Bar code can be an extremely easy task to handle or a more complex one.
Simple barcode methodologies involve nothing more than using a unique font to print the barcode 'characters'.
Other, more complex, barcode methodologies such as supporting retail requirements involve a much more comprehensive approach.
I'll assume for now that you only need a simplistic approach.
There are a variety of barcode fonts available on the web. Some are free and others cost something.
The most commonly used simplistic barcode font is Code 3 of 9 (also known as Code39). Using that barcode symbology can be as simple as installing the font onto the user's workstation and telling the FP Report Form to use that font where needed.
If you need a more comprehensive approach, come back with more details.
Good Luck,
