FUhr: myFirstMIDlet - what is the most compatible configuration? request fo

Hello,
I have just programmed for the first time in java, and in j2me,
using sun's j2se and j2me. On my own phone, nokia 6230, the
midlet works well. Also in the sun- and nokia6230-emulator.
But a friend with a slightly older Nokia phone couldn't get
it working. Some "not supported" error message.
Please have a look at the following JAR, it's really really
small (<4kB), so cheap to download to your phone.
It's very interesting for me, on which phones which version works:
http://www.andreasK.de/fuhr/s01/fuhr.jar JTWI MIDP2.0 CLDC1.0
http://www.andreasK.de/fuhr/s02/fuhr.jar JTWI MIDP2.0 CLDC1.1
http://www.andreasK.de/fuhr/s03/fuhr.jar MIDP1.0 CLDC1.0
http://www.andreasK.de/fuhr/s04/fuhr.jar MIDP1.0 CLDC1.1
Thanks a lot, already in advance!
Probably the most compatible is s03, isn't it?
Do many phones use that?
What do you think about the program? Please tell me your opinion.
It's for a festival, the probably best place on earth
next weekend: www.fusion-festival.de
Back to my program. The most urgent improvements are:
* a continuous update whenever a new "real" minute begins
- any hints how to do that? Timer? Events?
* a key-lock feature so that the programm can continue
to run while the phone is in the pocket.
Can I "overload" the standard keypress-routine?
How to?
* a bigger fJahr:1887 display.
It's already the biggest font size, and changing the font
seems to work only with MIDP2.0.
Any hints how to draw a bigger 4-digits-number,
perhaps even in MIDP1.0?
* automatically recalculate whenever one of the datetime fields
has been changed by the user. how to?
thanks a lot!
Andreas

Heho,
There is a newer version now, without any double variable.
I hope that solves the "floatingpoint not supported" problem.
Please try now:
http://www.andreasK.de/fuhr/s04/fuhr.jar (v1.6)
or http://www.andreasK.de/fuhr.jar (v1.6)
Thanks a lot, already in advance!
Probably the most compatible setting is (MIDP1.0 CLDC1.0), isn't it?

  • What is the most compatible HD Hard Disk camcorder with a mac?

    I'm looking to purchase a new High Def, Hard Disk camcorder, but I'm unsure what will be compatible with my Mac? I've read on this messageboard that tons of people have trouble getting these hard disk camcorders to sync with their Macs. I want to buy a Sony, but it seems that they are not very Mac friendly. THANKS!

    It's not really an easy question for me to answer, I've gone from a pro DV camera to a consumer HD camera and in many ways I'm a little disappointed, but the comparison is hardly fair.
    My hobbies are video and motor sport, so my cameras get quite a challenge and on occasions the HD camera falls short. But as I say it connects well, I have no reason to believe I bought the wrong consumer camera, (just shouldn't have bought a consumer camera) and there are some pretty cool features such as the 100 fps option (except I can't get that stuff off the camera yet)

  • What is the most compatible automator webcam?

    I've tried a firewire DV camera that works in all other programs except automator. Does not have to be super high quality infact I need one as cheap as possible but which cameras are compatible?

    I have found the Motu MTPAVUSB to be very fast and dependable. unfortunately it does not support 23.976fps timecode because midi does not support 23.976fps. but it does support all the other frame rates.

  • I just downloaded Firefox 6.0. The web page asked if I wanted to upgrade. What is the most recent version of Firefox and why can't I get it denoted in the propperties link? Also why is it not compatible with AVG Tool Bar?

    I just downloaded Firefox 6.0. The web page asked if I wanted to upgrade. What is the most recent version of Firefox and why can't I get it denoted in the propperties link? Also why is it not compatible with AVG Tool Bar?

    Firefox 6.0 is the current version.
    Get what denoted in what properties link.
    You can get the version number in Help -> About Firefox,
    and in '''about:support''' typed into the Location bar, and you can use JavaScript to list the user agent -- javascript:navigator.userAgent
    I'm not aware of any version of Firefox from Fx 2 on up to Fx 6 where "AVG Safe" is not a problem. Crashes aren't the only failures caused.

