jchapman15 Posted June 14, 2013 Posted June 14, 2013 Can anyone tell me why a window handle becomes invalid after it's stored inside a dictionary? If you disable the line where it's stored the RichEdit box will show, otherwise it _GUICtrlRichEdit_Create errors out -1 (window handle no longer exists) #include <GuiRichEdit.au3> #include <WindowsConstants.au3> $controls = ObjCreate("Scripting.Dictionary") $win = GUICreate("Enter Information", 400, 400) $controls.Add("gui", $win) ;if window handle stored in a dictionary object then the handle is invalidated _GUICtrlRichEdit_Create($win, "test string", 25, 200, 350, 100, BitOr($ES_AUTOHSCROLL, $ES_AUTOVSCROLL, $WS_VSCROLL, $ES_MULTILINE, $ES_READONLY)) GUISetState() While GUIGetMsg() <> -3 sleep(10) WEnd

jchapman15 Posted June 14, 2013 Author Posted June 14, 2013 (edited) Water: Well I didn't really need to do it that way I could store the window handle in a global, but the dictionary keeps all of my control IDs on the GUI in a nice organized package that can be easily passed to multiple functions. NutStomper: Odd that it converts the original variable, dictionary.Add is ByRef then I guess? Thanks for the workaround! Edited June 14, 2013 by jchapman15
water Posted June 14, 2013 Posted June 14, 2013 I usually use an array to store all the IDs of a GUI. Advantage: No external references needed. Disadvantage: You can't access the elements by name.

jchapman15 Posted June 14, 2013 Author Posted June 14, 2013 I used arrays to start, but after my GUI became pretty complex my code started to become too much of a pain to update having to look back and forth to figure out which indexes match to which controls. Not having to worry about external references is a definate plus, but portability isn't a concern with this project. Thanks for your help!
guinness Posted June 15, 2013 Posted June 15, 2013 The handle is being converted to a number when it's added to the dictionary. Use HWnd() to convert it back to a handle. And you can use Ptr. #include <Constants.au3> Local $hGUI = GUICreate(Default) MsgBox($MB_SYSTEMMODAL, '', 'hGUI = ' & $hGUI) MsgBox($MB_SYSTEMMODAL, '', 'hGUI = ' & Number($hGUI)) MsgBox($MB_SYSTEMMODAL, '', 'Number-Ptr = ' & Ptr(Number($hGUI)) & @CRLF & 'Number-HWnd = ' & HWnd(Number($hGUI))) UDF List: _AdapterConnections() • _AlwaysRun() • _AppMon() • _AppMonEx() • _ArrayFilter/_ArrayReduce • _BinaryBin() • _CheckMsgBox() • _CmdLineRaw() • _ContextMenu() • _ConvertLHWebColor()/_ConvertSHWebColor() • _DesktopDimensions() • _DisplayPassword() • _DotNet_Load()/_DotNet_Unload() • _Fibonacci() • _FileCompare() • _FileCompareContents() • _FileNameByHandle() • _FilePrefix/SRE() • _FindInFile() • _GetBackgroundColor()/_SetBackgroundColor() • _GetConrolID() • _GetCtrlClass() • _GetDirectoryFormat() • _GetDriveMediaType() • _GetFilename()/_GetFilenameExt() • _GetHardwareID() • _GetIP() • _GetIP_Country() • _GetOSLanguage() • _GetSavedSource() • _GetStringSize() • _GetSystemPaths() • _GetURLImage() • _GIFImage() • _GoogleWeather() • _GUICtrlCreateGroup() • _GUICtrlListBox_CreateArray() • _GUICtrlListView_CreateArray() • _GUICtrlListView_SaveCSV() • _GUICtrlListView_SaveHTML() • _GUICtrlListView_SaveTxt() • _GUICtrlListView_SaveXML() • _GUICtrlMenu_Recent() • _GUICtrlMenu_SetItemImage() • _GUICtrlTreeView_CreateArray() • _GUIDisable() • _GUIImageList_SetIconFromHandle() • _GUIRegisterMsg() • _GUISetIcon() • _Icon_Clear()/_Icon_Set() • _IdleTime() • _InetGet() • _InetGetGUI() • _InetGetProgress() • _IPDetails() • _IsFileOlder() • _IsGUID() • _IsHex() • _IsPalindrome() • _IsRegKey() • _IsStringRegExp() • _IsSystemDrive() • _IsUPX() • _IsValidType() • _IsWebColor() • _Language() • _Log() • _MicrosoftInternetConnectivity() • _MSDNDataType() • _PathFull/GetRelative/Split() • _PathSplitEx() • _PrintFromArray() • _ProgressSetMarquee() • _ReDim() • _RockPaperScissors()/_RockPaperScissorsLizardSpock() • _ScrollingCredits • _SelfDelete() • _SelfRename() • _SelfUpdate() • _SendTo() • _ShellAll() • _ShellFile() • _ShellFolder() • _SingletonHWID() • _SingletonPID() • _Startup() • _StringCompact() • _StringIsValid() • _StringRegExpMetaCharacters() • _StringReplaceWholeWord() • _StringStripChars() • _Temperature() • _TrialPeriod() • _UKToUSDate()/_USToUKDate() • _WinAPI_Create_CTL_CODE() • _WinAPI_CreateGUID() • _WMIDateStringToDate()/_DateToWMIDateString() • Au3 script parsing • AutoIt Search • AutoIt3 Portable • AutoIt3WrapperToPragma • AutoItWinGetTitle()/AutoItWinSetTitle() • Coding • DirToHTML5 • FileInstallr • FileReadLastChars() • GeoIP database • GUI - Only Close Button • GUI Examples • GUICtrlDeleteImage() • GUICtrlGetBkColor() • GUICtrlGetStyle() • GUIEvents • GUIGetBkColor() • Int_Parse() & Int_TryParse() • IsISBN() • LockFile() • Mapping CtrlIDs • OOP in AutoIt • ParseHeadersToSciTE() • PasswordValid • PasteBin • Posts Per Day • PreExpand • Protect Globals • Queue() • Resource Update • ResourcesEx • SciTE Jump • Settings INI • SHELLHOOK • Shunting-Yard • Signature Creator • Stack() • Stopwatch() • StringAddLF()/StringStripLF() • StringEOLToCRLF() • VSCROLL • WM_COPYDATA • More Examples...
