摘要： 应用ＣＯＭ组件进行程序设计时，通常情况下，构件制作完成后；在操作系统中登录，然后利用在资源工厂（Ｗｏｒｋｓｈｏｐ）中注册，或在工具条上注册，开发人员就可应用该组件进行编程，然而在某些情况下，最终用户需要查找操作系统中的组件资源，根据组件提供的外部接口以及外部接口的属性和方法对组件进行选择，并在动态创建后进行调度。这就涉及到组件属性、方法的自动提取和调度．这里就是通过对组件机制和标准接口来探讨组件，进而研究ＣＯＭ件的属性、方法的自动提取和调度．

Abstract: Generally when we use component to program, it is firstly logged on OS and registered in workshop or control bar. But in some conditions it is neccssary for user to look up component's interfaces and interfacess' methods and properties available to get aeeording to his need. This paper states that how to realize automatic pick-up and invoke component's methods and propertics by detailed analysis of mechanism and standard interface of component object model (COM).
