I have two sets of barcodes which are being read by a scanner (HID device).

  1. If the barcode scanned is of type A it should be sent to the app on focus
  2. If the barcode scanned is of type B then the barcode should be written to a file and destroyed. It should NOT be sent to the app on focus.

I would like to just "listen" to the HID device but the unhooking is giving me some issues. Is the above even possible?

Please explain what you mean by "unhooking" and how it is giving you trouble. I have a hard time finding something in your question that wouldn't be solved by a simple if instruction in your application. – Oliver Salzburg Apr 23 '12 at 10:56
    
I agree with above comment, and please show your efforts, otherwise it is impossible for anyone to know what your problem might be. – Daniel Andersson Apr 23 '12 at 10:58
