Multi-Dimentional Array Question

[SpookMeister]

Is there a way to compare multi-dimentional arrays as a whole, without itterating through the array?

Something like this: (which doesnt work BTW)

expandcollapse popup

HotKeySet("{ESC}", "Terminate")
HotKeySet("{F5}", "compare")
HotKeySet("{F6}", "changeA")
HotKeySet("{F7}", "changeB")

Global $testA[3][3]
Global $testB[3][3]

For $x = 0 to 2
    for $y = 0 to 2
        $testA[$x][$y]=111
        $testB[$x][$y]=111
    Next
Next

while 1
    Sleep(1000)
WEnd

Func compare()
    If $testA = $testB Then
        MsgBox(0,"Compare","They are the same")
    Else
        MsgBox(0,"Compare","They do not match")
    EndIf
EndFunc

Func changeA()
    $testA[1][1]=121
EndFunc

Func changeB()
    $testA[1][1]=111
EndFunc

Func Terminate()
    Exit
EndFunc

Sorry, no way, other than to loop through the array and compare values.

Currently, there is no built-in feature for comparing arrays, other than looping through and comparing element by element.

What would the requirements for equality be?

• Same number of dimensions
• Each dimension is the same size
• Same contents for corresponding elements

At different times, it is important to know which of these conditions failed. Just asking $a = $b doesn't let you know why it failed. You can check that when you are doing the looping to compare.

Well, I guess I could write something like, but it is not my highest priority right now. Work, bug fixes, Work AutoIt debugger, etc. Hmm I do have Variant rewrite on my to-do list. Maybe I can sneak it in there. This may show up in the beta, but do not expect it for a while.

if you're comparing to see if the arrays are exactly the same, i remember a while back someone made a UDF that works like _ArrayToString() to convert a multidimensional array to a string... you could find that UDF (i know i saw it in this forum, but they may have posted a finished product in scripts and scraps also) and convert both arrays to strings then compare the strings.
