Error file open/create/replace FPGA

• In the file open/create/replace bug

  I found this problem in LabVIEW 2009. The Boolean indicator doesn't seem to work properly in the first snippet. It returns TRUE even with a valid path. With some trial and error, I found a work around that will work correctly at the moment. I just wire an Out error after the file open/create/replace (excerpt of a second). Is this a bug? I'm doing something wrong?

  I had a lot of code that uses it to test to search for existing files, and then the output of wire to a statement box. I know there's also a check if the folder/file available Exists.vi. I wouldn't spend a lot of time to change all my code if there is a known bug and it will be corrected in the next update. If this isn't a bug to know, where can I submit it?

  

  

  This isn't a bug. You have the race condition between the indicator and close REF.

  Use it in this way:

• Strange behavior file open/create/replace

  Hi all

  I will make my question as broad as possible because I think someone must have met this behavior before. I use the function open/create/replace file to programmatically open a file, giving a path entry created in an earlier vi. Strange behavior, I see, is that although Labview returns 1 error when I give my file programmatically, it reads the file OK if I give as a constant. The constant path that I give is exactly the same as one I am tryinng to programmatically.

  Any suggestions? Is it to do with a string formatting problem? I enclose my portion of treated VI the path_in section.

  Thanks for your time,

  Kind regards

  Harry

  Wild guess: you must use 'build path' instead of 'concatenate strings' build path.

  (Also use a constant of diagram of the path (not a string!) to "c:\ni-rt\" and get rid of the "trim whitespace' and the 'chain of path")

  See if that makes a difference. (build path is OS independent, while the operations of independent channels are not).

  Never use the paths as strings. There are very few cases where this would be appropriate.

• Error 7 open/create/replace the file to write spreadsheet String.vi

  Hello

  I try to use a CompactRIO with 9225 analog input module for measuring an analog signal.

  Version of LabVIEW is 2013 (32 bit), when I run only e VI, errot 7 has taken place.

  I'm sure that the path is correct, but the error information indicate used different path "------" is not "/", I have attached the picture.

  I don't know why this is happening, appreciate any suggestion to solve this problem.

  Thank you.

  The cRIO-9075 doesn't have the ability to mount a Windows network share and the read/write directly with the host computer.  You'd have to do, this is the file from the FTP host (the host has to a customer, and the RT system has a server) or to run an FTP server on the host that the target can interact with (the host would then have a server, and the target's screws of the FTP client) to get the file to the location.

• 6 open/create/replace the file in NI_Excel.lvclass:Save report error to

  I have an application that works on LV60 and when lance in LV86 I get the following error: error 6 took place in open/create/replace file in NI_Excel.lvclassave report to the File.vi-> SWF001 Test.vi Possible reason (s): LabVIEW: file generic i/o error. = OR-488: IO operation abandoned.

I use it with Excel 2003 SP3 and the spreadsheet contains macros (and I get a prompt ' should I enable macros: "(Yes), I do not have with LV60 and the old version of Excel). This is probably not the problem? but deserves to be mentioned. The file exists on the system (and it seems that the application is to write on it with success - but maybe truncated as the error indicates-i cannot say with certainty). I can open and save the Excel file independently LV very well. Clues? Thank you very much! -David

  
  

• Can not read the text file: 7 error file not found

  Hello

  I read a (header.txt) text file that is placed in the same directory as the vi. I use winXP & Labview 8.6. The VI reported an error:

  Error 7 open/create/replace the file in OpenTextFile.vi.

  However, I copied the path of the file at the end of the error message and pasted into the address bar of IE, and I found that IE can open the file.

  Why does this work?

  Thank you

  Ryan

  Never mind. I solved it. I fed the wrong file name in the diagram.

• Open/create and write to multiple files

  I'm doing data acquisition high speed and save data in the file.  I will acquire a large amount of data, so save in one file would result in my file to jump in size.  This is why I would like to save my data in several files.  I'm trying to figure out how to open several files, then choose which of the file to write to.  My approach is to open/create multiple files and save their refnum into an array.  Then I would choose what file to write from this array.  I enclose my VI, everything I have so far.  It seems to me to get errors, the "Double-track" or "input parameter is not valid. For example if the input is a path, the path can contain a character not allowed by the operating system such as? or @. "How could start with this problem?

