Events

• Connected - Notifies that a connection has been established.
• Disconnected - Notifies that a connection has been terminated.
• ObjectWaiting - Notifies that there is an object on the stream.
• ObjectComplete - Notifies that an object transfer is complete.
• FileWaiting - Notifies that there is a file on the stream.
• FileComplete - Notifies that a file transfer is complete.

Remarks

• When responding to the events in a form, BeginUpdate may be necessary since the event notifications are made on seperate threads.
• When responding to an event fired by network, use the following in the function (change "FunctionName" to the name of the function):

   if (this.InvokeRequired)
   {
      // Pass the same function to BeginInvoke,
      // but the call would come on the correct
      // thread and InvokeRequired will be false.
      this.BeginInvoke(new EventHandler(FunctionName), 
         new object[] {sender, e});
      return;
   }
