Hi,

 

There are a lot of great example programs on Developer Zone for decoding and working with barcodes.  What specifically are you having trouble with on your applications?

 

Thanks!

sorry about late reply...i was trying to do it on my own and I just can't seem to get the barcode portion of my code to decode properly.

can you take a look and see what advice you can give me to fix it?

Hello, 

 

I will look into your code to see if there are any major issues, but I really do recommend taking a look at examples.  At the very least, it's good to learn different ways you can implement.  


Thanks!

Can you tell me what exactly is the error that you're seeing?  What's not working properly? Also, your LLB does not include everything in your code, there are some controls/subVIs missing.


Thanks, 


Meghan
