I think We cant find the number of rows in datareader unless it finishes its read() operation. AS its a Forward only cursor i d rather use a Dataset or try to use a counter for increment after the Read operation..(i guess this may not work).....

' update the label
currRow += 1
Label1.Text = String.Format("{0}% complete", currRow * 100 \ totalRows)
