• Write to binary files

  I want to save data in a binary file. This VI takes into account several channels and displays them in a bar chart. The generated waveform out with precision, but the generated text file does not save the data. It's only a few characters long, and I don't seem to be able to interpret it at all. I tried to save the data of type variant and the data after the conversion (before it is in graphic form). The files and the VI are attached below. Any advice on where I'm wrong would be greatly appreciated.

  

  Shultz,

  Do you intend to write a binary file (more effective, unreadable by humans) or (less effective, human-readable) text file?  They are of two different file types.

  The code in your screenshot opens a text file but then saves the binary data of the Variant.  These data are likely not as ASCII (text) format so when you try to play you see what appears to be garbage (really, what happens is that your text editor's interpretation of the 1 and 0 of binary data of type variant as ASCII coding).

  If the chart appears correctly, then I think that the GetData UMCBICONN2 returns an array of numbers.  In this case, you want to convert this table of numbers to strings, and then use writing text VI of file to save to disk as follows:

  

  Sorry for the screenshot - I would normally post an excerpt or at least fix the VI but I work on a development machine that does not have a version of LabVIEW on it and you don't would not be able to open any VI I saved.

  I hope this helps. Best regards, Simon

  Deleted file recovery can recover incomplete files, i.e. the part of these files may be missing.  Recover deleted files is much more reliable if recovery of a backup, instead of using recovery software.

  These things depend on the operating system and the file system.

  One thing, you can see: open one of these files damaged with a text editor, and then make sure that the constant % PDF is somewhere in the first 1024 bytes.

• No mails a file with header showing the number of unread emails!

  My Mozilla Thunderbird works very well for several of my Gmail, Hotmail and Yahoo email accounts. However, for one of my Yahoo accounts, I have several records that show the number of unread in this folder but no mail mails that can be downloaded or shown on this particular issue. This problem exists in some of my personal files and the folder of mail "sent" as well. I checked the article on the disappearance of mail (http://kb.mozillazine.org/Disappearing_mail) but nothing there helps.

  Can someone help?

  Thank you very much!!!

• Properties tab shows 3609 files, when you select all the files it only shows the files in 1974?

  When I right click and select Properties tab it shows 3609 files, when selecting all the files to copy shows only the files of 1974?

  Hello Tony,.

  If it is certainly a big difference, I think that for most all of this is taken up by folders and subfolders which are mainly empty place holders. Have you looked at the folder with Windows Explorer? A freeware application that can help is WizTree, it provides both a performance graphics and text of what's on your hard drive (or part of it). Can be very educational. Download here: http://antibody-software.com/web/software/software/wiztree-finds-the-files-and-folders-using-the-most-disk-space-on-your-hard-drive/ .

• After you rename the computer, the backup of the file history still showing the old name of the computer to its destination.

  Original title: history of Falie Worng Destination path

  I changed my computer name [my computer setting and the name, display name, computer and computer Description all equal under the same name]. But when the history of files backing up my files, he insists on putting the OLD computer name in the backup destination path, for example:

  Backup_Drive\\Backup_Folder_A\UserID\Old_Computer_Name\Data...

  I tried selecting a new backup drive and reboot several times, but the history of files always comes back to the old name of the computer when you create the destination path.

  How can I fix?

  Similar to the response of Siva here, you will want to return to

  C:\Users\\AppData\Local\Microsoft\Windows\FileHistory

  Now, if FileHistory was lit before, using the old username, there will be a configuration file and the Config1.xml and Config2.xml files will contain several tags using the old name of PC. Rather than wipe these files, open each file in Notepad and search for the name of your old PC and replace with the name of the new, do not forget to save.

  In addition, if you want to keep a backup that has already been created with the old name of PC, you'll need to find, rename the main folder ("old name PC") and in this folder, rename tags in the Web configuration files (as you did in the local configuration files).

  When I tried to delete my local config files, he would recreate using files of configuration of the backup, that were also incorrect, so I just manually renamed and mine works fine now under the new name of PC.

• How to ensure that the binary file is stored in the location specified for my DLL files?

  I'm new to computers and has a Dell Inspiron 1545 laptop with a program in Windows Vista Home Premium on a 64-bit platform. I have a thread in my sidebar gadget new MSNBC and the dates for the stories are frozen in December of last year and does not update the current stories. I had no problem with this before and I haven't added or deleted programs because of this problem to the best of my knowledge. I got advice here on the checking of dll files and 4 of them come back with saying error messages and see that the binary is stored at the specified location for debug files. I searched for information help with this and I found a few tips that not saved and re-entered the files, I tried and different versions of the idea, at first it made no difference and then I redid it and it screwed up my weather gadgets so I redid it and they worked very well. I then tried on the DLLs for the MSNBC gadget, but it doesn't seem to change anything, although the gadget to power for the Dow Jones News feed is now screwed up. Is there a site I can go to what can explain the route of binary/specified path or debug file. Save/re seems to be the right path, it affects obviously the gadgets but not as I want, any help in this direction would be appreciated at. Meanwhile I'll go back and try again.

