• PDF forms have problems displaying text and only appears when the field is selected

  Hello

  I created pdf forms to be distributed to the clients of the company. But we have some people complain about the visibility of the text. When they work as a team, the pdf they receive from a third party often appears limes or no text, the text is only visible when the field is selected. I need to find a solution for this, because our company's products are based on this form.

  If there is any information addition that I must add to understand what is happening and how to fix it, I'll be happy to write it.

  In society, we all have mac and forms where innitially created in Adobe acrobat 9 pro, but we now have Adobe acropabt pro XI.

  Thank you

  This is usually caused by the form is filled out and saved by a Mac user who uses the preview application to view the PDF file. More information is here: http://kb2.adobe.com/community/publishing/885/cpsid_88564.html

  It's a good idea to inform your users that Adobe Reader (or Acrobat) should be used to work with Forms.

• Getting the value null inserted in the back end when the field is turned off

  Hi gurus,

  I have a TOTAL field that is the sum of the other two fields in a form. I have disabled because do not have the user enter the value. The TOTAL field is the poster of the sum of the values in the front end, but in the back-end, the value is null. Please help me solve this problem. Thanks in advance.

  Have you tried to make the point read-only? Set the read-only item and try. You can do the unalterable element by two methods,

  (1) amend section-> go to read only tab-> read-only Condition Type: always

  (2) create a dynamic Action-> event: loading the Page-> Action: run the JavaScript Code-> Code:

  $('#P1_TEST').attr ('readOnly', true);

  $('#P1_TEST').css ('background-color', '#CDCDCD');

  Tom wrote:

  set the item read-only instead (not editable by the user but will present)

  Set the element value using the da no need to activate the item before submitting because the element is not disabled. Make the point read-only so that it will submit the value to the session and point cannot be changed always.

• Insert a NULL value when the field is empty

  Oracle 11 g 2
  
  Hi all
  
  This is probably a very simple question.
  
  Here's what's happening.
  
  I have a table:
  

  SQL> select * from mytable;
  
      MYCODE MYNAME          MYSAL
  ---------- ---------- ----------
        3456 Chris            8000
        9878 Bill
        6574 John             6500

  And I am running the following query:
  

  SQL> select 'insert into emp (empno, ename, sal) values (' ||mycode||', '||''''||myname||''''||', '||mysal||');'
  from mytable;

  gives me the following output:
  

  insert into emp (empno, ename, sal) values (3456, 'Chris', 8000);
  insert into emp (empno, ename, sal) values (9878, 'Bill', );
  insert into emp (empno, ename, sal) values (6574, 'John', 6500);

  If you notice, the second row has a sal as empty field. I want that he be null for what I can run this query to INSERT specific without having to manually enter the word "NULL" inside
  
  I think I need some kind of clause if-then here.
  
  If sal is NULL
  then the value NULL?

  Exactly!

  This condition IF-THEN-ELSE happening so often that they have designed a function for this.
  Instead of my_sal, use this expression:

  NVL ( TO_CHAR (mysal)
      , 'NULL'
      )
  

  It is:

  select 'insert into emp (empno, ename, sal) values ('      || mycode
                                                        ||    ', ''' || myname || ''''
                               ||       ', '      || NVL ( TO_CHAR (mysal)
                                                       , 'NULL'
                                          )

• Management when the percentage getting null values

  Hi all

  I'm writing a query that gives me the account, the total number of transactions, the total number of transactions that are being matched (from the same table) and finally a percentage.

  After the documentation and brushing my knowledge of sql, this is the query.

  Select A.ACCOUNT_ID,A.TOTAL_TXN,B.TOTAL_MATCHED,(B.TOTAL_MATCHED/A.TOTAL_TXN) * 100 AS PERCENTAGE

  FROM (select account_id, count (*) bdr_transaction TOTAL_TXN

  where

  value_date = January 9, 15 '

  Account_id group) has

  LEFT JOIN

  (select account_id, count (*) bdr_transaction TOTAL_MATCHED where)

  value_date = January 9, 15 ' and

  type in (1,2)

  Account_id group) B

  ON A.ACCOUNT_ID = B.ACCOUNT_ID;

  This query gives me almost the expected output (if it takes too much time), but when the result of the B.TOTAL_MATCHED column is null the percentage is also set to null.

