Thanks for your informative answer!
But in the articles the cancel is called inside of the task, of course, the exception will be throw by the task thread, and if you call the cancel() by click button, the exception will be throw in _cancel.Cancel()(main thread).
As you said, every thread has an exception stack(if I understand correctly),and exception will be "created" in the thread who raise it right, it seems like there is no way one thread can throw an exception in the other thread except abort the other thread directly.
Maybe I can implement it like this:
Task.Run(() =>
{
try
{
var currentThread = Thread.CurrentThread;
_cancel.Token.Register(currentThread.Abort);
DoWork();
}
catch (Exception)
{
throw;
}
})

I think this solution is not suitable for my problem, this solution can handle the case that task will throw the exception by himself. what I want is there is a long running operation in the task, and user wants to cancel this task by clicking the button like a trigger, it is better to throw an exception from the task after cancel token is notified that it is canceled, cause I want to do the clean up staff outside.

Windows service does work, I found I need run the Windows service first,and then add the Service References in the client project.

No,I do it all on the code,as the SQL CE does not support the stored procedures

eric881027 25-Jul-11 2:04am View

Yeah,I am working by this way.

But I have to use the SQL CE,it does not support trigger.

eric881027 25-Jul-11 1:32am View

Yeah,this is what I am thinking about.Do you have any experience about that,what need be paid attention to?

I'm sorry, I didn't make it clear, I mean messages for the underlying transport.

Ok,thanks,do you think the Service Broker can handle this effect?

Thanks,locking the database is also a good solution,my point is how the database tell users who is editing the data,or the app has to read the database all the time to get this information.

eric881027 11-Jul-11 22:03pm View

Yeah,I thought about that,by this way the app have to read the data all the time.I want the database takes the initiative to send a message to the app.
