check which item is selected in a ListView control

Recommended Posts

Zomp

Which is the simplest way to check which item is selected in a ListView control just after it has been selected?

I would not want to use a loop to scan every item in the ListView, but I have also recognized that I cannot use the identifier of the ListView with GUIGetmsg().

I have read in some past threads on this forum some examples which use the GUIRegisterMsg($WM_NOTIFY,...) function. Can I ask if there is something simpler?

At present I'm using the following lines just after a select ... endselect code about GUIGetmsg():

$ItemLine=stringsplit(Guictrlread(GUICtrlRead($ViewListControlInGUI),0),"|")
$ItemName=$ItemLine[1]

A simple search in the Help would have led you to use #include <WindowsConstants.au3> as the 3rd include.
