• Serializing TCP reference use?

  Do I need to serialize the use of my TCP reference?  I.e. I control access (using semaphores) my TCP reference when you use the reference in several process?  What is change of response during the review only read write?

  I realize I can create a queue and processes to manage all my writings over TCP, but that the method does not work in my situation.

  You have no need to serialize access TCP write, as long as you don't care about the order in which messages are sent. You won't get pieces of two different writings interlaced with each other. However, as Crossrulz said, you will have a problem with TCP read if you need to match messages with messages received.

  If you do not use an architecture of response control, it would be reasonable to put written TCP where necessary, but all TCP reads in a single loop, and every time that an update comes through, send it to all stakeholders of the code by a registrant or a functional global variable. The only problem with this is that is dying of the TCP connection, you must reconnect, then you will need a way to update the TCP refnum everywhere.

• Get VIM object by reference using plugin vCloud

  Hello, any suggestions on how to recover a VIM oppose in reference to a host vCloud?  I am looking for resource support provider TDC pools.  Here's what I'm trying that produces a null result:
  

  for each (var in {VclHostManager.getHostList () vcdInstance)}

  vcdInstance.login ();

  for each (var in {vcdInstance.toAdminObject () .toAdminExtensionObject () .getVMWProviderVdcs () pvdc)}

  for each (var rp in {pvdc.getResourcePools ()})
  

  var rpVimObj = vcdInstance.getEntityByReference (VclFinderType.VIM_RESOURCE_POOL, rp.resourcePoolVimObjectRef);
  

  rpVimObj is null

  }

  }

  }

  
  

  I also tried some variations of types of finder as VclVimObjectTypeEnum.RESOURCE_POOL but also using rp.resourcePoolRef as parameters to getEntityByReference.  The vCloud host/plugin version is 1.5, with vCO 5.1.

  Hello

  There is a way! First, you must get the MoRef of the providerVdc to identify the resourcepool in a VC. But beware, in environments with multiple vCenter servers the MoRef is perhaps not unique (see here and here).

  I think this code will fit your needs:

  //A Moref is a VC-Identifier
  var rpMorefs = new Array();
  
  //do this for all vcdHosts
  for each (var vcdInstance in VclHostManager.getHostList()) {
  
       vcdInstance.login();
       //get all Provider-vDCs from vcdHost
       for each ( var providerVdc in vcdInstance.toAdminObject().getProviderVdcs())
       {
          //Prepare query - getProviderVdc by name
          var expression = new VclExpression(VclQueryProviderVdcResourcePoolRelationField.NAME, providerVdc.name, VclExpressionType.EQUALS);
          var filter = new VclFilter(expression);
          var params = new VclQueryParams();
          params.setFilter(filter);
  
          while (resultSet != null)  {
              // retrieve ProviderVdcResourcePoolRelationRecord record
              var records = resultSet.getRecords(new VclQueryResultProviderVdcResourcePoolRelationRecord());
  
              for each (var record in records) {
                  //get all resourcePoolMorefs
                  rpMorefs.push(record.resourcePoolMoref);
              }
              resultSet = resultSet.getNextPage();
              }
       }
  }
  
  var resourcePools = VcPlugin.getAllResourcePools();
  
  //get the vCenter-resourcePoolObject by Moref
  for each (var moref in rpMorefs){
  
      for each (var resourcePool in resourcePools) {
          if ( moref == resourcePool.id) {
              System.log("Resourcepool of the providerVdc: " + resourcePool.name);
          }
      }
  
  }
  

  Another way to retrieve the MoRef is to extract the XML providerVdc (providerVdc.toXml ()).

  See you soon,.

• Archived discussions reference useful or correct?

• Use an external reference to AOchannel

  Hello

  Using a device of 6259, I try to generate two analog outputs in a task. However, one of the outputs analog must use an external reference (using APFI1 for example).

  The problem is that I can't find a way to indicate the external reference to a single channel.

  Even though the documentation says that the AOChannelCollection was a member of the public "Item", this is not the case.

  According to the manual of the 6259, it must be possible to assign the internal and external references per channel: "you can use one of the OD <0..3>signals as the AO reference for a different signal of AO. However, you need to externally connect this channel to APFI 0 or 1 APFI. ' - Manual usage of the series of the M, 5-2.

  Thank you.

  Hey,.

  I tested it with the following code by using two channels, each with a different external reference:

  myTask.AOChannels [0]. DacReferenceSource =
  AODacReferenceSource.External;
  myTask.AOChannels [0]. DacReferenceExternalSource
  = "/ Dev3/APFI0";
  myTask.AOChannels [0]. DacReferenceValue =
  10.0;
  myTask.AOChannels [1]. DacReferenceSource =
  AODacReferenceSource.External;
  myTask.AOChannels [1]. DacReferenceExternalSource
  = "/ Dev3/APFI1";
  myTask.AOChannels [1]. DacReferenceValue = 5.0;

  Hope this helps,

• Using an array of references to Boolean controls as the input to a sub - VI edit propierties of orders...

