If var! = NULL or if the variable is not NULL which is more correct?

• Why isn't 'if the variable does not equal null"work?

  Pretty simple thing, I thought, but it drives me batty...

  The Captivate 8.

  I have a widget for checkbox and assigned variables to all 6 boxes (framework1, evaluation2... assessment6). I also have a variable called 'null' (thanks to lilybiri). The variable has no value for her.

  
  

  So, I in my Advanced actions:

  
  

  If assessment1 is not equal to v_null or

  If evaluation2 does not equal v_null or

  If assessmen3 is not equal to v_null

  Le n

  See submit it (button)

  
  

  That means that if no the framework1, 2 or 3 etc... are verified, the assessment variables will be 'something' and not 'null' and should trigger showing button, but it does not work...

  
  

  Any ideas?

  
  

  Thank you!
  

  
  

  Sorry, I give up. You seem not to understand that you need another approach. Especially your answer 1 is not correct, why has the right of v_none, you are not in the mind of the person who checked it? 2 you give the opposite, what happens if the user has archived v_none really because he won't? Anywat that it is not possible to verify this with a single action advanced conditional with two decisions, because the sequence needs to be reversed for the second situation compared with the first situation. Everything should be in a single decision, with THEN/ELSE, but I do not understand the logic, so you can not help.

• How to check that the variable 'does not contain' value?

  Hello

  I use CP 7.0.1.237.

  We want to use the widget text box for a custom quiz and verify a response. While we understood how to check the existence of certain key words, we are not able to find a way to check that the content does NOT contain certain keywords. For example, we want to ensure that the text entered in this widget does not contain a "Transformation" and "Non-compliant.

  Is this possible at all?

  Thank you

  Anthony

  Anthony, it works perfectly. Created this conditional action with 4 decisions. I used the interaction of training text scrolling in CP8 (because now you can control the variable - which means I might have a Reset button):

  First decision:

  

  Second decision (the third is similar to the following)

  

  Fourth and final decision

  

  I put the variable words (v_first... v_fifth), it's a reflex I use since I shared actions that much. The variable associated to the ETB (you can now reset an empty var in CP8) is v_TextArea and the Boolean value that will decide if positive feedback (StarOK) should be shown is v_TA_OK. If you want to display a negative feedback, put this in the ELSE part of the final decision.

  FYI: it took 15 minutes, including the creation of assets and the variables and tests. Personally I would have needed more time to do it in JS, but that's just me.

• Value of the variable local not even as indicator

  I use enforcement to highlight to debug a problem. I noticed that when the front panel indicates the Boolean value true, the execution has highlighted this is show as false.

  Why would such a thing happen?

  My request is based on the continuous acquisition model. The problem I'm trying to debug is that somehow my application don't ignore the sequence error when I want it. I thought that it isa condition critical competition, but with highlighted performance I expect to see it happen and I did not.

  I have attached the screen show and the vi. I'd appreciate any help.

  Thank you.

  All shows this small 'F' near the tunnel of the structure is the value of the local variable was the last time it was read. the 'F' will not change magically to something else until the next time the local variable is read, and which depends entirely on the rate of this loop loop. When you perform a execution highlighting, loop rate is very slow and since many other places write so that the indicator via local variables, has no way to tell, from the diagram, that given its value at a time. Only the façade shows the current state, that's what the façade is.

• Marquee Learning Interaction; Assign the Variable does not transfer all text.

  Captivate v9. The use of the Interaction of learning of text scrolling to capture text user input by assigning a Variable name. On the next slide, insert the Variable in a text caption. The text entered in the previous slide in the scrolling text is truncated. For example, the entry of 2 or 3 sentences (100 + characters) generates only the first 50 or so displayed in the text caption.

  When you inserted the variable in the dialog box did increase the length of the default 50 to what you want?

• While the loop does not stop until 2 more clicks

  I must say that I'm really not familiar with LV, but Im learning.

  So why is that after I clicked on low stop, I had to click my OK button twice, then my program stopped. Why can't it stop immediately?

  Furthermore, if I want to do some of the dice to table, which wire do I missed?

  Thank you!

  Hi RawtoLV,

  You have a while loop in loop a while. When you run the other while the loop stops when you press the stop button, the inner circle while loop always executes. Since your OK button use latch release, what I noticed is that when you pressed the OK button, it quickly into position from true to false, which never stopped during the operation of loop (maybe because of the wait). Can I ask what are you actually doing with the structure of sequence?

  I would suggest using the event structure in place (http://zone.ni.com/reference/en-XX/help/371361K-01/glang/event_structure/):

  

  

  

  Here are some information about the structure of the event:

• Problem with LDAP in the APEX and not in sql query * more

  Hello everyone.
  
  Hereby, I refer to an existing thread: Query LDAP APEX
  
  I have a problem using LDAP in the APEX (DB version: 11.2.0.2.0;) APEX version: 4.0)
  
  I get "Authentication failed" by their SUMMIT. However, when I run it in SQL * more (SQL Developer) (I created it as seen in the referenced forum thread) it works! Can I use my own function, but that looks like reinventing the wheel.
  

      l_ldap_host := 'oursite.be';
      l_ldap_port := '389';
      l_ldap_domn := 'oursite';
      l_ldap_user := i_username;
      l_ldap_pass := i_pw;
      l_ldap_base := 'ou=oursite,dc=oursite,dc=be';
  
  
      dbms_ldap.use_exception := true;
      
      l_session  := dbms_ldap.init(l_ldap_host,l_ldap_port);
      l_retval   := dbms_ldap.simple_bind_s(l_session, l_ldap_domn||'\'||l_ldap_user, l_ldap_pass);    
      l_attrs(1) := 'name';
      l_attrs(2) := 'title';
      l_retval   := dbms_ldap.search_s(
                      l_session, 
                      l_ldap_base, 
                      dbms_ldap.scope_subtree, 
                      '(sAMAccountName='||l_ldap_user||')',
                      l_attrs,
                      0,
                      l_message
                    );
  
      l_retval := dbms_ldap.count_entries(l_session, l_message);

