How to clear all data when the form loading at the first time

hi
I am using JDevloper 10g and I have adfForm page, I want to clear all data when I load the page for the first time.
When I did it using RefreshCondition on the pageDef in the executables like(
<executables>
<iterator id="FinCompaniesInformaton1ViewIterator" RangeSize="10"
Binds="FinCompaniesInformaton1View"
DataControl="AppModuleDataControl" *RefreshCondition="#{adfFacesContext.postback==true}"* />
</executables>
the form didn't bring any data but the problem is the field in the form at the run time changed to read only. So how to make it inputText and clear the data inside it at the run time
best regards
Tarek Al Soudani

HI, I need your help. How can I delete all data, when I do not have the special security code, which I didn´t remember ? I also think, that I never create this code before. But I cannot put my settings back.

You must remember the code, if you can't then take the phone and proof of purchase to an Apple Store.

How to show all data when using more than one parameter?

Hi All,
I used a query like this to show the data in a report:
select col1, col2 // col1 and col2 are columns of tabale tab1
from tab1
where
tab1.col1 =
(case when :P_COL1 IS NOT NULL then // :P_COL1 IS A USER PARAMETER TO EQUAL COL1
:P_COL1 ELSE tab1.col1
end)
AND TAB1.COL3 =
(case when :P_COL3 IS NOT NULL then // :P_COL3 IS A USER PARAMETER TO EQUAL COL3
:P_COL3 ELSE tab1.col3
end)
The problem is when I run the report with paramters values or not, It shows the data which is not null for both col1 and col3.
That is when the value of col1 or col3 is null the report would not return that record!
I want the report to show all data not only values which is not null!
How to do this?

Rainer,
That where clause will fail when col1 in the table is null and the parameter has the dummy value. Consider the following:
variable p_col1 varchar2
exec :p_col1 := 'yourdummyvalue';
select
from
     select 'yourdummyvalue' col1 from dual
     union all
     select 'other' from dual
     union all
     select null from dual
     union all
     select 'X' from dual
) tab1
where nvl(tab1.col1,'yourdummyvalue') = nvl(nvl(:p_col1,tab1.col1),'yourdummyvalue')In this case, the query returns the row with null and the row with 'yourdummyvalue', where only the row with 'yourdummyvalue' should be returned.
You must do something like this:
where ( :p_col1 is null or ( :p_col1 = tab1.col1 ) )That one is the simplest and does not need a dummy value. Here are some other more complicated examples:
where nvl( :p_col1, 'yourdummyvalue' ) = decode( :p_col1, null, 'yourdummyvalue', tab1.col1 )or this:
where nvl( :p_col1, 'yourdummyvalue' ) = nvl2( :p_col1, tab1.col1, 'yourdummyvalue' )In the last 2 cases, it will not matter if the dummy value exists in the data, but they are unnecessarily complex.

How to show all data when data is authenticated

Hi,
Now I have an application where the user has to be authenticated and the data is only shown to that user. I want a way somehow I can access all the data from all the users who have lodged it. Like in the azure portal it shows all the data which was lodged
in the same way I want it in a account.
Thanks!
pratik

Hi,
I think you may need to use some logic in your application, such as filter the data according to the user.
Hope this helps

Itunes content and pics are NOT part of the backup that itunes performs.
Backing up, updating, and restoring iPad, iPod touch, and iPhone software
You should transfer any purchases from iphone regularly: File>Transfer Purchases , if they fail to be transferred when you sync.
You buy one and only one download. It is your responsibility to move/copy/backup your purchases.
You can try contacting itunes support and asking for an exception, but they are under no obligation to allow.

Me and my partner are currently using the same apple id and have no space left on our devices. We are currently waiting on the iphone 6 plus to arrive and don't know how to transfer all data to the new phones.

Me and my partner are currently using the same apple id and have no space left on our devices. We are currently waiting on the iphone 6 plus to arrive and don't know how to transfer all data to the new phones.?

I don't know if I'm asking this all in a way that can be understood? Thanks ED3K, however that part I do understand (in the link you provided!)
What I need to know is "how" I can separate or rather create another Apple ID for my son-who is currently using "my Apple ID?" If there is a way to let him keep "all" his info on his phone (eg-contacts, music, app's, etc.) without doing a "reset?') Somehow I need to go into his phone's setting-create a new Apple ID and possibly a new password so he can still use our combined iCloud & Itunes account?
Also then letting me take back my Apple ID & password, but again allowing us (my son and I) to use the same iCloud & Itunes account? Does that make more sense??? I'm sincerely trying to get this cleared up once and for all----just need guidance from someone who has a true understanding of the whole Apple iCloud/Itunes system!
Thanks again for "anyone" that can help me!!!

How to decrypt data when you can't get the private key in Windows?

I'm very confuse. My english is poor, but I try to say my question clearly.
When browser connects to a https website which needs client certificate to authenticate the identity, the browser will send client certificate to web server.
Then the web server will use the certificate to encrypt some data and send it to browser.
Then broswer should have private key to decrypt that.
But as I know, if I install a pfx format personal certificate, I can set can't export private key, which means you can't get the private key to use it. So how can
the browser decrypt the data without private key?
By the way, what is CSP, use CSP's interface can we use CryptoAPI
to decrypt data without private key?

Answer for question is "you cant"..

All of the data should be on your computer, simply sync it back.
If the update was done via iTunes on the computer, the first step in the process is a backup of the device.

And why not? Apple is selling these things like BigMacs. They can't make enough of them. You've been suffering since May because you refuse to get a decent router.
Can you imagine if a company that makes a refrigerator told me that I needed to upgrade my electrical system to rectify a problem with their device? What kind of response IS that?!?!
What if the problem with their device is that it requires a new-fangled "grounded" outlet and your circa 1890 house doesn't have grounded outlets. Would you refuse to purchase a $ 25 adapter on principle?

I transferred itunes library from old PC to new PC. The content all shows when I launch iTunes on the new PC now. The previous content does not show in iTunes but folder still looks like it is on hard drive on new PC. Suggestions on how to properly merge?

Before you connect any device to a new library go to the Devices tab of the the preferences panel via Edit > Preferences (Windows) or iTunes > Preferences (Mac) and ensure the box next to Prevent iPods, iPhones, and iPads from syncing automatically is ticked. You can now safely connect the device to your computer without the danger of media being automatically deleted or overwritten.
To get all your content off your connect your iPad to your new computer.
Then use a 3rd party piece of software to transfer your content
I have found Senuti useful but there are others listed in the article I linked to in a previous post.
https://discussions.apple.com/docs/DOC-3991
That will let you transfer your non purchased content
For Purchased content log in to iTunes on the new computer
In Itunes Store click on Purchased under the Quick Links section on the right.
Download any music by clicking on the cloud button

With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?
I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.
My problem is that, when I close the form and re-open it, it comes back to it's default presentation, regardless of the information already recorded in the form (including in the now hidden fields.
How to correct that
Thanks in advance for any hint you can provide.

I've had the same problem. This solved it...
Go to the "Form properties..." in the File-menu. Select "Run-time" to the left and in the box "Scripting" Preserve scripting changes to form when saved: choose Automatically (Script-based state changes are saved locally in an insecure fashion. This option cannot be used for certified forms).

Hi,
I had a similar problem and found help for it. Go to the "Advanced" menu and select Extend features in Adobe Reader. That will enable rights which may resolve your problem. If that doesn't work, there is a really helpful guy in here, Robert Levine. You may want to ask him directly.
Good Luck
