Override Teststand callbacks from LabVIEW.

[HichemB]

Hello,

I have a test sequence and I want to override the "SequenceFilePostStepRuntimeError" callback from a LabVIEW code module.

I tried to register for callback event in LabVIEW but I was unable to find a callback with this name. I just found the UIMessageEvent.

I would be very grateful if anyone could help me with hints on how to override Engine callbacks from LabVIEW.

What you are trying to do can't be done, nor does it make sense.  Maybe you can elaborate a little more on what your goal is and there is a better way to accomplish it?

In your images you are looking at 2 very different kinds of callbacks.  The first image shows an Engine Callback which is native to TestStand.  The second image shows an event callback which is native to LabVIEW (yes I get that they are coming from the TestStand engine, however, that is because those are the events for the engine class.  Totally different animal than the purple sequences defined as Engine Callbacks).

This describes Engine Callbacks: https://zone.ni.com/reference/en-XX/help/370052R-01/tsfundamentals/infotopics/engine_callbacks/

And this describes the events for the engine class: https://zone.ni.com/reference/en-XX/help/370052R-01/tsapiref/reftopics/engine/  Apparently there is only 1.

Thank you ~jiggawax~ for your reply, this helped me understand more the callback concept.

I solved my problem by inserting the callback programmatically from LabVIEW as the following.
