How to restore checked value?

Hi, i am trying to create a page, which enable user to edit their personal profile.
There are checkboxes, which are generated dynamically from database.
then in my database, i will have a table, storing the memid and the checked id.
when user enter this edit personal profile page, i will use the same method of generating this list box, but, how do i assign the value, or values, which have been checked and checked the boxes again?
beside that, i also have radio button which are generated dynamically.
how can i do that?
i am using jsp,
how to i assign let's say, text box value and radio button value?
hope you all guys can help me with this.
really need your help.

No that's Java syntax in a bean to check a radio button once a user has selected it. You have to first store what the user selected using a post to the server. This function returns the "checked" part for enabling what the user selected if you have to reload the page. For instance, the user didn't select a required field and you want to redisplay what they have already selected on another JSP and allow them to then select whatever it was that was required. The article is all about validating user input within JSP vs. Javascript. JSP is a bit more work, but cleaner and 100% effective instead of using Javascript.
Hope this helps.

    --and restore previous schema.
    alter session set current_schema = SYS_CONTEXT('USERENV','CURRENT_USER');

  • How does APEX check for null values in Text Fields on the forms?

    Hello all,
    How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
    I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
    All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
    Declare
    v_valid boolean;
    Begin
    IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
    v_valid := TRUE;
    ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
    v_valid := TRUE;
    ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
    v_valid := FALSE;
    ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
    v_valid := FALSE;
    END IF;
    return v_valid;
    END;
    My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
    Thanks

    See SQL report for LIKE SEARCH I have just explained how Select list return value works..
    Cheers,

  • How to insert check box value in table?

    Hi all
    kindly help me how to insert check box value in database. what code i have to use as i am new in programing.
    thanx in advance

    Hi,
    There is no "Check box" in a table, a check box is a GUI (Graphical user interface) item.
    What you want is to store a boolean value in a table. For that you can use the varchar2(1) datatype and store Y or N. (or anything else)
    (you cannot define boolean as a datatype for a column).
    If you're using a front-end application like apex then it might be useful for you to read the documentation about chekc boxes :
    http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10497/check_box.htm#CHDDFBFH
    (for the rest if it's Oracle Forms then everything is already said).

  • HT1766 I have manually back up my iphone few days back, and my contact got missing the next day. i restored my back up from iTunes, however, my contact did not get restored. How do i check if the manual back up did actually back up my contact or not?

    I have manually back up my iphone few days back, and my contact got missing the next day. i restored my back up from iTunes, however, my contact did not get restored. How do i check if the manual back up did actually back up my contact or not? How do i get back my old contact in my phone?

    Your entire second paragraph is so confusing I am going to ignore it.
    But I may be able to answer your first and third paragraphs, which seem to address the same question.
    I wonder where your iPhone states it was backed up yesterday.  I am going to assume that you see this under Settings > iCloud > Storage & Backup.
    If that is true, then the backup from yesterday is in iCloud.  The one and only way to restore an iCloud backup is to do this on your iPhone:
    Settings > General > Reset > Erase All Content and Settings
    That will cause your iPhone to begin a setup process.  As part of that process, assuming you enter the same Apple ID you used when you created the iCloud backup, you will be offered the opportunity to restore from it.

  • Using PL/SQL Block how do you check if the character string value is aA-zZ

    I have a pl/sql block that I prompt the user for password and I load the string into an array and interrogate each index(entry) to see if it is "aA-zZ".
    How can I check if the value entered is Alpha.
    I need to do the same for number and Special character. Please advise. Thanks

    Thanks to All of you. The desired solution to verify complex password that enforces desired security policies. An example that I am using is the following:
    IF NOT (regexp_like(sz_complex_pw,'[[:digit:]]') AND regexp_like(sz_complex_pw,'[[:alpha:]]') AND regexp_like(sz_complex_pw,'[[:punct:]]') AND regexp_like(sz_complex_pw,'[[:upper:]]'))
    THEN
    --dbms_output.put_line('Password is not complex...');
    RAISE sz_err_pw_complex; -- Complex Password is not compliant
    END IF;
    DBMS_OUTPUT.PUT_LINE('Complex Password is in Compliance...');
    EXCEPTION
    This was helpful to me and I trust others will find helpful.

  • HT1212 If I never synced to itunes and I restore the device. Will I lose unstored data? How can I check to see the last time my phone was backed up if I forgot the passcode to my phone?

    If I never synced to itunes and I restore the device. Will I lose unstored data? How can I check to see the last time my phone was backed up if I forgot the passcode to my phone?

    If you can't remember your passcode, you'll need to restore your phone.  If you never synched to iTunes, all data on your phone will be erased.  No way around this.

