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.

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:
The approach I talk about there works for Console and WinForms apps.

Do you know of any examples of this that I can learn from?
the namespace can be done in VB.NET as well.
You can also issue custom commands to the service.
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.

Re: Can services have forms?
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.

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.

..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 hate .Net, but the job calls for it. I used to code in VB because I just
hate the syntax of C++. I like more verbose, natural languages. So, the
odds of me learning C# so that I can work in VB.Net are exactly zero.
