Associative Arrays with COM

Associative Array Functions

I've seen a couple of UDFs for this on the forum. One of them I quite like. But it's still nearly not as good as this method, IMHO.

I don't recall if I discovered the "Scripting.Dictionary" COM object myself or if I got the original base code from somewhere online. I have recently searched the web (and here) hard for any AutoIt references to this, other than my own over the years I've been using this (in ffe, etc..), and I can find nothing, so I dunno. If anyone does, I'd love to give credit where it's due; this is some cute stuff! It could actually be all my own work! lol

At any rate, it's too useful to not have posted somewhere at autoitscript.com, so I've put together a wee demo.

For those who haven't heard of the COM "Scripting.Dictionary".. 

Quote

A Dictionary object is the equivalent of a PERL associative array. Items can be any form of data, and are stored in the array. Each item is associated with a unique key. The key is used to retrieve an individual item and is usually an integer or a string, but can be anything except an array. 

https://msdn.microsoft.com/en-us/library/x4k5wbx4(v=vs.84).aspx

If you've ever coded in Perl or PHP (and many other languages), you know how useful associative arrays are. Basically, rather than having to iterate through an array to discover it's values, with an associative array you simply pluck values out by their key "names".

I've added a few functions over the years, tweaked and tuned, and this now represent pretty much everything you need to easily work with associative arrays in AutoIt. En-joy!

The main selling point of this approach is its simplicity and weight. I mean, look at how much code it takes to work with associative arrays! The demo is bigger than all the functions put together! The other selling point is that we are using Windows' built-in COM object functions which are at least theoretically, fast and robust.

I've used it many times without issues, anyhow, here goes..

; Associative arrays in AutoIt? Hells yeah!

; Initialize your array ...
global $oMyError = ObjEvent("AutoIt.Error", "AAError") ; Initialize a COM error handler


; first example, simple.

global $simple
AAInit($simple)

AAAdd($simple, "John", "Baptist")
AAAdd($simple, "Mary", "Lady Of The Night")
AAAdd($simple, "Trump", "Silly Man-Child")
AAList($simple)

debug("It is said that Trump is a " & AAGetItem($simple, "Trump") & ".", @ScriptLineNumber);debug
debug("")


; slightly more interesting..

$ini_path = "AA_Test.ini"
; Put this prefs section in your ini file..
; [test]
; foo=foo value
; foo2=foo2 value
; bar=bar value
; bar2=bar2 value


global $associative_array
AAInit($associative_array)

; We are going to convert this 2D array into a cute associative array where we
; can access the values by simply using their respective key names..
$test_array = IniReadSection($ini_path, "test")

for $z = 1 to 2 ; do it twice, to show that the items are *really* there!
    for $i = 1 to $test_array[0][0]
        $key_name = $test_array[$i][0]
        debug("Adding '" & $key_name & "'..");debug
        ; key already exists in "$associative_array", use the pre-determined value..
        if AAExists($associative_array, $key_name) then
            $this_value = AAGetItem($associative_array, $key_name)
            debug("key_name ALREADY EXISTS! : =>" & $key_name & "<=" , @ScriptLineNumber);debug
        else
            $this_value = $test_array[$i][1]
            ; store left=right value pair in AA
            if $this_value then
                AAAdd($associative_array, $key_name, $this_value)
            endif
        endif
    next
next

debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug
AAList($associative_array)

debug(@CRLF & "Removing 'foo'..");debug
AARemove($associative_array, "foo")

debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug

debug(@CRLF & "Removing 'bar'..");debug
AARemove($associative_array, "bar")

debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug

func quit()
    AAWipe($associative_array)
    AAWipe($simple)
endfunc


;; Begin AA Functions

func AAInit(ByRef $dict_obj)
    $dict_obj = ObjCreate("Scripting.Dictionary")

; Adds a key and item pair to a Dictionary object..
func AAAdd(ByRef $dict_obj, $key, $val)

      I have a table I am parsing, to find specific vehicle information. I am unable to get _ArrayFindAll to return the only valid result with my test data.

      Hello,
       
      I am currently writing a program that parses a massive table from a website, and need a way to add a progress bar while parsing.
      I am currently using the function _IETableWriteToArray($oObj, True) to parse the array. I need the progress bar to update as the table is parsed, not just at the end of the parsing.
      Any help at all would be very much appreciated!
       
      *EDIT --> The array I am left with after parsing is $array[0-50000][16]

      So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how  to write it in multiple lines
      Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work
    • Zein
      By Zein
      #include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
      The first one doesn't use the comma as a delimiter. (so I get a single column array)  I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters. 

      I looked again at the documentation:
       
      #include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
      And I with or without the flags params I should be getting a 2D array due to my file being a csv. 
      I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.
