Note 1: "Not implemented in COM" means that the code compiles but returns a "not implemented" run-time error.

Note 2: The LotusScript NotesDatabase methods Create, Open with parameters, OpenByReplicaID, OpenIfModified, and OpenMail are implemented in COM in NotesDbDirectory as CreateDatabase, OpenDatabase, OpenDatabaseByReplicaID, OpenDatabaseIfModified, and OpenMailDatabase.

Note 3: You can query and set this property, but it is not actually used.

Note 4: NotesXMLProcessor is not implemented in COM. NotesDXLExporter and NotesDXLImporter implement ExitOnFirstFatalError, Log, and LogComment, rather than inheriting them. NotesDXLExporter initiates processing with the COM-only Export method. NotesDXLImporter initiates processing with the COM-only Import method. Process, SetInput, and SetOutput do not exist in COM.
