Hello, This is Vikash Gohil.
I don't know whether this is the correct forum for my Query.
My Query is I want to print barcodes in Crystal Reports and use the report in ASP.net application.
Using report in ASP.net I have the Idea, but how to print Barcodes in the report.
Is there any in-Built functionality in Crystal Reports for Printing Barcodes or Do I have to use any 3rd party tools.
Please anyone who has done this before or can provide me some idea, would be of great help.
Awaiting for a reply soon.
Thanks in Advance.
