Windows Service Detecting User Log Off Event?
Aug 15, 2011
Recently while I was playing with VS 2008(VB), I have created an application for folder sync purpose... which is working fine. Then, I have created a windows service that does the same thing and it is also working fine(from application perspective). But, I have been trying to add some additional functionality to that new service. It keeps on running as long as System is ON.
But I would like to change the functionality to... as soon as user logs off Service should STOP, and should START when user logs into that PC. I tried to find some useful info online(related to my task) and all I could come up with was to add OnSessionChange(...) method to the service. But for some reason it is not working out for me(when I've logged off or other system events such as 'system lock').

After running the following code (which locks the computer), what code must I be applying to see if the user has successfully logged into the computer and that "Lock Screen" I'd so called has disappeared?
Private Declare Function LockWorkStation Lib "user32.dll" () As Long
Private Function LockComputer()
LockWorkStation()
End Function
I will call "LockComputer", after that what do I do to see if the Lock screen so called by this function (after say 2 minutes) has disappeared or is still there asking for the password from the user.

I have created a simple framework for a Windows service in VB.NET Express 2008. It enables a timer which then writes to the event log every 6 seconds until the service is stopped. This works fine. I adapted that framework into something further. It is using Windows sockets. Well, I haven't finished that part yet and I just want it to write to the event log successfully but I can't even get it to do that now. I am trying to write an event in the OnStart event. The service is being started successfully, according to the standard event log, but my custom events are not getting there. I don't understand why as I am using the same code for that as I was before.

I'm new to write windows services and I was searching around collecting necessery info and howtos. What I'm missing is the interaction between my webapp and the service. The servicecontroller sending messages to the service and gives me the main status of the service. Is there a way to get custom messages, set custom properties and get properties? If there are not, should I use a file for both the service and the web app where both can read and write on, like a settings file in xml or are there better methods? Is there a way to get the messages in the corresponding eventlog, how do I access them?

I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.
Service running under system account (in this example a simple console application)
Code:Imports ClassLibrary1Module Serv
Sub Main() Dim SDSIPC As Semaphore = CType(Activator.GetObject (GetType(ClientFromServer), "ipc://Client/SreeniRemoteObj"), Semaphore)
SDSIPC.DoSomething()

I currently have a windows service that is packaged up as an msi installer. However, during the installation i need the user to input their required filepath (to string) location. The filepath variable currently resides in my component class called MyNewService that is inherited from System.ServiceProcess.ServiceBase.
Is there anyway i can allow the user to define the filepath variable during installation?

I have created a windows service that has the Account set to user. Which means that when I install the service I need to pass a user name and password. Is there a way to set these maybe in the ProjectInstaller class maybe in the BeforeInstall event? if so HOW?

My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.

I've been developing in .NET (VB, C++, C#) for a number of years, but I am finally creating my first service application (in VB). I need to read/write to a file contained within a user's documents. As a service is not associated with a particular user, would a service have access to a user's documents? ...regardless if that user is signed on or not?

I need to get the user input for where they want the files that will be produced by my windows service to be stored.
I was thinking that i could do this by reading in the user's input to a variable in the on start event of my service? this variable is then later used in my xml writer.

I developed a windows service project using vb.net and windows service is installed with logon account as admin's user name and password. Target of windows service is to read the pst file path location from windows registry for currently logged user by accessing the following registry key
"HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfilesOutlook52a407cf2e436a4d8fe252d1d257465501f6700".
The problem is , windows service can able to read the admin pst file path location if admin is logged in windows. When other user logged in windows, service is not able to read currently logged user's pst file path location from registry because of windows service is configured with admin user name and password. so it always reads admin's pst file location.

I have a Windows Service that needs to start other processes under a user context other than that used by the service. I've seen other posts related to this but have seen no resolutionI've tried many things and have been unsuccessful in starting the process from a Windows Service when a username, password is supplied. orking as it's a requirement of our system to do this and it worked fine until recently and only fails on Vista and Windows 7 (works on XP).
The following code is used to start the process.

P.StartInfo.Domain = Domain

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I have a windows service I created that checks for data to post to an off site webservice over SSL. The service checks every 10 seconds for data to send, if there is data it opens a connection to the remote webservice, and closes the connection after 120 seconds (still checking for data to send during this time). The service works fine if a user is RDP'd into the server, but as soon as no one is logged on and the service attempts to push data, I receive the following error:"The underlying connection was closed: An unexpected error occurred on a send."I have tried running the service as a local service, network service, under my login, and under a service account, but nothing seems to work. The PC it is running on is a windows 2003 server (virtualized - vmware)

The following zipped up Visual Studio Solution on Skydrive is immediately buildable and runnable; a usercontrol on a Form. Problem? If you click on any of the Edit Buttons and move the Horizontal Scroll, the values as they change in the Label_Values are off by one when you release the slider button. I think this is a timing problem between the Paint handler and the Horizontal Scroll event handler at the very bottom of the User Control code. Sorry I didn't eliminate

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
