How do I: Open a web site on click button?

Is this just for your use or do you need to do this for other people that might use a different browser such as Firefox? The following will open the web site using whatever the "default" browser is.

Process process = new Process();

process.StartInfo.UseShellExecute = true;

process.StartInfo.FileName = "http://www.msn.com";

process.Start();
