IE page refresh kills script

[chachew]

My script is monitoring a page and changing some text on screen, script works fine until the page is refreshed...then it kills the script with error:

C:\Program Files (x86)\AutoIt3\Include\IE.au3 (3013) : ==> The requested action with this object has failed.:

$oTemp.innerText = $newvalue

$oTemp.innerText = $newvalue^ ERROR

Is there a way to keep the script running regardless of if there is a momentary lapse in form read?

#include <IE.au3>
 
$oIE=_IECreate("...\Test.html")
$varForm=_IEFormGetObjByName($oIE,"form1")
 
While 1
$varText=_IEGetObjById($oIE,"line1")
$varTextGet=_IEPropertyGet($varText, "innertext")
Sleep(1000)
_IEPropertySet($varText,"innertext","This is the result of the script changing the text")
WEnd

Attached is the test.html file i am trying this on.

Of course. You need to add, what's known as COM error handler. The key function is ObjEvent(). Read about it in help file.

If you would have problems then, ask again.

After reading about the COM error handling, not sure where to begin..Im guessing if an error occurs to tell the function to restart?

Global $oErrorHandler = ObjEvent("AutoIt.Error", "ObjErrorHandler")
;your code

Func ObjErrorHandler()
    ConsoleWrite("A COM Error has occured!" & @CRLF & @CRLF & _
            "err.description is: " & @TAB & $oErrorHandler.description & @CRLF & _
            "err.windescription:" & @TAB & $oErrorHandler & @CRLF & _
            "err.number is: " & @TAB & Hex($oErrorHandler.number, 8) & @CRLF & _
            "err.lastdllerror is: " & @TAB & $oErrorHandler.lastdllerror & @CRLF & _
            "err.scriptline is: " & @TAB & $oErrorHandler.scriptline & @CRLF & _
            "err.source is: " & @TAB & $oErrorHandler.source & @CRLF & _
            "err.helpfile is: " & @TAB & $oErrorHandler.helpfile & @CRLF & _
            "err.helpcontext is: " & @TAB & $oErrorHandler.helpcontext & @CRLF _
            )
EndFunc   ;==>ObjErrorHandler

That works UEZ, thanks.

Question is why does this work, this is new to me...sorry for a n00b question. I guess the original way that i had it written, when the error occurred, autoit didnt know how to handle the error so it fails. The ObjEvent() captures those events and does what ever the function specifies based on the error type? Am i understanding this correctly?

Thanks for your help
