Comments

If OLEDBSimpleProvider::removeOLEDBSimpleProviderListener specifies an event handler interface different from the one previously registered, code the call to fail with E_FAIL.

To correctly implement a provider built with the OSP Toolkit, the listener must be the OLE DB Simple Provider DLL (Msdaosp.dll).

For multiple OLE DB rowsets over the same data set, your implementation must support multiple listeners; otherwise, only one "active" rowset will be allowed.
