it recomended to use the builten function
_DateDiff
hello autoit team
i made a simple function to help me get the difference between to date
i liked to share it with you
the paramatrs of this function
is firstdate and lastedate
the two params is as the following
year/month/day hours:minuts:seconds
here is the function
#include <date.au3> func _dateBetween($s_firstDate, $s_lastDate = default) if not (StringRegExp($s_firstDate, "((\d{4})\/(\d{2})\/(\d{2})\s(\d{2})\:(\d{2})\:(\d{2}))", 0) = 1) then Return SetError(1, 0, 0) if $s_lastDate = default then $s_lastDate = @year & "/" & @mon & "/" & @mday & " " & @hour & ":" & @min & ":" & @sec if not (StringRegExp($s_lastDate, "((\d{4})\/(\d{2})\/(\d{2})\s(\d{2})\:(\d{2})\:(\d{2}))", 0) = 1) then Return SetError(2, 0, 0) local $a_FirstSplitDate = StringSplit(StringRegExpReplace($s_firstDate, "((.*)\s(.*))", "$2"), "/", 2) local $a_FirstSplitTime = StringSplit(StringRegExpReplace($s_firstDate, "((.*)\s(.*))", "$3"), ":", 2) local $a_lastSplitDate = StringSplit(StringRegExpReplace($s_lastDate, "((.*)\s(.*))", "$2"), "/", 2) local $a_LastSplitTime = StringSplit(StringRegExpReplace($s_lastDate, "((.*)\s(.*))", "$3"), ":", 2) local $i_firstDateValue = _DateToDayValue($a_FirstSplitDate[0], $a_FirstSplitDate[1], $a_FirstSplitDate[2]) local $i_LastDateValue = _DateToDayValue($a_LastSplitDate[0], $a_LastSplitDate[1], $a_LastSplitDate[2]) if $i_firstDateValue > $i_LastDateValue then Return SetError(3, 0, 0) local $i_totalDays = $i_LastDateValue-$i_firstDateValue if not ($i_totalDays = 0) then if $a_FirstSplitTime[0] <= $a_lastSplitTime[0] then $i_totalDays += 1 $a_lastSplitTime[0] -= $a_FirstSplitTime[0] elseIf $a_FirstSplitTime[0] > $a_lastSplitTime[0] then if $i_totalDays > 0 then $i_totalDays -= 1 $a_FirstSplitTime[0] -= $a_lastSplitTime[0] endIf endIf endIf local $i_totalYears = 0 if $i_totalDays >= 365 then While $i_totalDays >= 365 $i_totalYears += 1 $i_totalDays -= 365 Wend endIf local $i_TotalMonths = 0 if $i_totalDays >= 30 then While $i_totalDays >= 30 $i_totalMonths += 1 $i_totalDays -= 30 Wend endIf local $i_totalWeeks = 0 if $i_totalDays >= 7 then While $i_totalDays >= 7 $i_totalWeeks += 1 $i_totalDays -= 7 Wend endIf $i_totalSeconds = ((($a_FirstSplitTime[0]*60)*60)+($a_FirstSplitTime[1]*60)+($a_FirstSplitTime[2]))-((($a_lastSplitTime[0]*60)*60)+($a_lastSplitTime[1]*60)+($a_LastSplitTime[2])) local $minus = "" if $i_totalSeconds < 0 then $minus = "-" $i_totalSeconds = StringReplace($i_totalSeconds, "-", "") endIf local $i_totalHours = 0 if $i_totalSeconds >= 3600 then While $i_totalSeconds >= 3600 $i_totalHours += 1 $i_totalSeconds -= 3600 Wend endIf local $i_totalminuts = 0 if $i_totalSeconds >= 60 then While $i_totalSeconds >= 60 $i_totalminuts += 1 $i_totalSeconds -= 60 Wend endIf local $a_arrayReturn[7] $a_arrayReturn[0] = $i_totalYears $a_arrayReturn[1] = $i_totalMonths $a_arrayReturn[2] = $i_totalWeeks $a_arrayReturn[3] = $i_totalDays $a_arrayReturn[4] = $minus & $i_totalHours $a_arrayReturn[5] = $minus & $i_totalminuts $a_arrayReturn[6] = $minus & $i_totalSeconds return $a_arrayReturn endFunc
here is an example
$a_calc = _dateBetween("2015/02/12 23:00:05", "2030/02/12 23:25:50") msgBox(64, "result", StringFormat("the difference is : %i years and %i months and %i weeks and %i days and %i hours and %i minuts and %i seconds", $a_calc[0], $a_calc[1], $a_calc[2], $a_calc[3], $a_calc[4], $a_calc[5], $a_calc[6]))
am waiting for your comments
with my greetings

Hi everyone,
I am bit stumped as to why I am not able to set the time in the Date control
#include <DateTimeConstants.au3> #include <GUIConstantsEx.au3> #include <MsgBoxConstants.au3> Example() Func Example() GUICreate("My GUI get date", 200, 200, 800, 200) Local $idDate = GUICtrlCreateDate("1953/04/25", 10, 10, 185, 20, $DTS_TIMEFORMAT) ; to select a specific default format Local $sStyle = "HH:mm:ss" GUICtrlSendMsg($idDate, $DTM_SETFORMATW, 0, $sStyle) ; Set time Local $iRet = GUICtrlSetData($idDate, '13:33:37') ConsoleWrite('GUICtrlSetData returned ' & ($iRet = 1 ? 'success' : 'failure') & @CRLF) GUISetState(@SW_SHOW) ; Loop until the user exits. While GUIGetMsg() <> $GUI_EVENT_CLOSE WEnd MsgBox($MB_SYSTEMMODAL, "Time", GUICtrlRead($idDate)) EndFunc ;==>Example The documentation for GUICtrlSetData clearly mentions that it uses the same format as GUICtrlRead:
But I get failure
What gives?
Thanks for the help in advance!

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.
The disadvantage of using atoms is that atoms have a memory that means when your app is crashing or you forgot to delete the atom then the atom does still have the $sOccurrenceName saved and thus Singleton will not work if you use the same same value for $sOccurrenceName.
With semaphore you don't have this issue.
Thanks to jj2007 and SARG.
