Hi,

Dont know if this may sound too complex, but here is what I would have done (offcourse only if i had known windows programming )

you can have your solaris application open a socket and listen on a port and a socket on windows that would write to this port after completion of the job, thus notifying it. once the solaris socket gets this info it can then continue with what you want it to continue with

I can tell you further on the unix side of this, for windows please spare me !!

Warm
Regards
