Detecting acurate scrollbar position?

[Brian van der Beek]

I have an application with a CListCtrl. Items are continuously being added to this list. When I scroll the box of the CListCtrl to the end of the scrollbar I want the list to autoscroll. To accomplish this I retrieve the scrollbar position (GetScrollPos) and compare this to the scrollbar limit (GetScrollLimit). If there is a match is call EnsureVisible after adding an item. However when I slowly drag the box of the scrollbar, the scrollbar position will never match the scrollbar limit. It seems the limit is updated during dragging and the position is not. Anyone knows a solution for this problem?
