    Loading or Updating the images slowly during the parsing process of xml ..


    I have built a application for( symbian 3 phones) which lists out the channel images list using the xml parsing process.


    But when I run the application ,It takes very much time to laod the images and every time I run the application, the laoding starts freshly without creating any

    local database or cache for storing the data.


    I want to eliminate this problem. Please help me by guidining How to overcome this issue/problem.

    maybe you could make a local database, as well as instead of using compressed image formats, you could try saving the images in mbm format, then the processing would be a lot faster.

    Loading images takes time. Depending on what you need to do with them, it may be possible to load them only when they are really going to be displayed.

    My application parses the images and data like channel images and channel names contained in the xml.aspx file . Actually my application is live streaming application which displays the images

    first then when clicked on the images ,plays the live stream or video. So I want to avoid too much waiting time for the users as " laoding images is taking much time"

    I have already added the code as below

    _LIT( KMYSEARCH_mbmFile, "\\resource\\apps\\MyView_mbm.mbm" );

    basically it is your own application, thus you would need to design and implement the logic by-your-self. Anyway, you could try the ideas as suggested here, thus check what was suggested, see how you can utilize the suggestions, and then if you have problems implementing the suggestions, then please ask again.

    Basically, you can not expect all parts to be delivered to your without you actually doing something in there as well.

    I have added the code like
    ..\data\Assets\etnow.png C:\system\Apps\Assets\etnow.png
    ..\data\Assets\newx.png C:\system\Apps\Assets\newsx.png
    ..\data\Assets\timesnow.png C:\system\Apps\Assets\timesnow.png in both bld.inf and .pkg files.

    What should I write in .cpp to access the images

    You could speed up your development if you would search a bit, basically if you want to access images thata re not mbm or mif files, then you need to use image decoders. For examples, please do search our wiki.

    Check API docs for the CFbsBitmap, basically use the Save function to same each image to individual mbm file.

    Wiki also appears to have article on making multi-bitmap mbm files: http://www.developer.nokia.com/Commu...on_of_MBM_file

    In Symbian C++ environment you usually provide fully qualified filenames, e.g. filenames with drive letter and path. If you are really interested if there is a "current" location when saving, you could save something in the emulator, and locate the file in the file system from Windows.
