Background
-
Active X is a type of technology created by Microsoft that is used for developing programs and applications for websites.
Identification
-
A file with the .OCX file extension is known as an Active X control file.
-
Function
-
A file with the .OCX file extension contains instructions that your computer follows to perform a part of a task associated with an Active X file.
Features
-
OCX files serve a variety of purposes, such as powering the scroll bar at the side of a website application. OCX files are typically written in either the C++ or Visual Basic programming languages.
Considerations
-
An OCX file is typically embedded within a larger Active X control file, but is saved to a server so that it can be easily accessed when the web application is displayed. Because OCX files are necessary for a program to function correctly, never delete these files from the server.
