Mapping ARIA Roles, States, and Properties to UI Automation
The World Wide Web Consortium (W3C) defines Accessible Rich Internet Applications (ARIA) as a syntax for making dynamic Web content and custom UI accessible. Internet Explorer 8 recognizes the ARIA role, state, and property information and exposes it to assistive technologies, which in turn can use the Microsoft Active Accessibility and/or Microsoft UI Automation APIs to retrieve the information. Instead of building separate simplified Web pages for accessibility, you can use ARIA to mark up your rich Web applications with roles, states, and properties. For example, to match the behavior you create through a script, you can define a div element as a button, checkbox, or another ARIA role.
For many existing and future Microsoft ActiveX controls, Internet Explorer 8 removes administrative involvement from the installation process. The solution addresses issues raised by enterprise customers who used previous versions of Internet Explorer, where administration of controls was not optimal. Non-administrative ActiveX controls (or per-user ActiveX installation) is available on Windows Vista and later.
Internet Explorer 8 allows greater control of where and under what context ActiveX controls can run. In this version of Internet Explorer, ActiveX controls that are embedded as Web objects are presented to the user as add-ons. Through the new Manage Add-ons dialog box, the registry, or site-locking technology (such as the SiteLock ATL Template), these add-ons can be restricted for use on specific Web sites.
Protected Mode Broker Functions
Internet Explorer 8 in Windows Vista provides broker functions that allow access between applications, processes, and resources secured to other integrity levels.
What's New for Accessibility in Internet Explorer 8
Internet Explorer 8 contains several new features that support assistive technology client applications.
Windows 7 Accelerator Platform
The Accelerator Platform is a powerful tool for integrating Web services in Internet Explorer 8, but it's actually surprisingly simple to use from within other applications on Windows 7. This article describes how a developer might access the features of the Accelerator Platform from code with examples in C#.
