Hi,

What I have tried:

<pre> try
            {
                this.Cursor = Cursors.WaitCursor;
                label1.Text = "Working...";

                Application.DoEvents();
                SqlConnection con = new SqlConnection(str);
                con.Open();
                SqlCommand cmd = new SqlCommand("Insert into Datatab(rfid) values (@rfid)", con);
                cmd.Parameters.AddWithValue("@rfid", txtSwipe.Text);
                cmd.ExecuteNonQuery();
                con.Close();
                txtSwipe.ResetText();
                label1.Text = "Done";
            }
            catch (Exception ex)
            {
                label1.Text = "Error";
                MessageBox.Show(ex.Message);
            }
            finally
            {
                this.Cursor = Cursors.Default;
            }

            int i;

            progressBar1.Minimum = 0;
            progressBar1.Maximum = 200;

            for (i = 0; i <= 200; i++)
            {
                progressBar1.Value = i;

            }
