Re : Issues regarding to Client class

Hello,

I've already written as you suggest, but Client class doesn't throw an exception. Indeed, the application freezes for a few seconds and afterwards I get an answer at the command prompt showing that there is no connection to the webserver.

This is my code (just a modification of the Client class example):

1. /**
    * HTTP Client.
    *
    * Starts a network client that connects to a server on port 80,
    * sends an HTTP 1.0 GET request, and prints the results.
    *
    * Note that this code is not necessary for simple HTTP GET request:
    * Simply calling loadStrings("http://www.processing.org") would do
    * the same thing as (and more efficiently than) this example.
    * This example is for people who might want to do something more
    * complicated later.
    */
   
   
   import processing.net.*;
   // import processing.xml.*;
   
   XML xml;
   Client c;
   String data;
   
   void setup() {
     size(200, 200);
     background(50);
     fill(200);
     try {
       c = new Client(this, "192.168.1.41", 8081); // Connect to server on port 8081
     }
     catch(Exception e) {
       // an exception was thrown so decide what to do with it
       String className =  e.getClass().getSimpleName();
       println("Name of exception class: " + className);
       println("Not available");
     }
   }
   
   void draw() {
     if (c.available() > 0) { // If there's incoming data from the client...
       data = c.readString(); // ...then grab it and print it
       println(data);
     }
   }
   

and I get this at the terminal:

I would like:

1) Avoid that my application freezes while waiting for an answer;
2) Adjust the connection time to any value;
3) Let the application know that there is a connection problem.

Thanks in advance!
