Servers use ClearProps to restore default values to properties of accessible elements that they had previously annotated.
If servers know the HWND of the object they want to clear, they can use IAccPropServices::ClearHwndProps.
Type: const BYTE*
Identify the accessible element that is to be un-annotated.
Type: DWORD
Length of pIDString.
Type: const MSAAPROPID*
Specify an array of properties that is to be reset. These properties will revert to the default behavior they displayed before they were annotated.
Type: int
Size of paProps array.
Type: HRESULT
If successful, returns S_OK, even if the specified properties were never annotated on the accessible object; clearing already cleared properties is considered a success.
Returns E_INVALIDARG if any of the properties in the paProps array are not supported.
May return other error codes under exceptional error conditions such as low memory.
See the support section for a list of supported properties and their expected types.
Clearing the annotation for a property will cause any associated resources to be released. If a callback property server was used (see SetPropServer), it will be released.
