I am creating PDF reports. I know some basics and try to make them simple. But still, they look ugly. I would like to see some good examples. Are there good looking reports on the web?
If you'd like to write good looking reports you should probably look into LaTEX.
An example report, generated with LaTEX: http://maths.dur.ac.uk/Ug/projects/resources/latex/report/report.pdf
If you are using Java, Dynamic Jasper generates good looking reports out of the box
See here example of web-reports + PDF. I forget good link to online demo of FastReport.Net - there is better.
There are many ways to create PDF reports depending on your application platform (desktop application, web application etc) Having done alot of both, the easiest and best ways I have listed below:
Web Applications - most essential is HTML-to-PDF creation, where you simply need to point the PDF generator at a URL and it converts it. Simple.
iTextSharp (.NET)(Open Source) - http://sourceforge.net/projects/itextsharp
iText (Java)(Open Source) - http://itextpdf.com/
ABCPDF (.NET) - http://www.websupergoo.com
Desktop Applications - an easy interface make life much easier
DataDynamics ActiveReports (.Net) - http://www.datadynamics.com
