Modifying the Control Bitmap

When ControlWizard creates the Circle control classes, resources, and other files, it also generates a bitmap file called CIRCCTL.BMP. This bitmap represents the control as a tool palette. Tools such as Visual Basic load this bitmap from the Circle control and display it in a palette. The palette provides a pictorial representation of all the controls that are available to the user.
