Opening a File Selection window from VBA

I am working on a vba sub-routine that will create a project file that we can send to our customers.  The procedure will remove any confidenital information from the plan and save it a local file. 

I would like the user to select the destination using a standard windows file selection window. 

How can i do that?

Is there a function I can call?  Do I need to create a form?

Thanks in advance for your help,

Craig
