How to insert a row with a column with an auto increase

i have a table with 2 column with this scheme: ID | Name ID = counter primary key Name = text i use this code to add new rows in the table. But for the first item newRow("ID") it is a counter so it auto increase itself. I have no to update. But if i don't i get error. Dim newRow As DataRow newRow = global.ds.Tables(0).NewRow newRow("ID") = ?????? newRow("Nome") = txbNome.Text global.ds.Tables(0).Rows.Add(newRow) global.da.Update(global.ds, "myTable") How can add a new row and leave the system database handle the ID column?
