How do I programmaticall y prevent a service from stopping? I want to
be able to keep my service running (started), under certain conditions,
when a user tries to stop it. I have tried throwing an exception
- from OnStop(): the SCM waits for a long time, reports that the
service didn't respond in a timely fashion and then leaves the status
as stopping.
- from Dispose(): the SCM displays an error dialog with the exception
details and prompts me to select a debugger. If I select 'No' the
service is stopped.
..NET Framework 1.1
MSDE 2003
Windows 2000 SP4
5  17627 
Set the 'CanStop' property of the service to false.

Sorry one thing I didn't notice was that you said you only want to prevent
the service from stopping under certain conditions. If that's the case,
setting the CanStop property to false wouldn't quite suffice.
Here's a further suggestion. Set the CanStop property to false, as above.
But then you will need an application that the user can use to request a
stop. This app would then communicate with your service (via remoting,
perhaps) and if the condition is permitted, stop itself. You should be
able to do this by dynamically setting 'CanStop' to true, then connecting
to yourself with the ServiceControll er class and issuing the 'Stop'
command.
I haven't actually tried it, but I think that would work.
-mdb
Just s quick note - you wouldn't need remoting for controlling the service,
a ServiceControll er's ExecuteCommand method would suffice if you need just a
parameterless command not returning anything

You will have to specify "the specific error" This can be caused by numerous
reasons, insufficient privileges to control the service would be the first
thing to look at.

However - I get an exception thrown saying access denied. If I switch to

Hi,
I am writing a Windows Service in C#. I want to gracefully fail the
"protected override void OnStop()" function. To do this, I first tried
throwing an Exception in the function. However, that left the Service
in a "Stopping" state.
I would like to fail the Service in the OnStop function without putting
the service in the Stopping state. It would be nice if it's still in
the Started state. Is this possible? If so, how?

Hi,
I have two windows services running together. One is the main

service starts and stops the main one (as in you should never start or

On most computers it works great, the updater's onStop() can start and
stop the main service perfectly. On some computers, though, the
updater hangs when it tries to stop the main service. It...
