• Cannot use the references in Subvi cluster (error 1055, invalid references)

  Hello

  I'm going through a lot of that through a cluster to a Subvi.

  The idea here is to manipulate objects in the MainVI in the nodes property thorugh Subvi, which gains the reference number of the cluster.

  In the Subvi, I use unbunling by name to access the references I need. However, I get an error 1055 (invalid references) every time I try to access the object by using the node property.

  What I am doing wrong?

  Attached you will find three files:

  The mainVI: Main.vi

  The Subvi: Single_Cam_RefBased.vi

  The def of the type for the cluster: RefClusterTypeDefinition.ctl

  Thanks in advance,

  Marcel

  The constant you have wired to the bundle is not the same as the cluster of type defined wired to your Subvi.

  I was going to say the same thing. This should be the first thing to try. (I haven't studied the Subvi, but it seems buggy too...)

  COMMENT: Again something is screwed in the current VI which makes no sense. Hovering above the terminal should tell us information about the corecion, but in this case it is said that the terminal is something like a cluster of error. This might just be a cosmetic bug...

  

• How to access the property of ListBox inside the Cluster element names?

  In LabVIEW 2010, I have a group of controls on the front panel. In this group, I have a ListBox. How can I access the Item property for the ListBox object names in my block diagram.

  Of the bunch, I can get control ListBox, but which returns a value of I32, probably the index of the selected item.

  In the block diagram, how can I get the name property of the item in the ListBox control since a reference to the Cluster?

  Thank you.

  using the table 'orders' in your cluster, you can access each item. Next, you will need to convert the reference to a 'class more specific' with a reference to an arbitrary list box (or a constant reference of the required type), then you can access all the properties of your listbox.

  

• Access and manipulate elements of the cluster

  I have a group of 4 elements. One of the elements is a ring with 4 data entry. Is it possible to manipulate these entires 4 data based on a condition?
  For example, when a condition = 1; then 3 ring entries will be disabled and grayed out. When not, all 4 entries must be enabled.

  Is it possible to get the local variable for those inputs of the ring in a cluster. or ideas?

  

  Hello

  When you right-click the control of the ring, you will have a Create-> property Node-> disabled]

  AS LONG AS you call the command is not strictly Type Def or the cluster that contains the control of the ring is not strictly of Type defined, you can use property "Disabled items []" to get the behavior programmatically.

  When a condition is true, the index numbers of items that need to be disabled for this hardware node of wire.

  Edit: I see that dan_u already answered, but I couldn't open the dan_u vi, I LV 2010.

  then attached the vi according to my explanation.

• move the cluster for sub vi

  Hello

  I want to spend a cluster that can change its content to one under VI. The cluster does not change by program, but during programming, that is, I could add or remove items in the / cluster. Using direct wire or local variables I would have to change each sub VI that uses the cluster updated the. I also tried the typedefs, but I met the same problem.

  At the same time the Subvi should be able to update the cluster I spent.

  In C++, I use classes like struct (equivalent to the cluster of LV) and pass a pointer to a class object to a function. Within the function, I choose the members of the class I want to use inside this function. If I change the class structure, the functions of the Word are not affected (of couse only as long that I remove irrelevant of class members of the called function).

  Example (from C++):

  settings * param;  'settings' is a class that I use to group variables

  doSomethingUseful (param);

  / * the doSomethingUseful function uses the pointer to parameter and accesses the members of

  Param-> variable1

  Param-> variable2

  ...

  Hereby, I can change the values of variables stored in the param object

  Best,

• getting Ref cluster from the cluster control

  I have a control ref which is introduced into a Subvi.  The control itself is part of a cluster that is an external code in VI that I work.  I want to get the property label.text of the pole of the control reference within the cluster to which I have access to.  What is the mechanism or the property of the control ref which allows me to join the cluster that contains?

  The GObject class must have a property owner. I think for the objects inside a container (such as a cluster), it returns the container. The property itself probably returns a GObject reference, so you cast down to the control class to see the label property.

• How does the cluster?

