The SetScrollRange function sets minimum and maximum position values for the given scroll bar. It can also be used to hide or show standard scroll bars.
hwnd
Identifies a window or a scroll bar, depending on the value of fnBar.
fnBar
Specifies the scroll bar to be set. This parameter can be one of the following values:
| Value | Meaning |
| SB_CTL | Sets the range of a scroll bar. In this case, the hwnd parameter must be the handle of a scroll bar. |
| SB_HORZ | Sets the range of a window's horizontal scroll bar. |
| SB_VERT | Sets the range of a window's vertical scroll bar. |
nMin
Specifies the minimum scrolling position.
nMax
Specifies the maximum scrolling position.
fRedraw
Specifies whether the scroll bar should be redrawn to reflect the change. If this parameter is TRUE, the scroll bar is redrawn. If it is FALSE, the scroll bar is not redrawn.
This function does not return a value.
An application should not call this function to hide a scroll bar while processing a scroll-bar notification message.
If the call to SetScrollRange immediately follows the call to the SetScrollPos function, the fRedraw parameter in SetScrollPos should be zero, to prevent the scroll bar from being drawn twice.
The default range for a standard scroll bar is 0 through 100. The default range for a scroll bar control is empty (both the nMin and nMax values are zero). The
difference between the values specified by the nMin and nMax parameters must not be greater than 32,767.
