  • Can any help me with Calendar

    I am making sort of calendar. I'm new with this class.
    How can I get name of the day on witch month starts. (Exemple 1 June, which day is it, monday, thursdy...).
    If any has a tutorial about calendar or something to help me please tell me.
    Thanks very much!

    javadocs?
    DAY_OF_WEEK_IN_MONTH
    public static final int DAY_OF_WEEK_IN_MONTH
    Field number for get and set indicating the ordinal number of the day of the week within the current month. Together with the DAY_OF_WEEK field, this uniquely specifies a day within a month. Unlike WEEK_OF_MONTH and WEEK_OF_YEAR, this field's value does not depend on getFirstDayOfWeek() or getMinimalDaysInFirstWeek(). DAY_OF_MONTH 1 through 7 always correspond to DAY_OF_WEEK_IN_MONTH 1; 8 through 14 correspond to DAY_OF_WEEK_IN_MONTH 2, and so on. DAY_OF_WEEK_IN_MONTH 0 indicates the week before DAY_OF_WEEK_IN_MONTH 1. Negative values count back from the end of the month, so the last Sunday of a month is specified as DAY_OF_WEEK = SUNDAY, DAY_OF_WEEK_IN_MONTH = -1. Because negative values count backward they will usually be aligned differently within the month than positive values. For example, if a month has 31 days, DAY_OF_WEEK_IN_MONTH -1 will overlap DAY_OF_WEEK_IN_MONTH 5 and the end of 4.

    If the amount of the purchase is close to $21.07, then you need to take into account taxes may be added.

  • I'm having trouble with the volume of my i phone 4s when using headphones, the sound will only appear when the volume is at its highest, any lower and all I hear is static. Can anyone help me with this problem? Much appreciated.

    Hi, I'm using a white iPhone 4s with 16gb memory and having some problems. Whenever I use earphones the sound will be heated when the volume is at the highest if I turn it down any lower all I hear is static. Can anyone help me with this problem as I would appreciate it much.

    Reset the device:
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    If that doesn't help, tap Settings > General > Reset > Reset All Settings
    No data is lost due to a reset.

    Thank you

    CC is for retail use with 20 GB of storage space, CCT is where number of seats are purchased & assigned by one program admin where each seat gets 100GB of storage space.
    You can not have both the CC & team in one account as it will only provide you added storage space of 120 GB but you can activate the CC any of them or either of them twice as CC is based on Adobe ID.

    I was playing with this a little bit and came up with this game model, something that I'm sure can be improved upon greatly:
    TttXO.java
    an enum to encapsulate X vs O. I could use a boolean here since it has 2 states, but this seems more intuitive to me
    package dy08.m05.ttt;
    * tic tac toe encapsulation of X vs O

    public enum TttXO
        X, O

    encapsulates an individual cell in the tictactoe grid.

         * @param TttXO
         * @return true if successful, false if already occupied
        public boolean setXO(TttXO xo)

  • Can anyone help me with a problem i am having with my music on my iPhone 4S. I have put alot of Compilation CDs in my library on iTunes. I download these tracks onto my phone, everything is ok so far. Now, this is what is niggling me and I don.t know how

    Can anyone help me with a problem i am having with my music on my iPhone 4S. I have put alot of Compilation CDs in my library on iTunes. I download these tracks onto my phone, everything is ok so far. Now, this is what is niggling me and I don.t know how to resolve it. This is my problem: 
    Have downloaded for example: Queen – Bohemium Rhapsody from a compilation album as well as a few complete Queen Album CDs into the iTunes library and then put them into playlists,
    When I go onto my phone and select Queen on the MUSIC app using Songs tab at the bottom of the screen it will display all Queen songs and their resective Alum pics, that is all those not in a complilation album, .
    If I know the song title I can select the songs tab and find the song that way,
    I’ve tried fiddling with the settings in the iTunes app by going to ‘get info’ tab and trying to sort the problem out that way but am not having much luck.What I want the phone to do is show, for example all Queens songs including those in compilation albums. Can this be done, would be grateful for any ideas on how it can be done, that is if ic can be done, any ideas
    Thanks for your help

    Try assigning Queen as the Album Artist on the compilations in iTunes on your computer.

  • Can somebody help me with this code?

    Can anyone help me with this code? My problem is that i can't
    seem to position this form, i want to be able to center it
    vertically & horizontally in a div either using CSS or any
    other means.

    </div><!-- End Search Bar -->
    Pleasssssseeeeeeee Help
    Thanks

    Hi,
    Your form is defined in a div named "serchcartcont", you can
    use attributes like position and align of the div to do what you
    want to do. But there are two more dives above this dive, you will
    have define the height width of these before you can center align
    the inner most div. If you are not defining the height & width
    then by default it decide it automatically to just fit the content
    in it.
    Hope this helps.

    Is the TV at minimum a 1080p with an HDMI port?
    What is your Machine ID?  DO NOT give us your serial number.  We just need the x and y values of the Machine ID in your system profiler as given in this format:
    MacBook Pro x,y
    This will tell us what display cables can connect to your TV.

  • Can anyone help me with how to install itunes on windows 8.  The apple techs suggestions did not work

    Can anyone help me with how to install itunes on windows 8.  The apple techs suggestions didn't work.  Spent most of today installing and uninstalling itunes according to their instructions.  They will charge me again if I call again.

    When I run the iTunes64setup.exe it says: "The thingy is not a valid win32 application."
    That generally indicates that the installer has been getting damaged on the download.
    What web browser have you been using for downloading the iTunes64Setup.exe? Does it make any difference if you use Firefox instead of IE for the download (or vice versa)?

    I've tried over and over to download Creative MediaSource through the Windows Vista application section for the Zen Touch. It continuosly gives me this error during file extracting. Can anyone help me with this?!

    Hi 
       I have checked to see if there are any Windows 8-8.1 drivers available for your model machine from HP and sadly none are listed , Also even if it had been possible to get driver support for the upgrade you would have still had to pay Microsoft for the upgrade via Retail disk package or an online ISO download .
