Sorry there was originally 3 columns. But issue still is apparent?  When I click any of the list view items. Wm_notify says it's index 0 no matter which item I click

Works for me when you correct this line.

GUICtrlCreateListViewItem($x & "|" & $x + 1 , $listview)

Your script won't even display anything so I'm not sure you're testing this before you post it.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
