• How can I pass a string reference in java?

  Hello!
  
  My question is how to pass a string reference in java.
  I tried to declare my variable, instead of using 'string xxx = 'f';', I used 'string xxx = new String ("f");':
  
  Public Shared Sub main (String [] args)
  {
  String xxx = new String ("f");
  StatusEnum result2 = getErrorPointStr (xxx);
  }
  
  
  public StatusEnum getErrorPointStr (String text)
  {
  StatusEnum testStatus = StatusEnum.PASS;
  StringBuffer buffer = new StringBuffer();
  buffer. Append ("123");
  text = buffer.toString ();
  Return testStatus;
  }
  
  After the call to getErrorPointStr (String text) function, xxx = 'f'
  If it does not work.
  
  How can I solve this? It is very important, the function will receive String and nothing else.
  Thank you!

  This question has already been answered.

  It is very important for me to know this.

  And already know you, 'cause I told you in the first answer here.

  Perhaps if you explain what you're trying to accomplishand why you think that need pass a reference string - in other words, why you think that a reference string is a solution to your problem - in fact we could be able to move forward with help you to solve this problem.

  And No, despite what you think, your problem isn't that you 'need to pass a string reference. It's your solution to the real problem of attempted (and failed). So let's get down to that, shall we?

• A query can be passed to the user-defined function?

  Hello
  I created a function that takes one parameter and returns a value. Now tha value that is passed into the function comes also from a query, so can I pass that Charly directly in the parameter?
  I tried this but it is giving error: ORA-00936: lack of expression.
  

  select ID from table1
  where areaid=f_getAreaID(SELECT sec FROM table2 WHERE artid='3232') and 
  type='p002' 

  Above code is in error. How do I get my requirement?
  Note: Assume that query to the function will always return a value of skis.
  
  Published by: bootstrap on August 28, 2011 12:13

  Subquery must be enclosed in parentheses. Function parameters must be placed in brackets. Therefore, you should use

  select ID from table1
  where areaid=f_getAreaID((SELECT sec FROM table2 WHERE artid='3232')) and
  type='p002'
  

  Remember, it must be a scalar subquery (subquery returns one or no line).

• Can be passed to the formula of the procedure/function the column value?

  Cf_value is back after some calculation using the main request.
  
  Can be passed directly the value of column of formulas of procedure without assinged to placeorder?
  as below...
  
  
  f_convert(:cf_value,new_value);
  
  ---------------------------------------------------------------
  
  My procedure is...
  
  
  PROCEDURE f_convert (val1 val2 in number, number) IS
  
  BEGIN
  
  val2: = val1 * 100;
  
  END;
  
  
  If anyone knows pls answer me...

  In fact, if there is that other calculations he (in Proceudre)

  Can I used is like below?
  ---
  PROCEDURE f_convert (val1 val2 in number, number) IS

  BEGIN

  val2: = val1 * 100;

  return (val2);
  END;
  ----

  A procedure cannot return a value, the return in my previous post clause was part of the function for formula column.
  Let's say you have a column of forms of so-called CF_2, then the function because it will be like:

  function cf_2formula return number
  is
   val1 number;
   val2 number;
  begin
  
   val2 := :cf_1 * 100; -- or val2 := val1 * 100 --parameters not allowed in formula column function
  
   -- All the other code that you need inclusive of calling function, procedure as in any PL/SQL block can be placed 
  
   return (val2);
  
  end;
  

  Any calculation can be used in the service of the formula column

• Passing a reference to queue as a sequence with LabVIew API parameter

  Hello

  I'm running a sequence of Labview with the entryPoint.Run method.

  Now, I want to pass a reference to queue to TS for use as the parameter for a stage of the action (the action must information sent through this queue). I tried to move the queue as a parameter for the valVariant parameter of the object of Subproperty seuqence.

  LabVIEW throughs 1 error when I try to setValVariant.

  The reason why I want to do it is because I want to integrate the execution of the sequence in my draft framework for an actor.

  Is it better to move the refs to the queue as a reference to be able to send data to an application running?

  Thanks in advance

  Michael

  Hi Michael,

  It is not possible to use references of LabVIEW in TestStand queue, since they do not share the same instance of the application. You can pass a reference to queue as an integer (U32 or I32), but you can not use in TestStand.

  I found 2 ways for you to use:

  You can use the Action engines in LabVIEW to encapsulate the queue. There is some information about this option in this thread:

  Solved: queues of LabVIEW and TestStand - Forums of Discussion - National Instruments
  http://forums.NI.com/T5/LabVIEW/LabVIEW-queues-and-TestStand/TD-p/2554231

  However, with this option, you must make sure that the motor Action shift register leaves no memory

  .

  The recommended practice is to create the queue in TestStand using Synchronization Manager and then open this queue in LabVIEW. An example is available for this option:

  I hope this information is useful for you!

• Pass a reference to the shared variable

  I use two shared variables in a loop where I write one and read each other.  I need to repeat this loop 5 times, but each loop uses a different pair of shared variables.  These variables are shared between a vi on the computer and a cRio.

