Playback a powerpoint presentation

Question: How can I play back a MS Powerpoint presentation in my Delphi application? Answer: One might think that you need to create a Powerpoint OLE object, but there is an easier way. Drop a TWebBrowser component on your form and enjoy the benefits of Internet Explorer - which will without further coding play .PPT files. If the browser version is new enough, it will play back even the Powerpoint animations. var d1, d2, d3, d4: OleVariant; begin WebBrowser1.Navigate('file:///C:\Documents\Sample.ppt', d1, d2, d3, d4); end;
