Question

hi i am working on c# window services, for that i have set some timer code in onstart method as below code i have pasted it:

protected override void OnStart(string[] args)
{
    timerjob.Elapsed += new ElapsedEventHandler(CsvGenFromDatabase);
    // ad 2: set interval to 1 minute (= 60,000 milliseconds)
    timerjob.Interval = Convert.ToDouble(DueTime);
    //  ////ad 3: enabling the timer
    timerjob.Enabled = true;
}

CsvGenFromDatabase is my method which will so my service, here my problem is i have set a timer (duetime) about 1 min for example if i tested simple volume job means it was performing good, if suppose if i given a huge volume of work for service to do when timer (duetime) was same 1 min at this scenario i m facing some error because still service work does not completed full but time 1 min passed away since service will poll new instance past work was not completed fully, for this scenario how do i handle to my service with out effecting any work when service was in one instance,kindly can any on give suggesions please

Answer 1

In your CsvGenFromDatabase method you could call timerjob.Stop() before your long running process. Once the process has complete you can call timerjob.Start() to start the timer again.

Example:

private void CsvGenFromDatabase()
{
    timerjob.Stop();

    //long running process

    timerjob.Start();
}

I’m assuming timerjob is available globally.
