I'm hoping someone here can give me a hand. I have an Oracle database that contains approximately 35,000 nodes and 35,000 segments. I want to be able to plot these onto a form (or picture box or whatever) in VB 2005.
The intent is to be able to draw a map of sorts such that you can zoom in on one area or pan around the map. This can be a problem since 35,000 nodes and segments can take a long time to draw. So I'm looking for the best way to do it.
Here's the catch. The nodes cannot be "dumb" graphics. I need events for these nodes to accomplish certain tasks when the user clicks on them, etc. So for the nodes, I'd need some kind of control with events.
