CIRC Attributes Sample: Demonstrates Using Property Pages

The CIRC attributes sample shows how to use ATL to make a simple ActiveX control. The sample creates a control that draws a circle and demonstrates property pages, control painting, use of color and caption properties, Click and KeyPress events, and a Color property page.

The CIRC sample is the nonattributed version of this sample.
