问题描述

ActiveX控件 - 小程序构建块 - 可用于创建通过Web浏览器在Internet上运行的分布式应用程序，例如用于收集数据，查看某些类型的文件和显示动画的定制应用程序。 （wikipedia）

is an Object an instance of a Control?

推荐答案

p> MS术语不清楚，特别是因为ActiveX是一个营销术语而不是技术术语。通常，ActiveX可以替换为COM，以给予更技术上可理解的意义。

The MS terminology is unclear, especially since ActiveX is more a marketing term than a technical one. Often, "ActiveX" can be replaced with "COM" to give a more technically comprehensible meaning.

ActiveX / COM中的所有代码最终都是暴露一个或多个接口的对象。因此，ActiveX / COM控件是对象，以及其他可插入的COM类型，例如Explorer扩展，浏览器帮助对象等。

All code in ActiveX/COM ultimately is an object that exposes one or more interfaces. So, ActiveX/COM controls are objects, along with other pluggable COM types, such as Explorer Extensions, Browser Helper Objects etc.

对于被认为是ActiveX控件，它必须实现控件嵌入容器所需的一组接口。 IViewObject，IOleControl，IOleControlSite等。

For an object to be considered an ActiveX control, it must implement the set of interfaces needed for the control to be embedded in a container. IViewObject, IOleControl, IOleControlSite etc..
