Wow this looks cool, I am sure it will come in handy.  I just sort of got comfortable with Arrays not too long ago, I assume that Maps are going to be sort of like RegEx.

"The best practice is to not use them unless you need them" and still stick to Arrays for most tasks.

I would love to see some real life examples however of where a map can more easily do what an array could not so that I can sort of wrap my head around when this would be best used or make a task easier.

I can't think use of maps too :P, But I guess I will eventually discover its use :)

use a For..In Loop, instead of a For...To Loop.     Unless thats bad form, imho it looks cleaner.

$mParkMap["Map Item 1"] = "Cottan Candy Stand"
$mParkMap["Map Item 2"] = "Public Toilet"
$mMapOfMapsvilla["Map Item 3"] = "Woods"

I don't get that bit.

Are you deliberately moving the woods in the park to the shopping mall in mapsvilla?

You can also keep your Funcs in your map with your data

; Lets create our map first
Local $mMap[]

; Lets add some information to the map, feel free to modify & add new elements
$mMap["Name"] = "Damon Harris"
$mMap["Alias"] = "TheDcoder"
$mMap["Gender"] = "Male"
$mMap["Age"] = 14
$mMap["Location"] = "India"
$mMap["Keys"] = MapKeys($mMap)


For $Key In $mMap["Keys"]
    If $Key <> "Keys" Then msgbox(0, '' , $Key & " = " & $mMap[$Key])
next

I really don't like documenting alpha (not beta) functionality in the open Forum, because it's suggesting that this will at some point be included in a future release of AutoIt, unless @TheDcoder has been told something I don't know about?!

@guinness I think I will update the introduction to be more specific on the current stage of development of maps :)

@TheDcoder has been told something I don't know about?!

Ummm... Maybe.... Maybe Not :P

i would want to explore maps in maps to achieve the OP.  start at the smallest unit throwing them into larger and larger containers..

Local $mMapGlo[]
Local $mMapLocAus[]
Local $mMapLocDal[]
Local $mMapPersonNorth[]
Local $mMapPersonSouth[]
Local $mMapPersonDallas[]


$mMapPersonNorth["Jeff"] = "Jeff in N. Austin"
$mMapPersonSouth["Jack"] = "Jack in S. Austin"
$mMapPersonDallas["John"] = "John in Dallas"

$mMapLocAus["NorthAus"] = $mMapPersonNorth
$mMapLocAus["SouthAus"] = $mMapPersonSouth
$mMapLocDal["Dallas"] = $mMapPersonDallas

$mMapGlo["CentralTx"] = $mMapLocAus
$mMapGlo["NorthTx"] = $mMapLocDal


For $loc in $mMapGlo
    For $key in mapkeys($loc)
        For $item in $loc[$key]
            msgbox(0, '' , $key & @LF & $item)
        Next
    Next
next

Are Maps similar to dynamic arrays? If you are inserting or deleting from a Map, does it work faster than an array?

maps are similar to scripting.dictionary which is similar to an ini which i guess is similar to a 2D array with equal signs?

@MartinMarris  I thinks its a yes... I am not familiar with the concept of dynamic arrays but a quick google search explained me about them, though I didn't use them, I can say that a Map is similar (not same) to dynamic arrays, Resizing a map (i.e adding or removing elements from it) is faster compared to arrays.

 

Sorry for late reply, I was busy, TD :)

      I have a program that is read data from the .txt file, since the .txt file is only readable, viewable and editable for the admin user.
      But how could I lock it with password, or some other technique that can helps to achieve this?

      Hi all,
      I need to use ControlMove() on some controls of a hidden GUI window.
      This works properly on a GUI window created with default style, but does not work on a GUI window created with style $WS_OVERLAPPEDWINDOW
      func GUItest($bOverlapped) $m = GUICreate("test", 200, 100, -1, -1, $bOverlapped ? $WS_OVERLAPPEDWINDOW : -1) $g = GUICtrlCreateButton("test", 0, 0) ControlMove($m, "", $g, 30, 30) GUISetState() endfunc GuiTest(false) ; button 'test' properly moved to (30,30) GuiTest(true) ; button 'test' not moved and still sitting at (0,0) Any reason for this unexpected behavior ?
      Any workaround to fix this ?
      Thanks for any help

