Printing UPC, ISBN-13, EAN, & JAN barcodes in C/C++
Azalea Software's UPCTools package supports printing barcodes within your C or C++ programs.
Please contact us via email at technicalsupport at azalea dot com for details. Our sincere apologies for not having the code up here already.
Meanwhile we do offer a Visual Basic code that you can customize and incorporate. If you make an C widget with it, please share it with us and not only will we give you credit, we'll send you an Azalea t-shirt.
