To receive StringCollectionChange events, you must obtain your string collection as follows:

Call IWMPLibrary::get_mediaCollection to get an IWMPMediaCollection interface.
Call the getAttributeStringCollection method of the interface you obtained in step 1.

If you obtain your IWMPMediaCollection interface by calling IWMPCore::get_mediaCollection, you will not receive StringCollectionChange events.

You can also handle this event through an IDispatch event sink by using the _WMPOCXEvents interface.
