What is an OCX file?

An .OCX file is a Windows ActiveX Control file.

OCX is short for OLE Control Extension, a software component technology from Microsoft. Using this standard, it is possible for developers to use features from OCX modules from their own applications. For example, a developer could purchase an OCX PDF Viewer component to add PDF viewing capabilities to his document processing application.
