New Post: return a value from an .exe to a task

i took a look at the interface "ITaskHandler" and it has only these methods:

-Pause: Called to pause the COM handler.
-Resume: Called to restart the COM handler.
-Start: Required. Called to start the COM handler.
-Stop: Required. Called to stop the COM handler.

i would need something that should be fired continuously, a sort of "notify" event.
Do you think is it possible using any "workaround" to simulate this behaviour?
any ideas?
