Windows Service
-
Hi, I am writing an application for Windows Service, I want to run this Service for every 1 minutes, the Windows Service does call some database objects and performs operations, this is fine up to here. But my question is what if the first cycle of Windows Service didn't complete its operations and if second cycle starts, doesn't this interference can cause Service to fail. Similar type of question I have for the Windows Scheduler too, what if the first cycle of Windows Schedule hasn't completed yet and as per timing if 2nd Scheduler cycle tries to run the same application, isn't it going to interfere and created Problems. Any help a code snippet, a link or a suggestion is going to help me a lot, thanks in advance.

The Windows task scheduler has an option to not start a new instance if the task is already running.

That could be answered in a few minutes by testing it. Create a task that writes somewhere for one minute. Start them from your service or the Task-scheduler, with an interval of 10 seconds. So, unless you do something that locks (writing to files and the like) it should not fail.

Why not just code the service to do its own timing internally? That way you can prevent a new cycle from starting if a previous one has not completed.

Hi Richard, Can you please give me the name of the option if you don't mind?

It's at the bottom of the "settings" page: Screen-shot[^]

If you can add the request to in-memory .net queue it should solve your problem. Keep a thread which will monitor and trigger job from the queue. This way you can decide on a number of threads which can run parallelly (one or multiple).
