Font Source Code, Header Files & Modules
This source code resource page contains important source code, header files
and modules to help generate readable barcodes from fonts in Visual Basic, 4D,
FoxPro, ANSI C, C++, PowerBuilder, Oracle, LotusScript and Java. The source code, header files and modules
are available here to help IDAutomation barcode font users to more easily format the start
and stop characters,
data strings and checksum characters for demo or purchased barcode fonts.
All IDAutomation source code is copyrighted and
can be incorporated into an application with the purchase of a valid Multi-user or
Developer License. IDAutomation.com, Inc. is owned for the associated
barcode font and the copyright notices are not removed from the source
code. Distributing IDAutomation source code or fonts outside of a
company or organization requires a Developer License. If
IDAutomation barcode font source code is created that might be shared with others,
please
contact IDAutomation.
In some cases, a discount may be provided for IDAutomation's products
if a working source code is provided that would be beneficial to others.
Barcode Font Source Code Index
Note: When selecting the barcode font from the pull down menu,
please do not use the fonts that begin with the
"@" Symbol.
Instead, scroll down the list and select those beginning with
"IDAutomation".
Visual Basic & VB.NET Barcode Font Module
Download the Visual Basic Barcode Font Encoder Module for VB 6 and VB.NET to
calculate a barcode's start, stop and
check digits and return a special string of characters that will generate a
readable barcode when the appropriate IDAutomation font is applied to it.
This method requires nothing to distribute with the application
except the barcode font because the functions of the module are compiled
into IDAutomation's EXE file. The module is free to use with the purchase of
any IDAutomation barcode
fonts. Also review the
Visual Basic Barcode Integration Guide for instruction about how to use the
module.
Support for Universal
barcode
fonts or DataBar
fonts is provided in a VB & VBA module in their respective
packages.
ANSI C & C++ Barcode Source Code
IDAutomation has source code and header files available in ANSI C
for Code 39, Code 39 Mod 43, Codabar, UPC-A, UPC-E, EAN-8, EAN-13, Postnet,
Interleaved 2 of 5, Code 128 and MSI. The Code128() function also supports
UCC/EAN-128. The header file was written to be ANSI C compatible and
has been tested in Visual C++.
Download the C++ header file
that can be added to the application. The text can be formatted for IDAutomation's barcode fonts by adding an include statement such
as #include "IDAutomation.h" to the project and then access the
function this way:
output = Code128b("abc12345");

