• Number of items in the target to host DMA FIFO

  Hello world

  I would like to transfer a set of datapoints of an FPGA to a RT-host controller using a fifo DMA. If I use the 'Get number of items to write' function on the FPGA target, can I get the total number of items in the two buffers, or just one on the FPGA target?

  (see http://zone.ni.com/reference/en-XX/help/371599H-01/lvfpgaconcepts/fpga_dma_how_it_works/)

  The FPGA will have no idea how big the DMA is on the side of the host.  He can't see his own DMA buffer.

  Get the number of items to write just tells you how many items are not used by the DMA (ie the number of items that currently write to the DMA without waiting for items to be offered by the host reading).

• Display the number of items in the Favorites/Wishlist?

  Is there a way to display a number of items in the Favorites/wishes? Support of BC said it might be possible with liquid markup, but I don't know how to do this.

  I would like to have a link to my page of favorites in my head that would show a total of points inside.

  Hey Evan,

  It is perhaps not exactly what you are looking for, however, is how you should speak and with some improvements in the code, you should be able to implement what you are looking for.

• Get the number of rows in the oracle table

  Hi all
  I want to get the total number of rows in the sql to the appmodule table.
  After you apply the criteria to view some on the view object. If he try with getallrowsinrange the number of rows found within the viewobject was but I want a total number of rows in the sql table.
  
  How can I get that
  
  I use jdev 11.1.1.5
  
  Thanks in advance

  I threw something together, quick and dirty, don't hesitate to optimize.

  Assuming you want the County table, I put the code in a subclass of EntityDefImpl since it is representing a table in the middle tier.

  public class EmpDefImpl
        extends EntityDefImpl {
    /**
     * This is the default constructor (do not remove).
     */
    public EmpDefImpl( ) {}
  
    //~ Methods ****************************************************************************
  
    public long getTableRowCount( DBTransaction transaction ) {
      String query = getQuery( );
      String countQuery = String.format( "SELECT COUNT(*) FROM (%s)", query );
      long count = 0;
  
      ViewObject vo = transaction.createViewObjectFromQueryStmt( countQuery );
  
      try {
        vo.executeQuery( );
  
        Row row = vo.first( );
        Number number = (Number)row.getAttribute( 0 );
        count = number.longValue( );
      } finally {
        vo.remove( );
      }
  
      return count;
    }
  }
  

  Depending on your card type, you may not get an oracle.jbo.domain.Number, but something else, so the cast may need correction.

  Usage example:

  public class EmpEditViewImpl extends ViewObjectImpl {
    public EmpEditViewImpl() {
    }
  
    protected void executeQueryForCollection( Object object, Object[] object2, int i ) {
      super.executeQueryForCollection( object, object2, i );
  
      EmpDefImpl def = ( EmpDefImpl )getEntityDef( 0 );
      long tableRowCount = def.getTableRowCount( getDBTransaction() ) );
  
      // Do something with it
    }
  }
  

  As you can see, the code is fairly generic. Also, you might be able to put this in a base extension ADF class.

• Data does not save in the dynamic table

  Hello

  OK, I found the root of all evil.

  To resolve this problem, you need to replace the script that caculates the dates in the dynamic table by another.

  Go to table calculate a remove the event script.

  Then, select the Date field in the first row of the table and add this script to its change event.

  var StartDate = $event.newText
  var DateFormat = "MM/DD/YY"
  
  if (StartDate ne $event.prevText) then
            var selectedDate = Date2Num(StartDate, DateFormat)
              var selectedDay = Num2Date(selectedDate, "DD")
            var selectedMonth = Num2Date(selectedDate, "MM")
            var selectedYear = Num2Date(selectedDate, "YY")
            var firstDay = Date2Num(Concat(selectedMonth, "/", "01/", selectedYear), DateFormat)
            var lastDay = 0
            var dayNumber = firstDay
  
            $event.change = Num2Date(firstDay, DateFormat)
  
            for i = 0 upto 30 step 1 do
                      if (Num2Date(firstDay, "MM") eq Num2Date(dayNumber, "MM")) then
                                dayNumber = dayNumber + 1
                                lastDay = dayNumber
                                Table._Row.addInstance(1)
                                Table.Row[i].Date = Num2Date(dayNumber - 1, DateFormat)
                                Table.Row[i].Day = Num2Date(dayNumber - 1, "EEE")
                      endif
            endfor
            Table._Row.removeInstance(Table._Row.count - 1)
  endif

• Problem with the name of the dynamic Table

  Hi all
  
  I can't using a dynamic table name. I have the following code...

                           FROM (SELECT DocRef, VerbID, DateUpdated

  What I am doing wrong?

  You cannot use a variable instead of a table name. You must build the dynamic SQL. Search for IMMEDIATE EXECUTION or DBMS_SQL in Document Oracle.

• Report with multiple columns NUMBER of counts of the same table

  I am new to discoverer, so I'm a little lost.
  
