SBM_SETRANGE
An
application sends the SBM_SETRANGE message to a scroll bar control to set the
minimum and maximum position values for the control.
SBM_SETRANGE
wParam = (WPARAM) nMinPos; // minimum scrolling
position
lParam = (LPARAM) nMaxPos; // maximum scrolling
position
Parameters
nMinPos
Specifies the
minimum scrolling position.
fMaxPos
Specifies the
maximum scrolling position.
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
The default
minimum and maximum position values are zero. The difference between the values
specified by the nMinPos and nMaxPos parameters must not be
greater than the value of MAXLONG.
If the
minimum and maximum position values are equal, the scroll bar control is hidden
and, in effect, disabled.