  Figured it out...

• error 42 when creating a zip file

  Hello

  I get a 42 error when I try to create a zip file in Labview.  I am deploying to a PSC module.  I try to create the file, and then my loop will close a data file when it gets to 1 meg and add it to the .zip file open and open another file of data.

  I can't test the part until I can open a zipfile first.  Seems that I do not know how to specify a path? My way, that I use for the data file is "c:\k2XXXX.dat" with XXXX being the graduations to current.  And the zip that I use is "c:\K2data.zi" why does this job with creating zip file VI?  I use the vi path string.

  Thank you

  Hello Zener,

  Please contact National Instruments!  I've seen this error before when using the ZIP screws on a controller of the PSC.  Unfortunately, this error occurs because the ZIP screws are dependent on Windows and are not supported by the operating system in real time. We are working to make these changes to the range of functions in real time.  I'm sorry for the inconvenience.  If you do not need to use the ZIP screws, then you should be able to transfer the data to a host computer and then call the screw ZIP from here.  If you have other questions about this please just after them here and we will help you.  Have a great day!

• BlackBerry-sign gives me "error in opening zip file".

  We have BB 10 Native application that has some setting we want to customize for each customer. Example of database server, etc. User\Pass. The settings are stored in the QML file so it can be read by the App while running.

  In order to allow customization based on demand, we decided to create the ussigned of the bar of the package version using blackberry-nativepackager.  Bar file is Zip file, when these details provided by the customer, we simply decompress .bar file, the zip again and QML file using a utility such as 7 Zip.

  But after that when I tried to sign the new file .bar using blackberry - sign it gives me "error in opening zip file". File has permission and it is not corrupt. I don't know why blackberry-signatory dislikes the new bar file. Is native Packer doesn't something extra then creation of zip file to make it work with blackberry signer?

  I believe that this solution I was looking for.

  We also have the database version 10.2.0.4 that the spfile even uses everyday cold backup of the database.

  also, I put the 777 permission to the file.

  OK, I guess there will be corruption of the SPFILE as if edited manually or in any other cases too.

  You have a backup of SPFILE? backup of the file PFILE or?

  then starting using this SPFILE, if any backup then start with PFILE and then create SPFILE from PFILE.

  Otherwise, you can copy the contnets of the parameters of the alert log file initialization and paste in the editor and the instance of starutp.

  These are the options.

• loadjava error when opening the file:-fix java.io.FileNotFound of Exception

• Creating movie SWF errors file

  Dear Forum,

  CS5.5 running and I have errors when I publish, debug or listen to samples:

  Creating SWF movie to the error file.

  Make sure that the destination file is not read-only or opened by another application. Also, check that the file name is too long.

  This error appears constantly and sometimes didn't appear at all. I sometimes find myself hammering Alt + Maj + F12 for twenty times before we get to "through". I've seen a number of subjects passed on this issue, but none of the solutions presented here seemed permanent solutions. Does anyone have an idea? It is kill productivity, really.

  Thanks in advance.

  Disable that and also clear your ASO cache in the same menu as you test your movie from. See if you have a cache problem.

• 'write on worksheet' VI error: file already open

  I get this error when I write in a CSV file: I save data there permanently... Well, I programmed it stores about 100 points in memory and writes every 100 points.

  When I open the saved file in Notepad for example to preview, Labview returns error "File already open" and so he can't write.

  isn't this weird? aren't you just cached the file when opening information? How can I fix it?

  I use the VI "write on the worksheet.

  Thank you

  Maybe when you get the error, store what you were going to put in this file in memory or a temporary file.  Displays a dialog box that does not stop your program to tell people, don't not to open the file.  When your program detects the file is therefore more open giving the error, and then write about everything that you stored in the memory (or read about in the temp file and write) before adding the latest data to the file.
