I thought that I read somewhere that services don't (or can't) have forms.
Is that true?

A service doesn't use forms, because the service is meant to run unattended
once it's started/executed, with no user interfacing.
But a Windows desktop application using a form can communicate with with a
service application, just like you see a personal firewall UI that
communicates with its FW service application.

Do you know of any examples of this that I can learn from?

Nope, not true at all. A Windows Service can have all the forms it want.
There's even a handly little "Allow Service to Interact with Desktop" check
box you can explore in the service admin screen.
Now, as to the wisdom of having a Windows Service do Forms, that's another
story. If you go this route, you need to have a good answer for "What to do
if nobody is logged in?", and all of the edge cases around that.
Most people solve this by having the Service not have any Forms code, and
instead use a Remoting Proxy and an Admin Application. This seems to work
better. Just go look up "Remoting" and you'll find a number of examples all
over CodeProject.
If you want forms in your service simply for the sake of debugging, you can
take the hybrid approach: http://www.coversant.com/dotnetnuke/...=88&EntryID=19
The approach I talk about there works for Console and WinForms apps.

This is a C# example and everything that's being done in C# as far as using
the namespace can be done in VB.NET as well. http://www.codeproject.com/csharp/se...controller.asp
You can also issue custom commands to the service. http://dotnetjunkies.com/Tutorial/C4...643EEF8A6.dcik
It's a one way communications, but you could create trigger files or other
means in the service to let the Windows application know that an event has
happened, as an example.
Oh, one other thing I like to do when debugging a service application,
particularly, when debugging a library that I have written that the service
is using and I need to send messages to help in the debugging is do NET Send
commands back to the workstation the service is running on. The Windows
Messenger service must be enabled on the machine so that messages can be
seen, with a popup message window being displayed.

Are you aware that you are in a VB.Net newsgroup?

Yes, I am aware I am in a VB NG. However, most examples of things are in C#
..Net. You can search Google and see if you can find some examples in VB.
Once again, there is no difference between C# and VB.Net. The only
difference between the two languages are syntactical. You should be able to
take the C# example and come out with a VB example doing the same thing.
I comunicate with a few of my services with remoting
this might be an option for you to

A quick scan of the group did not immediately reveal an answer to my
questions so here goes.
First let me describe my app and then I'll ask the questions.
I am writing a Windows Forms App (not Web Forms) that serves as a thin
client to some web services. In other words, the Windows Forms app will be
installed on the client machines and that app will call web services that
are deployed on my server.

Hi folks,
So I have implemented a Web service which provides several Web Methods.
Before the client can use the WebMethods they must first be authenticated and
authorized i.e. they login, obtain a string 'ticket' and then must use this
ticket to make subsequent calls to the Web Methods.
Users are validated by checking to see if they exist in the web.config file

Hi everyone,
We have a need to make a Windows Forms (2.0) client application that

The data that the application uses needs to be centrally available to a
potentially large number of other sites, which would seem to leave us
with our traditional approach, or having a central database server on a
dedicated server someplace.
