I have a LOV custom, but I don't know how to recover the selection?

Hi all
I want to recover my lov user selection, but I don't know much about the syntax.
Please advice.
Currently, I have attached a script to a button so that I can bring out a LOV.

______________________________________________________________


DECLARE BOOLEAN a_value_chosen;

BEGIN
Message ("LOV is gg to pop up.");
a_value_chosen: = Show_Lov ('LOV27');

IF this is a_value_chosen
Message ("you have not selected a value.");
Bell; RAISE Form_Trigger_Failure;
ON THE OTHER
/ * I don't know how to recover the selection of the user here... * /.
Message ("you selected a value!' |") SELECTION);

END IF;
END;

There is another way to get your selection of LOV... you can not use this concept...
You must return value LOV to some parameter/item, while creating LOV. in order to check if its recoveries or not...

Suppose that you have returned the value to a parameter named RETURN_VAL then...

DECLARE
  A_VALUE_CHOSEN BOOLEAN;
BEGIN
  MESSAGE('LOV IS GG TO POP UP.');
  A_VALUE_CHOSEN := SHOW_LOV('LOV27');

IF :PARAMETER.RETURN_VAL IS NOT NULL THEN
  MESSAGE('YOU HAVE NOT SELECTED A VALUE.');
  BELL; RAISE FORM_TRIGGER_FAILURE;
ELSE
  MESSAGE('YOU HAVE SELECTED A VALUE!!!' || :PARAMETER.RETURN_VAL);
END IF;
END;

    You must have installed a Windows 7 64-bit driver (if it exists)
    for this. Do you have? Otherwise, navigate to the web site of the camera
    manufacturer, search, download and install it.

  • I don't know how to change the size and quality of the text on the screen on Windows 7

    I just installed a new Windows 7 but I don't know how to change the size and quality of the text on the screen.  I tried all the things normal, resolution, size of icons, dpi etc but nothing gives me what I want.  The text in clear 'wonderful' thing is just terrible.  When I go through the 4 steps I see no text boxes which make the text nothing better.  All options are terrible, so the result on screen is too terrible.  When I do any huge I do not get a full screen of things - view the Start button disappears or I did not closing small cross at the top - of the suggestions to inprove the situation?  I must mention that my screen/monitor is 2006 - I need to buy a new one?  How much is this Windows 7 is going to cost me, or maybe I should go back to XP!

    I sincerely thank all you smart "technicians" for all the answers you always gave myself and all others who ask questions.  I'm not too smart with all this new technology as I fell into it very late.  I am now in my 60s and only started using a pc when I was over 50 years so...  In any case, I asked a question about the size of screen resolution and text and received much good advice from all that you guys.  I had recently changed in XP to Windows 7.  However, the bit of advice that I was given in 'Cyberking' here at the Portugal had set the resolution of the screen, the advanced settings, 75 to 60 Hertz Monitor tab.  Very basic, and the first question asked the technician (Lady) was "what size is your screen?  Naturally as a smaller screen that any 'techno' would be considered dead aid, solving the problem was simple and straightforward without me having to stretch my knowledge and my skills by downloading all programes weird (to me) or do the funny stuff in the bios or something else.  I send this comment to you for you to realize that the simple solution is not always bad and maybe we should go for the easiest first and then work up to the more difficult ones.

    Just for you all to see - now my screen resolution is perfect, the text on the screen is clear and legible without difficulty, even though the size of text and icon is small.  Clarity is all!

    Thank you all once again!   Best regards, Blondie blue.

    my phone asking me always Apple ID password of the account that I did not create. I have this account in my settings, but I don't know how to remove it. Thanks for the reply.

    There are several places an identifier Apple is used on an iPhone.

    • If it's the Apple of a former owner of the phone ID, and it is in settings/iCloud grace to find my iPhone activated, ONLY the person who set up the Apple ID can remove (see: find my iPhone Activation Lock: a mechanism of extraction of the previous owner)
    • If it's the Apple ID in Settings/iTunes & App Store just log out, then log back with the correct ID of Apple.
    • Do the same for iMessage and Facetime, if that is where the Apple ID is used.
    • If he is asked during the updating of the apps means that applications have been purchased or downloaded using this code from Apple. To resolve this issue, you must remove the application, and then buy with your Apple ID.

    I already bought a CS6 Design and Web Premium download. I want to install it on my new laptop, but I don't know how. I still have my series/code number produced of my purchase in December 8, 2012. What can I do for my transfer software from my old computer to my new computer?

    Just install and activate it.  If you need to download the installation files, you can do so on the link below.

    Your license allows you to have two active facilities, so if you have only one, you can always install on another machine without touching the original installation.  If you do not want the original installation, then you should disable at least opening one of the applications and selecting help-> Deactivate.

    CS6 - http://helpx.adobe.com/x-productkb/policy-pricing/cs6-product-downloads.html

    You can also download the demo version of the software through the page linked below and then use your current serial number to activate it.

    Don't forget to follow the steps described in the Note: very important Instructions in the section on the pages of this site download and have cookies turned on in your browser, otherwise the download will not work correctly.

    Essentially, your question is here. you read a lot of lines to return alone. Do you need them all? To get them you do full table scan on the two tables? An index would help?

    Hello. I have windows xp and Explorer 8 - no other firewall.  There are a few sites that I just can't log in, gmail and sometimes cpanel of my site.  My computer says check my firewall, but I don't know how.  The port 80, 443, 21 ftp https http says I have no idea what it is.

    I think you may have (or get) a virus or other malware/parasites that some of you changed may be used in Internet Explorer.  You should run a Malwarebytes scan on your machine: http://www.malwarebytes.org/

    Reset the settings of your Lan IE:

    In the menu Tools of IE, select Internet Options, then click on the 'Connections' tab and then click on the button "network settings."  Deselect the options (remove all checkmarks that might be present).

    While staying in Internet Options, click on the "Advanced" tab and then click on the button 'Restore advanced settings'.

  • I built in webcam on my laptop but I don't know how to get to the top to see?

    original title: built in Webcam

    I built in webcam on my laptop but I don't know how to get to the top to see?

    What should I go for?

    First of all, your system must have appropriate drivers for your webcam and then you need an application to use it.

    You could get the app and drivers both with your PC you can use these, otherwise go the manufacturer's Web site and find what is appropriate for your system.

    You can try Windows Update for drivers too.
