• Are published network shared variable write & read Atomic actions

  Hello

  I have a very basic question about shered (published network) variable.

  I think I know the answer already, but since I couldn't find in my documentation, I thought that it is more prudent to request...

  Are reading and writing on a shared variable of stocks Atomic?

  To be more precise: on my target real time I create an array with data (each element being the configuration item or a cluster containing name, value, and type) and when the table is finished I am this store in a published network shared variable.

  On my host (Windows), I'm voting (in a loop) until the table contains at least 1 item, when this is true I'm parsing all the elements in the table.

  Is there a chance that, reading of the shared variable, the table contains a subset of the original painting on RT target (i.e. the action of reading takes place while writing is still ongoing).

  Or is the action of reading delayed until the write is completed? (i.e. both write and read actions are atomic even over the network)

  I think the latter is true but not could find no evidence in the documentation.

  Kind regards

  Hello Rob,

  Yes, you can access the entire value, data type - you use both. For the table data type, the integer value is actually the full picture. So, Yes, you can see reading and writing as Atomic actions.

  But, on the other hand, you can lose data if the RT system rewrites the variable before the host had the time to read. To avoid this, you can enable buffering for the variable. See the following links for more information:

  http://www.NI.com/white-paper/4679/en

  http://zone.NI.com/reference/en-XX/help/371361H-01/lvconcepts/buffering_data/

  Finally, you can also activate a FIFO RT on your target RT if you need to send data through the variable in a deterministic section of the RT. See also, more information:

• Keyword not valid non-atome

  Hello

  I use TB 24.7.0.
  Something weird is happening today with tuberculosis.
  I have some configuration of filters to assign specific tags for the incoming mails. Everything was fine until today.
  What is more strange is that I didn't tamper with all filters, options or anything today or recently.
  I guess that is not yet what triggers, but certainly when a new message arrives, or when I just browse even though records emails, tags are suddenly deleted, and all e-mails have 0 tags.
  The same behavior is also in safe mode.

  I tried to compact the Inbox folder, and I got an error like this:
  The current operation on "Inbox" has failed. The e-mail server for the account [email protected] responded: invalid non-atome 'blablabla' keyword (this is one of the tags that I use)
  I understand there's a problem with Gmail, but the tags are stored on Gmail? I have although they where to store locally.

  If someone has an idea why this phenomenon happens, or have any trouble, let me know.

  Thank you
  Alex

  Thanks Matt,

  Seems that Gmail does not like my tag IDs. I got something like:
  "[category] _tagname ' and the characters '[' and '] ' are not valid.
  I used 3 years like that, I do not understand why now are suddenly invalid.
  In any case, I created them again with only alphanumeric characters (just rename does not work) and change my filtering with the new tags. Now works correctly.
  Of course, all of my old emails is remained tagged with the old tags. Well, a minor inconvenience, I'm just glad works.

  Good day to you all,.

• How can I get rid of the 'information atoms '?

  I downloaded the latest version of Firefox and I noticed that I am re-directed to other sites sponsored by 'information atoms '.

  I called myself removing elsewhere seeking troubleshooting tips. You told me to go in the registry ("regedit") editor and search for files and delete them. I did and I always redirected to the websites of atoms and see the context menus on fields where I am typing in a keyword search.

  This has happened since I Firefox. None of the other browsers on my PC had this.

  I just want to know how to get rid once and for all.

  It is not in my list of programs, does not show up on research in my menu START. He is buried somewhere in my registry settings.

  The answer I wanted to - and should have understood myself - was to go to the Control Panel programs and features and just UNINSTALL it! That solved my problem.

• Pavilion X 2 detach, 10.1 inch: upgrade RAM, Pavilion X 2 loose Atom Z8500

  Hi, I'm on HP Pavilion X 2 detach, 10.1 inch, atom Z8500

  I have 2 GB of RAM

  What type of upgrade I can implement? Upgrade to 8 GB of RAM, perhaps, or anything like that?

