Hi Craig,

I have a clear description of delegates now and use them extensively. I just had a hard time becuase everything I read used different naming for the different pieces which made it really hard to follow and figure out.
This is my naming: This makes it clear for me although not consistent with everyone else.

public delegate void ConnectionStateChangedDelegate(Object sender, ConnectionStateChangedEventArgs e);

public class ConnectionStateChangedEventArgs : EventArgs
{
     public readonly bool IsConnected;
     public readonly string Message;

     public ConnectionStateChangedEventArgs(bool isConnected, string message)
     {
          this.IsConnected = isConnected;
          this.Message = message;
     }
}

/// <summary>
/// Connection State Changed Event
/// </summary>
public event ConnectionStateChangedDelegate ConnectionStateChanged;

/// <summary>
/// Raises the Connection State Changed Event
/// </summary>
private void OnConnectionStateChanged(bool connectState)
{
     this._connected = connectState;
     string message = "Disconnected!";

     ConnectionStateChangedDelegate csc = this.ConnectionStateChanged;
     if (csc != null)
     {
          if (this._connected)
          message = "Connected on " + gps.PortName;

          // Raise the event
          this.ConnectionStateChanged(this, new ConnectionStateChangedEventArgs(this._connected, message));
     }
}
