• Error data truncated when loading saves waveforms

  Once I recorded a waveform using the 'write waveforms in a file' VI (for example I save it as wave.lvm), I tried to load it using the VI "waveform reading a file. I always get an error about not flattened or truncated data (error 116). Any suggestions?

  Hello boomchild06,

  After having had a detailed look at the various databases that we use, I discovered that it is a known issue with LabVIEW 8.0.

  Workaround was proposed as follows:

  1. place the waveform of File.vi reading on the block diagram and double-click it to open it.
  2. go to the diagram and click twice on the Open create replace WDT DLog File.vi and discovers the block diagram.
  3. navigate into the structures of the case until you see the service to deny access. I suggest you save this VI as something different from this moment on, so that you do not change the screw in the vi.lib folder.
  4. Once you have the re-recorded with a different name, and I would say in a different location, follow the exit of the bunch of the error in the structure of the case that it is connected to. I navigate to the case of fake and then made a right click on the border to eliminate the species.
  5. Once this is done, you can remove the whole box structure. I could recommend this way to avoid a lot of painful rewiring.
  6. Once you have removed, you can remove any broken wires, unbundle function and the function is equal to zero. You can either choose to disable the feature to deny access, to avoid error pop ups.

  Alternatively, the fix has been implemented in LabVIEW 8.0.1 update which is a free patch that can be installed. If you want to go ahead and install this, it can be downloaded from:

• 16 lines of data, truncated to 1 line of data?

  Alright my program generates a data of 16 lines, as shown below, and here is the block diagram.

  

  

  what I need, is to generate a data with 1 single line drawn below.

  

  I think the problem is due to the analog digital conversion but I think that it is the more significant method. It would be great if I can truncate to 1 line because it's essentially the same thing.

  I have also attached my VI if it would be more help. Thanks in advance, this wall that I'm running into is annoying me.

  lol sorry I thought about it again later.

  EXTREMELY simple

  you need to just create a constant on the 'resolution' from analog to digital and set it on however, many bits (in my case 1)

  Thank you!

  This is the function I'm using to display the QML it is called from main.qml and works correctly.

  void PeopleFinder::onSearchClicked() {
      qDebug() << "PeopleFinder::PeopleFinder::onSearchClicked::\t" << "begin";
      qDebug() << "PeopleFinder::PeopleFinder::onSearchClicked::\tfname:"
              << m_fname << "\tlname:" << m_lname;
  
      // Create a network access manager and connect a custom slot to its
      // finished signal
      mNetworkAccessManager = new QNetworkAccessManager(this);
  
      // create a data model with sorting keys for lastname and firstname
      Q_ASSERT(
              connect(mNetworkAccessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(requestFinished(QNetworkReply*))));
  
      //Load the bew QML file of Search from here
      QmlDocument *qml = QmlDocument::create("asset:///SearchResults.qml").parent(
              this);
      qml->setContextProperty("peoplefinder", this);
  
      Page *mypage = qml->createRootObject();
      qml->setParent(mypage);
      qDebug() << "PeopleFinder::PeopleFinder::onSearchClicked::\t s444444";
  
      // Retrieve the activity indicator from QML so that we can start
      // and stop it from C++
  //  mActivityIndicator = mypage->findChild("myIndicator");
  
      // Retrieve the list so we can set the data model on it once
      // we retrieve it
      mListView = mypage->findChild("resultlist");
  
      mNavigator->push(mypage);
  }
  

  Once the page loads in the QML it call the launch request providing c ++ file and once the
  query is completed under function is called with the data. I checked that data are downloaded properly

  void PeopleFinder::requestFinished(QNetworkReply* reply) {
      qDebug() << "PeopleFinder::PeopleFinder::requestFinished::\t"
              << "response received";

          qDebug() << "\n" << reply->errorString();
      }
  }
  

  But now, the real problem begins as in how to convert QByteArray data type of QVariantList which can be loaded into the datamodel
  I don't want to write the data to the XML file and then pass that as a list his will is very slow, once I move test environment to the production environment.

• http data view connection

  Hi I want to achieve paging as a concept in the bb device. I want that demand is expected to go to first on the server and the data will be displayed in the field from the list. but when the user comes to the last record in the listfield demand should still communicate with the server and put the following Recordset? I have no idea how to start thinking about this problem. I am able to communicate with the server and the data, but how do I optimize the paging like thing. also where can I keep the record during the second request goes to the server.

• BlackBerry smartphone data truncated during synchronization - the note field size can be increased?

  I find that some data is truncated on the "BOLD" when my "BOLD" with Outlook synchronization. This is a problem for some of my bigger contact and entries of calendar notes.

  Is it possible to increase the size of these fields on the device must match which allows Outlook (or at all)?

  ... Thank you!

  It turned out that only some 200 entries truncated calendar had an atttachment, but some appeared to have a symbol (small rectangle) character that seems to replace a in the subject line. In my opinion, that they were introduced during a synchronized using an earlier version of Desktop Manager when I was with a Blackberry 8700.

