Hello Milton Neal, thank you very much for the quick response. With your fix, the issue is resolved. We can fully use your library now in our company. have a nice day!
-
Hello beytullah gueneyli The issue was a typo in MessageProcessor.cs file. I had 254 instead of 255 for the AI. This is fixed now and have uploaded it to the repository. You can download the file and re-compile the source or download the binary. Let me know how you get on. Cheers Milton

Fix typo in MessageProcessor.cs for AI255

title should be "Databar expanded stacked barcode with AI 255 not working". sorry for the confusion
-
Hello, First of all, thank you for porting the Zint library to C#. In our company, we are using this project to generate database expanded stacked barcodes. The barcodes we generate have the application identifier of [255] which represents a GCN (general coupon number). Unfortunately, the generation fails with an ZintNetDLLException with the message that the Application identifier is invalid. When I run the portable original Zint application and enter the database expanded stacked barcode, it works....

Hi Vadim Thanks for the feedback. I've re-check all the dm code and all appears correct. Hopefully we have sovled all the issues. :)

Vadim Cherevkovsky posted a comment on ticket #9
Hello Milton! I checked a big list of our barcodes with the new patch, they all generated correct now. (I wrote a small application for barcode checking. It uses a handheld barcode scanner in automatic mode. A list of source string is loaded into the app and it displays generated barcodes one by one, waiting a response from scanner. When response is receved, next barcode is shown, otherwise the app shows an error message.) Thank you again.

Hello, Milton! It seems that it's ok now 010468006519912121SOIP5XD3XtmjV 91002A 92WSV7Nv2lqcL3YH/Fm5hjs4klyF7LjRjojuu2Jhvga/T4ZtH2rJg6WSvn6GsIO7c6VR+Mae8VpqyulBpX/GRP+Q== I'll rebuild my application with your latest patch a bit later and check it once again. Thank you!

Hello Milton All our existing labels generated correctly, but we found a new string which causes unreadable barcode: [01]04680065199121[21]SOIP5XD3XtmjV[91]002A[92]WSV7Nv2lqcL3YH/Fm5hjs4klyF7LjRjojuu2Jhvga/T4ZtH2rJg6WSvn6GsIO7c6VR+Mae8VpqyulBpX/GRP+Q== I hope it will help to find another reason. Thank you.

ECI bug fix
-
Hello Vadim As you may know the ZintNet library is a port of the C Zint library. So a lot of code was converted from C to C#. Some of the issues were typing errors in converting the code. Some were bug fixes in the original Zint C code which I hadn't applied to the ZintNet code. In my code I found that an ECI was being inadvertently added the beginning of the symbol, which shouldn't have affected scanning of the barcode, as all you lastest samples scanned correctly with my scanner. I'll look deeper...
-
For example, some more strings which caused unreadable barcodes. I can't see, what they have in common...
-
Hello, Milton! What was the exact reason of this bug? How can I find which strings caused this behavior of the library? I'll explain. I work for company that has a huge amount of barcodes for special labels used in its production process. And we want to find which barcodes was generated incorrectly to reissue the labels with them. It's impossible to reissue all labels, so we want to replace only defecive labels. Thank you.

Hello Anthony, Yes the module is mine. I have update the assembley attributes and re compiled the dll. It now has the correct copyright info etc for the dll. I have uploaded it, so you download it and update your source. Regards Milton

-
Hello Milton, I am still a bit confused. The ArrayEx.dll included in the project has a copyright of "Copyright © Hewlett-Packard 2017" Are you saying that you wrote that module? I realized that the ArrayEx.cs in the project was not used. I was hoping that it was your attempt to remove that dependency. Anthony
-
Hi Anthony, ArrayEx.dll was a module I wrote severall years earlier for another project, decided to use it for ZintNet. It has nothing to do with HP other than the computer I wrote the code on was a HP with the computer name Hewlett-Packard, in which Visual Studio picks as the default developers name. In saying all this, I should update this old module , though I have been tossing up to re-write some of the code and do away with this dll altogether. The ArrayEx.cs is in the code repository but not...
