Timer in a Window Service not "ticking"

P: n/a
I'm trying to create a nifty Windows Service that will perform tasks at a
predetermined interval.

To make sure I understand the timing correctly I have set an emailer utility
to email me on the start and stop of the service...this works fine. However,
I am trying to test the "ticking" of the timer control and have an emailer
in the sub that handles the timer tick, unfortunately it does not appear to
be ticking...

Can anyone tell me what I'm doing wrong here? (Code below)

Thanks Chris,

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.

'load settings xml file

Dim xmlSettings As New XmlDocument()

xmlSettings.Load("c:\carrotink\nexus\nexusservice\ settings.xml")

'set connection string carrot patch node

Dim nodeConnectionStringCarrotPatch As XmlNode =
xmlSettings.DocumentElement.SelectSingleNode("./settings/connectionStrings/c
arrotPatch")

'set connection string commerce node

Dim nodeConnectionStringCommerce As XmlNode =
xmlSettings.DocumentElement.SelectSingleNode("./settings/connectionStrings/c
ommerce")

'set smtp server node

Dim nodeSMTPServer As XmlNode =
xmlSettings.DocumentElement.SelectSingleNode("./settings/notification/smtpSe
rver")

'set smtp server node

Dim nodeEmailSender As XmlNode =
xmlSettings.DocumentElement.SelectSingleNode("./settings/notification/emailS
ender")

'instantiate settings object

_settings = New NexusService.Settings(nodeSMTPServer.InnerText,
nodeEmailSender.InnerText, nodeConnectionStringCarrotPatch.InnerText,
nodeConnectionStringCommerce.InnerText)

'start the timer

timerMain.Interval = 5000

timerMain.Enabled = True

timerMain.Start()

'send an email that service has started

Dim notifier As New NexusService.Notification(Me.Settings)

notifier.Email.Notify("chris", "Service - STARTED - " + Now(), "Service -
STARTED at " + Now(), Web.Mail.MailPriority.Normal)

End Sub

Private Sub timerMain_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles timerMain.Tick

Dim notifier As New NexusService.Notification(Me.Settings)

notifier.Email.Notify("chris", "Service RUNNING - " + Now(), "Service -
RUNNING at " + Now(), Web.Mail.MailPriority.Normal)

End Sub

Protected Overrides Sub OnStop()

' Add code here to perform any tear-down necessary to stop your service.

timerMain.Stop()

Dim notifier As New NexusService.Notification(Me.Settings)

notifier.Email.Notify("chris", "STOPPED - " + Now(), "Service - STOPPED at "
+ Now(), Web.Mail.MailPriority.Normal)

End Sub

Chris,

Without looking to closely :), it is my guess that your timer is a
System.Windows.Forms.Timer. That will not work without a message pump
on the thread. You will want to use either the System.Timers.Timer or
the System.Threading.Timer.

Thanks Tom!

I didn't realize that.

Setting it up as a System.Timers.Timer works like a champ!

I hereby proclaim you a guru.

Thanks again,

Chris