Oracle Reports & PL/SQL Barcode Library
IDAutomation has a compiled
Barcode Library
for Oracle Reports which is a PLL file that formats
data from fields in the report to IDAutomation's barcode fonts to create
a correct barcode. PL/SQL source code is also provided for advanced Oracle
programmers in the downloaded
IDAutomation.pkg
file.
This source code is an example
of PL/SQL code used in Oracle Reports 3.0 to create the proper string
for the Interleaved 2 of 5 barcode font. Also see IDAutomation's write
up about
installing barcode fonts for Oracle Reports on UNIX.
FoxPro & Visual FoxPro Barcode Source Code
The Visual FoxPro Barcode Source
Code includes most of the barcode functions listed at the bottom
of this page. Add this file as a program module to the VFP project,
set it as a procedure file using SET PROCEDURE TO .. ADDITIVE command
somewhere in the main (startup) code of the project and access the function
in the application as necessary. IDAutomation has demonstrated how this
works in the
Visual FoxPro Sample Project.
The PowerBuilder barcode source code
is used to create the proper string for the Code 128 Barcode Font.
IDAutomation's Visual Basic source code can be used in Lotus
applications as LotusScript such as Lotus Smart Suite, Lotus Approach
and Lotus Notes. The VB source code listed here can also be used for
MS Office as VBA code (also called VB Script) to create macros in Visual Basic.
IDAutomation writes Visual Basic barcode source code
using as few functions as possible to allow for easy conversion to other
programming languages. If source code is created in another language
and may be shared with others, please
contact IDAutomation.
Discounts may be provided for IDAutomation's products, in some cases,
if working source code is provided that would be beneficial to others. View or
download the
Visual Basic
barcode source code only, as the module is not included here.
The following table is a list of common Visual Basic functions used
in IDAutomation's source code and what they do:
| VB Function |
Function Description |
| Asc(character) |
Converts a character to the
ASCII value |
| Chr(n) |
Returns the character represented
by the number n in ASCII |
| Len(string) |
Returns the length of a string |
| Mid(string, x, n) |
Returns n number characters
from a string starting from location x |
| (number Mod n) |
Returns the remainder after number
is divided by n |
| Right$(string, n) |
Returns n characters starting
from the right of the string |
| RTrim(LTrim(string)) |
Removes spaces before and after a
string |
For all functions listed below, the data input type is a single string. A
number may be required for additional parameters. For example,
Code128c("123456",0).
For all number symbologies such as Postnet and UPC, dashes or spaces
may be entered for easier readability which will be filtered out by
the function before the barcode is generated. For UPC-A, UPC-E & EAN-13
enter the +2 and +5 add-on codes by just adding them to the end of the
string.
| Function |
Additional Notes and
Information |
| Code128(Data,
Number) |
Use this Code 128 set if unsure
as to which set should be used for the application. This is a Code 128 Auto function that will automatically
encode any data from ASCII 0 to ASCII 127, and will also
switch to character set C automatically for numbers.
To encode alpha-numeric UCC/EAN-128, ASCII 202 or
character Ê is entered as the FNC1 before each AI. For example,
the UCC number of (8100)712345(21)12WH5678 should be entered
as: Ê8100712345Ê2112WH5678.

AI's and UCC/EAN-128.
(Data, 0) formats barcode output string for
Code 128
barcode fonts.
(Data, 1) returns the human readable data.
(Data, 2) returns only the check digit. |
| Code128a() |
Use the characters
from set B to print characters not on the keyboard; the
scanner will scan characters from set A. Formats output
to the Code 128 barcode fonts. |
| Code128b() |
Returns codes formatted
to the Code 128 character set B. Formats output to the Code
128 barcode fonts. |

digit included.
(Data, 2) returns only the check digit. |
| I2of5() |
This function "interleaves"
numbers into pairs for high density without check digits
and formats the return string to the
Interleaved 2 of 5
fonts. |
| I2of5Mod10(Data,
Number) |
(Data, 0) performs
the mod10 checksum calculation for increased accuracy and
formats the return string to the Interleaved 2 of 5 fonts.

| Code39() |
Formats the output
to print using Code 39
barcode fonts. |
| Code39Mod43(Data,

Code 128 Auto to encode additional FNC1 codes or data containing text or odd
numbers. Use the UCC128 function only for UCC-128 applications where the input
data is an even number such as in SSCC-18 and SCC-14 barcodes. For example, to

input. |
| SCC14(Data, Number) |
SCC14(Data, 0) generates
the MOD10 required and then formats the output to print
EAN-14 and SCC-14 using Code 128 fonts. The input for Data must be a 13 to 17 digit number; however, only
13 are needed. The required application identifier of (01)
is automatically added.
SCC14(Data, 1) returns the human readable data for SCC14
/ EAN14.
SCC14(Data, 2) returns the MOD10 check digit. |
| SSCC18(Data, Number) |
SCC18(Data, 0) generates
the MOD10 required for SSCC-18 and then formats the output

special services numbers with Code 128 fonts. Enter a 19
or 20 digit number; only the first 19 are used.
(Data, 0) formats output to the Code 128 barcode fonts.
(Data, 1) returns the human readable data with the check
digit included.
(Data, 2) returns only the check digit. |

print the UPC-E barcode from a UPC-A barcode that can be
compressed. It will print a UPC-A if it cannot be compressed
by zero suppression rules. Formats output to the UPC/EAN
barcode font. |
