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.
