Powerpoint presentation in windows form

Question

Is it possible to show an Powerpoint presentation in a windows form?

Or is there any way to run a program (visual) in an windows form?

Found the code in VB 5. http://skp.mvps.org/vb/pptvbwnd.htm

Anybody who knows where to find C# code for this? or is there sombody who can convert this code quickly?
