• Site ads continue to use the proxy settings and I get the message "Authentication required" time and time again. I have stop advertisements to use my proxy settings?

  I have put my school proxy settings and use them very often. On some Web sites, ads continue to use these proxy settings (probably to show me ads based on my preferences or I don't know), and I get the message "Authentication required" time and time again before the end of the loading page. It's annoying because if I have several tabs open and am currently on another page while loading the website with the ads, I'm brought back to this page to authenticate. Can I get asked 3 times to authenticate while this page loads, and it takes forever to load because of this. I don't want to disable my proxy settings because I use it very often. I tried to uncheck the "Accept cookies from Web sites" and nothing happens, it's always the same. I want these ads to stop going through my proxy settings. How do I do that?

• Message authentication process

  Hey everybody!
  
  Alright! Here's my problem. I'm building a front end of the APEX for a pre-existing database that connects with many other applications. The way they authenticate the user is so weird. in any case, I need to call a message authentication process that returns an ID based on the user ID that after authentication, ID is used in most of the session.
  
  So far, I created an item hidden on the login page.
  And I have the appelΘ authentication process a package on the functioning of the database.
  
  Everything I need to do is somehow move the p_username in my service and have the return value to be stored in my ELEMENT. Is it possible through the block post authentication process? Or will have to create a process of PL/SQL on the first page that I connect?
  
  Thank you very much for your time

  Hello

  Why not call a 'function-wrapper' that code you yourself, which then calls the other function that you use, for example:

    ...
    v_code := pk_party_authtn.get_xref_id(v('APP_USER'));
    APEX_UTIL.SET_SESSION_STATE('XREF_ID', v_code);
    ...
  

  In this way, you can include custom logic, you need, while honoring the service you should use.

• Requires to change the message authentication code

  I got a pop up saying that I had to change a password in 60 minutes. I hit later and it will appear from time to time with a new amount of time. is this something Apple?

  N ° Apple doesn't care if you never change your password. If you have an e-mail account of company on the phone the accounting officer may require you to change your password on a regular basis, but it is unlikely that it would be within 60 minutes. Most likely, it's a scam. Just ignore it.

• convert NULL values to 0

  Hi guys
  
  am on 10g
  
  I have a Table with 7 fields (all numbers).
  
  Basically, I'm looking for a way to convert NULL values to 0 [zero], a process, a client wants.
  
  So no matter how the Table is large, that I must be able to do, what is the best way to do this? Example SQL? PL/SQL?
  
  Thank you.

• Alter the State of Session? -Apex form publishes text with null value

  Recently I discovered a problem with our Apex facility in which all selected as source for a text field value will eventually be displayed as a null value in the database.
  We run APEX version 3.2 in an Oracle 10.2.0.4 database using Oracle HTTP Server from 10 g companion disc.
  
  At first glance, everything seems to work as expected; I created a simple table called "oracle_sr" with 2 columns, as both not null:
  
  SQL > desc capacity.oracle_sr
  Name Null? Type
  ORACLE_SR_ID NOT NULL NUMBER
  TIMESTAMP NOT NULL DATE
  
  In APEX, the form wizard has been used to create a form on this table.
  After execution of the pages and you enter a value for the timestamp field, I can create folders without problem.
  
  The question arises when I choose a source for the timestamp field value.
  All the source options causes the same error (including a static value) so I'll focus on the SQL query to the source as:
  
  Select sysdate double;
  
  This should replace the date system in the area of text timestamp when the page is executed.
  As expected, the value appears in the text box, but when I submit the form to create the folder I get the error:
  
  ORA-01400: cannot insert NULL into ('ABILITY'. "" "" ORACLE_SR '. "" TIMESTAMP")
  
  I have worked with APEX for quite awhile and have successfully used this technique in many applications but just to begin to see this error in recent days. What's particularly odd about this message is by default postings "not null" created by the form wizard sees timestamp class as having a value. Session state information included below reports a value yet the database is to launch the ORA-01400.
  
  Someone has a similar problem? I have spent a good amount of time to try looking for this problem but can't seem to find any similar messages.
  
  I have included the release of my test page, debugging from what I see, it seems to be a value associated with the filed timestamp:

  If you have changed the Source Type of an element of database column to something else, so he cannot participate in the automated line choreography Fetch/automatic line processing (DML). You must leave the Type of Source, as it was and change the default value of the element fill when the ARF process retrieves a null value for the column.

