Code 39 Barcode - ASP.NET
This Symbology is also known as ANSI/AIM
Code 39, ANSI/AIM Code 39, Uniform Symbology Specification Code 39, USS Code
39, USS 39, Code 3/9, Code 3 of 9, USD-3, LOGMARS, Alpha39, Code 39 Extended,
and Code 39 Full ASCII
This Barcode Symbology is supported by the following
Neodynamic products:
Overview
 Code 39, the first alpha-numeric
symbology to be developed, is still widely used-especially in non-retail
environments. It is suitable for encoding general purpose alphanumeric data.
Code 39 is a discrete, variable-length symbology. It is self-checking in that a
single print defect cannot transpose one character into another valid
character. It is the standard barcode used by the United States Department of
Defense, and is also used by the Health Industry Bar Code Council (HIBCC). What kind of data can be encoded by Code 39?
-
The Standard Mode (Default implementation) can encode uppercase letters
(A through Z), digits (0 through 9) and a handful of special characters like
the *, -, $, %, (Space), ., /, and +
-
The Full ASCII Mode or Extended Version can encode all 128 ASCII
characters
The * (asterisk) is not a true encodable character, but is the
start and stop 'symbol' for Code 39.

Note: Please refer to the Class
Reference documentation for more information about the properties and methods
stated in this document.
In order to get a Code 39 barcode image, please follow these
steps:
-
Set the Symbology property to Code39
-
Set the AddChecksum property to False
-
By default, Code 39 can only encode uppercase letters (A through Z), digits (0
through 9) and a handful of special characters like the *, -, $, %, (Space), .,
/, and +. If you need to encode all 128 ASCII characters, please set the Extended
property to True
-
Setting up dimensions and quiet zones:
-
Set the BarWidth and BarHeight properties (Values are expressed
in Inches)
-
Set the QuietZoneWidth property (Value is expressed in Inches)
-
Set the TopMargin and BottomMargin properties (Values are
expressed in Inches)
-
Set the Code property with the value to encode.
-
Code 39 utilizes asterisk characters as Start & Stop symbols and they
are shown in the human readable text of a barcode image. You can rid of those
characters from the human readable text by setting up the DisplayStartStopChar
property to False

Setting up dimensions and quiet zones:
All values for barcode dimensions are expressed
in INCHES by default. However, Barcode Professional supports other unit
of measurement such as Millimeter, Centimeter, and Mils.
For modifying the unit of measurement for barcoding, please set up the BarcodeUnit
property as needed.

Example of Code 39 barcode images
Code property = ABC 123456789 will produce the
following barcode image:
Code property = (abc) 123456789 and Extended
property = True will produce the following barcode image:
