Use to get or set the topmost visible line (zero-based).
Notes
Use this property to determine the first visible line; set this property to scroll the control. Setting it to the last line or beyond the last line will simply move the vertical scrollbar's thumb to the bottom, not necessarily displaying the last line at the top of the control.