• Masking elements at the entrance to the page if the NULL value in the database...

  Environment: APEX 3.1.1.00.09
  
  I have two 2 page elements I want to hide in 2 two instances:
  
  1. when the page first that the user enters a new round of data
  2 when the values of these objects have the value NULL, based on the recovered database
  
  I would like to than the items to be displayed if the values in the extracted line are not NULL.
  
  I already have the logic that allows you to hide items based on specific values being selected or changed by the user, but as requested (1) above I elements be hidden initially.

  Hi Gary - I thought today, it was a public holiday in the United States (something to do with a new President?)

  Anyway...

  You have reason - javascript there has nothing to do with Apex, so debugging doesn't even know it exists. To test if your script is run, the simplest method is to put messages alert ('message') in the code:

  function ...()
  {
   alert("Here 1");
   ...
   alert("Here 2");
   ...
  etc
  

  Name the messages in a way that you can easily identify what is running.

  It might be easier for you to explain what I did on my page (assuming it does what you're trying to do? Otherwise, just say).

  On the attributes of my page, I have added the following in the Header HTML parameter:

  <script type="text/javascript">
  function shA()
  {
   var l = document.getElementById('P6_LISTA');
   if (l.value == 'A')
   {
    $x_ItemRow('P6_TEXTA','SHOW');
   }
   else
   {
    $x_ItemRow('P6_TEXTA','HIDE');
   }
  }
  function shB()
  {
   var l = document.getElementById('P6_LISTB');
   if (l.value == 'B')
   {
    $x_ItemRow('P6_TEXTB','SHOW');
   }
   else
   {
    $x_ItemRow('P6_TEXTB','HIDE');
   }
  }
  </script>
  

  Strictly speaking, you could add this anywhere above the P6_xxx dishes - but the HTML header is the best place to add javascript functions.

  I have then four elements on the page:

  P6_LISTA - a selection list
  The Source is: STATIC: A, B, C, D, E
  and the setting of the attributes of the Form HTML element is: onchange = "javascript:shA();" »

  P6_LISTB - a selection list
  The Source is: STATIC: A, B, C, D, E
  and the setting of the attributes of the Form HTML element is: onchange = "javascript:shB();" »

  These two have display Null: Yes - Null display value: - Select - and Null return value: Z

  P6_TEXTA and P6_TEXTB are two normal text fields and not of special parameters.

  Finally, I have a region in the foot before displaying the point and the use of 'No. Template' which has a Source in the region:

  <script type="text/javascript">
  shA();
  shB();
  </script>
  

  (this pass just the code show/hide the page loading)

  Who help me?

• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• PersistentStore.getPersistentObject returns the null value?

  I use a random key to retrieve a shape of the object PersistentStore

  persist is PersistentStore.getPersistentObject (KEY);.

  Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

  For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

  I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

  In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

  At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                      persist = PersistentStore.getPersistentObject( KEY );
                      persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                      safetyTable = (Hashtable)persist.getContents();
                      orderedKeys = (Vector)persistOrderedKeys.getContents();
                      if (safetyTable == null)
                      {
                          safetyTable = new Hashtable();
  
                          persist.setContents(safetyTable);
                          persist.commit();
                      }
  
                      if (orderedKeys==null)
                      {
                          orderedKeys=new Vector();
  
                          if (safetyTable.size()>0)
                          {
                              Enumeration addressKeys = safetyTable.keys();
                              while(addressKeys.hasMoreElements())
                              {
                                  orderedKeys.addElement((String)addressKeys.nextElement());
                              }
                          }

• The body of the message to return null on os 4.5.0.18. When you use getBodyText()

  Hi all

  Today, when I debug my application on 4.5.0.18 device 8130.

  I implements FolderListener, when new messages coming,.

  I grap message object and want to analyze the body of the message to check if the message is what application you are looking for.

  Hoever, when I call Message.getBodyText (). It returns null.

  In fact, there a lot of message in the body of the message.

  is there any sweet experiencing this problem?

  What is work around?

  Thank you.

  getBodyText() will work on 4.5 If the body is 'plain text '. Otherwise, you will need to get the HTML content of the message and extract the text elements.
