CreateObject does not create new PowerPoint session
This article was previously published under Q222783
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.
MORE INFORMATION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. 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 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")
