We've got a web-based system that will be printing barcodes into PDF files. What I would love is if there was a free/open source .net component that would accept a text string and hand back a graphic of a bar code. Sure, we could just use a bar-code font, but I'd really rather not compute the checksum myself if I don't have to. Ditto ...
