    For i = 0 To ds.Tables(0).Rows.Count - 1

        product_ID = Convert.ToInt32(ds.Tables(0).Rows(i).Item(0))

        Product_Name = ds.Tables(0).Rows(i).Item(1)

        product_Price = Convert.ToDouble(ds.Tables(0).Rows(i).Item(2))

        sql = "insert into Product values(" & product_ID & ",'" & Product_Name & "'," & product_Price & ")"

        command = New OleDbCommand(sql, connection)

        adpter.InsertCommand = command
