At the PADNUG meeting last night the question (Lord knows why this always comes up :) on how to make the system "beep" was asked.  Here's two kinds of beeps, and links to some source.

The "PC Beep," including frequency and duration:

using System.Runtime.InteropServices;
class MainClass
{
[DllImport("kernel32.dll")]
public static extern bool Beep(int freq,int duration);

 public static void Main(string[] args)
 {
  Beep(1000,1000);
  Beep(2000,500);
 }
}

The considerably more interesting "MessageBeep" (via BradA) that uses the Wav files that are configured in the Sounds Control Panel.
