AutoIt script turns off, because of array is out of bound

1 post in this topic

Hello all!

I wrote a little script to automate some of my work (for which I'm greatfull).

I have little problem now. My script get data of currency values from specified time period. The problem, if XY day is a holiday or something, then the bank doesn't have new values for that day, thus my script can ask for "till that date" if there is only data for "till that date-1".

I should be done with this for tomorrow and I should learn for my test paper tomorrow, make a genetic algorhytm homework, and at least look at a ppt...

So here is my code, pleas ask if you need more information!

InternetRead2() ;Creating Date and Arfolyam arrays, using DateInterval read from above (_ArraysDisplayed and function is "tested")
;Calculate and write HUF*OSSZEG
    Local $SZAMLATELJOlvaso = _Excel_RangeRead($ExcelObject, Default, $SZAMLATELJoszlop & $CellaOlvasoSzamlalo)
    Local $Time = StringTrimRight($SZAMLATELJOlvaso, 6)
    $DateArrayTimeIndex = _ArraySearch($DateArray, $Time, 0, 0, 0, 0, 1)
    ;MsgBox(64, "Értesítés", $DateArrayTimeIndex)

        If @error = 6 Then
            $DateArrayTimeIndex = _ArraySearch($DateArray, $Time-1, 0, 0, 0, 0, 1)
            ;MsgBox(64, "Értesítés", $DateArrayTimeIndex)
        If @error = 6 Then
            $DateArrayTimeIndex = _ArraySearch($DateArray, $Time-2, 0, 0, 0, 0, 1)
            ;MsgBox(64, "Értesítés", $DateArrayTimeIndex)
        If @error = 6 Then
            $DateArrayTimeIndex = _ArraySearch($DateArray, $Time-3, 0, 0, 0, 0, 1)
            ;MsgBox(64, "Értesítés", $DateArrayTimeIndex)
        If @error = 6 Then
            $DateArrayTimeIndex = _ArraySearch($DateArray, $Time-4, 0, 0, 0, 0, 1)
            ;MsgBox(64, "Értesítés", $DateArrayTimeIndex)

    $DateArrayTimeIndex = $DateArrayTimeIndex+1 ;Egyébként arraysearch -1et ad vissza, 0nál. Passz

    If Not $SZAMLATELJOlvaso = "" Then
    _Excel_RangeWrite($ExcelObject, $ExcelObject.Activesheet, "=" & $OSSZEGoszlop & $CellaOlvasoSzamlalo & "*" & String($ArfolyamArray[$DateArrayTimeIndex]) & "", String($sHUFBeszurOszlop) & $CellaOlvasoSzamlalo)
        If @error Then
            _Excel_RangeWrite($ExcelObject, $ExcelObject.Activesheet, "=" & $OSSZEGoszlop & $CellaOlvasoSzamlalo & "*" & String($ArfolyamArray[$oXML_Node.Length]) & "", String($sHUFBeszurOszlop) & $CellaOlvasoSzamlalo)
            MsgBox(64, "Értesítés", "Valamilyen okból, nem találok az adott dátumhoz árfolyamot, a keresési idők közül a legutolsó árfolyammal töltöttem ki!" & @CRLF & Number($oXML_Node_Datum))

    $CellaOlvasoSzamlalo = $CellaOlvasoSzamlalo + 1

    Until $SZAMLATELJOlvaso = ""

also my internetread2 function :

Func InternetRead2() ;ezt használja az excelmove

;TO DO: Some error handling maybe: what if there is no $MinTime/$MaxTime?
;Read the returns in to array for future use --> Right now, 2 arrays one with the dates and one with the exchangerates
    ;Globals decleared to avoid warnings
    Global $MinTime ;20160601000000
    Global $MaxTime ;20160610000000
    Global $MinTimeFormated = StringTrimRight($MinTime, 6)
    Global $MaxTimeFormated = StringTrimRight($MaxTime, 6)

