32 API to write a function of just one-on the end of a string, but the embodiment of the socket connection establishment process

网络方面关于ip的得到与获取方面的代码，哈哈哈 -ip on the network and get access to the area code, Ha Ha Ha

检测Windows自带的防火墙是否启动类。用到COM，学习参考用-Detect Windows own firewall whether to activate the category. Use COM, study reference
