using the value null with a function

• Can I use data value references with a functional overall?

  Can I use data value references with a functional global?  I am trying, but it causes problems:  I run the attached VI with "new DVR" selected.  Then I run it again with "return array" and I get the error 1556: "The reference is invalid. This error might occur because the reference has been deleted."  It seems to have forgotten the DVR, but I thought it should be stored in the shift register.
  
  Another odd thing:  In my VI, if I try to connect the wire shown in "something strange", then the type changes (from U16 array to DBL), i.e. it doesn't recognize the type referenced by the DVR.
  
  I want to pass a very large 4-dimensional array between parallel loops with a functional global.  To avoid memory problems, I want to use a DVR and in-place element structures.  If that's not allowed in Labview, I will try passing it through a user event or notifier.  Any problems with those alternatives?
  
  Thanks.
  

  I received a response from an engineer applications OR on this subject, and it seems that it is perhaps a problem with Labview.  They are working on it, so I'll go ahead and close this discussion.

  Thanks for the help,

• swfbridge has the value null with multi soft version Flex 3.3

  I use Flex 3.3 to implement a version of multi Flex AIR App (unique security and areas of Application of brother) using the Bootstrap method. When my main app load a sub app in a field of brother I find that the property of the SWFLoader swfbridge is null and therefore, I am not able to send all events between the main and void / apps. I saw a post on these forums that with Flex 4.0 you need to add the option in MXMLC

  -includes = mx.managers.systemClasses.MarshallingSupport. This class is not there in Flex 3.3? Is there something equivalent, that I can do with Flex 3.3?

  How to use the values of the input variables on the table select statement names?

  Hello

  Here's a way you can use dynamic SQL statements for this task:

  CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

  (

  in_schema IN VARCHAR2,

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  in_first_date DATE DEFAULT SYSDATE - 1,.

  in_last_date DATE by DEFAULT NULL

  )

  RETURNS INTEGER

  AS

  -IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

  -contains all the dates in the in_first_date of the range through included in_last_date

  - and it returns 0 if there is no such lines.

  -If in_last_date is omitted, the search only the data on in_first_date.

  -If in_first_date is omitted, it defaults to yesterday.

  -Time parts of the in_first_date and in_last_date are ignored.

  -Declaring variables

  sql_txt VARCHAR2 (1000);

  v_is_true INTEGER.

  BEGIN

  sql_txt: = 'SELECT COUNT (*).

  || 'FROM ' | in_schema | '.' || in_tablename

  || 'WHERE ' | in_datefield | ' > =: d1'

  || «AND» | in_datefield | '< >

  || 'AND ROWNUM = 1';

  dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE");  -For debugging

  Sql_txt EXECUTE IMMEDIATE

  IN v_is_true

  With the HELP of TRUNC (in_first_date) - d1

  TRUNC (NVL (in_last_date

  in_first_date

  )

  ) + 1                -- d2

  ;

  RETURN v_is_true;

  END is_ydaydata_to_table;

  /

  DISPLAY ERRORS

  If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above.  In this way, you can easily see exactly what will be executed.  Comment out the call to dbms_output under test is completed.

  Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future.  For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days.  The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

• Calculated field with the currency formatting, and hiding the values null

  I am designing a PDF form for quote and I have a field defined to multiply the amount of an article and the unit price to the total price.  There are 5 lines on each quote, and if users are citing only 1 or 2 items I want the values null in fields unused price extended to be hidden.

  I did it with the following script

  If (event.value == 0) event.value = ";

  But when I enter the quantity and total price of price is displayed as a regular number (100) instead of currency ($100).

  I can format to currency with

  Event.Value = util.printf ("$%.2f", event.value);

  I don't know there's a way to combine to give rise to such a situation then, so if the field is 0, make null and if not then format as currency but I don't know how to do it.

  Any help would be appreciated.

  Andrew

  Newer versions of Acrobat hide zero for fields values using the number format and with a currency symbol. »

  But since you can't control the updating of user systems, you must use a small function documented for formatting numeric fields on the fly.

  With the extended price field set to 'None' format, you can add the following script to the Validation script "Custom" or add it to a custom JavaScript calculation. The "Custom Validation will work with any method of calculation. Note that the form must be cleaned or recalculated to see the result of the validation script change.

  if(Event.Value == 0) {}
  Event.Value = ""; set the field value to null to a value of zero
  AFNumber_Format (2, 0, 0, 0, "", true); number with no currency symbol format
  } else {}
  AFNumber_Format (2, 0, 0, 0, "$", true); for the format of the values non-null for number with the currency symbol
  }

  The positional parameters are the number of decimal places, the Style separator, negative value Style, Style of (unused) currency, currency symbol, the currency symbol Pre-hanging chain.

• Siri in him sending text with the value 'NULL '.

