CListCtrl events
I am using CListCtrl,as I am going to show thousands of items in it.
So I want to show it in parts so that process will not slow down.
So if I will add first some items in ListCtrl then on scroll down event
next block likewise.But I couldn't see any scroll down event for this
ListCtrl in classwizard.So which event I can use for this process?
