Hi,
I'm completely stuck with some example code I'm trying to use. The code
is from
I would have thought to create a new 'PingExample' object the correct
syntax would be,
PingExample ping = new PingExample("si mon.heber.ltd") ;
as the class is expecting a string as an argument.
I get the following error though:
No overload for method 'PingExample' takes '1' arguments
Thanks for any help,
Simon Porter
