Copies the current minimum and maximum scroll-bar positions for the given scroll bar to the locations specified by lpMinPos and lpMaxPos.

void GetScrollRange(
   int nBar,
   LPINT lpMinPos,
   LPINT lpMaxPos 
) const;

Параметры

  • nBar
    Specifies the scroll bar to examine. The parameter can take one of the following values:

    • SB_HORZ   Retrieves the position of the horizontal scroll bar.

    • SB_VERT   Retrieves the position of the 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.

Заметки

If CWnd does not have a scroll bar, 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).
