文章提出了根据电子虚拟实验室系统的功能要求进行架构的方案,利用三层C/S模式实现系统总体框架的搭建。在该架构模式下根据Winsock的通信机制,利用VC++的MFC_CSocket类实现服务器与客户端的网络通信连接,同时实现系统中所要求的在线答疑功能的设计。经测试,这种网络通信的设计较成熟稳定,能够实现设计目标。 The article puts forward a scheme of architecture based on the functional requirements of the electronic virtual laboratory system, and uses the three-layer C / S model to build the overall system framework. According to Winsock’s communication mechanism in this architecture mode, the MFC_CSocket class of VC ++ is used to realize the network communication connection between the server and the client, meanwhile, the design of the online answering function required in the system is realized. After testing, this network communication design more mature and stable, to achieve the design goals.
