[Raghul]

Hi friends,
I am creating a jabber client and a separate class for
dialog is created,So when the roster name is clicked this dialog open
and can continue chat.What I need is I am calling the same class when
reciving the message so that the application goes not responding.People
told me to use threading for this.
Can any one help me in calling the same dialog class using threading...

Thanks in advance
