How to automate PowerPoint using VB

Microsoft has an article that explains how to automate PowerPoint using VB

For some odd reason they've entitled it How to automate Powerpoint using VB

Here's a quick example:

Sub AutomatePowerPoint()
' This requires that you set a reference to PowerPoint in Tools, References
' You could later change these to As Object to avoid that necessity
Dim oPPTApp As PowerPoint.Application
Dim oPPTPres As PowerPoint.Presentation
Dim sPresentationFile as String

sPresentationFile = "C:\MyFiles\Somefile.PPT"

' Get a reference to PowerPoint app
Set oPPTApp = New PowerPoint.Application
'  set it visible or you may get errors - there are ways around this but they're
'  beyond the scope of this FAQ
oPPTApp.Visible = True
' minimize if you want to hide it:
' oPPTApp.WindowState = ppWindowMinimized

' Open our source PPT file, get a reference to it
Set oPPTPres = oPPTApp.Presentations.Open(sPresentationFile)

With oPPTPres     ' Do stuff ...
' Show the number of slides in the file, for example
msgbox .Slides.Count
End With

' Cleanup
' Close the presentation
oPPTPres.Close
' Quit PPT
oPPTApp.Quit
' Release variables
Set oPPTPres = Nothing
Set oPPTApp = Nothing

End Sub
