How to get weather updates

How can my java program get weather forecasts/severe weather updates from the internet?

use thread or timer task (which in turn use thread) to connect to the url (may be RSS feed) that have the weather information. (use URL, URLConnection class . Read the inputstream. make a string out of it . The string will be most probably a xml so transform the string into xml. then use xpath to retrieve the value (ex temperature) from the string).

    Hello THEVIN7
    The next step if it is not updating, would be to delete the app and then download it again. Check out the general troubleshooting for apps purchased form the App Store.

    Oh no! I'm sorry to see there's a lot of confusion here and data shared, x-rayDon. We can definitely work to fix. This happens when two devices share the same Apple ID, so she will need to reset hers. She can do so by assessing this link Apple - My Apple ID. You will need to decide who will keep the account if want separate Apple IDs since purchases cannot be shared unless you do Family Sharing.

    You could go hunting for a fair price on a refurbished or restored Intel-based Mac or MacBook, as most early models of CoreDuo and Core2Duo can run Snow Leopard 10.6.8, and some much more recent.
    The Apple Store's Special Deals section that is online has some fairly recent examples of hardware with an OS, original accessories as noted, power cord, and complementary one year coverage. Eligibility for extended AppleCare plans are noted & may be available for various items in the store. Subject to availability. Refurbished. Like new. The price difference can be about the same as the additional two year AppleCare plan may cost, so get that too.
    Third party repaired restored or available through other channels vary in quality, quantity, condition, and may be lacking in some or most original accessories; they should include basic hardware as originally equipped and have the boot-install software disc set as intended for that build model & year specification, included.
    Auction sites rarely have that much of a kit together, w/ missing discs, scruffy, extra fees, etc. On the other hand, companies that restore and repair Macs for a living and are authorized Apple service centers may have something, if you aren't in the market for something holiday new or really quick. Older models if reasonably refurbished can still shine years later.
    Hopefully this helps somewhat.
    Good luck & happy computing!

  • How to get an updatable ADODB Recordset from a Stored Procedure?

    In VB6 I have this code to get a disconnected ADODB Recordset from a Oracle 9i database (the Oracle Client is 10g):
    Dim conSQL As ADODB.Connection
    Dim comSQL As ADODB.Command
    Dim recSQL As ADODB.Recordset
    Set conSQL = New ADODB.Connection
    With conSQL
    .ConnectionString = "Provider=OraOLEDB.Oracle;Password=<pwd>;Persist Security Info=True;User ID=<uid>;Data Source=<dsn>"

    .CommandText = "P_PARAM.GETALLPARAM"
    .Properties("PLSQLRSet").Value = True
    End With

    .CursorLocation = adUseClient
    .CursorType = adOpenStatic
    .LockType = adLockBatchOptimistic
    .Open
    .ActiveConnection = Nothing
    End With
    The PL/SQL Procedure is returning a REF CURSOR like this:

    IS
    BEGIN
    OPEN op_PARAMRecCur FOR
    SELECT *
    FROM PARAM
    ORDER BY ANNPARAM DESC;
    END GetAllParam;
    When I try to update some values in the ADODB Recordset (still disconnected), I get the following error:
    Err.Description: Multiple-step operation generated errors. Check each status value.
    Err.Number: -2147217887 (80040E21)
    Err.Source: Microsoft Cursor Engine
    The following properties on the Command object doesn't change anything:
    .Properties("IRowsetChange") = True
    .Properties("Updatability") = 7

    4 years later...
    I was having then same problem.
    Finally, I've found how to "touch" the requierd bits.
    Obviously, it's hardcore, but since some stupid at microsoft cannot understand the use of a disconnected recordset in the real world, there is no other choice.

