For example, if you wanted to create a control that changes its appearance by cycling through a range of pictures, you would repeatedly call the function below (or a more terse equivalent):

{
	int					Val, Max, Min;

	Val = GetCtlValue(ControlHandle);
	Min = GetCtlMin(ControlHandle);
	Max = GetCtlMax(ControlHandle);

	Val++;	/* Increment Val to move to the next picture in the series */
	if (Val > Max) 
		Val = Min;

	SetCtlValue(ControlHandle, Val);
}
