[Solved] Calculate/Compare Functions speed ?

Hey 

I've these two functions to do a base64 conversation , Is there any way to compare the exact speed of both of them ?

Func _Base64Encode($input)

    $input = Binary($input)

    Local $struct = DllStructCreate("byte[" & BinaryLen($input) & "]")

    DllStructSetData($struct, 1, $input)

    Local $strc = DllStructCreate("int")

    Local $a_Call = DllCall("Crypt32.dll", "int", "CryptBinaryToString", _
            "ptr", DllStructGetPtr($struct), _
            "int", DllStructGetSize($struct), _
            "int", 1, _
            "ptr", 0, _
            "ptr", DllStructGetPtr($strc))

    If @error Or Not $a_Call[0] Then
        Return SetError(1, 0, "") ; error calculating the length of the buffer needed
    EndIf

    Local $a = DllStructCreate("char[" & DllStructGetData($strc, 1) & "]")

    $a_Call = DllCall("Crypt32.dll", "int", "CryptBinaryToString", _
            "ptr", DllStructGetPtr($struct), _
            "int", DllStructGetSize($struct), _
            "int", 1, _
            "ptr", DllStructGetPtr($a), _
            "ptr", DllStructGetPtr($strc))

    If @error Or Not $a_Call[0] Then
        Return SetError(2, 0, ""); error encoding
    EndIf

    Return DllStructGetData($a, 1)

EndFunc   ;==>_Base64Encode

 

Func _Base64Encode($sData)
    Local $oXml = ObjCreate("Msxml2.DOMDocument")
    If Not IsObj($oXml) Then
        SetError(1, 1, 0)
    EndIf

    Local $oElement = $oXml.createElement("b64")
    If Not IsObj($oElement) Then
        SetError(2, 2, 0)
    EndIf

    $oElement.dataType = "bin.base64"
    $oElement.nodeTypedValue = Binary($sData)
    Local $sReturn = $oElement.Text

    If StringLen($sReturn) = 0 Then
        SetError(3, 3, 0)
    EndIf

    Return $sReturn
EndFunc   ;==>_Base64Encode

@DrAhmed look at TimerInit() and TimerDiff() in the help file. You should be able to add that in to each of your functions to get an idea of the time they take.

Could you give me an example please ?

@DrAhmed There is an awesome example...in the help file for TimerDiff:

Add a TimerInit() to the top of your function, and then a TimerDiff right before your Return statement, done.

Hello.

#include <String.au3>




Local $sString = _StringRepeat("Hello Word", 1000)
Local $hTimer = TimerInit()
For $i = 1 To 100
    _Base64Encode($sString)
Next
Local $iDiff = TimerDiff($hTimer)

ConsoleWrite("_Base64Encode time elapsed: " & $iDiff & @CRLF)


$hTimer = TimerInit()
For $i = 1 To 100
    _Base64EncodeMsxml($sString)
Next
 $iDiff = TimerDiff($hTimer)

ConsoleWrite("_Base64EncodeMsxml time elapsed: " & $iDiff & @CRLF)

Saludos

Not exactly the "teach a man to fish" method, @Danyfirex;)

      Hi, I created a gui with date field but formatted as time in HH:mm. It always shows "now-time". Even if I try to set it with GUICtrlSetData.
      #include <DateTimeConstants.au3> #include <GUIConstantsEx.au3> #include <MsgBoxConstants.au3> Example() Func Example() GUICreate("My GUI get date", 200, 200, 800, 200) Local $idDate = GUICtrlCreateDate("", 20, 20, 100, 20, $DTS_TIMEFORMAT) ; to select a specific default format Local $sStyle = "HH:mm" ; Just display hours and minutes <<<<<<<<<<<<<<<<<<<<<<<<<<<< GUICtrlSendMsg($idDate, $DTM_SETFORMATW, 0, $sStyle) ConsoleWrite(GUICtrlRead($idDate) & @CRLF) GUICtrlSetData($idDate, "00:00") ConsoleWrite(GUICtrlRead($idDate) & @CRLF) GUISetState(@SW_SHOW) ; Loop until the user exits. While GUIGetMsg() <> $GUI_EVENT_CLOSE WEnd MsgBox($MB_SYSTEMMODAL, "Time", GUICtrlRead($idDate)) EndFunc ;==>Example How can I set the time field with another time and how can this field be set blank?

      Hi
      I am trying to check a number of applications are up to date and install the update if required. This will run as a shutdown script, pushed out through Group Policy.
      I am querying various registry keys to determine if
      The software is actually installed The software is at the correct version Once the need for update is determined then it calls another function to run the update.
      If the software is up to date or not installed, it moves down to the next software section which changes the registry key variables and calls the registry query function again
      I have managed to get the function for (un)installs to work but I am having trouble with the registry query function

      Hi all,
       
      I was pondering over a question with regards to the speeds of reading something and did not see this kind of question in a forum search.
      The question: What is (technically) faster? Multiple reads from the same 3d array cell, or only once make a 'temp' variable from that cell and read the value from this? I don't know if either has any real impact at all anyway, but just wanted to ask anyway. :-)
       
      There may be a difference if the value holds an integer or a string (or something else) but in my case, is a simple integer.
      To hopefully clarify with a small bit of code:
      $process = $start - 15 If $xy[$process][3] <> "x" Then If _ArraySearch($open, $process, 1, $open[0][0], 0, 0, 1, 1) <> -1 Then UpdateOpen($xy[$process][5], $closed[0][0]) ElseIf $start > 0 And _ArraySearch($closed, $process, 1, $closed[0][0], 0, 0, 1, 0) = -1 Then Add_open($start, $closed[0][0], $counter, $process) EndIf EndIf You can read from this, that the array $closed[0][0] is being read 3 times. And this goes on further in the code I did not show.
      My question boils down to this, should I make a 'temp' variable to hold that $closed[0][0] value until the function is done?
       
      It may not have a real impact on my small script, but I really am interested in the answer at least.
       
      Regards,
      Tri.

      Hi guys
      I need to get time of different city, London, Jerusalem, Mosca and many others. My starting script:
      #include <Date.au3> Local $iUTC, $iHour, $iMinute, $iSecond $iUTC = _Date_Time_GetSystemTime() $iHour = DllStructGetData($iUTC, "Hour") $iMinute = DllStructGetData($iUTC, "Minute") $iSecond = DllStructGetData($iUTC, "Second") ConsoleWrite("+UTC: " & $iHour & ":" & $iMinute & ":" & $iSecond & @CRLF) My idea was start from UTC time and then add-remove hours. But what about the DST, Daylight Savings Time? How i can know if in a country is active or not? There is an API? Example with _Date_Time_GetTimeZoneInformation it will give the current time zone settings and not for other time zone. I don't have understand if is possible or not 
      On the help i have found SystemTimeToTzSpecificLocalTime but i don't have understand how to use for other time zone...
      Thanks

      To get the current time stamp, I got the below code.
      #include <Date.au3> #include <MsgBoxConstants.au3> #include <WindowsConstants.au3> #RequireAdmin ; Under Vista the Windows API "SetSystemTime" may be rejected due to system security $td = _Date_Time_GetSystemTime() $td = _Date_Time_SystemTimeToDateTimeStr($td) $td = StringReplace($td, " ", "_") $td = StringReplace($td, ":", "_") MsgBox(0,"",$td) But it is not giving the date or time of the timezone where the system is there.
      Please suggestt
