Barcode Generation - InvalidCodeException Not Triggering

Aspose.BarCode Product Family

Hi Experts,


I am finding that during Barcode Generation - InvalidCodeException is not getting triggered even when I enter invalid data. I would like to perform a form validation to see if the user has typed a valid code text for Barcode generation and report immediately before really going for Barcode generation.

Currently even if enter special characters @^#%^#%, that too goes through fine without reporting any error. I have also tried following the exact code that is mentioned at <a href="https://forum.aspose.com/t/26881 and that too didn’t work.

I am using Aspose.BarCode_5.4.0 version for .Net 3.5 Framework.

Any prompt help would be highly appreciated as I am working on a time critical project.

Regards,
Joseph

Hi Imran,

Thanks for your prompt response. Unfortunately our license is valid only until the version I had mentioned.

Regarding sample code, the same code present in URL mentioned in my initial post itself doesn’t work; even for simplest barcode 3 of 9, it accepts special characters.

Please advise.

Regards,
Joseph

Hi Joseph,


Thank you for your inquiry. It looks like it accepts special characters, but actually prefilters code text before generation. I mean it generates the barcode without special characters and do not throw an exception regarding invalid code text. I recommended its latest version because BarCodeBuilder class holds ThrowExceptionWhenCodeTextIncorrect property. Please take a look over helping example topic here:
http://www.aspose.com/docs/display/barcodenet/1D+Barcodes+with+Optional+Exception+Message++in+case+of+Wrong+Code+Text

Secondly, you can get a temporary license for 30 days to evaluate our latest version. You can download a latest version of Aspose.BarCode from here:
