2D Barcode not working for Alphabets

Jan 9, 2010 at 2:26 AM


The Web Application is working for rendering digits. But when I include alphabets in the input text, it's throwing an error 'Filename is not valid'.

Can you tell me why is it giving such an error message? What are the changes I need to make to make it work with Alpha-Numeric Values...


Also, I am having a tough time debugging the application. I want to see how the PDF417 barcode is being rendered. When I put the break point, i am able to step through the code. But I can't understand which event/function is calling the code. Can you please let me know how are the functions in CodePdf417.cs file are being called?


Thank you very much for your kind co-operation!!!

Stumbled into the same problem and to me it looks like the problem is in the file BarcodeImageUri where there is a line saying which characters that are valid to use. Lowercase characters are not allowed according to the row below.


 It should be rather easy to change for some developer.
