What are OCX files and how to open them
Are you having problems opening an OCX file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.
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.
OCX components can be written in various programming languages and is also a way to add interoperability between programming languages. As an example, a Visual Basic program can use OCX components written in C++.
You usually do not need to edit or view these files, as they only contain information usable by the software program that uses them.
