COM中自定义接口的实现

The realization of COM's custom interface

COM是一种与操作系统和语言环境无关的软件构架,它将各功能模块通过接口组装起来来构成软件系统,这种系统便于设计、维护和升级。本文简单介绍了COM接口的特点、概念,详细阐述了自定义接口的实现方法以及进程外组件如何使用自定义接口。

COM is an operation system and software enviroment independent structure,It assembles the functional moduls through their interfaces to construct the software system,This makes the system easy to design,to mantain and to upgrate. The paper explores the characteristics,conceptions of COM interface,with an emphesis on the realization method of the custom interface and the usage of custom interface in out-procedure components.