  Hello

  I have a group of boxes and I want them to be exclusive one to change the objects visible to my vi when I change their State. So that my clear code, I decided to create a Subvi, which implements these features. My Subvi recives an array of references to objects that I want to change the visibility, an array of references to the boxes (to be change it's values to make them exclusive when one of the boxes change it is State) and an array of the values in the boxes in the last iteration (to be able to detect that we changed to true and false to others).

  The problem I have is that when I use a node property to get the actual values in the boxes in the Subvi (to compare to their State previus and detect changes) I will get a type variant, and not a Boolean value. I tried to set the mechanical action of Boolean references used as input in the Subvi as switch, but it doesn't seem to work. I understand this is cause of the Sub - VI does not know the type of Boolean values that will receive and assume the worst case...

  Is there a way to do what I want?

  I hope I've explained myself... Thanks in advance!

  There are several ways to deal with this, but it would be useful to see your code. Send the cluster in a VI, or those of the individual references boxes? It sounds like you are not using a strict reference. The workaround, since you know the type of data is to use the variant data and change the variant to a Boolean value, but this should not be necessary. Once again, some postal code so that we can be more help.

  Edit: looks like you are trying to hard-code the Radio buttons. You know LabVIEW has Radio buttons now, no?

• A limit to the reentrant instances run using the VI server and asynchronous call?

  I have an application that attempts to launch many incoming preallouees clones using the server of VI with asynchronous call to start. I find that it seems to be an upper limit on the amount of clones that can be run by using this method. 26 Nations seem to run and then in addition more clones are laid but they seem to be just sitting here do not run. I confirmed this behavior by all launch on the performance front panels.

  Is there something I'm missing here?

  You use option 0 x 40 incorrectly.   That allows you to create a pool of clones and aims to created that only once (I ran up to 10000 clones with a reference using 0x40).  If you want a clone by reference, then just use 0x80.

• free step reference acquired by GetStepByName

  Hello

  Get a reference to a step object by calling GetStepByName. Aid said: "release the reference to object when you are finished. However it is not said how to release him. I can't find a function like ReleaseStep in the API. It goes the same for GetSequenceByName. Is there a global function to release these objects?

  I use GetSequenceFile in the same application, and I can release its reference using ReleaseSequenceFile. However, it is not an equivalent function to release references step and sequence, or at least I couldn't find it.

  I am currently working on the customer site and appreciate quick answers.

  See you soon...

  TestStand uses COM objects and the GetStepByName function returns a COM object.

  'release the object reference when finished' should be done using IUnknown::Release to the COM object.

  Object returned by GetSequenceFile file sequence reference is a special case where you call the ReleaseSequenceFile function both IUnknown::Release.

  However, in many languages, there is a smart class that serves as a wrapper for the underlying COM object. Ex: CComPtr.  These smart classes will do the job of the call to release function and you do not have to expliclity call IUnknown::Release.

  Also note that, if you use GetStepByName, GetSequenceFile or GetSequenceByName in the expression of TestStand and store the reference to an instance of an object reference variable, you should not call IUnknown::Release function since TestStand automatically calls IUnknown::Release for you.

• Regression of 8.5 to 8.6 using a waveformgraph without a trace

  I have a regression bug for updating my code of measurement Studio 8.5 in 8.6.1.

  Reproduction:

  1. create a new Windows Forms application

  2. Add a WaveformGraph to the form

  3. Add a slider on the graph

  4. specify the Cursor Position in X = 0 property

  5. get rid of the automatically inserted plot to manually delete the field and all references using the code editor.

  6. launch the project

  8.5, works.

  However, a null reference exception happen with 8.6.1, in the cursor EndInit method.

  As you can see, a graph of waveform without any plots is created. If this is not achievable by working with one designer, it is a requirement in my project and it worked very well for a long time.

  Step 4 the omission also solves the problem.

  I would very much like to see this problem fixed in a future version of Measurement Studio.

  Hi Christian,

  I could reproduce it here.

  I will forward it to the R & D

• Get the reference to open UIS

  Hello

  I want to create a Drop-in sub.vi that can get a reference to a user interface that opens. I can think to do the simplest is to use the current node screw in the memory, then open their references using the name of VI and then check if the front is open. The question I have is this should be voting and it seems like an inefficient to make way. Can anyone think of a better way to treat it?

  Thank you

• Reference to a while loop

  If you open references to a LabVIEW object, such as an application,
  control or VI, close the references using the LV object close
  Datum feature. Otherwise, the reference remains in memory even
  Although the VI is no longer use it.

  This quote is from the development Guide of NOR. I realized that I used for references without closing them. Even if I never met no problems, I decided to add a close reference to my programs. My question is, should I put the reference and close reference as well live in a while loop and open/close each iteration or should I use reference open before a while loop and close after the while loop, in this way, I'll have to use a shift register to maintain the reference. Or if there are other options. Can someone give some advice?

  Thanks in advance,

  Wang Guangde

  Open and close your references outside the loop (i.e. open the ref before the loop and close it once the finished loop execution).  Repeatedly opening and closing the same reference inside a while loop is unnecessary and takes up an unnecessary overload.

  Also, because the reference does not change with each iteration of the loop (unless you're doing something for her specifically?), you don't actually have a registry change.  You can use one if it makes you happy, however.
