ghost question

Hi everybody,


I would like to ask a few question about GhostScript and ghostview. =
First of all, I would like to develop an ActiveX that is able to display =
a PDF in a web page. I have a functional prototype based on gswin32.exe. =
However, since gswin32.exe is a command line application, there is stdin =
and stdout interaction with the user and ghostscript seemed to be drived =
by thoses commands.

My prototype simply block on the stdin callback, wait for the user click =
on a button labeled "next page". Once this button clicked, the message =
is sent to the main thread and a new line is copied in the stdin buffer. =


I know there is better way to handle this situation, but the =
documentation is really not complete for Win32 applications. =
Additionnaly, I still don't how to display previous pages (go back).

I tried to traced gs view code to see how it's implemented, but it's =
very BIG and hard to trace. So that's why I ask on this list for a few =
HINTS to ghostscripts experts.


What are the best way to drive ghostscript from Windows application ( =
user click buttons, menus etc) ? What about gs_run_string ? Are those =
thousands of postscripts files necessary(what would be a minimal script) =
?


thanks you very much.
