Transactions and TableAdapters on Win98

Hi,

I am using VS2005 Pro and SQL2005 Express.
I have two tables that I want to update under the same transaction. I don't
understand how to do this using TableAdapters. MSDN says to use
System.Transaction, but it reports that this works only on Win2000 and above
(by the way, do System.Transaction classes work on XP Home ?).
Is there another way so I can maintain compatibility with Win98 ?

Thanks,
Tom.
