PPT Crashes on Dual Monitor.

[Guest]

I am working on PowerPoint Automation.

I have an external application that runs PowerPoint slideshow. When I run my
app it creates a ~temp.ppt file as a copy of the active ppt and runs the
slideshow for that. I have been able to trap the events. On "SlideShowEnd" I
am closing this ~temp.ppt file:
Sub PPTEVENTS_SlideShowEnd(Pres as Presentation)
if Pres.Name="~temp.ppt" then
Pres.Close
Endif
End Sub

This works fine for single monitor. But, when I do this for dual monitor
(with Presenter view enabled) I get PowerPoint crash error message when the
line Pres.Close is executed. I am not sure what is happening in Dual Monitor
that makes PPT crash while executing this line. I searched on the net and got
an article related to corrupted VBE6.dll file but that didn't helped me.
One more thing I observed was if I click "End Show" button on the presenter
view then it closes the ~temp.ppt file without any error message.

Can anyone tell me what could be the possible reason for this? This is
really urgent.

Thanks a lot in advance.

Instead of closing the presentation in the SlideShowEnd event handler, try
closing it in your application's main thread through the message loop.
Basically, post a user message in the SlideShowEnd event handler and write
the user message handler that closes the presentation. This way, you will
use the automation interfaces in the same thread that started PowerPoint.

Let me know if this helps.

I changed the code such that I am not closing the Presentation in the
SlideShowEnd event sub. I am not calling a function in the SlideShowEnd which
is present in my external application.
--------------------------------------------------
Sub PPTEVENT_SlideShowEnd(Pres as Presentation)
Set objMyApp = CreateObject("MyApp.clsMyApp")
Call objMyApp.SlideShowClose
End Sub
---------------------------------------------
And in my external App (which I am implementing as a dll) I have written
App_.ActivePresentation.Close where App_=PowerPoint.Application, in the
subroutine SlideShowClose().

But, I am still getting the PowerPoint crash message whenever PPT close code
is executed.

Any suggestions?

Thanks.

Its the same thing whether you try to close the presentation in VBA or
through an external DLL. Try the solution that I suggested earlier. Use
PostMessage() Windows API and post a WM_USER message to your application's
main window. Close the presentation in the handler for WM_USER message.
