What Is Activex: What Does Activex Do? Benefits of Activex
Khalil Rehman December 2, 2003 What is ActiveX: Microsoft® ActiveX™ is a set of technologies from Microsoft that enables interactive content for the World Wide Web. With ActiveX, Web sites come alive with multimedia effects, interactive objects, and sophisticated applications that create a user experience comparable to that of high-quality CD-ROM titles. ActiveX provides the glue that ties together a wide assortment of technology building blocks to enable these "active" Web sites. (Microsoft Corporation, July 1996) What does ActiveX do? It is designed to increase the dynamic designs of a website. The controls are components that can easily be inserted into a Web page or other application to reuse packaged functionality someone else has programmed. Benefits of ActiveX Some benefits of ActiveX are, • Active web content which attracts the user and retain their interest in the web pages. • Open cross platform support on Macintosh, Windows and Unix operating systems • The tools in which programmer wants to build ActiveX controls are very common and familiar like Visual Basic, Visual C++®, Borland Delphi, Borland C++, Java™, and Java-enabled tools • Existing inventory of ActiveX controls available today for immediate use by Web producers ActiveX VS Java ActiveX is a Microsoft platform dependent and works on window based machine and only work in the internet explorer browser. Once ActiveX controls install and run on the machine it doesn’t need to install and run again, saving the download time after first use. Java has been developed to work on any kind of machine and operating system and do not need of any kind of plug-in. -
