• Fill a table from multiple threads

  Hello

  I tried to find the mechanism that I could use to fill an array of strings of multiple threads (a little and loops with different times, within a single process) in an asynchronous way.

  I went to create--> property/Invoke Nodes-> (...) but I could not find any properties/methods that I could use. Did I miss something?

  For example how programmatically insert item in array to the x position?

  I will use so semaphores or FGV would be enough?

• You bird 31 crashes when you reply to an e-mail from multiple threads

  I've updated to version 31 today. Since then, when replying to emails that have several threads (2 or 3 responses attached) the Send button hang up. If I wait long enough, or violin, it can go to the project. Why? What can I do to get this kind of threaded replies to send as an e-mail from original naked base?

  do not plug into something new, I asked if you had it that it sounded like you did. You asked what it was that has basically answered my question, but I have provided a link to answer your question of what is.

  I have no idea of what having 2 or 3 responses attached, I thought that the add-on could explain it. So does that mean?

  Disable e-mail analysis:-almost all of the programs anti-virus mail as well as falling out.

  No one else has reported the problem, so unless your ready to work through the process and exactly what it IS your destiny to never upgrade to a newer version. Never. The question is no longer not studied before by someone, unless you have be it resolved.

• Berkeley DB Java Edition - multiple threads accessing the database

  Hello
  
  I would like to access (read & write) a Berkeley DB of multiple threads (process/FMV anyway).
  
  Can I use a single com.sleepycat.je.Database object for all threads, or should I create an instance of each?
  
  Or is there another way to do it?
  
  Thank you

  The object database can be used by multiple threads, you can use a single instance or multiple ones, as suits you best. Of http://docs.oracle.com/cd/E17277_02/html/java/com/sleepycat/je/Database.html.

  The database handles are free of threads and can be used simultaneously by multiple threads. '

  If you read the javadoc, you can find any other comments on the use of the classes from multiple threads.

  Kind regards

• Problem with multiple threads

  I have a program that interacts with an ESX 3.5 server using the VIX API, written in c#. I'm from multiple threads in c# program with each thread running an automation process which creates a connection to a virtual machine on the ESX Server, some automated process, and then disconnects. I'm having problems with this. When I call Disconnect() from one of the threads, it seems to cause problems with my other son if they have not yet disconnected. I connect to an another VM on the server in each thread. The problem is if I don't call disconnect, I get errors, but if I call disconnect in a thread it causes errors. Y at - it something similar? Any suggestions on how to make this run smoothly? Thank you!

  This sounds a lot like you are getting hurt by the host sharing of handle.  If HostConnect() is called with the same parameters, the handle of the host gets reused.  HostDisconnect() will clean this handle, even if his commune.  It's actually documented behaivior.  We have also decided that there may problems like the one you have reached, so it will be removed in a future release.

  So your application will share the handful of host among all discussions, and as soon as we call disconnection, the host handles in other countries also becomes invalid.

  Make a unique HostConnect() and share this handle inside threads is a way to avoid this.  HostConnect() is generally quite expensive, so we recommend in all cases.

• SQL Toolkit crashing with multiple threads

  Hello everyone and happy new year!

  I was hoping someone might be able to shed some light on this problem. I update an older application to use multiple threads. In fact, the thread that is causing a problem now is created by using an asynchronous timer.

  I use CVI 2010, and I think the SQL Toolbox is version 2.2.

  If I execute a SQL statement from the main thread, there is no problem.

  stat = DBInit (DB_INIT_MULTITHREADED);
  
  hdbc = DBConnect( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=sample.mdb;Mode=ReadWrite|Share Deny None" );
  hstmt = DBActivateSQL( hdbc, "SELECT * FROM SAMPLES" );
  
  DBDeactivateSQL(hstmt);
  DBDisconnect(hdbc);
  

  If I add code to perform the same duties in a reminder of the timer, it causes a stack overflow error.

  .. Start the main thread

  stat = DBInit (DB_INIT_MULTITHREADED);
  
  NewAsyncTimer (5.0, -1, 1, &gfn_quicktest, 0);
  

  .. end of main thread

  .. and then the reminder of the timer

  int CVICALLBACK gfn_quicktest (int reserved, int timerId, int event,  void *callbackData, int eventData1, int eventData2)
  {
    {
      int hdbc = DBConnect( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=params\\sample.mdb;Mode=ReadWrite|Share Deny None" );
      int hstmt = DBActivateSQL( hdbc, "SELECT * FROM SAMPLES" );
  
     DBDeactivateSQL(hstmt);
      DBDisconnect(hdbc);
    }
  
    return 0;
  }
  

  The program crashes with a stack overflow error when the DBActivateSQL statement is called.

  I understand that the Access ODBC driver can not support multithreaded, but I only connect to this base starting from the same thread with these 2 statements only so it should be good?

  Any idea would be appreciated,
  Thank you
  Ed.

