Code Samples

Note:   The samples below contain a demo of only the Code 39 DLL. If you would like to use any of the other bar code symbologies you will need to purchase the commercial release of the DLLs. The B-Coder Demo is easier to use if you are only interested in demonstrating the quality of the bar codes created by the DLLs. B-Coder is an application program that uses the same bar code graphic generation code as the DLLs.
