Something like adding a value to an area of an image

Question

If you have a floorplan showing all the rooms. Is there a way to click on one of the rooms and then use that value to display data about that room retrieved from a database. Obviously I need to do something about that image first like drawing a transparent rectangle and giving this a value but I have no idea how to do this. Can anyone help? Thanks.

Well first I advise you to learn how to draw using GDI+ something that isn't too hard to learn. Displaying data from a database when you click on a room however requires you to be able to connect raw mouse coordinates with a room which is a lot more work and probably not a good idea to attempt if you don't already have a vague idea of how to do it especially if the room is not a rectangle. Basically there are no pre-made classes to help you with the floorplan part beyond drawing it so you will have to write your own.
