实现本地程序从远程服务器下载文件。保存到本地。同时，具备断点续传的功能。可以在下载一部分的情况下，再次下载从断点处继续下载。(Implement a local program to download files a remote server. Saved locally. At the same time, with the functions of HTTP. You can download a part in the case, once again download continue downloading the breakpoint.)

VC++实现类似于QQ文件传输功能的文件发送与接收程序示例，分为服务端和客户端，客户端首次接收数据，将判断文件包大小，数据包中一定包含完整的数据包结构信息，数据不一定完整；读取数据包的大小，包含数据包结构大小和数据大小，之前接收的数据与现在接收的数据能够构成至少一个完整的数据包，文件接收完毕则设置结束标记，若终止的连接，则弹出窗口告诉用户，对方终止了文件传送。 　　服务端程序是比较简单的，基本是复制文件数据、判断文件是否传递成功、等待对方收受发送任务或取消发送任务，分包继续发送文件等功能(VC++ implementation is similar to QQ file transfer capabilities to send and receive files program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, and previously received data received data can now constitute at least one complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer. Server program is relatively simple, basically copying the file data, to determine whether the file transfer is successful, waiting for the other to accept or cancel the sending task sends tasks, subcontractors continue to send files and other functions )

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)
