• How to equalize tcp/ip writing and reading rate?

  I use NI CRIO-9073 and labview 8.6. I am sending & receiving of real-time data to the host (with swicth) pc. This interval of data communication is 8milisec and milisec 10 so how do I equalize my write and read rates for example 8 miliseconds. If I can do it, I can't lose my logging data.

  In fact my real problem is that real time works 8 milliseconds to 20 milisecond (interval) for sending data, but datalos.vi reads 9 milliseconds and it works when RT works in milisec 8, when my reading speed is less than RT sending rate I see that my system is data loss

• Develooping app for Windows Store - writing and reading file: file came from another computer

• Simultaneous digital writing and reading w. measurement interval

  Hi all

  For the last couple days, I've been trying my brain trying to get a program to run.

  I am trying to generate a camera digital 4 output bits then simulatanously count edges mounted on its LSB up to an arbitrary number set by the operator of the program, how the program should be a measure.

  I note, however, that, on a certain edge County number growing (~ 950 or almost), the program crashes. The problem persists even when I remove the function that reads the LSB, although, in this case, accidents occur to a much higher number. What could cause this? Is there a way I can work around this problem?

• Keyboard for blackBerry Smartphones stuck in portrait mode when writing and reading messages

  Hi all

  I really hope you can help me solve my problem. Since a few days, my keyboard is stuck in portrait mode when I'm in the Messages menu. No matter what I do, it cannot switch to see the landscape. I tried to rotate in all directions, but without success. Apart from the Messages menu, the keyboard orientation changes as it should. But at the time wherever I press the Messages button, the display immediately switches to portrait. Apparently I blocked it somehow, but I can't unlock it now. I tried all the options, I changed the sensitivity of the change of the screen, but nothing. It's really boring to write e-mail messages using a SMS keyboard. Can someone give me advice how to restore the display of the landscape keyboard?

  Thank you very much in advance.

  Hi and welcome to the Forums!

  Whenever random strange behaviors creep, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

• How to set and read cookies in adobe edge animate

  Hi all

  I need help with writing and reading cookies using the tip of adobe, is there a way to do I serached internet, but I found something simlliar?

  Thanks in advance

  To test with this plugin in a simple HTML page, you also need to include jQuery itself.

  For example:

  ...

  ...

  There are several different ways that you can load the jQuery.cookie plugin in your composition. Regardless of the method, I recommend loading compositionReady relaxation. It is the trigger that triggers once the composition is ready to play.

  This blog shows a way to load in external .js files:

  http://chrisgannon.WordPress.com/2012/09/01/loading-external-JavaScript-in-Adobe-edge-Anim ate-the-easy-medium.

  Here's how you would apply this method for the jQuery.cookie plugin:

  

  Enter a code similar to this:

  () yepnope
  {
  Nope:]
  ' / path/to/jquery.cookie.js'
  ],

  full: init
  }
  );

  function init() {}

  create initial values of your cookie here

  }

  Who is responsible in the jQuery.cookie plugin.

  It would be for you to create/manipulate data of the cookie as necessary for your needs. Most likely, you would do scroll down to a point in the script where you want the data editable or read, add a trigger, and then insert the necessary code.

• vCO and reading/writing files

  Hello community,

  I am a newbie with vCO, sorry for the basic question perhaps.

  I created a "workflow" for automatic deployment and customization of VMs. job well enough, the model is cloned, sysprep, vCPUs and RAM set and so one. But the final customization tasks is to assign a unique IP address that is in a list in a plain text file. vCO should open the file, take the first IP address in the first line, remove it and close the file (DHCP is not an option). I can open and read the file with the options of '.readall' and a 'player', but which is not exactly what I want. I tried a few '.readline' which translates as "cannot find function readline" and after I I thought to split the entire string that resulted in "no defined split." I really don't know if this is the right way.

  Can someone please guide me in the right direction, perhaps with a few code snippets?

  Thank you very much!

  S.

  OK, here's another example, which reads the entire file into a string, and then use split() for areas exploded in the elements of an array:

  var fr = new FileReader("C://vcoscripts/demo.txt");
  fr.open();
  
  var complete = fr.readAll();
  System.debug("complete: " + complete);
  var lines = new Array();
  lines= complete.split(/\r\n|\r|\n/);
  System.debug("lines: " + lines);
  for (var linenr in lines) {
      var currentLine = lines[linenr];
      System.debug("currentLine: " + currentLine);
      }
  

  With this, you can use methods of standard table (push(), pop()), which might be easier to use.

  The regular expression to split the lines that I got:

  http://StackOverflow.com/questions/1155678/JavaScript-string-newline-character

  (good reading...)

  Edit: I forgot: with Array.strip (), you can remove an element of a table (in your case the IP address used before writing it back to deposit via FileWriter...)

  Kind regards

• DAQmx start and read series vi low bits before actually reading

  I use DAQmx writing to set the bit on a map of 9403. When I set a little high, then try to read this small in a vi subseqeuent little gets low! Both DAQmx Start DAQmx Read screws seem to back the lower wick. How is that supposed to happen? I was certain that bits would not be initialized weak unless the device has been reset.

  I'm guessing that you create a digital output channel, call start, writing and then create as a separate digital input channel and call start-> reading or reading.

  Create the input channel changes the direction of the line.  This happens to commit (which you cross when they if call to start, or read with no departure).  Once the changes of direction, you no longer drive line.  That's why you always read zero.

  You have two options.  You can call read after write (in the task of digital output), or you can have fun with the tristate property.  TriState is a channel DAQmx (DigitalOutput-> Tristate) property.  Aid that it is good enough.

  Two ways to read the value of the line without changing the current state of the row.

• The most effective way to log data and read simultaneously (DAQmx, PDM) high data rates

  Hello
   
  I want to acquire the data of several Modules cDAQ using several chassis to
  high data rates (100 k samples per second if possible). Let's say the measurement time is 10 minutes and we got a large number of channels (40 for example). The measured data is written to a PDM file. I guess, the memory or the HARD disk speed is the limits. For the user, there must be a possibility to view the selection of channels in a graph during the measurement.

  My question: what is the best and most effective way to save and read data at the same time?

  First of all, I use an architecture of producer-consumer and I don't want to write and display the data in the same loop. I expect two possibilities:

  [1] to use the 'DAQmx configure logging.vi' with the operation 'journal and read' to write the data to a PDM file. To display the data in a second loop, I would create a DVR samples documented and 'sent' the DVR for the second loop, where the data will be displayed in a graph (data value reference). This method has the disadvantage that the data of all channels is copied into memory. Correct me if I'm wrong.

  [2] use 'DAQmx configure logging.vi', but only with the "journal" operation to write the data to a PDM file. To view the selected data, I had read a number of samples of the TDMS file in the second loop (I'm currently writing the TDMS file). In this case, I have only one copy data from the selected channels (not), but there will be more HARD drive accesses necessary.

  What is the most effective and efficient solution in this case?

  Are there ways to connect and read data with high frequencies of sampling?

  Thank you for your help.

  You say that the measurement time is 10 minutes. If you have 40 channels and you enjoy all CHs at 100 kHz, it is quite a number of values.

  In this case, I always try to approach under the conditions of use. If a measure is only 10 minutes, I just connect all PDM data and create a graphic module that could be in the same loop of consumers where connect you the data. You can always work on the raw data files big offline afterwards, the extraction of all the information you need (have a look at the product called NI DIAdem: http://www.ni.com/diadem/)

  The main issue is that the user needs to see in the graph (or perhaps a chart can be useful too). Lets say that the graph is 1024 pixels wide. It makes no sense to show multiple data to 1024 points, Yes? Every second will produce you 100 data points k per channel. What is the useful information, which should see your username? It depends on the application. In similar cases, I usually use some kind of data reduction method: I use a moving average (Point by point Mean.VI for example) with a size of the interval of 100. This way you get 100 data points of 1000 per channel every second. If you feed your graph every second with these average values, it will be able to data points in 1024 of the store (as a default) by channel (curve), which is a little more than 10 minutes, so that the user will see the entire measurement.

  So it depends on the frequency at which you send data to the consumer. For example, collect you values 1024 by iteration of the producer and send it to the consumer. Here you can make a normal means calc or a bearing (according to your needs) and he draw a graphic. This way your chart will display only the values of the last 10 seconds...

  Once I programmed some kind of module where I use a chart and not a graph, and the user can specify the interval of the absolute timestamp that is traced. If the data size is larger than the size of the chart in pixels, the module performs an average calculation in order to reduce the number of data points. Of course, if you need to see the raw data, you can specify an interval that is small. It all depends on how you program zoom functions, etc... In my case I hade a rate of 1 Hz, so I just kept all data in RAM limiting the berries to keep 24 hours of data, so that technicians could monitor the system. In your case, given the enormous amount of data, only a file read/write approach can work, if you really need access to all of the RAW data on the fly. But I hope that the values of working capital means will be enough?

• Diffrence between the tablespace is ONLINE and READ WRITE?

  Hi all

  I'm very confused on the tablespace is ONLINE and READ WRITE?

  Some say that if the tablespace is online, this means that its READ WRITE and when its offline then its READ-only.

  So, what is the difference between them:

  ALTER TABLESPACE offline tablespacename; -> done mean READ only now?

  ALTER TABLESPACE tablespacename online; -> is it means its READ WRITE now?

  If Yes, then what is the use of the following command if above 2 commands? :

  ALTER TABLESPACE tablespacename [READ ONLY |] READING WRITING];

  Kind regards

  Confused Ritu

  In addition, when the tablespace is offline, objects belonging to those who are not available for use to users. You wouldn't be able to query for objects in a tablespace offline.

  When the tablespace is read only - no write operation cannot be performed i.e. etc. INSERT/UPDATE/DEL. Oracle says that read-only tablespaces provides a way to protect the historical data so that users cannot modify it. You can drop objects, such as tables or indexes, to a tablespace read-only, but you can't create or modify objects in a tablespace read only

  In order to bring a tablespace OFFLINE to ONLINE - so that it is available to users, you must "ALTER TABLESPACE online tablespacename" command. A tablespace online can be READ ONLY or READ WRITE mode.

• Write and read files 8859_1 but miss char

  Hi all!

  The javadocs are your friend, you know. If you check out the javadoc for InputStream for example:

  http://docs.Oracle.com/javase/7/docs/API/Java/IO/InputStream.html

  Check out the "direct known subclasses. I'm sure you're smart enough to not need more than information to determine what your options are. You just need to know where to get information!

  And of course, there is no one stopping you to create your own stream of input/output 'false' when there is no option :)
