ActiveX is a set of programming technologies created by Microsoft that enables software components created in different languages to interact with one another in a networked environment. It evolved from the OLE development standard, which in recent years has expanded far beyond the concepts of object linking and embedding that formed the original acronym.
Most MMI/SCADA software are a container for ActiveX controls.
ActiveX is an umbrella term of a broad range of technologies that used to be known as OLE Controls, all of which rely on COM.
A renaming and restructuring of the OLE Controls technology, it is object-based rather than object-oriented.
ActiveX is an open, integrated platform that lets developers and Web producers create portable applications and interactive content for the World Wide Web.
Itâ€™s open, cross platform, and is supported on Mac,Windows, and Unix systems.
