return a value from an .exe to a task

May 19, 2015 at 11:06 AM
is it possible return a value during the "running" state of scheduled task from an .exe?

A sort of notification (the precentage of completion e.g.)...
Does exist a way to do that in order to get that value into the Task object?

There is not a way to expose anything from an .exe except for the final result code. If you need to expose in-process information, check out the COMHandlerAction which allows you to write custom code that gets run in-process as a COM object to the Task Scheduler. In the Downloads section, there is a project template to help you write one.

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?

You will want to use the ITaskHandlerStatus interface to communicate back.
