Here another approach to check if a script was already started using atoms and semaphores.
Atom:
#include <MsgBoxConstants.au3> Global $iSingleton = Singleton() If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!") EndIf MsgBox($MB_TOPMOST, "Singleton Test", "Singleton atom initialized: " & $iSingleton) Singleton_Delete($iSingleton) ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton ; Description ...: Checks if the script has been started already. ; Syntax ........: Singleton([$sOccurrenceName = @ScriptFullPath]) ; Parameters ....: $sOccurrenceName - [optional] a string value. Default is @ScriptFullPath. ; Return values .: If the function succeeds, the return value is the newly created atom or 0 else error is set and false is returned. ; Author ........: UEZ ; Modified ......: ; Remarks .......: If Singleton finds the atom it will return 0 and the atom token will be set to extended macro. It can be used to get the atom string using _WinAPI_AtomGlobalGetName. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globalfindatomw ; https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globaladdatomw ; Example .......: No ; =============================================================================================================================== Func Singleton($sOccurrenceName = @ScriptFullPath) Local $iFind = _WinAPI_AtomGlobalFind($sOccurrenceName) If @error Then Return SetError(1, 0, False) If $iFind Then Return SetExtended($iFind, 0) Local $iAtom = _WinAPI_AtomGlobalAdd($sOccurrenceName) If @error Then Return SetError(2, 0, False) Return $iAtom EndFunc ;==>Singleton ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton_Delete ; Description ...: Deletes the atom generated by the first started script. ; Syntax ........: Singleton_Delete($iAtom) ; Parameters ....: $iAtom - an integer value which was generated by Singleton ; Return values .: True if successful else false. ; Author ........: UEZ ; Modified ......: ; Remarks .......: Don't forget to call Singleton_Delete before first started script ends. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globaldeleteatom ; Example .......: No ; =============================================================================================================================== Func Singleton_Delete($iAtom) _WinAPI_AtomGlobalDelete($iAtom) If @error Then Return SetError(1, 0, False) Return True EndFunc ;==>Singleton_Delete ;internal functions Func _WinAPI_AtomGlobalFind($sAtomString) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalFindAtomW", "wstr", $sAtomString) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] EndFunc ;==>_WinAPI_AtomGlobalFind Func _WinAPI_AtomGlobalAdd($sAtomString) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalAddAtomW", "wstr", $sAtomString) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] EndFunc ;==>_WinAPI_AtomGlobalAdd Func _WinAPI_AtomGlobalDelete($nAtom) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalDeleteAtom", "short", $nAtom) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] = 0 EndFunc ;==>_WinAPI_AtomGlobalDelete Func _WinAPI_AtomGlobalGetName($nAtom, $iBufferSize = 512) Local $tBufferAtom = DllStructCreate("wchar name[" & $iBufferSize & "]") Local $aReturn = DllCall("kernel32.dll", "uint", "GlobalGetAtomNameW", "short", $nAtom, "struct*", $tBufferAtom, "int", $iBufferSize) If @error Or Not $aReturn[0] Then Return SetError(1, 0, -1) Return $tBufferAtom.name EndFunc ;==>_WinAPI_AtomGlobalGetName
Semaphore:
#include <MsgBoxConstants.au3> #include <WinAPIError.au3> Global $iSingleton = Singleton("&]8h/x87</htFV4-K*&.b.w~") If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!") EndIf MsgBox($MB_TOPMOST, "Singleton Test", "Singleton Semaphore initialized: " & $iSingleton) ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton ; Description ...: Checks if the script has been started already. ; Syntax ........: Singleton($sOccurrenceName) ; Parameters ....: $sOccurrenceName - a string value which will be used to create the semaphore handle. ; Return values .: True if Singleton started the first time. False if script was already started ; Author ........: UEZ ; Modified ......: ; Remarks .......: The system closes the handle automatically when the process terminates. The semaphore object is destroyed when its last handle has been closed. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-createsemaphorea ; Example .......: No ; =============================================================================================================================== Func Singleton($sOccurrenceName) If StringLen($sOccurrenceName) > 260 Then $sOccurrenceName = StringLeft($sOccurrenceName, 260) Local $aReturn = DllCall("kernel32.dll", "handle", "CreateSemaphoreA", "ptr", Null, "long", 0, "long", 1, "str", $sOccurrenceName) If @error Or Not $aReturn[0] Then Return SetError(1, 0, -1) Return SetExtended($aReturn[0], $aReturn[0] And _WinAPI_GetLastErrorMessage() = "The operation completed successfully.") EndFunc ;==>Singleton
Just start the script twice to see if it works.

