@COM_EventObj - why not works in my case ?

I'm trying to use @COM_EventObj 

For this I look in helpfile go to

ObjEvent()

and get first example.

I just add one line:

MsgBox(0, 'ERROR @COM_EventObj', @COM_EventObj)

and here is it:

#include <MsgBoxConstants.au3>

Example()

Func Example()
    ; Error monitoring. This will trap all COM errors while alive.
    ; This particular object is declared as local, meaning after the function returns it will not exist.
    Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

    ; Create Internet Explorer object
    Local $oIE = ObjCreate("InternetExplorer.Application")
    ; Check for errors
    If @error Then Return

    $oIE.Visible = True ; set visibility

    ; Custom sink object
    Local $oIEEvents = ObjEvent($oIE, "_IEEvent_", "DWebBrowserEvents2")

    ; Navigate somewhere
    $oIE.navigate("http://www.google.com/")
    ; Check for errors while loading
    If @error Then
        $oIE.Quit()
        Return
    EndIf

    ; Wait for page to load
    While 1
        If $oIE.readyState = "complete" Or $oIE.readyState = 4 Then ExitLoop
        Sleep(10)
    WEnd

    ; Deliberately cause error by calling non-existing method
    $oIE.PlayMeARockAndRollSong()

    ; Check for errors
    If @error Then MsgBox($MB_SYSTEMMODAL, "COM Error", "@error is set to COM error number." & @CRLF & "@error = 0x" & Hex(@error))

    ; Wait few seconds to see if more events will be fired
    Sleep(3000)

    ; Nothing more to do. Close IE and return from the function
    $oIE.Quit()

    #forceref $oErrorHandler, $oIEEvents
EndFunc   ;==>Example

; BeforeNavigate2 method definition
Func _IEEvent_BeforeNavigate2($oIEpDisp, $sIEURL, $iIEFlags, $sIETargetFrameName, $sIEPostData, $iIEHeaders, $bIECancel)
    MsgBox(0, 'ERROR @COM_EventObj', @COM_EventObj)
    ConsoleWrite("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!--BeforeNavigate2 fired--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! " & @CRLF & _
            "$oIEpDisp = " & $oIEpDisp() & "  -  " & ObjName($oIEpDisp) & @CRLF & _ ; e.g. default property and name for the object
            "$sIEURL = " & $sIEURL & @CRLF & _
            "$iIEFlags = " & $iIEFlags & @CRLF & _
            "$sIETargetFrameName = " & $sIETargetFrameName & @CRLF & _
            "$sIEPostData = " & $sIEPostData & @CRLF & _
            "$iIEHeaders = " & $iIEHeaders & @CRLF & _
            "$bIECancel = " & $bIECancel & @CRLF & _
            "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! " & @CRLF & @CRLF)
EndFunc   ;==>_IEEvent_BeforeNavigate2

; User's COM error function. Will be called if COM error occurs
Func _ErrFunc($oError)
    ; Do anything here.
    ConsoleWrite(@ScriptName & " (" & $oError.scriptline & ") : ==> COM Error intercepted !" & @CRLF & _
            @TAB & "err.number is: " & @TAB & @TAB & "0x" & Hex($oError.number) & @CRLF & _
            @TAB & "err.windescription:" & @TAB & $oError.windescription & @CRLF & _
            @TAB & "err.description is: " & @TAB & $oError.description & @CRLF & _
            @TAB & "err.source is: " & @TAB & @TAB & $oError.source & @CRLF & _
            @TAB & "err.helpfile is: " & @TAB & $oError.helpfile & @CRLF & _
            @TAB & "err.helpcontext is: " & @TAB & $oError.helpcontext & @CRLF & _
            @TAB & "err.lastdllerror is: " & @TAB & $oError.lastdllerror & @CRLF & _
            @TAB & "err.scriptline is: " & @TAB & $oError.scriptline & @CRLF & _
            @TAB & "err.retcode is: " & @TAB & "0x" & Hex($oError.retcode) & @CRLF & @CRLF)
EndFunc   ;==>_ErrFunc

 

So I'm wondering why this wont work for me ?

What I'm doing wrong ?

EDIT:

I just want to write that I expected that MsgBox show me the "InternetExplorer.Application" name as @COM_EventObj

but then I realize that the solution is:

Local $oObject = @COM_EventObj
    MsgBox(0, 'ERROR @COM_EventObj', ObjName($oObject,1))

 

sorry for bothering .
