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)

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.


Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind._______My UDFs:


ArrayMultiColSort ---- Sort arrays on multiple columns
ChooseFileFolder ---- Single and multiple selections from specified path treeview listing
Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
Toast -------------- Small GUIs which pop out of the notification area

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! 


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

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

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



give a man an application, and he'll be frustrated for the day, Teach him how to program applications and he'll be frustrated for a lifetime.

      To save myself a "search" nightmare, I'm trying to wrap my head around 3D arrays.
      Example: In "No Limit Hold'em", if I only play kings "KK" and queens "QQ"
      and I only play them from the positions of the "Button" or "Blinds"
      and do one thing if it's raised ahead or another if not raised.
      I know that this example would be simple as a 2D array but if I'm dealing with 77 possible hands in 9 possible positions and 6 possible conditions then I'm dealing with almost 700 data lines.
      Lastly, if I have a variables to represent the hand like $hand = "QQ"
      and $position = "Button" and $ahead = "Raised", could the 3D array simplify my search, or should I just stick to the 2D array ??
      Thank you in advance for any thoughts...

      So I have a loop that keeps reading data from an array and searching it for the same value. If the value is no there it does work then adds the value to the array to prevent it from doing the same work.
      If _ArraySearch($ID,$filearray[$i]) = -1 Then Work.... _ArrayAdd($ID,$filearray[$i]) EndIf This is in a for loop hence $i
      So what is happening is the code works great for several hours. After a period of time _ArraySearch($ID,$filearray[$i]) will result in -1 even if $ID = $filearray. So it ready as if there is no data in the array. Anyone have this problem? 
      Also I am just running in using F5 not compiling it and running it if that makes a difference.

      I am reading a CSV file which is tab seperated as below.
      Local $aArray = FileReadToArray($file) And now, I am splitting this main array record wise so that Array contains internally another arrow to represent each row.
      For $i = 0 to (UBound($aArray) - 1) ;MsgBox(0,"",$aArray[$i]) $aArray[$i] = StringSplit(StringStripCR($aArray[$i]), Chr(9),2);Chr(9) for tab ;_ArrayDisplay($aArray[$i]) Next Afther that, _ArrayDIsplay is able to see the individual internal arrays.
      _ArrayDisplay($aArray[1]) But If I try to access the individual element of it as below.It is not showing any result.
      MsgBox(0,"",$aArray[1][1]) Any suggestion, below is the sample csv file.
      New Text Document.csv
