IOleObject::Update method (oleidl.h)
Updates an object handler's or link object's data or view caches.
This method returns S_OK on success. Other possible return values include the following.
||The operation failed.|
||Cannot run object to get updated data. The object is for some reason unavailable to the caller.|
||No caches were updated.|
||Some caches were not updated.|
The Update method provides a way for containers to keep data updated in their linked and embedded objects. A link object can become out-of-date if the link source has been updated. An embedded object that contains links to other objects can also become out of date. An embedded object that does not contain links cannot become out of date because its data is not linked to another source.
When a container calls an embedded object's IOleObject::Update method, it is requesting the object to update all link objects it may contain. In response, the object handler recursively calls IOleObject::Update for each of its own linked objects, running each one as needed.
