_Array1DTo2D

Recommended Posts

We often have to get a 2D from a 1D array. A good example is with StringRegExp : it can only return a 1D array. But it can be interesting to transform the result to a 2D array.

Of course, it's easy to make it, but I think this function could help someone.

First, an example :

; #EXAMPLE# =====================================================================================================================
#Include <Array.au3>

Local $sString =  "<select>" & @CRLF & _
                  "  <option value='volvo'>Volvo</option>" & @CRLF & _
                  "  <option value='saab'>Saab</option>" & @CRLF & _
                  "  <option value='mercedes'>Mercedes</option>" & @CRLF & _
                  "  <option value='audi'>Audi</option>" & @CRLF & _
                  "  <option value='porsche'>Porsche</option>" & @CRLF & _
                  "</select>"
Local $aValues = StringRegExp($sString, "value='([^']+)'>([^<]+)", 3)
_ArrayDisplay($aValues, "1D Array")

Local $aValues2D = _Array1DTo2D($aValues, 2, 0, 0, 0)
_ArrayDisplay($aValues2D, "2D Array")
; ===============================================================================================================================

Now, the function :

; #FUNCTION# ====================================================================================================================
; Name ..........: _Array1DTo2D
; Description ...: Transforms a 1D to a 2D array.
; Syntax ........: _Array1DTo2D($avArray, $iCols[, $iStart = 0[, $iEnd = 0[, $iFlag = 0]]])
; Parameters ....: $avArray             - Array to modify.
;                  $iCols               - Number of columns to transform the array to.
;                  $iStart              - [optional] Index of array to start the transformation. Default is the first element.
;                  $iEnd                - [optional] Index of array to stop the transformation. Default is the last element.
;                  $iFlag               - [optional] If set to 1, the array size must to a multiple of $iCols. Default is 0.
; Return values .: Success : Returns a 2D array
;                  Failure : Returns 0 and sets @error to :
;                    1 - $aArray is not an array
;                    2 - $iStart is greater than $iEnd
;                    3 - $aArray is not a 1D array
;                    4 - $aArray size is not a multiple of $iCols
; Author ........: jguinch
; ===============================================================================================================================
Func _Array1DTo2D($avArray, $iCols, $iStart = 0, $iEnd = 0, $iFlag = 0)

    If $iStart = Default OR $iStart < 0 Then $iStart = 0
    If $iEnd = Default Then $iEnd = 0

    If NOT IsArray($avArray) Then Return SetError(1, 0, 0)
    If UBound($avArray, 0) <> 1 Then Return SetError(3, 0, 0)

    Local $iUBound = UBound($avArray) - 1

    If $iEnd < 1 Then $iEnd = $iUBound
    If $iEnd > $iUBound Then $iEnd = $iUBound
    If $iStart > $iEnd Then Return SetError(2, 0, 0)

    Local $iNbRows = ($iEnd - $iStart + 1) / $iCols
    If $iFlag AND IsFloat($iNbRows) Then Return SetError(2, 0, 0)

    Local $aRet[ Ceiling($iNbRows) ][$iCols]
    Local $iCol = 0, $iRow = 0
    For $i = $iStart To $iEnd
        If $iCol = $iCols Then
            $iCol = 0
            $iRow += 1
        EndIf
        $aRet[$iRow][$iCol] = $avArray[$i]
        $iCol += 1
    Next

    Return $aRet
EndFunc

I hope it is clear enough

      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") Next

      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

      Hello,
      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).
