•Volume member is a VDS_VOLUME_NOTIFICATION (section 2.2.1.3.4) with the followingattributes:•ulEvent is VDS_NF_VOLUME_MODIFY.•volumeId is the VDS_OBJECT_ID (section 2.2.1.1.3) of the volume object correspondingto the removable media drive.•plexId SHOULD be GUID_NULL, but it is not relevant when ulEvent isVDS_NF_VOLUME_MODIFY.•ulPercentCompleted needs to be from 0 to 100 and is implementation-specific, but it is notrelevant when ulEvent is VDS_NF_VOLUME_MODIFY.Then, if media was present in the drive, for each callback object that is registered in the list ofcallback objects, the server MUST call the callback object's IVdsAdviseSink::OnNotify() methodby using a VDS_NOTIFICATION structure that has the following attributes:•objectType member is VDS_NTT_DISK.•Disk member is a VDS_DISK_NOTIFICATION (section 2.2.1.3.3) that has the followingattributes:•ulEvent is VDS_NF_DISK_MODIFY.•diskId is the VDS_OBJECT_ID of the disk object corresponding to the removable mediadrive.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011280 / 360
4 Protocol ExamplesThe following sections provide examples of how a Virtual Disk Service Remote Protocol client andserver communicate in common scenarios.A VDS client typically performs these operations in the following order:1. Starts the VDS session.2. Registers for notifications.3. Receives notifications.4. Enumerates the VDS object.5. Retrieves properties of the VDS object.6. Performs tasks.7. Unregisters for notifications.8. Ends the VDS session.4.1 VDS Sessions4.1.1 Starting SessionsThe following is an example of a client starting a VDS session by retrieving an instance of the VDSservice object.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011281 / 360
