[RESOLVED] pdf417 barcode

[Davor Geci]

Hello guys,
does anyone have a free solution how to generate pdf417 barcodes in a picturebox or in a label?

For days now I'm traying with this code:
https://github.com/fwahyui/VB6/tree/master/BARCODE

It generates the pdf417 barcode, but when I want to scan it (on my screen or on printed document) the scanner just doesn't want to recognize it.
Does anyone here have some other method that I could try?

Thanks,
Davor

Have you tried to scan other PDF417 barcodes with the scanner to insure it will scan them?
I have some stuff here that prints PDF417 but sadly neither were freely available to the general public, the best one came from Symbol and was a free download but only for developers registered with them, they have since been bought out and the policies have changed. I have no idea if the files are even available anymore.

The required files from symbol are
PDF32.Bas PDFENC32.DLL
It's been over 20 years since I downloaded them so have no idea if they were a separate download or if they were part of a symbol developers kit. I downloaded many of those over the years as I did a lot of development for symbol devices.

Thanks DataMiser for your response.
Yes, I did test with other PDF417 barcodes and it works.
Not sure what it is. The barcodes look almost the same, but the scanner can't recognize this mine.
Hm.

Thank you all guys.

I have found the solution or where the problem was.

Now it works :-)

On all the places where you can download this code it is an older version of the code. But on the authors homepage there is a newer version.
We can see it by the version number that the author has put in the code.

The main function is:

Private Function pdf417$(Chaine$, Optional ByRef sécu%, Optional ByRef nbcol%, Optional ByRef CodeErr%)

and there is a line with the version. In my case it was 'V 1.2.0

But after downloading the code from the authors homepage, this function is having version number 'V 1.5.0

There are a lot's of code lines changed between this 2 version, and I don't speak Franch so I'm not sure what was the problem (all the comments are on french)

If anyone will have the same problem or will be in need for PDF417 barcodes in VB6 or VBA here is that authors homepage and the latest code:

Once again thank you all for your help and posts.

I have no idea though I doubt they were ever in that format, likely a zip or msi file and may have been part of one of the many development kits issued by symbol back in the day.

Can I ask for you to post the latest code of pdf417.bas ,I can't open the author's homepage in china，Thank you very much

Hello,
I could not paste the code because it is too long for a forum post.

Here is the module in att and also the font.
The font is in a zip archive because the forum doesn't allow to insert ttf files.

The first function in this module is my function and how I'm using it.

modPDF417.bas

pdf417.zip

Hope this helps.
