PowerPoint COM event handler initialization error

Recommended Posts

DHL

Hi, I'm getting this error while trying to initialize a com event handler for Office PowerPoint events. The PowerPoint file is displayed correctly, but no events are captured as the ObjEvent() fails :

err.number is: -2147316576
err.windescription: Type mismatch.

err.description is:
err.source is:
err.helpfile is:
err.helpcontext is: 0
err.lastdllerror is: 0
err.scriptline is: 23
err.retcode is: 0

The sourcecode is:

Local $oMyError = ObjEvent("AutoIt.Error","MyErrFunc") ; Initialize a COM error handler
Func MyErrFunc($oError)
ConsoleWrite("err.number is: " & @TAB & $oError.number & @CRLF & _
         "err.windescription:" & @TAB & $oError.windescription & @CRLF & _
         "err.description is: " & @TAB & $oError.description & @CRLF & _
         "err.source is: " & @TAB & $oError.source & @CRLF & _
         "err.helpfile is: " & @TAB & $oError.helpfile & @CRLF & _
         "err.helpcontext is: " & @TAB & $oError.helpcontext & @CRLF & _
         "err.lastdllerror is: " & @TAB & $oError.lastdllerror & @CRLF & _
         "err.scriptline is: " & @TAB & $oError.scriptline & @CRLF & _
         "err.retcode is: " & @TAB & $oError.retcode & @CRLF & @CRLF)
EndFunc
Local $AppPowerPoint = ObjCreate("PowerPoint.Application")
If Not IsObj($AppPowerPoint) Then
MsgBox(0, "Error", "$AppPowerPoint is not an Object.")
Else
MsgBox(0, "Error", "Successfully created Object $AppPowerPoint.")
EndIf
Local $pptEvt = ObjEvent($AppPowerPoint, "PowerPointEvent_") ; Initialize PowerPoint COM event handlers
Local $OpenPresentation = $AppPowerPoint.Presentations.Open("C:\Users\DagHendrik\Desktop\test.ppt",True, False, False)
$OpenPresentation.SlideShowSettings.ShowPresenterView = 0
$OpenPresentation.SlideShowSettings.ShowType = 1
Local $SlideShowWindow = $OpenPresentation.SlideShowSettings.Run()
While True
Sleep(10)
WEnd

Func PowerPointEvent_SlideShowNextSlide($obj)
ConsoleWrite("GetCurrentSlide = " & ($SlideShowwindow.View.Slide.SlideIndex-1) & "<"& @LF)
EndFunc
Func PowerPointEvent_SlideShowOnNext($obj)
ConsoleWrite("GetCurrentSlide = " & ($SlideShowwindow.View.Slide.SlideIndex-1) & "<"& @LF)
EndFunc

The script continues fine, but no event are fired as the line with

Local $pptEvt = ObjEvent($AppPowerPoint, "PowerPointEvent_") ; Initialize PowerPoint COM event handlers
fails.

I'm using the latest autoit (v3.3.8.1, 32 bit) And I'm running Office PowerPoint 2013 32bit on a Windows 8 Pro 64 bit installation.

Any idea why the ObjEvent() fails?

(EDIT: changed to autoit code formatting)

But doesn't the error happen on line 23 which is "Local $SlideShowWindow = $OpenPresentation.SlideShowSettings.Run()"?

I think some of the formatting got lost when I copy-pasted the code. The error happens on the line

Local $pptEvt = ObjEvent($AppPowerPoint, "PowerPointEvent_") ; Initialize PowerPoint COM event handlers

The application and presentation loads fine, but because the event handler initialization failed I don't get any events back when advance through the slides

I tried here (AutoIt 3.3.8.1, Windows 7 64 bit, Office 2010 32 bit) and get the same error. But I can't see anything wrong.

I will check again after I had my coffee ;)

Seems to be a problem with PowerPoint. As soon as I replace "PowerPoint.Application" with "Outlook.Application" or "Excel.Application" the error is gone.

Needs some more investigation ...

I tried the code with AutoIT 3.3.6.1 and then it worked fine!

Seems like something has changed for the worse in AutoIt 3.3.8.1. Any idea?

Some changes have been made to COM (error handling) since 3.3.6.1.

IIRC the Devs made some notes that COM support was somehow broken before 3.3.8.1. They fixed it and performance dropped a bit and maybe the problem you see has been caused by this changes too.

Could you please download the latest beta version (3.3.9.4) and try again. The latest beta has seen some changes in the COM area again. The beta can be installed in parallel to the production version.

Sorry, then I have run out of ideas <_<

You can either open an error ticket on Trac or stay with 3.3.6.1

      I was Playing around With AutoIt this evening and wondered how hard it would be to get typeinfo like the COM Viewers do only using AutoIt
      Turns out it was pretty easy.
      A Few Notes:
      CAarray info is unfinished I didn't have any objects to test it on so I left it Limited.
      The Object must have IDispatch exposed (ITypeInfo is derivative)
      Its Just a proof of concept Run with it but don't carry scissors
      ITypeInfoCOM.au3
      ITypeInfoTest.au3

       Hello all"
      I have curious problem with com object implementation of Sapi 5.1.
      In some cases }Some Voice engines] the metods for retrieve the voice parameters fails with error :Member not exists:.
      But the Retrieved Voice object can speak the given text, so It exists and work.
      Example of this type of Engine can be this one: http://download.kobavision.be/KobaSpeech3/KobaSpeech 3 With Vocalizer Serena - English (Great Britain).exe (can work as demo)
      So my question is> Is there some way to workaround or solve this issue?
      What i tryed:
      1. Typical use of Sapi.spvoice object:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
       
        $spvoice = ObjCreate("sapi.spvoice")
      for $voice in $spvoice.getvoices()
        msgbox(0, "Voice", $voice.getdescription())
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc

      2. Implement workaround based on Nvda Screen reader sapi5 Library at https://github.com/nvaccess/nvda/blob/master/source/synthDrivers/sapi5.py
      Thys code in Pascal should work, so i tryed to reproduce it in Autoit.
      Pascal code just as example:
                   SOTokens:=SpVoice.GetVoices('','');
                   for i:=0 to SOTokens.Count-1 do
                   try
                        SOToken:=SOTokens.Item(I); s:=SOToken.GetDescription(0);
      end
      In Autoit I tryed it like this:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
        $spvoice = ObjCreate("sapi.spvoice")
      for $i = 0 to $spvoice.getvoices.count-1
      $name = $spvoice.getvoices.item($i).getdescription
      msgbox(0,"Voice", $name)
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc
      Both of this methods returning same Error ("Member not exists.").
      Thanks a lot for help.

      Hello,
       
      Is there a way to get all the properties and method of a COM object thru Autoit.
      I am looking in a way of display the imbricated structure of object and method.
       
      Example of COm objects are "itunes.application", "Shell.application" and so on.
      The idea is to have a code looking like
      $objtobrowse = objcreate("itunes.application") if isobj($objtobrowse) then $colItems = $objtobrowse.buildinproperty For $objItem In $colItems ConsoleWrite($objItem.<Name> & " - " & $objItem.<Value> & @CRLF) Next EndIf
