My comments are not directed at you JScript.My first post gives additional reasons of support for your method. Your UDF fixes two problems with the EM_SETCUEBANNER method for users with requirement for Asian languages support that is missing in XP, as well as the broken cue banner when the control has focus option.

Edit: My apologies JScript and James for my incorrect assumption and off-topic remark to the post above.

You seem to have also missed the lower half of this post.

Russian is included in lack of Asian language support in XP

Hi AZJIO Two reasons for using JScripts alternative to native EM_SETCUEBANNER in XP 1/ I forgot to mention XP has an issue with Asian Language support that was not fixed until Vista. Microsoft could not be bothered to fix it in any of the XP service packs of course... Sorting it all Out : EM_SETCUEBANNER vs. international support in XP and Server 2003 https://blogs.msdn.com/michkap/archive/2006/02/25/538735.aspx 2/ Display cuebanner when edit has focus feature does not work in XP. EM_SETCUEBANNER Message, wParam TRUE - not working for XP. - MSDN Forums http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2799112&SiteID=1

A novel approach JScript Also gets around the XP compatibility issues of EM_SETCUEBANNER @AZJIO Minimum OS for EM_SETCUEBANNER is XP Regarding any other posts of EM_SETCUEBANNER, a simple forum check for pre-existing examples would have sufficed, but that is done so infrequently here...

Thanks UEZ Nice pure math trackbar in GDI+! Any idea on code to use alpha transparent images for the trackbar thumb? Rounded thumb png's?

_GUICtrlListView_SetItemChecked is faster than _GUICtrlTreeView_SetChecked, even after both are optimized.

Your slowdown would be from the large number of thumbnails. If you are not already doing so, use the BeginUpdate/EndUpdate functions before and after calling SetItemChecked and use the extended style LVS_EX_DOUBLEBUFFER. (just a paint buffer that helps with flickering, especially with customdrawn listviews and graphics painting, wont help with your issue) Maybe move to a virtual (ownerdata) listview - only draws the number of items that fit in the listview client area. Uses the WM_NOTIFY LVN_GETDISPINFOW notification to update the items shown as the listview is scrolled. That way you only load thumbnails on demand, and only as many as are visible or use a cache of images in an array so each full page scroll is not having to load all the images for a page at once. I think there are examples of this on the forum. I coded an example loading thumbnails to an array, just to try it, but the memory use was high. This optimized version of _GUICtrlListView_SetItemChecked halves the time to check all items. Modified for listview control ID only The example is slower creating the items with the unmodified udf _GUICtrlListView_AddItem/AddSubItem functions than it is with the native GUICtrlCreateListViewItem Edit: added Begin/EndUpdate functions #include <GUIConstantsEx.au3> #include <GuiListView.au3> _Main() Func _Main() Local $exStyles = BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES), $cListView GUICreate("ListView Set Item Checked State", 400, 300) $cListView = GUICtrlCreateListView("", 2, 2, 394, 268) _GUICtrlListView_SetExtendedListViewStyle($cListView, $exStyles) GUISetState() _GUICtrlListView_BeginUpdate($cListView) _GUICtrlListView_AddColumn($cListView, "Column 1", 100) _GUICtrlListView_AddColumn($cListView, "Column 2", 100) _GUICtrlListView_AddColumn($cListView, "Column 3", 100) Local $iIdx ConsoleWrite("+ Creating 5000 items " & @LF) ; Add items For $i = 0 To 5000 $iIdx = _GUICtrlListView_AddItem($cListView, "Row 1: Col 1", 0) _GUICtrlListView_AddSubItem($cListView, $iIdx, "Row 1: Col 2", 1) _GUICtrlListView_AddSubItem($cListView, $iIdx, "Row 1: Col 3", 2) Next _GUICtrlListView_EndUpdate($cListView) _GUICtrlListView_BeginUpdate($cListView) ConsoleWrite("+ Check all items " & @LF) Local $iT = TimerInit() __GUICtrlListView_SetItemChecked($cListView, -1, True) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : TimerDiff($iT) = ' & TimerDiff($iT) & @crlf) _GUICtrlListView_EndUpdate($cListView) Do Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete() EndFunc ;==>_Main ;modified for GUICtrlCreateListView() control ID only Func __GUICtrlListView_SetItemChecked($cLV, $iIndex, $fCheck = True) Local $pItem, $tItem, $iState = 0x1000 $tItem = DllStructCreate($tagLVITEM) $pItem = DllStructGetPtr($tItem) DllStructSetData($tItem, "Mask", $LVIF_STATE) DllStructSetData($tItem, "StateMask", $LVIS_STATEIMAGEMASK) If @error Then Return SetError($LV_ERR, $LV_ERR, $LV_ERR) If ($fCheck) Then $iState = 0x2000 Local $hLV = GUICtrlGetHandle($cLV) If $iIndex <> -1 Then ;check single item DllStructSetData($tItem, "Item", $iIndex) DllStructSetData($tItem, "State", $iState) Return GUICtrlSendMsg($cLV, $LVM_SETITEMW, 0, $pItem) <> 0 Else ;check all For $x = 0 To _GUICtrlListView_GetItemCount($cLV) - 1 DllStructSetData($tItem, "Item", $x) DllStructSetData($tItem, "State", $iState) ;_SendMessage($cLV, $LVM_SETITEMW, 0, $tItem, 0, "wparam", "struct*") If Not GUICtrlSendMsg($cLV, $LVM_SETITEMW, 0, $pItem) <> 0 Then Return SetError($LV_ERR, $LV_ERR, $LV_ERR) EndIf Next Return True EndIf Return False EndFunc ;==>__GUICtrlListView_SetItemChecked

