Source property was not set before writing to the event log.

[Skittle]

I have put together a simple service program.
It has a file watcher to recognise when files are moved into a folder and it will move them somewhere else.

I have included event log write events so I can log what it does.

I write an eventlog event within the 'On Start' event on the service but the program seems to fail on it. When I start the service program it crashes and puts the following error to the event log:-

Service cannot be started. System.ArgumentException: Source property was not set before writing to the event log.
   at System.Diagnostics.EventLog.WriteEntry(String message, EventLogEntryType type, Int32 eventID, Int16 category, Byte[] rawData)
   at System.Diagnostics.EventLog.WriteEntry(String message, EventLogEntryType type)
   at ServiceFileMonitor.ServiceFileMonitor.OnStart(String[] args)

I have set the properties of the 'Source' for my log both within the properties window of visual studio and hard coded in the On Start event yet still I get this error. As far as I can see I have coded the log exactly the same as on a windows form program that works fine. Can anybody advise me where I am going wrong?

Protected Overrides Sub OnStart(ByVal args() As String)
        ' -------------
        ' START SERVICE
        ' -------------

        Try

            ReadParameters()

            FileSystemWatcher1.Path = strDeliveryFolder
            FileSystemWatcher1.EnableRaisingEvents = True
            strMessage = "ServiceFileMonitor Started."
            EventLog1.Source = "ServiceFileMonitor"
            EventLog1.WriteEntry(strMessage, System.Diagnostics.EventLogEntryType.Information)

        Catch ex As Exception

            strMessage = "Error. " + ex.Message
            EventLog1.WriteEntry(strMessage, System.Diagnostics.EventLogEntryType.Error)
            SendErrorEmail(strMessage)

        End Try

Dazed and confused.

Resolved it.

It was a bit oblique.
I was coding the project on a remote drive and for some reason when I copied it to my C drive and recompiled it works fine. I think somewhere along the line I was simply installing the wrong version.
