Chapter 9.  Making the Most of Your User... > Create a Geographical Map Interface

9.3. Create a Geographical Map Interface

9.3.1. Problem

You want to display a map and allow users to click on regions of the map. You want the form to react based on which region is clicked on. The regions aren't necessarily rectangular. How can you do this?

9.3.2. Solution

You can accomplish this task using a combination of bitmaps and transparent command buttons. Depending on how far from rectangular your shapes are, this task may be trivial or quite involved. By making the command buttons transparent, you make the application appear to react directly to mouse clicks on the map.
