• How to read data in Adobe Flash and align it to look like it's column?

  I am doing an application that already exists, but I add a few improvements. I'll explain what this app is. There is a server and client side. The client side adds data to the Access database (the columns are time, name and surname). On the other computer is an application that displays this data (I don't know if he reads a database or another type of file, but I did a database). I know that server-side plays an .swf Flash file. This screen stays for about 30 seconds and then the application plays videos in the video player installed (ads, this model is connected to a TV) for some time and then the screen goes back to the display of the data.

  I'm 18 and I have very limited knowledge of Adobe Flash (I learned something at school). I've done completely client-side app. I now how to create server-side. My main problems are: how to connect to Adobe Flash to the database (is it possible to transfer this data to any other file that can be connected to the Flash?), how to read data from database for Flash and how to display it. I don't want to display the data in the grid. In the application that already exists, each word is like a new text (tool in Flash) and it is aligned. Is it possible to add a loop that creates new texts and plays database cell? How to refresh the Flash screen?

  I know it's a very complex issue, but your help would be very appreciated. I did on the client side in Delphi. If you need more information or if you do not understand something of my explanation, don't bother to ask. Thank you!

  You can transfer data back and forth between Flash and database on a server with PHP as the intermediary.  If you are looking for Gioogle use terms like 'AS # PHP MySQL tutorial' (fillin 2 or 3 for the ' # '), you should be able to find something to help you along there.

  What about adding new textfields and harmonizing, it depends on what version of as you use.  In AS3, you use just...

  var tField = new TextField();

  tField.x = a value to match.

  addChild (tField)

  As far as refreshing goes, this would require removing all Textfields you added and re-create new ones like you did the first time.  Yet once, it depends AS version that you use.  In AS3, you can use removeChild()

  Hi hand hunter.

  If you have PDF attachment with your email and you use windows.

• How to read data from OM - 62 temperature/humidity data logger in LabVIEW?

  Hello

  I have an Omega OM-62 temperature/humidity data logger I want to communicate (initialize recording, reading/writing data, stop recording) through LabVIEW 8.6. The OM-62 is connected to the PC via a type B USB-miniUSB connector, and I have provided "Omega Recorder program Interface" on my Windows operating system. I called online DAQ support Omega but I was told that data recorders low level like this have not provided capabilities of LabVIEW, which I fully understand.

  My question is why I have to use their program to communicate to this device? If I knew the syntax program them used to connect to the device, why can't I use through VISA? Do I need to build my own LabVIEW driver from their supplied driver?

  Python is easier to apply to this scenario solution?

  How can I see the code "Omega Interface Progam recorder" on my Windows operating system is using to communicate with the OM - 62 sensor?

  I just want to know how this could or could not work because I think I'm missing some concept in my understanding of programming LabVIEW/novice. It would be easier to run my LabVIEW program and their program at the same time, but I just want to understand it at a deeper level.

  Curosity killed the engineer occupation,

  P.S. I have attached a few driver configuration information, but I have no idea if this is useful.

  Unless the manufacturer provides a kind of programming interface or API to communicate with the device that you have trouble with your own software interface to it whether LabVIEW or Python or something else. This could be in the form of a driver dll, Protocol series modbus (etc. etc. etc.).

  If it is not condition / available and you really need to communicate with the device, you will need to look at using something like a sniffer USB/driver (software? hardware?) to try to intercept communications between their software and the device. You can then use this information to try to understand what the commands it sends and the responses received and how to convert data.

  Once you have that until now... I don't know what options are willing LabVIEW for control of USB device, but a proposal, I would say that you would need either a driver USB low level or you have to write your own driver in another language and that call from LabVIEW.

• How to open .dat WP51 with Vista?

  I have Windows Vista, and it should be up to date.

  I need to access two WP51 documents that were sent to me.  We got a .dat extension, and the other has an extension .read.

  I was prompted to "set associations...". "but when I went to the appropriate place to do this, nor read extensions or .dat generated on the long list of extensions on the page"associate a file type... ". ».

  It is essential that I have access to these documents.  I can't find anything when I googled "How to open .dat wp51" (except odd links to pages of pirate...)

  If anyone can help, I'd appreciate it.  Please keep your instructions as lay people as possible.

  Hi AnnieElle,

  Looks like there are two parts to your question:

  (1) open a file read:

  Just to clarify, you have tried to open the file read extension in a text file? (Opening the .dat file perfect word would fail to open as a .txt file)

  (2) open a WordPerfect file with .dat extension:

  Basically, the idea would be to open the file in WordPerfect or open it in a word perfect reader. It would be really better to know which version of this file may have been because they have different extensions depending on the version of Word Perfect.

  Reference (for more information on what file extension fit the WP version the .dat file came from):

  http://en.Wikipedia.org/wiki/WordPerfect

  How do you get the file to read at this point would be to change to the extension of the WP program it has been generated to go and then open the form in WordPerfect format or Word Perfect player. For example, to change the .dat by .wp extension and open it.

  If it does not, the file is of a type, we cannot recognize or likely unreadable or corrupted.

  Hope this helps,

• In CloverETL how to read file xlsx with a column of type "long".

  Hi all

  Let me know how to read an xlsx (Excel) file with columns of data type "long".

  I used XLSDataReader to read file xlsx. There are names of "Remarks" column, which exceeds the linits of 256 characters, so I can not use type 'string' to do this.

  IM using "long" datatype and graph below error crossings.

  Pointers on this will be greatly appreciated.

  I think the 256 character limit is a red herring.  All data is there, the front-end integrator is truncating only for display purposes.

  Your data is a string, it should certainly be classified as a string in the metadata.  For a long time is for numeric values.

  I don't think there is a problem here, if you were to write this data to the trash or a text file (after reading it in), you will see that your data is not truncated.

• How to read data from the drop-down list

  Hi all

  I use this to display a drop-down list.

  inputScreen.add (new NumericChoiceField ("number of objects:", iStartAt, iEndAt, iIncrement, iSetTo));

  How to read the data selected by the user? say if my list contains from Monday to Saturday, how will I know what day selected by the user? and how that store in the variable? Thank you.

  You have your data in a table and this stone he is used to populate the ObjectChoiceField. The FieldChanged listener you can obtain what the iteme selected to help index:

  int index = yourObjectChoiceField.getSelectedIndex ();

  and for the use of the object:

  Bean of MyObject = myObjectArray [index]

• How to use Data Guard with E-Business Suite

  Hello

  I'm trying to get my head around how would you use Data Guard with E - Business Suite.

  I know that you can use only physical standby with EBS, however I have a few basic questions about specific values < SETTING > and how they are treated by a standby.

  Given that the standby and primary servers will have different host names and that generally there are < FRAME > specific values that include the hostname, where they will have to change on the standby server, both from the point of view of the battery backup Apps and within the standby database itself, I wondered how it would happen.

  Usually, EBS cloning process would change the < FRAME > target settings in the target apps stack and the target database (for example, parameters such as FND_NODES etc.).

  Q1. However I do not know how the process of cloning E - Biz would fit with a database of the day before?

  Q2. As the standby database won't even be in an open State, I don't know yet how you would apply a party any of the cloning process to a database of pending to the target?

  Q3. Even if you were able to change on the eve of the database to reflect the < FRAME > from backup server, it would mean surely it was more a physical copy of the primary database, that's why it would be more a day before.

  All a bit confusing - any clarification appreciated

• Read data series and detect the break in series at the same time

  I need to communicate with a serial device that sends messages back, but also sends a break, break, break, break series combo that I need to listen to. I've never worked with before series breaks but the only VI I found which seems to detect pending VISA on event VI with the series Break parameter. I'm not sure that understand how I could detect a break in the series, but also to be reading and writing messages at the same time in the meantime. Isn't this possible?

  If you use multiple loops, I think you can do.  You use 1 loop to check to see if there is data and 1 loop looking for breaks series.  Then use queues, authors of notifications or events to anyone who needs to know what you have experienced.

• What is the best way to read data series high speed?

  My goal is to read 14 bytes of binary data of an instrument on the serial RS232 (460800 baud) to 2000 Hz. I didn't get a card series high speed again so I am currently using the standard serial port (115200 baud) and reading at 400 Hz I have configure the port series, empty the buffer, and then enter a while loop to read incoming data. I have a visa 14 bytes read by interation seconds 0.0025 (400 Hz). However it seems that the sensor is spewing data faster that labview can read because the bytes are accumilating in the port. After some time the buffer fills and the program fails.

  Is there a better way to do it?

  Would it not be better to read the larger quantities of data less often, for example as 1400 bytes every 0.25 seconds?

  Thank you

  Hello

  I think it would be good to read several points in a loop, and keep the loop less than 1000 Hz.  I found in the past, have something to run faster than about 10ms tends to fall down when windows loses interest in the process.  So yes, choose the slower you can get away with reading samples - for example to read every 10ms and read 20 samples every time. You should be able to configure your serial port in order to buffer the samples that I guess.

  Also and the issue of windows - if you use a loop "timed" instead of a while loop, so you can force it to an integer value including the ms.  You can also assign a dedicated processor and set the priority to 100, which means that it is less likely to elapse and decide to scan your hard drive for viruses or consult your account e-mail or what he does when he's bored with your program.  Also it "' tells you if the loop has taken longer that planned to run - you can use this to help iron out bugs etc. - report and/or to the user if you missed a few samples.

• 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();
