A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
You could use that method (I wrote that page) like this maybe:
Sub OnSlideshowPageChange(SW As SlideShowWindow)
Dim osld As Slide
Dim oshp As Shape
Dim oMWB As Object
Set osld = SW.View.Slide
For Each oshp In osld.Shapes
If oshp.Type = msoOLEControlObject Then
If oshp.OLEFormat.ProgID = "Shell.Explorer.2" Then _
Set oMWB = oshp.OLEFormat.Object
Exit For
End If
Next
If Not oMWB Is Nothing Then _
oMWB.Navigate ("Http:\www.google.com")
End Sub
