22 * The OLE2 default object handler supports a whole whack of
23 * interfaces including:
24 * IOleObject, IDataObject, IPersistStorage, IViewObject2,
25 * IRunnableObject, IOleCache2, IOleCacheControl and much more.
27 * All the implementation details are taken from: Inside OLE
28 * second edition by Kraig Brockschmidt,
31 * - This implementation of the default handler does not launch the
32 * server in the DoVerb, Update, GetData, GetDataHere and Run
33 * methods. When it is fixed to do so, all the methods will have
34 * to be revisited to allow delegating to the running object
36 * - All methods in the class that use the class ID should be
37 * aware that it is possible for a class to be treated as
38 * another one and go into emulation mode. Nothing has been
41 * - Some functions still return E_NOTIMPL they have to be
42 * implemented. Most of those are related to the running of the
45 * - All the methods related to notification and advise sinks are
46 * in place but no notifications are sent to the sinks yet.
