Ok what I'm trying to do is that I have over 400+ .doc and each one is very similar but a little difference and I'm trying to modify only 2 fields that is in every document(which is a revision number and rev. field to enter in more data for the new revision); there's pictures and text only in them. Also need find a way to make it modify like around 5-10 of these files a time. My question is how to approach this project and what programming language to use or should I make just a addin for MS Word? I'm trying to create it to remove having to update 400+ files just to enter in new data for the revisions. Thanks in advance.
