计算校验和 校验和算法描述：为保证网络上传输的数据的可靠性，在许多协议中都设置了校验和项，例如：IPv4、ICMPv4、IGMPV4、ICMPv6、UDP和TCP 等等。计算这些校验和的算法称为网际校验和算法，简单来说就是：把被校验的数据１６位进行累加，然后取反码，若数据字节长度为奇数，则数据尾部补一个字节的０以凑成偶数。 由于从输入文件读入的数据不能直接满足计算校验和的条件，所以首先对从文件读入缓冲区的数据进行预处理，即读入缓冲区时忽略空格。由于累加是按16位进行的，所以每次从缓冲区中读出4个字符，并将字符转换成对应的16进制数字，如此依次累加，直至数据全部读完。 还有一种情况，即如果数据长度为奇数个字节，则需要判断，并补0累加。程序中利用的是缓冲区长度计数器i和当前读取到计数器j判断数据长度是否为奇数。即如果数据长度为偶数，则读完数据时当前读取到计数器j的值应与缓冲区长度i相等，而如果数据长度为奇数，则读完数据时，当前读取到计数器j>缓冲区长度i，此时需将缓冲区中剩余的两个字符读出，并补0，转换成相应16进制数以后参与累加。 当累加结束后，将累加和的16位以上数据位移下再进行一次累加，并对最后累加和取反即得所求校验和。 -calculated checksum checksum algorithm Description : To ensure the network transmission of data reliability, in many of the agreements are set up and calibration, for example : IPv4, ICMPv4, IGMPV4, ICMPv6. UDP and TCP so on. Calculating checksum algorithm called the Internet checksum algorithm, the simple answer is : as has been the calibration data for 16 cumulative, and then take the anti-code, if the data byte length of the odd, data will make up the tai

通过在远端主机上搭建一个远程字典服务服务器，其它主机可以通过客户端程序 RemoteLookup将所需要查询的单词传送给远程主机，远程主机字典服务服务器将单词的中文释义结果返回给客户端主机，在启动服务端后，即可用客户端在线查询单词，程序示范了运用没有封装的SOCKET以及Windows SDK编程的典型过程。 -Through the structures on the remote host a remote dictionary service server, other hosts can RemoteLookup client program will need to send word query the remote host, remote hosting service server dictionary word to return to the Chinese interpretation of the results to the client host, in client start-up services, you can use client-side online query word, the program has not demonstrated the use of packaging as well as the Windows SDK programming SOCKET typical process.
