checking int null value

• Inline when checking for null values

  Hi, I'm currently stuck with a problem regarding the verification of null values. The problem revolves around an address line, where I want to display values such as roadname, number, zip code etc. The address line is supposed to be on a single line, no carriage return. The address line must be prepared for null values, if we say it have no house number. That's why I am attaching these tags with an if statement:
  
  & lt;if@inline:HOUSENUMBER!= "? & gt; & lt;? HOUSE number? & gt; & lt;? end if? & gt;
  
  But when I try this in my report, it seems that @inline BEEP do not take into account the signal no one checking the logical expression and always showing the content enclosed in the case. When I remove @inline, it works as it should, but there is a carriage return when the value is zero.
  
  Does anybody know a solution for this?
  
  Thanks in advance

  Hi Kim

  Hmmmm works for me. I noticed that you have a lack? just before the if. You can also try @inlines, it's a subtle difference in functionality.

  Even without the FI doesn't text collapse left anyway?

• NPE for rows with null values in the table of the adv

  I created the table adv, 2 columns, equipped with two text fields. Initially the col2 is empty,
  say that the structure is as follows:

                col1          col2
  Hdr         Question    Answer
  row1       abc           zxc
  row2       pdd           null (user doesnt enter anything)
  row3       zxc            lkj
  
  APPLYBUTTON

  When the user clicks on apply button I want to update these values in the table.
  
  I don't know how to do that, but that's what I'm trying to do. Please guide me the right way if its wrong.
  
  in LICS, I took the APPLYBUTTON action, got all lines of the object corresponding to the view, consulted with everyrow and I'm checking if there are values in the fields in the table, if the value zero, are simply print null. (we would not update on this line). . I could get o the part update, due to null pointer exception
  I get on the row line null pointer exception [1].getAttribute("Answer") for row2, it prints the value of row1 however.
  
  Here is the code I wrote:
  Set of rows from the rowset = (RowSet) vo.getRowSet ();
  Rank rank [] = vo.getAllRowsInRange ();
  System.out.println ("row.length" + row.length);
  for (int i = 0; i < row.length; i ++) {}
  String question = row.getAttribute("Question").toString ();
  String response = row [i].getAttribute("Answer").toString ();
  If (question! = null & &!("".)) Equals (question. Trim()))
  {
  System.out.println ("Question line" + i + "-" + question);
  }
  on the other
  {
  System.out.println ("Question line" + i + "is null");
  }
  
  If (response! = null & &!("".)) Equals (Answer.Trim ()))
  {
  System.out.println ("Response line" + i + "-" + response);
  }
  on the other
  {
  System.out.println ("Response line" + i + "is null");
  }
  
  Why the NPE survey code, I'm checking for null value and you want to print the value null in the logfile... I can not to getAttribute() on the null field, why can not just give me null in the variable I'm assigning to?
  
  You can guide me what approach to take, if it is not correct.
  I must examine DataDictionary and collect data there?
  Thanks in advance.

  Hello

  handle the exception of null on these two statements like this pointer

  String question = "";
  String response = "";

  Try
  {
  question = row.getAttribute("Question").toString ();
  }
  catch (NullPointerException e)
  {
  question = "";
  }

  Try
  {
  answer = row.getAttribute("Answer").toString ();
  }
  catch (NullPointerException e)
  {
  response = "";
  }

  Si ( !("". Equals (question. Trim()))
  {
  System.out.println ("Question line" + i + "-" + question);
  }
  on the other
  {

• How to check if the value is NULL in the script

  Please, tell which function should I use to check if the value is NULL
  as: If some_member = NULL then...
  
  Thank you very much

  If you mean #missing:

  Commission (IF (sales <> #MISSING))
  Commission = sales *. 1;
  Another Commission = #MISSING;

  This example is from the SER60

  PLEASE NOTE: For some reason, the not equals sign does not appear on the first line of the IF statement. (i.e. IF (SALES does not #MISSING))

• check NULL values with expressions

  I'm having a problem with an expression that I work with.

