Array variable has incorrect number of subscripts

Recommended Posts


Hi Virtual People,

My array works perfectly fine. However, what is the best practice if the line in the array doesn't have the correct amount of columns and if I can add a placeholder?


For $count = 1 To _FileCountLines($FileRead1) Step 1
    $string = FileReadLine($FileRead1, $count)
    $input = StringSplit($string, ",", 1)
    $value1 = $input[1]
    $value2 = $input[2]
    $value3 = $input[3]

    _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "A1")
    _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "B1")
    _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1")


Kind Regards

Try that : 


Local $MyVar[3] = ["element 1", "element 2", "element 3"]

MsgBox (0, "", $MyVar)
MsgBox (0, "", $MyVar[0])
MsgBox (0, "", $MyVar[1])
MsgBox (0, "", $MyVar[2]) ;This is equal to $iRow amount (3) - 1 = 2 

$iRow = UBound ($MyVar)
MsgBox (0, "", $iRow)

If $iRow > 3 Then ; With that you dodged the fact to trying to access an non accessible $Variable. in this case it was $MyVar[3]
    MsgBox (0, "", $MyVar[$iRow-4]);$MyVar[3]
    MsgBox (0, "", $MyVar[$iRow-3]);$MyVar[2]
    MsgBox (0, "", $MyVar[$iRow-2]);$MyVar[1]
    MsgBox (0, "", $MyVar[$iRow-1]);$MyVar[0]
If $iRow > 2 Then 
    MsgBox (0, "", $MyVar[$iRow-3]);$MyVar[2]
    MsgBox (0, "", $MyVar[$iRow-2]);$MyVar[1]
    MsgBox (0, "", $MyVar[$iRow-1]);$MyVar[0]
If $iRow > 1 Then
    MsgBox (0, "", $MyVar[$iRow-2]);$MyVar[1]
    MsgBox (0, "", $MyVar[$iRow-1]);$MyVar[0]
If $iRow > 0 Then
    MsgBox (0, "", $MyVar[$iRow-1]) ;$MyVar[0]

If you allow me, IsArray() doesn't tell you if you have less elements in your array and/or you array has some blank elements.
So, if you want to see if your array has less elements than the "normal", or has some blank elements, then you should do something like this:

#include <Array.au3>

Global $strIsArray = "Element1,Element2,ElementN", _
       $strLessElements = "Element1,Element2", _
       $strBlankElement = "Element1,,ElementN", _
       $arrIsArray = StringSplit($strIsArray, ",", $STR_NOCOUNT), _
       $arrLessElements = StringSplit($strLessElements, ",", $STR_NOCOUNT), _
       $arrBlankElements = StringSplit($strBlankElement, ",", $STR_NOCOUNT), _


; To detect if the array has less elements than normal, use UBound()
If UBound($arrIsArray) < UBound($arrLessElements) Then
    ConsoleWrite("$arrLessElements has elements than $arrIsArray." & @CRLF)

; To detect if the array has a blank element
For $i = 0 To UBound($arrBlankElements) - 1 Step 1
    If $arrBlankElements[$i] = "" Then ConsoleWrite("Detected a blank element at the index '" & $i & "'." & @CRLF)

; As you can see from here, only $varNotAnArray, which is not an array, displays "False" as a result of IsArray() function
ConsoleWrite("Is $arrIsArray an array? " & (IsArray($arrIsArray) ? "True" : "False") & @CRLF & _             ; True
             "Is $arrLessElements an array? " & (IsArray($arrLessElements) ? "True" : "False") & @CRLF & _   ; True
             "Is $arrBlankElements an array? " & (IsArray($arrBlankElements) ? "True" : "False") & @CRLF & _ ; True
             "Is $varNotAnArray an array? " & (IsArray($varNotAnArray) ? "True" : "False") & @CRLF)          ; False

StringSplit always returns an array, even if you use a blank line, see example below, personally I would just use the line count like in the example below or use Ubound as FrancescoDiMuro used.

#include <Array.au3>
Local $aArray, $aString[] = ["One,Two,Three", "", "Four,Five,Six,Seven,Eight","Nine,Ten"]
For $i = 0 To UBound($aString) - 1
    $aArray = StringSplit($aString[$i], ",")
    ;~ Check string has been split into three or more items
    If $aArray[0] >= 3 Then
        MsgBox(4096, "Success", "String has successfully been split into " & $aArray[0] & " line items.")
        MsgBox(16, "Failure", "String has been split into " & $aArray[0] & " line items.")

      hi all,
      reviewing the forum, this thread is applicable: 
      I wanted to know if there is now a better way to do this?
      In essence, I load a tab delimited txt file into an array (works well). I used tab, as some fields in the original csv contains commas.
      However, I needed autoit to manipulate this array, and output it as a csv.
      IF my array contains items with a comma, without double quotes around the field, then how best do I get a csv out of this?
      My current workaround is to filewritefromarray tab delimited, then open it in excel and save as a csv. I will need to check this to see how the address fields behave that contain a comma.
      Any thoughts would be appreciated.

      Hi All,

      I would like to know how you would take a FileLineRead and insert it into an array which then inserts it into Excel?
      One thing to know is the files content is broken up, so I only use half of the content within $FileRead1.
      So its imperative that the $value1, $value2, etc variables be used. 
      Code below:
      $FileRead1 = FileReadLine("C:\temp\sample.txt",1) For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] $value4 = $input[4] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value4, "D1") Next

      I'm trying to write a script that moves copies excel cells into an array. I'll than manipulate the values and send array into another program. 
      I don't want range to be specific to a workbook, or sheet, or set of cells.
      I want user to be able to highlight desired cells and to copy either normally ("Ctrl+C") or by a hotkey ("Alt+C"). 
      Could someone help me with this?
      Thank you,
      I've tried to write the framework: (edited)
      #include <MsgBoxConstants.au3> #include <Array.au3> #include <Excel.au3> HotKeySet("!v", "Pastedata") While True Sleep(1000) WEnd func Makearray() local $bArray ;User has cells already copied ;Convert clipboard into an array ;I don;t know how excel stores data to clipboard so don;t know how to bring it into array _Arraydisplay($bArray) MsgBox(0,0,$bArray) return $bArray endfunc func Pastedata() Local $aArray MsgBox(0,0,"wait",1) ;make array based on assumption user has already copied a range to clipboard $aArray = Makearray() ;paste code ;don;t worry about this I got the rest endfunc

      I want to make a while loop, that creates variables based on a array. For thist I created the array $iDsO with the number and the name of folders in an other folder. Every folder has a different name an I want to create variables(arrays) for each folder that show me all the files in that folder. For example: I have the Folder \Folder1. In it there are the Folders \1, \2, \3. In 1, 2 and 3 there are some files(.png). The array for Folder1 is $iDsO and now I want to crate the arrays $iDsO1, $iDsO2 and $iDsO3 with the files in them can I make something like this:
      While $iDs > 0 ;$iDs is the number of files in Folder1>> $iDsO[0] $iDs#here should come the Foldername for example '1'# = _FileListtoArray(@ProgramFilesDir&"\Folder1\"&$iDsO[$iDs]) $iDs = $iDs - 1 Wend So that in the End I have three variabels ($iDs1, $iDs2 and $iDs3)
      Is this posible or if not what could I do instead ( I don´t know the number of folders in Folder1 in the begining).
