  Hello

  This is the first time that I am unsing an instrument driver... My problem is when I select a channel and to vary the tension of the chain-specific string changes fluctuating default channel and the channel selected... could someone please help me how to solve this problem please.

  Thanks in advance

  Whenever you call the initialization, a reset is performed on the device. It is probably your problem.

  I recommend you to make a loop with a structure of the event.  Build a decent user interface and Structure of the event allows you to send your orders to food.

• Shared data varying variable published network write error

  In my project in real time, on the VI host running on my Windows PC, I try to write in a number of published network shared variables.  All these write operations are successful (which means that I can read them on the RT target, then a cRIO-9012), except for these shared variables network-published with data type defined as Variant.  I'm not sure what is causing the problem.

  I take the table of clusters shown here...

  

  .. .and going through one "in Variant' VI and then subsequently in writing to the shared variable (data type: Variant).  Diagnosis of the failure of the VI in real-time to read the data, I found that variable writing shared on the host VI produced the following error:

  Error - 2147467259 appeared to Variable shared in the PC host TTS CTRL.vi

  Possible reasons:

  LabVIEW: Unspecified error (Hex 0x80004005).
  =========================
  System OR Configuration: Various operating default (Hex 0x80004005).

  This error or warning occurred when writing the following shared Variable:
  Shared \\My Computer\Network Variables\TC trust Array Group - network
  Shared \\128.144.90.143\Network Variables\TC trust Array Group - network

  .. where 128.144.90.143 is the IP address of the PC.

  Any thoughts?

  I saw this post, and when I found myself with no other option, I have redefined the variables in question to the string data type and replaced all the "to variant" and "given Variant of ' functions with functions 'Flatten channel' and"The string Unflatten"respectively.  Initially, it did not work - functions "Chain Unflatten" would produce error 74, until I realized that the "data includes array or string of size? (T)"input on each 'string Unflatten" function must be set to FALSE. Wiring a constant false for each instance of "Unflatten to the string" seems to have corrected the problem.

  I have still no idea why wouldn t Variant.  Shared variables Editor allows to define a variant data type, so I guess it's supposed to?

• Get the value of an enum as a Variant text

  I want to use a group of settings with which sent to another application via DDE link.  The label of each control of the cluster is sent with the value as text.  Using an array of references to the command I get the Label.Text property for each control in the cluster.  The value is presented as a Variant, so I have to convert the data into a string according to the type of data.  I got this connected to a business structure that could convert to a string data type and the data type of the ClassName property.  It works very well for the (trivial) chain, Digital and the ring but I cannot work out how to get the string value of an Enum.  I would have thought that it would be possible that the string value is a part of the data as shown but the picture indicator of variants.

  I would appreciate help with this.

  The attached vi show what I've got so far.  The desired output array is a dummy control to show what I want to get this VI

  Hi Ken,

  See the vi changed please. If that's not enough, please also see the «OpenG» vi´s

• Variant data vs Flattened to string

  Hi all

  I haven't worked a lot with the type of a variant in LabVIEW and after having read about a few items, I wonder what is the fundamental difference between a flattened chain and a variant data type.

  I read somewhere that the variant data types also contain metadata that includes the data type there and again we need to wire the data type to the function 'variant data. Why?

  What is the case of the use of the variant data type? I think essentially to a use case where flattened string cannot do a job which variant data type can do.

  Thank you

  Ritesh

  Use the Set attribute varying function.

  

  

• Variant to the forestay to enter VI

  Hello fellow developers,.

  I would like to ask if anyone knows how to connect a Variant such as terminal connector for my Subvi? I can't find a control of type variant at the moment.

  I used the variant data and unflatten chain and no Refnum for my Subvi.

  Can someone enlighten me?

  Thank you

  Alan.

  

  Sometimes when I'm not able to locate any specific control/indicator, I prefer for the function block (node) on the block diagram of the right click and select 'Create' > 'control' (or 'indicator').

  

• How to convert the Cluster chain

  Here's a VI to convert all the data to a string, and the VI to convert the string to a Variant.  The variant of the data function will convert to your data type.  I use LV 8.2, please rate if this helped you. Thank you.

  -Branson

  Ok. Can open your eyes now.

  From a perspective of profitability, and programmatic perspective what do you see as the main advantage of this method instead to use Unflatten string functions and flatten to string without going through an intermediate Variant? Or, perhaps, flatten to Unflatten/XML to XML functions. In other words, what are the pros and cons of your method as opposed to this method:

  

  An obvious advantage of your method is, clearly, that it is useless to wiring in the type of data you need to do with the chain Unflatten function. Have address you the other concerns?

• Why is a different flat variant in 2012 of LabVIEW and LabVIEW 2011?

  

  When I flatten a variant of this way in 2012 of LabVIEW, the hexagon I get is 1200 8004 0000 0001 0004 0000 0001 0000 0000 0000.  When I do in 2011, it's 1100 8008 0000 0001 0004 0000 0001 0000 0000 0000.

  Why the difference?

  I'm having a flattened cluster that contains a variance between executables in two different versions of LabVIEW by using TCP and I get an error on the unflatten of the chain.

  This behavior is by design. Now, we include the version number in the flattened chain so that we can change/add to the representation in the future, and new versions of LabVIEW will be always able to read flattened strings that have been flattened in the past.

