do nothing

[mrbean]

I keep encountering situations in my code where I'd like to do something "IF" a certain condition is met.  However, if that condition is not met, I don't want to do anything.  My problem arises when I (in the positive IF case) am in some type of loop and I want to act upon an item that is part of a shift register or is in a tunnel.  If I'm in the FALSE case, I don't want to add to my array, or increment a counter, etc.  How do I implement a "Do nothing" yet satisfy my tunnels?

You can use a shift register and a Build Array function to selectively add items to your Resource Names array.  Here is a screenshot of how I modified your code to accomplish this:

In the False case of the Case Structure, the 1D array just gets passed through without modification. 

I hope this helps...this is a very common techique to selectively build arrays of items in a case structure inside a loop.

When I saw the title to this thread, I figured it was right up my alley.  I was right.

Here is a vi that does nothing:
