How can I choose the location of the database file....

Can anyone help me with an example of how I can have my users choose the
location of the database file when the program starts up? I am working with
VB.net 2005 looking at an Access Database. I know I can put a default
database in the install but I need to know how to allow the user to look in a
different place to see the central database.


eg ... database saved to different folder..
program .. app.path

so if I decide to store the database in a shared folder...and install my
program on multiple computers on the network..

Advice... Articles....Code... Help...
Thanks for any input you can give on this.
