+ @section _errors Error Handling
+ HRESULT values are defined by the Microsoft&reg; Win32&reg; API. For more information, refer to
+ <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa378137%28v=vs.85%29.aspx">
+ Interpreting HRESULT Values</a> in MSDN&reg;.
+
+ Note that the S_FALSE return value is considered a non-error value and the
+ SUCCEEDED macro will return TRUE. S_FALSE is used when there is no failure
+ but there was nothing valid to return, e.g. in IAccessible2::attributes when
+ there are no attributes. When S_FALSE is returned [out] pointer types should
+ be NULL and [out] longs should generally be 0, but sometimes -1 is used such
+ as IAccessible2::indexInParent, IAccessibleText::caretOffset, and
+ IAccessibleHypertext::hyperlinkIndex.
+
+ Note that for BSTR [out] variables common COM practice is that the server does
+ the SysAllocString and the client does the SysFreeString. Also note that when
+ NULL is returned there is no need for the client to call SysFreeString. Please
+ refer to the documentation for each method for more details regarding error handling.
+
+ @section _memory Memory Management
+ The following memory management issues should be considered:
+ @li Although [out] BSTR variables are declared by the client, their space is
+ allocated by the server. They need to be freed with SysFreeString by the
+ client at end of life; the same is true when BSTRs are used in structs or
+ arrays which are passed to the server.
+ @li If there is no valid [out] BSTR to return, the server should return S_FALSE and
+ assign NULL to the output, e.g. *theOutBSTR = NULL;.
+ @li COM interfaces need to be referenced with AddRef when used and dereferenced
+ with Release at end of life.
+ @li Single [out] longs, HWNDs, booleans, and structs are declared by the caller
+ and passed by reference. The marshaller does all the memory management.
+
+ The following articles may be helpful for understanding memory management issues:
+ @li An article by Don Box in a
+ <a href="http://www.microsoft.com/msj/1196/activex1196.aspx">Q & A section</a>
+ of the November 1996 edition of the Microsoft Systems Journal.
+ @li A posting to a CodeGuru forum,
+ <a href="http://www.codeguru.com/forum/showthread.php?t=364511">Windows SDK
+ String: What are the rules for BSTR allocation and deallocation?</a>
+
+ @subsection _arrayConsideration Special Consideration when using Arrays
+ There are several methods which return arrays. In the case of IAccessible2::relations
+ and IAccessibleRelation::targets the client must allocate and free the arrays.
+
+ For the remaining methods which return arrays, the server must allocate the array
+ and the client must free the array when no longer needed. These methods are
+ IAccessible2::extendedStates, IAccessible2::localizedExtendedStates,
+ IAccessible2_2::relationTargetsOfType, IAccessibleAction::keyBinding,
+ IAccessibleHypertext2::hyperlinks, IAccessibleTable::selectedChildren,
+ IAccessibleTable::selectedColumns, IAccessibleTable::selectedRows,
+ IAccessibleTable2::selectedCells, IAccessibleTable2::selectedColumns,
+ IAccessibleTable2::selectedRows, IAccessibleTableCell::columnHeaderCells,
+ and IAccessibleTableCell::rowHeaderCells.
+ For those methods, the server must allocate both the top level array and any storage
+ associated with it, e.g. for BSTRs. The server must allocate the arrays with
+ CoTaskMemAlloc and any BSTRs with SysAllocString. The client must use CoTaskMemFree
+ to free the array and any BSTRs must be freed with SysFreeString.
+
+ Also, the IDL for IAccessible2::extendedStates, IAccessible2::localizedExtendedStates,
+ IAccessibleAction::keyBinding, IAccessibleTable::selectedChildren,
+ IAccessibleTable::selectedColumns, and IAccessibleTable::selectedRows includes an
+ extraneous [in] parameter for the caller to specify the max size of the array.
+ This parameter will be ignored by the COM server.
+
+ @section _indexes Zero and One Based Indexes
+ Unless otherwise specified all offsets and indexes are 0 based.
+
+ @section _enumBase Enum Base
+ Note that enums start at 0.
+
+ @section _specialOffsets Special Offsets for use in the IAccessibleText and IAccessibleEditableText Methods
+ IAccessibleText and IAccessibleEditableText can use one or more of the following
+ special offset values. They are defined in the ::IA2TextSpecialOffsets enum.
+ @li Using ::IA2_TEXT_OFFSET_LENGTH (-1) as an offset in any of the IAccessibleText or
+ IAccessibleEditableText methods is the same as specifying the length of the string.
+ @li Using ::IA2_TEXT_OFFSET_CARET (-2) as an offset for IAccessibleText::textBeforeOffset,
+ IAccessibleText::textAtOffset, and IAccessibleText::textAfterOffset indicates that the
+ text related to the physical location of the caret should be used. This is needed for
+ applications that consider the character offset of the end of one line (as reached by
+ pressing the End key) the same as the offset of the first character on the next line.
