Known Issues

The following section contains known issues that have been identified in Microsoft Active Accessibility 2.0. These issues are current as of July 2001. For updated information, please see the Accessibility home page on MSDN.

Unsupported IAccPropServices Methods

The IAccPropServices interface contains several methods designed for annotating menus that are not currently implemented. For this reason, the following methods are not currently documented in the platform SDK:

• SetHmenuProp
• SetHmenuPropStr
• ClearHmenuProps
• SetHmenuPropServer
• DecomposeHmenuIdentityString
• ComposeHmenuIdentityString

Another approach exists for developers who are interested in customizing the information exposed through Active Accessibility. For more information about annotating menus, see the following two articles on MSDN:

• Microsoft Active Accessibility Architecture (Part 1)
• Microsoft Active Accessibility Architecture (Part 2)

Operating Systems Currently Not Supported by Active Accessibility 2.0

Active Accessibility 2.0 does not currently support Microsoft Windows 95.

Operating Systems Supported by the Active Accessibility 2.0 Redistribution Kit

The Active Accessibility 2.0 RDK supports Microsoft Windows NT 4 Service Pack 6, Microsoft Windows 98, Microsoft Windows 2000, and Microsoft Windows Me. If you upgrade your operating system or apply a service pack, you must reinstall the RDK.

If you want to repair or remove Active Accessibility 2.0, from Control Panel, double-click Add/Remove Programs, select Microsoft Active Accessibility 2.0, and then click Change/Remove. Note that this method completely removes Active Accessibility and does not revert to a previous version.

Text Services Supported by RichEdit 3.0 Only

The Active Accessibility 2.0 Text Services APIs are supported only by RichEdit 3.0, which ships with Microsoft Office XP.

Active Accessibility 2.0 Tools Currently Not Available for 64-Bit Operating Systems

Currently 64-bit versions of the Inspect Object, Accessible Event Watcher, and Accessible Explorer tools do not exist for the IA64 version of Windows XP. You should use the 32-bit version of these tools on this operating system.

Clients Using Word XP Implementation of ITextStore Must Be Rebooted

For Text Services to work properly with Microsoft Word XP, you must restart your system after installing Active Accessibility 2.0.

IAccPropServices::SetPropServer Does Not Manage the Callback Server Properly When Invalid Parameters Are Used

In Active Accessibility 2.0, the IAccPropServices::SetPropserver method increments the reference count and does not release the callback server when invalid parameters are used.

Oleacc Caret Location Inaccurate on Systems without Right-to-Left Support Enabled

The x coordinate for the caret proxy is inaccurate by three pixels. Use the rcCaret value returned by the GetGUIThreadInf function to determine the correct location of the caret.
