Deliver the fall down to the front screen, which relates

HI gurus... I have another question, the question is
I have the screen of the front end application where the default value for the field should be "ALL".
How ever its showing one of the values in the list of values (LOV).
The 'ALL' value is at the bottom of the drow downs where, as it should be at the top of the list of values (lov)
Now I'm confuesd if it is a problem of Java or the PLSQL question.
Plsql developer this number is assigned to me.
But do not know what to start with.
I spoke with my head and he says he must dig through the table of parameters and find the sql used by the screen.
But I'm just unsure of him.
Help, please...

This looks like a problem of sorting. What kind of select fills your LOV? If the 'ALL' value is added to a UNION ALL select operation, then you might need to add an order by clause.

example: create a LOV that shows some NLS_parameters and an option ALL to choose all the parameters at the same time.

/* ALL at the end */
select name param
from v$parameter where name like 'nls%'
UNION ALL
select 'ALL' param from dual;

PARAM
----------------
nls_language
nls_territory
nls_sort
nls_date_language
nls_date_format
nls_currency
nls_numeric_characters
nls_iso_currency
nls_calendar
nls_time_format
nls_timestamp_format
nls_time_tz_format
nls_timestamp_tz_format
nls_dual_currency
nls_comp
nls_length_semantics
nls_nchar_conv_excp
ALL

/* sorted list, ALL at the beginning */
select name param
from v$parameter where name like 'nls%'
UNION ALL
select 'ALL' param from dual
order by param;

PARAM
----------------
ALL
nls_calendar
nls_comp
nls_currency
nls_date_format
nls_date_language
nls_dual_currency
nls_iso_currency

    Sorry if this is a stupid question... you can keep the front screen unlocked? It's a pain to try to answer a call or even read a text without constantly having to unlock all the time... TIA Andrea

    There is an application called "No Lock".  It does not block the screen, hide but will all move together to the lock screen.  I really like this app.  I use it all the time.  I hope this helps.

    To the point where I have indicated the asterisk above, it has a slash which rotates in a circular motion.

    My thought is that it's either the Windows code is corrupted or is a hardware failure.  While I am not positive, I feel that it occurs when Internet Explorer is used.   System Restore is not enabled on this computer, so this isn't an option.  Can someone help me understand this means and how I could fix this?  I know that will later Windows version can solve it, but this isn't the answer I'm looking for.  Thank you

    Attempt to initialize the network is not a 'possible', it is certain that your PC is doing exactly this depending on your BIOS settings. In addition, she tries the network initialization after already trying to start on an optical disc. The two attempts at device boot doesn't have, in all likelihood after having already failed the boot from the hard drive. There is no message to indicate than an attempt to boot to the hard drive, or he leaves the screen too fast to see you or you did not save it in your original post.

    My advice on the diagnosis is based on the studied the real model of your PC, not generic advice for all Dell PC with Vista installed.

    1. Your computer has already finished POST (Power O n Self TEST) otherwise you wouldn't see any attempt to start at all.
    2. You've already provided specific error messages.
    3. I have already advised the best and most approriate diagnostics for your PC.
    4. Your PC will not start in any mode if it becomes a default 'hard', rather than the intermittent fault means your original message. Start in any mode, you can and make a backup as soon as possible.
    5. Unless these recent changes include adjustments to the BIOS settings, they are irrelevant, that he is a boot failure which can be caused by anything done under Vista.
    6. Removing the external devices is never a bad step of troubleshooting if you encounter problems. I doubt it will help in this instance, but it will not hurt to try, especially if they are peripheral bootable.
    7. Startup Repair will not solve a hardware problem (by far the most likley scenario).
    8. System Restore is not usable unless you can actually start to Vista and it's never going to treat problems of material.
    9. IMO, this is not a software issue. See also point 4.
    10. If you have a hard drive failure, it is not recommended to try to reinstall the operating system. First of all prove that the hard drive is OK as advised before trying to re-setup. In addition, if you can, back up your data before reinstalling the operating system. In all likelihood, that's what you have to do but for a hard drive replacement.

    I repeat that a failing or failed hard drive is the most likely scenario. Other more distant possibilities include

    • A failed or failing disk controller (almost certainly on the motherboard)
    • Boot from the hard drive is disabled in the BIOS (highly unlikely if this anomaly is intermittent)
    • Some sort of weird for the failure of the BIOS
    • Option 3 mentioned in the previous post (unlikely unless your PC has been internally inspected/modified or subject to vibration displacement/hitting more/remove etc..)

    10 iOS does not well at all. Notes is much more difficult to edit with touch screen as before. How can I erase my start of all the widgets screen? I might want to go back to iOS earlier.

    "How can I erase my start of all the widgets screen?" is the only question that you asked, so here's the answer:

    Some widgets may not be deleted, but you can move the widgets that you use most on the front screen and keep the ones you don't want a rear screen. Or, you can take the widgets you want and move them to a single folder.

    Since the other thread (How to disable the Welcome screen?) has been "answered" from a new:
