LabVIEW 2011 Silver Palette

[LabBEAN]

Regarding my experiment with the 2-D Array of Round Color Box (Silver):  Open VI Reference is the affected function.  If I can perform 1000 open-then-close reference actions per second with the Modern round color boxes on the panel, I can only do 100 with the Silver.  I set the experiment up with tabs:  If I switch to the tab with a 2-D array of Modern color boxes, everthing works as expected.  If I switch to the tab with a 2-D array of Silver round color boxes, screen updates suffer.  If I add an Open VI Reference and Close Reference in each loop cycle, application performance suffers.  If you need to rapidly open and close VI references, then do not use Silver color boxes.  Could be true for other Silver controls.

LabBEAN - We're not able to reproduce the performance problem you're seeing. Would you be willing to send us your VIs?

[LabBEAN]

Christina - Sure thing.  I started a thread on it here and provided examples.

Having spent all afternoon trying to debug a colleagues VI that kept crashing when buttons were pressed, I noticed that he was using Silver Control buttons.

I replaced these with buttons from the standard library and the application now runs reliably.

The silver controls look quite nice but I think I will be avoiding them for the time being!!

I maybe be experiencing a similar issue. Every once in a while when I press a button LabVIEW crashes. I had not consider the Silver Palette, but I will keep this in mind if it happens again. Thanks

If anyone experiences repeatable problems that are demonstrably the result of the use of Silver Controls, it would be great if they could share their code for those at NI to be able to get to the bottom of any issues.

LabBEAN did precisely that a few posts above with his link to a forum thread.

Thoric,

That's always the problem with inconsistent bugs. I will post a link if I can repeat the issue. It has not surfaced in about a month of working on the code.

I have sent a report to NI regarding my findings already.

My problem was completely repeatable with a colleagues VI running in parrallel with a LV application in development mode.

I have written some small VI's to try and give NI an example, but this does not crash. I am not sure what the specific instances needed to cause the behaviour. I can only say that we unluckily have them!!

[Thoric]

Great to hear guys

We have found a significant issue with creating Silver ring controls from block diagram terminals and constants. If the resulting ring is not a U16 numeric type, it will not be formed properly, which can lead to erroneous behavior and failures when trying to save a VI.

I have not yet received a report of reproducible issues with Silver buttons, however, so do please continue to provide us with any information you can to help us, especially submitting any crash reports you encounter.
