Deactivates the connection between a linked object and its link source.
Indicates the connection was deactivated.
You typically do not call IOleLink::UnbindSource
directly. When it's necessary to deactivate the connection to the link
source, your container typically calls IOleObject::Close
; the linked object's implementation of these methods calls IOleLink::UnbindSource
. The linked object's IAdviseSink::OnClose
implementation also calls IOleLink::UnbindSource
Notes on Provided Implementation
The linked object's implementation of IOleLink::UnbindSource
does nothing if the link source is not currently bound. If the link source is
calls the link source's IOleObject::Unadvise
implementations to delete the advisory connections to the link source. The IOleLink::UnbindSource
method also calls the compound document's IOleClientSite::LockContainer
implementation to unlock the containing compound document. This undoes the
lock on the container and the advisory connections that were established in IOleLink::BindToSource
releases all the linked object's interface pointers to the link source.
