Pass array directly to function? getData(["Child from A Item 0", "Child from A Item 1"])

[junkew]

Can I pass an array directly to a function?

local $ArrData[2]=["Child from A Item 0", "Child from A Item 1"]
getData($ArrData)
getData(["Child from A Item 0", "Child from A Item 1"])

func getData($arr)
    consolewrite($arr[0] & @CRLF)
    consolewrite($arr[1] & @CRLF)
EndFunc

gives error  ==> Error in expression.:

getData(["Child from A Item 0", "Child from A Item 1"])
getData(^ ERROR

Hi @junkew.

No i don't think you can.

If you want to use an array directly, something like this maybe:

getData(StringSplit("Child from A Item 0,Child from A Item 1",",",2))

You can use the first form of your call to the function, the second one won't work.

This will work fine to pass an array to the function.

getData($ArrData)

Ok then I will change it to something like this (any coding advice on this? my arguments are fixed to 4)

Below I feel is cleaner then a stringsplit but any other way of coding is welcome

Set $NetCollection=ObjCreate("System.Collections.Sortedlist")

$NetCollection.Add("one", getDataArray("Child A from one", "Child B from one", "Child C from one", "Child D from one"))
$NetCollection.Add("two", getDataArray("Child A from two", "Child B from two", "Child C from two", "Child D from two"))

...

func getDataArray($v1, $v2, $v3, $v4, ..., $v255) 
    $arr[4]
    
    $arr[0]=$v1
    $arr[1]=$v2
    $arr[2]=$v3
    $arr[3]=$v4
    
    return $arr
endfunc

Why don't you just create the array, then pass it to the function? Isn't that what you asked about?

[junkew]

local $ArrData[2]

$ArrData[0]="Child A from one", "Child B from one", "Child C from one", "Child D from one"
$ArrData[1]="Child A from two", "Child B from two", "Child C from two", "Child D from two"

Set $NetCollection=ObjCreate("System.Collections.Sortedlist")

$NetCollection.Add("one", $arrData[0])
$NetCollection.Add("two", $arrData[1])

Background

I am playing a little around with treeview, listview and .NET collections (to enhance simplespy of Examples IUIAutomation thread) and as an end result where you see "one", "two" i should have the handle of the treeviewitem so easy and quick to lookup data in a limited set of rows in a collection/array (I assume below 1000 items in the treeview).

So the array is not static upfront (will contain the UIA property information which either is collected on the fly or coming from an XML or INI file)
