Two unnamed DBIDs, also called object IDs, can be used to reference object containers. Both of these DBIDs are of the type DBKIND_GUID_PROPID, as are DBCOLUMN* and DBROWCOL*. Use these DBIDs in the SEC_OBJECT_ELEMENT structure to identify object containers.
The following DBID refers to all existing and any new objects created in the container:
{DBGUID_CONTAINEROBJECT, DBKIND_GUID_PROPID, (LPOLESTR) 2}
The following DBID refers only to all new objects created in the container:
{DBGUID_CONTAINEROBJECT, DBKIND_GUID_PROPID, (LPOLESTR) 3}
