Hi,

I have a problem with reading text from USB barcode scanner. I found an article about this in code project itseif. Its working pretty much fine here. But problem is at the client place they are using the USB keyboard. So My code not differenciating the input from keyboard or scanner.Both are identifying as HID devices. I need to read data to a particular text box only from the sacnner.This is very much required for me. please reply me if any suggesstions ..

As a barcode scanner typically provides input as if it came from the keyboard, I don't think there's really anything you can do. The whole point of a USB device is that it integrates, not that it identifies itself. Unless you can identify the device from the EventArgs you're sent in the keypress event, I'd say you are hosed, in C# at least.
