.OCX

📌 The .OCX extension foundation is oriented towards a reusable software module, recognized as an ActiveX control, which can be repeatedly used within multiple Windows tools and services. Indeed, ActiveX .OCX bundled file controls can be generated, opened up, and applied for various purposes, such as multimedia viewers, online games, web-page widgets, and user interface forms.

A huge arsenal of .OCX data file samples are included with the basic Windows distribution set, while others are shared by various software installers. In order for a relevant software suite to open and use a requested .OCX tailored ActiveX file control, the .OCX file control should be initially registered in Windows with Regsrv32.exe executable file library. Hereby, pinpoint software installers may embrace .OCX wrapped ActiveX control registration as a final iteration in the installation routine.

Software developers are accustomed to building up and deploying .OCX ActiveX file controls with such tools as Microsoft Visual Studio using custom programming techniques, such as C++ and Visual Basic languages. When packaging a respective .OCX file control, developers define events, methods, and properties for the corresponding control according to Microsoft’s Component Object Model (in short, COM) pattern methodology. The eventual definition can be accessed by other software suites as long as the control is initially registered in Windows architecture.

Warning: Nowadays ActiveX principle is not commonly applied for distributing and designing composite software modules. However, ActiveX controls are still compliant with Windows 10 infrastructure via Internet Explorer 11 and manual registration routine.

How to open an .OCX file?

📌 The .OCX file hierarchy and composition are perfectly operated, opened, and sustained by Microsoft Visual Studio SDK belonging to either legacy or present-day editions.