  Re: problem of truncation: when syncing with the "BOLD", I discovered that in each case that a few words at most have been lost from the entries, regardless of the initial term. When I took the time to check them individually, most were not serious for me.

  Then... I still don't understand why it happened, but I was able to fix the problem for now.

• Data truncation error ORA-12899 ODI File_To_RT: value too large for colum

  Hello
  Give me an idea so I can truncate the grater data source to length max before you insert into the target table.
  
  Prtoblem details: -.
  
  For my script read the data of the insert and the source .txt file the data in the length of the target table.suppose source file data exceeds the length of col max of the target table. So how I truncates the data so that the data migration will be successful and also can avoid the mistake of ODI "" ORA-12899: value too large for column '. "
  
  Thank you
  Sébastien

  I was referring to the source database. Because C$ table is created based pon the source data store. Increase the physical and logical length on a same value.
  If you see the code generated for C$ table create table step you can see the size of the column. This table is not able to store the incoming string value.

  Substr function will be used when the data will be loaded either I$ table or table target.

• OSMF with HTTP data stream search resets the starting index...

  Hello

  I built an OSMF player that allows users to get to where they were during the recovery, but also to rub at the beginning.

  FOR EXAMPLE:

  A flow is 1 minute.

  The user starts playing in 25 seconds.

  The user can rub-5 seconds or transmit to 55 seconds.

  It works perfectly with RTMP - TimeTrait reports correctly and video is displayed correctly.

  FOR EXAMPLE:

  Start at 25 seconds, TimeTrait reports: duration = 60, current position = 25 and video display is 25.

  Seek to rewinds 5 seconds to the current duration = 60, position = 5, video display is 5.

  But...

  With the HTTP stream...

  Start at 25 seconds. TimeTrait reports: duration = 60, current position = 25 and video display is 50.

  Search rewinds 5 seconds before the beginning of the stream and give me a media full... end of the stream.

  Start at 30 seconds, TimeTrait reports length = 60, current position = 30 and the video display is 60 Yes give me a media full... end of the stream.

  It is quite clear that what is happening is that search HTTP stream reset my starting index to the point of looking as if I had started to play with:

  NetStream.play (seekPoint);

  Rather than:

  NetStream.play();

  NetStream.seek (seekPoint);

  This, I hasten to add, is a terrible problem from the point of view of my client because it means actually I can't resume content.

  Does anyone have ideas, workarounds?

  G

  After digging in OSMF code I found a SOLUTION:

  First of all, make sure you have the latest OSMF source inside your project.

  For now it is 2.0.71 (org.osmf.utils.Version).

  Go to org.osmf.net.httpstreaming.HTTPNetStream

  and make a few changes:

  1 change the line # 1441

  _initialTime = _dvrInfo! = null? _dvrInfo.StartTime: currentTime;

  TO
  

  _initialTime = _dvrInfo! = null? _dvrInfo.StartTime: (_seekTime > 0? _playStart: currentTime);

  2. change the line # 1496

  _initialTime = currentTime

  TO

  _initialTime = _seekTime > 0? _playStart: currentTime

  That's all!

  Now you can listen to MediaPlayerCapabilityChangeEvent.CAN_SEEK_CHANGE event

  and immediately.

  By the way: If you're going to find all the bugs related to this change feel free to post them here!

• InputStreams for HTTP [S] response data: confirm a minimum memory buffer/reading early?

  I need to manage data from a web service response. The format of the response data is under my control and is returned as a stream (net.rim.device.api.crypto.tls.TLSInputStream) to my BlackBerry application. The content of the feed is an XML stream that contains simple header information and then one or more 'chunks' of data. The data is compressed (gzip) and coded (Base64). BB app must decrypt, decompress, and then process the data in the stream. For the purposes of my application, I never need all of the data at a time; processing flow for real, that's what I'm looking for. I've implemented a pipe which, in pseudocode, looks like this:

  SecureConnection httpsConn; already implemented

  InputStream httpsStream = httpsConn.openInputStream ();

  InputStream compressedStream = new (Base64InputStream.decode (httpsStream));

  InputStream is = new GZIPInputStream (compressedStream);

  int aByte = is.read ();

  The goal is to put buffer in the bit data as possible so that the operation on the side of BB is not intensive memory as the data grows. The effective implementation of this pseudo code works very well.

  The question I have is: I can confirm that the httpsStream I have created from the httpsConn is completely not himself read the BB in the specific RIM code? In other words, if there are 20 MB of data in the stream, I don't want to know that the stream has read data HTTPS completely - 20 MB all - and then put at disposal. Instead, I want to know only as much data is consumed as I makes (is.read) as well as a small buffer, perhaps, for the effectiveness of the network. A third way to ask the question: I think that it is supposed to be the definition of a well implemented InputStream, but I'm having a hard time finding a definitive '' Yes, J2ME (or BB) InputStreams promise to read HTTPS data on request and not all at once.

  I expect tons of streaming audio and video apps are partial evidence that works real data on the fly on the Net.  Still, I left the details as XML processing by SAX - it's one on the behavior of the InputStream HTTP [S].  But it brings the fourth way to phrase my question: if I use SAX instead of a tool of DOM to treat my HTML because I want to monitor the pressures of large data flows, will I get cancelled by buffering I can't control in the low-level InputStream HTTP [S]?

