I am using Labview 8.2, and this post is regarding the 3D Picture Control.
I am wanting to make use of the "Find Object" VI to either return a reference to a named object, or otherwise determine that it does not exist yet. However, if I call it with the name of an object that doesn't exist yet (i.e. just any random string), it returns an error message that arises from the attempt to release a queue (the reference to which gets lost when crossing a zero-iteration For Loop's tunnels), instead of an error message that says "Object not found" which I would find much more useful. With a simple modification of the "Find Object.vi" function, this behaviour can be changed, by replacing the For Loop's tunnels with shift registers.
The problem with the current function is that the error is not an intentionally thrown error, rather just the result of the queue's refnum being set to the default 0 as it "exits" the For Loop, since in the situation that an object is not found, the code passes a 0 to the
N terminal.
The attached images show the problematic code and the simple modification