+ Since the same offset is associated with two different lines a special means is needed
+ to fetch text from the line where the caret is physically located.
+
+ @section _dicoveringInterfaces Discovery of Interfaces
+ In general AT (Assistive Technology) should try IAccessible2 interfaces, followed by using
+ the MSAA (Microsoft&reg; Active Accessibility&reg;) interfaces. (In cases where the an application
+ is known to have custom interfaces which provide information not supplied by IAccessible2
+ or MSAA, then those custom interfaces can be used.) The AT can then, by default, support
+ unknown IAccessible2/MSAA applications, without the application developers having to request
+ AT vendors for support on an individual application by application basis.
+
+ When you have a reference to an IAccessible and require a reference to an IAccessible2 use
+ QueryService as follows:
+ @code
+ // pAcc is a reference to the accessible object's IAccessible interface.
+ IServiceProvider *pService = NULL;
+ hr = pAcc->QueryInterface(IID_IServiceProvider, (void **)&pService);
+ if(SUCCEEDED(hr)) {
+ IAccessible2 *pIA2 = NULL;
+ hr = pService->QueryService(IID_IAccessible, IID_IAccessible2, (void**)&pIA2);
+ if (SUCCEEDED(hr) && pIA2) {
+ // The control supports IAccessible2.
+ // pIA2 is the reference to the accessible object's IAccessible2 interface.
+ }
+ }
+ @endcode
+
+ @section _changingInterfaces Changing between Accessible Interfaces
+ Note that developers must always implement MSAA's IAccessible and, if needed, some
+ of the interfaces in the set of IAccessible2 interfaces. Although the IAccessible2
+ IDL is coded such that IAccessible2 is a subclass of MSAA's IAccessible, none of
+ MSAA's IAccessible methods are redefined by IAccessible2.
+
+ QueryService must be used to switch from a reference to an MSAA IAccessible interface
+ to another interface. This has been
+ <a href="http://www.atia.org/files/public/Introducing_IAccessibleEx.doc">
+ documented</a> and the pertinent facts have been extracted below:
+
+ @par
+ Why use QueryService instead of just using QueryInterface to get IAccessibleEx
+ directly? The reason is that since MSAA 2.0, clients don't talk to a server's
+ IAccessible interface directly; instead they talk to an intermediate MSAA-provided
+ wrapper that calls through to the original IAccessible. This wrapper provides services
+ such as implementing IDispatch, supplying information from MSAA 2.0's Dynamic Annotation
+ service, and scaling locations when running on Windows Vista with DPI scaling enabled.
+ QueryService is the supported way to expose additional interfaces from an existing
+ IAccessible and was originally used by MSHTML to expose IHTMLElement objects corresponding
+ to IAccessibles. QueryService is often more convenient for servers to implement than
+ QueryInterface because it does not have the same requirements for preserving object
+ identity or symmetry/transitivity as QueryInterface, so QueryService allows servers to
+ easily implement the interface on the same object or a separate object. The latter is
+ often hard to do with QueryInterface unless the original object supports aggregation.
+
+ Two related references in MSDN&reg; are:
+ @li <a href="http://msdn.microsoft.com/en-us/library/ms696078(VS.85).aspx">
+ "Using QueryService to expose a native object model interface for an IAccessible object"</a>
+ @li <a href="http://msdn.microsoft.com/en-us/library/ms528415.aspx#acc_obj">
+ "Accessing the Internet Explorer Object Associated with an Accessible Object"</a>
+
+ Based on this information from Microsoft, QueryService must be used to switch back and forth
+ between a reference to an MSAA IAccessible interface and any of the IAccessible2 interfaces.
+
+ Regarding switching between any of the IAccessible2 interfaces, applications implementing
+ IAccessible2 should implement the IAccessible2 interfaces on a single object since ATs
+ will be using QueryInterface to switch between the IAccessilbe2 interfaces. Implementing
+ the IAccessible2 interfaces on separate objects would require the use of QueryService.
+ There is one exception, IAccessibleApplication can be implemented on a separate object so
+ its common code doesn't have to be included in each accessible object. ATs should use
+ QueryService to access IAccessibleApplication.
+
+ @section _applicationInfo Access to Information about the Application
+ Servers implementing IAccessible2 should provide access to the IAccessibleApplication
+ interface via QueryService from any object so that ATs can easily determine specific
+ information about the application such as its name or version.
+
+ @section _childIDs Child IDs
+ The IAccessible2 interfaces do not support child IDs, i.e. simple child elements.
+ Full accessible objects must be created for each object that supports IAccessible2.
+ Therefore MSAA's get_accChild should never return a child ID (other than CHILDID_SELF)
+ for an object that implements any of the IAccessible2 interfaces.
