• How to read continuously from the rs232?

  Hello

  I'm new to LabVIEW and my questions would be obvious for some for you. So please help if you know the solution.

  It's for my school project. For your information, we need to schedule a Committee of Altera DE2 to control traffic lights (something like that) and at the same time, the Commission shall forward the States of enlightenment to a computer with LabVIEW installed via an RS-232 cable.

  The rest of the project was fine except for the part of LabVIEW, because as I said earlier, I'm new to LabVIEW.

  We use the "basic series write and Read.vi" in the folder examples of NEITHER. The problem is that we do not know how to change the vi in order to receive the data that come the DE2 Board permanently. Each time, the vi stops reading after receiving 24 bytes of data.

  So, the first question is:
  1.) how to read continuously from the RS-232 port? (We tried to use while "loop" but without success, maybe we were doing it the wrong way.) If you know the solution, please enlighten us for us in a detailed manner.

  (2) Secondly, once we have received the 'chain', how can convert us to bits (0 and 1) so that we might be able to manipulate the bits, for example turn on the LEDs that correspond to the bits.

  Thank you.

  Instead of reading the bytes of the port so to read that many bytes (which may be zero), just do a VISA read for 1 byte.  He will wait for this next byte.

  To get an array of Boolean out of this byte, use this code.  He turns the characters into a byte array.  Takes the first and the only element of this array, and then converts this single U8 number into an array of bytes.

• Cannot insert field or paste into the existing local Variable (Boolean container)

  Cannot insert field or paste into the existing local Variable (Boolean container)...  TestStand 4.1.

  It is very strange, especially since I've done it before.

  'Paste' and "insert field" selections are grayed out and disabled in the context menu.  I tried everything I could imagine and tried various combinations of positions.  I'm sure it's something simple, bu redicoulously, I can't find the redicule to solve this annoying problem issue.

  The local variable is a container of Boolean.  It has 90 elements and I need to add one more.  I can not change / rename or do something with this Local.  Must be karma (for those who know me in the LabVIEW forum).  Usually, you do a right click, insert field and that's where...  Not this one...

  Anyone seen this before?  Closing and re-opening TestStand doesn't change anything.  There is a collection in LabVIEW that feeds the local section in TestStand.

  It is a container of data custm type.  To change flags are ok (edit is allowed).  Can't think of any other valuable information...

  He finds...

  It should be edited in the Data Types...  It was not automatic after reloading the prototype of LabVIEW.

  I knew it was something stupid that I didn't...  I became close... but had not sought far enough.

  I was looking at the range of Types, but not in the file of the sequence...

  

• How to read data from a QVariant

  I have a multi select list, and I need to get a list of the people selected.

  QML

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

  {To ListView
  ID: lv_ingredients
  horizontalAlignment: HorizontalAlignment.Fill

  dataModel: _app.ingredientDataModel

  multiSelectAction: {MultiSelectActionItem}
  }

  {multiSelectHandler}
  actions:]
  Add the actions that must appear in the context menu
  When the multiple selection mode
  {ActionItem}
  Title: "search people".
  onTriggered: {}
  _APP.search (lv_people.selectionList ());
  }
  },

  ....

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

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

  Search in _app method:

  void classname::search (const QVariantList & list)

  {

  QVariant nlist = personDataModel-> data (list.at (0) .toList ()); //
  qDebug()< "list:="" "=""><>
  }

  ----------------------------------------------------
  Results in

  List: QVariant (QObject *, Person (0x857c310))

  That means I can see this list of Person objects, but I have no way to read! How can I get this picture out of the QVariant?

  Hello

  The code looks OK, but the variables are named confusedly.

  QVariant tlist = personDataModel->data(list.at(0).toList());
  

  This line actually returns a first person in the selection list. Where none have been selected,. at() function throws an exception and the application will crash.

  Row is a list of section number, line, etc. Data() method returns a single object for a given row.

