类似QQ的全套聊天系统

qq程序 可以选择UDP 和TCP 实现发送信息 和 传输文件 (the qq procedure to send messages and transfer files)

说明：  trdp列车实时以太网通信协议，源自tcnopen，基于tcp/ip协议栈开发，非常方便移植与应用开发；(TRDP based on tcp/ip stack;)

说明：  为解决实际测控系统中在控制中心的上位机和控制功能设备的下位机之间传送命令和文件的问题,在讨论VC++6.0中MSComm控件的基础上,通过制定通信协议、给命令和文件加入标识构成包进行传送,从而正确地区分了命令和文件.实验表明,基于该通信协议,可以成功地传送命令和多类型文件. (To address the actual measurement and control system in the Control Center PC and control functions of equipment under the digital transmission between orders and documents, in discussing the VC++ 6.0 in MSComm control on the basis of the communication protocol through the development to the orders and adding logo files constitute a packet transmitted, thereby correct distinction between the orders and documents. The experimental results show that based on the communication protocol, you can successfully send a command and multi-type documents.)

基于VC++开发的VNC服务端，非常有用方便，可用于远程调试使用(Developed based VC++ VNC server, very useful convenience for remote debugging)

说明：  用VC开发的C语言编写的MD5程序源码,作为开发md5的参考(The source code of MD5 program written in C language developed by VC is a reference for developing md5.)

这是一个关于MODEM的网络编程源代码，采用VC++编写。(This is a MODEM network programming source code, written using VC++.)

网页嵌套的pdf组件，可以在网页中嵌套自己开发的pdf组件(Web nested pdf components can nest pdf components to develop their own web page)

为网络通信提供安全及数据完整性的一种安全协议，囊括了主要的密码算法、常用的密钥和证书封装管理功能以及SSL协议，并提供了丰富的应用程序供测试或其它目的使用。(The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing ... )

期望最大化MLE算法(MLE.m)

EZ-IPUPDATE的LIB7版本，极有参考价值，与3322的QDNS不完全相同(ez-ipupdate is a small utility for updating your host name for the any of the dynamic DNS service offered at: * http://www.ez-ip.net * http://www.justlinux.com * http://www.dhs.org * http://www.dyndns.org * http://www.ods.org * http://gnudip.cheapnet.net (GNUDip) * http://www.dyn.ca (GNUDip) * http://www.tzo.com * http://www.easydns.com * http://www.dyns.cx * http://www.hn.org * http://www.zoneedit.com )
