Best practice for AddIn command to be executed at regular interval?

[DynamicObjects]

Hello

I have a webAPI running on a server with the following endpoint : http://api.myserver.com/HasJob 

I would like Inventor to poll this endpoint every 10 seconds in order to determine if there is a job for Inventor to do.

I have followed the examples in the SDK to create a C# AddIn that is loaded when Inventor starts.

Inventor.ApplicationEvents exposes many different events but I don't see a timer-based event. What would be the best-practice way for me to trigger my polling action every 10 seconds?

My idea so far it to :

• add a handler for the .ApplicationEvents.OnReady event during the StandardAddInServer.Activate() method called when Inventor is loading addIns.
• in my OnReadyEventHandler() set up a standard System.Windows.Forms Timer class to call my poll method. and set the interval to 10 seconds..

Is this considered to be best practice?

Regards

Dan

Just to add detail .. I am concerned about the timer event firing when the User/Inventor is in the middle of some action - I only want it to execute if Inventor is idle.
AFAIK Application.Ready relates only to initialisation, and this 2014 post (https://forums.autodesk.com/t5/inventor-customization/idle-event-in-autodesk-inventor/td-p/5397569) indicates Inventor api does not have an .Idle event back then.
Does anyone know if the api includes anything now to provide for this?

Hi,

You may consider using BackgroundWorker (https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.backgroundworker?view=netframework...) for your case.

For example, query your service in the worker thread and report progress to creator's thread when necessary.  ProgressChanged event will be handled when Inventor in not busy, and it is safe to use Inventor API in it. And yes, you don't even need a timer for scheduling in the worker thread.
