PowerPoint COM event handler initialization error


Recommended Posts

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 ...

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 have started to rewrite the PowerPoint UDF similar to the Word, Excel and Outlook UDF. The new UDF will not be compatible with the existing one.
      I will add examples, documentation, a section in the wiki etc.
      So far the following functions have been coded - more are on the ToDo list.
      _PPT_Open: Open a connection to a running instance of PowerPoint or start a new one _PPT_Close: Close a PowerPoint instance _PPT_PresentationAttach: Attach to an already opened presentation _PPT_PresentationClose: Close a presentation _PPT_PresentationExport: Export one/multiple/all slides as PDF or XPS. _PPT_PresentationExportGraphic: Export one/multiple/all slides in a graphic format. _PPT_PresentationList: Returns a list of currently open presentations (added with version 1.0.0.0 2021-07-20) _PPT_PresentationNew: Create a new presentation _PPT_PresentationOpen: Open an existing presentation _PPT_Print: Print one/multiple/all slides of a presentation (added with version 1.0.0.0 2021-07-20) _PPT_PresentationSave: Save a presentation _PPT_PresentationSaveAs: Save a presentation to another location or with another type _PPT_ShapeDelete: Delete shape(s) (added with version 1.1.0.0) _PPT_SlideAdd: Add slide(s) to a presentation _PPT_SlideCopyMove: Copy, move, duplicate slide(s) _PPT_SlideDelete: Delete slide(s) _PPT_SlideShow: Show a presentation _PPT_TextFindReplace: Find & replace text throughout entire PowerPoint presentation (added with version 1.0.0.0 2021-07-20) Which functions do you want me to add to the UDF?
      ToDo list:
      create slide (JLogan3o13) - Done: _PPT_SlideAdd Apply template to slide (JLogan3o13) - Done: _PPT_SlideAdd Apply theme to slide (JLogan3o13) Cut/Copy/Duplicate/Move/Delete slide(s) (JLogan3o13) - Done: _PPT_SlideCopyMove, _PPT_SlideDelete Export slides (JLogan3o13) - Done: _PPT_PresentationExport Cut/Copy/Duplicate/Move/Delete shape(s) (JLogan3o13): Partially done : _PPT_ShapeDelete (added with version 1.1.0.0) ApplyAnimation, Select, SetDefaultProperties, and zOrder for shape(s) (JLogan3o13) Searching and replacing text (pcjunki) - Done: _PPT_TextFindReplace (added with version 1.0.0.0 2021-07-20) Export slides in a graphic format (JPG, GIF, PNG ...) (UEZ) - Done: _PPT_PresentationExportGraphic The UDF can be downloaded from the download forum.

      First production version of the PowerPoint UDF.
      Some functions are still missing but will be added quite soon.
      If you want to discuss the UDF please post here.
      BTW: If you like this UDF please click the "I like this" button. This tells me where to next put my development effort

      Hello again, i have a code that changes username to favorite, my problem is how to use ObjEvent() function to catch errors, i've red Help File and Forum's Topics but i can't understand too much😐

      Here is a code (I've copied this codes from a user of AutoIt Forum):
       
      $sOldUser = "Administrator" $sNewUser = "Admin" $oUser = ObjGet("WinNT://" & @ComputerName & "/" & $sOldUser & ",user") $oComputer = ObjGet("WinNT://" & @ComputerName) $oNewUser = $oComputer.MoveHere($oUser.ADsPath, $sNewUser) Thanks for your care, I'm new to AutoIt and days should be passed with my coding and practicing to don't bother you :)❤

      Trying to figure out how to do CallByName on AutoIt COM objects due to the lack of being able to set properties within an Execute() statement
      Several Ideas were Tried https://www.autoitscript.com/forum/topic/200129-set-object-properties-with-propertyname-and-value-taken-from-an-array/
      I think this is the best; Patching the vtable of IDispatch so we can intercept a Fake function call ($obj.Au3_CallByName)
      use it like this
      Local $oDictionary = ObjCreate("Scripting.Dictionary") ; EXAMPLE Au3_CallByname_Init() ; (you can optionally provide a classname here but we patch the main Idispatch interface so really no need) $Au3_CallByName = "Add" ; Method we want to call $oDictionary.Au3_CallByName("Test", "Value") Au3_CallByname_Init(False) ; (Not Strictly Needed unhooked on exit) NOTE:  Au3_CallByname_Init() doesn't have to be called at the top of the script, just call it before you need to call by name...