    $oHTTP = ObjCreate("WinHttp.WinHttpRequest.5.1")
    If $MaxTimeFormated = "" and $MinTimeFormated = "" Then
        MsgBox(64, "Értesítés", "Nincsenek beolvasott dátumok a memóriában, dummy dátumokat adok meg!" & @CRLF & "20160901, 20160910")

    $ArfolyamArray[$i] = $oXML_Node_Kozep01
    $DateArray[$i] = StringTrimRight(StringReplace($oXML_Node_Datum, "-", ""), 8)

    ConsoleWrite( "Match [" & StringFormat("%02i", $i+1) & "]:"&@CRLF& _

        @TAB&"Kozep02: "&@TAB&$oXML_Node_Kozep02&@CRLF _

My problem is that I have dates in my excel till 2016.10.30, but I only have dates till 28.

(see the api, according to aoutit console, I have the same data: )

My idea/goal (with the If @error then... after @SZAMLATELJolvaso part) is that if this happens, I want it to automaticly jump to the last date of the array (I will be able to write something more elaborate, but for now thats my goal, to save the sinking ship :D )

Thank yu for your help and insight!

      I'm trying to insert the following formula in cell A2 using my script:
      =if(A1=""; "YES"; "NO")
      To my understanding, the line of code should be similar to this:
      _Excel_RangeWrite($MasterFile, Default, "=if(A1=""; "YES"; "NO")", "A2")
      However, it does not work, probably due to the multiple quotation marks that confuse the script :C
      How do I avoid this problem?

      Hi everybody,
      i have a question about Excel, i have to create several charts one below the other dynamically.
      I have thought to use:
      $oRangeLast = .UsedRange.SpecialCells($xlCellTypeLastCell) $iRowCount = .Range(.Cells(1, 1), .Cells($oRangeLast.Row, $oRangeLast.Column)).Rows.Count  
      And then to use it in this way:
      $Graph_position = "=Test1!A"&$iRowCount+2&":K"&$iRowCount+24 But it doesn't work with charts.
      Does anyone have a suggestion?

      Hi all,
      i have an empty csv file, i have a non formatted text file.
      What do i want to do?
      I want to automate the process "get external data" in Excel, i want to import the data from the text file and basically create a csv file with a specific character encoding.
      Is it possible with AutoIT?

