What is a serialized file?

Hi all!
I googled, but I seem to only be able to find out methods involving a serialized file, but I can't find out exactly what it is to start with. Any explanations/links welcome.
Thanks!

  • Reading data from a serialized file(Data is in special characters &symbols)

    Please help me.... I struck up at reading data in a serialized file. It is a text file with some special characters. My question is - Is it a real serialized file or some bad file? If it a real good one please tell me which method i have to use to read? Actually i have to read records with time stamps from this file and have to do some calculations on them.

    It looks like it might contain serialized Java objects, since it contains Java class names. Have you tried reading it as such to see what happens?
    Or are you asking how to do that? In which case why not just start with the code in the Java serialization tutorial and go from there?
    Or did you not know there was such a tutorial? Google keywords: "java serialization tutorial".

  • Manipulate a object serialized file when the .class file is missing

    I want to know if it is possible to recovery the object when its class file is missing! I guess it needs to manipulate the file and extract the values and ask user to name the values, after that, create a new class file for future use. However, I don't know how to manipulate the object serialized file. I really appreciate any hints you guys can give

    I suppose if you created the class file, with the same name, package, and unique serial ID, fields, etc, it can be done.
    Another option is to not use serialization if you are just trying to recover the data. Again you would need to know what the datatypes of the fields are to know what it is you are trying to read, how to parse serialized data, etc. Some Objects are easy to read, like Strings. The more complicated ones are the simple datatypes.

  • What does the open file dialog do 'under the hood' and is there a way to simulate it

    What does the open file dialog do 'under the hood' and is there a way to simulate it?
    I have a bug in my code (that I've posted about before, here) which I can't fix at the moment, but I do have a workaround.
    Briefly, the bug:
    I call a dll from a function node, to initialise and run a spectrometer. If I start up the PC, LabVIEW and run my vi the code runs without complaint, the first call to the dll to initialise the spectrometer doesn;t return an error but the spectrometer is not detected either.
    I've tried various solutions, see the link above, and none work
    The workaround:
    If, at any time before running the code containing the function node I open an 'open file' dialog window, select the dll and click ok/hit enter then everything is fine. When I run the main code the spectrometer is detected.
    I use an express vi to open the file dialog, I specify the start path and file name as constant inputs and just click ok/hit return when the dialog pops up. I don't do anything with the dialog outputs. In fact the vi that contains the open file dialog can be run before the project containing the bug is even open.
    I have to do this everytime I turn the PC on.
    So, either
    1) Can somewone suggest a fix for the original bug?
    2) What is the easiest way to simulate the enter keypress when the open file dialog pops up
    or
    3) Can someone tell me what the open file dialog does under the hood that somehow causes the dll to work and can it be simulated in straight LabVIEW
    I suspect that the dll itself is dodgy ( I have in the past talked to the supplier but not got very far, and I will try again but I would like a quick, temporary solution too). I'm guessing that the file dialog is making some kind of check on the file, and possibly registering its presence with the OS (winXP). I tried using the file/folder exists vi to see if checking the file like that worked but no luck.
    Any help greatly appreciated.

    Hi David
    I am very conscious about thread hijacking but this sounded like my issue so I hope you dont mind me asking about your issue. I am hoping that you have a spectrometer from the same vendor as me and its not just me seeing an Error 1097 issue. My spectrometer is from a company called Stellarnet.
    So far I have unable to get it to work with other VIs. There is one condition where I can get it to work but its no good for me.
    Case 1
    I open the VI in a fresh labview environment with no other VIs in memory. The code runs with no issue.
    Case 2
    Labview is not opened. I double click the spectrometer VI in windows explorer.  The VI opens but it fails to run resulting in Error 1097. Personally, I dont see the difference between this and Case 1 above and yet it fails.
    Case 3
    If I already have other VI's in memory and try to load the spectrometer VI and run it fails with Error 1097. This case is the one that most important to me. I have a test executive that will load test VIs dynamically and I can't get this to work. Same problem Error 1097.
    I wanted to share what I have seen with you and to let you know that maybe somebody else has the same issue. I am convinced its the DLL but the vendor dis-agreed saying it was LabVIEW. I couldn't convince him otherwise.
    Thanks in advance

    How do I add a movie from my laptop to iTunes, what should be the file extension.

    The extension is usually .mov, .m4v, or .mp4.   But you can't just change the extension.  The movies have to be encoded in a particular fomat.  Anything downloaded from iTunes or plays in Quicktime player will be fine.

    thank you

    It's the level of compression. Lower number, more aggressive compression, more visual artifacts.
    Aside from that you should never use jpeg as a working format. The compression is destructive and cumulative, and the file deteriorates every time you resave it.
    Use TIFF or PSD, and if you need jpeg save out a copy as a single final step.

  • What is a imoviemobile file?

