Today I read this : https://stackoverflow.com/questions/3883129/extract-tortoisesvn-saved-password And also read a little about: Windows Data Protection API also: https://en.wikipedia.org/wiki/Data_Protection_API and: it seams that also browsers uses DPAPI Did you hit this API before ?

Not. Thanks this is what I was looking for.

I have a problem. The selected item/row in the listview changes color after clicking another item in the window and is often almost invisible - especially on older monitors or in unfavorable lighting, not to mention for users with poor eyesight. Therefore, I'd like to be able to specify the color of an item that is selected but not focused. For example, using the example GUICtrlCreateListView.au3 from HelpFile ; == Example 2 ; Coloring Groups #include <ColorConstants.au3> #include <GUIConstantsEx.au3> #include <GuiImageList.au3> #include <GuiListView.au3> #include <WinAPIGdi.au3> #include <WinAPIGdiDC.au3> #include <WinAPIHObj.au3> Global $g_hGUI = 0, $g_hListView = 00 Example() Func Example() ; create GUI window $g_hGUI = GUICreate("Example") ; create ListView control Local $idListview = GUICtrlCreateListView("", 10, 10, 350, 200) $g_hListView = ControlGetHandle($g_hGUI, '', $idListview) Local $idButton = GUICtrlCreateButton("Test", 10, 220, 70, 20) ; Enable extended control styles _GUICtrlListView_SetExtendedListViewStyle($idListview, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_SUBITEMIMAGES)) GUISetState(@SW_SHOW) ; Set ANSI format ;~ _GUICtrlListView_SetUnicodeFormat($idListview, False) GUIRegisterMsg($WM_NOTIFY, WM_NOTIFY) ; Load images Local $hImage = _GUIImageList_Create() _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($idListview, $COLOR_RED, 16, 16)) _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($idListview, $COLOR_GREEN, 16, 16)) _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($idListview, $COLOR_BLUE, 16, 16)) _GUICtrlListView_SetImageList($idListview, $hImage, 1) ; Add columns _GUICtrlListView_AddColumn($idListview, "Column 1", 100) _GUICtrlListView_AddColumn($idListview, "Column 2", 100) _GUICtrlListView_AddColumn($idListview, "Column 3", 142) ; Add items _GUICtrlListView_AddItem($idListview, "Row 1: Col 1", 0) _GUICtrlListView_AddSubItem($idListview, 0, "Row 1: Col 2", 1, 1) _GUICtrlListView_AddSubItem($idListview, 0, "Row 1: Col 3", 2, 2) _GUICtrlListView_AddItem($idListview, "Row 2: Col 1", 1) _GUICtrlListView_AddSubItem($idListview, 1, "Row 2: Col 2", 1, 2) _GUICtrlListView_AddItem($idListview, "Row 3: Col 1", 2) ; Build groups _GUICtrlListView_EnableGroupView($idListview) _GUICtrlListView_InsertGroup($idListview, -1, 1, "Group 1") _GUICtrlListView_InsertGroup($idListview, -1, 2, "Group 2") _GUICtrlListView_SetItemGroupID($idListview, 0, 1) _GUICtrlListView_SetItemGroupID($idListview, 1, 2) _GUICtrlListView_SetItemGroupID($idListview, 2, 2) ; Loop until the user exits.

I know this is old topic. I didn't answer here. I'm asking if anyone knows if this is related. I know that even if it were related, a lot of time has passed and an update would be needed. I also consider that I'll have to handle the update myself. For now, I'm simply looking for various solutions related to Spell Checking itself. I'm looking for the most suitable option. I am currently waiting for a solution that @Nine may create or not in this thread: I hope so. However, being cautious, I also asked the question here to see if anyone else is using the solution created by @iCode. So I hope you won't close this thread

I was in hope that my links were good. Finally I found this file on my disc as I had this file: c:\Program Files (x86)\Windows Kits\10\Include\10.0.26100.0\um\spellcheck.h but @ioa747 was faster than me.

Is this related to: https://github.com/hunspell/hunspell/releases ?

btw. It is little funny (as I did many COM stuff in AutoIt) but .... I'm not familiar with ObjCreateInterface() and for this reason at first I also asked ChatGPT for example: #include <MsgBoxConstants.au3> ; === COM interface GUIDs (global constants) === Global Const $CLSID_SpellCheckerFactory = "{7AB36653-1796-484B-BDFA-E74F1DB7C1DC}" Global Const $IID_ISpellCheckerFactory = "{8E018A9D-2415-4677-BF08-794EA61F94BB}" Global Const $IID_ISpellChecker = "{B6FD0B71-E2BC-4653-8D05-F197E0D3B83B}" ; === Interface definitions (global tags) === Global Const $TAG_ISpellCheckerFactory = _ "CreateSpellChecker hresult(wstr;ptr*);" & _ ; Create spell checker for language "get_SupportedLanguages hresult(ptr*);" ; Get supported languages Global Const $TAG_ISpellChecker = _ "Check hresult(wstr;ptr*);" & _ ; Check text for spelling errors "Suggest hresult(wstr;ptr*);" ; Get suggestions ; === Example entry point === _EXAMPLE() Func _EXAMPLE() ; Create SpellCheckerFactory COM object Local $oFactory = ObjCreateInterface( _ $CLSID_SpellCheckerFactory, _ $IID_ISpellCheckerFactory, _ $TAG_ISpellCheckerFactory) If @error Then MsgBox($MB_ICONERROR, "Error", "Failed to create SpellCheckerFactory") Return EndIf ; Create spell checker for Polish language Local $pSpellChecker = 0 $oFactory.CreateSpellChecker("pl-PL", $pSpellChecker) If $pSpellChecker = 0 Then MsgBox($MB_ICONERROR, "Error", "Failed to create SpellChecker for pl-PL") Return EndIf ; Bind ISpellChecker interface Local $oSpell = ObjCreateInterface($pSpellChecker, $IID_ISpellChecker, $TAG_ISpellChecker) If @error Then MsgBox($MB_ICONERROR, "Error", "Failed to bind ISpellChecker interface") Return EndIf ; Word to test Local $sWord = "ksionszka" ; Perform spell check Local $pErrors = 0 $oSpell.Check($sWord, $pErrors) ; NOTE: This is simplified logic! ; Proper implementation should enumerate IEnumSpellingError If $pErrors = 0 Then MsgBox($MB_ICONINFORMATION, "Result", "Word is correct: " & $sWord) Else MsgBox($MB_ICONWARNING, "Result", "Word is INCORRECT: " & $sWord) EndIf EndFunc ;==>_EXAMPLE of course not works well.

I saw here on the forum few different ways of checking spell: Spell Checker (by iCode) OpenOffice/LibreOffice Spell Checker (by GMK) v0.1.1 Scite4AutoIt SpellChecker using LibreOffice even few topics about spell checking with Word. Custom Spell Checker But I start wondering how Notepad in Windows 11 finds out that some words are written incorrectly. Then I ask ChatGPT about and he point me to Spell Checking API. https://learn.microsoft.com/en-us/windows/win32/intl/about-the-spell-checker-api So here is my question: Has anyone worked in AutoIt with MS Windows Spell Checking API ?
