Abstract: Based on the Socket communication, this paper uses the program technology of MFC and SDK to obtain the remote machine’s screen and realize the control function. In the paper, the interface of client use MFC, and the server use SDK, this design can realize the interface of client expediently, and adapt for the requirement that the server not need interface but socket communication.

摘要： 采用Socket套接字通信，使用MFC与SDK混合编程技术，完成远程截取目标机屏幕并实现本地机对目标机的控制功能。其中，本地机界面使用MFC，目标机使用SDK，这种实现方案既方便本地机作为客户端控制界面的实现，同时又满足目标机作为服务端无需界面、仅实现Socket通信的要求。
