Hi,
I am not sure what are the "official" rules, but the general idea is
that you need not concern yourself too much with events when you are
in synchronous mode. In synchronous mode, you can be sure that by the
time target.Launch() returns, the process will be stopped (or dead, or
something else, you can check process.GetState() to find that out). No
need to play around with listeners...
cheers,
pl
