Capture barcode input in Textbox

[lexavision]

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:

    private void txtTicketID_TextChanged(object sender, EventArgs e)
    {


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


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