UDT网络传输协议开源包，是基于UDP的可靠传输协议，支持P2P，有现成的文件传输函数，速度比TCP快。(Open source packages of the UDT network transport protocol is UDP-based reliable transport protocol to support P2P, there is a ready-made file transfer function, the speed is faster than TCP.)

说明：  定义了一个用于控制扭转和弯曲周期运动的udf程序，用于计算fluent中动边界案例。(A UDF program is defined to control the periodic motion of torsion and bending, which is used to calculate the dynamic boundary case in fluent.)

返回的qq基本信息有：(联系地址,用户年龄,用户邮箱,头像,个人网站,职业,邮箱,联系电话,简介,省份,真实姓名,毕业院校,性别,QQ号,昵称)

Linux系统编程，调用接口获取设备IP地址(Linux system programming, call the interface to get the device IP address)

【实例简介】用C#做的车牌识别的软件，供参考

说明：  /** * 动态数组的模板类 * 1.支持字符索引 * 2.方便的添加删除修改任意一项 * 最后更新 2004-8-9 yzh **1.优化了字符索引的运作方式，使用数组存储 **2.重写了底层数据的存储，将连续性的存储方式改为了非连续, *** 从而很好有效地支持了“引用”,并且让数据的删除增加变的更为快速 * 用法如： * YCArray<int,int> test * test.Add("Number2",4) * test.Add("Number1",2) * printf("%d %d",test["Number1"],test["Number2"]) * 显示： * 2 4 ******* ******* History: 2004-11-19 修改了析构函数,解决了索引没有释放的bug **/(/*** dynamic array template class* 1. Support characters Index* 2. Add convenience to delete arbitrary* a final update 2004-8-9 yzh** 1. Character Index optimized mode of operation, the use of storage arrays** 2 . a rewrite of the underlying data storage, storage continuity conversion of non-continuous, and thus good*** effective support to the "quote", and let the data changed to delete the more rapid* usage such as :* YCArraylt; int, intgt; test* test. Add ( "Number2", 4)* test.Add ( "Number1", 2)* printf ( "% d% d", test [ "Number1"] test [ "Number2"])* Display :** 2 4************* History : 2004-11-19 revised the destructors, the index did not address the release of bug** /)

用vc实现邮件传输功能，主要采用winsock实现传输过程。有利于熟悉网络编程。(achieved using vc mail functionality, mainly winsock achieve transfer process. Help familiar with network programming.)

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

是个实现简单抓包，在运用于网络或单机中的实现。(is simple-capturing Packet achieved in networks or single-board computers used in the implementation.)
