To have Code 128 barcode in report from CR you have 2 options:
- Create or use a UFL class library - nice but you need to install additional files into CR runtime directory, and the code 128 font.
- Use a font file and function that returns code 128 formatted string, that you can display it in text object with set font to Code 128. Much simpler, only need to instal Code128 font which is done by very simply in Win7/Win10 already (just open file and click install in font preview dialog).
I decided to go with option 2 which is much easier to implement (still re-writing code that works in CR was PITA ๐ ).
I have rewritten code from page: https://grandzebu.net/informatique/codbar-en/code128.htm#Version which is a gold mine for barcode symbologies information.
Download from mentioned page the font file ( look for paragraph: The font " code128.ttf " ). Open the downloaded font file, make sure that in window you have Version: 2.0
and then click Install in window.
(I am including the font file Code128.ttf v.2.0
in case Grandzebu webpage would gone offline).
In Crystal Reports Formula Workshop, create new Custom function name it MyBarcode128
. Switch syntax to Basic syntax
and paste into window content of the text file: MyBarcode128.txt .
Click Save and close
- if displays an error - I can't help much, I have it working in CR 2019 (in VS extension).
Place a text object (unbound string field), open it's properties (Format object
).
Set Font to Code128, set the font size (I think size about 18-32pt should result in big enough barcode but not too big for most printers).
Edit formula of the object.
You will see Formula Workshop window.
Switch to Crystal syntax (I don't know why it won't work in Basic syntax ๐ค ).
Just type function name MyBarcode128("THE-CODE-CONTENT-")
, or drag into the parenthesis field from Fields.
Now just Save and close
and you can enjoy barcodes in Code 128 on your report.

If you stumble upon squares in your code ( ) then you need to use
common encoding font
(I'm not going into depths about it and what it means - I'm just not interested in it - as long as works ๐ ), just use simchev code, avaiable at his repo: https://github.com/simchev/crystalreports-code128 .
All the most important work came from Grandzebu https://grandzebu.net/. If you find it usefull give him a small donation for his work (you can find link to it at end of page with code description). As for me, I'll be fine if you keep link to my repo in function comment ๐
