Capture barcode input in Textbox

Hi,

I have a USB scanner that I use to input into a textbox. The issue is that I'll need to check for a barcode that is 6 digits long and another that is 9 digits long. Since the characters come in one at a time the 6 char length condition will always be satisfied. Has anyone had to deal with something like this?

Code Samle:

Code:

---

    private void txtTicketID_TextChanged(object sender, EventArgs e)
    {


      if (txtTicketID.Text.Length == 9)
      {
            .....
      }


      if (txtTicketID.Text.Length == 6)
      {
            .....
      }

maybe you can do it like this...

Code:

---


    if (txtTicketID.Text.Length > 8 &&  txtTicketID.Text.Length < 10)
      {
            .....
      }


      if (txtTicketID.Text.Length > 5 && txtTicketID.Text.Length < 7)
      {
            .....
      }

Can't you just read from the scanner until it is done and then update the textbox?

Even Spock couldn't write the logic for that. ;)

As Ed says, you need to read all of the characters from the Barcode reader before processing it. If the reader can read Barcodes that translate to either 6 or 9 or N digits, there must be a termination character included in its output?
