Hello,

I need to assign data to array:

Global $Test[3][4]
$Array = "Test"
SetArrayData($Array,"Hello world!",1,3)
ConsoleWrite($Array[1][3]&@CRLF)
Exit
Func SetArrayData($Array,$Data,$1,$2)
    $Array[$1][$2] = $Data; <-- ???
EndFunc

I need that somebody would help me with that function :)

You're trying to assign a value to an array that is not actually an array?

You'll need to test if the variable being passed is an array or not. If it's not then create a temporary array and assign it ByRef.

#include <Array.au3>

Global $aTest1[3][4]
Global $sTest2 = "Test"
Global $aTest3[1]

SetArrayData($aTest1, "This is Row 2, Column 3", 2, 3)
If (@Error) Then SetArrayError(@Error, "$aTest1")
SetArrayData($sTest2, "This is Row 9, Column 3", 9, 3)
If (@Error) Then SetArrayError(@Error, "$sTest2")
SetArrayData($aTest3, "This is Row 2, Column 2", 2, 2, False)
If (@Error) Then SetArrayError(@Error, "$aTest3")

_ArrayDisplay($aTest1)
_ArrayDisplay($sTest2)
_ArrayDisplay($aTest3)


Func SetArrayData(ByRef $aArray, Const ByRef $sData, Const ByRef $iRow, Const ByRef $iColumn, Const $ReDim = True)
    If (Not IsArray($aArray)) Then
        ConsoleWrite("$aArray is not an array" & @LF)
        If (Not $ReDim) Then Return SetError(-1, 0, False)
        Local $aTemp[$iRow + 1][$iColumn + 1]
        $aArray = $aTemp
        ConsoleWrite("Converted $aArray to proper array" & @LF)
    EndIf

    If ($iRow >= UBound($aArray, $UBOUND_ROWS)) Then
        ConsoleWrite("Assigning to row " & $iRow & " when rows in $aArray are " & UBound($aArray, $UBOUND_ROWS) & " | Index out of range" & @LF)
        If (Not $ReDim) Then Return SetError(1, 0, False)
        ReDim $aArray[$iRow + 2][$iColumn + 1]
        ConsoleWrite("Increased $aArray row count to " & UBound($aArray, $UBOUND_ROWS) & @LF)
    EndIf

    If ($iColumn >= UBound($aArray, $UBOUND_COLUMNS)) Then
        ConsoleWrite("Assigning to column " & $iColumn & " when columns in $aArray are " & UBound($aArray, $UBOUND_COLUMNS) & " | Index out of range" & @LF)
        If (Not $ReDim) Then Return SetError(2, 0, False)
        ReDim $aArray[$iRow + 1][$iColumn + 2]
        ConsoleWrite("Increased $aArray column count to " & UBound($aArray, $UBOUND_COLUMNS) & @LF)
    EndIf

    $aArray[$iRow][$iColumn] = $sData
    Return True
EndFunc

Func SetArrayError($iError, $sVar)
    Switch ($iError)
        Case -1
            MsgBox("", "SetArrayData Error", $sVar & " passed to SetArrayData was not an actual Array and $ReDim was set to false")
        Case 1
            MsgBox("", "SetArrayData Error", "Row passed to SetArrayData was out of range for the variable " & $sVar & " and $ReDim was set to false")
        Case 1
            MsgBox("", "SetArrayData Error", "Column passed to SetArrayData was out of range for the  " & $sVar & " and $ReDim was set to false")
    EndSwitch
EndFunc

    EndSwitch
EndFunc

 

Thank You, but what I need to do if it's just array name? Example:

;...
Global $Array1[3][4]
Global $Array2[3][4]
Global $Array3[3][4]
;...
For $i = 1 to 3
    SetArrayData("Array"&$i,$i,1,1)
Next
;Random...
For $i = 1 to 3
    SetArrayData("Array"&Random(1,3,1),"Hello world!",Random(0,2,1),Random(0,3,1))
Next
;...

