• Error during transfer of an array of Clusters for LabView

  Hello

  I'm new in LabView and I hope that this mistake has an easy solution.

  I built a VI to check the validity of a label.  The Vi receives an array of clusters.  The cluster has 3 strings.

  I built a Variable with an exact same structure in TestStand.

  I get the following error:

  Error, parameter 'Sn Range Array': array elements "FileGlobals.SN_Ranges" do not correspond to the LabVIEW or cluster cluster is disabled in the definition of the array element type. [Error code:-17313, could not accept the parameter passed.]

  
  Is attached a sequence with a single step.  and vi.  (the location of the vi must be re assigned to TestStand).

  Can anyone help solve this error?

  Thank you

• Mouseover image control does not appear when it is contained in an array of clusters.

  I've been using Boolean system (with some customization) to impement mouseover animations.  For example (default values Boolean system):

  

  Mouseover feedback works well with my UI, and most of the time everything is going great.

  However, the mouseover image does not load if the Boolean value is contained in an array of clusters (a single cluster with inside Boolean or an array of Boolean works as expected):

  

  The animation of the passage of the mouse works for a single array element in the case above (the one that was clicked more recently), but this behavior is not desirable and it seems buggy if I had to leave this on my UI such what.

  So I guess I am wondering if anyone has encountered this or has no suggested work around?  The few that I thought to date (maintain a separate table for any set of Boolean control systems, verify the details myself on the mouse move event and try to update the appropriate element of the array, avoid using animations mouseover devoted entirely to this set of commands) are not all that desirable.  Although this issue could be considered in cosmetics, the user interface is very important for me because this code is that something shipped to customers.

  It's LV 2011 either incidentally, so if by chance the behavior in 2012 is just let me know (this could only) is a sufficient to convert the project to the top.  If there is a DRIVE ID for this behavior and an employee OR want to share I would also appreciate that.

  Best regards

  Hi John,.

  Thanks for the obvious example of this behavior. I was able to reproduce this problem in LabVIEW 2010 SP1 2011 and 2012. I couldn't find a CAR that has mentioned this unexpected behavior, so I went ahead and filed one myself. For your reference, the number of CAR is 36785, and I think I've included everything you mentioned.

• Change the properties of a cluster element inside an array of clusters

  Hi all

  I have a table of cluster that has the shape of a line with different elements of the screen.

  A list or a tree would not have made it, so I had to use a cluster and make a.

  The problem is I want to change not only the text but also the color of the text.

  Individually.

  I found this:

  http://www.NI.com/example/30904/en/

  But it changes the property in all groups in the table, not just the one I need.

  Some people have the same problem:

  Obviously, even if in a table/list or a tree, you can change the property of an individual

  cells (font, color), you can't do it in a cluster network, by a kind of magic.

  the property of an element of the cluster (font, color) are all connected together, so made

  the use of a table without value.

  A possible hack is available using masking of control, a visible setting and the

  other invisble, exchanging their position, whatever. This is a hack you have to perform,

  Therefore, add another code to maintain.

  Is that still the case, or is it now a more formal way to manage the individual cluster

  Properties, not only its data? After all it is a common example of a real life which should

  managed by Labview. In my opinion.

  Altenbach says:

  One of the elements could be an indicator of 2D about the same size image. You can create text in any color using the features of the image.

  Here's what I had in mind. Seems to work very well (I would refine the border picture fonts, etc., but this should help you get started).

  

• Reference to the array of Clusters with an array element

  Hello

  I have an array of clusters of CONTROL (qualifying as "upper-tier cluster table") with one of the items is an array of cluster cluster (see attached).

  I intend to "reference" of this cluster of high level at different screws (as add item VI, insert item VI, delete the item VI etc.) and access (add/edit delete) the elements of this array.

  

  In my code, how I cataloged the array element (cluster) on the cluster internal (as shown on the figure)?

  I use LV RT on PXI.

  

  Hello smercurio_fc,

  Thank you for your example! Just a question: actually, with shift registers, is an example of creating a local copy of the full range? Even if the value of the lowest level cluster is changed, is the complete table is updated at the end (registry value to offset the full picture at the right end is updated using the reference node and property)? This VI will be slow when the size of the array becomes great?

  Comment of nicely.

• How to change the items in a drop-down list box that is part of an array of clusters

  Hello

  In the attached vi, I have an array of clusters and each cluster contains two drop-down list boxes. How can I edit the items in the drop-down list box 1 for all elements in the array? (All elements of list box 1 has the same elements.)

