    Re: how is a sis file implemented...

    The SIS file is an installation kit, just like *.msi on a Windows PC. Inside it there are several EXE and DLL files and many other files needed by an application. On Symbian you cannot transfer installed files (EXE and DLLs) aside from the case when the apps are installed on a SD card and the same card (not a copy) is inserted in a second device. Even in such case the applications may actively detect the change and refuse to work on the new phone so your only choice is to install the app from a valid SIS file.

    To learn more study the SDKs and docs provided by Forum Nokia

    Sir thankyou very much how does a GIF file work??? Its a series of images that are displayed... But where does the code lie that makes the image sequence work?? plus in series 60 would it be using API's to display new images or a win32 GIF file could work on a symbian phone??

    There are static GIFs (format version 87a, one image only) and animated ones (format version 89a). The GIF is however a data file, there is no code inside it and therefore it does not matter in which platform it is rendered. All that is needed is a GIF decode on the platform wich will read the info from the file and render the content accordingly. You will access these devoders through platform specific APIs.
