Dear NI supporter,

                         I am using labview 7.1. For one of my project I am using barcode with USB port(barcode make SYMBOL N1KEAR) I tryed with VISA USB control but not reading the barcode value. So kindly send me the example program for the same.

Regards

USB barcode scanners emulate a keyboard. All you need is a string control. It's the same thing as typing.

Dear Sir

           I already used RS232 port to communicate the barcode. For that I used RS232 read VI which is in tool bar like that I want to know without placing the cursor on the string control first I want to read the barcode scanned value and then I want to compare the same is valid or not then only I want to display it in the front screen.
