ObjEvent not executing function

[Basti756]

I'm trying to receive events about incoming calls from a VoIP software (Mitel UC Advanced - in case somebody wants to know). There is a SDK available which consists of one DLL file (TelephonyProxy.dll).

The documentation of the DLL file says the following about the Offering event:

The Listener class captures the telephony events raised by Unified Communicator

[...]

When used as COM class, the class ID is CE21C9EE-6671-4B1C-8B01-D7AA4C52CB6C.

 

Visual Basic example:

Public Class Listener

Offering event in detail:

The Offering event is raised when Unified Communicator receives an incoming call.

 

Visual Basic example:

Public Event Offering As Listener.OfferingEventHandler

Delegation in Visual Basic:

Public Delegate Sub OfferingEventHandler ( _
    name As String, _
    number As String _
)

This is what I produced in AutoIt based on the documentation:

Local $oError = ObjEvent("AutoIt.Error", "nothing")

$oPhone = ObjCreate("{CE21C9EE-6671-4B1C-8B01-D7AA4C52CB6C}")
$oPhoneEvent = ObjEvent($oPhone,"_PhoneEvent_")

MsgBox(0,"isObj",IsObj($oPhone))

While 1
    Sleep(100)
WEnd

Func _PhoneEvent_Offering($name,$number)
    MsgBox(0,"",$name & " " & $number)
EndFunc

The problem is that the function '_PhoneEvent_Offering' is not executed on incoming calls. The object on the other hand is created (returns 1). The DLL's interface fullfills the requirements of AutoIt for working with it as far as I know. The 'oleviewer.exe' shows the IDispatch-interface under 'Telephony.Proxy' (see attached screenshot).

There are other API options in the DLL file, i.e. dialing a number. This works as desired so I bet I'm missing something with the ObjEvent stuff.

Any help is appreciated.

Thanks, Bastian

EDIT:

When using an object to fetch possible errors I always get this on the console:

err.number is:  -2147319785
err.windescription: Field name not defined in the record

Which version of AutoIt do you run?

[Basti756]

I'm currently running 3.3.6.1 because I read something about changes within the COM handling after that version. Before I was using 3.3.8.1. I already tried the latest beta (3.3.9.4) as well.

Are you sure it shouldn't be _PhoneEvent_OnOffering?

Anyway, find script called TLBViewer.au3 in examples and load it with your TelephonyProxy.dll and then post the output here.

No but it doesn't work either.

There is just a message box popping up saying 'No MSFT Typelib inside this file!'.

There is just a message box popping up saying 'No MSFT Typelib inside this file!'.

Then it's defined in some other file (TLB maybe). Try this code to get location:

$oPhone = ObjCreate("{CE21C9EE-6671-4B1C-8B01-D7AA4C52CB6C}")
$sLocation = ObjName($oPhone, 4)

ConsoleWrite($sLocation & @CRLF)
MsgBox(4096, '', $sLocation)

...and then use TLBViewer. You probably need newer AutoIt than 3.3.6.1 for that.

[Basti756]

I updated AutoIt to 3.3.8.1 yesterday. 3.3.6.1 was for testing only.

$sLocation returns an empty string. It seems like flag 4 is not supported by the object. Is there any other way to get this information?

EDIT: ObjName doesn't return an error and flag 1 is returning the object's name.

EDIT2: This is what is being returned by all flags of ObjName:

1: Listener
2:    
3: TelephonyProxy.Listener
4:         
5: C:\Windows\Microsoft.NET\Framework\v4.0.30319\clr.dll
6: {CE21C9EE-6671-4B1C-8B01-D7AA4C52CB6C}
7: {E0268CC5-7852-3125-8442-11F5A837E806}

Aha, that's .NET COM object. Typelib is generated at runtime.

Go back to ole/com object viewer and find definition of the sink object and then post that. In your previous attached picture you weren't  showing any sink method definition.

[Basti756]

Any hint on what I should look for? I've never done anything like that...

EDIT: Maybe the attached screenshot helps altough it shows only slightly more than the previous one.

What's displayed for _Object?

[Basti756]

Hope that helps

[Basti756]

Sorry for bumping this thread but I still can't figure out why my script isn't working

[trancexx]

You are still not providing enough info about interfaces.

...Check @error after ObjEvent() call and check if your $oPhoneEvent is object.

[Basti756]

I didn't get that IsObj() is able to check for exisiting objects on ObjEvent(), altough ObjEvent() creates an object... anyways.

@error from ObjEvent is -2147319785 and (as a result) the object is not created.

-2147319785 means 'Field name not defined in the record'

I'm the author of that part of AutoIt in newer versions so I know when that's error value emitted. Your best shot is to specify third argument for ObjEvent():

$oPhoneEvent = ObjEvent($oPhone,"_PhoneEvent_", "_Listener")
;...

Though I'm not sure what that argument should be in your case. My guess is _Listener.

I'm working on that too. Did you get some evolution?
