Automation creating PowerPoint Presentation problem

[kevininstructor]

I found a good example at Microsoft but appear to have some slight problems.

Example @ Microsoft
http://support.microsoft.com/default...b;EN-US;303717

Note:I followed all the instructions

Directly under
'Build Slide #3:

DotNet is not recognizing
Office.MsoPresetTextEffect.msoTextEffect27

May be due to the fact I can not get DotNet to accept
Imports PowerPoint = Microsoft.Office.Interop.PowerPoint
or
Imports Graph = Microsoft.Office.Interop.Graph

Basic error message is
"NameSpace or type 'powerpoint' for the Imports
'Microsoft.Office.Interop.PowerPoint' can not be found"

If I cut out the code building the third slide all works fine.
Any thoughts/suggestions?
Thanks in advance
Kevin
