Sorry, I have used the release 1 exe. With release 2 (forms) exe this works. BUT, the output is useless. i.e. It's not a 100% match with the PDF output. lots of lines between records and no graphics and it's not useful as an excel sheet.
Hmmmm.... yes... There's an explanation though... Oracle Reports sucks! I am currently battling with Oracle Reports and it's utilisation of fonts (or the lack thereof). Very frustrating component. Actually, Oracle does not do anything UI well.
If you want nice Excel output from Oracle, then either develop a .NET Stored Procedure (only available on windows) that automates Excel to produce output, or use POI.
I have been using POI for around two years now with varying degrees of success.
