Remarks

Prepares the container for painting, gets the control's client area, then calls the control class's OnDraw method.

An OnDraw method is automatically added to your control class when you create your control with the ATL Object Wizard. The wizard's default OnDraw draws a rectangle with the label "ATL 2.0".
