Error: Subscript used on non-accessible variable

[darrenmoore]

Hello AutoIt Forum I'm new to autoit and I'm running into a error that I do not understand.  The Error is "Subscript used on non-accessible variable.  I have two occurrences of the same code one occurrence that doesn't throw an error and the other that does.

Throws Error Snippet:

 Local $hWnd = WinWait("Intel® CCF Manager Setup", "", 10)

 Local $aClientSize = WinGetClientSize($hWnd)

 MouseClick("primary", $aClientSize[0] - 535, 50)  <-- The error happens here

 

 

Does Not Throw Error Snippet:

Local $hWnd = WinWait("Thug Caller Dashboard", "", 10)

Local $aClientSize = WinGetClientSize($hWnd)

MouseClick("primary", $aClientSize[0] - 160, 40) <-- This line does not throw an error.  

 

It is obvious that the two lines are very similar what am I missing?  Any feedback would be greatly appreciated.

Local $hWnd = WinWait("Intel® CCF Manager Setup", "", 10)
 Local $aClientSize = WinGetClientSize($hWnd)
If @error Or Not IsArray($aClientSize) Then
    MsgBox(16 + 262144, "Error", "OoOps!")
    Exit
Else
    MouseClick("primary", Int($aClientSize[0]) - 535, 50)  <-- The error happens here
EndIf

One additional error handle:

Local $hWnd = WinWait("Intel® CCF Manager Setup", "", 10)
If Not IsHWnd($hWnd) Then
    MsgBox(16 + 262144, "Error", "Window not present within 10 seconds")
    Exit 1
EndIf
Local $aClientSize = WinGetClientSize($hWnd)
If @error Or Not IsArray($aClientSize) Then
    MsgBox(16 + 262144, "Error", "OoOps!")
    Exit
Else
    MouseClick("primary", Int($aClientSize[0]) - 535, 50)  <-- The error happens here
EndIf

Thank you for the snippets. Tried type casting approach and still getting the error.

Hopefully you removed the "<-- error" before running, but if you ran the code as is, you got the error at the array stage, you did not get the error at the mouseclick stage.  Don't really care about the type casts, it's about ensuring that the array is an array at that point.

Edit:

Unless you're trying to use a variable within a function as an array without declaring it first?  But your code doesn't suggest that, but then again, you just copied code out of the help file basically.

How did you determine "where the error happens"?  Where is that code?

Here's my entire file below.  I was able to determine the error by when I run the file I get a error message that gives the error that I stated initially(Error: subscript used on non accessible variable) .  And lets me know that yes the array is not an array.  And that is why I posted the question as I am new to AutoIt.  How do I make sure the array is actually an array?  Any input you may have would be helpful.    

#RequireAdmin

#include <MsgBoxConstants.au3>

#include <Array.au3>

 

 

;set mouse coords to be relative to client area of the active window (default is relative to entire screen).

AutoItSetOption("MouseCoordMode", 2)

 

 

StartCD()

InstallCD()

 

Func StartCD()

; Run CallerDashboard

ShellExecute(@DesktopDir & "CallerDashboard-installer")

 

 EndFunc

 

Func InstallCD()

 

 ;Sleep(1500)

 SendKeepActive("Thug Caller Dashboard")

 WinWait("Thug Caller Dashboard", "", 10)

 MouseClick("primary", 340, 250, 1) ;this starts the installer

 Sleep(5000) ;waiting for CCF Manager wizard steps

 WinWait("Thug Design - CallerDashboard Setup", "", 30)

 Send("{Enter}")

Local $hWnd = WinWait("Intel® CCF Manager Setup", "", 10)

 Local $aClientSize = WinGetClientSize($hWnd)

 ;$aClientSize = Width:600 Height:470

 MouseClick("primary", $aClientSize[0] - 535, 50)

 

EndFunc

You should check to see if the WinWait and WinGetClientSize return a valid handle and array before trying to access the array.
