void GetScrollRange( int nBar, LPINT lpMinPos, LPINT lpMaxPos ) const;
nBar
Specifies the scroll bar to examine. The parameter can take one of the following values:
Value | Meaning |
SB_CTL | Retrieves the position of a scroll-bar control. |
SB_HORZ | Retrieves the position of the CWnd horizontal scroll bar. |
SB_VERT | Retrieves the position of the CWnd vertical scroll bar. |
lpMinPos
Points to the integer variable that is to receive the minimum position.
lpMaxPos
Points to the integer variable that is to receive the maximum position.
Copies the current minimum and maximum scroll-bar positions for the given scroll bar to the locations specified by lpMinPos and lpMaxPos. If CWnd does not have standard scroll bars or is not a scroll-bar control, then the GetScrollRange member function copies 0 to lpMinPos and lpMaxPos.
The default range for a standard scroll bar is 0 to 100. The default range for a scroll-bar control is empty (both values are 0).
