Barcode types supported

The types of barcodes supported by this release of dBarcode Active DLL are listed in the Barcode Types table in the API Reference section, and details of the barcodes are in the Barcodes Help file which can be found in the installation directory. The code# in the table of barcode types represents the CodeType value used in calls to the Active Barcode Control and the code member of the Barcode structure.

Note that not all barcode types support all characters. Telepen provides codes for upper and lower case letters and most printable characters. Only Extended Code 39, Extended Code 93 and the EAN 128 and Code 128 codes provide symbols for the full ASCII character set.

There are many named barcode types which are actually derivatives of major types. To avoid the table (and user-programming) becoming excessively complex, both the table and calls to the library report only the generic name.

For example: The JAN coding scheme is a variant of the EAN scheme, using a different country code (the first two digits).

There are several coding schemes (such as DEFCON) which are actually Code 39, and some countries use Code 128 under other names for mail tracking (as in the UK).
