This part is the form implementation:

          {
              try  //for integer
              {
                  int iCardVal = int.Parse(txtCard.Text.ToString().Trim());

                  if (iCardVal > 0 && iCardVal <= 13)
                  {
                      SimpleCard myCard = new SimpleCard(iCardVal);
                      MessageBox.Show("Card is " + myCard.getInfo());
                  }
                  else
                      MessageBox.Show("Card does not exist");

              }
              catch   //for string
              {

              }

          }
          else
          {
              MessageBox.Show("Enter a value");
              txtCard.Focus();
          }
      }

      private void btnDisplayAllCards_Click(object sender, EventArgs e)
