Chapter 8 -- ActiveX Technologies

ActiveX is a COM-based technology that provides the fundamental building blocks used in most Windows applications. ActiveX can be used to create controls, documents, and components that run on desktops or the Internet. ActiveX components can be developed in many programming languages, including all of the Microsoft application development products.

ActiveX technology was derived from object linking and embedding (OLE) technology. ActiveX controls were originally called OLE controls. ActiveX controls, commonly called custom controls, are among the most powerful building blocks for creating applications.

ActiveX controls are reusable objects that include visual elements and code. They are used in some type of container, such as a form or an application, to enable or enhance a user 's interaction with an application. These controls have an .ocx file name extension.

ActiveX controls can be used in many types of applications, such as Microsoft Office, Microsoft Internet Explorer, and Microsoft Visual Basic. An ActiveX control can be contained within a Web page, but ActiveX controls are not limited to the Internet.
