Windows Service Logging - Visual Basic .NET

Ron Bremmers

Hello,

I have a Windows Service which executes some code each 2 seconds.

Every 2 seconds I want to log the result in a Windows Forms application.
What is the best approach? I think it is .NET remoting, but when the
"client" application is not started, no logging has to be done. So the
service has to know if there is a client application to log to. How can I do
that? Any suggestions?

Thanks!

Ron

Ron,
You can use .NET Remoting: the Windows Service would have a single remoting
object that raises an Event.

The Windows Forms app would handle this event (remotely) when it is running.

The Service would simply raise the event, it doesn't care if there is any
one is handling the event or not.

In fact multiple Forms apps could handle the event, and they would all be
notified!

Matthew MacDonald's book "Microsoft Visual Basic .NET Programmer's
Cookbook" from MS Press has a topic on "Fire an Event over a Remoting
Channel" that shows how, plus information on how to enable 1.1 to work.

Alternatively you use Message Queuing (MSMQ) via the System.Messagin g
namespace to send out messages, in this case I would have the message expire
in 2 minutes, not persist it, nor send it to the dead-letter queue, as the
message is simply notifying the client...

Hope this helps
Jay

Windows Service and logging off

by: Todd Bright | last post by:

Does anyone know of a reason that a Windows service written in C# would prevent the system from rebooting or logging off? The service starts another thread which displays a form (processing is done in the form so as to not interfere with the service's thread execution). Stopping the service is the only way I've found to yield and let the system reboot or log off. I tried using the SystemEvents.SessionEnding event and that works great for...

Windows Service grinding to a hault

by: JJ | last post by:

I have written a multi-threaded Windows service. I developed it in such a way that the core logic is a separate class library from the actual service project, so I could test the .DLL in a console. In the console test app, the app will run for days on end without a problem. All necessary calls are thread safe (lock). However, when plugged into the Windows service, the darn thing simply grinds to a halt i a matter of minutes. No exceptions,...

Error tracking a windows service

by: OpticTygre | last post by:

What is the best way that anyone has found to capture errors inside a windows service? It's pointless to use compilation constants, as you can't "debug" a service very easily, and you can't pass in a command line arguement (can you?) to tell it to do something special like capture errors to a file while it's running. Has anyone figured out any good ways to do this type of run-time error capturing? Basically, if I were building a...

AppDomain.UnhandledException in Windows Forms and Windows Service

by: Chris Dunaway | last post by:

I am attempting to use the AppDomain.UnhandledException event in a Windows Forms app and also in a Windows Service. But the event doesn't seem to be called. In a Windows Forms app, the event IS called but only if I run the app through the IDE. If run standalone (release or debug build, it doesn't matter), the event handler is never called. In the Windows Forms app, I changed it to use the Application.ThreadException event and that...

how to make a python windows service know it's own identity

Hi all, I have used the win32com libraries to set up a service called MyService under Windows. So far, so good. Now I need to run multiple copies of the service on the same machine. I also have that working. For monitoring and logging, I'd like each instance of the service to know it's own identity (MyService1, MyService2, etc.) But I can't quite seem to grasp how to do this.
