大家共享好东西， 尤其是学C++的出血者(share good things, especially learning C bleeding)

我的毕业设计，一个简单的集聊天，文件传输于一体的vc源码，可选TCP或UDP传输模式！(My graduation project, a simple set chat, file transfer in one vc source, optional TCP or UDP transfer mode!)

说明：  如何开发OPC Server.OPC主要适用于过程控制和制造自动化等应用领域。(this paper teach us how to make OPC Server.The main useful to use OPC is contoel.)

仿造QQ写的一个聊天程序，用于学习网络编程， 熟悉网络编程的知识(Fake QQ write a chat program for learning network programming)

聊天程序的源码，对学习socket编程很有帮助。(Chat program source code, useful for learning socket programming.)

通过微过滤器的方式实现的网络控制功能，简单实现了一下禁止当前机器断网的功能。(Through micro-filters to achieve the network control functions, simple look prohibit the machine off the network.)

一般地，把三角形的三个角A，B，C和它们的对边a，b，c叫做三角形的元素。已知三角形的几个元素求其他元素的过程叫做解三角形。解三角形，常用到正弦定理和余弦定理和面积公式等。正弦定理a/sinA=b/sinB=c/sinC=2R（2R在同一个三角形中是恒(The Triangle software, wrote)

驱动层抓取网卡数据代码，并可以修改数据包内容(Crawl layer data-driven card code, and can modify the contents of data packets)

tcp查看器，可以查看tcp协议的相关信息，还包括设置，等等，对学习tcp协议有很大帮助(tcp viewer, can view information about tcp protocol, but also include the provision, and so on, to learn tcp protocol has very helpful)

孙鑫VC++教学课程lesson14：网络的相关知识，网络程序的编写，Socket是连接应用程序与网络驱动程序的桥梁，Socket在应用程序中创建，通过bind与驱动程序建立关系。此后，应用程序送给Socket的数据，由Socket交给驱动程序向网络上发送出去。计算机从网络上收到与该Socket绑定的IP+Port相关的数据后，由驱动程序交给Socket，应用程序便可从该Socket中提取接收到的数据。网络应用程序就是这样通过socket进行数据的发送与接收的。TCP与UDP的工作原理与编写过程，如何在程序中链接库文件。一个字符界面的聊天程序。(Sun Xin VC++ tutorial lesson14: the knowledge of the network, network program, Socket is connected applications and network drivers bridges, Socket application to create, build relationships bind driver. Thereafter, the data of the application to give socket, by the Socket handed driver and sent out on the network. After binding with the Socket IP+Port related data is received by the computer from the network, by the driver to the socket, the application can extract the data received from the Socket. Network application is sending and receiving data through the socket. TCP and UDP works and the writing process, how to link library files in the program. A character interface chat program.)
