Hi there,
we are creating some automated backup solution for some user application (let's say "UserApp" ;)). Now, the backup service is working perfectly.
But there's a problem: the backups cannot be created if some user is working with the "UserApp" at the same time, because of locked files, etc. So the service should be able to tell the user to close the application and wait until the user does.
As I already know that a service shouldn't (and since Vista: CANNOT) communicate with the user "directly", I thought of a system tray icon where the user also could see whether the service is running.
Now I also partly created such a tray app and it is working well so far.
My big problem is now, that I don't have a clue about creating a client-service-communication. As said, I want the service to send some sort of message to the system tray application, which then perhaps translates that message and informs the user with a ballon tip for example.
Is there a simple way to achieve this?
How would you going to do this?
Which sort of communication would you use? IPC? Pipes? Sockets?
I have read many articles and threads about this topic, but I couldn't find any proper solution and/or how to implement that.
Thanks in advance for helping me ;)

Is there really no one, who can help me?
I really need a solution very soon and I'm stuck with this one :(

You could use Named Pipes... You can also look into WCF...
A simple approach would be write to a file (in a specified folder) and have your windows form app watch it... Read from file and display the status ... Just make sure your win form app has rights to read the file ...
@DeepBlue
Thx for the reply ;)
I also thought of named pipes. But how do I implement named pipes in C# (or .NET)?
I've read those msdn articles, but they are written for C++ and it seems to me that those methods are not available for C#.
Perhaps I'm searching with the wrong words, but I didn't find any (good) articles/tutorials about implementing named pipes in C# (or .NET).
So can you (or somebody else) please tell me how to do this?
Thank you & have a nice day ;)

Well I somehow managed to get it to work with IPC in the meantime. :)
Working myself through that complicated C#-Named-Pipes-With-Native-Methods-Wrapper-Stuff would have been too much overhead, compared to my (simple) solution.
Thanx anyway ;)

Hello all, I wrote a shell program a few years ago in VB6 that needs

it, it minimizes to the system tray. With no task bar, there is no
system tray, so there is no way to restore the PC Anywhere window.
The shell starts PC Anywhere using ShellExecute. I...

Hi all,
While creating a windows service using .NET and C# I had to call
myForm.ShowDialog() from within a thread I have created inside the OnStart()
method.
When this window is closed, my thread terminated and the tray icon displayed
is removed. The service runs ok while the user is logged on the system.
When the user logs off, all windows are closed (including the one from my
service - I used 'Service Interacts with Desktop') but...

Hello all,
I have created a windows service and now I would like to have a
configuration page in the system tray. Basically an icon I can click on
which will just interact with an XML file. What is the best way to do this?
1. How do I use the System Tray and add an icon on it. Yes, probably
basic.. and I can do it with VB but have never tried with C#.

Hi,
I'm having a hard time getting my service to show a sys tray icon. I've
tried to create a separate Windows application where I simply add a
notification icon to the form. In the OnStart method of the service I simply
try to start the windows application which then should show the icon.
I can't get it to work! When I run the separate Windows application the icon
turns up, but when I start it from the service it doesn't. How should I...

Hi,
I want to develop a Window Service in C# that should be capable of
sisplaying the a icon in the window tray.
Based on some logic in service, icon should be changed to some other
color/image and I needed single click, double click event and context
menu also on that tray icon to perform some other operation and show
some window form.

The conventional approach is easy enough; drop a NotifyIcon onto a Form.
When the form is loaded - bingo - the icon appears in the System Tray.
I can't use this approach though. I'm writing a service. But I'd like my
service to install an icon on the System Tray so that the user can start /
stop / and otherwise control the service interactively, and without having
to go to the Services applet. How do I do this?
Thanks for your advice.
