Hi, Thanks for your answer. I will test it on 1.1 tomorrow to see. Dan

Hi, Thanks again for your answer. I decompiled the Reset methods and saw that it uses Clear internally. Probably I'll just move to .NET 1.1 and see what happens. The loading of the tables works nice so I do not have to Me.DACompanyContacts.Fill(ds.CompanyContacts) , just using it as I did works fine. Thanks again, Dan
