Microsoft does not recommend nor support using the Office COM objects for server operations.
>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. > -----Original Message----- > From: Discussion of advanced .NET topics. > [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.
