HScrollBar control
An HScrollBar is a horizontal bar with arrows at either end and a
scroll box. Typically, you use an HScrollBar control as a slider control
employed by users to specify a value on a continuous scale, or as a way to
display graphically information to the user.
Usage note
The HScrollBar control is not the horizontal scroll bar that
displays to allow the user to scroll through information in a
control.