  • What is the benefit of configuring the XSS Homepage Framework for ESS

    What is the benefit of configuring the XSS Homepage Framework for ESS?
    Over using standard iViews.

    It means you can disable (or enable) the exact functionality your customer needs rather than sticking with the default implementation.
    Most customes do not use everything available from ESS or MSS.  Switching it off (making it unavailable) is WAY better than leaving potentially unconfigured content to be accessed by users.  SAP generally do not handle the error cases and you will get lots of nasty stack traces .....

  • What is the most recent update to iPhoto?  I have a note about 9.5 yet my macPro has 9.4.3 and says I am current.

    What is the most recent update to iPhoto?  I am transferring my library from a remote drive to my macPro, using iPhoto library manager, and get a message that the pictures I am transferring are in iPhoto 9.5.  My computer has 9.4.3 and it says my software is up to date.

    iPhoto 9.5.1 is the most recent iPhoto version. However, iPhoto 9.4.3 is the last iPhoto version for your OS X version. If you want to use iPhoto 9.5.1, you need to upgrade to OS X Mavericks. You can download it from the Mac App Store.

  • What is the most recent stable release of Oracle Coherence?

    What is the most recent stable release(or versions) of Oracle Coherence?

    We are using 3.5.1 with Patch1.
    You will need to download Patch1 from MetaLink (and hence need an OracleID).
    Continuous Queries don't work in 3.5.1 and there are a number of other small bugs.
    I understand there are a few problems with Coherence*Web in 3.5.1.p1 (but we aren't using that).
    Here's the patch1 list (its 2521 that was an issue for us) :
    Issue COH-2569: CacheFactory and CacheFactoryBuilder do not respect CacheFactory.setConfigurableCacheFactory()
    Issue COH-2568: CacheFactoryBuilder doesn't check the configurable-cache-factory-config element when the non-default URI is passed to getFactory
    Issue COH-2548: ClassNotFoundException can occur if multiple web applications are deployed when using application or EAR scoped cluster nodes
    Issue COH-2547: NPE in Daemon.isGuarded()
    Issue COH-2543: The optimistic locking mode does not reject updates to sessions that have been concurrently invalidated
    Issue COH-2524: Multiple DefaultConfigurableCacheFactory instances fail returning NamedCaches on the same service
    Issue COH-2521: CQC does does not propagate asynchronous events
    Issue COH-2515: ArrayIndexOutOfBoundsException in SafeSortedMap

  • What is the most sensible way to extend a wifi signal. I am in a cinderblock house and I have to buy something that will give me a single network but added range from my airport extreme base station.

    What is the most sensible way to extend a wifi signal. I am in a cinderblock house and I have to buy something that will give me a single network but added range from my airport extreme base station.

    Use an Airport Express. Configure the AEBS to allow it's wireless network to be extended. This is a dropdown menu option under the Wireless tab. Configure the Airport Express to Extend an Existing Network also under it's Wireless tab. You will need to provide the name of your network used in the AEBS as well as the network's access password.