  Is there a way or a workaround to handle this?

  There might be another way more quick/clean, to do so.

  Thank you

  TK
  

  Select ACCOUNT_ID, TOTAL_TXN, TOTAL_MATCHED, (TOTAL_MATCHED / TOTAL_TXN) * 100 AS PERCENTAGE

  de)

  Select ACCOUNT_ID, count (case when type (1, 2) then 1 end) TOTAL_MATCHED, count (*) TOTAL_TXN

  of BDR_TRANSACTION

• Show LOV only when the field is empty

  Hi all
  My surroundings:
  Oracle 10g on Windows
  Forms [32 bit] Version 9.0.4.1.0 (Production)
  Oracle Database 10 g Enterprise Edition Release 10.2.0.5.0 - 64 bit Production
  With partitioning, OLAP, Data Mining and Real Application Testing options
  Oracle Toolkit Version 9.0.4.1.0 (Production)
  PL/SQL Version 9.0.1.5.1 (Production)
  
  My problem:
  I have a field in a block, which is text_item and is linked to an element of LOV. I want the LOV appears automatically, whenever I tab in there, only when the element is EMPTY (for example when I try to insert in the block). When, upon request, it should show only the value in the field, and user can choose to activate the LOV, by pressing F9, if she wants to. It now displays automatically each time text agenda is a debate (works very well when the user is inserted, but annoying when she questioned the shape and trying to tab thru.) Every time she focuses on the field, LOV is popping up!)
  
  The current setting for the property on the element of text field: Type: text element
  The list of values: MY_LOV_NAME
  Validation of list: Yes
  
  Properties on MY_LOV_NAME
  Auto display: Yes
  
  Any suggestions? Or trigger level I can use, and if so, what build_in can use?
  New forms and will greatly appreciate advice from pros!
  
  Thank you
  Libran_girl

  It's very simple,

  IN once - new - item - Instance

  DECLARE
  V_LOV BOOLEAN;
  BEGIN
  IF: NOM_ELEMENT IS NULL
  THEN
  V_LOV = SHOW_LOV (LOV_NAME);
  END IF;
  END;

  Try it, you will get your result, if it doesn't work, try: block_name.item_name

• Box appears not to if the field is null

  I'm running Reports Developer 10.1.2.3 locally. Then I forms and reports Services on the application server 10.1.2.3. When I run the report locally by the developer reports if data of a field is the text box appears in any case, but when I save the report on the application server and re - compile there and then run only the fields that have data appear with the box around them.
  
  I saw another post and the fix was to make sure that all the fields had 'fixed' horizontal elasticity. I have both vertical and horizontal elasticity fixed value.
  
  Any help is appreciated!

• Move the cursor when the field is full?

  If I have a comb of 3 characters for the area code, how can I get the cursor automatically advances to the next field after the user types the third number? (LC ES2 9.0) Thank you!        ~ Carol

  On the change event of the area code field, you can use the JavaScript like this:

  var tempStr = xfa.event.newText
  If (tempStr.length == 3) {}
  xfa.host.setFocus ("TextField2")
  }

  The variable wil tempStr contain the entry selected by the user. Assuming that are code is 3 characters, and then when they get into 3 tanks the the update will change the field named in the setFocus command (in my case TextField2).

• Detect when the field gets the visibility on the screen

  Hi gurus

  I extended a BitmapField that when it is displayed on the screen is running a Thread internally in order to upload an image from a web server and then display it on the BitmapField. During the download of the Thread, it shows a dummy Bitmap.

  I am now the list 15 images on a screen in a VerticalFieldManager, and as soon as the application starts, 15 thread starts to download each image.

