            I am working on an rpg. I would like to have a number of tiles that I can place
            in certain places to form the walkable world.  Is ther some way I can assign a name
            to each tile and set up a data table of some sort? I wold also like to make some that
            you can't walk through such as walls, but have some that you can such as grass. Is
            this posible, and how would I set it up?

Ah yes, the old Adventure game.  I remember writing those things...

You need two things.
1. A global user defined type such as:
  Public Type tLocation
    Description As String  'Such as "You are in a garden"
    ExitNorth As Boolean   'True or false depending on wether they can move north
    ExitEast As Boolean     'Same as above
    ExitSouth As Boolean    'Ditto
    ExitWest As Boolean     'Ditto
    Contents As String ' Things in the room comma delimited "Sword, Map, Lamp"
    'Other things you might describe for each room
  End Type

2. You need an multidimension array for your "map"
  Global MapArea(100, 100) As tLocation
    'This gives you a single level 100 rooms wide by 100 rooms long.
    'If you want multi levels, try
  Global MapArea(10, 100, 100) As tLocation
    'This would be 10 levels by 100 rooms wide by 100 rooms long.

After this come the hard part.  Assigning values to each room during the application startup.  For example, the assignment for the room at the farthest north, farthest west, would look like this:
  MapArea(1, 1).ExitNorth = False 'You can't move north
  MapArea(1, 1).ExitEast = True   'You can move east
  MapArea(1, 1).ExitSouth = False 'Can't move south
  MapArea(1, 1).ExitWest = False  'Can't move west

You will need to duplicate this type of code for each room.  Unfortunately, VB doesn't have Read/Data statements which is what used to be used for this, however, VB does work well with databases so you can load your info from there.

It's a lot of work, but a lot of fun when you're done.  Good luck.

The above answer is enough to get you going.  If you would like, for you only (not for others that may view this answer).  I can send you a some demo code written in VB5 which will show you exactly what I'm talking about.

You will have to post your email address, though.
