Problems with file (save, open)

I save a file with my dates. (You can see save.vi, it's ok)
Then, I open file but it'snt ok.
Why? I don't know.
After, I'd like search one determinate value.
Can you help me?

Hola Carlos.
Lo que escribes en el fichero es texto, ya que los numeros los conviertes a string.
Para determinar el punto de algo en un fichero de texto, tienes que leerlo usando "read characters from file" y a continuacion "scan from string",que te devuelve el comienzo de la string que buscas.
No me consta que en Labview exista algun scan file que te devuelva el puntero a lo que buscas. No obstante, dado que parece que escribes lineas, puedes leerlas de 1 en 1 y buscar lo que quieres.
Espero que te sirva de ayuda

FM9: Problem with File- Save as PDF

Hello,
I'm using a German installation fo FrameMaker9 and will try to translate the actions and messages.
When I try to save my document as pdf I get a message telling me to clear the printer option "rely on system fonts only". When I do that for the Adobe PDF printer everything seems to work fine.
But: The default printer on my laptop isn't (and shouldn't be) Adobe PDF, and it looks like I have to manually select "Adobe PDF" in File->Print Setup everytime (i.e . at least once after starting FrameMaker) before I want to "save as pdf", which is annoying. Is there any way to get rid of this?
Software Versions:
FM 9.0p255
Adobe Reader 9.4.4
Adobe Acrobat 9 Pro 9.4.4
OS: Windows 7
Thanks in advance for any advice given,
JF

First thing I'd try is the SetPrint plugin, which sets your default printer to Adobe Acrobat/PDF printer in Frame ONLY.

Error while opening pdf in reader in windows 8:Can't open this file. There's a problem with file format

I have a problem with a pdf file which does not open with reader in windows 8 but it opens properly with adobe pdf reader. All other pdf can be opened in reader.But when i open a pdf(see this link for pdf for which i got error http://incometaxsoft.com/temp/Form.pdf)
it gives error as "Can't open this file. There's a problem with file format".
The same file opens properly in adobe pdf reader.You can check the pdf file which i have mentioned in the link above.But the reader which comes with windows 8 can open some other pdf in the same PC.What may be the error causing this??

This has turned out to be an enormous issue for me as I sell PDF files as ebooks. I have done a fair amount of investigating this for my system.
My files have to be compatible not just across readers but across operating systems.
To date, I have over 200 PDFs that have functioned flawlessly across Mac, PC (Windows 7 and below), Android, iPhone/iPad, Linux.
I personally test my PDFs using a variety of readers and PDF editors including
PDF XChange (my favorite)
Foxit (runner up for me and I recommend for most people)
Adobe (the bloated monster)
Nitro 9 (great for moving graphical elements around)
ABBYY
And the Nuance PDF Create toolsets
Those are off the top of my head. There are a bunch on Android that I test with too.
I am running the Windows 10 Pro Tech Preview and I have this same problem so I know it isn't fixed yet in any kind of pre-release way (-sigh-)
Here is what I've learned for my situation
The PDFs I created using NUANCE'S PDF CREATE PROFESSIONAL VERSION 8
all fail using the built-in Windows 8/10 PDF reader.
When I look at the PDF properties for these Nuance created files, the underlying engine used to write them is called "ImageToPDF". Using ABBYY it indicates their own engine as does everyone else that I've tried. It is easy for you to check to see
what created your PDF by doing a "Control D" (look at the document properties). Perhaps there's a common engine causing issues.
If I use the exact same source files to create a PDF using any of my other tools I have no issues. I checked the PDF versions made by the tools and they are all set to 1.5.
A customer mentioned being able to convert them in a way they worked by saving them without having to do any kind of extraction, but I have not been able to duplicate that. Perhaps he did a "print" which seems like it could work.
In summary, the workaround everyone is talking about, using an alternate reader, of course works. But not everyone wants to change.
The culprit I have found is my Nuance PDF Creation tools that are using the ImageToPDF engine.
I hope it gets FIXED as I really don't want to have to regenerate all of my PDF files.

Problems with File Transfers Over Firewire 800

Problems with File Transfers Over Firewire 800.
Over the past month, I have had problems when transfering files from my harddrive, over Firewire 800 to a portable drive. I usually transfer very large files (20gb or more) to the portable drives for moving files around. When I drag a file over to copy onto a drive, the transfer starts normally. If I drag more files to copy over, the computer screen goes darker and a large icon comes up that looks like a power button icon. It tells me to restart, so I have to do a hard shut down on my G5. Weird. I also get the dark screen of death sometimes when I am transfering those large files and open another application to do some work while it's copying. It's killing me. I am having to sit here and wait for the transfer to finish before I can do anything.
Any thoughts...

I suddenly encounter this error message from Fire Fox.
Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.
I uninstalled the browser and download a new version but it does not resolve the issue.
I know my hard disc has ample space. I do NOT know where to find the Profile directory to fix the read restriction box.

Unable to download from AppStore, updates,etc.Messages 'the installer is damaged' to 'there might be a problem with file ownership and permissions.' I am the owner and only user of a new MBP. What could be going on?

