event monitor and thread sleep

It checks the event type and fires SQL stored proc if matched

If this is Console application, you need to find the way to wait for user input, for example:
Press any key to continue...
and after pressing key exit. All time when it is active, it monitors Event Log. I don't know how this can be implemented in the Console application. Maybe you need Windows Service or Windows application which adds icon to system tray and allows to select "Exit" from the context menu. But main question is: how do you want this application to look like? Should it have user interaction, how should it be started and stopped?

You could either create a thread to handle the events and come up with some "stop" mechanism for the main thread, or just do something like the example from help below (excuse the vb but you get the idea).  No reason it wouldn't work in a console.  As AlexFM mentions, a service might be more appropriate in which case your code is threaded anyway.

Class MySample

    ' This member is used to wait for events.
    Private Shared signal As AutoResetEvent


    Public Shared Sub Main()


        Dim myNewLog As New EventLog()
        myNewLog.Log = "MyCustomLog"

        AddHandler myNewLog.EntryWritten, AddressOf MyOnEntryWritten
        myNewLog.EnableRaisingEvents = True


        signal = New AutoResetEvent(False)
        signal.WaitOne()
    End Sub ' Main


    Public Shared Sub MyOnEntryWritten(ByVal [source] As Object, ByVal e As EntryWrittenEventArgs)
        signal.Set()
    End Sub ' MyOnEntryWritten
End Class ' MySample

        EventLog myNewLog = new EventLog();
        myNewLog.Log = "MyCustomLog";                      
       
        myNewLog.EntryWritten += new EntryWrittenEventHandler(MyOnEntryWritten);
        myNewLog.EnableRaisingEvents = true;
       
       
   signal = new AutoResetEvent(false);
   signal.WaitOne();        

    }      

    public static void MyOnEntryWritten(object source, EntryWrittenEventArgs e){
        signal.Set();
    }
}

Through experimentations ... it seems the thread gets awoken by events (I put the thread to sleep for hours, but events still fire).

Does this means that event listeners are run on their own threads?
