Sample project for Delphi 7

Exist any FUNCTIONAL sample project (conversion DOC a XLS to PDF and PDF/A) ?

I try it for 3 days without success.

I found one example on http://groups.google.com/group/borland.public.delphi.thirdpartytools.general/browse_thread/thread/331f3460fc2fff4b but it does not work too.

My version is 0.9.8.

Thank you, Pavel
