AutoCAD VB :: Public Shared Variables

I have several variables I want to be able to set and then use throughout my project.

First, and seems simplest, would be to just Public Shared the variables. Set them as required, call them when needed.

Second would be to create an object and assign the variables as properties to that object. It would take more programming to do this option. The beauty of this would be that I could store the values from drawing session to drawing session and would not have to ask the user for the values every time he starts my program. Can this be a custom dictionary object? Is that how you would design it?

Unless there is a way to make my Public Shared variables hold their values when the drawing is closed. Static doesn't seem to work here, but I could be missing something.