  • How to get kitkat update

    how to get the kitkat update for the note 3

    ALL other US Carriers already have KIT KAT on the Galaxy S4!!!  Verizon does NOT, That is a fact!!
    Now we know Verizon's intention.  NO Kit Kat for GS4's any time soon!!  When you look at Verizon's promotion of the GS5 it talks about how great KIT KAT is and how the GS4 DOES NOT HAVE IT, which means it is not coming any time soon!!!!
    <<From Verizonwireless.com>>
    The operating system
    All three smartphones run the Android™ operating system, but different versions. The S III and the S 4 have Jelly Bean, while the S 5 has KitKat 4.4.2.
    KitKat employs the latest technology to deliver crisp visuals and a seamless, more immersive experience for you. Launch voice commands with two words, “OK, Google”, and read more easily with immersive mode. The status and notification bars disappear when you’re in certain full-screen apps or games, but, don’t worry, you can bring them back with just a swipe of your finger. Plus, KitKat is the most efficient Android operating system yet, using less power overall while running the same apps and programs.
    Verizon GS4 Customers - All other US carriers have given their customers with GS4's (and who pay less for their service)  "the latest technology" (as stated above).  But us Verizon Customers are left WITHOUT THE LATEST TECHNOLOGY on our "flagship phones"
    FIX IT VERIZON!!!!!!!!!!!!!!!!!!!!

    8GB ram

    Windows HP SP1 with all updates installed at this time.
    How can I get automatic updates for this machine and operating system and if so, how do I get signed up for those?
    Should I just choose a model number and pretend it is the model I have? Which number should I choose?

    All computers in the same part-number family (PSAY3U) are essentially the same. The drivers and utilities for this one should work.

  • How to get idvd updates

    I have idvd 4.0.1 and want to update the latest version, but can't figure out how to get it.
    Any ideas??

    If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like Amazon.com: ilife 09: Software or eBay.com.  Why, because iDVD (and iWeb) was discontinued by Apple over a year ago.
    Why iLife 09 instead of 11?
    If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides  themes from iDVD 5-7.  The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them. 
    Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
    This shows the iDVD contents in the iLife 09 disc via Pacifist:
    You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.
    Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar.  Select Size = Medium or Large.
    Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
    Follow this workflow to help assure the best qualty video DVD:
    Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image  menu option. This will separate the encoding process from the burn process. 
    To check the encoding mount the disk image, launch DVD Player and play it.  If it plays OK with DVD Player the encoding is good.
    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

  • How to get the update file without using Nokia Sof...

    The network connection is unreliable and downloading the firmware update using PC Suite for my Nokia E90 proves difficult. Does anyone know how I can get the firmware version 300.34.84?
    The trouble is Nokia's Software Updater does not accommodate any slight interruption to the connection during the update process. I will update this discussion with what version of PC Suite I have once I get that info.
    Any help is kindly appreciated

    In fact, it is not Possible to get the update file without using Nokia Software Updater or you should search the net to find the update files in another place and even you get them, you can not use them with NSU.
    You can Update your Device with:
    1 - NSU (Nokia Software Update)
    2 - FOTA (Firmware Over The Air) for FP2 devices ONLY.
    3 - Nokia Care Center
    there is not other way to upgrade.
    Hope useful for u.

  • How to get only updated records for a column using loading type INSERT

    Hi,
    Good morning all,
    I have source1 containg 3 columns bill_cd,bill_desc,bill_date and
    source2 has the columns bill_cd,bill_key,source_id.
    My target has the columns bill_cd,bill_date,bill_desc .
    Now the requirement is, bill_cd in target should not repeated when we run the mapping more than one thime. it should get only updated records not the previous records using only INSERT Loading type(for target) not to use update/insert.
    How can we achieve this logic in mapping level.
    Anybody Please give me some solution immediately.
    Thanks in Advance,
    Siv

    Thanks Herzog for your reply,
    Here bill_cd is not unique. Yes,I want only new records using INSERT as loading type. Suppose when the map runs for the first time, bill_cd is loaded with values 1 to 5.
    Now, in the source I have got new records 6 to 10 for bill_cd and when I run the mapping again I need to get only records for bill_cd from 6 to 10 using INSERT as loading type.
    Is it possible to achieve this at mapping level?
    Regards,
    Siv.

  • Applied SOA patches (server), how to get patches/updates into JDeveloper?

    Hi
    We have recently applied the 10.1.3.3.1 MLR5 patch to our SOA Suite installs. In this there is a bug 5883401 listed as being resolved by the patchset.
    We have logged an SR to find out the details of the bug (as it is once again not visible to us mere customers paying good money for support).
    From this it became clear that the fix for this bug is really a JDeveloper (XSL Mapper) fix.
    Oracle Support has so far been unable to help us with the information on how to get this fix (or any other fix) applied to JDeveloper. (we are using JDeveloper 10.1.3.3.0 build 4157)
    Can anybody in this forum please shed any light onto this matter?
    How do we get this fix or any other fixes applied to JDeveloper?
    Your help and inputs are much appreciated.