  I just tried this using the sample provided with CVI access database. It uses a DSN instead of mdb. It has worked out well. I see that no reason multithreading would be a problem here, if you open and close the connection in the same segment of code. I see that you use params in the asynchronous callback connection string. Where did this come from? Maybe try to use the database and see if it works.

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

• AppleScriptObjC and multiple threads

  Hello again people.

  I read some old threads here to have multiple threads in a Cocoa-AppleScript application, but I have not found any that I think that would work for my particular use case.

  Here's my situation: I have a method that expects that the user say a phrase and then runs another method when he hears the phrase. Here is the code that I currently use:

  on listenForQuery()
  set query to ""
          try
              tell application "/System/Library/PrivateFrameworks/SpeechObjects.framework/Versions/A/SpeechRecognitionServer.app"
                  set query to listen for {"Hello"} giving up after 5
              end tell
          end try
          if query as text is equal to "Hello" then my newQuery_(null)
          performSelector_withObject_afterDelay_("listenForQuery", missing value, 2.0) -- do it again every two seconds
      end listenForQuery
  

  AppleScriptObjC is not multi-threaded, but it seems that you forgot that it can use many of the classes and methods of cocoa.  Instead to use AppleScript to control another application, take a look at aid NSSpeechRecognizer in yours - you can give it a list of commands to listen and to define a delegate method that is called when something is recognized.

• Is it possible to synchronize music and photos from iTunes from multiple computers?

  We have two MacBook Pro - one for me and one for my children.

  Currently, I manage all the music and pictures via my Mac (synchronization of iOS devices), so there is a place for all the music and photos.

  However, children now want to be able to manage their own music and photos.

  Is it possible to synchronize music or photos from multiple computers? for example:

  -Sync Mac and pictures of the other music

  -Synchronize Mac music

  Thank you

  The key thing here is not the machines it's libraries. Devices can synchronize an iTunes library at a time. You have to arrange if both computers have the same library (problems with maintaining them synchronized or using at the same time), or seek a centralized service such as game or music from Apple (with her own set of questions).  The key is that the media distributors wish to exercise tight control over how music and movies can be shared (they don't care about your photos).  You can do things with the homepage of sharing with family.

• Writes a text file from a network computer to another computer on the network.

  It is possible to write a text file from a computer on the network to another computer on the network through labview without using FTP?

  Hi bebo_lm,

  It depends on how they are connected. If you have a 'normal' access to the pc and you can write on a hard drive of the other computer, you can use the writing functions of files or the copy of the file. If they are not connected like this, then you need another service. Why you do not use FTP?

• method accewwing from another thread causes some 'bad object type' error with c# VS2008

  I'm snapping a picture to a main Viewer, draw a rectangle around an alignment and extract the part of the image to a different viewer for further processing. I tried everthing and all was good until I started to build a Wizard for the operator through the process of the market and do things automatically. If I have access to this method of the mainform thread, everything works fine. If I access it from the thread of substantive assistants work it fails and gives the error "you have provided the wrong type of object to the function. Spend a CWIMAQRectangle instead. »

  public int ExtractToGP1()

  {

  CWIMAQLearnPatternOptions LearnOptions = new CWIMAQLearnPatternOptions();
  CWIMAQRectangle RoiRectangle = new CWIMAQRectangle();

  int Count, result;

  Extract the region corresponding to the model selected in the main Viewer

  Result = axCWMachineVision1.GetSelectedRectangleFromViewer (axCWIMAQViewer1.GetCWIMAQViewer (), RoiRectangle, true, 1); //<--error>

  Result = axCWIMAQVision1.Extract2 (axCWIMAQViewer1.Image, axCWIMAQViewer5.Image, RoiRectangle, 0, 0);

  I tried to use:

  axCWMachineVision1.Invoke (delegate (MethodInvoker)

  {Result = axCWMachineVision1.GetSelectedRectangleFromViewer (axCWIMAQViewer1.GetCWIMAQViewer (), RoiRectangle, true, 1) ;})} ;

  axCWMachineVision1.Invoke (delegate (MethodInvoker)

  {Result = axCWIMAQVision1.Extract2 (axCWIMAQViewer1.Image, axCWIMAQViewer5.Image, RoiRectangle, 0, 0) ;})} ;

  but this only works if the method is called by the main thread.

  Resolved to myself. Not really a problem of OR.

  I moved

  CWIMAQLearnPatternOptions LearnOptions = new CWIMAQLearnPatternOptions();

  CWIMAQRectangle RoiRectangle = new CWIMAQRectangle();

  for my vision instead of having it in the method class, which is in the mainform class

  Then use Vision.RoiRectangle vs RoiRectangle and Vision.LearnOptions vs LearnOptions.

• MenuItems run() method that is called from the thread eventdispatching?

  Hello

  is it? I know that MenuItem itself extends thread, but I wonder why this method is called run() and finally and above all it would'nt be worse if this method would be called from a Thread.

  THX

  In fact the menu items are run on the thread of the event. You can see this by creating a menu item long-term. The menu will not close and will not refresh the screen.
