Analog Node samples once every 5 secs and transmits straightaway- How do I know data has arrived at the gateway ?
Hi,
My analog node is set to sample at a certain frequency, say once every 5 seconds. How do I know that the data has arrived at the gateway from the VI on my computer ? Is there an event listener for incoming data ? Really appreciate if someone can enlighten me on this. Thank you very much !
Regards,
Xinke
Hello Xinke
Thank you for your post, please correct me if I have misunderstood but from your description it sounds like you are looking to detect that the data is being transferred correctly from your device to the PC.
In the LabVIEW example finder there is a section on DAQmx events under the hardware heading, I recommend that you look here, the title of the example is Acq&Graph Voltage-Int Clk-EveryN&DoneEvent, I also recommend that you play with this vi to see how you can use the events with DAQmx.
Another way to check that your task is functioning correctly would be to create a Boolean indicator for the error status, I have created a small section of code that illustrates this.
If you have any further questions, please get in touch.

my daughter is 12 and i need books that highlight and read out loud, how do i know whick books do that
Regarding the cursor moving on its own, see:
My mouse keeps moving around on its own, as if someone is remotely controlling my Mac!
This is not known behavior of Flashback. To make sure you're not infected, just install any updates that are available in Software Update. For more info on this, see About the Flashback malware.
That e-mail just sounds like a phishing attempt, and trying to open and view the attached zip file is a major error! It probably contains malware. Fortunately for you, it's almost certainly Windows malware, as I've never yet heard of a case of Mac malware being sent via e-mail in this way. But it could happen, so you should never, ever open attachments from people you don't know, especially in such suspicious circumstances!
Finally, I, like etresoft, have never heard of Avira. There's a lot of bad AV software out there, so without knowing more about it, I would agree that it should be removed, using whatever uninstaller is provided by Avira. If you want to use AV software, use either Sophos Anti-Virus for Mac Home Edition or ClamXav. Both are free and excellent.

When I go to a reply window, sometimes it almost looks like there is a little window/box appears (with the 6 dots that allows the size to be changed) It appears to be the cause of the string/code?
On the Web Wiz Forum, < id="gwProxy" ="">< ="ifofjsCall==''jsCall;elsesetTimeout'jsCall',500;" id="jsProxy" ="">
to be added once the reply is posted, to every reply that I make. Safe mode cures it but how do I know which add-on is the problem? I have 25-30 add-ons.Disable all addons by going to Tools -> Addons and clicking the disable button in every entry under Extensions or Plugins panels.
Restart Firefox.
Confirm the problem isnt there.
Enable each addon one by one by going to Tools -> Addons and clicking the enable button in every entry under Extensions or Plugins panels, in such a way that each time you enable ONE addon, you RESTART the browser and see if the problem STILL happens.
AS SOON AS the problem happens, disable the last addon you enabled. That one is the culprit. You can now enable all the others, if needed. -
every time I open my itunes a message saying an unknown error has ocurred with the following number -42110. how can I solve it?
Hello there, lgi00.
It can be so perplexing getting error messages when we are just beginning to launch a program. There is a pretty in depth Knowledge Base article that dives into many of the meanings to particular error numbers. See here:
iTunes: Advanced iTunes Store troubleshooting
http://support.apple.com/kb/TS3297
Under "Specific Conditions and Alert Messages: (Mac OS X / Windows)" there is the following explanation and guidelines to getting that issue resolved:
"Error 3001," "-42110," or "5103"
This alert is related to iTunes Store movie rentals and authorization issues.
Make sure you are using the most recent version of iTunes and QuickTime. They both can be downloaded free of charge.
If your iTunes is up to date, remove the SC Info folder.
Thanks for reaching out to the Apple Support Communities for finding an answer to your question.
Cheers,

I have three iPads and one iPod and one iPhone. How can I message between them without sending the message to all of them. You send the message to your email address but all of them are set up under one account.
You can have a different receiving email in the Messages app on each device : Settings > Messages > Receive At . I'm not sure that there is a different way to have the message only go to one device.

HT2736 How is it delivered and how do I know if has got there?
If I gift an App,....
How do I know it has been delivered and how do I know it has got there?
Do I get an email or message?You can try reaching out to iTunes support and see if they can tell you if a purchased code has been redeemed or not, but I don't know if they track that.
I'm guessing you cannot ask the gift receiver?
