Are you familiar with Automation? If not I would like to refer you to a very good book on programming Access.
Title: Programming Access 2000 Professional
Publisher: Wrox Press
Price: 45-55 dollars
NOTE: In order to do what you want to do, will require what is called Automation. This basically is nothing more than accessing the properties,methods and objects of any given application within MS Office. In your case MS Word. I reccommend a book to you for two reasons. Their is too much code and directions to put in a post and you would learn more about it, if you had a reference manual on the subject.
Once you get a feel for Automation, you will then see how powerful it can be, especially to the Access programmer and you will be able to incorporate it in many of your future applications...I know, I use it all the time.
I hope this helps!!
Don't do today, what can be done tomorrow.
