AlienStar,

I imagine it is because you have added items using the _GUICtrlListView UDF functions and not the native GUICtrlCreateListViewItem function. Thus there is no ControlID for GUICtrlRead to use. Try using the native function to add the elements to your ListView and you should be able to read them.

would you tell me how to solve please ?

You can use the _GuiCtrlListView functions for example:

Local $idListView_rd = _GUICtrlListView_GetItemTextString ($idListView, Number(_GUICtrlListView_GetSelectedIndices($idListView)))
