Remarks
Notes to Callers
OnInPlaceActivate is called by the active embedded object when it is activated in-place for the first time. The container should note that the object is becoming active.Notes to Implementers
A container that supports linking to embedded objects must properly manage the running of its in-place objects when they are UI-inactive and running in the hidden state. To reactivate the in-place object quickly, a container should not call IOleObject::Close until the container's IOleInPlaceSite::DeactivateAndUndo method is called. To help protect against the object being left in an unstable state if a linking client updates silently, the container should call OleLockRunning to lock the object in the running state. This prevents the hidden in-place object from shutting down before it can be saved in its container.Requirements
