Stopping a Windows Service during OnStart()

Hi,

I am implementing a service that connects to an SMS Controller. We are
implementing this using an assembly in the OnStart() method of a Windows
service. This is working fine, however I cannot work out how to get the
service to stop if we cannot connect to the SMSC, if it is down or incorrect
credentials etc. Currently I am using a ServiceController class which I am
calling the stop method of, but this seems to hang and then eventually stop
the service after the timeout.

Is there any way to abort the OnStart method?

Cheers

Dave,

I haven't tried this, but have you thought of throwing an exception?
What happens if you do this?
 
Throwing an exception will stop the service from running ie.

//Service.cs
protected override void OnStart(string[] args) {
Throw throwEx = new Throw();
}

//Throw.cs
public Throw() {
string dummy = null;
dummy.Substring(10, 3);
}


This will throw an "Could not start the service" when the service starts.
Does anyone know of any resources on this kind of thing, all documentation
and examples I have found are a little thin on the ground.

Thanks
Mike

Cheers for responses. I have tried this and it sort of works, I now get a
dialog box with:

The service started and then stopped. Some services do this when they do not
have any work to do.

This isnt exactly ideal however. Any more thoughts?

Cheers
Dave