  When I run the application on the Simulator, with WiFi, all the images always get downloaded without problem all the time but when I run it on the device, sometimes the images are downloaded and sometimes some of them are not downloaded due to a "General socket error" (it is said the message of the Exception).

  This behavior is kind of random, I wonder that it is a restriction on the number of requests that a device can perform the carrier (by BIS) at the same time or something like that. Sometimes 15 images are always downloaded without problem.

  Now, the important thing, to circumvent the problem, what I'm trying to do is:

  Even if I add 15 images on the screen, only 3 images are visible at the same time (on the Curve 8520 in which I am testing now) so I'll try to find a way that only these 3 images run the download thread and when the user makes a scrolling to the bottom of the screen, the fields earning "visibility" on the screen start to run in their own thread too but didn't find a way to detect if a field of on the screen, and not only in the manager gains visibility of

  I try with:

  protected void onVisibilityChange(boolean visible)
  

  But as soon as the Manager is loaded on the screen, all fields run this even if events are now actually visible on the screen (they are in the lower part of the Manager)

  Is it possible to know when a field get visible only on the actual device screen and not on the virtual screen?

  Thank you!

  This might not work on all devices, but the first invocation of painting of the field is a good indicator.

  In my experience, the interface user of BlackBerry is very economical - everything that is not on the screen isn't painted. well, something that used to be on the screen and got a scroll being on could still be there in an internal buffer, so his painting could not called at all when it scrolls- but the first seems to be a pretty reliable indication.

• Format custom text field only when the field is filled

  I have created a form that I need to have the format of a text field "model:"& value of text field, then when it is empty so it is just empty.»

  I put event.value = "template:" + event.value; "." in the format custom properties of the text field it set to format correctly, but if it had not entered in this field he said always model: so what should I do for it to be only occur when there is something entered in the field.

  Change to:

  If (event.value) event.value = "template:"+ event.value; ".

• Calculated hidden field when the field is empty

  It is actually similar to a discussion a few months ago. Our forms are designed to be completed online, printed and sent by electronic mail, by fax or snail - mail. Many times the customer will simply print the form and complete it by hand. When I create forms with calculations, the ' $' or '0.00' appear; This makes it difficult for a person filling out the form by hand to work around these symbols/numbers. A few months ago I had a similar situation involving the percentages and the gurus on this forum (thanks, gurus!) has helped me with the following code and it worked perfectly to hide the fields calculated, unless something has been entered in the fields to calculate.

  A field with a format of 'None' user custom validation script:

  if(Event.Value == 0) {}
  Event.Value = ""; Set null field;
  AFNumber_Format (0, 0, 0, "", "", true); Set number format 0 decimals, not currency.
  } else {}
  Event.Value = event.value; keep the value;
  AFPercent_Format (2, 0, 0); Set the percentage, 2 decimal format.
  }

  This time, the problem involves single numbers (not percent, no change). I used the same logic and fields actually hide/as I want, but the numbers should be formatted with a comma between thousands and decimal with two digits after. I can't understand this! Can someone please offer some advice? Thanks in advance for your help.

  Make sure you use the correct quotation marks. Use quotation marks or single quotation marks, and not 4 single quotes.

  if(Event.Value == 0) {}

  Event.value = "; Set the field null (2 single quotes).

• Hide the subform if the field is null

  I have this script on a text field change event:

  If ((this.rawValue! = "null") |) (this.rawValue! = ""))
  {
  checkBoxThree.presence = "visible";
  }

  on the other
  {
  checkboxThree.presence = 'hidden ';
  }

  It displays correctly the checkBoxThree subform when the data entered in the text field.

  However, if the user goes back and removes the text, I want the subform to become hidden and is not. How can I change the script to achieve this?

  Thank you

  MDawn

  Hello

  try this script:

  checkBoxThree.presence = xfa.event.fullText.length == 0 ? "visible" : "hidden";

  Thks and greetings

  Just give the all fields are vertical elasticity is 'VARIABLE' and write the format trigger or apply the conditional formating.then it will work
  If one of the field if you give the property to vertical elasticity is fixed then it won't work.
