Barcodes are created and used in Visual Basic 6 through the BFD COM Engine. Though demonstrated here for VB6, COM API can also be easily used in other projects, such as Word Mail Merge and Visual Studio.
Due to well established interfacing guidelines it can be used with many other languages, like C++, Delphi, Java, etc.
