Possible Maps Bug (Beta)

Recommended Posts

Can somebody try to reproduce this bug?

It would be helpful to know if this issue appeares on other environments too.


Sometimes values of certain keys will return empty even if expicitly assigned a value before.


  • Map is bigger than ~50 key/values pairs
  • value is being worked with in a Function where a loop is iterating through the Map
  • before retrieving the value there is a isMap/MapKeys/MapAppend/MapRemove check on the Map value.
Dim $mMap[]

; Generate random key strings
For $i = 0 To 100
    $RndKey = ""
    For $i2 = 0 To 4
        $RndKey &= Chr(Random(65,90,1))
    $mMap[$RndKey] = 999

ConsoleWrite("-----------1-------------" & @CRLF); Unpredictable blank values


ConsoleWrite("-----------2-------------" & @CRLF); ByRef always works


ConsoleWrite("-----------3-------------" & @CRLF); not in a function always works

For $i In MapKeys($mMap)
    ConsoleWrite($i&": "&$mMap[$i]&@CRLF)

Func MapDisplay1( $m_Map )
    For $i In MapKeys($m_Map)
        isMap($m_Map[$i]) ;same problem with isMap($m_Map[$i]), MapKeys($m_Map[$i]), MapAppend/MapRemove but NOT with MapExists($m_Map,$i)
        ConsoleWrite($i&": "&$m_Map[$i]&@CRLF)

Func MapDisplay2( ByRef $m_Map ) 
    For $i In MapKeys($m_Map)
        ConsoleWrite($i&": "&$m_Map[$i]&@CRLF)


The value is not lost or overwritten on the global map, only on the local map inside the function.

      I was searching for a way to highlight zones (regions, provinces, counties, etc) on a map, and I don't need  super precise maps so I wrote this script, based on picking up black and white maps (2 colors BW .png or .gif tested) and filling them with colors, writing down a sqlite database to associate zones with names (and other data as well), and reuse the map and the DB to display data, in my example reading a simple .txt file.
      It's all based on this thread  and this other thread.

      So I have two modes:
      The Map "creation mode" : you provide a map image and you start to pick up colors, set "upper level" region/state, and by clicking on a region you fill it and you name it, and all the data are saved on a sqlite DB (auto-created) when you have the map image and a DB with the correct associations, you can switch the "mode" to "show" (as by .ini file) and the script tries to read a "datafile" showing the zone names listed in datafile. The code:

      To test, copy all in a single folder and adjust the mapflooder.ini, also you can add to you includes the _gollog.au3 (used for log, you can avoid it deleting all Gollog() lines)

      I'm using Maps (and I love 'em!), so I have to use the latest AutoIt Beta. I've switched to Beta mode, and the graphical debugger doesn't even show up in the Explorer context menu (not surprising). So I'd like to use _Dbug (rather than a large number of MsgBox statements), but it fails when it encounters a Map function (such as MapExists). I've made a request for a version that will work with the Beta, but going on past history, I don't expect an answer anytime soon.
      I'm not necessarily asking for someone else to modify _Dbug, because I can probably do it myself, as long as I know how to adapt it to use the Beta. Can someone please enlighten me as to how to adapt a UDF or other function to use AutoIt Beta?

      Hello Everyone,
      Hoping someone can help me,
      I am totally stuck on this problem,

      I cannot reach the textarea and the button in a maps page that I get by clicking on a button in a previus page, the only way I can interact with this is using tab and mouseclick but this is a danger method as  you know.

      I get the handle by using: $Posizione = _IEAttach("Ricerca Indirizzo su mappa")

      then I tried a lot of things but nothing works, can someone give me a hint?
      WinWait("Ricerca Indirizzo su mappa")
      $Posizione = _IEAttach("Ricerca Indirizzo su mappa")
      WinSetState ("Ricerca Indirizzo su mappa", "", @SW_MAXIMIZE  )
      WinActivate("Ricerca Indirizzo su mappa")
      ;~ $oForm = _IEFormGetObjByName($Posizione, "form1");Punta il Form
      $oText = _IEFormElementGetObjByName($Posizione,"indirizzo")
      $oText = _IEFormElementGetObjByName($Posizione,"writeAddress")

      ;~ $LenteTestoMess = _IEFormElementGetValue($oText);Inserisce il PrimoRepertorio nella variabile
      ;~ _IELinkClickByText($Posizione, $oForm);Clicca su Aggiorna ed invia il form
      _IEFormElementSetValue ($oText,"via Ravenna 12" );Completamento campo testo

      Im not sure if this is intended but normally Autoit variables are always passed as copies (except objects i think).
      But below i observed an unconsistency when copying maps with nested maps inside.
      If you create a nested map1 and copy it to a new map2, changing a nested value in map2 will also change the nested value in map1
      Dim $player[] Dim $sub[] $player.test1 = 1 $player.test2 = $sub $player.test2.child1 = "org" $player.test2.childext = $sub $player.test2.childext.child1 = "org2" $playerold = $player ; make a copy of the whole map ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original nested value in $player $playerold.test2.child1 = "changed" ; edit a nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF) ; original nested value in $player changed ConsoleWrite("---------------------" & @CRLF) ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player $playerold.test2.childext.child1 = "changed2" ; edit a level2 nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original level1 nested value in $player stayed the same ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player changed

      Hi there,
      I have a problem using the latest two betas of au3stripper.exe.
      Compiling my script using V17.224.935.6 works fine, the next two releases (18.624.1847.0 and 18.624.1847.1) show an error:
