Hi, we are writing a server app that would check the validity of the signatures on incoming word documents.

But apparently this needs Winword to run in the background (and hence it needs to be installed on the server) this results in quite a heavy load, and a potential for memory leaks and security issues.

So is it possible to alter a word document without having word opened ? (so all processing is done by the application using the libraries, and not word in request of the application)

We're using VS 2003 and the
C:\WINDOWS\assembly\GAC\Office\11.0.0.0__71e9bce111e9429c\Office.dll
and
C:\WINDOWS\assembly\GAC\Microsoft.Office.Interop.Word\11.0.0.0__71e9bce111e9429c\Microsoft.Office.Interop.Word.dll
dll's at the moment.
