 Usage Notes
   ■ Scroll bars are tools for navigating quickly through a long list of
     items or a large amount of information, or for indicating the current
     position on a scale.
 
   ■ Scroll bars can be used as input devices or as indicators of speed or
     quantity - for example, to control the volume of a computer game or to
     view the time elapsed in a timed process.
 
   ■ Use the Attached property to determine if a scroll bar is attached to a
     form. See: ◄Attached Property►
 
   ■ When you're using a scroll bar as an indicator of speed or quantity
     or as an input device, use the Max and Min properties to set the range
     appropriate for the use of the control.
     See: ◄Max Property►  ◄Min Property►
 
   ■ To specify the amount of change to report in a scroll bar, use the
     LargeChange property for clicking in the bar, and the SmallChange
     property for clicking the arrow at either end of the bar. The scroll
     bar's Value property increases or decreases by the amounts set for the
     LargeChange and SmallChange properties.
     See: ◄LargeChange Property►  ◄SmallChange Property►
 
   ■ You can position the scroll bar at run time by setting the Value
     property between 0 and 32,767, inclusive. See: ◄Value Property►
 
   ■ Horizontal and vertical scroll bars differ only in their orientation.
     Dimensions correspond to the Height and Width property settings.
     See: ◄Height Property►  ◄Width Property►
 
   ■ The minimum sizes for scroll bar controls are 1 x 2 (horizontal) and
     2 x 1 (vertical). Specified settings that are less than the minimum
     value allowed are set to the minimum value.
