You can break the document in three sections: header, body, trailer, and
then protect the first and last. Not fool-proof, but if you don't mind
having section breaks in the document, it might be sufficient. There's no
other way to make parts of a document read-only. Forget about trapping the
insert etc events. Alternatively, don't worry about it while the user is
editing but check, in the Document_BeforeSave event, whether the header and
trailer are as you need them to be and correct if necessary.

Use early binding. Declare your Word application reference 'with events' and
put the appropriate event code in your VB app. However 'take back control'
is a slightly dubious concept in an object-oriented language like VB. But at
least your app is notified that the user has closed with the document or
quit Word.
