Size of 2 dimensional array.

Does anyone know how to determine the size of 2 dimensional array?

the following script works, until $x becomes larger than the size of the array.  Then it errors out.  I would prefer a more graceful exit.

$aPrinterList = _EnumPrinterProperties("*")
$x=-1
While 1
      $x=$x+1
      $queue=$aPrinterList[$x][6]
      If @error<>0 then ExitLoop                               ;<---------------------------------------------------------
      If $queue=$oldPrinter then
            _RemovePrinter($oldPrinter)
            _AddWindowsPrinterConnection($newPrinter)
            If $aPrinterList[$x][18]="True" Then _SetDefaultPrinter($newPrinter)
      EndIf
WEnd

Your logic is off on your condition statements too.

Does $aPrinterList[$x][18] return a string?  That's what you're comparing it too, more likely it returns a boolean.

You're checking @error on something that cannot return an "@error".

Global $aPrinterList = _EnumPrinterProperties("\\*")
If Not IsArray($aPrinterList) Then
    Exit 2
EndIf

; validate ubound 2nd dim
If (UBound($aPrinterList, 2) - 1) < 18 Then
    Exit 3
EndIf

Global $queue, $oldPrinter, $newPrinter

For $x = 0 To UBound($aPrinterList, 1) - 1
    $queue = $aPrinterList[$x][6]
    If $queue = $oldPrinter Then
        _RemovePrinter($oldPrinter)
        _AddWindowsPrinterConnection($newPrinter)
        If $aPrinterList[$x][18] Then
            _SetDefaultPrinter($newPrinter)
        EndIf
    EndIf
Next

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Thank you both.  Ubound() is exactly "what the doctor ordered."
SmOke_N, I tried both boolean and string.  both work, yet both return an error.  After some additional testing, i found i don't need it at all.  If the default printer is removed, the next printer installed becomes default by default (no pun intended)
