How can one loop through a multi-dimentional associative array?

[LWC]

For...In...Next:

If the expression is a multi-dimensional array, the loop will be skipped and the Variable will contain an empty string.

So how is one supposed to loop through a multi-dimentional associative array ($array["foo"]["bar"])?

Thanks!

For $row=0 To UBound($array,1)-1
    For $column=0 to UBound($array,2)-1
        ;some code
    Next

;some code

But that's exactly the missing part. How can I display or edit what's inside $array[$row][$column], which won't work because they're numbers.

For $r=0 To UBound($array,1)-1
    For $c=0 to UBound($array,2)-1
        MsgBox(0,"",$array[$row][$column]) ;Will display a Message Box with that Array's Cell content
    Next
Next

It would be alot easier to help with your problem if you post some code, and tell us what your trying to achieve, at this point, trying to guess what you need is as easy as picking the correct number out of 10 billion

to edit a given cell try

$array[$row][$column] +=1

or

$text="New Name"
$array[$row][$column] =$text

Again, I'm talking about associative arrays. For example:

$array["foo"]["bar"]="bla"
$array["foo"]["test"]="something"

Your loop code won't work with associative arrays. How can I iterate through multi-dimentional associative arrays?

How are you creating the array? It's not build-in, or even a standard UDF.

The best way to figure you how to get data from a source is finding out how it was put in there in the first place.

As @Tvern said, AutoIt does not natively support the types of arrays you are referencing.

[LWC]

I'm creating it manually:

dim $array[1][2]
$array["foo"]["bar"]="bla"
$array["foo"]["test"]="something"

Now I just to loop through it. AutoIt supports such arrays. For example, I can do:

msgbox(0, "", $array["foo"]["bar"])

I just need to know how to loop through it.

Hmm, it seems "test" overwrites "bar".

I am sorry, I overlooked the word associative, which is a bit over my head, but I did find a couple items of interest in the forums, there is a UDF that deals with multidimensional associative arrays here http://www.autoitscript.com/forum/index.php?showtopic=113182&st=0

Also another that has a function,_Key_GetKeys(ByRef $kArray) , to get an array of keys, which might help in looping and is found here http://www.autoitscript.com/forum/index.php?showtopic=93489&st=0&p=671577&hl=associative%20array&fromsearch=1&#entry671577

That's not an associative array. Autoit doesn't have them natively.

Instead all strings (in this case) are evaluated as "0", so you're just writing values to $array[0][0] all the time.

If you want to use associative arrays you'll have to search for a UDF that you like, or write one yourself.

As Tvern said, you are faking yourself out. AutoIt does not support associative arrays natively. AutoIt variables are also not strictly typed, so when you pass a string where an integer is required for the index, there is an attempt to convert it silently as if by $array[int("foo")][int("bar")], which evaluates to $array[0][0]. This shows the actual results of your code:

#include <Array.au3> ; only for _ArrayDisplay()

dim $array[1][2]

$array["foo"]["bar"]="bla"
_ArrayDisplay($array, "$array")

$array["foo"]["test"]="something"
_ArrayDisplay($array, "$array")