  Hi dumdeedumdum

  
  What are the files dll are facing problems with?

   

  You can perform a SFC scan and check if the problem is resolved.
  To Perform a Scan SFC -
  a. click Start, click programs, on Accessoriesprincipally made, right click guestand then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on Allow.
  b. type the following command and press ENTER:
  sfc/scannow
  A message appears indicating that "the system scan will start. Be patient because the scan can take some time.
  c. If all files require a SFC replace will replace them. You may be asked to insert your Win7 DVD for this process to continue.
  d. If everything is correct you should, after the scan, see the following message "resource protection Windows not found any breach of integrity".
  e. once the scan is finished, close the command prompt window, restart the computer and check.

• Write an xml file - how to value the question

  I'm writing an XML as follows:
  <? XML version = "1.0" encoding = "utf-8"? >... < attribute tag = VR "00080008" = "CS" > ORIGINAL\PRIMARY\WHOLE BODY\EMISSION < / attribute > < tag attribute "00080012" VR = "DA" = > 20100302 < / attribute >...
  I have no problem affecting the Tag = "00080008" and VR = "CS". What makes me mad is how to define the string ORIGINAL\PRIMARY...
  
  What I get is:
  < attribute tag = VR "00080018" = "User Interface" / > with no inserted string. (Ignore the fact that the tags are different, will make any tag). I would like the string, then the closing < / attribute >. Mine closes immediately.
  The code is:
  Attrib element;
  ....
  attrib = doc.createElement ("Attribute");
  tmp = makeHex4(grpEl[0]) + makeHex4(grpEl[1]);
  attrib.setAttribute ("Tag", tmp);
  attrib.setAttribute ("RV", varType);
  attrib.setNodeValue (metaVal);
  instance.appendChild (attrib);
  
  I thought that the attrib.setNodeValue (metaVal) would do the trick, but it doesn't. I have also thought about using attrib.appendChild (metaVal), but that does not make sense since I should add a node, not a string.
  
  Since I was the example file, I know that we can somehow, but I don't know how to do it. I would appreciate a suggestion from someone who knows more about the topic I am doing.
  
  Thank you
  Ilan

  Monitor all that supports the dom will return with this, assuming metaVal is the content string (with the backslash escaped well, say, if applicable).

  attrib.appendChild(doc.createTextNode(metaVal));
  

  If she supports (at least partially) dom level 3, it probably supports this as well.

  attrib.setTextContent(metaVal);
  

• The binary file format

  With the help of LV2010.  I have a program that stores data in a binary file.  The file is a set of strings and floating point values.  I need to write another program in VB.NET that can save/read these files, so I need information on the actual file format of the data.  Is there a documentation which describes how the file is saved?  Thank you.

  Interesting. Usually, this question gets asked in the opposite direction with people trying to decode in a cluster.

  If you use the WriteToBinary function, your data are written as native data types in order to cluster in the binary file. Because you use a cluster, each string is being preceded by a length, which I believe is an I32.

  This is described in the help file for writing to a binary file. I think the people of thing travel length of string/array much however.

• Adds data to the binary file as concatenated array

  Hello

  I have a problem that can has been discussed several times, but I don't have a clear answer.

  Normally I have devices that produce 2D image tables. I have send them to collection of loop with a queue and then index in the form of a 3D Board and in the end save the binary file.

  It works very well. But I'm starting to struggle with problems of memory, when the number of these images exceeds more than that. 2000.

  So I try to enjoy the fast SSD drive and record images in bulk (eg. 300) in binary file.

  In the diagram attached, where I am simulating the camera with some files before reading. The program works well, but when I try to open the new file in the secondary schema, I see only the first 300 images (in this case).

  I read on the forum, I have to adjust the number of like -1 in reading binary file and then I can read data from the cluster of tables. It is not very good for me, because I need to work with the data with Matlab and I would like to have the same format as before (for example table 3D - 320 x 240 x 4000). Is it possible to add 3D table to the existing as concatenated file?

  I hope it makes sense :-)

  Thank you

  • Good to simulate the creation of the Image using a table of random numbers 2D!  Always good to model the real problem (e/s files) without "complicating details" (manipulation of the camera).
  • Good use of the producer/consumer in LT_Save.  Do you know the sentinels?  You only need a single queue, the queue of data, sending to a table of data for the consumer.  When the producer quits (because the stop button is pushed), it places an empty array (you can just right click on the entry for the item and choose "Create Constant").  In the consumer, when you dequeue, test to see if you have an empty array.  If you do, stop the loop of consumption and the output queue (since you know that the producer has already stopped and you have stopped, too).
  • I'm not sure what you're trying to do in the File_Read_3D routine, but I'll tell you 'it's fake  So, let's analyze the situation.  Somehow, your two routines form a producer/consumer 'pair' - LT_Save 'product' a file of tables 3D (for most of 300 pages, unless it's the grand finale of data) and file_read_3D "consume" them and "do something", still somewhat ill-defined.  Yes you pourrait (and perhaps should) merge these two routines in a unique "Simulator".  Here's what I mean:

  

  This is taken directly from your code.  I replaced the button 'stop' queue with code of Sentinel (which I won't), and added a ' tail ', Sim file, to simulate writing these data in a file (it also use a sentinel).