+
+ Microsoft's UI Automation specification has the same limitation and this was resolved
+ in the UI Automation Express specification by adding IAccessibleEx::GetObjectForChild
+ and IAccessibleEx::GetIAccessiblePair. These methods allow mapping back and forth
+ between an IAccessibleEx and an {IAccessible, Child ID} pair. A future version of
+ IAccessible2 may include similar methods to map back and forth between an IAccessible2
+ and an {IAccessible, Child ID} pair.
+
+ @section _variants VARIANTs
+ Some methods return a VARIANT. Implementers need to make sure that the return type is
+ specified, i.e. VT_I4, VT_IDISPATCH, etc. The methods that return VARIANTs are
+ IAccessibleHyperlink::anchor, IAccessibleHyperlink::anchorTarget, IAccessibleValue::currentValue,
+ IAccessibleValue::maximumValue, IAccessibleValue::minimumValue.
+
+ @section _iaaction-iahyperlink IAccessibleHyperlink as subclass of IAccessibleAction
+ In this version of the IDL, IAccessibleHyperlink is a subclass of IAccessibleAction.
+ However, there is no practical need for that inheritance and in some cases, such as
+ an image map of smart tags, it doesn't make sense because such an image map doesn't
+ have actionable objects; it's the secondary smart tags that are actionable. As a
+ result, implementations should not rely on the inheritance as it may be removed in
+ a later version of the IDL.
+
+ @section _trademark Trademark Attribution
+ The names of actual companies and products mentioned herein may be the trademarks of
+ their respective owners. In particular, Active Accessibility, Microsoft, MSDN, and Win32

+
+ This value is provided so the AT can have access to a unique runtime persistent
+ identifier even when not handling an event for the object.
+
+ An example of when this value is useful is if the AT wants to build a cache.
+ The AT could cache the uniqueIDs in addition to other data being cached.
+ When an event is fired the AT could map the uniqueID to its internal model.

+/** @brief This interface represents hyperlinks.
+
+ This interface represents a hyperlink associated with a single substring
+ of text or single non-text object. Non-text objects can have either a
+ single link or a collection of links such as when the non-text object is
+ an image map.
+
+ Linked objects and anchors are implementation dependent. This interface is derived
+ from IAccessibleAction. IAccessibleAction::nActions is one greater than the
+ maximum value for the indices used with the methods of this interface.
+
+ Furthermore, the object that implements this interface has to be connected
+ implicitly or explicitly with an object that implements IAccessibleText.
+ IAccessibleHyperlink::startIndex and IAccessibleHyperlink::endIndex are
+ indices with respect to the text exposed by IAccessibleText.
+
+ This interface provides access to a single object which can have multiple actions.
+ An example is an image map which is an image with multiple links each of which is
+ associated with a separate non-overlapping area of the image. This interface could
+ also be applied to other kinds of objects with multiple actions such as "smart tags"
+ which are objects, typically strings, which have multiple actions such as
+ "Activate URI", "Bookmark URI", etc.
+
+ An interesting use case is an image map where each area is associated with multiple
+ actions, e.g. an image map of smart tags. In this case you would have to implement
+ two levels of accessible hyperlinks. The first level hyperlinks would only implement
+ anchor and anchorTarget. The anchors would all reference the image object. The
+ anchorTargets would reference the second level accessible hyperlink objects. None
+ of the IAccessibleAction methods would be implemented on the first level hyperlink
+ objects. The second level hyperlink objects would implement the IAccessibleAction
+ methods. Their anchors would also reference the image object and their anchorTargets
+ would reference URLs or the objects that would be activated.
+
+ This use case demonstrates that in some cases there is no need for IAccessibleHyperlink
+ to derive from IAccessibleAction. As a result it may be removed in a later version of
+ the IDL and it is suggested that implementations should not rely on the inheritance.

+ will be at the same time children of the table. In this case IAccessible2::indexInParent
+ will return the child index which then can be used when calling IAccessibleTable::rowIndex
+ and IAccessibleTable::columnIndex.
+
+ However, in some cases that kind of implementation will not be possible. When
+ the table cells are not direct children of a table, the object representing
+ the cell can define a "table-cell-index" object attribute identifying the 0
+ based table cell index. This object attribute is obtained by parsing the
+ attribute string returned by IAccessible2::attributes. The "table-cell-index"
+ attribute can be used just like a child index of the typical case. ATs should
+ first test for the presence of the "table-cell-index" attribute and if it is not
+ present then IAccessible2::indexInParent can be used as in the typical case
+ where cells are direct children of the table.
+
+ The range of valid coordinates for this interface are implementation dependent.
+ However, that range includes at least the intervals from the from the first row
+ or column with the index 0 up to the last (but not including) used row or column
+ as returned by IAccessibleTable::nRows and IAccessibleTable::nColumns.
