I recently incorporate barcode printing and reading using de Cayetano's code. It was quite simple to do and althought not all the codes support by the library was correctly recognise, it was enought for me with the Ean13.
In a few day i'd like to test a OCX control captable to print PDF417 codes (but I don't have a reader for that 2D codes).

Aqui encontrarán la clase barlib con ejemplos y la poca documentación existente (pero suficiente) probada con xHarbour 0.99.60 , funcionando muy bien.
Espero esto ayude.
I agree that Barlib is a wonderful barcode library and I use it since years. But please notice that it has some resource leakages. As an example, in banner.prg che command RELEASE is incorrectly used:
release ofont
release open
instead of
release font ofont
release pen open

I've noticed that with barlib barcodes are not displayed when previewing. Bar codes work well only when creating the print job without PREVIEW.
Can someone confirm this?
Thank you,
Reinaldo.
No, I'm using Barlib and preview without problems.

Mi amigo;
Thank you for your reply. BTW - congrats on the WC.
I went back and checked my code. Indeed I'm not using barlib, I'm using VRDBcode instead.
Has anybody been able to preview barcodes using the VRDBcode class?
Thank you,
Reinaldo.
I could see a preview o the barcode but only when print 'one' barcode on the page.
I have modify also the VRDCODE class o fix a bug when print big size barcodes and add support for circular style barcodes.
If you are interest send me a email to send you a copy.
Santi,
Please upload it to www.hyperupload.com and post here the download url. Thanks 
Using VRDBCODE class if you want to do a preview of a report you must use oPrn:hDcOut instead oPrn:hDc when create the codebars.
Greetings.
Santiago Pérez.
Function PrintBarCode()
Local oPrn
Local oBc6
printer oPrn preview
page
oBC6 := VRDBarcode():New( oPrn:hDcOut , "12345678", 80, 80, 10, 10,2 )
oBC6:lCircular:=.t.
oBC6:ShowBarcode()
endpage
endprint
return nil
Ok, I will implement the banner option also.
Create a 180º barcode could be a problem because I use solid circles to get a good barcode image. The arcs can't be easily fill with a color.
Perhaps a good solution it's to overwrite with a white rectangle the half of the circle to want to hide (top, bottom, left or right). I will do a test.
