Synchronizing a timer to prevent overlap

Question

I\'m writing a Windows service that runs a variable length activity at intervals (a database scan and update). I need this task to run frequently, but the code to handle isn

Answer 1

I've used a mutex when I've wanted single execution:

    private void OnMsgTimer(object sender, ElapsedEventArgs args)
    {
        // mutex creates a single instance in this application
        bool wasMutexCreatedNew = false;
        using(Mutex onlyOne = new Mutex(true, GetMutexName(), out wasMutexCreatedNew))
        {
            if (wasMutexCreatedNew)
            {
                try
                {
                      //
                }
                finally
                {
                    onlyOne.ReleaseMutex();
                }
            }
        }

    }

Sorry I'm so late...You will need to provide the mutex name as part of the GetMutexName() method call.
