how to get if user selected item or not

if user no item selected then will _GUICtrlMenu_SetItemDisabled

if user selected a item then will _GUICtrlMenu_SetItemEnabled

like my function

Func menu($FileView,$hmenu,$Name1)
$p  = _GUICtrlListView_GetItemCount($FileView)
For $i = 0 to $p
$Name = _GUICtrlListView_GetItemSelected(GUICtrlGetHandle($FileView),$i)
If $Name = False Then 
For $i = 1 To $Name1
        _GUICtrlMenu_SetItemDisabled(GUICtrlGetHandle($hmenu), $i)
    Next
EndIf
ExitLoop
If $Name = True Then
    For $i = 1 To $Name1
    _GUICtrlMenu_SetItemEnabled(GUICtrlGetHandle($hmenu), $i)
    Next
EndIf
Next
EndFunc

[BugFix]

To got an event in the moment of listview item are checked/unchecked with mouse or spacebar the following code works fine. You can combine it with your menu-settings.

expandcollapse popup

#Include <WindowsConstants.au3>