  Hi all

  I am subsequently helps him learn how to use the cluster to reduce the number of inputs/outputs, but it is quite confusing that how do you know which is which. It follows from the order, whether or not we have added to the cluster? I put a cluster contains 4 numbers DBL as an entry of my Subvi. I name the elements of each DBL as A, B, C, D. In the main code, I create a cluster contains 4 DBL and trying to feed on this cluster in the Sub - VI. But how do I know what number I feed in the main code is A, B, C and D?

  For example, I create a Subvi with the participation of a single cluster. The cluster has 4 numbers DBL named A, B, C and D.

  

  Now if want to feed a cluster in this sub - VI, I create a cluster and connect the 4 digits in this cluster. But if I use the bundle cluster, I need to connect the number in order thus to fill A, B, C and D. But if this Subvi was created by someone else, how can indicate the order of the elements in the cluster WAITED?

  First, you must give the elements of the cluster in the control Subvi the same names (A, B, C, D) as used in the VI call and also to ensure that the order of cluster is the same. If you are not sure fight the cluster command, you can reorder the items (right click) and select the desired command. And Yes, the initial cluster order is the order in which you have added the items.

  Generally, it is preferable that the cluster a typedef and used worldwide. This way to the typdef change is propagated to all the places where it is used.

  It is often more auto-documentent and cleaner to use together and ungroup by name. A constant of diagram of typedef wire upward 'bundle by name' to make the labels available.

• Update only one item in the cluster while avoiding race conditions

  I have a cluster called "Inputs" that has a bunch of data within all kinds of data types.

  I have several loops in the code I want each of them to update a specific element within the cluster.

  I have to get the cluster use this Bundle by name on the specific item and then rewrite in the cluster.

  This way I have racing conditions because two loops can 'be' the cluster at the same time, but when they rewrite a wiil overwrites the other.

  How can I avoid these race conditions?

  I am familiar with Globals functional if it is connected to a possible solution (I have the feeling that it is..)

  Thank you!

  I still think that my suggestion to use the value of data references would be easier. The structure of the International preliminary examination will block the concurrent access to the data cluster: no race condition.

  

  The last loop (option) shows how to query the State of the heap of data.

• Access to the new data in Event Message user callback?

  I use the Simple OI LabVIEW as a template for my user interface for TestStand.

  The sequence sends a Message to the user to the IO to the string array of tests to run.

  But I'm having a lot of difficulties this string data in table for the VI event reminder.

  I don't want to use a global variable and so my method without success so far has been as follows:

  1. use a Refnum at the matrix and pass in the event reminders VI through the cluster Config

  

  2. the "selected Tests" in the entry in the Config cluster event reminders VI is a generic control Refnum

  

  3. the selected Tests (below) is then delivered and passed in the User parameter

  

  4 but how to convert the refnum control Tests that are selected in the original array of strings in the real callback?

  ???????

  Also if there is someone who can suggest a better way to do this then please let me know.

  The line at the bottom is - how to get the most recent data in the event callback function when it is called?

  Thank you very much

  Ronnie

  Ultimately to get this working, I gave up on the string table and changed to a ListBox instead. It was easy then to access the properties of the listbox through the refnum. Probably a major flaw in my understanding of how string refnum work tables.

• Can you attribute programmatically size when you use the table in the Cluster service cluster

  I use the table of the Cluster service.  The only way I know to the size of the cluster is to right click on the function and set the Cluster size.  But what happens if the length of my table changes?  Is there a way to make the cluster size is the number of elements in the table?  Seems like labview should do this automatically at run time.  There may be some nodes of property I don't know.

  I tried the SQL statements, but it always boils down to having to know the number of columns is in the database prior to execution.

  What I did to generate the object to be a cluster to match database fields.  My recordset is an array of objects.  Then I a vi member to build a recordset from the database and another Member vi to retrieve an array of clusters of the recordset object.  If the database changes, I have to change the subject and these two vi.  All the other Subvi call these two for the manipulation of data.  No other sub - VI have bundle and ungroup functions in them, only the vi of two members.  Thus a change in the database requires a change of control and two vi.  Not too bad.

  (I'm tooting my Horn in choosing me as accetped solution provider.  I learned this bad habit of others here on the forum.  )

• Node property of a control inside the cluster within a table

  I created a control that has a cluster to a Boolean, a string, and a digital.  Then, in my front, I created a table of these custom controls.  I wish I had access to the property of the controls inside the cluster in the table.  That is to say, I want to change the color of the Boolean or blinking, or "disable and gray" text box.  I think I'm on the right track, or maybe I'm on the wrong track.  I joined and example VI (testtray.vi) and control that I use (UUT_Display.ctl).  Please excuse the use of a flat Structure of the sequence, I know it is bad programming practices, but I just wanted to throw something together.