    What is a imoviemobile file? in imovie for iphone i'v generated an my projetc.imoviemobile file and i can't read it?

    I don't know if this is a few years too late but to get into a iMovieMoble file you first need to get it onto your computer if you haven't done already which it looks like you have.  The latest versions of iMovie won't interface anymore with imovie for moble, this is going to be fixed someday they say but in the mean time if you want to get your clip out you first want to copy the iMovieMoble project and then change the extention to .zip  This will then allow you to extract the zip into a folder and inside are all your renders and clips that go into making that project. I wish there were a faster way like the right click and say show package contence but it's a different kind of file than that.

  • What is a dmg file?

    What is a *.dmg file?  I am showing one in my Finder called ABEIDSNCS4_LS1.dmg and it's an image file.  My concern is that the size is 1.16 GB. What could this be and can I delete it?
    Thank you.

    .dmg files are Disk Images. Basically they act like a separate volume on a hard drive. Often when you download an application from the Internet it comes on a disk image file. Once you have run the installer, you can delete them by dragging them to the Trash and emptying the Trash. Another way would be to hold down the control key on your keyboard when you click on the .dmg file and select Move to Trash from the menu that appears. Again you'll want to empty it.
    Best of luck.

  • Copy Interruptus - what is a ".DS_Store file"?

    Hi, I'm running an old MacBook Pro (3+ years old), and I'm going to try install an SSD drive to speed this tired, but most wonderful critter up.  I've already backed up the HD (500 GB), but the SSD (240GB) is smaller so I'm trying to move files off.
    I thought I might strip out everything that wasn't applications and the operating system and later put back what I really need but I keep getting these messages about ".DS_Store" files, as I copy different folders and the copying keeps comes to a crashing halt.
    Is there something I can do or do I need to grab an expert? 
    And I apologize but I'm pretty much a luddite at the technical details & computer code, so can someone explain ssssslllllloooooowwwwwyyyyy.  LOL
    Thanks,

    Hi All, I have two questions. First of all my CS3 is saying that it is installed on more than one machine, is there a way of seeing what machines my serial number is registered to? If i want to buy another CS3 serial number how do i go about it? I cannot afford to move to the creative cloud.....

    there's no way for you to identify which machines have or had cs3 activated, and you can no longer purchase a cs3 license from adobe.
    you can request an activation count reset (Contact Customer Care) and deactivate your cs3 on all your computers.  you can then install and activate on up to two computers.

    That's the firmware telling you it can't find the operating system it's been assigned to boot from.
    It could be because it forgot somehow, or the operating system is no longer there or readable or the hardware holding the operating system has failed.
    Hold the power button to force a hardware shutdown, then reboot holding the option/alt key held down on the wired or built in keyboard, icons will hopefully load on the screen and if OS X appears, click the arrow to boot from it.
    Once in OS X, head to System Preferences > Startup Disk and select your boot drive so it can remind the firmware.
    If there is no OS X boot volume, just recovery or Bootcamp (if Windows installed) then you need to perform more work.

  • I've got a file that is getting auto-created on my desktop, that is a .textClipping file with a very long series of numbers and letters as the filename (and of course, as the clipping as well).  Is there any way to tell what is creating this file?

  • What is the minimum file system access needed to run ODI 10.1.3.4.0 client?

    Hi ODI discussion folks,
    I have a couple of questions from an Oracle partner that I'm trying to find a definitive answer for if possible. The partner is setting up ODI 10.1.3.4.0 for a customer who insists that the absolute minimum amount of access to the file system is granted due to corporate security policies.
    I have checked the bundled ODI documentation but couldn't really find anything about file system permissions needed to run the ODI client. I was pointed towards the "Setting Up Security for an Integration Project — What to Consider" document but this does not mention a great deal about how much access to the file system is needed for the ODI client to function.
    What the partner is asking is the following:
    "1. What are the minimum file/folder permissions needed for the ODI client installation? I'm installing at xxxxx
    and their machines have to be locked down as much as possible.
    2. Say you have 3 users all wanting to run integrations etc and the Master and Work
    repositories have been set up. An admin installs the ODI client but doesn't
    create the connection to the Master repository. What are the minimum
    file/folder permissions required on the client machine to:
    a) create the connection to the repository
    b) run any subsequent integrations?"
    If anyone can advise on this then that would be much appreciated.

    Hi Craig,
    How are you?
    Let me try to contribute a little....
    1) The minimum requirement is for its own installation directory, there is no reason to have access to other directories unless if it is necessary to read files from some other directory at the client
    2) Again only to its own install directory. The connection setting is recorded at \bin install directory. After that, all information are recorded at repository, there is no client work.
    Be free to contact me by email or phone if you have any new doubt. You can get my email from my profile.
    Does it respond your doubts?
