A value set control (WC_VALUESET window class), like a radio button, is a visual component that enables a user to select one choice from a group of mutually exclusive choices. However, unlike radio buttons, a value set can use graphic images (bit maps or icons), as well as colors, text, and numbers, to represent the items a user can select. This chapter presents the basics about value set controls and tells you how to create and use them in PM applications.
