I have Ghostscript installed and the printer so I can SaveAs PDF! from the IDE and standard apps. From within IIS I get a zero byte file.
I wrote an IIS extension in C that uses PBNI to allow me to run PB code directly from a PBL within IIS. I am trying to save a report to PDF so I can then read it into a blob and return it to the browser. I am suspecting a permissions issue. I am guessing that deploying a .Net component to IIS would have the same issue.
HTH
