PPT97: PowerPoint 97 Remains in Memory After Getting a Presentation and Being Closed

Article ID: 249169

Article Last Modified on 10/11/2006



APPLIES TO

  • Microsoft PowerPoint 97 Standard Edition



This article was previously published under Q249169


SYMPTOMS

If you use the GetObject or CreateObject method to open a presentation programmatically, Microsoft PowerPoint remains running in memory after you quit PowerPoint using any of the following methods:

Sub TestPP()
    Dim oPres As PowerPoint.Presentation
    Set oPres = GetObject("c:\test.ppt")
    Set oPres = Nothing
End Sub
                

-or-


Sub TestPP()
    Dim oPres As PowerPoint.Presentation
    Dim oApp As PowerPoint.Application
    
    Set oPres = GetObject("c:\test.ppt")
    Set oApp = oPres.Application
    
    oPres.Close
    Set oPres = Nothing
    
    oApp.Quit
    Set oApp = Nothing
End Sub
                

-or-


Sub TestPP()
    Dim oPPT As PowerPoint.Application
    Set oPPT = CreateObject("PowerPoint.Application.8")

    oPPT.Activate
    oPPT.Presentations.Open ("c:\test.ppt")
    
    oPPT.Presentations(1).Close
    Set oPPT = Nothing
End Sub
                

After any of the above code segments runs, if you check the Task Manager, it shows that PowerPoint is still loaded into memory.

CAUSE

When using the GetObject("pathname") method (where pathname is the path and name of the presentation you are trying to load programmatically), or the CreateObject("PowerPoint.Application.8") method, PowerPoint does not keep an accurate reference count of the number of calls made to it. Therefore it remains in memory, and you cannot access it programmatically to quit it.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
