How to add this functionality a vb.net windows service ? Here is what I've added, but not getting triggered when I tried to log off or lock the pc.

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').

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 have the following code, when I comment out the While loop, the service starts without any problems, but when I have that it wouldn't start, how can I go about doing the loop right after the service is started?
Protected Overrides Sub OnStart(ByVal args() As String)
Dim serverSocket As New TcpListener(IPAddress.Any, 8000)
Dim clientSocket As TcpClient

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?
View 1 Repliesi 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.

View 4 RepliesIn 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?

View 3 RepliesWhen you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?
I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.
I need to be able to detect when an external program closes so that I can start another event within VB 2005. I have tried to do this by monitoring the processes on my computer. The problem is that this programs comes up as some weird sub-process. It has an Image Name, which is indented from the other Image Names, and it shows that the User Name is the Administrator. This is the only information you can get from the Processes tab. There is a Task Name under the Applications tab, however. I was wondering if there was some code to monitor the Applications tab instead of the Processes or if there is yet another way to do this.
View 1 RepliesWe have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

View 6 RepliesI've created a windows service and started a deployment project for it. I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.
I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.

Imports System.Windows.Forms

I'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.
