thread - exception handling

[Miran Cvenkel]

1. do something
2. start thread (which can fail due to exceptions) - practical sample - sending a bunch of mails to bunch of users about whole event(like to all users following this wery forum theme).
3. do something else
4. notifying user that event is executed OK(like saving this post is successful),end,  (thread under 2 still executing)

1,3,4 all ok. How do you log, handle, exceptins that are possible under 2, unless you ignore the fact that mails mybe did not got send ?

Well, it depends what you want to do when an exception occurs. If in thread 2 you want to notify a user interface of e-mails that didn't get sent, and the user interface is part of thread 1's context, then you should simply pass the user interface to thread 2 when you start it, and let thread 2 deal with the user interface itself.