      Hi all..
      I'm having slight issue that has be a bit puzzled.
      I have an Input control.. After a certain function runs, it Disables that Input control, and sets it to ReadOnly.
      When running another certain function, it re-Enables that Input control, and sets the style back to Default.
      Which does work, however, when typing into the Input control after re-Enabling it, the text appears as a light gray color, rather than its original black color.
      I'm sure there's a simple solution here.. But what that is, appears to be beyond me.
      Here is a simplified example code:
      #include <ButtonConstants.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #Region ### START Koda GUI section ### Form= Global $Form1 = GUICreate("Form1", 245, 215, 192, 124) Global $disableBTN = GUICtrlCreateButton("Disable", 32, 64, 75, 25) Global $enableBTN = GUICtrlCreateButton("Enable", 128, 64, 75, 25) Global $Input1 = GUICtrlCreateInput("", 32, 120, 169, 21) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $disableBTN disable() Case $enableBTN enable() EndSwitch WEnd Func disable() GUICtrlSetState($Input1, $GUI_DISABLE) GUICtrlSetStyle($Input1, $ES_READONLY) EndFunc Func enable() GUICtrlSetState($Input1, $GUI_ENABLE) GUICtrlSetStyle($Input1, $GUI_SS_DEFAULT_INPUT) EndFunc  
      Any help would be greatly appreciated
      Thank you in advance!

      Hi all,
      I'm trying to create a script that runs a JSON-query and then can retrieve some variables out of the returned, decoded object using JSON.au3. I have tried some other examples on this forum, but I'm stuck at one point. My query works perfectly and gets loaded into the variable $data. Then, decoding $data to $object seems to work as well. But then I can't get the date-field out of this JSON-structure with my script.
      The JSON-structure returned looks like this:
      { "content": [ { "id": "451ec583-8f27-4926-82a3-a2d85e57a110", "createdDate": "2018-08-08T08:40:57.449004Z", "updatedDate": "2018-08-08T08:40:57.449004Z", "lastOpenedDate": "2018-08-08T08:40:57.449004Z", "date": "2018-04-26T00:00:00", "description": "X-Ray Exam", "patient": { "id": "f857238a-c75d-4760-b8d1-8f50f8f9bbfa", "createdDate": "2018-08-08T08:40:37.623976Z", "updatedDate": "2018-08-08T08:40:37.623976Z", "lastOpenedDate": "2018-08-08T08:40:37.623976Z", "name": "Fuerstonia", "birthDate": "2014-06-08", "breed": "", "chip": "", "color": "", "damsire": "", "sire": "", "neutered": false, "orthancUuid": "", "sex": "U", "species": "Paard", "ueln": "De 431310762114", "pmsReference": "", "origin": "" }, "type": "study", "accessionNumber": "KME201806960467", "instanceUid": null, "orthancUuid": "", "sent": false, "seriesCount": 0, "modalityType": "RX", "typeAndModality": "study RX", "client": { "id": "be627195-8458-4927-8446-f1ef37b917a4", "createdDate": "2018-08-08T08:40:31.433968Z", "updatedDate": "2018-08-08T08:40:31.433968Z", "lastOpenedDate": "2018-08-08T09:26:49.512298Z", "via": "", "extraInfo": "", "pmsReference": "", "contact": { "id": "406cc555-c491-4c29-b6bb-8d903f0e35a9", "createdDate": "2018-08-08T08:40:31.428968Z", "updatedDate": "2018-08-08T08:40:31.428968Z", "lastName": "Client 1", "firstName": "", "company": "", "email": "", "language": "nl", "phone": "", "address": { "id": "6fc7703c-137a-4e0a-ba96-8c7f38f2044b", "city": "", "country": "", "line": "", "postalCode": "" } } } }, My script looks like this:
      #RequireAdmin #include <json.au3> #include <inet.au3> #include <File.au3> ;Create a handle to a logfile (will be created if it doesnt exist) Global $logfile = FileOpen("C:\VSOL\VSTK\Logs\MigrationFix\MigrationFix.log",9) FileWriteLine($logfile,"Start script") ;Create the URL with the JSON-query $URL = "http://localhost:8080/v0/studies/?seriesCount=1" ;Catch the query output into a variable $data = _INetGetSource($URL) ;Check if there is any data at all in this variable, if not, exit If Not $data Then MsgBox(1,"Error","No answer.

Anyone who can point me in the right direction?