  I work to create a report to show usage data and Knowledge Base of e-business. I have written using subqueries in SQL query that is in the format:
  
  Solution number | Soultion title | Solution views. Positive feedback | Negative feedback
  Title of 12345 _ 345 _ 98 34
  
  
  The entries 'Views', 'Positive' and 'Negative' are stored in the same table, so I do a count where setid = setid and usedtype = VS, then count where usedtype = usedtype and PF = NF
  
  Discoverer, I can get the number of solution, the title and THE totals but I can't seem to understand how to get an ACCOUNT for three different things from the same table in the columns on the same line.
  
  When I go on change map-> select the items once I select the option NUMBER of the UsedType column in the CS_KB_SET_USED_HISTS table, I can't select it again. I also found way now to add a column based on a query entered.
  
  If someone could help it would be much appreciated.
  
  Thank you

  _ to correct spacing added.

  Hello
  You can separate the column with a case or decode.
  for example to create 2 calculations:

  case
  When usedtype = "PF".
  then - that contain both
  0 otherwise
  end

  case
  When usedtype = 'NF '.
  then - that contain both
  0 otherwise
  end

  After that, you can create the aggregation count on those.

• Change the number of items in the drop-down list box when running

  I'm trying to change the number of items in one of my boxes of comobo.

  I have been through the help and this forum and have the values to within the drop-down list box change very well, but in a scenario, I want to go to three options for 2. And according to other choices to 3.

  I guess I have to use a property node but I can't understand that one.

  You can use the method to reset to zero (using an invoke node) before setting the [Strings] (after setting the value by default an empty array) or create an Xcontrol (you can see examples of LabVIEW for xcontrol).

• How get the number of items in the ListView inside QML?

  QML/JavaScript newbe question here please.

  Suppose I have .qml

  import bb.cascades 1.0
  
  NavigationPane {
      id: navigationPane
      Page {
  ...
          Container {
  ...
                ListView {
                      id: listviewPlayers
  ...
  

  and I want to do something if ListView does contain all of the elements

      onCreationCompleted: {
          // this slot is called when declarative scene is created
          if (listviewPlayers.AllItems.count() == 0){
              // do something;
          }
  

  but when I run the present I get complain AllItems is not defined in this line:

   if (listviewPlayers.AllItems.count() == 0){
  

  What I doing wron? I can do the same thing in C++ without any problem.

  Thank you.

  Oh, this thing AllItems seems to be a 'Sentinel' or a magic value used in special cases, unrelated to this.

  I think that ListView manages all this, but defers everything to do with the pieces of data to the model, you don't have to go to the model for the data. ListView knows how VisualNodes (the components list item) he created at the time of the display on the screen, but also have to tell you the total number of elements in the model would simply duplicate work. (The reasoning behind this interpretant.)

• name of the dynamic table in a view

  How can I create a view of a table whose name is dynamically determined?

  for example, I have tables for each month table_2010401, the table_201402, the 201403 table and so on. I need to extract the data from the last table. This is more or less what I want to do:

  CREATE OR REPLACE VIEW VW_TABLE

  AS

  SELECT * FROM

  (SELECT TRIM (MAX (TABLE_NAME)) FROM ALL_TABLES WHERE TABLE_NAME LIKE 'POL_LINK %' AND OWNER = 'ACTUARYD')

  );

  Can anyone help? Thank you in advance.

  Most approach simple and straight forward it would be to recreate every month a CURRENT_TABLE view or a synonym that points to a table 'current' - table_2010401 or table_20140301.

  You can recreate this view, or synonym every month just after creating the table current.

  Another approach would be to create a view based on a function of pipeline that derives from a necessary table name and uses dynamic SQL statements to get the lines of him to channel them in the view.

• Only of first line of the dynamic table records in pdf format

  Please help me with this.  I have a dynamic array in an xdp which can be transformed by adding lines (called the details).  It seems to work in the browser, when I edit.  However, when I save as pdf, saves only the top line.  No idea why the entire table is not save the PDF?  Thanks in advance.

  I compared files markup of the xdp to form that works and one that does not.  I found that there is a line named templateDesigner expand {BTW dough doesn't seem to work in this window here, which is irritating}.  In any case, the form that did not work, it was 0 and in those who worked it is 1, so I guess that's why.

  I wanted that are correlated with a checkbox in the hierarchy of the Adobe Livecycle Designer GUI, but I would not again and now I have other projects to work on.  However, I hope this will help others with this problem.

  If anyone knows where the checkbox for this is the hierarchy in Adobe Livecycle architects, thanks for posting here.

  I used the tool of comparison was SVN diff, which opens WinMerge if installed on your machine.  The two form of work in a * powerful * tool of comparison.

  Of course, the xdp editing can be very risky, so be careful if you go this route.

  Thank you!

• Hide the items in the menu table of contents

  How can I do? The only way I know to leave items on the menu of the table of contents should mark them as ads.

  Which is the way to do it or there at - it another way to solve my problem?
