    read barcode one character at

    Henser Villar

      Good evening, I'm reading a bar code in PDF417 format, is an identity, but apparently contains null characters, it is possible to read the bar code character by character to ignore nulls?

      I'm programming in visual studio 2008 vb.net, if you can share the code would be very grateful.

      thank you very much

          Can I suggest you look a the 123Scan utility and use that to program the barcode scanner via the Modify Data / Advanced Data Formatting feature.  This has useful features that allow you to do things such as -


          - search for specific character - eg. null.

          - transmit partial strings - eg. single character or all characters up until the null.


          I hope this helps.