Trackbars (Slider) can be custom skinned by Customdrawing or Ownerdrawing. I've used a skinning dll in the past to theme a slider in a script, otherwise I haven't the need to bother working out the details of customdrawing a slider. Yashied posted an example of painting the background image behind a slider that used customdrawing. At the time, I did a few tests theming the slider, then left it. Here is the updated code modified from Yashied's post with hard coded metrics, no image alpha transparency support and without image state code (hot/focused/disabled). Version with background image has high cpu usage when trackbar moved (NM_CUSTOMDRAW message) and some optimization is needed. Alternately use a layered gui for transparency. Or use UEZ's custom trackbar posted in your other thread just as I was logging in to post this.

@2Reg2Post The OP is only running selected programs (exe) from the treeview, and most likely not in the thousands. Using a listview was suggested by me in a previous thread by the OP. Yes, a listview check all with _GUICtrlListView_SetItemChecked $iIndex = -1 (internal ForNext loop) is faster than a treeview, and 2x faster if _GUICtrlListView_SetItemChecked is optimized. Unfortunately there is no listview/treeview single message to select all checkboxes without having to loop through all items. A few thousand treeview items do not take several minutes to check. Checking 5000 items with _GUICtrlTreeView_SetChecked $iIndex = -1 takes approx 5 seconds, and that can be halved with optimization. Both the treeview and listview functions can be optimized by using only the listview control ID* and removing the unicode, external process and handle/control ID checks. *_SendMessage() with a handle is 4 times slower than GuiSendMsg() with a control ID. ;optimized check all Func _TVCheckAll($hWnd, $fCheck = True) ;coded by rover 2k12 If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd) If Not IsHWnd($hWnd) Then Return SetError(1, 0, False) Local $hItem = _GUICtrlTreeView_GetFirstItem($hWnd), $iChk = 0 _GUICtrlTreeView_BeginUpdate($hWnd) ;~ Do ;~ If _GUICtrlTreeView_SetChecked($hWnd, $hItem, $fCheck) Then $iChk += 1 ;~ $hItem = _GUICtrlTreeView_GetNextSibling($hWnd, $hItem) ;~ Until $hItem = 0 Local $tItem = DllStructCreate($tagTVITEMEX) DllStructSetData($tItem, "Mask", $TVIF_STATE) DllStructSetData($tItem, "StateMask", 0xf000) If ($fCheck) Then DllStructSetData($tItem, "State", 0x2000) Else DllStructSetData($tItem, "State", 0x1000) EndIf Do DllStructSetData($tItem, "hItem", $hItem) If _SendMessage($hWnd, $TVM_SETITEMW, 0, $tItem, 0, "wparam", "struct*") Then $iChk += 1 $hItem = _SendMessage($hWnd, $TVM_GETNEXTITEM, $TVGN_NEXT, $hItem, 0, "wparam", "handle", "handle") Until $hItem = 0 _GUICtrlTreeView_EndUpdate($hWnd) Return SetError(0, $iChk, True) EndFunc ;==>_TVCheckAll

You still have the memory leak from undeleted child item control ids if you use TVM_DELETEITEM. Might I suggest purging the message queue after all delete item events. In my DeleteAll function there were no misfires (only tested on my XP box - 7x64 box being rebuilt) Setting events for items of a Treeview as if they are controls obviously has issues with false events when items are unregistered/deleted. Treeview/Listview Item notifications should be processed in a WM_NOTIFY message handler... Consider the added complication of having to code delete functions to loop through and unregister (item set to run an event mode function) and delete every root and child item. and then clear the message queue, as opposed to using the existing udf single line delete all or delete all children functions with WM_NOTIFY for event handling. What problems are you having using the udf functions? I forgot that _GUICtrlTreeView_GetItemParam returns False instead of 0 when there is no item data (the combobox and listview param functions return 0 for no data). Try this message queue purge example, no memory leaks and no event misfires.
