I need to make a user interface which features an interactive map, where all

Hi,

Doing that manually is very hard work, especially if you have no
experience doing it.
Take a look at either google maps or MS virtual earth. you would need
internet connection to run the application though.

Are you familiar with the PaintBucket tool in Microsoft's Paint
application? Basically I would need the same exact algorithm for when
I need to fill states in with color... when the user clicks a spot
within the state's boundary (mapped from the bitmap file) it's just as
if someone using Paint used the PaintBucket on a solid colored shape.

Use a flood fill algorithm. Keep a list of "points that need to be
coloured", and each time add all the uncoloured points immediately
surrounding points already in the list. Stop at the state boundaries.