Hi, first of all thanks to all the guys who always help people in the forums, I wouldn't be able to do anything if wasn't for your help, even if I don't ask it myself.
I've created this code to get some info on a monitoring network on my work. It relays on _IETableGetCollection and _IETableWriteToArray.
It works well, but take around 3:25 minutes to get the info from 28 pages (some of them are large and take longer to load, but most of them are small and fast).
My question is if you see a way to get the program to go faster...
I've tried to make it easy for you to understand and edited somethings with sensitive info.
(Some of the pages doesn't have the black divider with MIRA in the end, so I need to search if it is there or not.)
#include <IE.au3> #include <array.au3> Local $oIE = _IECreate("about:blank", 0, 0) Local $paginas[28] = [89, 90, 91, 92, 93, 96, 105, 113, 119, 125, 126, 129, 131, 133, 135, 137, 139, 140, 141, 144, 145, 146, 148, 149, 150, 151, 158, 159] Local $Datos_array[0][2] Local $oTable Local $tabla Local $aux_x = 1 Local $ar = 1 Local $Numtables_datos = 0 MsgBox(0, "asd", "asd") For $pag = 0 To UBound($paginas) - 1 Step 1 _IENavigate($oIE, "<WEBSITE URL>" & $paginas[$pag]) ; <<< the pages to load are always the same except for the last digits. _ArrayAdd($Datos_array, $paginas[$pag] & "|" & "Entrante", 0, "|") ; <<<<<<<<<<<<<<<< adds the page number toarray [0, 0] ;############################################ START counts amount of tables with traffic $oTable = _IETableGetCollection($oIE) Local $iNumTables = @extended For $i = 3 To $iNumTables - 2 Step 1 $oTable = _IETableGetCollection($oIE, $i) $nomb_tabla2 = _IETableWriteToArray($oTable) ; <<<<<<<< TABLE TO ARRAY. $string2 = StringStripWS($nomb_tabla2[1][0], 8) If $string2 <> "MIRA" Then $Numtables_datos = $Numtables_datos + 1 Next $tabla_End = $iNumTables - $Numtables_datos ;############################################ FIN $tabla_Start = 4 $tabla_trafico = 2 For $for = 1 To $Numtables_datos Step 1 $oTable = _IETableGetCollection($oIE, $tabla_Start - 1) ; <<<<<<<<<<< NAME OF THE TABLE; row2 = mira $nomb_tabla = _IETableWriteToArray($oTable) ; <<<<<<<< TABLE TO ARRAY ;########################################### ADDS the traffic number into the row $string = StringStripWS($nomb_tabla[1][0], 8) If $string == "MIRA" Then ;si o si pasa por aca 1 vez _ArrayAdd($Datos_array, $nomb_tabla[0][0]) $nomb_aux = $nomb_tabla[0][0] $aux_x = 1 $tabla_trafico = $tabla_trafico + 2 Else ;esto deberia ser por row _ArrayAdd($Datos_array, $nomb_aux & " " & $aux_x) $aux_x = $aux_x + 1 $tabla_trafico = $tabla_trafico + 1 EndIf $oTable = _IETableGetCollection($oIE, $tabla_trafico) Local $aTableData = _IETableWriteToArray($oTable) $bps = _ArrayToString($aTableData, "|", 0, 0, @CRLF, 0, 0) $bps = StringRight($bps, 5) $bps = StringLeft($bps, 4) $trafico_actual = _ArrayToString($aTableData, "|", 0, 0, @CRLF, 2, 2) If $bps == "Gbps" Then $trafico_actual = $trafico_actual * 1000 If $bps == "Kbps" Then $trafico_actual = $trafico_actual / 1000 $Datos_array[$ar][1] = $trafico_actual $ar = $ar + 1 If $string == "MIRA" Then $tabla_Start = $tabla_Start + 2 Else $tabla_Start = $tabla_Start + 1 EndIf Next $ar = $ar + 1 ;~ ############# CAÍDA ############ ;~ If $actual_entrante = 0 Then ;~ $xxx = 0 ;~ Do ;~ MsgBox(0, "Tráfico Caído", $paginas[$i], 5) ;~ $xxx = $xxx + 1 ;~ Until $xxx = 10 ;~ EndIf ;~ ############# CAÍDA ############.

