What trick to get SD card reader to read jpeg files from SDHC card

I need to be able to read jpg files directly from SD HC cards into the iPad. This is not working. I have tried bunches of things. The card clearly contains 164 files. The iPad just cant see them... What things can I try to make the card visible to the O/S?

OK, I found the actual problem. SDHC cards do work. The problem is the file naming convention. MAC requires the old DOS 8.3 format. in other words the file name MUST BE XXXXXXXX.jpg (eight characters or less, no special characters. just letters and numbers) followed by a period, followed by a 3 letter file descriptor. Those file names work fine. without the whole ball of wax, NO GO.

    What are the commands available to read a file from application server and store the file into an internal table?

    Hi,
    To read a file from an Application Server to an Object there is a command in ABAP called <b>READ DATASET</b>. After that file is transported to that object you have to do a loop and put that data in an Internal Table.
    This statement exports data from the file specified in dset into the data object dobj. For dobj, variables with elementary data types and flat structures can be specified. In Unicode programs, dobj must be character-type if the file was opened as a text file.
    For dset, a character-type data object is expected - that is, an object that contains the platform-specific name of the file. The content is read from the file starting from the current file pointer. After the data transfer, the file pointer is positioned after the section that was read. Using the MAXIMUM LENGTH addition, the number of characters or bytes to be read from the file can be limited. Using ACTUAL LENGTH, the number of characters or bytes actually used can be determined.
    In a Unicode program, the file must be opened with an arbitrary access type; otherwise, an exception that cannot be handled will be triggered.
    If the file has not yet been opened in anon-Unicode program, it will be implicitly opened as a binary file for read access using the statement
    OPEN DATASET dset FOR INPUT IN BINARY MODE.
    . If a non-existing file is accessed, an exception that can be handled can be triggered.
    Influence of Access Type
    Files can be read independently of the access type. Whether data can be read or not depends solely on the position of the file pointer. If the latter is at the end of the file or after the file, no data can be read and sy-subrc will be set to 4.
    Influence of the Storage Type
    The import function will take place irrespective of the storage type in which the file was opened with the statement OPEN DATASET.
    If the file was opened as a text file or as a legacy text file, the data is normally read from the current position of the file pointer to the next end-of-line marking, and the file pointer is positioned after the end-of-line marking. If the data object dobj is too short for the number of read characters, the superfluous characters and bytes are cut off. If it is longer, it will be filled with blanks to the right.
    If the file was opened as a binary file or as a legacy-binary file, as much data is read that fits into the data object dobj. If the data object dobj is longer than the number of exported characters, it is filled with hexadecimal 0 on the right.
    If the specified storage type makes conversion necessary, this is executed before the assignment to the data object dobj. Afterwards, the read data is placed, byte by byte, into the data object.
    System Fields
    sy-subrc Meaning
    0 Data was read without reaching end of file.
    4 Data was read and the end of the file was reached or there was an attempt to read after the end of the file.

    Hi all,

    Hi Sutirtha,
    Initially I have started the agent.sh giving the agent name <agent name>and port number 20910 and defined it in the topology manager it is showing that the agent test is succesful. Then I tested a particular Data server against that agent and the test was successful.
    After this we had stopped the agent and restarted it.
    However now suddenly the testing against the remote agent is failing with the following excep:

  • Cannot get LR4 to read xmp files from a Nikon D4, Reads the D3S xmp files fine.

    I am doing some editing work for a magazine. The lead editor had issues with adobe camera raw viewing some of my edits. The xmp files are there but for some reason they are not loading. We narrowed it down to just the Nikon D4 files. I just had her download a trial version of LR4 and we are getting the same issue. The xmp's are there in the same folder as the .nef files. Import into Lightroom, and all D4 files do not show my edits.
    We are both running Lightroom 4.3, Camera Raw 7.3.

    LR may or may not have up-to-date XMP files if you haven’t explicitly written them.
    I have not encountered the XMP-ignored-if-timestamp-before bug but I believe it is the actual Windows/Mac file-modification timestamp, not something inside the file.
    My suggestion is to write all the XMP files, again, and resend those to her.  That way you’ll know their contents is current and that their timestamp will have been updated to something after the raw files timestamp.  If the images are all in oen or a efw folders then the easiest way to update all their XMPs is to right-click on a folder in Library and choose Save Metadata.  If the photos are more scattered but you can select them all in the Library grid view just right-click on one and choose Save Metadata to Files—make sure it says Files not File.
    I assume both of you are on Windows, not one on Windows and one on a Mac?

