摘　　要：提出一种基于Winsock通信的远程抓屏功能的实现方法。采用C/S模式,基于TCP协议进行通信,Client端调用Winsock发送截取屏幕的命令,Server端接收命令并运用Windows API函数和Winsock实现屏幕的抓取和远程数据传送;使用柯达公司的ImgEdit控件对截屏后的图像文件进行压缩,便于数据的传输;实验结果表明,该方法能方便、快捷地实现远程计算机的屏幕抓取,为远程智能监控的发展提供一种有效的软件实现方法。This article put forward a new method to realize remote screen scraping based on Winsock. By adopting C/S mode and TCP protocol, the Client-side sent the relevant control command to Server-side and then by using the Windows API function and Winsock, the screen scraping and remote data transmitting can be done. The use of ImgEdit control of Kodak can compress the screenshot image file for transmitting data quickly and correctly. Finally, the experiment result showed it was convenient and fast to realize remote computer scraping by using this method and it could provide an efficient software for remote intelligent control.
