You're right! That's why we used the helper application.

From http://support.microsoft.com/kb/257757/
MORE INFORMATION All current versions of Microsoft Office were designed, tested, and configured to run as end-user products on a client workstation. They assume an interactive desktop and user profile, and do not provide the level of reentrancy or security that is necessary to meet the needs of server-side components that are designed to run unattended. Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when run in this environment. If you are building a solution that runs in a server-side context, you should attempt wherever possible to use components that have been made safe for unattended execution, or find alternatives that allow at least a part of the code to run client-side. If you choose to use an Office application from a server-side solution, you will find that it lacks many of the necessary capabilities to run successfully, and you will be taking risks with the stability of your overall solution.

[mailto:[EMAIL PROTECTED] On Behalf Of Peter van der Weerd Sent: Monday, December 11, 2006 3:03 PM To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Subject: Re: [ADVANCED-DOTNET] Does anyone know how to read a Word document in .Net 2003? We used Automation with MS Word succesfully in a server condition. However, we had to make a few design decisions: 1) Due to the fact that Word is written as a UI-application you must be prepared that messageboxes might occur, stopping your application. We wrote code to auto-answer some of those boxes, and cancelled the conversion if we didn't know what to answer. 2) If you want to load many documents in a loop you will end with a crashed application... We used Windows to do the cleanup by writing a helper-application that does the Word automation. The server-app then starts this helper-app for each document that must be converted. The server is able to set a timeout for the conversion and cancel helper-app if it lasts too long. The helper-app itself can listen to an Win32-event to kill itself.
