基于ActiveX技术的PPT无线演讲新方案的设计与实现

摘要

通过研究PPT演示文稿各种常用操作和VBA代码之间的对应关系,开发得到VB ActiveX控件,利用VC平台编写Winsock网络通信程序,两者结合再基于无线路由器便可得到对PPT进行操作的无线演讲方案.组网实验表明,此方案大大改进了传统PPT演讲的缺陷,加之演讲者使用平板电脑,更能显出它的优越性.%Through the corresponding relationship between PPT common operations and VBA code, the VB ActiveX controls are developed, and the Winsock network communication programs using VC platform are written. Then combining this two parts, the PPT wireless speech scheme with a wireless router is got. The networking experiments show that the defects of the traditional PPT speech are improved greatly. Its advantages are more obvious if the lecturer uses tablet PC..
