Do you mean that the AddNewConnectSession() method doesn't return, or that it
does return but you don't get any connection-completed or connection-failed
events=3F
(I'll assume the latter below)

As Monni mentioned, the easiest way is to set a timer, and if the timer times
out
before you get a connected-event, you can Reset() the MessageTransceiverThread
and get rid of it. Qt's QTimer class works well for this, or if you aren't
using Qt,
you could obtain a similar effect by subclassing ThreadWorkerSession and
overridding
GetPulseTime(), Pulse() and AsyncConnectCompleted() to cause the session to
self-destruct if too much time passes before the connect succeeds.
