highlight item in array control state machine

[timothy123]

Hi,

I have a state machine which I control using an array of enumerated controls. Is there a way for me to highlight the item in the array that the state machine is executing while the program is running.

Thanks,

-Tim

Not directly, but there are other solutions, for example:

1. Index out the current element and display in a scalar indicator.
2. Line up a boolean array next to it and light the LED next to the currrent state.
3. etc.

I'm guessing you can probably do this with a property node.

If you need to debug it:

-> get a probe on the indexed state

-> get a control on the indexed state

You can't hightlight an element of an array, but you could color it on a table, select it on a listbox ....

But please also take the following advice: If you use a so called 'queued state machine', don't do that. They are not state machines (also promoted by NI) and a very bad design pattern. They are ok if they are pure queued message handlers (so no insert into queue inside the state execution) or if you seperate procxess queue from the states (have an idle state that popsout new states when all processing is done).