  By way of illustration, I have also included the case of trivila, for example, edit the items in a separate drop-down list box that is is not part of an array of clusters (combo box 3). Please notify. Thank you.

  Peter

  Right click on the drop-down list box and select Create-> Node-> String() property. Place it on the block diagram. Change to write (right click) and then feed him an array of strings.

• Best way to transfer strings, arrays and clusters

  Hi, I just want to know the best way to transfer strings, arrays and clusters between a PC and a computer-RT (compactRIO) if I want to use them in deterministic loops:

  For a string should I use a published network shared variable flow or network?

  For an array of doubles should I flatten the array in a string and the string of transfer? or should I send it as a picture?

  The same for clusters, should I flatten the cluster or the transfer as a cluster?

  Thank you!

  Transfers on the network are not deterministic.  You ask how to use the data in a deterministic way, once it arrives on the RT system.  Usually, you would create a separate loop, not critics of time to deal with network communications.  The data arrives it is copied in real-time-safe structures such as RT-FIFO to put at the disposal of the evanescent loop.

  I can't give you specific advice on network variables and network flows; Finally, I did this kind of transfer over TCP, until these other options were available.

• Drag and drop the element of the array of Clusters

  I have a project that includes an array of 'tests', each of which is a cluster that contains an array of 'numbers', a matching the regular expression string and an array of "tasks" (all of them, is in turn, a group of elements).

  It is:

  • Tests (table of):
  • • Cluster:
    • • Reference numbers (an array of strings)
      • Regex (string)
      • Tasks (table of):
      • • Cluster:
        • • Task type
          • Basic channel,
          • Measuring channel
          • Other channels

  I wish I could drag and drop to rearrange the task table in an individual event.  (It is a nice-to-have rather than a urgent request - more for my own learning that no matter what).  For now, I've implemented "Move up" and "Move down" buttons

  Examples are fine for a single cluster that includes a table or an array of objects.  As soon as we have an array of clusters, it is difficult to access individual items within a specific cluster.

  Who that it be completed can drag and drop into such a facility?

  Curiously,.

  Geoff

  Hello GeoffF,

  It's certainly doable and you can even use the standard start drag and drop methods/events, the trickiest part is to determine the table of the elements that are selected on the mouse towards the top/mouse downwards and the swap of manual handling.  Fortunately, there are a few decent examples of how do this out there already, I suggest you take a look at this one:

  Example of community: determine the Index of the clicked element Array in LabVIEW

  https://decibel.NI.com/content/docs/doc-22434

  That should give you the selected table indexes, and then all you have to do is to move the elements around around the drop event.  I have attached a very basic demonstrative example that uses this code I just linked (you need to download that as well) and the events referred to swap two elements of the array.   The attached code is just thrown together, you'll want to design something more robust and scalable to any sort of actual use.

  Kind regards

• How to change the tab order of an array of clusters?

  How to change the tab order of an array of clusters?  I have the cluster arranged into a table in the front panel.   The element of the cluster passes horizontal and array element passes vertically.   When I press the tab key, the cursor will move to the item next to the table instead of the next item in the cluster (down to the place overall).

  so you have an array of clusters or cluster and the separate table?

• Programmatically update nested arrays of Clusters? (What is the best way?)

  I have an array of configuration files that is loaded at startup. Then, I need to update the values in this table of configuration values. The attached VI works, but I was wondering if this is the best way. It seems not scalable I added elements that I do need to update (mostly because the real configuration file has a lot more items).

  What is the best way to update an element of tables nested clusters?

  In this version shortened:

  When I click on "Set a new value" it should set the updated for the selected Config values #, # test, a subtest #.

• How can I reference the properties of a control in a cluster in an array of clusters?

  Hello

  I am a newbie of Labview, so any advice is welcome on any code posted here.

  I have one "tick" test VI where the operator is required to boxes that are then "signed". Once all the boxes are signed correctly, the operator indicates that they are finished to enter data and VI requires that a "representative" ticks boxes same as the operator, even once be "signed." I created a "list item" control that contains a set of a string for the description of the check list, a Boolean control object and string for the operator 'tick' and 'signature' and a Boolean control and chain for the Authoriser "tick" and signature. This control is then initialized in a table to create however many controls are required (currently 10), make a table of the clusters. See the jpg for the front panel to clarify this point.

  In the cluster of list control item I want to have the 'case' Authoriser and 'signature' stay disabled and grayed out until such time as the Authoriser is validated (currently scan barcodes), how I want to activate these boxes for the entry clearance officer. I can not reference the two controls in the cluster of element control list in order to be able to change their property to disabled. I'm not implicitly reference the control. I seem to be able to access the array (i.e. a list item control) in reference, but not the controls element in this cluster of list item, this code is shown in "cluster in an array.jpg Reference.

