So I have been in and out of AutoIt for a few years now and I've never come across a situration where I'd need to verify if an a variable is an array or not.

So here's the deal - I have a database that contains 1 table with a few different columns. When a user initially opens the script, it will see if their "username" pulled from @UserName is stored in the database (which is always unique).

If their username is not in the database, it inserts a record (using EzMySql) including their username, full name (pulled from ->

_AD_Open()

Global $adFullName = _AD_GetObjectAttribute(@UserName, "DisplayName")

Global $uSName = @UserName

_AD_Close()

<-), Time Stamp, Accept Flag (0/1) and Deny Flag (0/1).

This is all irrelevant at this point but I just wanted you to understand what I am doing here.

Anyways, I am getting to the point to where I am storing specific values from the table into variables. EzMySql will store the data in an array (IF the query finds results) however if it does not, then the variable will not be an array.

The problem is, when I run my "If statements" - if I check the variable, there is no way for me to know if the results are stored in array format or not.

Here's an example, read the comment above $LookupUser.

Func _CheckDatabase()
; Obtain user's Full Name and store as variable.

If Not _EzMySql_Startup() Then
    MsgBox(0, "Error Starting MySql", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

$Pass = "D@#!$dD(#d0939kd(#Dk3093d)(#D039039ddk39dkd"

If Not _EzMySql_Open("10.3.3.11", "rug_user", $Pass, "rug", "3306") Then
    MsgBox(0, "Error opening Database", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMYSql_Query("SELECT * FROM accept_list WHERE Username = '" & @UserName & "';") Then
MsgBox(0, "Query Error", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMySql_SelectDB("rug") Then
    MsgBox(0, "Error setting Database to use", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

$LookupUser = _EzMySql_FetchData()


;This is the problem - if there is no data found, $LookupUser[1] for example will not work returning an error. This function currently works but I need more functionality.

If $LookupUser == 0 Then
$sMySqlStatement = "INSERT INTO accept_list (Username,FullName) VALUES (" & "'" & $uSName & "'," & "'" & $adFullName & "');"
    If Not _EzMySql_Exec($sMySqlStatement) Then
        MsgBox(0, "Error inserting data to Table", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf
ElseIf $LookupUser <> 0 Then
    _CheckFlags()
    ;Call function to verify if user has accepted or not.
EndIf
_EzMySql_Close()
_EzMySql_ShutDown()
Return
EndFunc

Did you check the IsArray() function?

And also UBound() will help verifying arrays size.

Thank you both - this solved my issue entirely! I tested it using the following and ensured that I had "
#include <Array.au3>
" included.:

If IsArray($LookupUser) Then
MsgBox(0, "Variable Array Check", "Your variable is an array - hurray!")
Else
MsgBox(0, "Variable Array Check", "Your variable is not an array - awww.")
EndIf

Thanks again guys!

#include <Array.au3>
is not needed to use function "IsArray". IsArray is part of AutoIt itself.

      I have a string containing the full path of an executable and an array of executables without their paths. I am trying to compare the string to the list in the array and if a match is found, remove it from the array. The entry get removed from the array successfully, and after checking its return result, uses it to update the ubound if it succeeded, but it doesn't want to update to the new value. Any ideas what I am doing wrong? It acts like it is read-only.
      #include <Array.au3> #include <File.au3> Local $sApp_Exe = "F:\App\Nextcloud\nextcloud.exe" Local $aWaitForEXEX = [3, "Nextcloud.exe", "nextcloudcmd.exe", "QtWebEngineProcess.exe"] For $h = 1 To $aWaitForEXEX[0] If StringInStr($sApp_Exe, $aWaitForEXEX[$h]) <> 0 Then $iRet = _ArrayDelete($aWaitForEXEX, $h) If $iRet <> -1 Then $aWaitForEXEX[0] = $iRet ;this line doesn't work. $aWaitForEXEX[0] doesn't update and shortly gives Error: Array variable has incorrect number of subscripts or subscript dimension range exceeded.: _ArrayDisplay($aWaitForEXEX) EndIf Next

      #Include <Array.au3> #include <Constants.au3> $s = FileRead("2.txt") Local $w = StringRegExp($s, '(?is)(\b\w+\b)(?!.*\b\1\b)', 3) _ArrayColInsert($w, 1) For $i = 0 to UBound($w)-1 StringRegExpReplace($s, '(?i)\b' & $w[$i][0] & '\b', $w[$i][0]) $w[$i][1] = @extended Next _ArraySort($w, 1, 0, 0, 1) _ArrayDisplay($w) i have this script that returns 3 columns  
       
      i need to copy the  Col 0 and Col 1 as text to paste on notepad or excel
      you will have to create a "copy" button if possible

      I have a dataset like this, (a strubg)
      Username: User1 Type: Admin RegDate: 1999 Username: User2 Type: User RegDate: 2000 How to make a 2 dimensional array that I can display with _ArrayDisplay?
      This would be a perfect 2D array to represent my data:
      Username           Tpye RegDate User1              Admin 1999 User2              User 2000   If you run this Powershell this powershell command, you can get this dataset that I am talking about:
      Get-LocalUser | Select * With this code you can try it to read into a string:
      #include <GuiConstantsEx.au3> #include <WindowsConstants.au3> #include "GUIListViewEx.au3" #include <Array.au3> ; Just for display in example #RequireAdmin #Region ;**** Directives created by AutoIt3Wrapper_GUI **** #AutoIt3Wrapper_UseX64=y #EndRegion $sCommand = "powershell.exe Get-LocalUser | Select *" Local $iPid = Run($sCommand, @WorkingDir , @SW_SHOW , $STDOUT_CHILD) ProcessWaitClose($iPid) Local $sOutput = StdoutRead($iPID) ConsoleWrite($sOutput) How can I correctly split $sOutput into a 2D array (with the above mentioned layout) that I can display and I work with?

      My solution is to write nested arrays without copying.
      The problem was described hier.

      I have already read some forum answers here, and I have already tried these commands:
       
      Are there any way to use the $aOutput variable like in PowerShell:
      PowerShell:
      $a = Get-ChildItem $a.Mode I imagine this in AutoIt  $aOutput
      ConsoleWrite($aOutput[i].Mode) Or if I split this command into 2 dimension like:
      For $i To UBound($aOutput)-1 Step 1 ConsoleWrite($aOutput[$i][1]) ConsoleWrite($aOutput[$i][2]) Next