  It would be ideal to incorporate this loop into a Subvi where I can pass a reference to the two shared variables in and then read and write in threw these references.  Then I could just call this Subvi 5 times, instead of copying and pasting the loop 5 times.

  Is it possible that I can accomplish this?  I can't find an example that would achieve this.

  Thank you

  If I understand correctly, you can use the mode programmatic access to shared Variables and it would work.

• passing a reference structure in a dll (cvi) of EEG, a mistake-17502; System-level exception.

  Creates a container that matches parameter in cvi dll.  I have the container facility by checking the death of struct C using packaging of 8 bytes.  With the help of the adapter of the CVI has created an action.  When the step is executed, I get this error (17502; Except for system-level).

  Have you created a type of data customized to represent the struct (you say that you have created a container)? You specify the field for each variable type structure in the custom data type? You must configure each field to say TestStand what data type to use, for example, a number can be a double, int, short, or char, and TestStand needs to know that in order to create a corresponding structure correctly. Did you create an instance of this type to pass into the dll function? Thanks for posting the definition of structure, you use c if possible, also, please describe exactly how you configured each variable in the definition of type (custom data type), that you have created. If you are able to provide more information, we can try to see if there is a problem with the custom data type configuration.

  You can also take a look at what makes your function, the function code could lead to a breach of access or another exception of system level. You can launch the editor of sequence of CVI process debugging to debug your code module, or change the setting of the ICB card adapter configuration run the code a an external instance of the CVI.

  Hope this helps,

• Pass by reference

  Hi all

  I'm developing an application for the tests used in automobiles. I just had a tot that is possible to pass the array by reference. I know that the method of passing by reference by getting the reference to the table and pass the reference to the Subvi. To do this I need to create a display board and reference for the same should be passed to the Sub - VI. But this is nothing but pass the data to the Subvi by value. The only difference is that the table indicator will not be created in primary vi rather a control panel will be in Subvi.

  Is it possible to directly wire data without creating a control wire Subvi and Subvi table, use as a ref table and retrieve the data. You mean, son of data must be connect to the Subvi terminal, but terminal in sub - VI should give the Ref for that data.

  All ideas are welcome.

  Thank you

  Yogesh

  Maybe you are looking for a reference value of data? It can be a 2D array, for example.

• Passing a reference to a type definition for a Subvi

  I created a type definition that I would use in my application. This definition of particular type is also the control of front panel to my top level VI. I wanted to pass a reference to this control to my sub - VI so that they could dereference as needed and in very rare cases, update the values on the front panel. However, as I created the application I noticed that I was breaking the control reference that I have updated the type definition. This implies that they type changes the reference that I change the type definition.

  How can I do to build the reference I need or there at - it another way to proceed that works as well. Even if I can't make a reference to the control that is bound to the type definition, I'm ready to move to a Variant that can accommodate the reference until I can build the type of data (reference) inside my SubVis.

  Hello

  You must simply pass a reference of generic control to the Sub.vi and then cast to the specific typedef. You will need to place a control dummy of this typdef on your Sub.vis Frontpanel and hide.

• reference error function

  I have the following question

  Code:

  FUNCTION FN_FME_RPAD

  (

  p_s_cadena in TANK,

  ) RETURN VARCHAR2 IS

  v_c_Space VARCHAR2 (32767).

  BEGIN

  v_c_Space: = LPAD (p_s_cadena, 10, 'x');

  RETURN SUBSTR (v_c_Space)

  END;

  variable: = FN_FME_RPAD (p_s_cadena = > 'tricampeon_1981');   OK, that works perfectly ok

  from there, it gives me error

  Select FN_FME_RPAD (p_s_cadena = > name)-fails here

  in results

  of the customer;

  within the selection it gives me error pass by reference, but here works well

  Select FN_FME_RPAD (name) - it's ok

  in results

  of the customer;

  Then? This is what Solomon and I said... before 11 that does not allow notation named for the function parameters in sql...

• How can I save the references to the elements of the xml elements page?

  Hello

  I am trying to add coordinates of the page elements to their associated as xml attributes xml elements.

  I can easily create xml help items

  myDocument.mapStylesToXMLTags ();

  Now, I want to browse the xml document and find details of each element of the associated page and then add them in the corresponding as attributes xml node.

  In other words, I'm trying a code (assuming that all the nodes as children of the root for simplicity) as follows:

  for (var i = 0; i < myRootXMLElement.xmlElements.length; i ++) {}

  var myElement = myRootXMLElement.xmlElements.item (i);

  var myElementsPageItem = * did not find a reference of function / correct documents *.

  var myBounds = myElementsPageItem.visibleBounds;

  addORupdate (myElement, "y1", myBounds [0]);

  addORupdate (myElement, ' x 1', myBounds [1] ");

  addORupdate (myElement, "y2", myBounds [2]);

  addORupdate (myElement, ' x 2', myBounds [3] ");

  }

  In my example of document all the xml that is created by mapStylesToXMLTags() are history of type.

