Auto Event Fire

[mudasirahmed]

Hi Guys :
I am working on a Application to read barcodes from a scanner and list
them in a ListBox on a ASP web page. I was wondering if any one has done a
similar job. Is this possible ?

Currently I have attached the scanner to my PC and as I scan a barcode
it reads and puts it on a notepad or textbox. Its a Keyboard wedge type not serial port type connection.
But I need to have control over the barcode and put it in the listbox.
In other words I want to perform some validation before putting into the
list box.
Secondly under what event can I capture the value in the texbox on the
webpage ? The textChange event does not fire untill the user interacts or loses it focus to other object.
So how do i know the end of scan and capture the data ? Or is there a way we can get the data directly before displaying on the page.

The user must not tab or click on the page. He wil just keep scanning
barcodes on after the other on the page. Peep Peep Peep.

Any ideas or code will be really appreciated.

Thanks