Is anyone having the same type of problems I'm having with Lion. I have a new MacBook Pro, received 7 weeks ago, preinstalled with Leopard 10.6.7. I didn't migrate anything from my old iMac, wanted a clean install from the Apple Store. While there, I asked for the upgrade to Lion 10.7, however their system was down.
I installed it myself, wirelessly about a week later, and Apple emailed me a receipt. Now, I've had to call support directly last week when I lost Mail, Address Book, was unable to open Preview or iTunes, among other problems. Seemed fixed after a session that baffled even the store tech. Now I am unable to download or install the recent Mac updates for Lion, from the App Store, could not install Adobe Reader, etc. Messages range from 'A network error has occured - Check your Internet connection and try again' to 'The Installer is damaged and cannot open the package. There may be a problem with file ownership or permissions.' All fail and I'll probably have to call Apple again. I am frustrated beyond words. Logs 'Install's runner tool is not properly configured as a setuid tool', domain errors, 'attempt to write a readonly database, and on and on. I have barely done a thing on this computer except search online for help with these problems. Safari gives me a 'You are not connected to the internet' too often. Diagnostics disagrees. I do see wi-fi problems in the forum. Disk and permissions were fine at the beginning of the earlier problems, checked first by support tech. I'm not sure if support tech even knew. I was just happy they were fixed. Anyone have these download and/or install problems after a 'clean bill of health' so to speak, only a week ago?

Hello again.
I'm still having problems with this. I made
a simple servlet that reads from and writes
to text file. The reading part work fine on my
computer, but the writing doesn't, not even
an exception is thrown if the file exists that
I'm trying to write to. If I try to create a new
file I'll get an exception about file permissions.
I also asked a friend of mine to try this same
servlet on his windows computer and it works
as it should.
Here's the code
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class ReadServlet extends HttpServlet
     public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
          String s = "";
          PrintWriter out = response.getWriter();
          String docroot = getServletContext().getRealPath( "/" );
          out.println("docroot: "+docroot);
          File file = new File(docroot+"test.txt");
          if(file.exists())
               s = readFile(file);
               out.println(s);
          else
               out.println("file not found");
               //file.createNewFile();                    // causes exception
               //out.println("new file created.");
          writeFile(file, "written by servlet");

          out.println("and see if it contains text 'written by servlet'");
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException

          try
               fis = new FileInputStream(file);
               bis = new BufferedInputStream(fis);
               dis = new DataInputStream(bis);
               s = dis.readLine();
               fis.close();
               bis.close();
               dis.close();
          catch(Exception e)
               e.printStackTrace();
          return s;
     private void writeFile(File file, String s)
          FileOutputStream fos = null;
          BufferedOutputStream bos = null;
          DataOutputStream dos = null;
          try
               fos = new FileOutputStream(file);
               bos = new BufferedOutputStream(fos);
               dos = new DataOutputStream(bos);
               dos.writeChars(s);
               fos.flush();
               bos.flush();
               dos.flush();
               fos.close();
               bos.close();
               dos.close();
          catch(Exception e)
               e.printStackTrace();
}And if someone wants to test this servlet I can
give a war package.
Any advices?

Problem with file vault

One of the desktops on my macbook 2007 steel case will not open.
The message i get on screen at login is that there is a problem with file vault.
my dissertation is on that desktop.
all other desktops/user accounts are unaffected and i have admin permissions on them
i recently upgraded to osx 10.9.4
how can i get back in?
chaiman 22

If you restored the account to which the FileVault protected Home folder belonged, then you need to log into that account and enable FileVault.
If you just need access to the data in the FV protected Home folder, then locate the sparsebundle disc image file that contains the encrypted folder. Double-click on it as if to mount it. You will then need to enter the FV password associated with the account to gain access (this is NOT the admin nor login password.)

Problem with file descriptors not released by JMF

Hi,
I have a problem with file descriptors not released by JMF. My application opens a video file, creates a DataSource and a DataProcessor and the video frames generated are transmitted using the RTP protocol. Once video transmission ends up, if we stop and close the DataProcessor associated to the DataSource, the file descriptor identifying the video file is not released (checkable through /proc/pid/fd). If we repeat this processing once and again, the process reaches the maximum number of file descriptors allowed by the operating system.
The same problem has been reproduced with JMF-2.1.1e-Linux in several environments:

Its a bug on H263, if you test it without h263 track or with other video codec, the release will be ok.
You can try to use a not-Sun h263 codec like the one from fobs or jffmpeg projects.

NT security problems with file I/O

I have 2 problems with file I/O. When I read from a file I use the getAbsolutePath() method that is part of the File class to find what directory the files are currenlty. The problem is that the returned path says that the file is on the desktop no matter what directory the file really is in. The second problem is that I am unable to save files anywhere but the desktop. I must run the class files from the desktop too to get it to work.
I am using NT 4.0 for development. I'm guessing that these problems might be NT security related. Could someone help me?
