In the 3.2.x release, the UUID was used instead of the IMedium object.</div><div><br></div><div>As the IMedium object already has the DeviceType element, is there a need continue to have that as part of the AttachDevice signature?</div><div><br></div><div>Just wondering ...</div><div><br></div><div><br></div><div>2) The IEvent enhancements</div><div>I am using webservice APIs. From the documentation, the IEvent enhancements for 4.0 appear to provide an excellent way to allow passive interfaces to be aware of changes using
IEventSource::RegisterListener.</div><div><br></div><div>From the documentation, we are told that the passive listener would periodically call IEventSource::GetEvent to determine if there is a pending event notification that must be consumed. It then seems once the client has completed processing the event, the IEventSource::EventProcessed function will be called internally.</div><div><br></div><div>The documentation states IEventListener::HandleEvent could be called in passive mode. The documentation however is unclear on what IEventListner::handleEvent does in passive mode.</div><div><br></div><div>Is this call required even in passive mode?</div><div>Does making this call eventually cause IEvent::SetProcessed function to be called? </div><div>Are there limitations to how quickly the IEventSource::GetEvent function can be called?</div><div><br></div><div>I am essentially trying to determine if it might be possible to
mistakenly receive the same notification more than once ... I am assuming not ... but trying to be sure to determine if I need to code for this scenario.</div><div><br></div><div><br></div><div>Thanks for any feedback you can offer.</div><div><br></div><div><br></div><div>Joe</div><div><br></div><div><br></div><div style="position:fixed"></div>