  So I need a way to refer to the corresponding (or rectangle) page element of the history so that I can add information about contact information item xml as attributes.

  Thank you very much...

  myElement.xmlContent.parentTextFrames was not defined in the xml document that is generated by mapStylesToXMLTags()

  After some research the object model, I found my data in

  myElement.xmlContent.textContainers [0]

• Pass parameters with a function that is a parameter to another function.  Is this possible?

  Hello

  I have some difficulty to pass parameters to a function that is passed as a parameter.  In the code for my application I am instantiating this class five times: they are buttons in a menu.  In this category, I had an onRelease handler that does a number of things when a button is released, which is to call a function defined in the level of enforcement of the code.  My problem is that I don't know how to send parameters to the functions.

  In my StandardButton class I:

  class StandardButton extends MovieClip
  {
       
       /* define properties */
       private var selected:Boolean = false;
       public  var btnMenu:MovieClip = null;
       public  var execFunc:Function;
       
       /* define constructor */
       public function StandardButton()
       {
            trace("Standard UI button created: " + this);
            this.onRelease = releaseHandler;
       }
       
       /* define methods */
       public function releaseHandler()
       {
            if (selected) {
                 
                 //this["bg"].gotoAndStop("normal");
                 //selected = false;
                 
            } else {
                 
                 //show the normal state of all other buttons in the menu set
                 for (var i:Number = 0; i < btnMenu.btnList.length; i++)
                 {
                      this._parent[btnMenu.btnList[i]].bg.gotoAndStop("normal");
                      this._parent[btnMenu.btnList[i]].selected = false;
                 }
                 
                 //show the select state of the button
                 this["bg"].gotoAndStop("select");
                 
                 //execute the function attached to this button
                 execFunc();
                 
                 //set the selected boolean for the current button
                 selected = true;
                 
            }
       }
       
       
       /* define accessors */
       public function set execFunction(instructions:Function)
       {
            execFunc = instructions;
       }
       
       public function set buttonMenu(menu:MovieClip)
       {
            btnMenu = menu;
       }
       
  }
  

  In my application .fla file, I have this

  //This is the function that will be executed when the user presses the button
  function autoModeHandler (param:String) {
       
            trace("You pressed the " + param + " button");
            
                                
  }
  
  init();
  
  masterContainer.menuContainer.Auto.execFunction = Delegate.create(this, autoModeHandler);
  

  The function is successfully "sent" to the class of StandardButton, but without any parameters.  How can I send parameters for the instance of the class with the way I had it built.  Any help is greatly appreciated!

  Thank you for your time and help!

  You can pass parameters as you're passing that work.  you just need an instance of StandardBtn.

• Can I pass name of user and password for strobe playback as parameters?

  A question related to the SSO on.

  Can I pass name of user and password for playback of strobe as parameters so that the user does not need to be prompted for the name of user and password for protected content? In other words, Strobe detects a need for authentication, but rather establish a dialog box to prompt the user, it just extracts the name of user and password transmitted and transmits it to the license server?

  If no such function is available, can anyone point to a simple sample plugin, where I can spend the long name of username/password or a token to the license server, perhaps through the object connection or flow? I looked at the example of Akamai, and it's quite complicated with little documentation.

  Thanks in advance for your help.

  Hi Lei,

  The SMILPlugin seems to have a bug when used with a proxy plugin.

  Please follow these steps:

  1 starting the SMILPlugin source code: http://opensource.adobe.com/svn/opensource/osmf/trunk/plugins/samples/SMILPlugin

  2. open the SMILMediaGenerator class.

  3. go to line 123. You should see the following code snippet:

  If (! isNaN (duration) & duration > 0)

  {

  (videoElement as VideoElement) .defaultDuration = duration;

  }

  4. replace by this excerpt:

  If (! isNaN (duration) & duration > 0)

  {

  Assuming that videoElement is that a VideoElement is wrong (I guess that we can find a better name for this variable?)

  Since any plugin proxy will break this code. Iterate through the string until you reach a VideoElement proxy

  We can add a deffensive code just after the iterator, unless we should always have a VideoElement on top.

  var temp: MediaElement = videoElement;

  While (temp is ProxyElement)

  {

  Temp = .proxiedElement (temp as ProxyElement);

  }

  (temp as VideoElement) .defaultDuration = duration;

  }

  5. check that everything works with this patch.

  6. Let us know if that fixes the problem.

  7. connect the bug and submit the patch (with a link to this post on the forum) here: http://bugs.adobe.com/jira/browse/FM

  Thank you

• How to pass parameter in the function using the select statement?

  Hello
  
  I had a problem. I can't pass as parameter to the function by using the select statement. But it can pass as a parameter using the "code". How can I solve this problem?
  
  For example,.
  Select * from table (SplitFunction ('HS750020, HS750021')) < < < this work.
  
  but
  
  Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) < < < do not work.
  
  Thank you for trying to help him. Thank you.

  Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36'))< do="" not="">

  Try like this

  select * from table(select splitfunction(lot_no) from tracer_search_schedule where job_id='36')
  

  Just make sure that your subquery returns only 1 row.
