RE: task cancellation

Question

Hi,
In addition to previous, you can create a start method from non-window
class, which is going to be your main task, which would start your
windows and non-windows tasks, so if you close one of the windows it will
not affect rest of tasks. So far it works for me very well.
Hope this helps.

Hi,
Task cancellation is a very neat way of exiting cleanly. Infact you can
set the EnableSystemCancel of the TaskHandle class to FALSE, if you don't
want to be cancelled in certain portions of the code. But you should make
sure you reset it to TRUE.
One complexity that gets added is maintaining a list of
EventRegistration and TaskDesc objects for each of the tasks that you
have started and registering and deregistering for the task completion
event registrations dynamically. But it is definitely worth the effort.

Mark,
In the started long-running task, you can catch the CancelException and
do
nothing with it.
For example,
EXCEPTION
when e:CancelException do
// do nothing
From Forte Help:Fort? raises an exception of the CancelException class primarily by
invoking the SetCancel method of the TaskDesc class. A task within an
application can signal another task within the same application to cancel
itself. In a few cases the system generates the signal.
For further discussion, see Using CancelException.
Hope this helps,

Subject: Asychronous tasks
I have a window that starts a number of asychronous tasks. One of
these tasks in particular can take a long time (1-2 minutes) to complete
depending on the current data in the workflow. If the user closes the
window before this tasks completes I get the following message:
USER ERROR: The Shutdown event was post on the task. The task is
not registered for the event and is therefore cancelled.
I have put taskDesc objects on all the asychronously started tasks and in
the task.Shutdown event of the window I, after checking to make sure
the handle isn't NIL, issue a
taskDesc.PostShutdown(SH_TP_TASKANDCHILDREN). This seemed to
clear up the problem.
However this window is called from a higher level menu in the
application. When control is returned to this higher window and the user
closes it, they same shutdown error occurs. I have tried capturing the
task handle of the called window and issuing the PostShutdown there
also, but with no luck.
What am I missing?
TIA,
Mark Nichols
