validating input value

[asaf]

Hi All ,

I have an input parameter that i want to check its value when i press some button.

if the value is not as i expect than i want to prompt the user for invalid input values.

This all happen in event-case loop (if it has any affect on your answer ..)

how do i do it ?

Thanks

Hi

Use the producer/consumer-pattern. Using the event-structure you can feed a queue with elements, which are dequeued in a second loop, which contains a case-structure. So if you detect invalid data, you just can enqueue new appropriate elements.

Hope this helps.

Hi ,

The only thing that interest me is how to prompt the user with that warning .

can you focus on that ?

Attached you find an very simple example, how I would do it. Of course the vi itself could be coded better, but just to give you an idea.
