New Active Technologies

Active Technology includes many features that don't overlap or extend older OLE technologies. Many of these technologies facilitate the creation of interactive applications for the World Wide Web. These items are

• ActiveX hyperlinks
• NetShow, previously known as ActiveX Conferencing
• Code signing
• HTML extensions
• ActiveMovie

Active Hyperlinks

Active hyperlinks basically allow in-place activation from HTML files of non-HTML–based documents. Using an Active document container, you can access Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Visio, and CorelDraw! documents from a hypertext link in an HTML document.

NetShow

The NetShow services are a suite of technologies that enable real-time, multiparty, multimedia communication over the Internet. This is much like video teleconferencing except you can do it on a PC. Just think what this does for programmers; we could all work at home and telecommute. This is a programmable interface opening up endless possibilities for innovation.

Active Scripting

Active scripts bring Automation to a wide range of areas, such as Web Servers, Network management, and even applications such as SQL Server. Any application that supports Active Scripting will accept scripts written in any scripting language supported by an Active scripting engine. Windows includes support for JavaScript and VBScript. Third-party scripting engines are available for Perl and LISP.

Code Signing

Code signing is a new technology that enables electronic signatures for code. This provides security from tampering of interactive applications across the net. Basically, the application vendors will provide a digital signature for their code that complies with the code signing specification. On the client side, when an application or component is downloaded from the net, it calls a Win32 API function called WinVerifyTrust(). This function checks the digital signature and verifies it.

HTML Extensions

Hypertext mark up language (HTML) is the language for all Web-based document production. In order to support ActiveX controls, extensions had to be made to the HTML language. In addition, Web browsers had to be modified to accommodate the new language extensions. Now you can add ActiveX controls to Web pages using the HTML <OBJECT> tag.

ActiveMovie

ActiveMovie is a new technology to replace the old Media Control Interface and Video for Windows. ActiveMovie is an audio- and video-streaming framework. With ActiveMovie, you will be able to play back MPEG, AVI, and Apple Quicktime movies.
