• How to detect a Variant empty?

  I get an error when my application passes a variant vacuum (as determined by the probe) to a variant of the function Data. The variant is a Global Variable that has not yet been initialized. I need to avoid calling the variant of the function of data as long as the variant is empty.

  How to detect that a variant is empty? I can't find a function or constant that will help me to do this.

  LabView 2010 is pretty inconsistent about how empty variables of different types are detected. How is there aren't any detection methods of vacuum for each type of data? Why are not always done in the same way?

  You can right click on one of the connectors on a service of alternative variants and select create constant.  This will create a small empty box of purple.  Then you can compare your Variant that and if it is empty, the comparison will be true.

• How to detect fraud sites on the net

  in fact, I came to know websites are offering you opportunities to earn money on the internet by clicking on the sites for example 'two Dollar click'. I want you please teach me how to detect its authentication and its evidence.

  Thank you

  The short answer is, "if it sounds too good to be true, it probably is." Any site that promises you money easy to 'make things you already all days' or 'just by ' is likely to be a scam waiting to be discovered.  The same goes for any flavor of 'Go this expensive piece of equipment for only a few dollars' or ' work from home and make thousands of dollars.

  There are dozens of these sites that go upwards and downwards and save it under a new name every day so it's really not anything to sure to check a site and determine if it is a scam or not.  Common sense is your best guide.  The only "secret: 'this scammer really knows how to separate a fool and his money access."

  Hello

  I need to know my PC if some executables RT runs on the remote computer RT (SMU-8133).
  Y at - it anyway how to detect in LabVIEW, if an application is running in real time and possibly only one?

  Thank you very much.

  The important point is that call a distance VI in this way, you assume that the VI is already in memory. In this case, you don't have to give a full path, just the name of the VI.

• How to detect what causing my hard drive space increase?

  Hello

  My space on the hard disk increases daily 100 MB how to detect the causes of this increase in my hard drive.

  Thanks for your help

  Hello

  My space on the hard disk increases daily 100 MB how to detect the causes of this increase in my hard drive.

  Thanks for your help

  Can be any number of things.  One possibility is the restoration of the system, which, by default, uses up to 12% of your hard drive.  An older version of Zone Alarm (6.5) creates very large files which have been followed by SR (http://bertk.mvps.org/html/tips.html#16 ).  In general, the default should be changed so that the space allocated to the SR should be limited to 1 GB (seehttp://bertk.mvps.org/html/diskspace.html ).

  Rather just guessing, download and run (free) JDiskReport , allowing you to know what is too much space.  Once you know, after return to get advice on how to deal with it.

• How to detect if Bis - B is by carrier or Wi - Fi by programming

  How to detect if the BIS data traffic is routed via the operator network or Wi - Fi. Looking logo BB points, we can see that it will be close to seeing Wi - Fi if data are routed via Wi - Fi and close to the signal indicator carrier if the data is routed via the data network of the carrier.

  Is there a way to detect that programmatically?

  No, I don't know a way to affect the transport, so I would say turn off wifi would be the only solution.

• How to detect BIS support the change?

  Hello world

  I work and test network events manages the real device. I tried to detect the moment where we get actually BIS taken in charge and when we lose it really. Whenever you have granted with a new RIM service, a network event is launched and captured by your camera in the eventOccured() of the GlobalEventListener interface method.

  When I did not warn service RIM yet and I subscribe to a RIM service can I get BIS support channel at the same time. You can send an http request via the BIS mode then and it will pass through. Instead if you do not inform service RIM of your HTTP via BIS will fail and you will have to try again via another channel like WAP for example.

  My question is: How do I know if I just got with the support of channel BIS? There are some methods such as

  CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_BIS_B)
  

  But this always return the same answer: cover just enough even when you're not on granted with the support of BIS.

  So, if anyone knows how to detect this status change, I would be very grateful to meet with her

  Thanks in advance for your answers.

• NFC - how to detect the disconnection?

  Repost - it was in the wrong forum. :

  Just get started with the development of the NFC.

  I've been through the examples and am able to read basic NDEF tags.

  The only thing I don't see is how to detect where the NFC tag disappeared.

  Y at - it a reminder or another trigger?

  Or I will just try to do an operation (read, write, etc.) and then capture the execption?

  Thank you

  Richard

  Hi, you are right that there is no reminder of this event (tag moves out of the field). As you suggest, after detecting the tag in the box, you must handle errors that come from reading or writing to it.

• How to detect the compatibility mode on BB 9530

  Hi guys '

  My application works fine when compalibility mode is disabled on BB 9530 storm.

  But this (compalibility mode) mode is activated after the downloaded application.

  I want to detect it as compalibility mode is disabled or enabled.

  How to detect?

  Thank you guys

  You can detect if your Application is in compatibility mode or not by checking

  yourApp.isInTouchCompatibilityMode()
  

  Where "Yourapplication" is an instance of Application or UiApplication.

  You can also check your app starts in native mode by editing the file .jad, as shown in this article: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800719/What_Is...
