Spell Check ASP.NET Word 2003

Hi,

I have added a spell checker to my web application using the "Microsoft Word
Document" DCOM. Everything works great in my development environment. When
I move everything over to my production machine I get...

"Object reference not set to an instance of an object"

This is caused when the following Visual Basic line is executed...

"ThisDocument = WordApp.Documents.Add()"

I have everything working in my development environment. I have tried
several iterations of this spell check code and I have had it working
perfectly 3 differents time with relatively the same failed result on the
production server. The only thing I can narrow it down to is permissions in
IIS and DCOM. My development machine is running WinXP and IIS 5.0. My
production machine is Windows 2003 Server Standard edition. I have my dev
machine accessing the DCOM under the ASPNET account and the prod machine
accessing under the NETWORK SERVICE account. I can't seem to fiure it out.

A good possibility is that you didn't reference the PIA for accessing the
Word component. For security reasons, you must use the PIA (Primary
Interoperability Assemblies) for Office if you want to distribute your
application to other machines and not an interoperability assembly generated
by VS.NET (or you must compile the application directly on the target
machine if you don't want to use the PIA).

See "Referencing the Office XP PIAs" in:
http://msdn.microsoft.com/library/de...dc_oxppias.asp
to make sure that you have the correct reference.

Be warned that using Word directly on a server is probably a bad idea.

Thank you for the quick reponse.

I double checked the pia's installed on the server and everything seems
fine. I even re-installed them to make sure. I am simply using Word for the
spell checking functionality. It was already running Office 2003, so I
figured, why not. I still get the same error. Word is listied in the task
manager, but I can't do anything with it. It seems as if the application can
be started, but objects on the production machine cannot be created. weird.
Thanks again Sylvain!
