SBM_SETRANGE message

The SBM_SETRANGE message is sent to set the minimum and maximum position values for the scroll bar control.

Applications should not send this message directly. Instead, they should use the SetScrollRange function. A window receives this message through its WindowProc function. Applications which implement a custom scroll bar control must respond to these messages for the SetScrollRange function to work properly.

Parameters

wParam

Specifies the minimum scrolling position.

lParam

Specifies the maximum scrolling position.

Return value

ComCtl32.dll version 5.0: If the position of the scroll box changed, the return value is the previous position of the scroll box; otherwise, it is zero.

ComCtl32.dll version 6.0: The current position of the scroll box, regardless of whether it has changed.

Remarks

The default minimum and maximum position values are zero. The difference between the values specified by the wParam and lParam parameters must not be greater than MAXLONG.

If the minimum and maximum position values are equal, the scroll bar control is hidden and, in effect, disabled.
