Code unique appl and icon for multiple operating systems?

All,

I'm new to the BB appl development.  I was finding this forum very useful, although I have some fundamental questions for which I can't find existing threads...

We need to create basically just a web app launcher (possibly with the overview icon) to get out by using BES.  We have a range of features and versions of OS (from 4.1) in support.  My questions have to do with how support these different devices and OS versions.  I hope I can have one application to get out for all devices instead of having separate applications to push to the respective devices based on the device or operating system.

So my current thinking is to compile the application targeting the OS 4.1, so will it work on that and all the new versions of the OS.  As far as I can tell (not having completely tested) the same code (to launch the browser and the overview icon support) for OS 4.1 is compatible up to all new OS versions. This approach, compilation on OS 4.1 only, seems reasonable?

My second concern relates to the icons that different devices prefer icons of different sizes.  What's usually managed?  Generally include you all files of icons of different sizes in the construction and through the code click on the appropriate icon based on detected device?  Or do you usually come out with a file of unique icon with dimensions that have air pretty much ok in all devices?  Some compromise between the two?

Thank you.

Code of Blackberry is compatible before not retro-compatible. So, if you are developing an application with older JDE it can run on the new OS, but not the reverse.

Also see this article:

http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800738/800901/What_Is...

And on the icon I don't think that any device have a preference of dimension.

You can use any reasonable size (ex: 50 * 50) for icon which will look almost the same in all devices.

  • It is not uncommon for me to have a half dozen + copies of a single image. I create these extra images that appear spontaneously myself this system should be obliging. I have 12 items and the Windows 7 operating system.

    I have 12 items and the Windows 7 operating system. It is not uncommon for me to have a half dozen + copies of a single image. I'm not creating these additional images myself, so must be the system. Deletion (including from the HDD) do not help. Can anyone help please?

    1. the only way to image files be automatically added to the catalog is to enable the option "watch folders" in the file menu and choosing not to have the Organizer warn you of any additions. If these files are already in the catalog they should be ignored, only new files should be added.

    2. otherwise, there is a downloader option to ignore duplicates when you import from card reader or the camera to avoid importing several times the same card.

    The organiser considers that the files are duplicated when they have the same "date taken" and the size in KB.

  • How to install multiple operating systems

    Hi, im from the India,
    I have hp Pavilion-15-N209TX, with Windows built-in 8.1,
    I want to install anothere os (Windows 7),
    Windows 8.1 Windows 7 plus several operating systems.

    How to do this?

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    The screenshots below is from a laptop HP 15 t-j100... options and the configuration on your computer screens may differ.

    You will need to DISABLE "Secure Boot" and ENABLE "Legacy Support" in the "Configuration of the BIOS start-up secure" on the settings page similar to what is shown below, until you try to install Windows 7.

    After you save the changes, the computer will ask you to confirm the changes... Accept the changes by typing the four digit code and press the ENTER"" key.

    If you install from a USB key and see a message of "load a driver - a required CD/DVD drive device is missing", it's because as 'System Configuration' > 'Config USB3.0 in pre-start' is set to 'Enabled '. This should be set to 'Auto '.

    In addition, as the hard drive is partitioned as TPG, you must start using the internal CD/DVD UEFI or UEFI-Key/key USB to install Windows on a GPT-partitioned disk. Turn on or restart the computer and press "F9" or "ESC", then "F9" when prompted. Select the source of boot UEFI you use and you press "ENTER".

    I suggest using Windows 7 SP1 for the best installation experience. If you need Windows SP1, see 'How to install Windows 7 without the disc' to download and create your own disc of Windows 7 SP1. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please download the Windows 7 USB/DVD download tool to create a Windows 7 SP1 USB Flash drive. Please note that some computers may not recognize a valid active UEFI USB Flash drive if it is formatted in NTFS and may require only a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installeror WiNToBootic. I like Rufus, because it contains options for 'Plan of GPT partition for UEFI computer' and 'FAT32'.

    From the top...

    (1) in Windows 8 / 8.1, reduce the "C:" partition and create a new partition of the unused space. Please see partitioning and naming of readers (Windows 8) for more information on partition in Windows 8 / 8.1.

    (2) download f6flpy-x 64.zip, extract the files/folders and place it on a USB Flash drive.

    (3) turn on the computer and immediately start typing the key "ESC".

    (4) when the MENU is displayed, press "F10".

    5) navigate the BIOS to the "System Configuration", 'USB 3.0 pré-OS Config' and the value 'Auto '.

    6) navigate the BIOS to the "System Configuration", "Startup Options" and "Secure Boot" the value 'Legacy Support' the value "Enabled" and "Disabled"

    7) press "F10" and click "YES" to "Exit Saving Changes".

    (8) computer should restart and display "Change of operating system startup Mode"... type the four digit code, then press "ENTER".

