ASP应用中COM组件开发方法研究

The Methodological Research on Applying COM Technique to ASP

  • 摘要: 从ASP技术与COM技术出发,针对MCU远程控制应用的多层分布体系结构特点及应用要求,详细论述了如何进行组件线程类型选择、接口设计、物理定位开发与实现具有特定功能的COM组件并如何在ASP应用中创建和执行,以实现远程控制MCU功能。论述了在设计与实现COM组件过程中,其安全性与作用域的选择。

     

    Abstract: MCU(Multi-point Control Unit) is the key equipment of multi-point video conference.Multi layer network connected with multi MCUs can implement large-scale video conference.Because of their characteristic of unbounded geographical zone,multi MCUs are set on each floor in a building or at another office building,or different zones.It brings about the problem how to manage and control dispersing MCUs.Creating system of controlling MCUs in long-distance is the optimal scheme to solve this problem.This paper analyzes not only the characteristic of multi-layer distributed system structure provided by the system of controlling MCUs in long-distance,but also the special requests in application of the Internet.The methods to select thread type of component,design interface,arrange component physical location and test component in idiographic application condition are introduced.And how to unite COM and ASP to create COM components in ASP applications is discusseed in detail.Using the technology in the paper,programmer can set up greater Internet applications.They have good performance and multi-user.At last,how to select COM's security and its lifecycle in COM's design and realization is discussed.