  Thank you

  Hello

  It's a HP Pavilion x 2-10-n138tu:

  http://support.HP.com/SG-en/document/c04855773

  It has CPU, RAM, HARD drive... on board means soldered to the motherboard. Only one option: purchase new machine because buying another motherboard can cost more (cost of Council and labour).

  It has 1 microSD card reader, you can use this to increade more storage. Very safe to use the card of 64 GB.

  Kind regards.

• NB305 with Atom N550 - Europe

  Anyone know when can we expect new NB305 with Atom N550 in Europe? Any rumor?

  Hey Buddy,

  When he of done ;)

  Seriously, it's not easy to say you can only wait for him, but perhaps a certified maintainer can give you what s can official response because they can get in touch with Toshiba.

  If you request an ASP page, it would be good to hear some comments from you. :)

• NB105 TEMPERATURE OF ATOM

  Hi all!!
  The temperature at which it produces the atom in my NB exceeds the 90 degrees centigrade, according to Core Temp and the lower part starts to boil. Is this normal?
  Thank you.

  I've never seen such high temperatures, I use a program called Notebook Hardware Control and my temp is showing that CPU Temp 48 degrees C, HDD temp 38 degrees C even after 12 hours of use.

• base handling integer does not not on HP first Calc?

  I am a new user of the first HP Calculator.  Suite page 585 of the manual on the manipulations of integer.  I've entered a number #100001100 b and to display its value in hexadecimal form or decimation.  I scroll to the top to select.  Then I press the passage, the base key (directly to the right of 3), but I don't get the whole edit dialog box.  I have an input # as she waits for a new number to register.

  What I am doing wrong?

  After that I got the same problem, to update my firmware, I found that the following procedure works.

  1. manually put your first update the firmware by holding down mode button Symb when executing a reset of a paper clip.  You will see 'First HP Recovery Mode' at the top of the screen.

  2. important: connect the first USB 2.0 port that is closer to your motherboard as possible.  USB ports that are connected by an extension or a hub often will fail, even if it is a powered hub.  USB 3 ports have also been known to fail.

  3. navigate in Windows Explorer to the folder of installation of the connectivity Kit.  In 32-bit Winows 7, here it is:

  "C:\Program Hewlett-Packard HP Connectivity Kit.

  4. run the "Updater.exe" program directly from this folder.

  It should work.  If this isn't the case, I can only suggest to try another computer.  Some people have reported having no success with a computer, then the success with another.

• HP Mini Atom N2600 1104: why the OS 32-bit (Windows 7 Pro)?

  I just bought a HP Mini 1104 (Atom N2600 processor).  The architecture is 64-bit capable.  Why it comes with a 32-bit version of Windows 7?  I think that the 64 bit version of Windows 7 would be a more natural match.  Is there some extremely effective in disk space, speed, or power draw using the 32-bit version of Windows 7?

  Thank you

  -Ryan

  Hey, Ryan:

  A 64 bit OS requires more disk space and memory to run a 32 bit OS.  Not double, but more.

  Unless you have 64-bit programs, there is no advantage in having a 64 bit installed - OS, especially if the maximum memory you can install is only 2 GB.

  The processor is capable of 64-bit, but it does that of up to 2 GB of memory.

  On your laptop, you're better off sticking to an OS 32-bit for the aforementioned reasons.

  I even think that somewhere on this forum someone has tried to install W7 x 64 on their mini with the N2600 and he would not go because of an incompatible hardware error message.

  I don't get that because the processor is normally the only keeper there.

• What is Windows 64 - bit OS Runj on The Atom?

  I see the files listed in the section update files for the NB205-N311/W which are for versions Windows 32 and 64-bit Windows. What is this means that 64 bit versions of Windows 7, Vista and XP will install on the NB205-N311/W?

  I know that Toshiba U.S. Announces 64-bit drivers in their download section, but the ATOM processor is a 32-bit processor, it cannot run the 64 bit OS. Now with NB200/NB205s or we receive Hyper-threading :)

• Convert integer to string and show two numbers

  Hello

  How can I convert an integer to a string?

  StationGlobals.MyInteger is 1.

  With the help of Str (StationGlobals.MyInteger) must convert to "01" instead of only 1.

