EvilEd Posted November 11, 2008 Share Posted November 11, 2008 I have a feeling the answer is no, but I'm hopeful there is a workaround. Is there a workaround for the TreeView & ListView controls 260 character string limit? I know they store more than 260 characters, but they only display 260. I would rather have the TreeView working, but will settle for ListView. I have searched here and google without success. Thanks Ed Link to comment Share on other sites More sharing options...

EvilEd Posted November 12, 2008 Author Share Posted November 12, 2008 Thanks! Here is a sample: expandcollapse popup#Include <String.au3> #include <GuiTreeView.au3> #include <GuiConstantsEx.au3> #include <EditConstants.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) $GUI = GUICreate("Testing TreeView 260 char text display limit", 500, 420) GUISetOnEvent($GUI_EVENT_CLOSE, "dlgTabbedClose") ;$ListView = GUICtrlCreateListView("Results", 20, 100, 460, 220, $LVS_SORTASCENDING) ;$ListView = GUICtrlCreateListView("Results" & _StringRepeat(" ", 350), 20, 100, 460, 220, $LVS_SORTASCENDING) ;$ListView = _GUICtrlListView_Create($GUI, "Results", 20, 100, 460, 220) ;$hTreeView = GUICtrlCreateTreeView(20, 100, 460, 220, BitOR($TVS_EDITLABELS, $TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS, $TVS_CHECKBOXES), $WS_EX_CLIENTEDGE) $hTreeView = _GUICtrlTreeView_Create($GUI, 20, 100, 460, 100) $txtOutput = GUICtrlCreateEdit("Results", 20, 250, 460, 100, $ES_READONLY + $ES_MULTILINE + $ES_WANTRETURN + $ES_AUTOHSCROLL + $ES_AUTOVSCROLL + $WS_VSCROLL + $WS_HSCROLL) $btnExit = GUICtrlCreateButton("Exit", 20, 370, 60, 20) GUICtrlSetOnEvent(-1, "btnExitClick") GUISetState(@SW_SHOW, $GUI) Local $msg, $text $msg = _StringRepeat("1234567890", 25) & "abcdefghijklmnopqrstuvwxyz" $hItem = _GUICtrlTreeView_Add($hTreeView, 0, "TreeView can't display over 260 chars:") $TestItem = _GUICtrlTreeView_AddChild($hTreeView, $hItem, $msg) ;$TestItem = _GUICtrlTreeView_InsertItem($hTreeView, $msg, $hItem) $text = _GUICtrlTreeView_GetText($hTreeView, $TestItem) GUICtrlSetData($txtOutput, "But it does save the whole string:" & @CRLF & $text) _GUICtrlTreeView_SelectItem($hTreeView, $TestItem) While 1 = 1 Sleep(100) WEnd Exit Func btnExitClick() exit EndFunc Func dlgTabbedClose() exit EndFunc As far as I can tell, this is a Windows limit to the TreeView and ListView controls that AutoIt accesses.

rasim Posted November 12, 2008 Share Posted November 12, 2008 EvilEdSeems this is the visual/showing limit, because below code returns a correct length of the string:$text = _GUICtrlTreeView_GetText($hTreeView, $TestItem) MsgBox(0, "String Length", StringLen($text)) Link to comment Share on other sites More sharing options...
EvilEd Posted November 13, 2008 Author Share Posted November 13, 2008 EvilEd Seems this is the visual/showing limit, because below code returns a correct length of the string: $text = _GUICtrlTreeView_GetText($hTreeView, $TestItem) MsgBox(0, "String Length", StringLen($text)) Yes, that is correct. I'm sorry if I didn't explain it correctly, I thought I said that in my first message and made sure my example code points that out. I should have explained that the editbox under the treeview is actually reading the treeview control and has the full string past 260 chars. I'm hoping there is some way around this display limit. I'm thinking it will be confusing for people to view a string of 300 characters and only see 260 of it. As far as I can tell, it sounds like the limit is from Windows and not AutoIt3. I kinda doubt there is a way around this unless someone has written a similar control that doesn't rely on the Windows control. I hope I said that correctly... I'm pretty tired. I thank you for taking the time to look at it. Any help would be greatly appreciated. Ed Link to comment Share on other sites More sharing options...