  We must search the sAMAccountName because that contains our login credentials (dennis.surname). The common name is just our full name (Dennis Surname)
  
  
  At the SUMMIT, I have these settings:
  
  * LDAP host: oursite.be
  * Port: 389
  Use SSL: No SSL
  Use exact DN: No.
  * String DN: ou = oursite, dc = oursite, dc = be
  * Search filter: sAMAccountName = % LDAP_USER %
  
  
  When I try to test it I get "Authentication failed" but I don't know why. It works very well in sql * more (in the the same pattern of course!) so I have really no idea what I'm doing wrong. In addition, the message comes instantly and sql * more it takes about a second to authenticate.
  
  I tried so many things! remove the 'or '. Connect with my name, change 'cn = % LDAP_USER %' filter, connect with dennis.surname and Dennis Surname, using exact DN,... and all the possible combinations of them... Nothing works.
  
  I can go further by using my own function, but I really want to use the settings of the APEX, because it's so much easier.
  
  Thanks in advance for help out me!
  Dennis

  Hi Dennis,

  Try this

  The exact use DN Yes value
  Change your DN string to

  %LDAP_USER%@domain
  

  or

  domain\%LDAP_USER%
  

  The authentication uses a simple_bind_s. You must use the same syntax in these text boxes. You actually do a single with bond

  dbms_ldap.simple_bind_s(l_session, 'sAMAccountName=' || l_ldap_user, l_ldap_pass);
  

  It does not work. It's the syntax to use in the search for search_s filter.

  Please keep in mind that the apex_040100 (for apex 4.1) user must connect the rights on the domain server.

• Changing htmlText in textfield on the stage does not work in CS6 more

  I have a problem in Flash CS6 (MacOS X 10.6, German) with an old FLA file created in Flash CS3:

  Flash CS6 seems to ignore the HTML of the text dynamically.

  There is a dynamic onstage text field with text inside.

  Anti-Aliasing is set to "Readability", "render text as html" is activated, the fonts are included - all right.

  I want to change the text in the textfield with ActionScript (AS2):

  _root.myTextField.htmlText = "this words should appear the"BOLD"< b > < /b > or < i > < /i > italic."

  Strategic outcome in Flash CS3:

  The words must appear in bold or italic.

  Flash CS6 strategic outcome:

  These words should appear in bold or italic.

  "Bold" and "italic" have disappeared...

  This behavior occurs only with textfields already on the scene, no textfields created with ActionScript.

  How to solve the problem?

  Test file: html_text.zip

  your file runs on a pc and fails on a mac.

  You can google something like: mac embed fonts flash cs6 problem

  or you could try embedding fonts dynamically and using css.

• Why not the type of the variable is a string?

  Hi, I need your help. \(´o `)/

  When I'm "DropDownList.items", the type of the variable dose not become the 'string. '
  Why?

  / * If when 'isNaN' command was returned to 'true', while the type of the variable is "string", if it was referred to 'false', so no 'chain '.  *****/

  Alert ("ddownlistItems [" i + "] plus" + IsNaN (ddownlistItems [i]));

  }

  }

  Win.Show ();

  ------------------------------------------------------------------------------------------ ----------------------------------------

  I tried this script, "alert" has been returned "ddownlistItems [0] = false '.

  but the setting of the components dropdownlist used table of "channels".

  Why not the type of the variable is a string?

  Thank you.

  Because you do not test the chain only the index.

  try...

  Alert (ddownlistItems [i] + "=" + isNaN (ddownlistItems [i] .text));

• VI refuses to run when the published network shared variable is not available

  I have a VI of logging data on my PC that gathers data from several sources, including several shared variable published network hosted on an RT target.

  The problem I have is that the data logger VI refuses to start if the target RT is disabled and the VI is abandoned if the network connection is interrupted.

  Is there an easy way to detect when running, be published these variable network are available and use a placeholder value, if they are not rather than the current behavior of refusing to work?

  I saw many people using data sockets, but I try to avoid the overhead of setting up and testing a loop of treatment relatively complex network on both ends when the network has published shared variables are so simple to use and works perfectly as this abnormal behavior.

  You can replace them with programmatic access (shared variable aperture and friends) and the dummy data placeholders if the variable is not accessible.

• Bind variables does not not with the process of the page.

  I am under APEX 4.1 and try to use the new send an email page. I like the wizard and everything works when I get statically from SUBJECT and BODY, but when I try to replace variables as bind & P1_FROM the message fails with "Invalid address" because the variable is not passed, it just shows up as & P1_FROM. Any ideas?

  The & P1_FROM needs a point after ".".

  So exactly as shown here

  &P1_FROM.

  Why do I get invited to enter a "/" when running the script in SQLplus? Even if I insert a / after the username 'impression' statement I am invited to enter an end delimiter.
  
  In addition, I would like to access the user name value in the following SELECT statement. However when I as code above the value of the variable is not taken. Instead, the user is prompted to enter a user name.
  
  No there is no way to 'transfer' of the value of the SQL user name?

  You're confusing SQL * more variable substitution (those with '&') and bind variables.

  Replace the "& username" with: username as shown below:

  SQL> variable username varchar2(100);
  SQL> begin select user into :username from dual; end;
    2  /
  
  PL/SQL procedure successfully completed.
  
  SQL> print username;
  
  USERNAME
  ---------------------------------------------------------------------------
  SCOTT
  
  SQL> select * from all_tables WHERE owner=:username;
