clearing Array

6 posts in this topic

is there fast and nice way to clear array? (clear all elements and probably free some memory....)

i can loop to delete element until end but i look for more elegant way :)

maybe delete and recreate array (if possible didnt find this option)

thanks!

hezi,

Just redeclare the array and it is emptied for you: :)

#include <Array.au3>

Global $aArray[3] = [1, 2, 3]

_ArrayDisplay($aArray)

Global $aArray[3]

_ArrayDisplay($aArray)

If you want to get rid of the array completely, just declare it as a simple variable - $aArray = 0. ;)

Another approach that will pass the Au3Check with advanced parameters >>

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7
#include <Array.au3>

Global $aArray[3] = [1, 2, 3]
Global $aBackup[UBound($aArray)] ; Create a blank array.

_ArrayDisplay($aArray)

$aArray = $aBackup

_ArrayDisplay($aArray)

Or another way is this >>

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7
#include <Array.au3>

Global $a1D[5] = [1, 2, 3, 4, 5]

_ArrayDisplay($a1D)

_ArrayClear($a1D)

_ArrayDisplay($a1D)

Func _ArrayClear(ByRef $aArray)
    Local $iCols = UBound($aArray, 2)
    Local $iDim = UBound($aArray, 0)
    Local $iRows = UBound($aArray, 1)
    If $iDim = 1 Then
        Local $aArray1D[$iRows]
        $aArray = $aArray1D
    Else
        Local $aArray2D[$iRows][$iCols]
        $aArray = $aArray2D
    EndIf
EndFunc   ;==>_ArrayClear

      Old fashion way search array
      By Ahile07
      Hello guys. Again a dummy question for smart people.
      I'm wondering if any of you can help me with an issue. I've got a list of names that i would like to store into an array variable. Example $names = [name1][name2][name3]
      Then i've got an inputbox that asks for your name. I don't know how i can be able to see if the inputbox value is different then the names. I've done already separate if statements if the values are = with the names. But i want to check for error in case the value of the inputbox is different then my list of names.
      Hope it makes sense.
      Thank you

      [SOLVED] Help with Array's (creating 1 Array from 2 Arrays)
      By Dent
      I just can't get my head around what I'm trying to do.
      Ok so I read all the links in a webpage into a 1D array, I then make the array unique as there are some duplicates.
      I then find all the entries I want from the array and put the number of the row for those entries into another 1D array.
      So I now have two arrays; one has unique links, the other has the numbers of the rows for the links I actually want.
      Using the second array I would like to amend the first array, or create a third, with just the links I actually want.
      Confused? Welcome to my world.
      I'll put the relevant section of code below to show where I am up to.
      I've left the _ArrayDisplay in the above code which I am using to check the code does what I wanted. So the above code works fine, I'm just stumped on how to extract the links from $aLinks that I want.
      $oLinks = _IELinkGetCollection($oIE) Local $aLinks[1] = ["Link"] For $oLink in $oLinks _ArrayAdd($aLinks, $oLink.href) Next ;_ArrayDisplay($aLinks) $aLinks = _ArrayUnique($aLinks) ;_ArrayDisplay($aLinks) $aLinksToClick = _ArrayFindAll($aLinks, "azref", 0, 0, 0, 3) ;_ArrayDisplay($aLinksToClick) Local $aSortedLinks[1] = ["Sorted Links"] For $i = 0 To UBound($aLinksToClick) - 1 $Blah = _ArrayExtract($aLinks, $aLinksToClick[$i], $aLinksToClick[$i]) _ArrayAdd($aSortedLinks, $Blah) Next

      [solved] send multiple files by email from a file list
      By Rapidnxit
      Hi! I want to send by mail some files with a certain extension (.xml in my case). These files are located in the script folder. First, I thought to use _FileListToArrayRec function to have a list of these files. But than I don't know how to send them all at once. I know that I can attach multiple files in this way: path1;path2;path3; etc.  and so I have tried to make a string of this type with the path of the files (with a for loop) but It doesn't attach any file (only instructions.txt). How could I do? ( what I did is just an idea, if there's something better that would be great) Thanks!
      $aArrayXml = _FileListToArrayRec(@ScriptDir, "*.xml", $FLTAR_FILES) _ArrayDisplay($aArrayXml, "LIST XML") $LenghtArrayXml = UBound($aArrayXml) If ($LenghtArrayXml > 2) Then For $i = 2 To $LenghtArrayXml - 1 $temp = "&@ScriptDir&""\"&$aArrayXml[$i]&";"&"""" $XmlListFile = $XmlListFile & $temp Next EndIf $XmlListFile = StringTrimLeft($XmlListFile, 1) if($LenghtArrayXml = 2)Then $rc =_INetSmtpMailCom($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body, @ScriptDir&"\"&$aArrayXml[1]&";"&@ScriptDir&"\instructions.txt", $s_CcAddress, $s_BccAddress, $s_Username, $s_Password, $IPPort, $ssl) Else $rc = _INetSmtpMailCom($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body, @ScriptDir&"\"&$aArrayXml[1]&$XmlListFile&@ScriptDir&"\instructions.txt", $s_CcAddress, $s_BccAddress, $s_Username, $s_Password, $IPPort, $ssl) EndIf

Any ideas would be very appreciated

      Array Comparison with Logical expressions
      By jonson1986
      Hello,
      I'm having list of words and put them into an array ($WordsList) and try to compare results with logical function if in such a condition that if letter extracted through _StringBetween doesn't exist in Array ($WordsList) then it'll show message box like "Pattern Not found" and if patter found in array then it'll skip if comparison and show last message "All Done". 
      But in my condition, the if comparison is not able to process commands upto my expectations and just show last message only.
      Please help me and guide me further how can i make this possible.
      $file = fileopen(@ScriptDir & "\source.txt", 10) $IE = _IECreate( "http://example.com", 0, 0) $source = _IEDocReadHTML($IE) FileWrite($file, $source) Global $File = @scriptdir & "\source.txt" $sText = FileRead($File) $target_source = _StringBetween($sText, "Dateuploaded</strong><span>", "</span></li><li><strong>Seeders") _ArrayDisplay ($target_source) $WordsList = ("2daysago", "1dayago") If $target_source[0] <> $WordsList Then ; Here is the problem for logical comparison MsgBox ( '', '', 'Pattern Not found') EndIf MsgBox ('', '', 'All Done')