  If you want to flatten a Variant to an older version of LabVIEW, you can use \Utility\VariantFlattenExp.vi.  It must be a version number under hexagonal - to flatten for the 2011 version, you used above, switch to 11008008 in hexadecimal.  If you group for this version, it will be able to be read by versions 2011, 2012, and all future.

• Size in bytes variant of (in memory)?

  Hi all

  Is there an elegant/effective way to get the size in bytes in memory of a Variant? Or at least an estimate?

  I have a variant of "index" that grows and shrinks under certain conditions, during execution, and I would check occasionally in the size of the memory of it, at least approximately.

  I only found two ways to do this, the two are less than optimal: "Flatten to a string', followed by 'length of the string' or 'binary writing' followed 'file-size.

  This code executes on a real-time controller headless. This means that the memory is limited and disk writes put a lot of resources (relatively) to run.  Flattening in chain makes a full copy, write to the disk using the disk i/o.

  I hope that someone here has a better suggestion... I saw a variant of "indicator" for the property or invoke node options without finding likely candidates...

  All suggestions are welcome, however, "do not use the variants' is not useful. Much time has been spent trying to find another way to solve the problem and the variant was the only effective and feasible solution despite the current question/problem.

  Thank you

  Q

  At least in LabVIEW 2011, Type-casting does not allow 'variant' like the thread of entry, he breaks the exit, even with the entry of 'type' as U8 array... I missed something?

  Also, Yes, I looked in the variant of the lib myself and see no way to get this number... looks like it must be an operation relatively inexpensive at a certain low level... I guess I can ask OR if they / can to provide this feature to call me...

  With a real example - variant previously generated and saved in the file (the binary file size ~1.5MB), it takes about 947 (average 10) ms to flatten to a string and get the length of the string. (not counting the binary load to the variant of course)... and it's 100% cpu... It's far from ideal to say the least...

• If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore all changes since the first full file

  If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore the file with any changes made since the full backup first file...

  If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

  As you can see that these certificates are chained-

  OpenSSL verify CAfile - intermediate.pem issuer.pem
  Intermediate.PEM: OK

  However, after the importation of the issuer.pem, when I try to import intermediate.pem, FF gives.

  "Is not a certificate authority certificate, so it cannot be imported into the list of certificate authority."

  I have no idea what you're up to, but if these two certificates are supposed to be Cert CA, none of them have defined appropriate extension:

  X509v3 extensions:

  X509v3 Basic Constraints:
   CA:TRUE
  

  It is advisable to also specify a Point of Distribution CRL or an OCSP URL.
  If I issue certs today, I wouldn't pick 256 as hash algorithm SHA - 2, SHA - 1.

• Why is my mail downloads enter this obscure chain of records?  / Library/containers/com. Apple.Mail/Data/Library/Mail downloads.

  I've had trouble finding my mail app downloads.  First of all, they won't in the 'Mail download' folder located in my Finder window.  Sometimes they are found in the "Downloads" folder  Other times, I can't immediately find their.  But if I search the name of the file, I noticed that my downloads in my mail application will in a download folder.  But this case is dark, buried somewhere deep in a series of folders.  Here is the chain of records for a recently downloaded file: downloads/F6320D5C-E169-47E8-9A09-00c408F1422D of tlynch/library/containers/com.apple.mail/data/library/mail.

  When I look in this folder downloads deep within this chain (and from com.apple.mail...), I find that some first downloads have been stored there directly.  But there are about two and a half years each downloaded file started being placed in a separate folder.  And the names of these folders are a long string of 32 alphanumeric characters.

  Are these folders the actual location of the files?  I can remove them?

  Can I reset the download destination? The pointer to the location of storage in the messaging application has been corrupted? Or I need to reinstall the program?

  Thanks for your help.

  This obscure folder structure is the usual place for downloading attachments in the Mail and most other e-mail clients.

  When you choose 'Download' the attachment, the file will be saved by default to the location defined in Mail-> Preferences-> general.

  Does anyone know why I would double in pictures pictures that vary considerably in size? Who is the likely cause?

  If you see this by snooping directly in the photo library file, are not!

  Photos is essentially a database program. The one and the only way to manage images in the library is via the interface of Photos, or you will corrupt the database.

  In addition to store the original files (if you do not ckoose to keep a local library optimized), pictures also maintains smaller, miniature to speed up the loading of the different images.

  You use IPHOTOS or PHOTOS and what version of the operating system.

  You can have several libraries in IPHOTOS and PICTURES (in the pictures that only your library designated system is synchronized with other devices via ICLOUD).     You can split the libraries of useful information - like a vacation, family events, pictures of your pets.

• Why wireless speed so vary?

  I have a Qosmio F20 - wireless card is Intel PRO Wireless 2200BG, and it works at up to 54 Mbps with my Netgear wireless router.

  However, the speed varies - sometimes the 54 Mbps
  I want to, but sometimes, 36 / 24 / 2 or even just 1 Mbit/s. Strangely, WindowsXP (actually MCE 2005) says always the signal is "EXCELLENT".

  So why the speed decreases? It can vary from a couple of times per minute.

  Note that this happends even if I'm in the 10 to 15 feet of the router and did not happen with my IBM Thinkpad.

  THANKS FOR ANY HELP / SUGGESTIONS.
