Take a look at the example, that is the best way to learn!
Here are the basics:
i- you're going to create your table that house your info. in this table
you will create a field to store the path/file.
ii- Using your form you will have a control that use the path/file field as
it's controlsource.
a) create a button with a click event that opens a file dialog (
http://www.mvps.org/access/api/api0001.htm ). Basically, when your user
click the button a browse dialog will open so they call go and select the
file in question. you then pull the path/file name from theri selection and
use it to populate your control which in turn add it to the table.
b) for this specific control, create a click event that uses the
followhyperlink method so that when your users select/click on the control it
will open the file for them.
Application.FollowHyperlink Me.YourControlName
And you're done!
Look at the sample and try an link what I just said to them so you can
understand the coding and sequence of events.
