    First off, from http://www.catb.org/~esr/faqs/smart-questions.html
    h1. How To Ask Questions The Smart Way:
    h3. Write in clear, grammatical, correctly-spelled language
    More generally, if you write like a semi-literate boob you will very likely be ignored. So don't use instant-messaging
    shortcuts. Spelling "you" as "u" makes you look like a semi-literate boob to save two entire keystrokes. Worse: writing like
    a l33t script kiddie hax0r is the absolute kiss of death and guarantees you will receive nothing but stony silence (or, at best,
    a heaping helping of scorn and sarcasm) in return.
    Next, use a SimpleDateFormat object. You can use it directly or use a date format string to tell it how you want your date string formatted. The API will give you lots of information on how to use this. Note that you'll have to translate the Calendar object to a date object via the getTime() method:
        class ButtonHandler implements ActionListener
            public void actionPerformed(ActionEvent evt)
                Calendar rightNow = Calendar.getInstance();
                //** use SimpleDateFormat
                SimpleDateFormat dateFormat = new SimpleDateFormat();
                String dateString = dateFormat.format(rightNow.getTime());
                if (evt.getSource() == btnLogin)
                    String login = tf1.getText();
                    String password = tf2.getText();
                    JOptionPane.showMessageDialog(mainFrame, "Student ID " + login
                            + " Login at " + dateString,
                            "Response",
                            JOptionPane.PLAIN_MESSAGE);
                if (evt.getSource() == btnClear)
                    tf1.setText("");
                    tf2.setText("");
        }Finally, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, either use the "code" button at the top of the forum Message editor or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
    [code]
      // your code block goes here.
    [/code]

    need help with how to reset bios and admin password to reformat hard drive in 8440p elitebook? removal of cmos, resetting laptop, using cccleaner, windows password recovery and hiren's was noneffective, any help is appreciated. thanks

    Hi,
    As your notebook is a business class machine, security is more stringent - the password is stored in non-volatile memory and there are no 'backdoor' passwords.  Your best option would be to contact HP regarding this.

  • Hi! I accidentally deleted my app store from the phone....how to retrieve it back...pls help me...just using the iphone

    Hi everyone
    I am a new user of iphone 4...i've accidentally deleted the app store from the iphone...pls tell me how to retrieve it back...pls help...tq

    To restore the missing App Store Icon, or other original Apple Icons on the iPhone, go to Settings / General / Reset (Don't worry, you will be presented with a number of options concerning resetting before anything happens. The iPhone will NOT reset just by selecting this option).
    Choose "Reset Home Screen Layout". This will restore the App Store Icon as well as other Apple Icons you may have removed or placed into folders.
    Please note. This also removes any folders you have set up and rearranges all of the apps you have, so it takes awhile to put everything back where it was.
    Unfortunately, I did not capture the placement of my Icons, so I had to recreate from memory...not that big a deal. If you elect to follow this procedure, make a note of where all of your icons are placed and then proceed.
    I followed links that talked about restoring through iTunes...never could make anything like that work. This is a quick and simple fix.

    Hi newyorker2014,
    I apologize, I'm a bit unclear on the exact nature of your issue. If you are no longer seeing the app in question on your iPhone, but it is showing as purchased on the App Store, you should be able to redownload it directly. You may find the following article helpful:

  • How to reset table in Status "Replicate - Error'?

    Hi,
    we have a HANA sidecar scenario (HANA revision 82) where we replicate tables from ECC non-HANA towards HANA with SLT for operational reporting (using DMIS_2011_1_731 SP7).
    In total we have about 550 tables that are being replicated fine. There are however 2 tables that went into status "Replicate - Error": for instance table KONV. There are other large tables that replicate fine. When I have a look at the transaction LTRC, I find the following message:
    - Error while generating runtime objects for Z_KONV_002
    - Syntax error in function module /1CADMC/ACS_00100000000240
    - Error message: Method "ADJUST_INTERVAL_LOWER_BOUNDARY" is unknown or private or protected
    In attempt to solve this, we will load SAP notes 2041240 + 2016512 and test again.
    But how can we reset a single table as if it has not been selected for replication before? Is this via a specific expert function in transaction LTRC and a physical deletion in RS-tables on HANA? This is needed to be able to start replication again for that single table, right?
    Thanks in advance!
    Stijn

    Hi,
    I'm assuming that you want to reload table KONV completely into HANA? Through transaction LTRC, once in the required mass transfer ID/Configuration, on the Table Overview Tab, press the Data Provisioning button and then enter the table name in the appropriate field. Select the 'Stop Load/Replication' option and execute (make sure the master job is running).
    This will remove the triggers/logging tables in ECC and set the appropriate status for the table in HANA. You can check progress on the Table Overview tab...once KONV disappears, press the use the Data Provisioning button again and change the option to 'Start Replication' for KONV and execute. This will drop the data in HANA and then create the logging table and triggers again, then start the initial load phase and when the load is complete, the table should switch to 'replicate'.
    Word of caution, you might want to maintain any required performance options/filters before you reload.
    Hope this helps.
