Yes, but the additional instances of the application wouldn't load =
additional objects into memory, just the information for them. Unless =
you specifically loaded the additional librarys into their own distinct =
memory space for resiliance.

You don't want to store objects against the application or session =
objects - if it's web-based, it needs to be stateless and that sort of =
thing leads to all kind of nightmares.

The idea somebody had previously of having a process that runs and polls =
a queue of "items to process" is a much better idea.

And yes, having a set of office libraries would make a huge deal of =
sense. But then that'd be too easy wouldn't it ;)

it will create an instance for each time Word is instantiated by the =
code
ApplicationClass WordApp =3D new ApplicationClass();

it could be avoided if one ApplicationClass instance is created and =
stored as in the ASP .Net Application object. this instance could be =
resued throughout the application.

just some ideas..

dunno about processor licences though..

I'm not very comfortable with installing Office on a production server.
Why isn't there a set of object libraries for server use ?
Does the sharepoint portal server have something for this ?
