I've compiled the source code from the above post and printed the sheet although the scanner I have will not scan the code.

Has anyone been able to produce barcodes with DDOC?

I never tried that example, but I wrote some code for EAN8/13 barcode. (A superset of UPC barcode.)
Should be easy to modify... See: http://www.powerbasic.com/support/pb...hlight=barcode

Bar codes are troublesome on printers other than real bar code printers. We had to try several printers and use the printer's own control language to get it to work reliably.

Hi,

I wrote a barcode EAN13 for Xbase++ (my main development system). The trick was not to use lines, you never know the thickness. Use filled boxes instead.
It works from 40% to 200% (maybe more ...).

Laserprinters normaly works fine, but with inkjets the barcode depends on size (better >80%) and paperquality.

I do not know how this PB code works.

I have uses 3 of 9 with DDOC and have had no problems. Make sure you have the barcode font installed in Windows.....other than that, just tell DDoc the name of the font to use.
There are a number of free 3 of 9 fonts floating around the web. If you need that format and have no luck finding it, send me a PM or email and I will send what I have.

If I attached the jpeg properly, here is a sample screen shot taken from DDoc displaying 3 of 9 barcodes.
