论述了区域森林资源预警技术系统开发的核心技术之一的ＡｃｔｉｖｅＸ技术。从ＡｃｔｉｖｅＸ与软件危机关系的角度，讨论了ＡｃｔｉｖｅＸ组件技术的重要性，并对ＡｃｔｉｖｅＸ组件技术的基本原理及其开发工具的支持情况作了简单介绍。举例说明了预警技术系统开发中ＡｃｔｉｖｅＸ组件的创建和应用，并且比较了与ＡｃｔｉｖｅＸ相互竞争的２种技术：ＣＯＲＢＡ和ＪａｖａＢｅａｎ。
This paper discusses the ActiveX technology, one of the core technologies in the development of regional forest resources early warning technology system. From the point of view of the relationship between ActiveX and software crisis, this paper discusses the importance of ActiveX component technology and gives a brief introduction of the basic principle of ActiveX component technology and the support of its development tools. An example is given to illustrate the creation and application of ActiveX components in the development of early warning technology system. The two technologies that compete with ActiveX are compared: CORBA and JavaBean.
