How to Compare Prefix of barcode ?

Do you mean the user will insert the barcode value (which might be the item number), and you want to find (mark as selected) the related item?

If yes, first you need to get all barcodes values in array of strings. And then when the user inserts the text in the textbox, the program starts searching the text inside the array of strings.
If it finds a match, it returns the item number (or barcode value) and select the related item. More details can be found here:

If you want to recognize the barcodes values, you can do this using a programming toolkit like LEADTOOLS that supports reading different types of barcodes. More details can be found here:
