EveryNCallback for Retriggerable AI Using Retriggerable Counter

[knowhow]

Hello

I want to use EveryNCallback call back function for Retriggerable AI Using Retriggerable Counter (http://zone.ni.com/devzone/cda/epd/p/id/2345)

instead of using busy looping for the read result.
But it seems that it only work for the first time,

 Any ideas ?

Thanks

Hey knowhow,

I have a few questions for you:

What programming language example were you looking at on Dev Zone? 
What are you referring to when you mention a "busy loop"?  You were referring to a callback function, which is event driven by default, so I was a little confused.
And just so you know, I downloaded the C# code on to my computer and ran it successfully using a retriggerable input.  What unexpected behavior were you experiencing?
