Re: FLASH: Flash and barcode scanning

[Cheri Harder]

Hi, Gary:


If I remember correctly (was a good many years ago when I worked with bar

coding) you can program the final field on the bar code label to be an

<enter> key entry (with the labeller software).  I just did an experiment

with Flash, since I was worried about the lack of control of "focus" and tab

order, etc, and the following scenario seems to work:


text field named "barcode" - button to submit entry exists (but needn't be

visible) with the following action code:


On (Key: <Enter>)

      Get URL ("www.theASPpage.asp", vars=POST)

      Set Variable: "barcode" = ""

End On


When user presses <Enter> Flash leaves the focus in the text field for the

next entry.  I am just not certain that the variable will get sent before it

gets cleared, was just using the 'clear variable' part of it for

testing....Also, the user must click within the text field before entering

the number, the first time.  After that, focus remains in the field.
