SBM_SETPOS

  • Article

This message is sent by an application to a scroll bar control to set the position of the scroll box (thumb) and, if requested, redraw the scroll bar to reflect the new position of the scroll box.

SBM_SETPOS wParam = (WPARAM) nPos; 
  lParam = (LPARAM) (BOOL) fRedraw;

Parameters

  • nPos
    Specifies the new position of the scroll box. It must be within the scrolling range.
  • fRedraw
    Boolean value that specifies whether the scroll bar should be redrawn to reflect the new scroll box position. If set to TRUE, the scroll bar is redrawn. If set to FALSE, the scroll bar is not redrawn.

Return Values

If the position of the scroll box changed, the return value is the previous position of the scroll box; otherwise, it is zero.

Remarks

If the scroll bar control is redrawn by a subsequent call to another function, setting the fRedraw parameter to FALSE is useful.

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Commctrl.h.