I have a Word document containing a 9-column table where row 1 is the column headers. My goal is to read the table into a 2d array, remove some rows, update some fields, and add a few rows to the end. The resulting array will likely be a different length. Next, I want to write the data back into the table. If it's easier, I can write the data to a new document from a template containing the same table header with a blank 2nd row.
Here's my early attempt:
Local $oWord = _Word_Create() Local $oDoc = _Word_DocOpen($oWord, $sFile) Local $aData = _Word_DocTableRead($oDoc, 1) $aData[3][5] = "Something else" Local $oRange = _Word_DocRangeSet($oDoc, 0) $oRange = _Word_DocRangeSet($oDoc, $oRange, $wdCell, 9) _Word_DocTableWrite($oRange,$aData) This, unfortunately, writes the entire array into the first cell of row 2. What am I doing wrong?

hi dears, i have an question please if you can help me.
i maked an program to do some functions
and this program works with the global hot keys
i added an option to the users to change the hot keys
when i searched about how to do that i found this UDF
GUIHotkey.au3
http://www.autoitscript.com/forum/index.php?showtopic=107965
but the problem here that this UDF cant be detect the win key.
can you help me to add it, or if there are any others UDFSS wich do that work please give me some.
i hope that my question is clear for you.
thanks in advance

Hello,
I wrote a benchmark script to measure variable declarations
to find out whether you should focus more on static or global variables
#cs ---------------------------------------------------------------------------- AutoIt Version: 3.3.14.5 #ce ---------------------------------------------------------------------------- #Region Pre-Setting Local $iTally1 = 0 Local $iTally2 = 0 Local $iTally3 = 0 Local $iTally4 = 0 Local $iTally5 = 0 Local $iTally6 = 0 Local $iTally7 = 0 Global $GLOBALCONST1 = 1 Global $GLOBALCONST2 = 1 Global $GLOBALCONST3 = 1 Global $GLOBALCONST4 = 1 Global $GLOBALCONST5 = 1 #EndRegion Pre-Setting #Region Test Functions Func s1() Static $i = $GLOBALCONST1 Return $i EndFunc Func g2() Return $GLOBALCONST2 EndFunc Func g3() Static $i7 = "gsdgdfegbgbrwefw" Return $GLOBALCONST3 EndFunc Func g4() Static $i1 = 1 Static $i2 = "asd" Static $i3 = 234 Static $i4 = True Static $i5 = [0] Static $i6 = "hgsdg" Static $i7 = 1 Static $i8 = 1 Static $i9 = 1 Static $i0 = 1 Return $GLOBALCONST4 EndFunc Func g5() Local $i = $GLOBALCONST5 Return $i EndFunc Func g6() Local $i = 1 Return $i EndFunc Func g7() Return 1 EndFunc #EndRegion Test Functions #Region Benchmark Loop For $i = 0 To 15 Local $tDelta = TimerInit() Do $iTally1 += s1() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally2 += g2() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally3 += g3() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally4 += g4() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally5 += g5() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally6 += g6() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally7 += g7() Until TimerDiff($tDelta) >= 1000 Next #EndRegion Benchmark Loop ConsoleWrite(@CRLF&"Static1: "&$iTally1&" pkt"&@CRLF&"Global2: "&$iTally2&" pkt"&@CRLF&"Global3: "&$iTally3&" pkt"&@CRLF&"Global4: "&$iTally4&" pkt"&@CRLF&"Local5: "&$iTally5&" pkt"&@CRLF&"Local6: "&$iTally6&" pkt"&@CRLF&"Hardcode7:"&$iTally7&" pkt"&@CRLF) #cs Result Static1: 10291881 pkt global to static Global2: 13977324 pkt only global Global3: 9886169 pkt global and static Global4: 2933051 pkt global and many statics Local5: 9937314 pkt global to local Local6: 10306484 pkt only local Hardcode7: 14835319 pkt no variable #ce Result:
100% no variable, hardcore value
94% only global variable use
69% only local variable use with hardcore value set
69% only static variable use with global variable value set
67% declaration of local variable with global variable value set
66% only global variable use with one static variable beside
20% only global variable use with ten static variables beside
My thesis of the result:
Be careful with declarations, whether local, global or static Note: in my test the global variable performance was better than the local one, but in practice the global one would lose performance due to multiple operations
What is your best practice sharing data between multiple functions?
