1. Load a map into CE. This can be done by the image class.

2. Draw a circle at a specific location on the map image when the user selects an item from a combobox. Can this be done?
1) How to get the (0,0) coordinates of the image? Like in C#, I can get the relative coordinates in a picturebox by calculating it's position with the app window.
2) How to draw? Maybe the methods in the canvas class? A simple example can be very helpful.

3. Can I set different layers for the same window? I want something like an installation wizard process that can guide people from step 1 to step 2 till they finish it, and I don't want to use different windows. Probably I can use several canvases and hide them one by a time?

Thanks in advance.
