All about ActiveX

ActiveX is basically used to define reusable software components, these perform a particular function or a set of functions in Microsoft Windows. It was introduced in 1996 by Microsoft and is commonly used in the Windows Operating System. You will find that many of Microsoft Windows applications such as Internet Explorer, Microsoft Office, Windows Media Player, Visual Basic etc, use ActiveX to control and function their own built in features. Programmers can develop ActiveX controls in a variety of languages, including C,C++, Java and Visual basics. They are similar to Java applets, but they have complete access to the Windows operating System. Giving them more function ability and power, thereby more risk. Hence there is a certain registration system in Microsoft, that enables users to identify if the ActiveX is genuine and then download it. Another major difference between Java applets and ActiveX controls is that, Java can basically run in almost any given platform, whereas ActiveX can run only in the windows.

A control designer can digitally sign the controls with the help of a signature authority that makes the signature authentic. Later on, when you visit a web page that uses this control, your browser can verify that the control was actually written by the person who signed it. This does not completely guarantee that the control is 100% safe, but at least you have some hope that you know who really wrote the control. This is most significant when someone copies a control from one website to another. The signature helps you verify who the original author was, and from where it originally came.
