Binary file is greyed out in Write Measurement File express VI.

I am running labview 8.2 on Fedora 7 Core. I have also installed it on an earlier version of fedora that was in line with the supported red hat distribution. The problem is that when I try to use the Write Measurement File express VI, the binary file option becomes greyed out after the dialog box opens up. It is present for a second but it is impossible to select. When I have tried bringing over a vi written in Windows (where the binary option was available), the option is also disabled. I am trying to avoid writing the file out in lower level code since I want to use the auto file name generation available under the express VI. If any body knows a workaround or has some sample code that writes out a new file for each measurement with the date and time in the filename let me know.
Thanks

Hi Ikiller,
Is this still occurring?
Could you please provide a screen shot to show the behavior?
Thanks!!

I write binary file (express) but can't read it (express)

Hello,
I have an application where I will acquire data from several sensors. For most of them (16) a relatively low sampling rate (10000Hz) will be fine, but, for one AE sensor I need a high sampling rate (50k - 100kHz). So, I've decided to store the data in binary format so as no to have way too big files.
I try writing the files with the express module, and afterwards, in a new .vi, reading and graphing it to check it, but signals don't match.
By now I'm working with simulated channels, so data stored in the file and read and graphed afterwards should be sine, but I don't see so.
Any suggestions?

Hello,
I have tried my best cleaning up the wiring, but it's still pretty messy. I attach the complete program.
My problem (still not solved) is that since EA needs to be measured at very high rate, I want to write it as binary data. But I cannot make it show me the correct data afterwards, with a different program, that doesn't matter.
I would also like to know how to convert this saved data to MatLab... any suggestions? (should I post this in a new thread?)
Regards,
Usuario

Problem when streaming out a binary file

Hi,
I am trying to stream out a binary file to an output stream (not a file, but a socket). My file is a gzip file, and I was initially simply trying to open the
file, read it to a a byte array, and writing it out to my output stream. However, I got corrupted data at my other end and it took me quite a bit of
debugging hours to find out why.
I tried writing to a file the same information I was writing to my output stream but, although my file was correct, my output stream still contained
corrupted data.
I think I have finally narrowed down my problem to the fact that when I try to write a 0x00 value to my output stream, everything gets ignored from this
point until I write a 0x0a byte to my output stream. Obviously this produces corrupted data, since I need all the bytes of my binary file.
If somebody can direct me as to how to write a 0x00 value to a socket output stream, I would really appreciate your input.
This is a sample of my code (Right now I am writing byte by byte: not very efficient, but was the only way I found where I was getting a problem):
// out is of type OutputStream
if (Zipped){
     // In this case we just have to stream the file out
File myFile = new File(fileName);
     FileInputStream inputFile = new FileInputStream(myFile);
     FileOutputStream fos = new FileOutputStream(new File("/tmp/zip.gz")); //zip.gz results in a good (not corrupted) file.
     ByteArrayOutputStream out1 = new ByteArrayOutputStream(1024);
     int bytes = (int)myFile.length();
     byte[] buffer = new byte[bytes];
     bytes = inputFile.read(buffer);
     while (bytes != -1) {
          out1.write(buffer,0,bytes);
          bytes = inputFile.read(buffer);
     inputFile.close();
     try {
          int count=0;
          bytes=out1.size();
          while (count<bytes){
               fos.write(buffer,count,1);
out.write(buffer,count,1); // when buffer[count] == 0x00, everything after it gets ignored until a 0x0a byte is written.
               count++;
     } catch (IOException ioe) {
          SysLog.event("IOEXCEPTION: "+ioe);
     } catch (Exception e) {
          SysLog.event("EXCEPTION: "+e);
     fos.flush();
     fos.close();
     out.flush();
out.close();
     return;
}

Actually, I had thought about that and for some time I tried getting rid of some of the header information in the gzipped file, and then I stopped doing that when I realized that part of the gzipped file is a CRC value which I believe is computed taking into account both the data of the file and the header information. If this is the case, then getting rid of part of the header would produce a corrupted file ... but then, I might be wrong in this issue.
Anyway, to make my application more clear, what I am doing is writing the code for a cgi command which is suppossed to access information from a database, create an xml file, gzip it, and then send it to the client who requested the information.
Therefore, what I am sending is an xml file (Content-Type: text/xml) in compressed format (Content-Encoding: gzip). Note that if I don't gzip the file and then send it uncompressed to the client, I have no problems. However, for me it is very important to gzip it because the size of the file can get very large and that would just take bandwidth unnecessarily.
On the other hand, if I try to gunzip the file locally, I have no problem either (the file is not corrupt at the server's end). Therefore, my problem is when I stream it out.
Any further help would be really appreciated!

