Help with API

[mtrack81]

I went to this link that someone in this forum gave me for Access 97..
http://www.mvps.org/access/api/api0006.htm
The problem is that what I really want to do is to prompt the user to enter a file, but the format i want to do it in is similar to the (find file) format that is used in windows start menu. Is there anyway to code this?
