[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

      Hello, i'm making a little script that lets users enter a question and if the script can't answer to, it ask what would be the answer (a bit like siri on IPhones). And I try to display the "supposed array" I still have an error.. I searched on Google and got nothing looked in the help file too.. I'm here to know if someone have a solution to my error please.
      Here is where $a and $b should become arrays :
      Dim $dossier = @AppDataDir & "\Siri2" Dim $chemin = $dossier & "\data.ini" Global $a = _InfoRead($chemin, 0) Global $b = _InfoRead($chemin, 1) with this function :
      Func _InfoRead($path, $mode = 0) If DirGetSize($dossier) = -1 Then Return SetError(-4) If Not FileExists($chemin) Then Return SetError(-5) Local $readed = IniReadSection($path, "data") If @error Then Return SetError(-3) $size = $readed[0][0] Local $return[$size] For $i = 1 To $size Step 1 $return[$i - 1] = $readed[$i][$mode] Next Return $return EndFunc and the thing that i don't understand is that, after _InfoRead return affected to $a, I can't use _ArrayDisplay because of  error 1 "$aArray is not an array" (and same fpr the variable $b)..
      Can please someone help me to understand why is it doing this ?

      I'm new to Auotit but I have built a simple script that "runs" a different "batch" file based on certain days of the workweek. The script works now, but I was wanting to eliminate the need for a manual date entry. For example "First Batch' needs to run every Tuesday thru Thursday however "Second Batch" needs to run only on Friday and "Third Batch" needs to run only on Monday. In addition the 1st batch file runs on Tuesday, say 06/06 (the "FW" section) but then needs to actually report (the F4 date) the next weekday so this Batch actually needs 2 dates verified. 
      What I'm trying to do is when the script is initiated it gets the date, verifies if and which weekday it is and in turn goes to and runs the appropriate "Batch' file.  
      I've found ways to verify weekdays but can't find anything to do all of the above.
      Any help is MUCH appreciated.

      Hi, can anybody explain "pure virtual function" and how to make use of them?

      After Several Minutes searching the forums for a simple solution to calculating for the Unix Time, as required for another project I am working on, I was astonished to not find one clean and universal solution. After looking over the helpfile, I noticed one simple solution given in the example with _DateDiff(). However it did not account for my current timezone or daylight savings time.
      Without further ado... This is my example of Calculating for a current Unix Time stamp or  seconds since Jan, 1st, 1970 00:00:00 GMT.
      This function will account for your timezone as well as for daylight savings time.
      Update: v0.3
      -Added Function to revert a Unix Time stamp into Date form.
      -Added parameter to original _GetUnixTime() allowing for a custom date since Jan 1st 1970 to be passed and converted to Unix Time.
      #include <Date.au3> #include <Array.au3> #include <Constants.au3> Local $iUnixTime1 = _GetUnixTime() MsgBox($MB_SYSTEMMODAL, "Unix Timestamp", "Seconds Since Jan, 1st, 1970 00:00:00 GMT" & @CRLF & $iUnixTime1) Local $sUnixDate1 = _GetDate_fromUnixTime($iUnixTime1) MsgBox($MB_SYSTEMMODAL, "Unix Timestamp", "Get Date from Unix Timestamp in Local Time" & @CRLF & $sUnixDate1) $sUnixDate1 = _GetDate_fromUnixTime($iUnixTime1, False) MsgBox($MB_SYSTEMMODAL, "Unix Timestamp", "Get Date from Unix Timestamp with $iReturnLocal = False which returns UTC Time" & @CRLF & $sUnixDate1) Local $iUnixTime2 = _GetUnixTime('2013/01/01 00:00:00') MsgBox($MB_SYSTEMMODAL, "Unix Timestamp", "Seconds since 2013/01/01 00:00:00" & @CRLF & $iUnixTime2) ; Get timestamp for input datetime (or current datetime).