    (9) let Windows 8 boot to the top and put the Windows 7 SP1media in the drive to DVD or a USB port, then logout / stop.

    (10) turn on the computer and immediately start typing the key "ESC".

    (11) when the MENU is displayed, press the key "F9" and then select the correct boot UEFI source (CD/DVD drive internal, USB drive, CD/DVD, USB Flash drive, etc.). ... Press any key to start the CD/DVD, if prompted.

    (12) select 'Language', ' time / currency ' and 'Keyboard' settings and then click "Next".

    13) click on 'install now '... Check "Accept terms" and click "next". Click on "Custom (Advanced)".

    (14) you may need to provide Intel SATA/RAID drivers at the moment...  Use the Intel SATA/RAID drivers that you previously placed on a USB Flash drive.

    (15) to follow all instructions and meet the need. Enter the Windows 7 key when asked.

    Most of the 64 - bit drivers Windows 7 for HP ENVY 15 t-j100 CTO Notebook PC drivers of Quad Edition page should work on your computer. DO NOT use any BIOS or download of the firmware from this page. Please message the Windows Device Manager (text only) "Hardware ID" of all remaining missing or unknown devices, as shown in the example below.

    If you have any other questions, feel free to ask.

  • How can I get rid of windows 7 without deleting it and istalling a different operating system?

    How can I get rid of windows 7 without deleting it and istalling a different operating system?  I remember on xp, I couldn't allow him to function as a windows 95 or 98, if I wanted to.  I just want my computer works like windows xp.

    So can YER a little confused you explain a little better please.

    OR

    do you mean get W7 to resemble the way XP worked?

    In this case (start base fast and simple):

    • try to set a theme for a basic/classic theme - more like 98 then XP well.
    • Download (AV Control) and then use "classic shell" - menu style old XP.
    • Ditto for "explore classic" mentioned on this site.
    • Set the control panel to use the icons (small or large) as opposed to categories.

    But its still W7 in disguise.

    Is that the sort of thing you mean?

    If so, personally, I think its better to stick with W7 and get used to. I bet you will love windows 8 :)

    Can it be done? Guidelines to give me?
    Thank you
    Pete

    Hello

    in general there is no problem to install Windows 98 SE on a second partition on your hard drive. But you will have problems to find the drivers for this operating system, because it is not supported by Toshiba for this model. You must also bring.

    Good luck!!

  • T610 with Windows Embedded 7 - the system does not license for the operating system image

    Hello community,

    I bought a refurbished computer ThinClient T610 that is running a Windows 7 Embedded English. The label on the package says, that the computer ThinClient is allowed with W7E. When I now run Easy Tools installed on the computer ThinClient hp to create a USB Image with the German language, everything works fine: the image is downloaded from the web and put on the stick.

    But after you start the stick, the installation program tells me: "the system does not license for the operating system image. What I am doing wrong? The BIOS is already the latest.

    Or y at - it another way to transform the operating system in German? There should be an option to download additional languages, but this particual window has no other options. And I have not found any manual way to download other languages.

    Concerning

    Michael

    Sometimes it can be so easy... ;-)

    So here's my solution:

    1. go on the Web for hp Support site

    2. go in the software and driver download

    3. set the language of driver on the language of your choice (in fact: it was the main problem)

    4. download an operating system image

    5. run the configuration tool and copy the image of an operating system on a flash drive

    6. restart the workstation and install the os

    7. take advantage of your computer ThinClient in the language of your choice

    I don't know, why the hp Easy Tools downloaded the image of evil, but with this solution, that I find myself at the same point, as if they did.

  • When installing a new operating system isn't automatically wipe the hard disk, create a new partition, and then install the operating system?

    Have a Dell system, caught a virus and it has really messed up the PC. Recently, it got worse so I tried to reinstall the operating system with the Dell disks. It wouldn't work. So I bought for Windows 7 Professional, it will not be installed. My first question when installing a new operating system isn't automatically wipe the hard disk, create a new partition, and then install the operating system? Because this does the same as the Dell disks, is to take what is on the hard drive and put it in a folder called windows old, is not formatting the HD. When I boot the disk, it shows the installation of files then open windows and start the installation. Before he could finish I get an error missing or corrupted files. Tried several times now, windows will still not open. Any suggestions? Once while trying to install the pc crashed with a blue screen which is one of the reasons why I have reinstall the OS, he started to plant a few times. I don't remember all the details on my PC, but its 4 years, triple core coprocessors, ram 8 GB, 500 GB HD. At the same time just after all this started in Jan. I had also improved my 3 GB to 8 GB memory. I bought the Dell memory for my system. Since the crash, could there be a problem with these new memory chips? Last night I tried to disassemble each and reinstalling it, but that doesn't seem to make a difference. Before I tried to reinstall the operating system, the pc was see the concert 8.

    First run Memtest86 +:
