You should use ControlListView w/ "GetText" instead

faustf,
 

As the Help file explains, you need to use GUICtrlRead twice to get the text from a ListView - first to get the ControlID of the selected item and then again to get the content.  You actually do this a few lines later in your script:

$sSelected_Data = StringTrimRight(GUICtrlRead(GUICtrlRead($List4)), 1)

So you need to do the same thing if you want to check the value beforehand.  :)

Furthermore, why are you using the "advanced" flag when trying to display the content?  All that does for ListViewItems is to return "The state of the ListViewItem if $LVS_EX_CHECKBOXES exStyle used" as also explained in the Help file.  Well worth reading it carefully when things do not seem to work as expected. ;)

How come you are using Local $test = GUICtrlRead($List4, 1) in one line but using $sSelected_Data = StringTrimRight(GUICtrlRead(GUICtrlRead($List4)), 1) in another line? Either you're using code you don't understand or you made a mistake somewhere. Because the second line will read the text of the ListView item, and the first one will read the index of 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.

This maybe relates to your issue as well. The On_Button3 function does not know what the variable $List4 is. You probably need to either declare it globally or pass it's value to the called function.
