The silver controls have enough bugs that I just shy away from them.

Proud to say that I've progressed beyond knowing just enough to be dangerous. I now know enough to know that I have no clue about anything at all.

There's no silver bullet for that...

Reproduced in 2011 SP1.

It works well to replace it with empty silver array and silver String array, just not the numeric array. I assume it has something to do with trying to move/translate the values. Since you dont have the numeric array in Modern i cant reproduce it with those.

Hi all,


The CAR that DFGray originally submitted has been fixed in LabVIEW 2015! You can find a link to download here.
