ActiveX Control description
File extension ocx is used for Active Control items.
The ocx is an Object Linking and Embedding (OLE) custom control, a special-purpose program that can be created for use by applications running on Microsoft's Windows systems. OCX provides such functions as handling scroll bar movement and window resizing. If you have a Windows system, you'll find a number of files in your Windows directory with the ocx file name suffix.
The ocx (ActiveX control) is actually implemented as a dynamic link library DLL module. (You can think of a DLL program as a "subprogram" that can be used by any number of application programs, each of which is a "container" for the DLL or OCX/ActiveX control "object.") Visual Basic and C++ are commonly used to write OCX or ActiveX controls.
