Eric,
Are you doing too much work in the OnStart method?
Have you tried debugging your service:
http://msdn.microsoft.com/library/de...owsservice.asp
Normally what I do is include a healthy amount of event log messages (via
..EventLog) especially in any asynchronous events that may be raised within
the service. Plus I will include Debug.Write & Trace.Write in strategic
locations.
Something like:
Public Class MyService
Inherits System.ServiceProcess.ServiceBase
Private WithEvents Timer1 As System.Timers.Timer
Public Sub New()
MyBase.New()
' This call is required by the Component Designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call
AddHandler AppDomain.CurrentDomain.UnhandledException, _
AddressOf AppDomain_UnhandledException
End Sub
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
Timer1.Start()
End Sub
Protected Overrides Sub OnStop()
' Add code here to perform any tear-down necessary to stop your
service.
Timer1.Stop()
End Sub
Private Sub Timer1_Elapsed(ByVal sender As System.Object, ByVal e As
System.Timers.ElapsedEventArgs) Handles Timer1.Elapsed
Try
EventLog.WriteEntry("Timer elapsed handler started",
EventLogEntryType.Information)
' Do work here
EventLog.WriteEntry("Timer elapsed handler finished",
EventLogEntryType.Information)
Catch ex As Exception
EventLog.WriteEntry(ex.ToString(), EventLogEntryType.Error)
End Try
End Sub
Private Sub AppDomain_UnhandledException(ByVal sender As Object, _
ByVal e As UnhandledExceptionEventArgs)
EventLog.WriteEntry(e.ExceptionObject.ToString(),
EventLogEntryType.Error)
End Sub
End Class
Note EventLog is inherited from ServiceBase and will be the normal event log
for your service, you can override ServiceBase.EventLog if you want to use a
different Event log.
I configure Debug & Trace to go to a log file.
In your app.config of your Windows Service project:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="myListener" type="System.Diagnostics.TextWriterTraceListener"
initializeData="MyService.log" />
</listeners>
</trace>
</system.diagnostics>
</configuration>
Note the UnhandledException event is not working as I expected in the above,
so I put the Elapsed event in its own Try/Catch.
Hope this helps

Hi,
I built a service that watch file in a directory. I use a simple
filewatcher and add a handler to do something when a file is created. I have
the following problem. I can build it, I can install it, I can start it but
when I start it I have a message that the service is stop because it does
nothing and it doesn't execute the code in the service. Please if you have
any idea it will be appreciate.
Thanks you
