Remarks
When LoadChangeData is called, the provider must take one of the following actions:
- Return a success code from the method and later call IDataRetrieverCallback::LoadChangeDataComplete to report that asynchronous processing finished successfully.
- Return a success code from the method and later call IDataRetrieverCallback::LoadChangeDataError to report that an error occurred during asynchronous processing.
- Return an error code from the method. In this case, IDataRetrieverCallback methods should not be called.