  I turn round in circles for some time now, so any help would be appreciated.

  Ray

  There are two ways to get a reference to an element in a cluster, in a table. The first way to begin with a reference to the whole table and deconstruct it. It's a pain. The easiest is to right-click on the item in the cluster, and then in the submenu to create reference. LV will switch to the block diagram, and you will notice that the cursor will hold a reference to the thing you clicked on. The third way to follow ("... no one expects the Spanish Inquisition... ") is in the create submenu, select the property node, then select the property you want.

• How can I get a ref to a ring in a cluster that lie in an array of clusters?

  I have a cluster (typdef to) with controls. Two controls is rings. I place the latter in a table. I then fill in the chart of the clusters with data. Can I get the ref to the rings in each cluster? I have to load individually, with strings [].

  Ok. Thank you all. This means that I have to give up the structure with a table. I have to have individual clusters, leave say clusters of 4-5, which shows post n to n + 4. Then only I can have the separate charge of rings.

  I did the programming much more, according to me, heavy, but I get it like I want to.

  Thanks again.

• How to initialize rings in an array of Clusters?

  I have a control that has a picture of a cluster consisting of a ring, a string and a Boolean control.     Each index in the array has an associated ring, I want to initialize at startup.

  For example, index 0 lists options for the #1 variable, index 1 lists the options associated with the second variable... and so on.    A code base that is constantly crashing for the second type mismatch "to more specific class" is attached.    This basic structure is inspired by other posted solutions.

  Any ideas?

  You have a loop that tries to mount each control of the cluster of a ring. Try to get a control over the chain to a ring will generate an error, which is what you see. You should only be casting the first element of the array (assuming that the first item is the ring).

  That said, what you are trying to do will not work. You cannot set different strings for the ring for items in a different table. Elements of an array can vary in value. They cannot vary based on properties, and the list of channels would be a property. Therefore, all the rings would have the same list of choices. You can set them to be different.

  I don't know what's your ultimate goal in terms of interface user, but you will need to think of a different way to do it. Is this table of limited length? If so, then maybe you can use a cluster group. Or maybe you can use a separate control to select the game to watch and update you a chain and a ring unique front panel of your underlying data.

• How to upgrade the enum labels when enum is inside an array of clusters?

  Hello gurus of LabVIEW,.

  I'm stuck with one aspect of the design and I was wondering if you could share some ideas on how to move beyond this: I want to fill an array of strings, and then complete an enum inside a table with string values.

  For the purposes of discussion, I'll break you in two actions steps, where it takes place before the second (sequential, not in parallel)

  Action - the user will first ask you to fill a table with 'strings '. The table might look like,

  row0 - "string0".

  Row1 - 'string1 '.

  row2 - "word2".

  and so on...

  Action 2 - whenever the user "action selects two" I would like to fill out an ENUM inside a cluster with the values of 'Action '. In other words, I am trying to dynamically write enum values.

  The cluster has several objects such as Boolean controls, String, control, AND YEAR ENUM (see attachment .png)

  I tried using the ring and enumerations at this stage and have failed him. I read somewhere that the enum/ring is in a cluster and the cluster within a table, what I'm trying to do is simply not possible. If this is the case, can you please throw my ideas, my ideas? :-)

  In advance, thank you very much.

  See you soon,.

  First of all, the question is your cluster is a strict type def and preventing you from updating the ropes of the ring then I turned into a normal type def.  I've also got rid of the sequence and the while loop they were not useful anyway.  Just unzip and run the VI then enter values in the table, as you enter data, that the ring is updated with the new value.

• Using variants to adjust an array of clusters by program

  I try to use variants to build a polymorphous VI to replace four (at time of writing) separate subVIs that are essentially identical, except for the base type of the array.  Each takes in an array of 1 d of the bunches and it resizes with the following code:

  

  Looking through my reference book, I found the non-listed (in the palette) VariantDataType directory (* \vi.lib\Utility\VariantDataType) and have tried to use a combination of them to do the following:

  1. take an array of variant-isee cluster in.

  2 convert the variant by program in table cluster, based on the information coded in the Variant.

  3 perform the operation of resizing table as shown above.

  4 convert the output into a Variant array and the power indicator.

  Attached are the two VI and a group of example commands I use.  I'm running out of ideas; any tips?

  With the help of LabVIEW 2009.

  In fact, I found an even better method.  You go to file > new, make a polymorphic VI and load instances of the various similar screws into the Poly VI.

  Here is the final result.