  I'm trying to produce a dynamic graph (among other information) that seems to be controlled by a stream - stream artificial is created by a handful of sliders and a wiggle expression.

  The chart is a simple graphic line which works very well. It is created with a null value (MarkPos) that the position is controlled by Captain wiggle expression that I've mentioned before, that follows.

  This next bit is where I have problems:

  I want to score minimum or maximum, the line has reached on the chart by moving a dotted line, one for weak points and the other for the top.

  Focus only on the bottom line;

  I have the following expression associated with the line, which brings together the current position of the value null (MarkPos) and compared with the current position of the line to see if it has all moved further away down, if she has it moving the line to the new pos are lower. However, all that happens is the line following the null value.

  x = thisComp.layer("MarkPos").transform.position.valueAtTime (time) [1];

  y = transform.position.valueAtTime (time) [1];

  z = transform.position.valueAtTime(time-thisComp.frameDuration) [1];

  If (x > y) {}

  [0, x]

  } else {}

  [0, z]

  }

  After a lot of debugging, I now know the issue is with the else statement - what his weight is compensating the to the high movement frame by frame 1 - so how do you define an order of "keep your current position in y ' in this case?

  [0.1] just it back to its original position and it is not possible to just have the ' if(x>y) {[0, x]} "bit without the"else {}.

  Suggestions fo how to fix this, or a better way to do it?

  This should give you the value of y min:

  p = thisComp.layer("MarkPos").transform.position;

  minVal = 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  minVal = Math.min (digraph, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], minVal]

  and this should give you the most:

  p = thisComp.layer("MarkPos").transform.position;

  maxVal = - 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  maxVal = Math.max (maxVal, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], maxVal]

• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• PersistentStore.getPersistentObject returns the null value?

  I use a random key to retrieve a shape of the object PersistentStore

  persist is PersistentStore.getPersistentObject (KEY);.

  Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

  For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

  I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

  In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

  At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                      persist = PersistentStore.getPersistentObject( KEY );
                      persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                      safetyTable = (Hashtable)persist.getContents();
                      orderedKeys = (Vector)persistOrderedKeys.getContents();
                      if (safetyTable == null)
                      {
                          safetyTable = new Hashtable();
  
                          persist.setContents(safetyTable);
                          persist.commit();
                      }
  
                      if (orderedKeys==null)
                      {
                          orderedKeys=new Vector();
  
                          if (safetyTable.size()>0)
                          {
                              Enumeration addressKeys = safetyTable.keys();
                              while(addressKeys.hasMoreElements())
                              {

• Remove the NULL values and update the value according to the logic

  Hello

  The problem data

  CREATE TABLE VOLA (SRNO, NUMBER, zero

  NUMBER, A

  INSERTION of REM in VOLA

  TOGETHER TO DEFINE

  Insert in VOLA (SRNO, ONE) values (1,237.94);

  Insert in VOLA (SRNO, ONE) values (2, null);

  Insert in VOLA (SRNO, ONE) values (14,56.965);

  Insert in VOLA (SRNO, ONE) values (15, null);

  Insert in VOLA (SRNO, ONE) values (16, null);

  I have to remove the NULL values in column 1, the problem is that the position of the NULL values are not fixed, and it can be any position. If all the lines of the columns are null, then throw it away.

  If multiple NULL values are here so I have to do the math as follows to update null with the eigenvalues

  1. If the first line is null then take the 2nd value in row and update it.

  2. If the lines between both is null then take avg of prev and next value not null and refresh it.

  3. If the last value in the column is null, then then take prev and update, in this case last two are null, so I have to take value of prev 14 value line update in

  15th and 16th ranks.

  I want to put this pl/sql logic, somehow, that I thought have loop and counter aapproach and loops through the elements and check and update.

  But always looking for something better before looking to write code. No idea or help will be useful for me.

  Rgrds Paavo

  Hi Paavo,

  Can I ask what you are trying to achieve by one of the labels by assigning null value?

