Declaring and initializing multi-dimension arrays

Recommended Posts



This is my first post here. I've searched through the help and these forums and haven't found what I'm looking for.

Although I have quite a bit of experience in programming, it's all quite a long time ago (COBOL and dBase/Clipper), and this is my first attempt to write something quite complex using AutoIt.

I'm writing an app that reads a single CSV file and then splits it into a number of separate arrays based on the 
sections in the original file. I then display each of the individual arrays in a ListView control.

In order to standardize my code I would like to declare the structure that each array/listview will have, by creating a
structure array that contains the following elements: 
- section name,
- number of columns,
- an array with the column headers,
- an array with the column widths

The last two sub-arrays will have a variable number of entries, equal to the second value, the number of columns.
Unfortunately, I can't get this to work, I keep getting syntax errors.

This is my structure array at present (note that the widths are just placeholders at present) :

Global $aStructures[10][4] = [_
["params",         3, ["parameter", "value", "comments"], [110, 150, 450] ], _
["notes",          1, ["note"], [500] ], _
["sizes",          8, ["name", "width", "height", "blockwidth", "blockheight", "hgridsize", "vgridsize", "comments"], [10, 10, 10, 10, 10, 10, 10, 10] ], _
["templates",      2, ["name", "comments"], [10, 10] ], _
["elements",      10, ["template", "name", "nature", "frontback", "left", "top", "width", "height", "font", "size"], [10, 10, 10, 10, 10, 10, 10, 10 10, 10] ], _
["schemes",        4, ["name", "frontbg", "backbg", "comments"], [10, 10, 10, 10] ], _
["elementcolours", 7, ["scheme", "element", "fg", "bg", "bg2", "gradtype", "gradval"], [10, 10, 10, 10, 10, 10, 10] ], _
["colours",        7, ["name", "r", "g", "b", "rgb", "hex", "sample"], [10, 10, 10, 10, 10, 10, 10] ], _
["sheets",         2, ["name", "comments"], [10, 10] ], _
["items",         10, ["sheet", "size", "template", "scheme", "qty", "f1", "f2", "f3", "f4", "f5"], [10, 10, 10, 10, 10, 10, 10, 10, 10, 10] ] _

So, two questions.

1/ Are such arrays allowed, with a variable number of dimensions ?
2/ If so, what am I doing wrong in the above code ?

Any help would be welcome.

Variable dimensions aren't supported in AutoIt. You'll need to add dummy entries and possibly a count to hold the maximum dimension(s).

You could maybe do it like this:

Global $aStructures = [ _
[["params"],         [3],  ["parameter", "value", "comments"],                                                             [110, 150, 450]] , _
[["notes"],          [1],  ["note"],                                                                                       [500]] , _
[["sizes"],          [8],  ["name", "width", "height", "blockwidth", "blockheight", "hgridsize", "vgridsize", "comments"], [10, 10, 10, 10, 10, 10, 10, 10]] , _
[["templates"],      [2],  ["name", "comments"],                                                                           [10, 10]] , _
[["elements"],       [10], ["template", "name", "nature", "frontback", "left", "top", "width", "height", "font", "size"],  [10, 10, 10, 10, 10, 10, 10, 10, 10, 10]] , _
[["schemes"],        [4],  ["name", "frontbg", "backbg", "comments"],                                                      [10, 10, 10, 10]] , _

[["colours"],        [7],  ["name", "r", "g", "b", "rgb", "hex", "sample"],                                                [10, 10, 10, 10, 10, 10, 10]] , _
[["sheets"],         [2],  ["name", "comments"],                                                                           [10, 10]] , _

For $Row = 0 To UBound($aStructures) - 1
    ConsoleWrite($aStructures[$Row][0][0] & @CRLF)

    For $i = 0 To $aStructures[$Row][1][0] - 1
        ConsoleWrite(@TAB & $aStructures[$Row][2][$i])
        ConsoleWrite(" = " & $aStructures[$Row][3][$i] & @CRLF)

Thanks for your answers.

I'd thought of using JSON rather than CSV, and haven't yet made a definite decision on what format to use, but my existing files are CSV from Excel (I'm porting an existing Excel-VBA app to a standalone executable), so initially it just seemed easier to use _FileReadToArray and _FileWriteFromArray.

@trancexx: that seems exactly what I want, I'll use your solution for now, many thanks.

@InonuTaishou: Your reply is interesting too, my initial reply about JSON was for my data files, but I could indeed use this for my structure array. I'll go with trancess's idea for now, as it seems easier to implement.

Another newbie question.

Using trancexx's solution above, how can I retrieve one of the sub-arrays.

This works :

Local $vVar = $aStructures[0][2][0] ; => "parameter"

but this doesn't :

Local $aArray = $aStructures[0][2]  ; => ["parameter", "value", "comments"]

Instead of retrieving the subarray, I get "Array variable has incorrect number of subscripts or subscript dimension range exceeded."


How can I retrieve a sub-array in one go, to then pass it as a parameter to a function ?

Thanks for your help.

That's called slicing. Write a function for it in which you'd copy elements from the original array into new one. There's no buit-in mechanism for it.

