Hi all,

how do you store it in database ? I think you store it in onchange event of textbox right ? and are you using web application or windows application ?

1 solution

Barcode scanners I have used in the past put a carriage return + newline (i.e. "\r\n") at the end of the text so I use the KeyDown event and check for the Enter key to wait for the full barcode to be submitted:

private void tbEnterSerialNum_KeyDown(object sender, KeyEventArgs e)
    if (e.KeyCode == Keys.Enter)
        string serialnumber = this.tbEnterSerialNum.Text;

        // now do enter it into the database...
