Question

How do I write a Alert which will run at 00:00, 00:15, 00:30, and so on every day?

Can you give me an example code?

Thank you.

Answer 1

You can use a timer that runs every minute that checks the current time. The check can look like:

private void OnTimerTick()
{
    if(DateTime.Now.Minutes%15==0)
    {
        //Do something
    }
}

But if you are looking for a program or service that has to be run every 15 minutes you can just write your application and have it started using a windows planned task.