Func _GetDate_fromUnixTime($iUnixTime, $iReturnLocal = True) Local $aRet = 0, $aDate = 0 Local $aMonthNumberAbbrev[13] = ["", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"] Local $timeAdj = 0 If Not $iReturnLocal Then Local $aSysTimeInfo = _Date_Time_GetTimeZoneInformation() Local $timeAdj = $aSysTimeInfo[1] * 60 If $aSysTimeInfo[0] = 2 Then $timeAdj += $aSysTimeInfo[7] * 60 EndIf $aRet = DllCall("msvcrt.dll", "str:cdecl", "ctime", "int*", $iUnixTime + $timeAdj ) If @error Or Not $aRet[0] Then Return "" $aDate = StringSplit(StringTrimRight($aRet[0], 1), " ", 2) Return $aDate[4] & "/" & StringFormat("%.2d", _ArraySearch($aMonthNumberAbbrev, $aDate[1])) & "/" & $aDate[2] & " " & $aDate[3] EndFunc ;==>_GetUnixDate Enjoy!

      Hello, I am new to both Programming and this forum. I have done a few tiny projects that were successful and fell in love with Autoit. So now I am trying to learn new things as I go. I have read the Help docs on my following question, I have gone thru all of that. and I am sure as soon as you see my code you will be saying OMG why did he do that, or OMG how can you forget to add this.. But when your new you take the path of least resistance to get the outcome you want.

      SETUP:
      I am trying to make a code that will open a piece of software, then open a browser (which has a handful of tabs already open) go to a web page (one of the tabs) and search an area of the web page for a specific color, if that color is found I want it to close the browser and go back and start again. If that color is not found on that page I want it to switch tabs and search that page for the color. If the color is found on that page I want it to close the browser and start again. If the color is not found on either page, I want it to open another browser and go to website and do some things I will add once i get past this obstacle.

      I already have it almost there my code will open my software, open the browser, do the searches, find or not find the color, the part I am having trouble with is the if and else and what happens if and what it does if it does not. So the first code I have does everything I want except if it finds the color on the first run it closes the browser, but then when it starts the process again it doesnt check for the color. its like it skips the scanning part and goes straight to the opening of the second browser and finishes the code.
      Run( "C:\Programs\myprogram.exe", "", @SW_SHOWDEFAULT ) Sleep(4000) MouseClick("left", 613,272) ;click in program Sleep(500) Example() Func Example() MouseClick("left", 632,456) ;click in program Sleep(500) MouseClick("left", 527,456) ;click in program Sleep(15000) Run( "C:\Programs\browser1.exe", "", @SW_SHOWMAXIMIZED ) Sleep(Random(4000,6000)) EndFunc ;==>Example MouseClick("left", 162,14) ;switch tab Sleep(Random(5000,8000)) MouseClick("left", 354,14) ;switch tab Sleep(Random(5000,8000)) $aCoord = PixelSearch(873, 485, 900, 600, 0xDD0000, 10) ;search for color If Not @error Then MouseClick("left", 1338,6) ;close browser1 Sleep(1000) Call("Example") Else MouseClick("left", 162,14) ;switch tab Sleep(1000) EndIf MouseClick("left", 162,14) ;click tab again just to be sure its loaded Sleep(4000) $aCoord = PixelSearch(1052, 308, 1120, 431, 0xFF0000, 10) ;search for this color If Not @error Then MouseClick("left", 1338,6) ;close browser1 Sleep(1000) Call("Example") Else Run( "C:\Programs\browser2.exe", "", @SW_SHOWMAXIMIZED ) Sleep(2000) EndIf MouseClick("left", 134,45) ;click on address bar Sleep(1000) Send("aspecificwebpage.com") ;input website Send("{enter}") ;hit enter Sleep(15000) MouseClick("left", 1338,6) ;close browser2 Sleep(500) MouseClick("left", 1338,6) ;close browser1 Sleep(500) MouseClick("left", 625,454) ;click in program Sleep(500) MouseClick("left", 634,271) ;click in program Sleep(500) MouseClick("left", 917,245) ;close program Sleep(500) SO it makes the first scan and is successful, if the color is found it closes as I want, but then when nit starts the code again it does not scan anything the second time.

      and on the other side, if the color is not found naturally everything works as it is written.
      I want to guess by all the weird colors in the code sniplet I have a massive amount of errors. It is like a rainbow of text up there. different from what i see in AutoIT

      Any help would be appreciated.