No, I'm not trying to assign a value to an array that is not actually an array.

This works:

Global $Test[3][4]
$Array = $Test
SetArrayData($Array,"Hello world!",1,3)
ConsoleWrite($Array[1][3]&@CRLF)
Exit
Func SetArrayData(ByRef $Array,$Data,$1,$2)
    $Array[$1][$2] = $Data; <-- ???
EndFunc

I think this is kind of what you're trying to accomplish then? Using Assign and Eval. You can't assign it in the actual function itself because you're trying to use the variables as strings. Eval and Assign don't actually assign/eval values in arrays, they just work on the variable itself. If you use Eval you can get the whole array, but you can't use ByRef in the SetArrayData function. Instead, return an array and use Assign to do what you want.

#include <Array.au3>

Global $aTest1
Global $aTest2
Global $aTest3
Global $ReDimArray[] = [False, True, True, False]

For $i = 1 to 3
    Local $iRow = Random(0, 4, 1)
    Local $iColumn = Random(0, 4, 1)
    Assign("aTest" & $i, SetArrayData(Eval("aTest" & $i), "This is Row " & $iRow & ", Column " & $iColumn & " for array $aTest" & $i, $iRow, $iColumn))
Next

_ArrayDisplay($aTest1, "$aTest1")
_ArrayDisplay($aTest2, "$aTest2")
_ArrayDisplay($aTest3, "$aTest3")

Func SetArrayData($aArray, Const ByRef $sData, Const ByRef $iRow, Const ByRef $iColumn, Const $ReDim = True)
    If (Not IsArray($aArray)) Then
        ConsoleWrite("$aArray is not an array" & @LF)
        If (Not $ReDim) Then Return SetError(-1, 0, False)
        Local $aTemp[$iRow + 1][$iColumn + 1]
        $aArray = $aTemp
        ConsoleWrite("Converted $aArray to proper array" & @LF)
    EndIf

    If ($iRow >= UBound($aArray, $UBOUND_ROWS)) Then
        ConsoleWrite("Assigning to row " & $iRow & " when rows in $aArray are " & UBound($aArray, $UBOUND_ROWS) & " | Index out of range" & @LF)
        If (Not $ReDim) Then Return SetError(1, 0, False)
        ReDim $aArray[$iRow + 2][$iColumn + 1]
        ConsoleWrite("Increased $aArray row count to " & UBound($aArray, $UBOUND_ROWS) & @LF)
    EndIf

    If ($iColumn >= UBound($aArray, $UBOUND_COLUMNS)) Then
        ConsoleWrite("Assigning to column " & $iColumn & " when columns in $aArray are " & UBound($aArray, $UBOUND_COLUMNS) & " | Index out of range" & @LF)
        If (Not $ReDim) Then Return SetError(2, 0, False)
        ReDim $aArray[$iRow + 1][$iColumn + 2]
        ConsoleWrite("Increased $aArray column count to " & UBound($aArray, $UBOUND_COLUMNS) & @LF)
    EndIf

    $aArray[$iRow][$iColumn] = $sData
    Return $aArray
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>
      Login()
      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 $1 = 1 to 30(I need to do the same steps in 30 different apps)
      run("Z:launch.exe")
      WinWaitActive("Input")
      Send (Sequential ARRAY VALUE HERE)
      Send("{ENTER}")
      WinWaitActive("window")
      Send($userid)
      Send("{TAB}")
      send($Passwd)
      Send("{ENTER}")
      WinWaitActive("[CLASS:SunAwtDialog]")
      Sleep(500)
      WinClose("Home Page")
      Next
      EndFunc
       
      your help is greatly appreciated.
      Thanks for your time

      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

      I'm trying to get an array from a website so that I can just get the url, but I am not sure how. I read a bit of arrays but I have a feeling I'd have to be writing a lot more than what I should be. I will include the script I have so far and the API url for what I want.
       
