ActiveX controls replaced the earlier Object Linking and Embedding, known as OCX, custom-level controls.Īn ActiveX control is roughly equivalent in concept and implementation to the Java applet. These technologies are based on the Component Object Model (COM), an interoperability standard for building reusable software libraries that can interact at runtime. What do ActiveX controls do?ĪctiveX controls are part of Microsoft's overall ActiveX technology. The IE Tab add-in makes it possible to use ActiveX controls within Chrome. This is a Chrome extension that displays webpages using IE. One example is the Google Chrome browser, which offers the IE Tab add-in.

By using ActiveX controls, developers can implement commonly performed operations across many applications without having to redevelop the code for each instance.ĪctiveX controls are supported in other ways. For instance, a developer might add an ActiveX control to a Word document that lets users fill out a form in the document. In addition to web applications, other types of Windows applications - such as Microsoft Word and Excel - can use ActiveX controls.
