IE.au3 Help needed

[Teldin]

C:\PROGRA~1\AutoIt3\Include\IE.au3 (2659) : ==> The requested action with this object has failed.:

$o_object.document.execCommand ("Refresh")

$o_object.document^ ERROR

Basically I have a timed script that opens a web page (after I log in) and ever 10 mins or so checks the site for changes. I get an error If I get logged out because while the object is still valid, the Refresh command fails as the specified page cannot be accessed. I dont mind any of this but my script crashes. I need to gracefully error and continue with my script. How can I do that?

Here is some code:

expandcollapse popup

$Timer10 = TimerInit()

;portion of my main loop
While 1
    Sleep(50)
    If TimerDiff($Timer10) >= 600000  Then
        _Data1()
    Else
    EndIf
Wend

;func I'm having problems with
Func _Data1()
    GUICtrlSetData($status, "Checking news...")
    If IsObj($oIE2) Then
        _IEAction($oIE2, "refresh")
        If @error <> 0 Then              ;I recently added this IF to try and error gracefully but it didn't work
            MsgBox(0, "ERROR", "You have been logged out")
            GUICtrlSetData($status, "ERROR: Not checking news")
            $stopie = 1
        Else
            _IELoadWait($oIE2, 1000)
            $sText = _IEBodyReadText($oIE2)
            $ltrim = StringTrimLeft($sText, 115)
            $rtrim = StringTrimRight($ltrim, 301)
            If StringInStr($rtrim, "New") Or StringInStr($rtrimID, "New") Then
                GUICtrlSetData($status, "ERROR: News window lost")
                KillIE()
            Else
            EndIf
        Endif   
    Else
        GUICtrlSetData($status, "ERROR: News window lost")
        $stopie = 1
    EndIf
    GUICtrlSetData($status, "Ready...")
EndFunc

Any ideas?

I dont have your _IEErrorHandler installed. Would that help at all?

That is what it was made for.

Just add this toward the top of your script.

_IEErrorHandlerRegister()

Ok let me try that. I was thinking it only helps finding problems and I alread know what the problem is.

[Teldin]

Ok that seemed to work. It's not crashing now. Also returning the error as expected:

--> IE.au3 Error from function _IELoadWait, $_IEStatus_InvalidObjectType

--> IE.au3 Error from function _IEBodyReadText, $_IEStatus_InvalidObjectType (Expected document element)

--> COM Error Encountered in test.au3

----> $IEComErrorScriptline = 437

----> $IEComErrorNumberHex = 80010108

----> $IEComErrorNumber = -2147417848

----> $IEComErrorWinDescription = The object invoked has disconnected from its clients.

----> $IEComErrorDescription =

----> $IEComErrorSource =

----> $IEComErrorHelpFile =

----> $IEComErrorHelpContext =

----> $IEComErrorLastDllError = 0

Thanks big daddy.

One last thing, can I change my "If @error <> 0 " to be able to catch the com error?

Yes, @error get set to the global constant $_IEStatus_ComError

Also, look at the console output... all of those $IEComError* are global variables that you can examine the value of after a COM error.