Write structure to binary file and append

I have a very simple problem that I cannot seem to figure out, which I guess doesn't make it so simple, for me at least. I've made a little example .vi which basically breaks down what I want to to. I have a structure, in this instance 34 bytes of various data types. I would like to iteratively write this structure to a binary file as the data in the ACTUAL structure in my .vi will be changing through time. I'm having trouble getting the data to be appended to the binary file rather than overwriting it since the file size is always 34 bytes regardless of how many times I run the .vi or run the for loop.
I'm not an expert, but it seems if I write a 34 byte structure to a file 10 times, the final product should be a binary file of 340 bytes (assuming I haven't padded or prepended with size).
One really strange thing is that I keep getting error #1544 when I wire the refnum out wire to the file dialog input on the write function, but it works fine when I wire the file path directly to the write function.
Can someone please swoop in and save me from this remedial task?
Thanks for all the help. NI Forum rules!

Did you consider reading the text of the error message? Don't set the "disable buffering" input to true - just leave that input unwired. Why do you want to disable buffering?
As a general practice, the file refnum should be stored in a shift register around the for loop instead of using loop tunnels, that way if you have zero iterations you will still get the file refnum passed through correctly. Also, there is no need for Set File Position inside the loop, since the file location is always the end of the last write unless it's specifically moved to another location. You might want it once outside the loop after you open the file, if you're appending to an existing file.

Write to binary file different from 8.0 to 8.2?

I am communicating with a device via USB and am using a method setup by the USB driver programmer. To communicate, I write to a binary file with a filename of \\?\COMx. This has been working fine for about a year in mfg with Labview 8.0. I recently "upgraded" to 8.2 and now it does not work. If I save for a previous version and run 8.0 it works fine. How can I make this work with 8.2?

Yi Y,
The USB device is one of the instruments we manufacture. The USB driver is written so writing to the USB port is just like writing to a file. I use the binary read/write VI's to send and receive commands to this USB device. The filename I use is \\?\COM#. I am told by the USB driver creator that this is common for low level C. I have been using this VI for that last year and recently upgraged from 8.0 to 8.2 and it does not work. I run the same vi under 8.0 and it works fine. This is not a common way to communicate, so will probably not get an answer.
My next question is, is there any way to run an 8.0 dll or vi from an 8.2 executable?
Thanks
Hi dgtest1,
Which USB device you are using, and which driver are you using? I'm trying to figure out specifically how you are communicating with the USB device by writing a binary file and how was the binary file written. Could you please post more information to describe in more details about what your set up is doing?
Thanks!

Write to binary file

I have a relatively large 3D array (Phase Settling), which I want to store in a Binary File. The array is a 15000 point sweep (after decimation), repeated up to 48 by 48 times (in two FOR loops, one inside the other), meaning it can end up having as many as 34,560,000 data points. At the moment, I am attempting to dump that 3D array into a Binary File in one go, using the following VI. There are two possile versions of this array (both the same size as each other) and, depending on which has just been tested, they will be written to their own individual file. Once both tests have been run and their results stored, the idea was to open both files, subtract one array from the other, and store the new 3D array to another Binary File whilst also displaying this latest data elsewhere in a higher-level VI.
After its first trial run, LabVIEW presents me with an error message saying something along the lines of "LabVIEW had run out of memory". I assume it would be to do with this VI, since that's where the first error code appeared (Error Code: 2), apparently originating in a 'Write to Binary File' function.
Any ideas as to how I could get round this first hurdle, or perhaps an alternative method I could try?
Thank you.

Running out of LabVIEW memory when writing to binary file.PNG ‏30 KB

Well, as shown in the attached screen-shot, the error indicator shows an error code of 2, and that the error occurred in one of the Write to Binary File functions.
However, when trying to save this particular VI after a couple of tweaks, I was presented with the following pop-up alert message:
LabVIEW: Memory is full.
Cannot save VI "Compare Amp - calculate.vi".
LabVIEW Save error code 10: Default data space.
Anyway, returning back to the main problem at hand, I've though of a couple of possible solutions...
We don't really need a particularly high resolution to the data points for the comparison, so I could convert the array doubles into an array of singles to save space.
I should be able to implement the 'Write to Binary File' for the initial arrays into the outer FOR loop, thereby reducing the amount data written in each instance by a factor of up to 48. The only problem I can foresee in this is that I'm not sure how to append 2D arrays into a binary file such that, when the file is read, they would appear as (or be easily converted into) a 3D array.
As for the 'True' case in my case structure, am I being grossly inefficient in my passing of data from one place to the next? I know there are a lot of branches (and buffers?) of 3D arrays; is there a decent way to reduce this overhead by tweaking the data paths or something?

Write to Binary File strips carriage returns (LV 8.2.1)

   I was using Write to Binary File to write a combination of strings, numbers, and time stamps. When I later went to read the filel, it didn't quite make sense. Although I had written strings that had lines ending in <CR><LF>, when I read them back in, they only had <LF>. I checked this using other programs to read the file. The <CR>'s have been stripped out! Why would a "binary" file VI kindly edit your strings for you? I needed the strings to be written exactly as they were. The VI corrupted my data.
   I couldn't find any explanation for this in the help, nor any way to turn this behavior off. Is this a known issue, a bug, or a feature?

