IMHO this is really a maths question that's not related to .NET per se. Not
being a maths major I can't really help you unfortunately :-(

But the basic idea is that you'd have the necessary co-ordinates that define
each shape, and using a mathematical formula you could determine within what
shape any arbitrary point falls. Regardless of what language you use, you've
still use the same mathematical equations.

Cheers

: I need to build a world map in .NET.  The onClick
: event of an ImageButton object supplies the X and the
: Y.  The image map I was given to work on is all in
: polygrams so just knowing the X and the Y doesn't
: do necessarily accomplish anything unless X and Y
: match a point exactly on the polygram.  Databasing
: each pixel on the map and its corresponding
: country isn't exactly a streamlined process.

: Any thoughts, other than don't use .NET, would be highly welcome.
