Class MySample
   Public Shared Sub Main()
      Try 
         Dim myNewLog As New EventLog()
         myNewLog.Log = "MyNewLog"
         myNewLog.Source = "MySource" 
         ' Create the source if it does not exist already. 
         If Not EventLog.SourceExists("MySource") Then
            EventLog.CreateEventSource("MySource", "MyNewLog")
            Console.WriteLine("CreatingEventSource")
         End If 
         ' Write an entry to the EventLog.
         myNewLog.WriteEntry("The Latest entry in the Event Log")
         Dim myEntryEventArgs As EntryWrittenEventArgs = _
                                    New EntryWrittenEventArgs()
         MyOnEntry(myNewLog, myEntryEventArgs)
      Catch e As Exception
         Console.WriteLine("Exception Raised" + e.Message)
      End Try 
   End Sub 'Main