  Your existing code of producer puts unique 2D arrays in the queue of data.  This routine their fate and "builds" up to 300 of them at a time before 'doing something with them', in your code, writing to a file, here, this simulation by writing to a queue of 3D Sim file.  Let's look at the first 'easy' case, where we get all of the 300 items.  The loop For ends, turning a 3D Board composed of 300 paintings 2D, we simply enqueue in our Sim file, our simulated.  You may notice that there is an empty array? function (which, in this case, is never true, always False) whose value is reversed (to be always true) and connected to a conditional indexation Tunnel Terminal.  The reason for this strange logic will become clear in the next paragraph.

  Now consider what happens when you press the button stop then your left (not shown) producer.  As we use sentries, he places an empty 2D array.  Well, we dequeue it and detect it with the 'Empty table?' feature, which allows us to do three things: stop at the beginning of the loop, stop adding the empty table at the exit Tunnel of indexing using the conditional Terminal (empty array = True, Negate changes to False, then the empty table is not added to the range) , and it also cause all loop to exit.  What happens when get out us the whole loop?  Well, we're done with the queue of data, to set free us.  We know also that we queued last 'good' data in the queue of the Sim queue, so create us a Sentinel (empty 3D table) and queue for the file to-be-developed Sim consumer loop.

  Now, here is where you come from it.  Write this final consumer loop.  Should be pretty simple - you Dequeue, and if you don't have a table empty 3D, you do the following:

  • Your table consists of Images 2D N (up to 300).  In a single loop, extract you each image and do what you want to do with it (view, save to file, etc.).  Note that if you write a sub - VI, called "process an Image" which takes a 2D array and done something with it, you will be "declutter" your code by "in order to hide the details.
  • If you don't have you had an empty array, you simply exit the while loop and release the queue of the Sim file.

  OK, now translate this file.  You're offshore for a good start by writing your file with the size of the table headers, which means that if you read a file into a 3D chart, you will have a 3D Board (as you did in the consumer of the Sim file) and can perform the same treatment as above.  All you have to worry is the Sentinel - how do you know when you have reached the end of the file?  I'm sure you can understand this, if you do not already know...

  Bob Schor

  PS - you should know that the code snippet I posted is not 'properly' born both everything.  I pasted in fact about 6 versions here, as I continued to find errors that I wrote the description of yourself (like forgetting the function 'No' in the conditional terminal).  This illustrates the virtue of written Documentation-"slow you down", did you examine your code, and say you "Oops, I forgot to...» »

• Problem with writing in the new file every day, error #1

  Hi, I have build a vi that writes data measured for each second of the file. This vi will be used for the acquisition of long-term data and I want to write the data to a separate file every day, else the file becomes

  very large. The vi is supposed to work like this, first set the folder to save it and then start logging with the "datalogon" button, first write the column names in the file and after that write data

  every second. If the date is the same newspaper, data, if the date is not the same write the new file name, write the column headers and write the data again every second. The date is used as the file name.

  This work is quite good only at the beginning of the vi I get the message "error 1 occurred open/create/replace the file writable spreadsheet String.vi-> write to the spreadsheet (string) .vi-> NHR file -

  SerialDaq - 03 APR 2013 .vi. I did some tests and it seems that in the first or the second round of the loop, the path in the annex is ' file name:------"and not drive:- and this seems to be caused by the fact

  that I first write the column headers, and then the data (if I write only the data of the problem does not occur).

  So I (think) for what is now the problems but don't don't know how solve it, I would appreciate it if someone could help me with this.

  Regards, Martin

  I made the change you mentioned and to my surprise I got the error message and also, with the vi you sent, I took look at it and found that:

  -If I first enter the "folder to save the file', then run the vi and then press on the" data connect "I don't get the error.

  -If I first run the vi, then enter the folder ' save file to "and the hit" the data log on ' I get the error.

  I also tried with the vi original (without the connection shiftregister in the case of false and init for removal) and which gives the same result as above. If I get the

  error message and choose stop the vi, start the vi again once I don't get the error because the folder in which the file is entered. This issue appears only when there is no file «»

  to save the file "in the dialog box.

  While I'm writing this I realize that "folder to save the file" is outside the while loop so only executed at the start of the vi is maybe I have to put it inside the while loop? A tried

  This and at first, it seems that the problem is solved, I don't get the error message on my screen, but it still appears on the error handler in another part of the vi (visa series).

  Oh, Yes. The 'name of the resource visa' and 'file to save the file' are both outside a while loop and are only read at the start of the vi, at the moment they have not a valid

  the error value is generated.

  Problem solved, thank you for your comments!
