Open, Save, and Print can all be done via the Common Dialog control. It's probably not enabled by default, so go to the Project menu, and go to Components, and scroll down and check the Microsoft Common Dialog control and hit OK. If you've got the MSDN Library cds that were included in VB (at least in the edition I got), they should be very helpful about how to use Common Dialog.
Find is a little bit harder to do, cuz IIRC it's not part of Common Dialog, but I am sure I've got some source code examples from my various VB books I have that I can post, if JohnM hasn't helped you with this already.
www.planetsourcecode.com is a really good place to get code samples, too.
