TAPI COM EVENT Hadling - Type mismatch 0x80028CA0 - ITTAPIEventNotification

6 posts in this topic

Hallo,

first of all, kind regards to all of you :D

I have a problem where I cound't figure out what I'm doing wrong:

Currently I'm writting on a program for Incomming Calls via TAPI which should be registred in a list.
As you can see the registration via the RegisterCallNotifications() function works fine (after calling I get an RegToken).

But I don't understand why I get the following type mismatch com error:

notify.au3 (57) : ==> COM Error intercepted !
err.number is: 0x80028CA0
err.windescription: Typenkonflikt.


err.description is:
err.source is:
err.helpfile is:
err.helpcontext is:
err.lastdllerror is: 0
err.scriptline is: 57
err.retcode is: 0x00000000

I tried also to add parameters to the fuction ITTAPIEventNotification.Event() as described on MSDN:
HRESULT Event( [in] TAPI_EVENT TapiEvent, [in] IDispatch *pEvent);

Without any success.:( What is wrong ....
I really don't know what to do ?(?(?( !!!


Here is my code:

$custom_number = 418
$txtAddressName = "Alice Line  SIP 418"

Global Const $LINEADDRESSTYPE_PHONENUMBER = "&H1"
Global Const $LINEMEDIAMODE_INTERACTIVEVOICE = "&H4"
Global Const $TAPI3_ALL_TAPI_EVENTS = "&H1FFFF"

Global Const $fOwner = True         ; ensures that the application receives incoming calls and their call state events
Global Const $fMonitor = True       ; Boolean value indicating whether the application will own incoming calls. TRUE indicates that the application will own incoming
                                    ;calls; FALSE indicates that it will not.
Global Const $lMediaTypes = "&H8"; 8
Global Const $lCallbackInstance = "&H1"; 1

Global $regToken
Global $gobjAddress
Global $objTapi
Global $objTapiEvent
Global $objTapiWithEvents

Global $oErrorHandler

; objTapi.RegisterCallNotifications( [in] ITAddress* pAddress, [in] VARIANT_BOOL fMonitor, [in] VARIANT_BOOL fOwner, [in] long lMediaTypes, [in] long lCallbackInstance )
;~  _add_CallToList($custom_number)

    Local  $lAddressType = $LINEADDRESSTYPE_PHONENUMBER
    Global $bolFoundLine

    $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

    $objTapi = ObjCreate("TAPI.TAPI")
    $mapper = ObjCreate("DispatchMapper.DispatchMapper.1")

    $objTapi.Initialize
    $objTapi.EventFilter = $TAPI3_ALL_TAPI_EVENTS


    $objCollAddresses = $objTapi.Addresses
    For $lLoop = 1 To $objCollAddresses.Count
        $objCrtAddress = $objCollAddresses.Item($lLoop)
        If $objCrtAddress.AddressName = $txtAddressName Then
            $gobjAddress = $objCrtAddress
            $bolFoundLine = True
            ExitLoop
        EndIf
    Next


    If $bolFoundLine = True Then
        $objTapiWithEvents = $objTapi
        $regToken = $objTapiWithEvents.RegisterCallNotifications($gobjAddress, $fMonitor, $fOwner, $lMediaTypes, $lCallbackInstance)
        If @error Then ConsoleWrite("Es gab einen Fehler bei $regToken" & @CRLF)
        ConsoleWrite("########## RegTokken: ->" & $regToken & "<- #########################" & @CRLF)

        Sleep(3000) ; zeit geben zum Initialisieren der RegisterCallNotifications Methode

;~      ConsoleWrite(VarGetType($objTapiWithEvents) & @CRLF)
        Local $test = ObjEvent($objTapi, "_TapiEvent_", "ITTAPIEventNotification")
        If @error Then ConsoleWrite("Es gab einen Fehler bei objEvent" & @CRLF)
        ConsoleWrite("$test ='" & $test & "'" & @CRLF)

        ConsoleWrite("blub" & @CRLF)
    EndIf

    While 1
        Sleep(100)
    WEnd


; Event method definition
Func _TapiEvent_ITTAPIEventNotification();($Tapi_Event, $IDispatch)
    ConsoleWrite("event geht ein!!!!" & @CRLF)
    Local $ret = "&H0"
    return $ret
EndFunc


    ; 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

I would be very happy about every sugguestion to solve this problem.

Last but not least, bear with me I am not a native english speaker:sweating:

Anybody an idea?

I really don't know what is wrong with the code...:blink:

Is a COM-Specialist out there???

This is a very important project for me. I would be very grateful for any idea:)

PS: If I posted this Item under the wrong topic, please tell me or move it to the right place.

Thx

Never used it before.
Give some URL links to reference for this two objectes:

$objTapi = ObjCreate("TAPI.TAPI")
$mapper = ObjCreate("DispatchMapper.DispatchMapper.1")

 

 

EDIT:

 
Global Const $LINEADDRESSTYPE_PHONENUMBER = "&H1"
Global Const $LINEMEDIAMODE_INTERACTIVEVOICE = "&H4"
Global Const $TAPI3_ALL_TAPI_EVENTS = "&H1FFFF"

Global Const $fOwner = True         ; ensures that the application receives incoming calls and their call state events
Global Const $fMonitor = True       ; Boolean value indicating whether the application will own incoming calls. TRUE indicates that the application will own incoming
                                    ;calls; FALSE indicates that it will not.
Global Const $lMediaTypes = "&H8"; 8
Global Const $lCallbackInstance = "&H1"; 1
You are declaring const in wrong way
try this:
Global Const $LINEADDRESSTYPE_PHONENUMBER = 0x1
Global Const $LINEMEDIAMODE_INTERACTIVEVOICE = 0x4
Global Const $TAPI3_ALL_TAPI_EVENTS = 0x1FFFF

Global Const $fOwner = True         ; ensures that the application receives incoming calls and their call state events
Global Const $fMonitor = True       ; Boolean value indicating whether the application will own incoming calls. TRUE indicates that the application will own incoming
                                    ;calls; FALSE indicates that it will not.
Global Const $lMediaTypes = 0x8; 8
Global Const $lCallbackInstance = 0x1
