He He he, I just thought I'd throw in my two cents here.  Cause I mean,
we're talking about trying to fetch the String that is stored in the
list view, to make our comparison, correct?

Well, just for kicks and giggles, why not assign LVITEM_lParam a Memory
location to the string that's being used? That way, in your sort function,
all you have to do, is peek() the memory location in the two lParam's from
the LVITEM_lParams, to see where to move it.   Just quirky that way I guess.

As far as I'm concerned, the LVITEM_lParam can be anything, so you could
legally assign a Memory Location that holds the String into it.
