Windows service application

That code looks OK to me.

The most likely reason why it's not starting automatically is because you're attempting to use or do something which isn't available to the system at bootup time such as calling another service which hasn't yet started.

I'd have a look at the event log to see whether there are any clues there.

Hello,

Thank you very much for answering my question patiently,I have cleared all my problems and developed the service,and I am able to run the application,it is working evrything is fine.But now I face a different problem.
I have developed my service as automatic startup mode.i.e when the system reboots it should start automatically.But when I restart the system,I can only see the service there in the list,but it is not starting automatically,again I am starting that manually.....what may be the reason.please tell me.

Here I am sending the code for my installer class.

private void InitializeComponent()
        {
            this.WinMQSOAPPollservice_Installer = new System.ServiceProcess.ServiceProcessInstaller();
            this.WinMQSOAPPollInstaller = new System.ServiceProcess.ServiceInstaller();
            //
            // WinMQSOAPPollservice_Installer
            //
            this.WinMQSOAPPollservice_Installer.Account = System.ServiceProcess.ServiceAccount.LocalSystem;
            this.WinMQSOAPPollservice_Installer.Password = null;
            this.WinMQSOAPPollservice_Installer.Username = null;
            //
            // WinMQSOAPPollInstaller
            //
            this.WinMQSOAPPollInstaller.ServiceName = "WinMQSOAPPollService";
            this.WinMQSOAPPollInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic;
            //
            // ProjectInstaller
            //
            this.Installers.AddRange(new System.Configuration.Install.Installer[] {
            this.WinMQSOAPPollservice_Installer,
            this.WinMQSOAPPollInstaller});

        }

I think we'll need to see some code, Ranjith, to answer that one.

I take it you've got some code in the OnStart() method?

I'd also double-check your Main() method  to ensure you've covered all the steps in Mahesh's article.

Thank you very much.I now got an idea about the windows service.But I saw that we need to add an installer class,for the windows service.
Now I moved further but struck up again..I am able to see the service but when I start the service it is closing immediately saying that service has nothing to perform .what is the reason?

Here are step by step instructions:

Yes, you do need to install a Windows service for it to show up in the 'services' list.

There's a command line utility called InstallUtil.exe which can be used for this purpose.

So go to the VS or .NET SDK command prompt, navigate to the folder where the service resides, and type:

     installutil myservicename.exe

to install and, if you should ever need to uninstall, type:

     installutil /u myservicename.exe
