Hello Melba23, thanks again for the great help. I've tried adding a function to delete an item from the list, but unfortunately it doesn't work the way it is supposed to. As I am an AutoIt beginner I've added some comments for myself to clarify what is going on in the script, so sorry if it got a bit longer Have a look at my Delete_item function: if I try deleting items from the end of the list it seems to work, but if I start somewhere in the middle it results in some mess I guess I don't get the point of the $hStart_ID dummy, maybe you can explain it in short? As far as I understand the overall number of items in the list is kept in $aList_Array[0] as an integer. But how does GUICtrlRead($hListView) - $hStart_ID relate to the current position ($hStart_ID seems to equal 8 all the time)? #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <GUIListView.au3> #include <Array.au3> Global $aList_Array[1] ; Fill the array with some test data For $i = 1 To 5 _ArrayAdd($aList_Array, $i & "-----" & $i & "-----" & $i) $aList_Array[0] += 1 ConsoleWrite ( "array elements " & $aList_Array[$i] &@CRLF) ; ==> the first item in the array holds information on the overall item count (eg. a $aList_Array[0]=23 means there are 23 items in the list after the for loop) Next ConsoleWrite ( "array counter " & $aList_Array[0] &@CRLF) ; Create dialog Local $hList_Win = GUICreate("UP/Down ListView", 500, 500, Default, Default, BitOr($WS_POPUPWINDOW, $WS_CAPTION)) ; $WS_POPUPWINDOW > enables the WS_BORDER, WS_POPUP, and WS_SYSMENU styles ; $WS_CAPTION > window has a title bar GUISetBkColor(0xCECECE) ; Create list box with no col headers and permit only 1 selection Local $hListView = GUICtrlCreateListView ("_", 10, 10, 480, 390, $LVS_NOCOLUMNHEADER + $LVS_SINGLESEL, $LVS_EX_FULLROWSELECT ) ; Set up alt line colouring GUICtrlSetBkColor(-1, $GUI_BKCOLOR_LV_ALTERNATE) ; Set col width _GUICtrlListView_SetColumnWidth(-1, 0, $LVSCW_AUTOSIZE_USEHEADER) ; Create buttons Local $delete_item_Button = GUICtrlCreateButton("Delete Item", 170, 410, 80, 30) Local $hList_Move_Up_Button = GUICtrlCreateButton("Move Up", 270, 410, 80, 30) Local $hList_Move_Down_Button = GUICtrlCreateButton("Move Down", 270, 450, 80, 30) Local $hList_Cancel_Button = GUICtrlCreateButton("Cancel", 370, 410, 80, 30) ; Fill listbox, list handles indexed on this dummy Local $hStart_ID = GUICtrlCreateDummy() ConsoleWrite ("hStart_ID is " &$hStart_ID &@CRLF ) ; Fill listbox ; Add placeholders for the list items For $i = 1 To $aList_Array[0] GUICtrlCreateListViewItem($aList_Array[$i], $hListView) GUICtrlSetBkColor(-1, 0xCCFFCC) Next ; Show dialog GUISetState(@SW_SHOW, $hList_Win) While 1 Local $aMsg = GUIGetMsg(1) ;==> in the MessageLoop mode the (1) param returns an array, where $aMsg[0] contains the event ;and $aMsg[1] the window handle.

Great! Thanks a lot - it worked :-) Still have to learn a lot. I only had to put the two "Show" & "Hide" lines in the right order like this: GUICtrlSetState($$help_me_H,$GUI_SHOW ) Else GUICtrlSetState($$help_me_H, $GUI_HIDE) Ohterwise the control item got hidden when the checkbox was checked Thanks again!

Hi everybody! I am new to AutoIt but I have some Java programming background so I was able to figure a lot of stuff on my own. But this time I am really stuck muttley my script is running in "GUIOnEventMode". What I want to do is: if one activates a checkbox the GUI shall display another control next to it, lets say an image. If on the other hand the checkbox is being unckecked the GUI shall set the visibility of the control to "false". The question is: is it possible to query the GUI constantly in "GUIOnEventMode"? Here is an example code, just some snippets: $H = GUICtrlCreateCheckbox("Higlight Mode", 54, 384, 97, 25) GUICtrlSetOnEvent(-1, "showHelp_H") ;------ Function ------- Func showHelp_H() If $H = $GUI_CHECKED Then GUICtrlSetState($help_me_H,$GUI_SHOW) ; $help_me_H is an image declared on some other place in the script ElseIf $H = $GUI_UNCHECKED Then GUICtrlSetState($help_me_H,$GUI_HIDE) EndIf EndFunc Thanks a lot !
