一个简单的vc下tcp服务器端程序服务器端的程序当有客户提出连接请求时，在端口与客户端进行连接，连接成功后，显示客户IP地址和端口号，并给客户端发送“Hello!I am a server.”字符串。如果发送正确则显示所发送的字节数-Vc under a simple tcp server-side server-side program when connection requests made by the customer, in the port and connect the client to connect successfully, the display client IP address and port number, and to the client to send

Recognition of characters greatly depends upon the features used. Several features of the handwritten Arabic characters are selected and discussed. An off-line recognition system based on the selected features was built. The system was trained and tested with realistic samples of handwritten Arabic characters. Evaluation of the importance and accuracy of the selected features is made. The recognition based on the selected features give average accuracies of 88 and 70 for the numbers and letters, respectively. Further improvements are achieved by using feature weights based on insights gained from the accuracies of individual features.

TCP的客户服务器通信程序 一：程序运行过程 1、运行服务器程序，等待客户端发出请求 2、运行客户端程序，输入客户的IP地址，请求连接 3、若连接成功，服务器端显示客户的IP地址及端口号；客户端接收文件并保存在d:clientls.txt下，否则，显示错误信息。 二：程序实现原理 发送端：打开文件，逐一读取字符到缓冲区（缓冲区大小为1024），若文件大于1024，则成块发送；若小于，则直接发送。 接受端：与发送端同理。-TCP client-server communication program one : running a process, running the server and wait for the client to issue two requests, the client operating procedures, the importation of customer IP address, link request, if successful connection, the server-client shows the IP address and port number ; the client receives the document and preserve d : client ls.txt, otherwise an error message. 2 : Principle procedures transmitter : open the file, read each character to the buffer (buffer size for 1024), and if the document is greater than 1,024, then sent into pieces; If less, then sent directly. Receivers : Send-the same reason.

要在相同的网络终端上绑定到不同的套接字上，所以必须为这些套接字设置SO_REUSEADDR属性（即允许重用），否则侦听会失败。 4、S的【协助打洞】连接收到A的申请后通过【主连接】通知B，并将A经过NAT-A转换后的公网IP地址和端口等信息告诉B。 5、B收到S的连接通知后首先与S的【协助打洞】端口连接，随便发送一些数据后立即断开，这样做的目的是让S能知道B经过NAT-B转换后的公网IP和端口号。 6、B尝试与A的经过NAT-A转换后的公网IP地址和端口进行connect，根据不同的路由器会有不同的结果，有些路由器在这个操作就能建立连接，大多数路由器对于不请自到的SYN请求包直接丢弃而导致connect失败，但NAT-A会纪录此次连接的源地址和端口号，为接下来真正的连接做好了准备，这就是所谓的打洞，即B向A打了一个洞，下次A就能直接连接到B刚才使用的端口号了