  • What is the 'quickest' way to read char data from a txt file

    Hello,
    What is the 'quickest' way to read character data from a txt file stored on the phone to be displayed into the screen?
    Regards

    To be even a bit more constructive...
    Since J2me does not have a BufferedInputStream, it will help to implement it yourself. It's much faster since you read large blocks at ones in stread of seperate chars.
    something line this lets you read lines very fast:
      while ( bytesread < filesize ) {
             length = configfile.read( buff, 0, buff.length );
             // append buffer to temp String
             if ( length < buff.length ) {
                byte[]  buf  = new byte[length];
                System.arraycopy( buff, 0, buf, 0, length );
                tmp.append( new String( buf ) );
             } else {
                tmp.append( new String( buff ) );
             // look in tmp string for \r\n
             idx1 = tmp.toString().indexOf( "\r\n" );
             while ( idx1 >= 0 ) {
                //if found, split into line and rest of tmp
                line = tmp.toString().substring( 0, idx1 );
             /// ... do with it whatever you want ... ////
                tmp = new StringBuffer( tmp.toString().substring( idx1 + 2 ) );
                idx1 = tmp.toString().indexOf( "\r\n" );
             bytesread += length;
          }

  • Not recognizing # while reading the file from application server

    Hi
    I am reading a file from application server. While reading into internal table with read statement the last field in each record is filling with hash symbol in the last digit. If I write any if condition with HASH symbol its not going inside the if condition, means its not recognizing as hash may be its internally treating as some other. I need to remove the hash from that field. How I can do that.
    Thanks,
    kishore

    I faced exact situation. Yes, internally its treated as some other special character. What i did was, becuase hash symbol was always coming at the end...i created a dummy field in my internal table so that it will not interfere with my actual data. When i see the data in my internal table, the hash always falls in the last field (dummy) which i will ignore. I could not get solution to remove this hash so i adopted this approach and it worked!!
    Hope it helps,

  • Reading .jpeg files in FILE or FTP adapter

    Hii
    I have to send .jpeg files at regular intervals using BPEL.
    I read about Base64 data type. I tried to create File Adapter and FTP adapter. I specified the folder location and *.jpeg as file pattern. I have made schema to opaque.
    But neither File or FTP adatper are picking up the file from specified directory. As per my plan, once I will get Opaque schema in BPEL, I will use Base64 encoding to get the data as string and to pass it to the endpoints.
    Any idea what I need to do in order to read .jpeg files.
    Any help is highly appreciated.

    Thanks for the help. Actually, I am following the similar process as given in "Tutorial 11 : File DB Integrations – Handling of opaque data types".
    I'm using SOA Suite 10.1.3.3; the .jpeg file is being picked up by the File Adapter, but failing to create BPEL instance with the following log details :

  • How do I get CS5 Bridge/Photoshp to handle RAW files from my D800E?

    How do I get CS5 Bridge/Photoshop to handle RAW files from my D~800E?

    There are many who would say, based only on empiric data (boo) and not opinion (yay), that the most accurate raw conversions would be obtained using the Nikon software and not secondary processors like the Adobe converter. The DNG process makes irreversible changes to the raw data which may or may not matter but the DNG is not the same as the original raw file.
    You can do the experiment yourself, for FREE, and compare different methods of raw conversion. You may be surprised at what you see. You have to be because different converters tune to different image characteristics. Don't be taken in about claims Adobe makes for its convertor without proving them to yourself. Adobe has made deliberate pre-set choices for its converter and they may not be the best for you. Or they may be, as we have all become so used to what Adobe chooses we think we chose it ourselves.
    If I were able to afford, and had the energy to lug around a D800e, I might not want to compromise the image quality I just shelled out such massive bucks to obtain using the Adobe converter without proving that was the best option for me, but I don't do it for a living. Also, if you can shell out for a D800e and are enamored of the Adobe Converter realize it only costs $10/month for a CC subscription, possibly tax deductible, and you can still retain your older version of PS. The CC version of PS allows use of the ACR as a filter layer, if you are fond of the converter tools (which are much improved in the latest version).