  When I say, "Siri, text my wife, 'X', ' Siri responds correctly,"here is your message to Jill: 'X'. "" "  "Ready to send it?"  I say 'Yes' and sends the message.  As soon as I get a text from my carrier saying the recipient of the message was invalid.  100% of the time, I see that Siri has sent a text with the value NULL.

  I tried to restart my phone.  I tried to remove and re-add my contacts.  Anyone else having this problem?  Someone knows how to solve?

  If it's by the carrier, you should contact them and see what they receive in return for their side. Ive had Siri send messages for me and I have never seen this one IOS.

• Treatment options for form (use the value of a form field to select a shared list or a web redirect page)

  Hello

  I tried something with the processing of the forms which doesn't seem to work. I wonder if the function really works or if I'm doing something wrong.

  Here is an example of what I do: I have a form that I want to use. I add "Web Page redirection" processing step to my form. When I click on the processing step to set up, under "General settings" there is an option that says "Choose how the launch of destination page is selected." In this drop-down menu, there are three options: always redirect to the same landing page, use a drop-down list to select the landing page and the value of a form field allows you to select the destination page. I have a hidden field on the form that contains the URL of the web page to which I would like to redirect. When I select 'Use the value of a form field to select the landing page', I select the hidden field to the field that contains the URL of the web page to which I want to redirect. It's my setup. However, when I submit the form, nothing happens, I do not redirect to the URL contained in the hidden field... This function still works? I'm doing something wrong? I can't seem to get the function "Use a drop-down list to select the destination page" to work either. The same thing happens when I try to use the "Add Contact to shared the list" processing step. I add the name of the list that is shared in the field hidden, but the contact does not appear in the shared list... These functions still work? If yes how do I configure them?

  Thank you!

  Well, I understood the problem of the shared list... You must add the ID of the list shared in the hidden field. I had to use Firebug to see the real ID of the shared list. Once you have the ID, use you it as a static value in the field. If the HTML code of the form will look something like this:

  If you do not use the lookup data ID. You use the ID real asset on the shared list. You must use something like Firebug to find.

  I'm glad everything is working.

• Assignment of identifiers automatically or using the value of basic in the rules

  The question is quite simple. I want to order the instances of an entity. How these bodies are classified are of no importance. The problem is that the only information available on instances of the age, which may be one of several bodies and makes impossible to order. Is there any way to assign an identifier automatically apply this ranking, say 0... the number of instances - 1 or is - it possible to use the value of an instance of rules?

  A loop is a bad choice here - a recursive function would end in the same logical dilemma on the tie-break as you you. (If I can offer any advice it would be that the rule loops should be a last choice as a general rule, not a first, they are certainly not as easy to manage as recursive functions in a standard programming language).

  Essentially, you want to work on the price of the ticket (IE an attribute at the level of the entity of ticket):

  the price of the ticket =
  0; If the number of tickets more expensive than me + number of tickets as well as me<= number="" of="" free="">
  nominal value * number of tickets I have to pay for my price/number of tickets, the same value as me; If the number of cheaper tickets than me < number="" of="" free="" tickets="" and="" number="" of="" tickets="" more="" expensive="" than="" me="" +="" number="" of="" tickets="" same="" as="" me=""> number of free tickets
  otherwise the price of the ticket face value =

  where the number of tickets I have to pay for my price = number of cards of the same value that me - (free tickets - number of cheaper tickets than me)

  As I said, you can use alleged relationships to help you work on:
  number of cheaper tickets than me
  and
  number of tickets as well as me

• What is the empty string, the value null in the column, or...?

  I use Oracle 11.2, a table tb_class as follows:
  
  TB_CLASS (number (3) id, varchar2 (32) nm, seqNum number (3));
  
  1, 212
  2, "under", 12
  3, 'qq', 12
  
  Select * from TB_CLASS where id = 1 and n = null;... .no selected line
  Select nvl (nm) in the TB_CLASS where id = 1; ... 1 selected line
  
  Any know what's in the column of row id = 1 nm? I thought that it is an empty string, but why it returns no rows in the first query?
  
  Thank you!

  (1) in Oracle there is no difference between NULL and an empty string.

  (2) NULL is never equal to what whatsoever (including another NULL). NULL is never spotty what whatsoever (including another NULL). You must use the IS NULL and IS NOT NULL operators to search for NULL values

  SELECT *
    FROM tb_class
   WHERE nm IS NULL
  

  or

  SELECT *
    FROM tb_class
   WHERE nm IS NOT NULL
  

  Of course, it is also possible that you declare that the NM column contains one or more spaces or it contains one or more non-printable characters and not a NULL value. That's why we asked you what dump (nm) returns

  Its because you have used a different username.
  Oracle produces a hash based on the user name and the password, not only the password.

  Therefore, you can not use the hashed password of a user to log on to the account of another user.

  You need to get the password hashed Suri and then connect you to suri by using the password hashed Suri (using the identified by the syntax of values)

  My essay is equipped to take a collection: initialized with values of say 3-4...
