The Item method is received by the server in an RPC_REQUEST packet. In response, the server returns the property that is specified by the specific index.
-
[propget, id(DISPID_VALUE)] HRESULT Item( [in] VARIANT cIndex, [out, retval] IAppHostProperty** ppProperty );
cIndex: The VARIANT index of the property to be fetched. If the VARIANT is of type integer, the index is a zero-based index to the collection. If the VARIANT is of type string, the index is a string that is the name of the property being retrieved.
ppProperty: Contains the retrieved property.
Return Values: The server MUST return zero if it successfully processes the message that is received from the client. In this case, *ppProperty is not NULL. If processing fails, the server MUST return a nonzero HRESULT code as defined in [MS-ERREF]. The following table describes the error conditions that MUST be handled and the corresponding error codes. A server MAY return additional implementation-specific error codes.
