Error in windows service

[mrk98]

Hi,

I am getting the following error when I try to start the windows service I have written:

ReadOutlookService on local computer started and then stopped.Some services stop automatically if they have no work to do, for example the Performance logs and alerts service.

My Service.cs contains the following:

 protected override void OnStart(string[] args)
        {
            // TODO: Add code here to start your service.
            eventLog1.WriteEntry("ReadOutLookService OnStart");
 
            tm.Enabled = true;
            //tm.Start;
            tm.Elapsed += new ElapsedEventHandler(Timer_Elapsed);
        }
 
       protected void Timer_Elapsed(object sender,
         System.Timers.ElapsedEventArgs e)
        {
            try
            {
                //eventLog1.WriteEntry("Timer started");
                _Application olApp = new ApplicationClass();
                _NameSpace olNs = olApp.GetNamespace("MAPI");
                MAPIFolder oInbox = olNs.GetDefaultFolder(OlDefaultFolders.olFolderInbox);
                Items oItems = oInbox.Items;
                for (int i = 1; i <= oItems.Count; i++)
                {
                    _MailItem oMail = (_MailItem)oItems.Find("DTE Time Reminder");
                    oMail.Display(false);
                }
 
            }
            catch (System.Exception ex)
            {
                throw (ex);
            }
        }
 

How do I debug the service ? The service gets installed, but I am not able to run it, since it starts and stops immediately.

Thanks in advance,
mrk

Hi,
1. Try and log the error in a text file.

try{
 
}
catch(Exception)
{
// code to log text file
}
 

2. Check the service account. It should have permission to write to event logs and file system.

Hi,
Can you elaborate how I can give permission to the ServiceAccount to write to eventlog or file system ? I have used LocalSystem account.
Thanks,
mrk

Can anybody give some pointers ? I just want to create and run a simple windows service..

Hi,
Run the service under "LocalSystem"(for testing, later on maybe you can change it to some other account). This is the highest account( most privileged). Try and run the code in a console application, see if you find any bugs. If it runs fine, then maybe its a rights issue.
Creating Winsows service (look into ServiceAccount).

Generally when your service produces that "error" about starting and stopping, it means it had no work to do. Which would lead me to believe there is trouble in your OnStart call, in that the service control doesn't believe you are trying to do anything. Your timer_elapsed function might not be recognized as a true thread that does work?
