InfoPath 2007 Web-based form reading from Bar Code Scanner

Question

May I know if it is possible to query InfoPath 2007 web-based form via a bar code scanner.

Scenario
I have a bar code scanner and a web-based InfoPath form. The InfoPath form contain one section for query data based on a text field (let's name this text field as 'Query'). So, when the bar code scanner scan the bar code of a piece of paper, it will be enter into the 'Query' text field and the result will appear.

Answer 1

Actually, I found another work around.

I select the text field box and use the bar code scanner to scan the bar code and input the value into the text field box.

Then, I click a button label 'Query' and it will display all the data related to that bar code value.

Answer 2

If the barcode scanner works just by faking keyboard entry of the numbers and then simulating a press of the enter button, then you can simply make sure that the input field has focus when the page loads.

document.getElementById('Query').focus();

Put that bit of javascript at the end of the page content and it should work as you expect.

If it doesn't simulate a press of the enter button, then you should set an event on the textbox's onchange event or something similar (maybe set a timer) and check whether input has been entered into the query field. Once there is data in the field, submit the form.
