The VARIANT index provided specifies either an integer index in the collection or a name which searches the first word following the tag.
Syntax
HRESULT Item(
[in] VARIANT varIndex,
[out, retval] BSTR* retval
);
Function Item(ByVal varIndex) As String
Parameters
varIndex
Specifies either an integer index in the collection or a name.
Remarks
The named lookup is useful in the Params and Exceptions collections because the first word contains the name of the parameter or type of exception, which is subsequently documented.
