Power Point on Panel

Question

I tried to work on the the 3rd answer. Check the link : http://go4answers.webhost4life.com/Example/start-powerpoint-runslideshow-mode-ole-79033.aspx

But I cant get it work. I guess there are missing codes. I wrote the codes one by one but it's still not working. I am sorry but I am not that familiar with C#. Could you help me out?
