Array Comparison

[torels]

Hi there

Is there a way to compare 2 arrays (Possibly using a different way than _ArraySearch)

I thought of sorting them and then compare every single index but as soon as you get a mismatch, the whole thing stops working

tanks in advance

What is your script so far? please post it, then I'll be able to help you further.

I havn't got a script.

I was just trying to see if there are better ways of comparing a script than using _arraysearch

my idea was to use the biggest array of the 2 (one array always has all the other array's values in it) and do an _arraysearch...

in case of error then add that value to the list of missing ones in the other array

Try writing something first, then post what you have and what you're stuck on.

Func _Compare($aArray1, $aArray2)
    Dim $Result[1]
    $aMaxArray = _MaxArray($aArray1, $aArray2)
    $aMinArray = _MinArray($aArray1, $aArray2)
    For $i = 0 To UBound($aMaxArray)-1
        _ArraySearch($aMinArray, $aMaxArray[$i])
        If @error Then _ArrayAdd($Result, $aMaxArray[$i])
    Next
    
    Return $Result
EndFunc
    
Func _MaxArray($aArray1, $aArray2)
    If UBound($aArray1) > UBound($aArray2) Then
        Return $aArray1
    Else
        Return $aArray2
    EndIf
EndFunc

Func _MinArray($aArray1, $aArray2)
    If UBound($aArray1) < UBound($aArray2) Then
        Return $aArray1
    Else
        Return $aArray2
    EndIf
EndFunc

here is what I have

Is there a better way of doing it ?

I think that's quite a good way, I even think it's the best.
