Changes to AdvDsDataSourceInfo project
The OPC Data Source Definition aspect (CAdvDsOpcDataSource) had an interface method IAdvDsOpcDataSource::ServerName() I was using. Without altering the interface, this property was obsoleted (now returns and empty string). The replacement interface IAdvDsOpcDataSource2 has a replacement method ServerRemoteNodeName(). Unfortunately, the coclass wasn't updated to expose the replacement interface, so it is not accessible without doing a QueryInterface(), which I understand we're not supposed to use.
