Check the DVR reference valid not null

I recently upgraded from LV2009 straight to LV2013 SP1 and noticed that it is possible to compare a DVR reference to data type 'not a Refnum ". How can you check if a DVR is valid already created?

Thank you

It is a behavior rather strange i can see in LV 2013f2 as well... However, I recommend you use the "Not a number/path/Refnum?" feature on the range of comparison.

  • Impossible to check the FPGA reference with "not a number/path/Refnum?

    How can I check if an FPGA interface refnum is valid?  It seems (LabVIEW 2009) that "Not a number/path/Refnum?" always returns true when connected to the output of open FPGA VI reference.  I write code that needs to be able to run without an FPGA for testing purposes, so I wrapped all calls to the FPGA in a case structure that I thought would run only if the FPGA reference is valid.  Turns out that they run ever, even when the FPGA reference is valid (probe shows it has a numerical value, and the FPGA VI is running).  I guess it's sort of similar to semaphore and appointment of references that have their own special function to verify the validity, but I do not see such a function for FPGA.  I have to cast to int and check if it is not equal to zero?


  • Apex 4.0.1; automatic fire validations not null for full items

    Hello

    I have a form with two elements (textarea and select list), where the fire automatic validations not null for these items, they were filled with values.
    Please, advise how to debug.

    Hi Edward,.

    No, they don't. Because the server does not actually know what happens in the browser. And because of security, which should also be separated, because otherwise someone could hide a page element and work around a not null not check on the server.
    So in your case you if the "not null" for a page element is conditional, you must set the indicator required for 'No' and create a regular validation "not null" with a similar condition your dynamic action.

  • Several validations not null

    APEX 4.2.1

    There is an old Configuration of Validation on the creation of several postings non-zero. As shown, the page create several validations not null in the generator has been contracted in 4.x. The configuration element required is nice, but it's not really allow us to conditonally run the validations (e.g. where X is pressed and page point value Y = Z). To do this, we need the point regular levels validation that has the standard Condition attribute. The nice thing about the validation of non-null out-of-the-box, associated with a page item, is it higlights, the element in question and provides a link to the error in the commit message.

    This implementation of a single element is fine but I'm not looking forward to this copy for page 2 dozen items I need.

    I suppose I could write a function returning Boolean validation using the view from the dictionary APEX but that would be a validation and you lose the functionality of the built-in validation mentioned above.

    Any ideas? How these validations be configured in bulk?

    Take a look at [url http://docs.oracle.com/cd/E37097_01/doc/doc.42e35127/apex_error.htm#BGBEEGIB]apex_error.add_error.
    Add_error logs an error as if it were a normal validation.
    Giving you the ability to record several validation errors using a validation.

  • How to create a validation "not null" unique for all elements in a page?

    Hello world

    How to create a validation "not null" unique for all elements in a page? I love textfields. Rather than create "not null" validation for each article, I would like to create a single validation control that will be used

    Thanks and greetings

    Bob, like u said I did the following:

    (1) less to create a button, there are 9 elements, and for each item, I put in the light of 'yes '.
    (2) under the button Delete, there is 1 point and have in light of the 'Yes' for the item
    (3) validation of the page defined for the 9 items under 'create a button' and put it to fire when 'create' button clicked
    (4) the page validation set for 1 number under 'remove' button and put it on fire when "delete" button clicked

    now, when I click on the 'create' button it shows same for the item under the "Delete" button that's a required element

    Sorry, I do not see this note. The required model will not work, there is no way to attach it to the button.

    The best solution is that the answer only a few answers to the top

    Create 2 validations page type as a PL/SQL with code

    1st validation
    
    :P1_ITEM1 IS NOT NULL and :P1_ITEM2 IS NOT NULL ...... and :P1_ITEM9 IS NOT NULL  include all 9 items
    
    Set the When Button Pressed to the CREATE button
    
    2nd validation
    
    :P1_ITEM10 IS NOT NULL
    
    Set the When Button Pressed to the DELETE button
    

    I think that this will be the best way to do it.

  • What index to use for 'where the pass is IS NOT NULL' query

    If I need a query of the form:

    Select * from INV_TABLE where R_TIMEOUT IS NOT NULL

    What type of index on the column R_TIMEOUT do you offer?

    Note that I'm only interested in the question of whether it is null or not.

    Thank you.

    It would really depend on how many lines was nothing compared to the number of lines not null.  An index of single column on r_timeout would be index only the non-null values, then, if most of the rows have a null value for r_timeout which could be quite effective as a path.  However, if most of the lines are not zero, then it is likely that a full table scan would be more effective, especially if you select all the columns in the table.

  • See the region if the recordset field is (not) "null."

