Open Create Replace problems with saving file patterns

Hello, I got a problem with open/replace/create function. Could you please clarify each function how it works? As you can see in my file, I try to save into the specified file path. The values appear in the text file but when I change some values in the data mainstream, it replaces the old value it has been. I want to have the whole data in one file till I close it and open another file for the operation.
How can I do it??
Thank you

Hi,
I can't see your VI as it is in a newer version of LabVIEW than I have, so if you want any more specific help you'll need to save the VI as a previous version. (File -> Save as previous version) I have LabView 2009.
However, I have made a quick little example you could use. You don't need to use Set File Position if you use Shift Registers, as shown in the attached picture.
David.

  • Problem with saving files

    Hello,
    I use FW since 2002,
    I am having an anyoing problem:
    when I save the file, let's say logo.png, I save it in the folder of my client clientxxx
    I want to export the file into jpg, and I try to export and by default the export command opens the desktop and I have to navigate all the way to the folder where the clientxxx files are, why? that didn't use to happen in the past versions, is anoying because everytime I have to save the logo lets say a modification I have to navigate to the correspondent folder.
    THanks

    Which Fireworks version do you use?
    8? CS3? CS4?
    I think that Fw works in this way (some of its logic):
    1) If you have saved client-logo.fw.png in folder D:\MyClients\Client1\, then exported the file as client-logo.jpg in folder D:\MyClients\Client1\ and then saved the .fw.png file again, next time you will open client-logo.fw.png and try to export again, it will automatically go to D:\MyClients\Client1\ -- the PNG file will "remember" where you exported it last!
    2) If you have saved client-logo.fw.png in folder D:\MyClients\Client1\, then exported the file on the desktop, then saved the .fw.png file again, next time you will open client-logo.fw.png and try to export again, it will automatically go to desktop for the exported JPG version! -- the PNG file will "remember" where you exported it last -- like, Desktop!
    3) If you have saved client-logo.fw.png in folder D:\MyClients\Client1\, then exported the file on the desktop, then you DID NOT save the .fw.png file again, next time you will open client-logo.fw.png and try to export again, it will automatically go to the *last* folder you have used to export some Fw PNG file! It could be Desktop, My Documents, or D:\MyClients\Client1\.
    These are the basics... If you think Fw should behave in a better way in this area, please send your idea to Adobe:

    Fireworks dev team will surely listen to you!

    I'm on Mavericks 10.9.01 on a MACPRO. Whnever I save a file on my Philips 273EL I am unable to see the files names in the various folders I want to save, while the folder Icons and names are visible.
    If I open any folder again its content names are totally unreadable
    How to solve this problem if anyone has it?
    I already find very unuser friendly the toolbar without colours as the colors helped before and I do not understand what is good about that change ...
    With the same monitor using a Snow Leopard system this doesn't happen. Hence I suppose is not an hardware problem but something in the Mavericks system I might be able to adjust with so help from this community.
    I hope someone can help
    Regards to all

    I already find very unuser friendly the toolbar without colours as the colors helped before and I do not understand what is good about that change ...
    The only way to add color back is using a program to hack the system. I keep sending feedback about the lack of color.
    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

  • Error 7 occurred at open/create/replace file

    Hello,
    I have searched the forum and could not find any useful information regarding my problem, so hope you may shed some light. MyVI can create a new csv (text) file by using the time to name the file, so every time the new file will be created with a different name and file path is not a relative path. I can run the VI in both development environment and stand along executable without any problem. But, 
    One of my colleagues  cannot run the executable exe on her machine because Error 7 occurred at Open/Create/Replace File in xxxx.vi Possible reason: LabVIEW: File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.
    My question is why only she cannot run this exe on her machine. I have checked a few different PC in my office and all of them can run this exe without problem, so I am pretty sure the code is fine.
    I have already ask her to do,
    Run the executable as administrator
    Save the new file to other drives (not C: drive)
    but she still cannot run the executable. I dont think this is a premission issue, otherwise, LabVIEW would give a different error, Error 8 I believe.
    Both her PC and my PC is running Windows 7 professional 64-bit. The only difference I can see is that she is based in US and I am based Australia. Does anyone have any idea? Please help.
    Thanks,
    Sherman

    I’m not sure but expecting like below,
    As you said, your creating file name with Time. Make sure file name is correct and there is no special characters (like, / or : ). If your formatting time to string with “Format Date/Time String.vi” (while creating file name), based on UTC format, string will change.
    UTC format specifies if the output string is in Universal Time or in the configured time zone for the computer. If TRUE, date/time string is in Universal Time. The default is FALSE.
    Make sure you have access rights to create files into mentioned folder. Try to create new file manually.