      So this may be more of a challenge of effective programming then specific to AutoIT but I want to solve this problem with AutoIT  so i'm putting it here. (If someone has a better language to solve with I'm all ears)
      So the task I'm trying to achieve is that I have multiple .CSV files that have: year, month, day, hour, value. I need to be able to sum up all the values that have the same date/time, then find which date and time has the maximum value.
      The problem is that each file may or may not have same amount of days/hours as the rest. So I need to devise a way to handle this. 
      File A   File B   File C 2018 1 1  1:00 10   2018 1 1 2:00 10   2018 1 1  1:00 10 2018 1 1  2:00 12   2018 1 1 3:00 12   2018 1 2 1:00 12 2018 1 1  3:00 14   2018 1 1 4:00 14   2018 2 1  1:00 16 2018 2 1  1:00 16   2018 2 1  1:00 16              
       Answer I want to be spit out is Feb 1st 2018 at 2:00 with value of 48
      So far I've got code to store all .CSV files to an array, then a loop to go through each csv, but not sure how to effectively manipulate the data. Keep in mind each file has over 7000 time entry points.
      If anyone can solve this that would be pretty awesome!

      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".. 
      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($associative_array) & "<=" , @ScriptLineNumber);debug AAList($associative_array) debug(@CRLF & "Removing 'bar'..");debug AARemove($associative_array, "bar") debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug AAList($associative_array) quit() func quit() AAWipe($associative_array) AAWipe($simple) endfunc ;; Begin AA Functions func AAInit(ByRef $dict_obj) $dict_obj = ObjCreate("Scripting.Dictionary") endfunc ; Adds a key and item pair to a Dictionary object.. func AAAdd(ByRef $dict_obj, $key, $val) $dict_obj.Add($key, $val) If @error Then return SetError(1, 1, -1) endfunc ; Removes a key and item pair from a Dictionary object.. func AARemove(ByRef $dict_obj, $key) $dict_obj.Remove($key) If @error Then return SetError(1, 1, -1) endfunc ; Returns true if a specified key exists in the associative array, false if not.. func AAExists(ByRef $dict_obj, $key) return $dict_obj.Exists($key) endfunc ; Returns a value for a specified key name in the associative array.. func AAGetItem(ByRef $dict_obj, $key) return $dict_obj.Item($key) endfunc ; Returns the total number of keys in the array.. func AACount(ByRef $dict_obj) return $dict_obj.Count endfunc ; List all the "Key" > "Item" pairs in the array.. func AAList(ByRef $dict_obj) debug("AAList: =>", @ScriptLineNumber);debug local $k = $dict_obj.Keys ; Get the keys ; local $a = $dict_obj.Items ; Get the items for $i = 0 to AACount($dict_obj) -1 ; Iterate the array debug($k[$i] & " ==> " & AAGetItem($dict_obj, $k[$i])) next endfunc ; Wipe the array, obviously. func AAWipe(ByRef $dict_obj) $dict_obj.RemoveAll() endfunc ; Oh oh! func AAError() Local $err = $oMyError.number If $err = 0 Then $err = -1 SetError($err) ; to check for after this function returns endfunc ;; End AA Functions. ; debug() (trimmed-down version) ; ; provides quick debug report in your console.. func debug($d_string, $ln=false) local $pre ; For Jump-to-Line in Notepad++ if $ln then $pre = "(" & $ln & ") " & @Tab ConsoleWrite($pre & $d_string & @CRLF) endfunc

      My esteemed Autoits I need your help once again.
      I'm trying to figure out how to create a loop that gets 1 value from an array and repeats until each value from the array has been used. I have never used arrays before and I know once I learn more things should get easier for me. 
      Here is what Im trying to do:
      -Have an array of values that determine what application i log into. ex: app1, app2, app3, app4 etc.
      -Have a loop that repeats a process sequentially using each value in the array to finish the process for each app1, app2, app 3 and so forth. I have 30 apps that I need to update on a regular basis and getting this sorted out is what I perceive to be the best way to do it.
      Here is my feeble attempt that obviously fails:
      #include <msgboxconstants.au3>
      #include <Constants.au3>
      #include <array.au3>
      Func Login()
          local $array[30] = ["10", "11", "12",etc etc]
          ;;Local $site = InputBox("ERx Site","What site do you want to login as?","","")
          Local $userid = InputBox("ERx Login", "What is your username?", "", "")
          Local $Passwd = InputBox("Security Check", "Enter your UAT password.", "", "*")
      for $1 = 1 to 30(I need to do the same steps in 30 different apps)
      Send (Sequential ARRAY VALUE HERE)
      WinClose("Home Page")
      your help is greatly appreciated.

      Hi All, 
      I am fairly new to AutoIT and I am still trying to learn, I have been using _FileListToArray to list all the files with a particular extension in an array and then loop through it for operation  (   For $i = 1 To UBound($FileArray) - 1).
      So far this has been working fine. But I am not able to figure out a problem that I have; what if I have 50 files but I only want to loop through first 10 files and then next ten and so on?  Or rather I should say, how I can I only feed max 10 files to the array at a time when I do _FileListToArray regardless of the total number of files in the folder?
      Any insight/help will be much appreciated
