Programming Excel with VBA
If your worksheet contains more than one set of OptionButton controls, you must ensure
that each set of OptionButtons has a different GroupName property. Otherwise, all
OptionButtons become part of the same set.
NOTE
ScrollBar control
The ScrollBar control is useful for specifying a cell value. Figure 42.6 shows a worksheet with three
ScrollBar controls. These ScrollBars are used to change the color in the rectangle shape. The value of the
ScrollBars determines the red, green, or blue component of the rectangle’s color. This example uses a few
simple macros to change the colors.
FIGURE 42.6
This worksheet has several ScrollBar controls.
The following is a description of the most useful properties of a ScrollBar control:

Value: The current value of the control.
Min: The minimum value for the control.
Max: The maximum value for the control.
LinkedCell: The worksheet cell that displays the value of the control.
SmallChange: The amount that the control’s value is changed by a click.
LargeChange: The amount that the control’s value is changed by clicking either side of the
button.
The ScrollBar control is most useful for selecting a value that extends across a wide range of possible
values.
