when i try to read $list4  not read  give me  always  0  

Local $test=GUICtrlRead($List4,1)
        MsgBox(0,'',$test)

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.

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.

Show us more code, so we can run it and see what is really going on.

Alternatively, try the sugestion in the 2nd post.
