SBM_SETRANGEREDRAW

An application sends the SBM_SETRANGEREDRAW message to a scroll bar control to set the minimum and maximum position values and to redraw the control.

SBM_SETRANGEREDRAW

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.
