Hi
How does one return a varible, value, or object from a window service
in .net?
How do I expose the service methods?
A link, code, or anything is wellcome, because I'm going bonkers!

You are going to have to be more specific.
A Windows Service is a process (.exe) that is run by the Service Control
Manager. You can not "return" a variable or object from a process
(whether it is a service, or a console application, or a winforms
application).
Where and what do you want to return the data to?

Well, I have a windows service, that I want to do a Interface to. It
has runtimevalues (shedules in a sealed class), that I need to access.
So I want to return, preferably, an object (arrylist) to the interface.
If that's impossible, then perhaps a string value ...
I can understand the need to isolate the service process as such, but I
have diffuculties understanding the trouble of making disconnected GUI
to check runtime data...

Remoting is one way to do this (I have used remoting for the exact same setup
as yours). Remoting is a way of doing inter-process calls in .net. Try
doing a search for remoting on MSDN to get started.

Hi
I've done the return-string-chat mentioned in every example, but I'd
like to
know how i can expose an object from the service or, even better - a
method.
In essence I'd like to be able to return an arraylist from the service
and/or do a method call. If all else fails return a string from inside
the service to a client...
maybe I'm missing something here but I don't really understand
remotingobject (as compared to how you could use windows services
before).
How do i instatiate an object inside the service (as singleton) and use
it in both service and inteface?

Hey Erik,
Remoting really does not have anything to do with Windows services but if
you want to call objects in your service process from another (UI) process
then remoting is the way to do it. Remoting is a bit like DCOM (in the "old"
days) only simpler. The remoting architecture supports singletons so it is
ideal for calling objects living within a service. It even lets you use
events so that the service can notify the UI of any changes (this is a bit
tricky though but it can be done).
Of course, there are other more simple ways of communicating between a
service and a corresponding user interface. E.g. you can let the service
create files in a well-known folder and then have the UI process read these
files (and the other way around) but you might run into synchronization
problems.
If you want I can try making a small sample project for you - in that case
just send me an e-mail.
Regards, Jakob.

If I manage to call the following bit of javascript in IE and MZ
w = window.open("", "s", 'status=no,resizable=no,width=450,height=450');
I get a window that is not resizable and without a statusbar. Yet FF
gives me both a statusbar and the window is resizable! Does this mean
that FF does not support these "features" or is there a different way to
code them for FF?

I wonder if it's common to raise events from the service(the remote object

I am thinking about something similar to COM+ snap in "Transactions

The services, talked here, are things used in IServiceContainer,
IServiceProvider, etc.
In my opinion, everything can be a service, and a service is generally
used for providing specific features for service consumers, at design
time. But, I think the cnsumers must completely know all aspects of
that service. This sounds not good, and breaks the decoupling rule.
So how to understand the role of Service, in a software engineering...

Hi,
I'm working on a window service and i want to give an interface to it. What can be the best approach to get this done.
Can i include a Form, when the user starts the service then gives some parameters only on the start. then the service is started and continue its work.
No need to give values on run-time.
Looking for best approaches.....................
