3.1.4.4.5 IsMergeAppend (Opnum 7)

  • Article

The IsMergeAppend method is received by the server in an RPC_REQUEST packet. In response, the server returns a Boolean that represents whether the IAppHostElementCollection, from which the specified IAppHostCollectionSchema was retrieved, will prepend collection IAppHostElement objects from lower (deeper) in the hierarchy of the administration system with IAppHostElement objects from higher (shallower) in the hierarchy of the administration system.

If the value is false, lower IAppHostElement objects are prepended; otherwise, they are appended.

 [propget] HRESULT IsMergeAppend(
   [out, retval] VARIANT_BOOL* pfIsMergeAppend
 );

pfIsMergeAppend: The Boolean value that represents the append or prepend behavior.

Return Values: The server MUST return zero if it successfully processes the message that is received from the client. 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.