      API: https://api.fast.com/netflix/speedtest?https=true&token=YXNkZmFzZGxmbnNkYWZoYXNkZmhrYWxm&urlCount=1 (I want the 'url' array that contains the url)
       
      Code:
      #include <MsgBoxConstants.au3> #include <Inet.au3> #include <Array.au3> $site = _INetGetSource('http://api.fast.com/netflix/speedtest?https=true&token=YXNkZmFzZGxmbnNkYWZoYXNkZmhrYWxm&urlCount=1') MsgBox($MB_SYSTEMMODAL, "Title", $site[1])

      Alright, currently I'm trying to merge two loops:
       
      Local $aArray[99][13] For $iLoop = 1 to 100 $aArray[$iLoop - 1][0] = RegEnumKey("HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration", $iLoop) If @error <> 0 Then ReDim $aArray[$iLoop - 1][13] ExitLoop EndIf Next For $iLoop1 = 0 to UBound($aArray, 1) - 1 For $iLoop2 = 1 to 12 $aArray[$iLoop1][$iLoop2] = RegEnumKey("HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\" & $aArray[$iLoop1][0], $iLoop2) If @error <> 0 Then ExitLoop Next Next  
      into one. Here's what I have so far:
       
      Local $aArray[99][13] For $iLoop1 = 0 to UBound($aArray, 1) - 1 For $iLoop2 = 0 to 12 ConsoleWrite("Loop1 = " & $iLoop1 & ", Loop2 = " & $iLoop2 & @CRLF) If $iLoop2 = 0 Then $aArray[$iLoop1][0] = RegEnumKey("HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration", $iLoop1 + 1) If @error <> 0 Then ReDim $aArray[$iLoop1 + 1][13] ExitLoop EndIf Else $aArray[$iLoop1][$iLoop2] = RegEnumKey("HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\" & $aArray[$iLoop1][0], $iLoop2) If @error <> 0 Then ExitLoop EndIf Next Next And it keeps error-ing out trying to exceed the dimension range of the array. Does the Loop not recheck the size of the array after the original check or am I doing something else wrong.
       
      Thanks.

      Hi guys! How are you? Hope you're fine
      I'm trying to use SQLite for managing some data, and, I would like to display my "retrieved" data, but I'm trying to do a select from 2 table, and seems to not work properly...
      What I'd like to do is retrieve data from 2 tables and display in a listview...
      I tried with:
      Local $aRisultato, $iRighe, $iColonne, $iRVal $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Rockwell, Magazzino_Siemens;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then ;_SQLite_Display2DResult($aRisultato) _ArrayDisplay($aRisultato) EndIf ... but it displays a single record 41 times, and it does this thing for every record in the database...
      What do you need to help me?
      Thanks  

      EDIT:
      Managed with a double If and double query like this:
       
      $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Rockwell;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then Local $aRisultatoRockwell = $aRisultato $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Siemens;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then _ArrayConcatenate($aRisultato, $aRisultatoRockwell) Local $i, $sRiga, $s_LV_Item For $i = 1 To Ubound($aRisultato) - 1 $sRiga = $aRisultato[$i][0] & "|" & _ $aRisultato[$i][1] & "|" & _ $aRisultato[$i][2] & "|" & _ $aRisultato[$i][3] & "|" & _ $aRisultato[$i][4] & "|" & _ $aRisultato[$i][5] & "|" & _ $aRisultato[$i][6] & "|" & _ $aRisultato[$i][7] & "|" & _ $aRisultato[$i][8] & "|" & _ $aRisultato[$i][9] & "|" & _ $aRisultato[$i][10] & "|" & _ $aRisultato[$i][11] $s_LV_Item = GUICtrlCreateListViewItem($sRiga, $lv_Lista) Next And so, the listview is created
      If anyone has another more efficient way, I'm here Thanks guys
