Thanks Ben & Franck for your help. Like you Franck
I couldn't see why
it would work to cast one completely unrelated thing to another but
this is the way it appeared to be being done in the samples.
Of course, what I hadn't got to grips with is that the two samples
that I was studying are both using RemoteObject rather than WebService
calls and consequently are returning something that can be cast...
Thanks...
