I have made an OLE object in a form named "frmPresentatie", I managed to load a powerpoint presentation into the object (using OLE because Powerpoint components aren't available for free)

I load the presentation using the following code:

Code:
With frmPresentatie.objPP
    .Left = 0
    .Top = 0
    .Width = 1
    .Height = 1
    .OLETypeAllowed = acOLELinked
    .SourceDoc = bestandsnaam
    .Action = acOLECreateLink
    End With
Now I'm having difficulties navigating through the slides. I'd like to get the number of slides and find a way to go to the next/previous slide.

I've tried many things already as ".SourceItem = FIRSTSLIDE", "debug.print objPP.Slides(i).SlideID".. but nothing seems to work..

Can anyone help me out with this? I'd really appreciate..
