Windows services

[Zak Koufakis]

Has anyone created a Windows service using the EiffelStudio? Delphi, for
example, provides an API to the Windows SCM (Service Control Manager)
that can be used to make created applications register as windows
services.

 

How do we do this in EiffelStudio?

 

Thanks,

 

Zak

Doesn't work. I spend days trying to get this to work. Somehow it
clashes with Eiffel's Threading mechanism.

Things like this go a long way to explain why Eiffel didn't have more
traction in the real world. It couldn't/can't do many real world things.

With Eiffel.Net I believe you can implement this though.

Have you tried recently? I remember that for 5.7 we fixed issues when
threads are created outside the main Eiffel program. Also isn't it a
possibility to spawn an Eiffel process from a wrapper used as the actual
service?

I would turn this the way around, it is because the majority of Eiffel
developers are happy with what they have or they don't spend enough time on
developing libraries or interfaces with the outside world. Eiffel is open
but one has to do some work to integrate with third party tools and
libraries. Eiffel Software can do part of the work but Eiffel users should
really do the rest. And with our code being open source there is really no
restriction to the later and we should encourage them to share their work
when they do something that could be reused.

Regards,
Manu

Berend thanks for your reply.

You sound like an "angry Eiffelist" - someone that feels "betrayed" by
the woman he is in love with. I understand your frustration but its part
and parcel of the trade-off people that like Eiffel have to make. The
woman we are in love with has other virtues (I hope I won't get into
trouble by assigning Eiffel a gender).
 
>Doesn't work. I spend days trying to get this to work. Somehow it

I had a look at your website (Paul G. Crismer pointed me to it) and I am
aware of your work to write a library for this but I haven't tried it
yet. I need first to understand the underlying Windows SCM mechanism.

Can you please explain why it wouldn't work? Have you tried with a post
4.7 Eiffel version as Manu suggested?

Regards,

Zak

I think I tried that as you suggested that at the time, but it worked
even less I believe.

The VisualBasic route.

Well I agree and participate of course. But my remark was more directed
at the bewilderment some people express why Eiffel isn't used more. And
that is that integrating outside Eiffel was/is hard, especially on the
Windows platform.

So it's perhaps not the developers who don't use Eiffel as that Eiffel
wasn't very usable outside certain niches. With Eiffel.NET that
situation has changed somewhat of course.

But I must say that Eiffel now works very well on Unix :-)
