SYMPTOMS

When you use the CreateObject function, which is used to control the Microsoft PowerPoint object model from Microsoft Visual Basic for Applications code, you may notice the following behavior:

If PowerPoint is running, a new instance of PowerPoint is not created.
If PowerPoint is not running, a new instance is created.

This behavior is normal.

CAUSE

PowerPoint is a single-session program. CreateObject cannot create a new instance of PowerPoint, if it is already running. This behavior is similar to the Visual Basic GetObject function.

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 CreateObject function creates new instances of multiple session programs. Microsoft Word is an example of a multiple-session program. The following code sample creates two sessions of Word.

   Sub TwoWordSessions()

      Dim word(2) As Object
      Dim i As Byte

      For i = 1 To 2
         ' Call CreateObject.
         <Set word(i) = CreateObject("PowerPoint.Application")>

         ' Make Word visible.
         word(i).Visible = True

      Next i

   End Sub

The same code used with PowerPoint launches one session at most.

NOTE: To use this code with PowerPoint, you must change the string passed to CreateObject. The following code is an example of this:

   Set word(i) = CreateObject("PowerPoint.Application.8")
