Help Regarding Not displaying tag ID in a textbox

Question

Hi,

i have build a Project where Employee Swipes their RFID card and its saved in to database.
i Have a textbox name txtSwipe in which Employees TAG id is getting displayed and other processes like Progressbar and different type of messages all are attached with that txtSwipe. i have written code on Mouse CLick Event of txtSwipe.

now when Employee Swipes his/her card i dont want that Tag ID to be displayed to the USER also ON this click event only data is getting properly saved into database if i post code in text changed event or any other data is not getting saved properly.

code i am using is here :

 

<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;

}
