Get array's number of slots in use?

Recommended Posts

So I was looking everywhere about getting an array's number of slots in use... and found nothing.

Is this even possible? for example

Global $array[5]

$array[1] = "1 slot in use"

$arrayslotsinuse = ArrayGetSlotsInUse($array)

Thanks in advance :)

...I tried making a counter but didn't work so well.. (it crashed app)

TheNewHunter,

UBound will tell you how many elements are in the array, but not how many are "in use" - often the coder uses the [0] element to keep a count as the array fills.

If you're looking to include a counter, I would suggest creating a function for adding data to your array.

ReDim is your friend here! 

Example;

#Include<Array.au3> ;Used to display results (_ArrayDisplay)
local $array[1] ; Initialise the array

;Now lets add something to it
AddValueToArray($array,"Dave")
AddValueToArray($array,"Phil")
AddValueToArray($array,"Jake")
_ArrayDisplay($Array) ;Show Results
;Now lets remove Phil, But we want our counter and array to remain neat
RemValueFromArray($array,"Phil")
_ArrayDisplay($Array) ;Show Results



func AddValueToArray( byRef $iArray,$iValue)
    local $uBound = uBound($iArray,1) ;Get max element number of array
    reDim $iArray[$uBound + 1] ;Re Dimension the array, Without removing information
    $Array[$uBound] = $iValue ; Add the new value
    $Array[0] += 1 ; Increment the counter by 1
EndFunc

Func RemValueFromArray( byRef $iArray,$iValue)
    local $tArray = $iArray ;Store data in a temporary array
    Dim $iArray[1] ;Reset the array to empty (so we can rebuild it)
    for $i = 1 to $tArray[0] ;Loop through temporary array
        if $tArray[$i] = $iValue then ContinueLoop ;We've found the remove value! Lets continue the loop and ignore it.
        AddValueToArray($iArray,$tArray[$i]) ;The above line was false, So we can run the AddValueToArray Command to add the data
    Next ;Continue the for loop
EndFunc

Cheers

      to smth. like
       
      Here is my Code
      #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <array.au3> #include <File.au3> $filedir = @ScriptDir & "\" _checkfile() Func _checkfile() ConsoleWrite("______________________" & @CRLF) Local $arr[3] = ["music", "picture", "video"] For $i = 0 To UBound($arr) - 1 Local $arrayfiles = _FileListToArray($filedir & $arr[$i], $arr[$i] & "*", 1) If @error = 1 Then ConsoleWrite($arr[$i] & "Error 1") EndIf If @error = 4 Then ConsoleWrite($arr[$i] & "Error 2") ;Exit EndIf $arrayfilter = _ArrayMax($arrayfiles, 0, 1) Global $stringfiles = StringReplace($arrayfilter, $arr[$i], "") ConsoleWrite($arrayfilter & @CRLF) Next EndFunc ;==>_checkfile
