The new control created by you is called Extended Control, and .NET Codabar Generator Control is the base control of the extended Control.

Codabar Background informationCodabar is a barcode symbology which is linear. It was invented in 1972 by Pitney Bowes Corp. Codabar also has other well-known names such as Code 2 of 7, Ames Code, Codeabar, Monarch, NW-7, Rationalized Codabar, ANSI/AIM BC3-1995 and USD-4. Till now, Codabar has not officially been signed up for American trademark status, yet Code-a-bar which is its variant is a widely recognized trademark.
Codabar HistoryOriginally, it was designed to be read precisely even when printed on dot-matrix printers for various forms that have blood bank and FedEx airbills forms. There is even a possibility of printing Codabar codes by using impact printers, which are typewriters-like. Despite the fact that newly updated symbologies include more information in a fairly smaller space, Codabar has a huge installed base in libraries. Besides, it can help create plenty of codes with subsequent numbers, in which process no digital equipment has to be used. For instance, in mechanical mile counters, the printer's stamp is automatically moved on to the next number when each code is done being printed.
Codabar EncodingThat the body of a Codabar string may only encode the numerals 0 through 9 depends on the special criterion. The symbols such as dollar, dash, plus sign, colon, slash, and dot are also allowed by some variants. As Codabar is self-checking, a check digit is not defined by most standards. Nevertheless, a particular check digit is required by the variants of Codabar when they are used in public and in commercials.
Codabar SpecificationsIn many specifications, some alphabet characters like A, M, N, T, are usually used in matching pairs so that they can represent the beginning and the end of the barcode. However, this phenomenon can never be seen in the body of a Codabar string.
