timer event. but it did not
the started and stopped succesfully logs do show in the applaction log.I
created a windows form app that do the same...and it worked!?
i tried all posible account property...here is the code from my timer event

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Timer1.Tick

' Create an EventLog instance and assign its source.

Dim myLog As New EventLog

myLog.Source = "Service1"

myLog.Log = "Application"

' Write an informational entry to the event log.

myLog.WriteEntry("Writing to event log." & vbCrLf & Now.ToString)

end sub



i tried using the service eventlog like this:

Me.EventLog.WriteEntry("Service 1 stopped succesfully at:" & vbCrLf &
Now.ToString, EventLogEntryType.Warning, Now.Millisecond)

it did not work either

then i set the autolog property to false and wrot from onstart and onstop to
the log and IT WORKED!! but not from the timer event:(

is it security or WHAT?!

This is not a security issue. It seems that you are using System.Windows.Forms.Timer which may only be used in Windows Forms. You should use System.Threading.Timer instead

Majed,
In addition to the others comments, the following recent articles in MSDN
Magazine explain the difference between the three timer objects in .NET &
when to use each.

http://msdn.microsoft.com/msdnmag/issues/04/02/TimersinNET/default.aspx

http://msdn.microsoft.com/msdnmag/issues/04/03/default.aspx

The above articles also discusses if & how each timer interacts with
threading.

I'm using System.Timers.Timer (instead of System.Threading.Timer) in my
Windows Service, as I don't really need the extra features of
System.Threading.Timer. Either should work in your case.

Hope this helps
Jay
