Re: Samplclnt example in MDAC 2.8: My Story

I was interested in exploring OLE DB's capabilities as a data consumer
technology, but from everything I'm hearing, it's best served as a mechanism
for exposing data sources (e.g. writing your own provider for .CSV files).
The message is, leave data reading to ODBC; it's a mature technology, but
sometimes newer isn't necessarily better!
