Seeking best pratice to modify input of DQMH Event

[Behr-33]

Hello,

I want to update inputs of a module Event (Request and wait for reply).

I am seeking for DO and DON'T on this specific operation. 

I would like to avoid deleting existing event and creating a new one... But may be you will tell me this is the only way.

Regards

Deleting and creating again is one option.

The other one is going to the module's Public API folder, there, you will see the Arguments folder. Find the typedef for the arguments that you want to change and modify it. Now, you need to make sure you modify the Request, and where the Event handles the request. Same for the reply. A way to do this is to right-click on the typedef on the project and select to find callers, go to each one of the callers and make sure the new elements are handled correctly.

I hope this helps.

Happy wiring,

Hello

It works ... and the operation enabled me to understand better DQMH framework: two birds with one stone

Thank you

Would be nice to have this as an action in the DQMH menu together with the create, rename etc. options.

What would you like that menu item to do? Let you select the module, then the event, and it will open the corresponding typedef and event VI for you so you can edit them?

Hi Joerg,

I wasn't the original requester, but I would imagine selecting the event, and then the "event arguments window" (and event payload if applicable) would open up with whatever data is already being used by that event. Then the data elements could be modified, and a scripting tool would go to the necessary places in the DQMH module to make sure the data can get to its final destination in the message handling loop.

"What would you like that menu item to do? Let you select the module, then the event, and it will open the corresponding typedef and event VI for you so you can edit them?"

It would follow the model of the other event options, so yes it would ask you to select the module and event first, then let you edit it through a UI similar to the one you used when you configured the event in the first place.

If it was made specifically to only edit the argument it would just show the argument editing window as it appeared during event creation and you would then adjust it and everything would update accordingly.

I agree that this would be a useful scripting tool. It's the #1 thing I've seen new DQMH developers trip up on once they get used to all the other scripting tools.

This idea has been proposed before on the DQMH Feature Requests page here. Although the idea is currently "Declined", I'm hoping the DQMH Consortium reconsiders and includes this feature in a future release.