  How is that possible?

  THX

  Thanks for the screenshot.

  I took the format string "%.2i" in my function str() and now have numbers here too 2.

• Determine if an integer is a floating-point number

  I want to create a program that when an integer is entered in the digital constant, a floating-point number with zeros to the right of the decimal point lights up the LED on the front panel. The LED remains off for any other floating-point number. I know I want to use a ride to the nearest function, but don't know where to go from there.

  You want to say CONTROL, right?

  You just need a type of rounding.  No matter if round you upwards or downwards.  If you just around and then compare the entry to the rounded value.  If they are equal, you turn on your LED.  So all you need is a digital control, 2 functions, and a boolean flag.

• Entire scan of long integer modifier

  Hello

  I'm looking for likely the format of a variable of integer type

  For example:

  int nb;

  NB = 1;

  Change the content of the variable nb 1 at 000001

  OK, so the problem is formatting of integers in specified formats.

  As you can see the search Help for the Fmt function, you use a specifier of evil: at the index of the loop, this is an integer then you should use instead of %s %d. here you implicitly declare YYYY DD, MM, are strings, so the correct format string is the following:

  < %s="" %s="" %s="" %d="" [w6p0] »,="" mm,="" jj,="" aaaa,="">

  I leave to you to interpret the symbols I used based on the help page I linked.

• [ETA: posted in the wrong forum, sorry! will transfer in the relevant forum] playback of samples: atomicity of critical section?

  Hi all

  I have the following situation:
  -a single thread (T1) is constantly reading from a USB NI 9229 module samples into a local buffer and copying a table a (44100 Hz)
  -another thread (T2) is waiting for an order and then copy a lot of A 44100 samples to a local array variable and make a calculation with them
  -array A is protected in a critical section (T1 and T2 enter the critical section when you work with A directly and then leave)

  How "atomic" is the device samples in my array A reading? That is, it is guaranteed that the protection of the critical section in a way that at the time T2 accesses A, T1 has finished writing 44100 samples in there?
  Or should I register with DAQmxRegisterEveryNSamplesEvent() a reminder that 1) reads 44100 samples, 2) warns T2 that the batch is complete and available?

  Thank you in advance!

  As I understand the situation, the answer should be "Yes": the table is protected until you exit the critical section.

  But may I suggest an alternative, perhaps simpler approach?

  If you configure a thread safe queue 44100 elements that ignores old items, with T1 that fills on top, T2 can freely read the queue without disturbing T1, seen available the most recent series of data in any time.

• integer in a textbox

  Hello

  I use Diadem 2012, and I have a problem to acquire a number in a text box.

  IM new tiara and programming so please excuse me if my questions seem essential

  My textbox is set up like this:

  Variable: tolerance

  VariableColIndex 1

  VariableRowIndex 1

  In Edit/Variables, I selected:

  type: Integer

  Storage mode: scalar

  I received an error message when I run the dialog box:

  Cannot bind to the variable dialog box (s):

  tolerance: you have specified this variable with an invalid type. It's the good type: Variant

  I guess I should be able to put a whole one here?

  --------------------------------

  In the case, I use the type variant

  I define in the script: GlobalDim ('tolerance')

  But when I write a number it return me '5' (the text I guess) and not the number 5.

  What should I do?

  Also there is another way to use data beteen dialogbox and script the use of GlobalDim in the script and set the variable manually in the dialog box?

  Best regards

  Frédéric

  Hi Fred,.

  I'm sorry, that the SUDialogs text box returns a string, so you'll need to use the CLng() command in the SUDialog to convert the value of the variable 'Tolerance' to a variant of subtype string to a variant of subtype integer.  You can do this in the case of LoseFocus in the text box or the Terminate event of the SUDialog.

  Alternatively, you can declare an explicit data typed variable with OdsValAlloc() or by loading a file *.vas with UserVarCompile(), you can associate a variable of integer type instead of a variable of type variant in the text box, then the SUDialog would be automatically coerce the string returned by the entire text box.  In this case the SUDialog also pop up would be a dialog box error you can't control if the user enters a non-integer value in the text box.