  • Laptop editing with Premiere Pro CS4: what are the most important specs

    Laptop Editing: What are the MOST important specs?
    Hello everybody, I have been a long time lurker, but I decided to join in and share my voice.
    I've been editing, for a while now, various projects of various lenghts shot on my HV20, on an IMac using Adobe Premiere Pro. Actually, I bought the CS4 Extended Production Suite last year  thinking that it made sense to be able to edit, do the coloring and effects+ sound all within the same suite.
    AND, it came with OnLocation, wich is, I think, a fantastic tool. I really want to be able to record and monitor my future shoots using OnLocation. I've seen how useful monitors and scopes are on set, and the idea of being able to shoot in HD and actually checking the focus on something larger than a few inches is very appealling!
    So a laptop is in my future. Now, what are the most important specs?
    I could buy 1) a barely used Macbook pro early 08- 17" HD led display ,4g Ram ddr2 ,nvidia 8600M GT 512 VRAM ,800Mhz BUS, 200G 7200HD
    and have enough money left to buy an Apple Display 30" refurb
    OR 2) a new Macbook pro 17, 4 g Ram ddr3, 512 VRAm, 4g Ram ddr3, double procsessors 9400M+9600M GT 512 VRAM, 1066 BUS, 500G 7200HD
    and wait for a second display!
    Plus, of course, a portable External Scratch Drive on the Express Card. Now, if that fast drive is handling the footage, could'nt I settle for a 5400HD in the laptop,, they seem much less prone to problems-clicking noise, heat-than the 7200, especially in the new unibody model. Is 800 versus 1066 BUS a terrible trade-off? In terms of secondary displays , I've heard less than lukewarm things about the new Apple 24 LED (glossy is no-no for me).
    My intentions are to make documentaries and short fictions as well. I make a living as an actor so I don't need to be performing as a director/editor business wise!
    I do want to explore that side of the craft, in a professional and enjoyable way though. I know that, in addition to the laptop, I will get a MacPro in a few years.
    Thanks a lot for the inputs!

    Successful video editing (as compared to tear your hair out video editing) requires at least two hard drives... one for all software and one for all data... some people use 3 drives, with data on one and scratch files on the 3rd drive
    I'm not sure about software, but everything I've ever read in this forum says 5400 is NOT fast enough for the data drive
    If you want to edit video... you have to buy the hardware that works

    CPU, RAM, bus speed, system HD, external HD, graphics - basically in that order
    You should think in terms of purchasing for maximum future use. In that regard the new 17" MacBookPro is the way to go. The specs are significantly better than the early '08 MacBook and you will be much happier in the long run with performance, software support and longevity.
    If you really need a large display, consider a 24" Dell, HP, NEC, etc. in the $200-$300 price range to stay within your total budget. You will be pleasantly surprised how good they are.
    You could start out with the 5400rpm system HD - you can replace it anytime with a 7200rpm drive if necessary for hardly any more $ than it would cost in the first place; and replacing it does NOT void your warranty. But you WILL want/need a good external FW800 or eSATA drive (for eSATA you will need an eSATA expressCard/34 however) no matter what.
    One other thought, if your primary use will be with an external display, and you don't actually need eSATA capability (FW800 will do you just fine at this point), then the 15" 2.66GHz or 2.8GHz MacBookPro models will be just fine at a significantly lower cost than the 17" model.

  • What is the most efficient (in terms of cost) way to transfer 35 mm slides to my iMac hard drive?

    What is the most cost efficient way to transfer 35mm slide images to my iMac hard drive?

    This gives you the basics
    http://www.tech-faq.com/how-to-copy-slides-to-disk.htm
    The first option, the professional one, isn't the cheapest - but the results should be good.
    The second option is very appealing. Some printers come with brackets that can be used to scan film or slides.
    The third option is a slide scanner. I haven't used this option, but there's a significant startup cost of under $100.
    In short, a scanner is the cheapest and most efficient option.

  • What is the most RAM I can put in mac book pro 15 inch 2.16(2006)?

    What is the most RAM I can put in mac book pro 15 inch 2.16(2006)?

    Depends. There were two version of the MBP that shipped in 2006 with different max RAM. The quickest way to see which is yours is to use System Profiler to get your Mac's "Model Identifier."
    Do "About this Mac" from the Apple menu and, in the resulting window, click "More Info..." That launches System Profler for you.
    The answer is in the first screen of Profiler that comes up--"Hardware Overview." Note the second line in this example:
    If the Model Identifier says "MacBookPro1,X" you are limited to 2G RAM. Period.
    If the Model Identifier says "MacBookPro2,X" you can install two, 2G modules for an installed total of 4G RAM, but the logic board can only access 3.2G of it. That becomes your "max RAM.
    Hope this helps,
    AJ
