The loss of data when disable call forward

• Synchronize data when you call another VI

  Saying: I A.i and B.vi called B. I want to display a waveform to A and B collects data in a while loop.

  The question is how the waveform is updated in real time, then B is running? I tried global variables, but looks A.i isn't in the thread when you call B, so the data may not switch to A real-time.

  Any suggestions?

  You want to search for ' Producer/consumer' of info on this design pattern. It consists of a producer who share data using a Motor of Action or a queue to pass data between threads.

  Another approach might be to use a control reference for waveform display (table or graph) and use 'the 'Value' property to write to the display in a manner SIMILAR to the writing comes to the Terminal.

• Is there loss of data when I have other operations at an event?

  Hello. I am a new user to NOR-DAQ.

  Now I develop a sampling program HAVE continuous for the NI USB-6229 case.

  The environment settings are 8 channels under 2 kHz sampling frequency. In the program

  I need to save the data in a csv file each time than in quite awhile, let's 500ms, through the 'event '.

  mechanism. I tested that it takes about 32 ~ 48ms to write the data of 500 ms.

  This 'event' appears as a software interrupt for me so I was wondering if the DAQ hardware

  continues to record new data while I perform the write operation in the case?

  Or put in another way, when I set up the task of sampling with the function

  "DAQmxCfgSampClkTiming", the "sampsPerChanToAcquire" parameter is described in

  be used as a factor to determine the size of buffer. Is this the intended "AI FIFO" buffer buffer

  by the "M series user manual? This means that if I put it to an appropriate value data

  will always go in this buffer first and then read by the computer, so if the transfer is fast

  enough, there is no data loss?

  Thank you in advance.

  Data are recorded by the data acquisition apparatus and stored in the FIFO buffer.  The reading VI DAQmx then takes the amount of data specified on the FIFO and brings the data in your program level.  So as long as your buffer is large enough, you won't lose any data.

  Here are some other suggestions.

  Focus on the architecture of producer/consumer .  It is a way to put writing files in another thread to process and record data at the same time.

  Lean on the function TDMS flow in the DAQmx palette.  It is a way to bypass the program level and get a log file of the data.  The data format will be PDM and not a CSV file.  But there is a plugin to read the TDMS files in Excel.

• Loss of data when you save it to a file?

  Hello

  I have problems with my data recording. I acquire at 2.5 MHz for 5 seconds and when I view it I don't see 1.2 s data, if you use a single channel, or unless, as 0.4 s data, when getting the 8 channels.

  My vi is attached and also a picture of him. To analyze it, I use "TDMS File Viewer" (PDM - File Viewer.vi):

  Attached, it is also a picture of the file viewer. Check the number of samples (225000) and the time when it was taken (19/11/2008 16:14:30.423) and (2008-11-19 16:14:31.362). With a 2.5 MHz, there should be much more samples than what is there...  The last sample (which was not shown in the photo) is time (19/11/2008 16:14:30.513), only 0.1 s after having begun to acquire data.

  Is the problem with the queue? If this is not the case, why are data not saved?

  Thanks for the help,

  Rafael

  Your consumption (bottom)) thread will be scuttled as soon the producer (top) out of wire. Leave the upper loop kills the queue; Dequeue item returns an error, and writing to a file won't do anything if there is an error on the entry. If all the remaining items in the queue when he was killed are lost. The best way to solve this problem is to add another loop of thread; After your existing while the loop closes, loop with a short (10 msec) delay until the queue is empty (by Get Queue Status). Kill the queue only after all your results have been written to disk.

• Failed to load the message when the wifi or data are disabled...

  I get the message "could not load. Please check your internet connection and try again ' when I unlock the screen or disconnect the wifi connection or data.  I am not in a position to say what app it is, how can he know whether the app is the cause?

  The message now seems to have disappeared when I uninstalled a few 3rd party applications.  My guess is it could be one of them or a recent update of a few apps.  I however, in the future, will be the option of restarting mode safe in mind if it happens again.  Thank you for your help.

  Hi Sumitava_Datta,

  Please report this issue in jira (developer Issue Tracker).

  I confirm this Zmey solution work. I tried it myself and it indeed gives a solution to this bug. Just use isEmpty() instead of isNull(), who is not recognized as a valid QVariantList function.

  QVariant list = xda.load(
  QDir::currentPath() + "/app/native/assets/contacts.xml",
  "/contacts/contact");
  
  QVariantList l = list.value();
  if (l.isEmpty())
    model->insert(list.value());
  else
    model->insertList(list.value());
  

• Keep the original creation date when copying or moving files (Windows XP/7, Windows Server 2003/2008)

  I know that the default behavior of (any version) Windows when copying or moving files, is that Windows makes everything first creates a new folder, copy the content, and when you move files, deletes the source after successful copy folder. Unlike Mac OS, where mechanisms of copy and move assume that when you copy a folder, the properties of the copied folder should have the same properties as the source folder, so to keep the original date of creation!

  Is it possible to change this behavior in Windows? I know that Robocopy in Windows Server 2008 has an option to keep the dates of creation of record, but I would like to know if you can change Windows 7/Windows Server 2008 behave similarly.

  It is very annoying that when you restore or copy a folder, the new folder has the date of the creation of the current date instead of the date of original creation.  People tend to look for old records that exist is no longer when you copied or moved the files.

  Hey E Kyung,
   
  There is no way to do this in windows. The design of Windows, this is the creation date refers to the file, while the date of the amendment relates to the content. If the creation date is really important to you, you can set after the copy with a utility.

  The easiest is to right-click on the file and drag it to the destination folder. you will be asked to copy or move. If you move, the creation date will not change.

  Yes, Robocopy is available in Windows 7.

• The loss of data on migration of Tungsten T Centro

  When you do the initial hotsync of my Centro, I seem to have lost all my 5 appointments and contact information. When I look at the Hotsync log I see no reference to one of these programs. I made my date and contact information work with Palm Desktop, list of contacts from the Agenda 5 and office. What I see in the paper is the reference for Outlook similar for these programs.

  Not on my desktop, Palm Desktop is empty dates and contacts, my Centro is empty dates and contacts, but all the information survives on my Tungsten and only my Tunsten I can say. I don't see that there is a Palm backup directory that has a folder named Agenda 5, but I don't know how to see if it's my data of tungsten or centro.

  How can I get all my data on my Centro tungsten so that I can continue to serve my appointments and Palm Desktop Organizer programs?

  Thank you

  Doc

  This Palm knowledge base article discusses switch between Outlook and Palm Desktop.  I've never used Outlook to synchronize with, so I can't be of any more specific than that... except maybe help to uninstall and reinstall the software if you can not pass as discussed below:

• How to avoid the screen for authentication when you call a process?

  Hello!

  I created a simple Web service in Workbench to generate a sequential ID to PDF Forms.

  It is working very well, but the shape is open a Windows application login and password security dialog box to access the Web service.

  
  There are over sixty of these forms to be used by some 4,000 employees, it will be a major problem.

  
  Question: is there a way to use the process and sending authentication information when the form is opened and avoid this dialog box entirely?

  
  Thanks a lot for the tips!
  

  Marcos

  You can disable the authentication of the web service so that the user will not be asked to enter their credentials.

  This can be done through /AdminUI-> Application & Services-> service management-> your WebService-> Security-> appellant require to authenticate = no

• Specify the type of data when using the "CREATE TABLE AS SELECT"?

  In the table creation code I'm trying to create a DATE column called DOB below. However, the resulting DOB column in the condamnes2 table is a Varchar2. How can I specify that I want to be a DATE field DOB? (I know that I can create the structure first and then fill it but this isn't what I want.)
  
  create the table condamnes2

  Thank you

  Use the CAST function in your decoding:

• Loss of data when resizing table 2D

  I data collection and insert in a table I did great I know will be used.  I then resize the table using SetArrayBounds, because I now know the number of iterations that have been executed.  I find myself with an array of correct size, but the data consist of the first line with only the first column is missing.  All other elements are 0 (matrix of numbers).  Any idea what's going on?

  I wanted to start with an empty array, resize to any line and the number of columns before you start the iterations, then add a line at the beginning of each iteration.  I was shot on this, but it seems that it works better.

  Kelly Bersch

  Hi Kelly,

  Could you show us the code you used to implement? Specifically, the resizing of the table? http://forums.NI.com/T5/NI-TestStand/what-is-the-syntax-for-SetArrayBounds-for-a-multi-dimensional/t... This thread shows the correct syntax for the command and its implementation.

  If I understand correctly that you slowly fill this table which has been initialized to 100 x 100. The first thing we should do is to initialize the array to 100xthe number of columns if at least we can stop worrying about the columns since you already know how many settings you are testing. Then at the end of the sequence, you can resize the lines using the above command.

I found a reference to a session of world BlackBerry - Introduction to the Native API of camera C / DEV179 I would really appreciate a recording or a slide deck or something of this presentation, but if this is not available, can someone tell me the * general * sketch for the camera work?

  The ipd file can only be used with the Office Manager. Open the Desktop Manager and go to the backup and restore > restore

  Navigate to the ipd file and go through the steps. It should restore all the information stored on your phone.
