int SetScrollPos( int nBar, int nPos, BOOL bRedraw = TRUE );
nBar
Specifies the scroll bar to be set. It can be one of the following values:
| Value | Meaning |
| SB_CTL | Sets the position of a scroll-bar control. In this case, the CWnd must be a scroll-bar control. |
| SB_HORZ | Sets the CWnd horizontal scroll-bar position. |
| SB_VERT | Sets the CWnd vertical scroll-bar position. |
nPos
Specifies the new position. It must be within the scrolling range.
bRedraw
Specifies whether the scroll bar should be redrawn to reflect the new position. If bRedraw is TRUE, the scroll bar is redrawn; if FALSE, it is not redrawn.
Sets the current position of a scroll box to that specified by nPos and, if specified, redraws the scroll bar to reflect the new position.
Setting bRedraw to FALSE is useful whenever the scroll bar will be redrawn by a subsequent call to another function.
The previous position of the scroll box.
