need help with barcode

[tquereshi22]

Hi i am having problems with understanding how the barcode process works. I downloaded the IDAutomation components for windows form and have created custom barcodes and printing them using the online tutorial. I am trying to develop a point of sale system and this is the one of the major thing i am stuck, first of all can anyone provide me some code on how to bind data to a barcode, i have a database table call "INVENTORY". And also how do i capture the input frm the scanner and make the bind data shown on the listview box each time a barcode is scanned.

Please its urgent hope some1 can help.

And also how do i capture the input frm the scanner...

Most scanners are keyboard stuffers. When you scan a barcode, the scanner interprets it and puts the characters into the keyboard buffer just as if a human had typed them really, really fast.

If the barcode reader is using a keyboard wedge then, we can force the form focus to an editable control, such as a TextBox and then you use the TextBox's TextChanged event to tell when the scanner enters a new scanned code. If The Barcode reader is using a serial interface, then we can just monitor the serial port for the packet data coming from the device.
