For a Microsoft PowerPoint 97 version of this article, see 171383.



SYMPTOMS
When you run a Microsoft Visual Basic for Applications macro or procedure that cycles through one or more Microsoft Graph object in Microsoft PowerPoint, the Windows 95 Close Program dialog box (or the Windows NT Task Manager) shows that a separate process for each graph remains after the procedure ends. For example, if you have a procedure that cycles through all three graphs in a presentation, three copies of Graph9.exe remain running after the procedure ends.



CAUSE
When you activate a Graph object, PowerPoint creates a persistent data pointer (IDispatch interface pointer) to the Graph object. The persistent data pointer allows quick access to the Graph object in case it is needed again. PowerPoint releases the pointer when the presentation is closed, and Graph unloads itself from memory.



WORKAROUND
To work around this problem, close and then reopen the presentation that contains the Graph objects that were edited.

Method 1: Manually Close the Presentation

 * 1) On the File menu, click Close.

This process removes any Graph objects from memory that are associated with the presentation.
 * 1) On the File menu, click Open. Open the presentation you just closed; no Graph objects are activated yet.

Method 2: Use a Visual Basic Macro to Close the Presentation

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. NOTE: The following macro examples work only in PowerPoint. Visual Basic for Applications macros are not supported by the Microsoft PowerPoint Viewer. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: The sample code assumes the following:
 * The presentation that contains the Graph objects is the active presentation. -and-


 * You are running this procedure from a presentation that is not the active presentation. For example, if you run this code from the presentation that you are trying to close, the procedure ends after the ActivePresentation.Close statement, because you just closed the presentation that contains the code.

Sample Visual Basic Procedure
Sub ReloadPresentation

Dim strPresPathName As String Dim lCurrentView As Long Dim lSlideNumber As Long

' Determine what view the presentation is in. lCurrentView = ActiveWindow.ViewType

' If the active view is slide view, get ' the slide number. If ActiveWindow.ViewType = ppViewSlide Then lSlideNumber = ActiveWindow.View.Slide.SlideNumber End If

' Save the presentation, if needed. If ActivePresentation.Saved = msoFalse Then ActivePresentation.Save End If

' Get the name and path to the active presentation. strPresPathName = ActivePresentation.FullName

' Close the presentation. ActivePresentation.Close

' Reopen the presentation. Presentations.Open strPresPathName

' Restore the view. ActiveWindow.ViewType = lCurrentView

' If in slide view, restore the slide number. If ActiveWindow.ViewType = ppViewSlide Then ActiveWindow.View.GotoSlide lSlideNumber End If

End Sub

Method 3
Insert the following line of code when you want the Graph program to quit: oGraph.Application.Quit This command will differ, depending upon your macro.
