• Code example for single asynchronous reading of multiple waveforms

  Hello

  I looked around but have not been able to find the code example for single asynchronous reading of multiple waveforms.  Could someone point me in the right direction?

  Thank you

  Dale

  Hi Dale,

  Have you looked at the code using .NET Framework DAQmx example? It shows this code:

  class DAQmxAsyncRead
  {
  private AnalogSingleChannelReader reader = null;

  public DAQmxAsyncRead (task t)
  {
  Create the drive
  Reader = new AnalogSingleChannelReader (t.Stream);
  Acquire 100 samples
  Handful of IAsyncResult = reader. BeginReadMultiSample (100, New AsyncCallback (OnDataReady), null);
  }

  Public Sub OnDataReady (IAsyncResult i)
  {
  Recover data that has been read.
  At this point, all that occurred during the asynchronous read exceptions are thrown
  Double data = reader. EndReadMultiSample (i);

  You can call the method BeginReadMultiSample here once again
  }
  }

  In addition, this article: http://digital.ni.com/public.nsf/allkb/485201B647950BF886257537006CEB89?OpenDocument talk about different causes of the reserved resource error.

• Complete code example Widget push?

  Some body knows if there are some complete code example push Widgets, with subscription, unsubscribe, background, Service Push BlackBerry...?

  I'm looking and only found parts, not a complete example.

  Thanks in advance

  Not a complete example, but here's my JavaScript to push functionality.

  var port = 201;
  ...
  function subscribe() {
     blackberry.push.openPushListener(handleReturnData,port);
  }
  
  function handleReturnData(data) {
     var wasBackground = false;
     if (!blackberry.app.isForeground) {
        wasBackground=true;
        blackberry.app.requestForeground();
     }
     if (data!==null) {
        var text = blackberry.utils.blobToString(data.payload);
        ...
        //do some work with text
        ...
     }
  
     if (wasBackground)
        blackberry.app.requestBackground();
  }
  
  function unsubscribe() {
     blackberry.push.closePushListener(port);
  }
  

  also...

  function init() {
     ...
     blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_BACK,sendToBackground);
     blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_ENDCALL,sendToBackground);
     blackberry.app.event.onExit(unsubscribe);
  }
  
  function sendToBackground() {
     blackberry.app.requestBackground();
  }
  

  stick that in a js file and call init() and subscribe() in the 'onLoad' of your HTML page, you should get close to a working example. Up some alerts in the handeReturnedData function to see what pushed you.

• RichList code example does not

  I tried to use the code example provided for the RichList UI component, but it did not work. I get illegalStateException or another similar error. I didn't with my richlist photos so I changed it to look like this:

  List of RichList =

  new RichList (getMainManager (), false, 1, 1);

  List.Add)

  new Object [] {"Device 1"});

  BTW, when I copied and tried the unmodified original code, it didn't always work (I got the photos stored in the folder too and still did not work)

  If anyone can explan the parameters to the constructor in plain English he could really help me, thanks.

  Nevermind, I solved it. I had to add super(Manager,NO_VERTICAL_SCROLL) to the upper part of the constructor, and then I had to change the bitmap to bitmapfield and set it like this:

  BitmapField bmp = new BitmapField (Bitmap.getBitmapResource ("pic.png"))

  When I used just bitmap he says illegalstateexception and says that I can only use channels, fields and images bitmap, but bitmaps don't work lol.

• CS6 AI install - code example may not run correctly

  Hello

  I have problem in execution of the code examples in the CS6.

  I have install AI CS6 and download the SDK for AI CS6. I'm building the code sample of the plugin (tutorial, webter). I build success, but this program does not work in CS6.

  With the tutorial. It is apprirance in the Help menu and object menu-> filter-> SDK-> tutorial. But no action when I click on it

  With webter. It is apprirance in the Help menu and the menu window-> SDK-> webter. But no action when I click on it

  My Os is XP SP3 windown.

  I build with visual studio 10.

  I can build successful plugin code example in the CS5 SDK and run successful with AI CS5.

  You have the same problem?

  Hi Hehiha,

  I think because you have menu items appearing as side C++ example must be run properly. However, these two samples use an extension flash to provide the user interface, which is something that has changed between CS5 and CS6 SDK. If extensions that provide this Interface were not installed or running using Extension Builder, then I would expect that it causes the behavior you are experiencing.

  To install the extensions to confirm that this solves the problem, you can do the following:

  If you look in the TutorialUI or WebterUI folders, you should see an output with TutorialUI.zxp or WebterUI.zxp folder if you double-click the files, they should open the extension manager and install the extension.

  If you restart Illustrator, and try the plugins I would expect now to display a Panel after clicking on the menu items. This is if the problem is that I have described.

  I hope this helps,

  Thank you

• VBAI 2013 API c# code example

  I try to use a new model player NOR SmartCAM VBAI 2013 - previously we have used VBAI 2009 API - and connect, inspect, and achieve results (specifically ID matrix read and pass the status).

  The c# code sample uses VBAIEngine object.  Not clear how to connect to the camera.  An example that I can operate with the camera would help enormously.

  I'm sorry. There is no chm or online documentation for the API .NET VBAI. We currently provide some examples.

  The API is relatively easy to use, and the examples provided with VBAI show how to use most of the functions.

  For the complete list of functions and their prototype, double-click the NationalInstruments.VBAI.200x reference in the sample project, to see the Assembly in Object Explorer.

