By "off" do you mean logged out or disabled?

  Do you mean that if the session is off, the message will only be =
stored locally and the seq number will be increased? Next time the =
session is created, the counterparty will figure out the seq # does not =
match and therefore will ask for resend.=20

  If that is the case, that  makes sense. However, I feel not =
comfortable assuming the message has been pushed out without any warning =
or exception. Should program be notified if it tries to send a message =
when the session is off?=20

  Thanks=20

  And you never will know.  FIX is an asynchronous protocol.  There is =
no way for it to indicate the succesful receipt of a message.  That is =
why the sequence numbers are necessary.  Your SendToTarget is returning =
true because QuickFIX was able to store your message and take =
responsibility for sending it.  It may not be able to send it right =
away, but it will do so when required by a ResendRequest.=20

  A related question:=20

  It seems that I can use the static method =
Session.sendToTarget(Message, SessionID) successfully even when the =
corresponding session is not logged on. (I am not sure if the =
counterparty really receives the message in this case)=20

  I am using the initiator and I'd like to know how I can check if the =
socket
  was dropped. (i.e. if the connection was shut down by the acceptor =
side)

  I figure I can use these properties but I'm not 100% sure what they =
mean:

  session.isEnabled()
  If the session exists, how can it not be enabled?

  session.isLoggedOn()
  socket.isLoggedOn()
  Are they always the same and do they mean the same thing?

  Thanks,

  Francis Gingras