  QVariant is a type that can wrap any primitive type, a map, a list or a QObject. It can also wrap pointers to custom classes derived from QObject declared using Q_DECLARE_METATYPE. More details on this here (Qt 5 docs it's should apply as well to Qt 4.8):

  http://Qt-project.org/doc/Qt-5.0/QtCore/qmetatype.html#Q_DECLARE_METATYPE

  Line that you use for the conversion to the person seems correct. To retrieve all people (untested code, but it work, I divide it into several lines for simplicity):

  foreach (QVariant indexPathV, list)
  {
    QVariantList indexPath = indexPathV.toList();
    QVariant personV = personDataModel->data(indexPath);
    Person *person = personV.value();
  }
  

  In the .h file where the person is found make sure you declare metatype its pointer, otherwise that it cannot be used in QVariant except flows manually to / of QObject, which isn't practical:

  class Person: public QObject
  {
    .............
  }
  
  Q_DECLARE_METATYPE(Person *);
  

  Also, I suspect that there could be something wrong with dataModel. If the above does not work, please copy - paste the header file where it is declared.

  If there are compilation errors, please paste entirely including context around them, it could also give us some tips.

  UPD. qobject_cast can be used to cast QObject * to another type (returns NULL if impossible), but is not going to extract a value from QVariant. Use of QVariant .value<>() function instead.

  QObject *x;
  ...
  MyType *y = qobject_cast(x);
  if (y)
  {
     y->...
  }
  

  ...

  QVariant v;
  ...
  MyType *t = v.value();

• How to return values from the record following instead of in the same record in LOV

  Hi all

  I use Forms 10 G.

  I have a block of details. In what in the 3rd column, I have a LOV.

  My requirement is let say I asked for it from the 1st and 2nd column, and it shows 1 record.

  After that if I pressed F9, then it should display the LOV list and, when I select a value any then it will create a new record with the same value of 1st and 2nd column.

  Example: -.

  Agenda	provider	country
  123	ABC	India

  We here in the column 'Country' LOV. Then when I pressed F9 then Lov should be displayed.

  as below.

  List of countries
  India
  U.S..
  Japan

  It works very well so far.

  Now if I select from the USA in the list then it should create a new record with the values of 1st and 2nd column.

  Agenda	provider	country
  123	ABC	India
  123	ABC	Japan

  How can I do this?

  Besically I need, rather than return the value in the same record, he must return to the next with the exsiting values record.

  The algorithm is:

  -use the KEY-LISTVAL about to 'COUNTRIES '.

  -LOV execution using builtin show_lov

  -store the return value Lov any parameter or a local variable in your trigger code ( vL_dummy_Deger varchar2 (100); )

  -Create registration

  -assign value to any new item you want to

  code like this:

  declare

  vLDummy boolean;

  vL_dummy_Deger varchar2 (100);

  Start

  -lov runs lov ruturns value is assigned to all the dummy elements to store Lov, return value. (no need to display)

  "-" DUMMY "point lets store lov, return value.

  vLDummy: = show_lov ('LOV_ULKE');

  --

  vL_dummy_Deger: =: model;

  create_record;

  : new_item: = vL_dummy_Deger;

  end;

• How to pass values from one form to the other setting

  Hello

• How to retrieve information from the appellant in BPEL

  I have a SOA - BPEL process that is consumed by the different systems. Purposes of registration, I need to retrieve the host name of the appellant for each request.

  Consumers are not cross any additional headers or special settings of WS-addressing.

  Since the BPEL process knows how to call back in an asynchronous call, I believe firmly that the caller information should be stored somewhere on the server.

  So please let me know if anyone has any idea on this.

  Thank you

  Helene.

  Hi Helen,

  you could try this - get the value of the header property transport.http.remoteAddress and assign it to a variable. To do this, in your activity. More details on how get/set header values can be found here - https://docs.oracle.com/middleware/1213/soasuite/develop-soa/GUID-33A38C1A-38A6-473B-9FEA-D3164AD7A118.htm#SOASE20757. Double click on your activity and go to the 'Properties' tab add the transport.http.remoteAddress and assign it to the existing variable.

  HTH,

  A.