  From there on, tyou can extend NationalInstruments.VBAI, click on VBAIEngine and see the list of all methods and their prototypes in the window.

  Same for NationalInstruments.VBAI.Enums and NationalInstruments.VBAI.Structures.

  Sorry I don't have a better answer for now. If you have questions about some of the methods, feel free to post again on the forum.

  Best regards

• Why do I get error 200524 for the generating function 2 code example?

  I get the following error message:

  Error-200524 occurred at the generating function 2 channel_lv86.vi

  Possible reasons:

  Scripture cannot be performed because the number of data channels does not match number of channels in the task.

  When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

  Number of channels of task: 1
  Number of data channels : 2

  Task name: _unnamedTask

  When I downloaded and ran the 2 channel here code: https://decibel.ni.com/content/docs/DOC-3545

  I have a card pci-e DAQ 6259 and a block BNC-2110

  Why I get this error?

  When I open the VI I selected ' Dev1/ao"under physical channels. I tried all the other options (a0 - a3) which gave the same error message.

  If you have 2 channels in your data (as indicated in the error message), then you must choose 2 channels in your task control (the error message says that you have selected only 1.)

  You saw in the example how they were able to identify the 2 channels of analog output?

• barecode code example

  I have a HP Laserjet P3015 with the police HG281US BareCode USB.

  Help, please

  > Do you think that code3of9 will support my 123456.12

  Code 3 of 9 sets 44 models of different symbol, which represents:

  • the numbers
  • Uppercase alphabetic characters
  • seven common symbols (including the character "comma".")
  • a Start/Stop character.

  Points on your sequence name:

  <27>* p500X <27>(0Y<27>(s0p4.69h12.0v0s0b0T * $JOB__ID$ *<13><10> ))

  • <27>is your representation of the character escape (the character of control code decimal code 27or hexadecimal 1B).
  • Your first sequence is to define an X coordinate (in units PCL), but not a y; you generally specify both; for example * p500x1400Y (a composite or complex sequence, containing two sequences with the same 'root').
  • I guess that your variable $JOB__ID$ contains only characters that are part of the Code 3 of 9 directory.
  • Your statement ends by <13><10> , which I assume are your representation of the two characters of code control CarriageReturn (hexadecimal 0 D) and newline (Hex 0a).
  • It is a little confusing sequences and the positioning of the cursor by using these control codes (of which the effect is based on the margin values left and current leading into force); I tend to use one or the other (preferably cursor positioning), not both.
  • Ensure that the following work-ID value is only PCL codes control, or escape sequences, not data, otherwise that additional data will be assumed to require in the current font (bar code); so, once you have written the barcode data, select a different font (text).

• The unnecessary use of synchronize in code example in the Dev Guide

  I ask this question with some trepidation, I'm sure someone out there will be able to explain it and then I'll feel really stupid asking.  But that's...

  Using a HTTP connection code sample in the developer's Guide (I checked 4.3 and 4.5, and it's the same in these two levels), use synchronized in two places that I don't understand.

  (1) getUrl() - Code follows

  /**
  * Retrieve the URL. The synchronized keyword ensures that one
  * thread at a time can call this method on a ConnectionThread object.
  */
  public synchronized String getUrl() {}
  Return _theUrl;
  }

  I understand the comment, and it is sometimes useful force methods you want to synchronize.  But not this method in vessel closed.  If anything, there are more cases of use of this mechanism for the recovery method in this code.

  (2) around of the fetch block - following Code:

  / * Make sure that pull requests are not missed
  * While the received data is processed.
  */
  {Synchronized (this)}
  Open the connection

  When I see a synchronization block like that, I guess it's a little shared code that can be executed by multiple threads, which this clearly isn't.  So why is it synchronized?

  In fact, I think that 'design' is a testament to this example may be imperfect.  I think it would be better to have a new Thread for each connection, or have a queue (synchronized) URL addressing.

  As evidenced by another thread on this forum, the developers make these samples as Gospel and try to use them.  So if this is wrong, perhaps we could fix.  But maybe it just me being a lumberjack full.  Wouldn't be the first time...  And won't be the last!

  It seems that this example has been designed with a base defense to the following (if no synchronization) scenario:

  Event thread request _start = true.

  Threaded starts the connection.

  Event thread again pray _start = true.

  Threaded end connection, defines _start = false.

  Net result: the second event thread request is not met.

  That being said, the guys are right: this design is mediocre at best.  In the scenario above, the second request of event thread is blocked while the thread of the connection ends... and as everyone knows at this point, blocking the event thread usually leads to a world of pain.  There are certainly better approaches that can be used here, and probably the easiest way to this problem is just to have the best control flow, such as not allowing not a new connection request while one is already underway.  Certainly the synchronization adds excessive complexity to this problem and distracts from what the sample is trying to demonstrate: a simple HTTP connection.

  For this example, and the extraction, I will recommend to the authors that both be reviewed and be a structure such that these samples are as simple as possible.  Thanks to Peter marchywka for their suggestions.  Comments like yours, it's how we identify areas for improvement.

• Where can I find the code example to download...

  At one point there is by setting my BB with Eclipse dev environment, several months I had stumbled on a link where you can download some sample code. It includes items such as the demo of socket and a little more.

  I have looked at the links at the top of the forum and cannot find this link. It might be good to display in the header of the forum with others, unless I'm completely blind and missed.

  Anyone got the link to examples of BB code?

  Thank you.

  I use Eclipse for development - using the plugin. I had not thought looking in the directories of the plugin to find the source code. It's a bit unexpected.