      Haven't had much time to code recently. However the following thread inspired me.
      The debate about linear, parallel and binary search methods was rather interesting and, in an attempt to be diplomatic, I decided to combine @jchd's suggestion with @LarsJ's binary search example. I decided that the binary search algorithm required modification to make it more linear. As usual, 'if you invent something, it probably already exists and if it already exists, it exists for a reason'. My first attempt was not all that good. The code worked but was really a mess. I blame peer pressure (to post an example of a parallel search method).  I will delete that old code in due course.
      With a little memory jogging and a glance at the help file, the solution turned out to be quite easy: I just needed a better understanding of Euler. Further modification will be needed to work with more complicated unicode strings. The output could be returned as an array or a delimitered string. I'm not so interested in those details. I'm just going to post the algorithm for now and anyone, who wants to, can modify it to suit their needs. Both arrays must contain at least 1 element.
      Local $aFoo = [0,1,2,3,4,5,6,7,9,10,11,12,13,14,15,16,19,20,23,24,26,30,35,39,40,41] Local $aBar = [0,1,5,6,7,8,9,10,11,12,13,14,17,18,19,21,24,25,26,27,34,35,38,40] ParallelExponetialSearch($aFoo, $aBar) ; Compares two lists - returning positive matches. Each input array must be unique (individually) and in alphabetical order. Func ParallelExponetialSearch($aFoo, $aBar) Local $sFind, _ $iMin_F = -1, $iMax_F = UBound($aFoo) -1, $Lo_F = $iMin_F, $Hi_F, _ $iMin_B = -1, $iMax_B = UBound($aBar) -1, $Lo_B = $iMin_B, $Hi_B While $iMin_F < $iMax_F And $iMin_B < $iMax_B ; Toggle Arrays - Which array has most untested elements? This is the one we want to search next, ; so we can bypass more comparisons because (in theory) mismatches have a greater chance of being skipped. If $iMax_F - $iMin_F >= $iMax_B - $iMin_B Then ; $aFoo has more (or an equal number of) untested elements $Hi_F = $iMax_F $iMin_B += 1 $sFind = $aBar[$iMin_B] While $Lo_F < $Hi_F ; search $aFoo For $i = 0 To Floor(Log($Hi_F - $Lo_F) / Log(2)) $Lo_F = $iMin_F + 2^$i If $aFoo[$Lo_F] = $sFind Then $iMin_F = $Lo_F ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $Lo_F & "] = $aBar[" & $iMin_B & "]" & @LF) ExitLoop 2 ElseIf $aFoo[$Lo_F] > $sFind Then $Hi_F = $Lo_F -1 $iMin_F += Floor(2^($i -1)) $Lo_F = $iMin_F ContinueLoop 2 EndIf Next $iMin_F = $Lo_F ; minimum increment is one WEnd Else ; $aBar has more untested elements $Hi_B = $iMax_B $iMin_F += 1 $sFind = $aFoo[$iMin_F] While $Lo_B < $Hi_B ; search $aBar For $i = 0 To Floor(Log($Hi_B - $Lo_B) / Log(2)) $Lo_B = $iMin_B + 2^$i If $aBar[$Lo_B] = $sFind Then $iMin_B = $Lo_B ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $iMin_F & "] = $aBar[" & $Lo_B & "]" & @LF) ExitLoop 2 ElseIf $aBar[$Lo_B] > $sFind Then $Hi_B = $Lo_B -1 $iMin_B += Floor(2^($i -1)) $Lo_B = $iMin_B ContinueLoop 2 EndIf Next $iMin_B = $Lo_B ; minimum increment is one WEnd EndIf WEnd EndFunc ;==> ParallelExponetialSearch I hope this will be useful to someone. I believe it deserved a thread of its own!

      I have a requirement to return both a string and an array from a function so as a result I put them both into an array and returned that.  I can access them in their entirety after returning them but then I can't seem to access the array elements after this.  Should I be able to or is there a prettier way?
      #include <Array.au3> ;Memory info returned as a string and an array $memoryInfo = _getMemoryInfo() msgbox(0,"Memory Info",$memoryInfo[0]) _ArrayDisplay($memoryInfo[1],"Memory as an Array") Local $newArray[7] $memoryInfo[1] = $newArray msgbox(0,"Test element",$newArray[0]) _ArrayDisplay($newArray) Func _getMemoryInfo() Local $newArray[7] Local $array = MemGetStats() $newArray[0] = $array[0] ;% of memory in use $newArray[1] = Round($array[1]/1024 * 0.001,2) ;Total physical RAM $newArray[2] = Round($array[2]/1024 * 0.001,2) ;Availaible physical RAM $newArray[3] = Round($array[3]/1024 * 0.001,2) ;Total pagefile $newArray[4] = Round($array[4]/1024 * 0.001,2) ;Available pagefile $newArray[5] = Round($array[5]/1024 * 0.001,2) ;Total virtual $newArray[6] = Round($array[6]/1024 * 0.001,2) ;Available virtual $memoryUsage = $newArray[1] - $newarray[2] $pagefileUsage = $newArray[3] - $newarray[4] ;Output/Return Local $returnArray[2] $returnArray[0] = "Memory: " & $memoryUsage & " GB/" & $newArray[1] & " GB " & @CRLF & "Pagefile: " & $pagefileUsage & " GB/" & $newArray[3] & " GB " $returnArray[1] = $newArray return $returnArray EndFunc A bit messy but hopefully it's understandable what I'm trying to achieve.
