基于ping的源代码，实现原始套接字编程(Ping-based source code, to achieve the raw socket programming)

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)

这份源码可以让大家更清晰的知道编写网络通讯的技巧(This code can let everyone know more clearly written communication network techniques)

广告墙纸.本程序包含一个发布端(把端纸发布到sql server中),客户端会自动读取墙纸,并设置为本机墙纸,还可设置图标排列方式. 目前做为机房的文告发布使用.(Advertising wallpaper. This program includes a release end (the end of the paper posted to the sql server), the client will automatically read the wallpaper, and set native wallpaper, icons arrangement can be set now to use as a room of the statement released .)

说明：  根据域名获得IP地址列表 根据域名获得IP地址列表(under the name list of IP addresses under the domain of IP address list)

实现滑动窗口协议(achieve sliding window protocols)

异步套接字编写的网络聊天室程序，根据孙鑫VC++深入详解的例子改写，使用Visual studio 2008 SP1在Unicode编码环境下编写，可以收发中文字符。(Asynchronous socket program written in Internet chat rooms, according to Sun Xin VC++ depth Detailed examples rewritten using Visual studio 2008 SP1 environment written in Unicode encoding, you can send and receive Chinese characters.)

通过此软件可以获取网页验证码，用于研究软件来控制网页中的元素信息.(With this software, you can access to the website code, used to study the software to control elements of the website information.)

一个通过网络高速传输文件的控件： 具有以下特点 1.有高速数据传输功能，超过了Winsock控件的吞吐量 2.入校验功能，满足大数据包的收发，理论上不限数据尺寸 3.加入防错代码，提高了接口鲁棒性(through a network of high-speed transmission of documents, the controls : one with the following features. A high-speed data transmission functions Controls over the throughput of Winsock 2.- Check function and meet large data packet transceiver, Theoretically Open-data size 3. to prevent the wrong code, improve the robustness Interface)

Visual C++ 6.0.此代码可以进行显示网络设置，包括IP地址等。(Visual C 6.0. This code can show network configuration, including the IP address.)
