VI Method->Get Lock State Problem

[keiran]

When I want to Get some VI's Lock State Programmly, I found some VI's Lock state is "Invalid Lock State", so what this "Invalid Lock State" mean? It's not locked at all! why labview treat it as Not locked state? what the difference between "invalid Lock State" and "Not Locked"?

"invalid Lock State" representing value 0 is just a wildcard with no meaning.