  Null or an empty string are not useful as a tree node labels. Yet we could be as a minor bug that the area of the tree should be more robust in the JavaScript that it generates.

  Detect the problem (disappears from the dev toolbar) is not different from almost all JavaScript errors. Whenever any client-side behavior seems to not work, for example, no dev toolbar or a tree node does not expand, or a menu is not falling down, or something is not show or hide it should etc, the first thing to check is the browser console log. In this case, it shows the error ' SyntaxError: lack the name of the variable.

  Kind regards

• I have a HTML5 form that sends a null (%) if the user does not have a choice. It works fine, but I get an error of W3c on the value of '% '. Is there another way to send a NULL value?

  I have an HTML5 form that allows the user to select 1 of 6 provinces of Costa Rica. If they do not select a Province, I use php code to send a NULL value and the other selections research of the form looking for all Provinces. If they choose a province, we are looking for database records that are found in this province.  Currently I use the value = '%' as the selected value if the user does not have a choice. It works and looks in all provinces, but I get an error of W3c checking on the value = '% '. Y at - it another way to send a NULL value.

• number and date of type storage and null values

  Hi, I read that the date type consumes 7 bytes on the disc when it is preserved.

  It is also true for the value null in date type or the space for a null value in the column of type date is then reduced and equal to 1 byte?

  What about nulls (x) number?

  How can I check to make sure?

  Thank you

  Columns of NULL values using either no space (if they are physically at the end of the line), or 1 byte if not.

• Properties: Treatment of NULL values

  I wanted to ask you how you deal with NULL values, on the properties of JavaFX.

  Properties of the wrapper for the primitive data types like SimpleIntegerProperty or SimpleBooleanProperty Don t accepts NULL values.

  Example:

  1. IntegerProperty integerProperty = new SimpleIntegerProperty() )
  2. integerProperty. setValue (null) ;
  3. System. out. println () integerProperty. getValue ());

  Output is 0 (default value for "int").

  I think the primitive property wrappers (IntegerProperty, BooleanProperty and friends) as of the wrappers for primitive types. Probably they shouldn't really inherit WritableValue as which allows the call to setValue with a type reference, but I think that indigestion API would be worse than the implementation of setValue with a slightly incorrect signature. I would just avoid defining a wrapper of primitive type to null property: If you want to restrict yourself using set (.) instead of setValue (...) you are forced to spend in the primitive type: either you cannot pass null.

  If you want an integer property where null values are handled in an intuitive manner, use ObjectProperty .

  The test below shows that call setValue (null) on IntegerProperty assigns the default value. (Although I don't see the behavior documented anywhere).

  import javafx.beans.property.IntegerProperty;
  import javafx.beans.property.ObjectProperty;
  import javafx.beans.property.SimpleIntegerProperty;
  import javafx.beans.property.SimpleObjectProperty;
  import javafx.beans.value.ChangeListener;
  import javafx.beans.value.ObservableValue;
  
  public class PrimitivePropertyWrapperTest {
  
      public static void main(String[] args) {
          IntegerProperty integerProp = new SimpleIntegerProperty();
          integerProp.addListener(new ChangeListener() {
  
              @Override
              public void changed(ObservableValue observable,
                      Number oldValue, Number newValue) {
                  System.out.println("integerProperty changed value from "+oldValue+" to "+newValue);
              }
          });
  
          ObjectProperty objectProp = new SimpleObjectProperty<>();
          objectProp.addListener(new ChangeListener() {
  
              @Override
              public void changed(ObservableValue observable,
                      Integer oldValue, Integer newValue) {
                  System.out.println("objectProperty changed value from "+oldValue+" to "+newValue);
              }
          });
  
          integerProp.setValue(null);
          integerProp.setValue(1);
          System.out.println("setting integerProp back to null:");
          integerProp.setValue(null);
          System.out.println("setting integerProp to 0:");
          integerProp.setValue(0);
          integerProp.setValue(null);

          objectProp.setValue(null);
