>no worries Cetin, I just tried your way and it worked perfectly, thanks a lot, if you can recommend a good book ( or web site ) on using ADO with C#, I'll buy it to save bugging you people

Pete,
I'm the worst source to recommend books:( I don't have much access to books. About ADO.Net I only have one and I'd recommend NOT to buy it, so I think it's not fair to give author's name.
PS: I don't mind about questions as far as I can answer:)
