Why my text is written to a file on the SD card seems to be corrupted

The files created by an application of BB on the SD card cannot be seen with the Windows Notepad.

I have an application that has created some text on the SD card files. However, files seems to be corrupted under windows, but the BB app can read files very well and it takes exactly what is written. The BB OS encrypts the files?

Here is the code

                fconn = (FileConnection) Connector.open("file:///store/home/user/Config.doc", Connector.READ_WRITE);

                os = (DataOutputStream) fconn.openDataOutputStream();

                writeString(os, "1234567890");
                writeString(os, "abcdefg");

                os.flush();
                os.close();
                fconn.close();

    private void writeString(DataOutputStream os, String s)
    {
         try
         {
             os.writeInt(s.trim().length());
             os.write(s.trim().getBytes());
         }
         catch (IOException e) {}
    }

If you see a .rem extension added file name, this means that the DRM file and can only be decrypted by this BlackBerry. This can happen if encryption is enabled for the media card (take a look at the Options-> Security-> Encryption). In addition, it is possible to control programmatically if the files that you create will be encrypted or not: If the FileConnection is an instance of ExtendedFileConnection you can then call various interesting methods in this regard.

  • Can someone explain why this code is not overwrite another file on the sd card?

    I use a table of bitmap with a few different images. According to a trigger, I want to change the wallpaper of the home screen blackberry in the image of my choice. I can do that for 1 single image, it is not updated while it should be. Here is my code, help! :

    * Note [D.kF] is an array of Bitmap

    * D.bgNumber evolves according to the program (that is to say, it takes a different image)

    Card graphics graphics = Graphics.create (D.kF [D.bgNumber]);

    Encoder JPEGEncodedImage = JPEGEncodedImage.encode(D.kF[D.bgNumber],100);
    try {}
    ExtendedFileConnection fconn = (ExtendedFileConnection) connector
    .the ("file:///store/home/user/pictures/image.jpg",
    Connector.READ_WRITE);
    fconn.enableDRMForwardLock ();
    {if(!fconn.) Exists())}
    fconn. Create();
    }
    OutputStream os = fconn.openOutputStream ();
    OS. Write (Encoder.GetData ());
    OS. Close();
    fconn. Close();
    } catch (Exception e) {}
    System.out.println ("output file error:" + e.getMessage ());
    }

    HomeScreen.setBackgroundImage("file:///store/home/user/pictures/image.jpg");

    Sorry, I borrowed this code for my own purposes, so I'm quite foggy as to its functions. I have just made a run through in the Simulator and noticed that the image has been "locked" in the actual file. He says DRM Forward Lock. Now I read a little about it and I thought it was a necessary element of this encoding.

    In any case, I reduced on the line of lock forward and his now appear correctly as the home screen. So I guess its resolved, but, you, what is the purpose of the lock?

  • Why then I right click on my files in the project area/bins in the new Premiere Pro CC 2015?

    I recently updated my first to the latest version (Release 2015.1; Adobe Premiere Pro CC v9.1).

    Since the update, I just couldn't do a right-click on my sequence files in my part of the project. I am able to do a right click on the clips and other files, but not the sequences.

    I use a right click on the clips to quickly duplicate the sequence in order to save previous versions of my changes.

    I can still duplicate by selecting the sequence, then go in Edition > duplicate... but right click is just so much more practical and useful while I'm editing.

    Is there a particular reason why a right click is no longer available on the sequence files in creative projects?

    R. Hernandez

    I just discovered this problem as well where I could not right click on the clips in my calendar.

    What worked for me was to change / reset my workspace.

    Seems to work fine now.

  • Why my lightroom does not find my file unless my camera card is in the card reader

    I imported the photos from my camera card and created a collection.  I then remove my the USB card reader.  When I try to edit photos in lightroom, it says "file is not found."  It is the folder if I set my camera card in.  It seems that my collections are stored on the card in my camera (is this possible?), but I don't know how this could happen or how to fix it. Help?

    HI Robert,.

    It seems that when you imported the images from the card you added in the catalog instead of making a copy. in the window at the top import, we have the option 'copy as dng', 'copy' , 'move', 'Add '.

    choose copy, and then on the right, we will get the destination Panel. in which we can choose the destination in which we have to copy the images from the card.

    Thank you

    =============================
    I do not think that the 'Read only' attribute of your
    file is the problem... in fact, it is typical.
    All files on my XP Pro system have a
    Square marker (not checked) to playback
    Only the check box.

    If you want to experiment the following article...
    explains how to change the read-only attribute.

    Now for the photos... lets make an experience.

    Open your folder my pictures and create a new folder...
    File / new / folder... (more on this shortly)

    Insert your SD card into your Media Player. Do not forget
    to slightly press the card at the bottom of the slot.

    If the Autorun screen opens, close it.

    Reach... My computer or on the removable click
    Disk that corresponds to the location of your card is in.

    In the menu... Choose... Explore.

    You should be able to see the directory of the card.

    Open the folders and find pictures.

    Reach... Edition / select all... then... Edition / copy.

    Right click on the new folder that you created in my
    Images, text and the menu... Choose... Dough.

    Transfer files or you still receive the error?
