A try/catch maybe...

try / catch doesn't work with loadStrings()...
Check if the returned value is null, instead.

Hi Guys,

Thanks for the suggestions

I have tried it with the following code in my serialEvent() function

1. try
   
2. {
   
3.                   URL url= new URL(UpdateURL);
4.                   URLConnection connection = url.openConnection();
5.                   connection.setRequestProperty("User-Agent", "I am a real browser like Mozilla or MSIE" );
6.                   String[] results = loadStrings(connection.getInputStream());
7.                   println(results);
8. }
9.                   catch (Exception e)                                                   // MalformedURL, IO
10. {
11.                   println("HTTP Error");
12.                   e.printStackTrace();
13. }

which works nicely, however I am looking for a more elegant solution. Especially as I am trying to keep this free of imported libraries. So I tried the following which sort of works but doesnt give the expected output

1. String[] result = loadStrings(UpdateURL);
   
2. if (result == null);
   {
3.                   println("Network communications error ");
4. }
5. 
   
6. if (result != null);
7. {
8.                   println("Server response "+ result[0]);
9. }

 
For output on every line I get

Network communications error
Server response e.g 2091

I don't understand where I am going wrong. I thought it would just show Network communications error when there was an error and the result of the loadstrings i.e the number when it worked.

But I get both

Stupid me,

did you notice the ; on the end of each if statement!

Sorry :-(