  Any help would be appreciated.

  Items in a table can have different values, BUT each element of the table share the same properties.

  "Blink" is a property when you make one in tha table blink you will all Flash.

  This restriction does not apply to clusters.

  So in theory, you could develop an XControl that has a data type is an array, but the display is actually a cluster that resembles a table. But write an XControl is not a trivial task.

• TMSXE connection to the Cluster of TMS

  When you run the TMSXE Setup Wizard can't connect to TMS by using its FULL VIP domain name. If I use each tms server name individually this works, but not when you use the cluster name or address VIP (behind F5 NLB)

  I can connect to the site of TMS using the FULL name of the VIP

  Don't know what else to check. Any help would be appreciated.

  Note: All applications run on different Windows servers, even VLAN.

  Thank you

  Hi Frank,.

  Please let me know is does not connect or there is a problem with authentication.

  Have you tried to access the MSDS on the web interface of the server tmsxe, it worked?

  Kind regards

• Locking ESXi 4.1 mode access confirmation no access to the vCenter Server

  Hello

  ESXi 4.1.  I see options in conflict with access to a crowd that had lockdown normal mode activated via a server vCenter VM on a host in the cluster.  The vCenter server that sits on one of the hosts in the cluster lockeddown then became inaccessible or unresponsive connectivity wise.  So no connectivity between vCenter VM or VM vCenter and hosts.  Is someone can confirm if you can connect to this host lockedown by DCUI with root and disable lockdown configuration to allow the vSphere client to then connect to the host with root and troubleshoot the server vCenter VM?

  I read in some messages that this is only possible if the vCenter VM is in place and the communication to the host.  I also read that it is possible no matter what the State of the vCenter server once Total lockdown (disabling DCUI) is not enabled.

  I have this reference of the 'The new lock in ESXi 4.1 Mode' blog http://blogs.vmware.com/vsphere/2010/09/the-new-lockdown-mode-in-esxi-41.html

  "With active locking Mode, the only direct access to the host that remains open is through the DCUI. This allows to perform administrative tasks limited outside vCenter Server, such as restarting the management agents and the display of the log files. In addition, you can also disable Mode of Lockdown since the DCUI. This can be useful if vCenter Server is down or unavailable, and you want to return to a direct management of the host. Normally, without locking Mode, any user to the Administrator role can open a session in the DCUI.  However, in lock Mode, the root password is necessary; no other user can connect.

  Can anyone confirm.

  Any other person who may not be sure these questions, I can confirm that with root credentials, you can connect to the host directly and disable the lock mode regardless of the availability of vCenter.  Only if the Total lock mode turned on, or should I say DCUI is disabled, then you have no choice but to go through vCenter or reinstall and reconfigure the network.  VM would be always available if local or have to be reassembled and re inventoried etc.

• Add the host Cluster in the Cluster data store

  How can I add host/HostCluster in the Cluster data store after the cluster data store is created. I know that we can add at this time, when you create the cluster data store, but how can we add it as soon as it is created?

  I think that as long as the new host has access to all the LUNS that comprise data warehouses in the cluster data store, then no further action is necessary.

  Make sure just that if using CF then zoning is configured correctly and the LUNS are not hidden from the new host.

  Also, make sure you restart the analysis for new data warehouses on your new host so that it can detect data warehouses

• Nodes in the cluster of Flex

  
  Hello

  can someone explain what are leaf nodes in cluster flex? documentation, I see that they are nodes that do not have access to the storage and they communicate with hub nodes.

  Can have the oracle db instances? If yes how data is transferred between the hub and leaf nodes? Through interconnection? It does not overload the interconnection?

  Thank you

  Soumahoro

  The RAC instances are supposed to be present on Hub nodes as they are supposed to be used as DB nodes. This would make the concept of Fusion Cache similar to what we have in previous versions. On the management of the nodes, you must explicitly set, the nodes would be considered to be leaf nodes in the list of the available total nodes.