  • Error 5 occurred at Open/Create/Replace File in Write spreadsheet String.vi

    Hi everyone,
    can anyone help me with this problem?
    "error 5 occurred at Open/Create/Replace File in Write spreadsheet String.vi "
    I've been using this part of the program for over a year an suddenly this error occures. But not always, mainly at the very beginning of my tests when the file should not be open.
    Info: I'm using a realtime PXI-System. Maybe the amount of data can cause the problem? (about 2MB)

    Hi Meike,
    is the file opened by a different program? Do you try to access it by FTP in parallel to your VI?
    You could use basic file functions instead of WriteSpreadsheetFile. That way you could open the file before starting the loop, keep it open all the time and close it once you're finished - with the added benefit of easier error handling…

  • Bug in Open/Create/Replace File

    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 workaround that will make it work properly for now. I just wire an Error Out after the Open/Create/Replace File (second snippet). Is this a bug?? Am I doing something wrong?? 
    I've got a lot of code that uses this to test to check for existing files and then wire the output to a case statement. I also know there is a Check if File/Folder Exists.vi available. I would hate to spend a lot of time changing all my code if this is a known bug and it will be fixed in the next update. If it is not a know bug, where can I submit this??

    Its not a bug. You have race condition between indicator and close ref.

  • Odd Open/Create/Replace File Behaviour

    Hi all,
    I will make my question as general as possible as I believe someone must have come accross this behaviour before. I am using the Open/Create/Replace File function to programmatically open a file, by giving a path input created in an earlier vi. The odd behaviour I observe is that although Labview returns Error 1 when I give my file programmatically, it reads the file OK if I give it as a constant. The path constant I give is exactly the same as the one I am tryinng to give programmatically.
    Any suggestions? Is it to do with some string formatting problem? I have attached my portion of VI dealing with the path_in section.
    Thanks for your time,
    Regards,
    Harry

    Wild guess: You need to use "build path" instead of "concatenate strings" to built the path.
    (Also use a path diagram constant (not a string!) for "c:\ni-rt\" and get rid of the "trim whitespace" and "string to path".)
    See if it makes a difference. (build path is OS independent while string operations are not).
    Never operate on paths as strings. There are very few instances where that would be appropriate.

  • "open/create/replace file"

    Under the file I/O functions palette there is a vi named "Open/Create/Replace File.vi". My application builder has trouble with this file name. Is there any reason  to name a vi with /'s? Seems to me that is not a valid file name convention in Windows.

    Yes it's a pain.  Yes it's not very compatible.
    Yes you can rename it to include "-"s instead of "\"s and stick it in the same llb as the original.  I always make a copy, draw a nice big red X on the old one and leave them side-by side in my VI.lib folder.  That way I get around the problem.....
    Hope this helps

  • How to use Open/Create/Replace File.vi

    How to change Open/Create/Replace File.vi to Open File?

    Use the routine Write Characters to File.vi found under the File IO palette. It has a boolean control on the front panel. If this is set true, data is appended to the end of an existing file, or a new one is created if the file doesn't exist. If the control is set to false, the file is always created new--overwriting any existing file with the same name.

  • Modification to Open/Create/Replace file vi in Labview

    I'm a relative newbie to LabView so this modification described below is a daunting task for me, given the complexity of the block diagram in the Open/Create/Replace file vi .
    I want to change the dialog box and choices when you have selected a file that already exists from Replace or Cancel as the only 2 options to:
    ReplaceFile  AddToExistingFile  RePromptForANewFile QuitApplication  (this 4 option choice is my first preference)
    or at minimum
    ReplaceFile  AddToExistingFile  Cancel (adding AddToExistingFile as an option) 

    First of all, you should know that playing with the VIs supplied with LV is not always a good idea and open\create\replace is an example for a particularly not-good-for-editing VI. In any case, you should not overwrite the original.
    In this case, you can use Edit>>Find to find the 2 button dialog you're seeing. When I look at where it's located, it's enough to discourage any thought about changing the VI. At the moment it has a single output (overwrite?). You could replace it with a subVI which will have all your buttons, but you will need to add code to handle the extra buttons, which can be very dangerous.
    You may wish to create a much simpler logic instead which will do what you want yourself (using the VIs in the File I/O>>Advanced palette, like Open File and File properties), which will probably be safer.

    I believe the Report Generation Toolkit has a subpalette for Macros but I don't know what you can do with it.  The Report Generation toolkit comes with some versions of LabVIEW 2014, I think Full and Professional, but was separate before that.  At the end of the day ActiveX will need to be used somehow.