   Thanks, Altenbach and Jarrod, for your help.
   Time to eat crow. At Altenbach's prompting, I created a sample program that would demonstrate the problem. It didn't. Turns out the files were fine. I was reading them with the "Read from Text File" vi, with the EOL option enabled! I had used another program to check the data in the file, and was basing my conclusion on that. Unfortunately, I didn't use a good hex editor, and it turns out the program I used was also stripping the <CR> off. So the data in the file was good, I was reading it wrong, and my double-check was reading it wrong.
Cheers,

Write output to binary file in C/C++?

How can I write output to a file in binary format instead of ascii?
Or... if I am using a buffer.. to write a buffer to binary format instead of ascii?
I am writing a lot of data to a text file and I would like to reduce the size by writing it all into a binary file instead of ascii?
Last edited by kdar (2012-12-13 14:36:41)

Basic I/O?
char buffer[100];
// C++ style
ofstream file;
file.open ("data.bin", ios::out | ios::binary);
file.write(buffer, sizeof buffer);
/* C style */
FILE* file2 = fopen("data2.bin", "wb");
fwrite(buffer, sizeof buffer, 1, file2);
A lot of people prefer the old C style functions for binary i/o even in C++ (and iostream for formatted i/o). Writing and readong more complex structures requires some castin, in C++ usually done with reinterpret_cast<char*>(someStructure).

User read & write permissions greyed out in sharing

Hi I am trying to access a Fat32 formatted HD plugged into a Macbook running lion from a Macbook Pro running Mavericks. When i go into system preferences and sharing I am able to see the External HD and share it but the read and write options for the users are all greyed out. Also when I access the macbook through sharing or connect to server I am unable to see the external HD but I do see the other shared folders on the macbook's internal drive. I have tried to verify and repair the drive but it has not solved the problem. Any suggestions would be greatly appreciated.

In system preferences on both macbook's , you need to go to file sharing and making sure it's on for both ,click on options and enable smb for windows. follow instructions. I am assuming that the external drive has windows formate on it.

Multiple writes of a DBL 2D array to binary file

Hello.
Does anyone have an example of writing a 2D array to a binary file multiple times?
Specifically, I need to write a 2D array of DBL to a binary file mulitple times and then (later) be able to read it back (reconvert to DBL). All of the examples that I've found only do one write and then close the file. I need to leave the file reference open and write data to it over the period of a few days. The data comes out of a queue that is fed from a DAQ loop. (In an acquistion loop I feed a queue and in a slower loop I dequeue the data and write it to disk)
I believe it has something to do with the pos mode and offset mode but I can't figure it.
I haven't been able to successfully read the data back yet from the .bin file so I'm not sure if I'm even writing it correctly.
The closest example that I've found is the High Speed Data Logger and High Speed Data Reader but I haven't had any luck with those.
Thanks in advance.

Go to Solution.

To change the representation of a number, use the Numeric > Conversion sub-palette.
The example below shows that the wires contain the representation info independently of the destination indicators : you can connect different types of numerics to the same wire and LabVIEW will automatically adapt to the type (the coercion dots indicate that a convertion has been done). Everything you should want to know about converting numbers is explained in the LabVIEW Help : "Conversion VIs and Functions"

IWork Files Greyed Out

Hi
I bought an iMac G5 second hand. It had old, licensed copies of iWork on it. I deleted them and installed my licensed copy of iWork. The Mac seems to have picked up the previous users license key but I am able to create and save documents in Keynote etc.
However, when I try and email using a webmail client, any iWork files are greyed out and not selectable. Other files created in, say, Text Edit are selectable as attachments.
I have trashed the plist file for Keynote but this does not help. Permissions for the file are read and write. I am signed in as an Administrator.
Does anyone have any ideas about how to fix this?
Thanks
David

Control-click a document, compress or archive it, and attach the zip file. iWork creates packages, which look like files but are actually folders, and these cannot be directly attached to an email.

How to write a 2-D Array of Doubles to a binary file in LabView 8.5?

Okay, this is driving me nuts. I got a program that worked fine in LabView 8.0 but refused to write any data after my institute upgraded to LabView 8.5. The data is stored in a 2-D array of doubles and is supposed to be written to a binary file, that has been correctly opened and got a header written to it containing some meta-data of the measurement. But when the doubles from the array should be written to the file, nothing happens. All I get is an (except for the header) empty file of 786 kB. I found out that writing works if I convert the data from the array to singles right before wiring them to the "write to binary file" VI, but for several reasons I need the data as doubles. Can anyone help me? I've tried everything anyone has written here about writing to binary files and more.
Remember, it worked perfectly fine with an older version of LabView. Any ideas?

It is possible that you run into a known memory optimization bug.
Try to place an "always copy" primitive as discussed here.

Greyed-out file icon in Pages on iPhone 4

I somehow ended up with a greyed-out file icon (Pages) on my iPhone 4 after uploading it to the cloud from my Mac. It won't delete and is not recognized as even existing when I attempt to write over it. Any ideas how I might be able to delete it? It's showing a progress bar, but no "progress" is occuring. I've tried everything short of resetting my phone (turned phone off and back on, deleted Pages and reloaded it, turned iCloud off and back on, etc.

Problem went away on its own, I think after I moved some files from my desktop to the Trash and deleted them from my computer.
