A* Pathfinding Example in VB.Net

This is a A* pathfinding example to illustrate how to implement a A* pathfinding algorithm into your program. It's a port from Patrick Lesters example in BlitzBasic to VB.Net. It uses a Binary Heap class I made to sort the score values. It's very rough around the edges and needs alot of work to be anything more than an example. Let me know what you think.
