Remarks
Applications use this method to get a snapshot of the current properties of an item. These are subsequently restored by calling IWiaPropertyStorage::SetPropertyStream.
Applications can use the pCompatibilityID parameter to check if a device supports a specific set of property values before attempting to write these values to the device.
When it is finished using the item's property stream, the application must release it.
