RE: Listview Item identifiers
As often happens I managed to solve most of this soon after posting! I
had addLV.. and setLV.. back to front. I mistakenly said that
setLVItemText uses the item Identifier whereas it actually needs the
current row Index. Found a post about LVFINDINFO and so have used this
to create a function called findLVItemIndex that returns the current
item index after being passed an item identifier. Seems to do the trick.
However, I would still like to know how to programmatically select and
focus a row in a ListView.
