The IAccessible::put_accValue method sets the value of the specified object. Not all objects have a value.
Type: VARIANT
Specifies whether the value information being set belongs to the object or one of the object's child elements. This parameter is either CHILDID_SELF (to set information on the object) or a child ID (to set information about the object's child element). For more information about initializing the VARIANT structure, see How Child IDs Are Used in Parameters.
Type: BSTR
A localized string that contains the object's value.
Type: HRESULT
If successful, returns S_OK.
If not successful, returns one of the values in the table that follows, or another standard COM error code. Servers return these values, but clients must always check output parameters to ensure that they contain valid values. For more information, see Checking IAccessible Return Values.
