          dataConnection.Open();
          MySqlTransaction transakcija = dataConnection.BeginTransaction();
          MySqlCommand dataCommand = new MySqlCommand();
          dataCommand.Connection = dataConnection;
          dataCommand.Transaction = transakcija;
          try
          {
              dataCommand.CommandText = "Insert INTO login.users (ime,upIme,geslo,dovoljenja) VALUES ('" + this.tB_Ime.Text + "','" + this.tB_upIme.Text + "','" + this.tB_geslo.Text + "', 'Navaden uporabnik')";
              dataCommand.CommandType = CommandType.Text;
              dataCommand.ExecuteNonQuery();
              transakcija.Commit();
              MessageBox.Show("Registracija uspešna!");

              MessageBox.Show("Napaka pri registraciji\n" + eks.Message);
          }
          finally
          {
