IOleContainer
The IOleContainer
interface is used to enumerate objects in a compound document or lock a
container in the running state. Container and object applications both
implement this interface.
When to Implement
Applications
that support links and links to embedded objects implement this interface to
provide object enumeration, name parsing, and silent updates of link sources.
Simple, nonlinking containers do not need to implement IOleContainer if
it is useful mainly to support links to embedded objects.
When to Use
Call IOleContainer
to enumerate the objects in a compound document or to lock a container so that
silent updates of link sources can be carried out safely.
Many
applications inherit the functions of IOleContainer by implementing IOleItemContainer, which is used to bind
item monikers.
