How do I hit a web page from within a button handler in my Windows Forms application

Use the Process class found in the System.Diagnostics namespace.

	Process proc = new Process();
	proc.StartInfo.UseShellExecute = true;
	proc.StartInfo.FileName = @'http://www.microsoft.com';
	proc.Start();
	
	// or just put it all as one statement
	//System.Diagnostics.Process.Start(@'http://www.microsoft.com');
