ActiveX Document
（重定向自ActiveX Documents）
ActiveX Document (also known as DocObject or DocObj) is a Microsoft technology that allows users to view and edit Microsoft Word, Excel, and PDF documents inside web browsers. It defines a set of Component Object Model coding contracts between hosting programs like Internet Explorer or Microsoft Office Binder and hosted documents from programs like Microsoft Word, Microsoft Excel or Adobe Reader. This allows them to negotiate communications about commands like save and navigate, as well as merging user interface elements such as menu, to provide an unified user experience.
