How to read author-information from an office file?

Question

I have a bunch of office 2003 documents (.ppt, .doc, .xls) in a folder, and need to extract the "author" property from each file. What would be the best way to do this, is there some sort of (free) office-api I could use to read this information?

I'm using .NET 2.0

Answer 2

This post contains some code for accessing MS Office file properties.

A codeproject article - it's in c++, but it might be useful.

This looks like the most promising article.

Answer 3

I found an article on MSDN about Dsofile.dll which seems to work as expected. Other suggestions are still welcome.
