    We all have those. This is one reason why people are afraid of xcontrols. I think there's some code base that everyone's afraid to touch: https://forums.ni.com/t5/LabVIEW/XControl-quot-Data-Change-quot-Event-only-fires-when-different/td-p/418552/page/2

    See, whenever I have a bug in my code where "it works on my machine" I just build a debug version of the executable, transfer it to the computer in question, set some breakpoints and discover that there's some unexpected combination of things that I never accounted for. It's then usually just a matter of putting in a retry or upstream validation and the bug is solved. I really wish the AEs could do something like that. I feel like it would solve 70% of my problems in 20% of the time. I feel like the other method of making random modifications to my code so the bug magically goes away really does us both a disservice because the bug is going to come back for no reason for both me and a few other customers.

    I've been a little more active in filing service requests this year. I have: 3 open 1 RMA 3 CARs 12 created in the last 12 months Thanks NI for giving me a resource to help me through the tough spots. I'm never leaving SSP if I can avoid it. Thanks everyone else for all the CARs you generate before I have to generate my own reproduce case.

    Are you using async VIs? I find it unlikely you have some refnums getting autocleaned unless you do. You have a case where the com works and one where it doesn't. Try and figure out what intermediary step breaks the functionality. Can you read one byte at a time until you get the termination character? Maybe someone with more telnet experience can weigh in. I'm not clear why you wouldn't be getting an error. In debugging you have to check everything (error codes, refnum IDs, counters of how often a given subVI runs, etc) to see the smoke to tell you where the fire is. You might have to modify VIs you received from outside sources.

    I hate the silent mutation. I wrote this idea a while back: https://forums.ni.com/t5/LabVIEW-Idea-Exchange/Deleting-an-enum-element-from-a-type-def-should-cause-a-broken/idi-p/1763158 I'm curious what actions specifically default the value. What version are you using? 2014 helped but I know there's still some mutation going on with the case structures now.

    Has anyone seen Network stream socket error -1967390704? I see this error every now and then on various computers. LabVIEW hangs in the task bar and I have to for quit and then I have to restart the NI PSP service and everything is OK. I have a service ticket open but we're sort of running out of ideas for how to reproduce the problem or on what data we can gather when I see this error.

    For follow up, I was able to create a batch file: netsh advfirewall firewall add rule name=%1 dir=in program=%2 action=allow and in my installer I have these command line arguments "Allow MyApp" "[INSTALLDIR]MyApp.exe"

    I've always used Zebra designer to convert my logos to ZPL.

    I keep coming to computers and I guess the user didn't approve the exception or something because they're getting an error 56 when the app opens a TCP connection. I'm looking for ways to avoid this. Some ideas: Autoapprove the exception as part of installation Is there a way to keep prompting them until they approve the exception or close the app Maybe a command line I can send them if they say they are seeing error 56?

    It works with debug on too. If I try and probe, I see a memory increase and UI slowness.

    FYI, I just ran a quick experiment (see code below). Watching profiler and task manager, it appears the compiler is smart enough not to copy the string.

    Maybe VIM could help?
  13. infinitenothing
    So, in a case like channel wires, they implement their end typing with a right click dialog (see below) If you want it more automagical, you'll need a VIM with a type specialization structure (see second snip, requires lapdog) for specific types

    Linear algebra is very useful for control theory, simulation, and machine learning. I posted what I thought was a math problem a while back. I wasn't really sure what the domain was though.

    GigE=125MB/s. Out of curiousity is there a reason you don't want to use IMAQdx? I've never used activeX/dotNet for image acquisition.

    Can I submit range requests? Your group can do what IANA does for IP ports. Also, I use the "Custom Error Code" feature of the error ring which uses the <ERR> tag which removes the need to distribute the XML error file with the executable and allows for descriptions that can help you debug "There's no case for an input of %d"

    The original Sony rootkit was on a CD ROM How's that for provenance? I'm having a hard time seeing why usbkill is a concern. Why would an IT policy stop a motivated vandal?
  18. infinitenothing
    FYI, the usb drives use DVD-ROM drivers and are read only.

    NextLabVIEWStand confirmed!

    I'm guessing they are going to handle that by having the option of an HTML UI. There was some hinting of LabVIEW to javascript in prior keynotes.

    Maybe draw a system diagram. Possibly some state diagrams if applicable. A queued state machine is probably a good choice for some of your loops.

    Minor nitpick but the combobox border is too thick

    Check out the example here:C:\Program Files (x86)\National Instruments\LabVIEW 20xx\examples\DAQmx\Analog Output\Voltage - Continuous Output.vi

    I just saw this post. That's a VI snippet. You can drag it (might have to save it to disk first?) and drop it onto your block diagram. You'll get all the cases (both true and false). The "pen" false case just has the pink wire wired through (don't make any changes) and the "previous pen" false case looks like the image below As for getting the "mouse status", maybe try acquire input data.vi

    You can also use this NI function to get a list of enums strings from an enum: http://zone.ni.com/reference/en-XX/help/371361M-01/glang/get_numeric_information/
