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?

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.

Our systems engineering group has a table where they keep track of projects/toolkits, error code range assigned, and the project owner. When you need custom error codes for your project you will get "assigned" the next chunk of 50 error code values on the list. These error codes are now yours to do with as you please.

I don't have to manage this list so I can't speak to the drawbacks there but from the perspective of someone who needs to use the system it's pretty nice. I sent a message to someone asking what error codes I should be using and they sent me a link to the internal list, added my name, and told me what error codes to use.

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?

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

Dear Infinitenothing!

I would like to ask for some help. What is under the False value?

Thank you very much.

I attach the vi.

PEN.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:

I'm not sure but does convolution rotate the array so it wraps around? If so, there might be some issues with a nonsinusoid. In my case, when the waveforms are perfectly aligned it would be comparing the first signal's segment that looks like this: / to the second signals segment that looks like this: \ making for a bad match.

Doing a replace on the endpoints making the readers to writers and vice versa (no rewiring) made no difference for me. It all works fine.

Yeah, works fine once you figure out the right parts. Here's example code. You'll want to run one exe with the boolean true and the other with it set false.

Huh, not sure why the snipping tool isn't working. I got a peek value as shown in the upper right of the graph but that peak doesn't seem to correspond with anything. I backsaved the projected the old fashioned way and attached it as a zip
