CScrollView::GetDeviceScrollPosition
Call GetDeviceScrollPosition when you need the current horizontal and vertical positions of the scroll boxes in the scroll bars.
CPoint GetDeviceScrollPosition( ) const;
Return Value
The horizontal and vertical positions (in device units) of the scroll boxes as a CPoint object.
Remarks
This coordinate pair corresponds to the location in the document to which the upper-left corner of the view has been scrolled. This is useful for offsetting mouse-device positions to scroll-view device positions.
GetDeviceScrollPosition returns values in device units. If you want logical units, use GetScrollPosition instead.