    Facing another problem. The solution is probably going to be very simple, but so far I have not thought of her. That's what I'm looking for:

    Say you have a page with the title, the introduction of message and a news reading, more button. The table in which the ballots are stored got 5 columns:

    • ID (primary key, I)
    • date_entry (timestamp)
    • newstitle
    • newsintroduction
    • newsmessage (may be NULL)

    As you can see, the "newsmessage" column can be NULL because sometimes there are short messages. What I want to know is, if the "newsmessage" column is null, on the page that displays the records of news, the link "read more" should not be visible. It should show only when the "newsmessage" column is "not null", so got content inside.

    Thank you!

    Is this really a region you want to show or hide? I guess it could be, but DW normally like it better when the "region" is its own row of the table. I don't know how much time, even when I do not select the TR tag in the property inspector and apply a show or Hide Server behavior, DW still places the code inside the TR tag in the source code.

    So, basically, want you want to do is wrap the a tag that contains the text read more, in an If statement. I don't have the exact syntax for you, my PHP skills are still developing. Maybe an other people could help - or if you do not have a behavior show or hide (when the recordset is empty or non-empty), take a look at the way this code is structured and use it as a guide. But if you use Null/Not Null as your requirement, make sure that the field contains a null value.

    If you receive the null pointer exception to

    This means that you not give the good instance of vo. Do something please post your VO.xml and AM.xml files.

  • The file reference does not call. upload()

    OK it's going to take a little bit to explain but stick with me:

    I have two layers in the timeline, with no keyframes (coucheUn) and the other with a picture any key for every frame in the layer (layerB).
    In coucheUn, I have the script action to declare a variable of FileReference and I also declare and attach a listener object to the file reference.
    The listener object detects the event .onSelect to the FileRefernce (this event is generated when the service. the FileReference class's browse() is called - which opens a file browser and allows you to select a file). When called onSelect listener object executes the function. upload() FileReference which analyzes the file selected to a php script that downloads the file on my server.
    Function. for the FileReference browse() is called from an image in layerB. This is where the weird stuff that happens.
    When I test the movie the first time I enter the keyframe that calls the function. browse() all download routine work and the file is downloaded successfully. If I continue to the next keyframe (using navigation controls) and then navigate back and try to repeat the download process, then the file browser opens successfully, I select the file and then nothing happens. I have problems to identify the problem, for as far as I see it is as if it does never emit the onSelect event once the file is selected, which shouldn't be the case that the function .Browse works and a file is selected successfully. This would imply the php script does not work which is just ridiculous because it is a very simple script and it works the first time.
    Everyone has ideas, if you need more just information!


    UPDATE:

    Just did some tests and I'm completely confused, it's something the onSelect event. For some reason, it is not called / is not detected by the listener object. It's just weird because he calls good the first time you enter the frame, but if you navigate back, it is not detected. I checked the listener object was still in the scope of this framework and it seems to be, so I'm completely confused. The listener object is there and listening, the event that generated the onSelect event is executed but then never detected.

    Wooops, corrected just, said an another FileReference var on the following image with the same name, changed the name and works very well. Really really stupid of me.

  • How to check the data that are not digital?

    I have a varchar field and I would check for all of the lines where it does not contain a numeric value. How can I achieve this?
    Thanks in advance.

    One option is to write a small function

    CREATE OR REPLACE FUNCTION is_numeric( p_str IN VARCHAR2 )
      RETURN NUMBER
    IS
      l_num NUMBER;
    BEGIN
      l_num := to_number( p_str );
      RETURN 1;
    EXCEPTION
      WHEN others THEN
        RETURN 0;
    END;
    

    only then can you call

    SELECT *
      FROM some_table
     WHERE is_numeric( some_string_column ) = 0
    

    Of course, you can adapt the function to return the numeric value rather than a 1 or a 0 more.

    Depending on the version of Oracle (which you don't mention), you can also write a regular expression to search for things other than numbers. This can become a little difficult if you have to manage commas and dots as decimal separators and grouping because different regions use the symbols differently and have different rules about what are valid models.

  • Close the vi reference does not not on reentrant vi

    I have a reentry vi which will not close its reference. My program work experience, and once the experiment is complete, I use the FP. Open the property node (w / a fake wired to her) and a reference to close to automatically close the VI and reference. If I go into Windows Explorer to reopen the VI for editing, I get a popup 'a VI in memory with the same name cannot be replaced because it is in use. Click OK to open the VI in the memory. »

    Now, if stop my program courses through the experience by pushing the button exit (which runs the same FP. Open and close reference) and try to reopen the VI through the Explorer, there is no popup and the VI opens without a hitch. I can't figure out why there is this difference in behavior, or why I can't close reference VI.

    Is reentrancy issue?

    Thank you
