I installed Microsoft SQL Server 2000 Driver for JDBC
I believe the problem is with locating the driver, unlike Java, J# doesn't
use classpath enviromental variable. I am not sure how to add the driver
reference in J#.Hi
Why use JDBC when ADO.NET can do everything for you?

ago.
Sadly, I have to use JDBC.
Can you help?
Thanks

I would much rather use ADO.NET but I can't, I have to use JDBC.
