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 file open/create/replace FPGA

    Hey guys,.

    I'm having a problem where, when I try to use reading worksheet VI in my RT Host Application, it returns error code 7 (can't find a file or folder does not exist) when it calls the function of file open/create/replace. The feature works very well when used in a standalone VI that is not part of the FPGA project and I made sure that my path is correct, but for some reason, it does not work in my FPGA application. I have placed sensors and ensured that the correct path to the file is linked to the input function but the error persists. The refnum output file returns 0, not "not A Refnum". Does anyone have an idea on why I get this error or if I'm the only one? Any help would be appreciated. Thank you.


  • 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:

  • CC of Dreamweaver for Mac strange new files always created

    Hello

    I bought iMac and it's my first Apple product. Now I have installed Dreamweaver and a few other apps that I use for web design and eveyr time I save a file, if its, PHP, HTML, CSS, PSD, PNG, I get the same file name created next to the source file. For example if I save the SAMPLE file. PHP another file called ._EXAMPLE. PHP is also created. Is it possible to turn this off or these files needs to save for Mac?

    Thank you and sorry that sounds like a question of noob, but never used Mac OS X.

    You should be able to turn off your hidden files to remove.

    Files starting with a. are supposed to be hidden on the Mac, they are the files "users should not need to futz with these.

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

    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.

  • Replacement of a few pages in my PDF is strangely small file size

    Hello!

    I recently reviewed a document 400 printing pages by replacing 7 pages in the PDF file and it is the strangely smaller file size!

    The original has been exported as a PDF of a book consisting of 61 files InDesign (184 MB) file.

    The review was one more round about way-opening and export files individual InDesign 6 to the appropriate output settings and replacing 7 unique pages in the PDF file and save as a new version number (108 MB).

    The reason for the series on how to change the project is because all files are stored on a server and it is easier to make simple changes while working remotely.

    No idea what is causing the size of the file to be much smaller?

    Thank you for taking the time!

    Probably you have registered under a new name (SAVE AS) and before you used to REGISTER. Save the leaves wasted space, save as it recovers.

  • Photoshop CS3 freezes when opening/creating new files

    My system: Mac OSX 10.5.8, 2.1 GHZ Intel Core 2 Duo, 1 GB 667 MHz DDR2 SDRAM

    Whenever I try to open the files or create new files, the program crashes / freezes. I have Google'd and found similar problems, yet I have not yet capitalized on the realization of a complete restoration. I recently installed a new driver of LEXMARK printer and I found that this could be my problem. I started to remove printers drivers and preferences of adobe to solve half of my problem. CS3 is now blocking half the time when you create a new document and crashes everytime I try to open a document. Sometimes when I'm really able to start a new document, I can open documents, which is rather strange. I must be missing something to delete of what is the driver installed, or there must be something else I'm missing.

    I uninstalled and reinstalled, but that did nothing. I created a new user account and tried to work the program in there, but it still crashes. Illustrator and InDesign work very well. I need immediate help to continue the work for the clients, please help as soon as possible. Thank you.

    Since us don't know not what the Lexmark driver leads to freezing, we do not know if reinstalling it reintroduced the problem or not.

    You should probably talk to Lexmark on the printer driver and the problems it poses.

  • 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?

  • Photoshop will not open/create new files, can't resize images etc.

    Hi all.

    So I'll start with the basics; I use Photoshop 7 (and Yes, I use it for a reason, I'm not interested in the migration to this jumble of creative cloud new $1000), we Australians get us torn a new and I am happy with the $50 I paid for my copy years ago. (Please don't tell me the solution to my problem is simply to level and go bankrupt. Yet once again, I am using 7 for very long without problem).

    I use the 7 for almost a decade without problem. I stick with it because so far, he has done everything that I need, has been reliable up to this point, and my plugins work correctly with the newer versions. I also use a system more older-spec (Windows XP, 3 GB of ram etc.) I do a lot of work with former game engines, Source engine etc.

    The question that I have doesn't seem to be Photoshop-7 States, however, there are many threads on this point that remained and arrive in CS3 etc. and modern copies as well. I uninstalled and reinstalled nothing doesn't. Basically, I can't open the reliable files with it.

    If I click with the right button on any image file in Solution Explorer and click 'Open with-> Photoshop', photoshop will launch, however it does not open the file. I double checked to make sure that the file wasn't just opening offscreen, however it is certainly not opening at all (like the "close" option does not become available).

    If I launch photoshop manually, click on file-> open-> it will open this file, BUT it will not more files open after that.

    She also is very very picky with simple controls, such as if I hit CTRL + T to go in processing mode and then try to resize an image, I have to click and drag the corners at least 5 - 6 times before it will recognize that I do, and it will also ignore the resizing I perform and break back to normal. Sometimes, I have to click more than once things to get them to sign up. This does not occur with any other software etc, so I excluded that there is a problem with my mouse.

    This happens only one day, and I can't think of any particular system changes it will likely cause (IE no abnormal plugins installed recently, no major changes in hardware or software). Unless my keyboard has a stuck key or something strange, I am absolutely at a loss

    Is there someone who can help me or has heard of this problem?

    I'm a fool.

    I suppose the work disk was full or something else. A simple reboot seems to have solved the problem. (I often my system running up to 64 48 hours at a time without that it recharges) as my working days are about 36 hours straight, so it could just be a constraint of XP.

    I hope that this solves the problem for someone else who she sees. Restart your pc from time to time, give him a table open memory to work with.

  • Problem opening files PC created on the latest version of CS5 on Mac

    Hello.

    We´re a creative team in my company of four people, three users of mac and a pc user. Recently we have all subscribed to the creative cloud so that we always have the latest version of CS5, but there seems to be a problem with all the files published or created by the PC user.

    We have (mac users, all three) I tried to open the files either created or edited by the PC user and we told us that this was created by a newer version and that it is not possible. Try to understand why this message occure when all three Mac where updated with creative cloud after the PC user.

    your title is confusing.

    the pc user uses cc 2014 apps, correct?

    mac users use cc 2014 apps, correct?

    If so, there should be no problem.

    If someone is using cs5 to try to open a file created by an application of 2014 cc, you will see the problem you have described.

    "Disk zero" was almost full warning. I deleted the files opened to create space. However, photoshop CC, crashed before that I was able to free up space. I tried several times to re - open Photoshop CC but within 2 seconds it crashes when loading. I then decided to upgrade to the 2014 version, update. He worked twice and now repeat the same problem, I have lived before update. This only happens when I'am connected under "other user account" as I had been when the accident happened first and not as an administrator. I purged the cache, more space for performance, etc. in Admin mode, I ran permission repair in public services, but when I change the user account, photoshop crashes with seconds loading.

  • Changed the behavior of opening the files of the search results?

    I've recently updated to...

    Version: 3.0.0

    Build: 290423

    When I perform a search on my workspace, I get results based on the corresponding channel. {good}

    When I click on the line of a particular file in the search panel (results), open the file (A) and the examined string is highlighted. {good}

    Among the search results, are references to other files, the string has been found. {good}

    If I click on the line item for another file (file B), firm file A and file B takes its place in the main file editing panel. {bad}

    Previously, matches 'clicked' search results would be to open the file and add it to the control panel in a new Panel. With enough screen real estate I could compare the files. However, any file opened now since search results replaces any previous search file.

    I hope that this is not a bug, but rather just a preference that needs changed.

    I guess I can answer myself.

    In the general preferences > search. I deselected 'reuse of publishers to show matches.

    And now each file opens without "reuse space Editor".
