Hey guys, After much searching and reading I Siao's example script from the below link is the closest to what I need to do. I have a ListView that is populated with the names of different configurations. When a Listview item is selected, a form is populated with that items data. Right now I have a column that shows which item's data is shown in the form, but it would be much cleaner to just have the current item highlighted. My problem is this - The highlighting in Siao's example works great, but inside the Listview when you select in the "empty" space to essentially deselect everything the highlighting disappears. How can I keep the last selected item highlighted when clicking in this empty space? Also - I do not understand enough about Windows notifications to understand if we could utilize SendMessage to initiate a custom draw.... It seems to me that you could specify an item and then invoke the DLL function to redraw the item that you specified with the colors that you specified.... That's the idea I get when I read the MSDN documentation on it: https://msdn.microsoft.com/en-us/library/windows/desktop/ff919573(v=vs.85).aspx Siao's Example modified for latest AutoIt: #Include <GuiConstantsEx.au3> #Include <GuiListView.au3> #include <WindowsConstants.au3> #cs ;custom draw constants Global Const $CDDS_ITEM = 0x10000 Global Const $CDDS_MAPPART = 0x5 Global Const $CDDS_POSTERASE = 0x4 Global Const $CDDS_POSTPAINT = 0x2 Global Const $CDDS_PREERASE = 0x3 Global Const $CDDS_PREPAINT = 0x1 Global Const $CDDS_SUBITEM = 0x20000 Global Const $CDDS_ITEMPOSTERASE = BitOR($CDDS_ITEM, $CDDS_POSTERASE) Global Const $CDDS_ITEMPOSTPAINT = BitOR($CDDS_ITEM, $CDDS_POSTPAINT) Global Const $CDDS_ITEMPREERASE = BitOR($CDDS_ITEM, $CDDS_PREERASE) Global Const $CDDS_ITEMPREPAINT = BitOR($CDDS_ITEM, $CDDS_PREPAINT) Global Const $CDIS_CHECKED = 0x8 Global Const $CDIS_DEFAULT = 0x20 Global Const $CDIS_DISABLED = 0x4 Global Const $CDIS_FOCUS = 0x10 Global Const $CDIS_GRAYED = 0x2 Global Const $CDIS_HOT = 0x40 Global Const $CDIS_INDETERMINATE = 0x100 Global Const $CDIS_MARKED = 0x80 Global Const $CDIS_SELECTED = 0x1 Global Const $CDIS_SHOWKEYBOARDCUES = 0x200 Global Const $CDRF_DODEFAULT = 0x0 Global Const $CDRF_NEWFONT = 0x2 Global Const $CDRF_NOTIFYITEMDRAW = 0x20 Global Const $CDRF_NOTIFYPOSTERASE = 0x40 Global Const $CDRF_NOTIFYPOSTPAINT = 0x10 Global Const $CDRF_NOTIFYSUBITEMDRAW = 0x20 Global Const $CDRF_SKIPDEFAULT = 0x4 #ce ;fonts for custom draw example ;bold Global $aFont1 = DLLCall("gdi32.dll","int","CreateFont", "int", 14, "int", 0, "int", 0, "int", 0, "int", 700, _ "dword", 0, "dword", 0, "dword", 0, "dword", 0, "dword", 0, "dword", 0, "dword", 0, _ "dword", 0, "str", "") ;italic Global $aFont2 = DLLCall("gdi32.dll","int","CreateFont", "int", 14, "int", 0, "int", 0, "int", 0, "int", 400, _ "dword", 1, "dword", 0, "dword", 0, "dword", 0, "dword", 0, "dword", 0, "dword", 0, _ "dword", 0, "str", "") $GUI = GUICreate("Listview Custom Draw", 400, 300) $cListView = GUICtrlCreateListView("", 2, 2, 394, 268, -1, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT)) $hListView = GUICtrlGetHandle($cListView) _GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100) _GUICtrlListView_InsertColumn($hListView, 1, "Column 2", 100) _GUICtrlListView_InsertColumn($hListView, 2, "Column 3", 100) ;
