Subscript Used on Non-Accessible Variable WinGetPos error

Recommended Posts

Func workSpaceSetup ()
   ConsoleWrite ("workSpaceSetup" &@CRLF)
   $workSpace = WinGetHandle ("some site - Google Chrome")
   ConsoleWrite ($workSpace&@CRLF)
   $pos1 = WinGetPos ($workSpace)
   WinMove ($workSpace , "", $pos1[0] , $pos1[1] , 1366, 768, 0)
EndFunc

(26) : ==> Subscript used on non-accessible variable.:
WinMove ($workSpace , "", $pos1[0] , $pos1[1] , 1366, 768, 0)
WinMove ($workSpace , "", $pos1^ ERROR
>Exit code: 1    Time: 0.1179

So the script is first, the error I get is second in the quote.

This is one function of many for an app I am building but it is the first one that runs so I know there aren't other things at play here.

The idea is to keep the window in the same space it is when the script runs but just resize it as this app is used across multiple computers with different screen resolutions.

Could someone please elaborate upon what "Subscript used on non-accessible variable" means? 

Oh and the variable is declared as "Global $pos1 = 0" at the top outside of any functions with the other global variables.

Any advice would be greatly appreciated!

If a function can set the @error flag, you should always check it before using a return value - if @error indicates an error then the function return value is generally undefined...

@error is always set to 0 when entering in a function.

Example:

Func workSpaceSetup ()
   ConsoleWrite ("workSpaceSetup" &@CRLF)
   $workSpace = WinGetHandle ("some site - Google Chrome")
   If @error then Return SetError(1,0,0)
   
   ConsoleWrite ($workSpace&@CRLF)
   $pos1 = WinGetPos ($workSpace)
   If @error then Return SetError(2,0,0)
   
   WinMove ($workSpace , "", $pos1[0] , $pos1[1] , 1366, 768, 0)
EndFunc

 

EDIT: Your problem was that you not check if this window title exist, and in next step if WinGetPos returns array

I also get this error regularly with the code (and I am checking for existence):

Func cancelGillickQuestionWindow()

;logMSG("cancelQuestionWindow")
    ; Close the do you want to switch to open (viewing documents) window
    $win1Title = "[TITLE:Question]"
    If  WinExists($win1Title) Then
        $winPos = WinGetPos($win1Title)
        If $winPos[0] = 106 And _
           $winPos[1] = 327 And _
           $winPos[2] = 737 And _
           $winPos[3] = 369 Then
            WinActivate($win1Title)
            Send ( "{ALTDOWN}d{ALTUP}")     ; Defer decision
        EndIf
    EndIf
EndFunc

I do apologise after "fixing" the code posting as per mLipok I pasted my current func which included a return which bypassed it completely (I've now removed the immediate return call)

I've added the edits and integrated your suggestion into my logging system (which will save it to text file), but if I don't get the error in the next hour before I leave work (it's caused by a particular automatic popup window which I can't manually trigger), so I'll post the results here next week.

Thanks for the super-prompt suggestions.

      I am going through the AutoIt Wiki and soaking up a lot of great information.  On the “Best Coding Practices” page at https://www.autoitscript.com/wiki/Best_coding_practices#Scopes_of_Variables there seems to be a minor detail missing.  In the “Variable Initialization” section at https://www.autoitscript.com/wiki/Best_coding_practices#Variable_Initialization , there are references to a data type $o, but in the table listing prefixes and their data types, there does not appear to be a prefix “o”.  I assume that this is for Object?

      Hi Folks
      Can not get my head around this one.
      This function gets the DNS object s
      If you have two DNS entries fine. but if you have only one! Trouble
      $objItem.DNSServerSearchOrder[0] = Primary DNS
      $objItem.DNSServerSearchOrder[1] = Secondry DNS not always there. I need a way to return 0 if not there or the IP if its there.
      Or is there a way to tell how many objects there are in the "[?]"
      I'm terrible at WMI errors, thanks for help in advance.
      Func _GETcurrentNICinfo2() $oErrors = ObjEvent("AutoIt.Error", "Error_Handle") Local $DnsSecondry Local $objWMIService = ObjGet( "winmgmts:\\" & @ComputerName & "\root\CIMV2" ) Local $query = $objWMIService.ExecQuery("SELECT DNSServerSearchOrder FROM Win32_NetworkAdapterConfiguration WHERE Index = " & _GetSelectedNIC(), "WQL", 0x30 ) If @error Then Return 0 If NOT IsObj($query) Then Return 0 Else For $objItem In $query Return $objItem.DNSServerSearchOrder[1] next Endif EndFunc
