On my form I've got a picturebox, radio buttons and check boxes. The check boxes relates to a Square/triangle, in which a square/triangle will be displayed on the picturebox. And the radio boxes relate to rectangle/circle which are displayed when either radio button is selected. I have been told to create an array so that when of the radio buttons is checked, that the image is displayed uppermost (at the front). Any ideas of how to create this array and how to use it.
