Hi everyone A couple of weeks ago i had the need to put a small suite of applications i made in the tray area, but the VIs i could find to do this wasn't really very intuitive or was lacking the functions i needed. The solution? Another one of these put-your-LabVIEW-app-in-the-tray toolsets .. but this time, a little better wrapped than the example code you can find on NI's site.. ;-) (no offense) So here it is for you to evaluate .. it's not anything near final, and one can always find a number of small features lacking, but hey..it's event based, and its pretty easy to add more events if ever needed :-) Notes: Code is currently for LV8.6 and requires at least .NET Runtime 2.0, but i know for a fact that it runs on Win7 and LV2010.. Installation: Unpack / Extract contained "Notify Icon" folder into your user.lib and refresh palettes or restart LabVIEW.. Examples: Browse into your user.lib -> Notify Icon palette and drag the "NotifyIcon Class Example" VI to your block diagram (or open it by browsing into the "user.lib\Notify Icon\Example" folder) License: Since i made this code in my sparetime, but planned to be using it at work, i've made arrangements with the grand-old-boss and put a BSD License on it.. Feel free to send me any comments / questions AND bugfixes / error-reports Thanks Stinus Well..since FF4 doesn't want to play nice.. here is the code uploaded using good old IE :-/ Notify Icon.zip

They are not the source of your memory leak. The query could be tidied up a bit but with VISA there aren't many options. A slight change with a small advantage would be to build the concatenation at the loop edge (array of strings) then convert to a single string with the bulld string primitive. Real gains can only be made with fixed size buffers and replace elements but then you need all the ancillory capabilities like setting the size of the buffer and the different modes of operation like with the TCPIP primitives to make it generic. I'd leave it alone if it's working. Optimizing the second one is a no brainer, though. Since I don't know what the licence is for the Keithly Vis, I'll just show the alternative solution rather than post the VI.
