一个使用socket写的telnet的客户端

Client程序同样分别创建一个TCP socket 和一个UDP socket，首先client使用TCP socket连接TCP Server。 连接成功后显示提示信息； 然后client端向TCP Server发送“GET UDP PORT”字符串，Server收到后向client回送自己的UDP Server 端口号（即Client端仅知道TCP Server的端口号而不知道UDP Server的端口号）； client在收到UDP Server的端口号后, 为用户显示3个选项： 1．“Get current time（TCP）”服务器时间 2．“Echo Mode（UDP）”回显6 3．“Exit the program”. -Client program also creates a TCP socket, respectively, and a UDP socket, the first client to use TCP socket connection TCP Server. After a successful connection displays a prompt message and then client-side to the TCP Server sends " GET UDP PORT" string, Server receipt back to the client to send their UDP Server port number (ie, Client-side only to know the TCP Server" s UDP port number do not know Server" s port number) client received UDP Server port number, in order to the user three options: 1. " Get current time (TCP)" server time 2. " Echo Mode (UDP)" echo 63. " Exit the program" .

利用CSocket实现远程桌面功能。程序有点复杂，主要是CSocket的运用。 实现思路主要是：先将远程桌面捕获发回本地，然后在对话框中显示，将本地鼠标、键盘的动作变成命令输入，再发送到远程主机执行（实际上这一步是模拟出鼠标和键盘的操作），最后将远程桌面再次捕获发回本地，在对话框中显示出来。这样也就实现了系统自带的远程桌面的功能。-Use CSocket remote desktop functionality. Process a bit complicated, mainly the use of CSocket. To achieve the main idea is: first issued back to the local Remote Desktop Capture, and then in the dialog box shows that the local mouse and keyboard moves into a command input, and then sent to the remote host implementation (actually, this step is to simulate the mouse and keyboard operation), and finally re-captured the remote desktop back to the local, in the dialog box is displayed. This also enables the system comes with remote desktop functionality.
