Does anyone know a function to determine if a Point exists within a polygon?

Question

Edit: I'm using C# with ArcEngine10.

do you mean function in a spatial database or some API with spatial functions (if so, which language)? — Mario Miler, Sep 8 '10 at 19:40

Take a look at the IRelationalOperator2 you can cast your polygon to that Interface and use the contains method.

If you don't want to use Arc, take a look at Graphics Gems IV http://tog.acm.org/resources/GraphicsGems/

there are 2 articles with code for the point in polygon problem
