I'll have to go digging around for code, but here's a way using ECP:
 
Change your OnAppInit() to:
 
First send an ECP command of your own design
(with CascadeInput::DispatchECPCommand()) and examine the reply.
If the ecp command is handled, you know your app was running and
materialized itself again, you can then call Terminate(0) in that instance
and return from OnAppInit().
 
If the ECP command was not handled, then your app didn't do its thing,
and you may proceed with normal initialization.  You'll simply add
a call to RegisterECPCommand() in OnAppInit at that point to register
your new ECP Command.
 
Then add yourself an OnECPCommand() virtual member function that
will examine the request, determine what
state it is in, materialize itself if required, then set the reply string
so that the calling app knows what happened.
