>Galaksi.Yeni.OrderSystem.OrderDetailDataAccessSql.CreateDataAccessObject(string)': no suitable method found to override

>first, i'm looking for this method by VS.NET object browser, this method must be the member base class "mmDataAccessSql" but I haven't seen it.

Actually, the CreateDataAccessObject method isn't on the data access object...it's on the business object (the business object is responsible for creating the data access object). That's why you were getting the error "no suitable method found to override".
