Hi Ziq,
You may be able to do this with notifiers/queues, but if it all possible you would want to launch the CVI application from TestStand and pass the context as one of the parameters, though that may not be an option for you. If you could explain why you are wanting to do this as well as the overall structure of your application there will probably be a superior way to do this based on that info.
