CDragListBox, can't drag to end of list.

I'm using the CDragListBox. I can't drag an item to the end of the list. I have to drop it one up from the end and then drag the last item up above it.  What might I be doing wrong?

I don't think you're doing anything wrong. Looking at the source for CDragListBox, the virtual function Dropped() is called when you drop the items. However, if you look at the source for the function, there is a call to ItemFromPt() that tries to determine what the source and destination indexes are. If any of them is -1 (which means outside the range), then the function does not do anything. You should override this function in your subclass of CDragListBox and do something more intelligent when you drop it at the bottom.

A simple but not very elegant solution is to put a blank item at the end of the list. The Dropped() function can be overridden to prevent dropping the blank item if it's dragged. This will ensure that the last item is always blank.