  • How to Insert check box value into database column

    Hi All,
    I had checkbox group in a region which is using an LOV......and having 18 items in that lov.
    i.e. Total 18 checkboxes in Total. User has to select only 2 checkboxes from that 18.
    I created two columns for storing two values of checkboxes. How to insert two selectives in two columns.........Moreover, How to give the query i.e. how to know which values are selected.
    Please Help me in achieving this. apart from the two columns (Focus1,Focus2) .......One more column(l_spo_val) is there which is a foreign key.
    My Insert Statement is like this:
    INSERT INTO SPO_RESEARCH_FOCUS VALUES(l_spo_val
    ,:P4_RESEARCH_LIST_1
                        ,:P4_RESEARCH_LIST_2);
    Please narrate the code if possible.
    Thanks,
    Sekhar.

    Hi Denes,
    I saw the example in your workspace and it is the same what exactly i want and instead of storing in one column i want to store the two selected values into two different columns. Also i need to restrict the selection of checkboxes upto 2 only. So If the user tries to select the third check box it doesnt have to accept.
    Even I am ready to change my table as according to your example i.e. creating only one column. Store the values of selection into that column.
    I was unable to see how u wrote the logic (Code) for your example in your workspace. It helps alot if you provide me the code for that example(Multi Checkbox One Column).
    I was facinated after watching your examples in your workspace and am very much interested to know more about Apex.
    Please help me insolving this as it is long pending issue for my requirement.
    Thanks a lot again,
    Sekhar.

    If it's showing the connect to iTunes screen then you will need to do that.
    But Apple don't provide any method to update the first gen iPad to iOS 5 (nor do they support downgrading the iOS version).

  • Today all my Bookmarks disapeared from Safari, when i checked my iphone they were there and then went away the same happened on my ipad. Any ideas on how to restore?

    Today all my BookMarks disappeared in Safari, when I checked my iphone I watched them disappear from there and the same on my iPad. I then thought why not check my Parallels side and Windows Explorer. They were there for a few seconds and then also gone. Any ideas on how to restore and stop this from happening again? My iCloud setting are set for Safari sync.

    Then you have misunderstood what iCloud is.
    First. It is not a back-up service. It is a sync service.
    That distinction is very import. A back-up service would have backed-up your bookmarks but iCloud's function is to synchronize your data, in this case your bookmarks, to all your devices. A backup service, by it's very nature, would allow you to roll back to a previous version of your data or file. No such roll back function is present in iCloud's services.
    For example, if you add a bookmark to Safari on your Mac that same bookmark will be added to all your other devices that are connected to your iCloud account. Also, if you delete a bookmark it will be deleted from all those devices.
    iCloud does not make a distinction between deleting one or all of your bookmarks and it will do the same to all your devices. It does not know that was not your intention. That is why it is very important to have Backups and Apple makes it very easy using Time Machine and a simple hard drive connected to a computer.
    Let's see if your bookmarks have actually been deleted or if there is another problem.
    Your bookmarks are stored in a .plist file the following directory, ~/library/Safari/Bookmarks.plist
    To get to that directory go to the Finder, select the Go to Folder… menu item in the Go menu and enter ~/library/Safari/ in the field provided. There you will find the Bookmarks.plist file.
    Select it and hit the space bar on your keyboard to see a preview of the files content. Does it still contain references to your bookmarks? If it does still contain references to your bookmarks then something else is going on and we'll have to find a different solution.

  • I have iphone 3gs. I upgraded its software through itunes but it stopped reading sim. Then I restored but since then iphone is locked with message to insert a carrier compatible sim. I've checked my sim is ok. How to restore the iphone?

    I have iphone 3gs. I upgraded its software through itunes but it stopped reading sim. Then I restored but since then iphone is locked with message to insert a carrier compatible sim. I've checked my sim, it is ok. How to restore the iphone?

    I'm going to make some guesses here. You bought your phone second hand. In other words, not from Apple and not from your carrier. What you got is a hacked phone that was originally carrier locked, most likely to AT&T in the US. You are NOT in the US. (If I get any of this wrong, please tell me).
    What has happened is when you updated the software, it was re-locked to the original carrier.  ONLY the carrier can authorize an unlock. If it is locked to AT&T, you're out of luck as they WILL NOT unlock an iPhone for any reason.
    If it's locked to another carrier, you will have to find out what carrier that is (you can NOT tell by looking at the model number) and find out if they unlock iPhones. If you can't find out, or if they do not, then your only real option is to sell the phone and purchase one from a LEGITIMATE source.
    You can find out who the supported carriers are here: http://support.apple.com/kb/ht1937

  • How to Access Radiobutton Check Value

    Hi all,
    I'm using Oracle 10g Forms Developer and I want to know how to access radio button check value, that means how to know that the current radio button is checked or not. Thanks in advance

    you assign each button the representing value in the properties.
    So you can just check if the radiogroup-item has the value you assigned the button, something like:
    IF :BLOCK.RADIOBUTTONITEM='A' THEN