  Before you say, ' HTTP [S] is not where you should make streaming ", this is not streaming in itself. It is instead one - possibly large - answer to a POST.  Highly 'typical' web interaction

  If changes in response based on the version of the OS, presumably 4.6 or better is the target platform.

  Thank you!

  -Del

  I don't remember the said documentation. All I remember is that I proposed of workaround to someone on this forum and they later confirmed that he has solved the problem of buffering (they were streaming audio as great answers HTTP - streaming started to work very well, without a lot of latency).

• data transfer labview to the web app server

  Community of LabView greetings!

  I have what I think, it's a simple question:

  How can we transfer (real-time) and store acquired data (e.g., time, temperature and so suite..) of a labview VI to a server over the internet so it can be used for a mobile application.

  Thanks in advance!

  You will need to your data in your LabVIEW application on a server:

  -Customer HTTP screws

  -TCP/IP

  -WebSockets

  Server might have a LV application on it, or you can use a web server with a scripting language (for example PHP/ASP/Node.js).

  You will need to write something on the server to listen to your LabVIEW application and contain the data :

  -Database

  -File

  -Memory

  You will need to write a few API/interface for push/recovery of data for example JSON/POST/XML - take a look at 'RESTful API.

  The choice of one of them to go for depends on how 'real time' you're talking about - how often you want to update data, latency, etc..

  If you don't want to do it all yourself, there are 3 third-party vendors that can store data in this way for you - there is a free (but limited) race one by SparkFun - https://data.sparkfun.com/ but I don't know there are other services.

• LabVIEW HTTP without PC (client) browser dedicated (as a server)

  The web server is already configured with success on the ATMEGA32 microcontroller.
  All I need is a functional GUI to any client on the internet to receive the data through the browser.
  The goal of this problem is to prevent any pc dedicated to this system. (for the purpose of Web or GUI server)
  Nature of data : data from current density and the temperature of the fuel cell.

  I would like to know your best solutions in this case!

  Thanks in advance!

  If you want to put a web browser in your VI, you can use the WebBrowser ActiveX component. If you want to read the HTTP data programmatically you can use HTTP Client on the screws in the Communication of data-> protocols-> HTTP Client to connect to the server (ATMEGA32) and read the data.

• signature of the oversized https request

  Hi, is it possible that we can trigger an alarm when an https request exceeds a certain size?

  I can define a type state.http signature using parameters such as the following? MaxRequestFieldLength takes into account the fragmentation of application data by ssl?

  -Direction = ToService

  -MaxRequestFieldLength = 1000000

  -servicePorts = 443

  -AlarmThrottle = FireOnce

  -MinHits = 1

  -ResetAfterIdle = 15

  -ThrottleInterval = 15

  -WantFlag = TRUE

  If this does not work, would you please suggest alternatives. Thank you.

  I looked into it, and it does not seem that this will really be feasible with the help of a personal signature. First, you must use the STRING. TCP engine for this. THE STATE. Engine HTTP needs context information in the HTTP stream in order to work properly. Because the HTTPS protocol is encrypted traffic, we have not these signals. So there's basically trying to count bytes in a HTTPS stream. Two problems here. First of all, the implementation of regex in STRING. TCP is limited to 512 ~ States for performance reasons. So, we will build only a model to 512 or more characters. This obviously does not follow the large desired patterns. Secondly, we need some sort of condition of single endpoint, a character model, at the end of the regex model with. Due to the random nature of characters in the encrypted HTTPS data, we do not have the guarantee that our terminator will not unexpectedly appear in the stream for giving us no good way to determine, we have reached the end of the search. This signature will probably be coded in a new engine.

• 4310G external Flash Data queue access

  Hi all

  I use a G 4310 with DMM (both on 5.4), and I'm trying to use an external data file to learn the dynamics, text, and image variables.

  If I use this configuration with a regular browser, it does not work unless I have add security exceptions that allow external data file access. Is this a possible cause for this works only not with the DMP? is there a part of the DMP that must be configured to allow this?

  For the test, I use to play HTML / Flash section available from loggind directly in the dmp via its IP address.

  I put the URL in as follows:

  Browser and Flash playback

  Reading URL: http://***:80/content/aa2683af-BC33-4A9F-8C00-f095754307a6.swf  

  Flash settings only

  Flash variable: Data_Url =http://***/***/***/data.txt

  I'm sure that's the right way to put those URL to, but the flash file fails to load dynamic content during playback on the DMP.

  Can anyone help with this?

  Thanks in advance!

  Luke.

  You may need to define a domain policy to allow your flash access and consume data hosted on a local server files. You can do this by placing an XML file called crossdomain.xml in the root of your web server. It should look like this:

  http://www.Adobe.com/XML/DTDs/cross-domain-policy.DTD">."

  In this case, we allow the access all areas using the generic specification, but you might want to restrict that.

  I hope this helps.
