Cluster Aware Windows Service?
Mar 5, 2012
I have a Sql Server 2008 R2 Failover cluster running an active and passive node talking to a shared disk.
I have developed a vb.net windows service which needs to run on each node under clustering conditions.
I need to understand what I need to do to the service to make it cluster aware.
There are a few heavy classes in the service which under failover conditions need to understand where they are in terms of what data is in them so that when the passive node kicks in and the service starts it picks up on node 2 where it left off on node 1.There is near little documentation on this subject I can find on the net and with companies becoming failover happy this needs to change.

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 need the cluster member to auto run a batch job when the cluster resources are fail over to it from another member. I use the vbscript below:
Dim WshShell
Set WshShell = CreateObject("WScript.Shell")
Function Online()
[Code]...
The problem is I can't bring it online in cluster administrator, and can't trigger the batch job. It show an error code and I think i miss something in the code.

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?

When 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?

We 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?

I'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

WPF question here, I'm using VB.NET as the code-behind so I figure I might get away with posting it here :P Just in case anyone has any ideas.I've got a StoryBoard that runs on MouseEnter and MouseLeave, basically all it does is scales the control up a bit to make it larger and moves it accross the screen slightly (on MouseEnter) and then on MouseLeave it just sets it back to how it was.
The problem is that the animation lasts for about 1.5 seconds, but if the user just passes their mouse over the control and then half way through the animation they move the mouse off the control then the second StoryBoard kicks in but starts with the control in its final position from the MouseEnter animation. Obviously this results in a "skipping" or "jumping" effect in the animation and is less than ideal.So I'm just wondering how you are supposed to make it so that if an animation is half way through and then another event is triggered so another animation starts then it kind of 'gracefully' hands over to the animation that is starting.

I have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.

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.
Here is my code:
Public Class Form1
Dim SystemMary As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
SystemMary = Mid(TimeString, 1, 2)
[code].....

I am working on a .NET Windows Service where I am trying to store settings that will be used when the service is started and while it is running. I have searched through posts on SO and found that using the Settings in the properties of the project is great for use with console and winforms applications. However, Google and SO are silent when it pertains to storing these settings with a windows service.
