- Accessibility
Accessibility is the process through which Web sites accommodate the needs and preferences of all users, taking low vision, color blindness, deafness, language impairments, and restricted mobility into account. Web sites that meet accessibility requirements are also compatible with accessibility aids, such as speaking tools that enable blind users to access sites with a speech reader, and voice input utilities and on-screen keyboards to permit the user to choose from a list of available commands and objects.
- Active Channel technology
Active Channel™ technology is used to create specialized Web sites developed for online content subscriptions and automated content delivery. Using a Channel Definition Format (CDF) file, these specialized Web sites allow Web authors to determine how and when information is accessed. By subscribing to an Active Channel that utilizes CDF files, the user can be notified when the content has been updated, and the content can be delivered directly to the user's computer for offline reading. Content can be delivered in a variety of ways: in full-screen mode, as a screen saver, on the computer desktop, or via e-mail.
- Active Desktop
The Active Desktop™ interface, installed with either standard or full installation of Microsoft Internet Explorer 4.0 or later, integrates the browser software with the rest of the Windows operating system. In its most basic form, it consists of both Windows icons and HTML elements placed on the computer desktop. The Active Desktop comprises two layers, the icon layer and the HTML layer. The transparent icon layer displays the user's existing desktop shortcuts, while HTML-based items, such as ActiveX controls and scripts, are hosted on the background HTML layer.
- Active Desktop item
An Active Desktop™ item is a small Web page or HTML component, such as an ActiveX control, a Java applet, or DHTML, that is displayed on the Active Desktop of Internet Explorer 4.0 or later. An Active Desktop item can be created from an existing Web page, or one that has been created for that purpose. Once added to the Active Desktop, the Active Desktop item can be personalized by the user; options include size, position, and adding or removing the frames.
- Active Document
Also known as Document Objects or Doc Objects, an Active Document is a Windows-based, non-HTML application embedded in a browser, so it is accessible from within the browser's interface. Microsoft Internet Explorer is an example of an Active Document container. Microsoft Word is an example of an Active Document server. To see a demonstration of an Active Document, open a Word document from within Internet Explorer. The displayed Word document appears just as it would if opened in Word, except that it is contained inside Internet Explorer. Internet Explorer provides the basic menus, toolbars, and status bars, but Word adds its own menus, toolbars, and status bars to the user interface.
- ActiveMovie Control
- Active Server
The Active Server is a collection of server-side technologies that are delivered with the Windows NT operating system, and provide a consistent server-side component and scripting model, as well as an integrated set of system services for component application management, database access, transactions, and messaging. Using this server-side and script-based programming model, developers can create server and Web server applications.
- Active Server component
Active Server components are OLE Automation components designed to run on the server side as part of a Web application. These components are activated through Active Server Pages (ASP) technology but don't require a Windows interface.
- Active Server Pages (ASP) technology
ASP technology provides an open, compile-free application environment in which Web developers can combine HTML, scripts, and reusable
Active Server components. ASP technology enables server-side scripting for IIS with native support for both Visual Basic Scripting Edition and JScript.
- Active Template Library (ATL)
The ATL is a set of template-based C++ classes. With ATL, you can create objects and specify the threading model: single, apartment, free, or both. Single-threaded objects, apartment-model objects, free-threaded model objects, and both free-threaded and apartment-model object can all be created using ATL code. ATL simplifies the programming of Component Object Model (COM) objects by providing special support for key COM features, such as stock implementations of IUnknown, IClassFactory, IClassFactory2, and IDispatch; dual interfaces; standard COM enumerator interfaces; connection points; tear-off interfaces; and ActiveX controls, allowing developers to focus on the functionality of the object.
- ActiveX
ActiveX™ is a set of technologies that are built on the Component Object Model (COM), and enable software components, regardless of the language in which they were created, to work together in a networked environment. Although ActiveX technologies are mainly used to develop interactive content for the World Wide Web, they can also be used in desktop applications and other programs.
- ActiveX controls
Microsoft
ActiveX™ controls are reusable, stand-alone software components that often expose a subset of the total functionality of a product or application. They were formerly referred to as OLE controls or OCX.
ActiveX controls cannot run stand-alone—they must be loaded into a control container, such as Microsoft Visual Basic or Microsoft Internet Explorer. An ActiveX control can also be embedded in a Visual C++® resource. (See also:
OLE controls)
- ActiveX Data Object (ADO)
ADO is a set of object-based data access interfaces that are optimized for Internet-based, data-centric applications. These interfaces ship with Microsoft Internet Information Server (IIS) and Microsoft Visual InterDev, and enable Web authors to write an application to access and manipulate data in a database server through an OLE DB provider. Primary benefits of using ADOs are high speed, ease of use, low memory overhead, and a small disk footprint.
- ActiveX scripting
ActiveX™ scripting controls the integrated behavior of several ActiveX controls and/or Java applets from the server or the browser. ActiveX scripting is made possible by plugging a scripting engine into a host application. The scripting engine enables the processing of a specific scripting language, such as Visual Basic Scripting Edition or JScript.
- Active stream redirector (ASX) files
ASX files are simply text files that act as a link from a Web page to an ASF file. They transfer control of the data from the HTTP browser to the Windows Media Player so that the data can stream.
- ADO
- Advanced Streaming Format (ASF)
ASF is a low-overhead data format for multimedia streams. It encapsulates images, audio, AVI, and so forth, as well as URLs, and allows for the synchronization of these objects within the stream. Windows Media Technologies can stream ASF formatted content and can store ASF streams as .asf files.
- Application Foundation Classes (AFC)
- ASF
- ASP technology
- ASP component
ASP components are simply components written using ASP, designed to run on a Web server as part of a Web-based application. These components provide key functionality needed for Web applications, such as database access, so that developers do not have to create and re-create the code to perform these tasks. ASP components do not require browser scripting ability, so they are useful for implementing tasks that are difficult with browser scripting.
- ASP session
An
ASP session is an object that utilizes ASP technology to share information about a user between Web pages. As the user navigates between the pages of a site, the state of the user is maintained through a
cookie.
- ASX file
- Asynchronous moniker
An asynchronous moniker is a moniker class that allows the downloading or binding of objects at differing times, without blocking.
- ATL
- Authenticode
Authenticode technology provides a safeguard for downloadable software from the Internet. Serving as a sort of "virtual shrink-wrap" alerting users if the software has been tampered with, Authenticode provides author verification of downloadable software via certificates. If a piece of software has been signed by a publisher, Microsoft Internet Explorer 4.0 can verify that the software originated from the named software publisher and ensure it has not been tampered with. The user can then decide whether to install and run the software, which can include Java applets, ActiveX controls, and plug-ins. If the software has been tampered with since it was published, the user will receive a warning. If the software has not been digitally signed, Internet Explorer 4.0 will ask whether the user wants to download unsigned software.
