• How it happened and how to prevent it: type def cluster change causes the element starts up again

  Hi all

  I have a big nested type nested def cluster, several layers.  I have remove the clusters to use the feature "name" to use it.

  Somehow changing the def of big type causes unlustered elements starts up again.

  For example, the element is the element clustered and used, then after I modified the def type, I don't remember how, maybe remove some items, perhaps rename elements, then the element where B is the unlustered element and used.

  It is very scary because it just happened automatically and no broken error reported and this can spoil the entire application.

  It happen to someone else? How to prevent it?

  Many thanks for any help.

  A search on 'Ben', 'cluster' 'type def' to see that I've been bitten in the same way.

  The earch will reveal the various things that have been suggested according to the version of LV

  First rule of ben from cluster

  Avoid like the plague by deleting or renaming items.

  Other stuff:

  If you need to remove an item, change its representation to something that will break all instances for example change digital chain. Then go all the broken VI difficulty by throwing all the refs for the field you want to delte. And then delete.

  in the LV ealier version, better all the screws that use clusters that open when the change is made.

  In the recent version that neither recommended edititng cluster with all the appellants closed with the theory being that LV handles better the opening of VI.

  Given that I am "Of Ben first rule of the cluster" I don't run in the bug often with LV 2009.

• the stress points and Strict Type Def

  I created a Strict Type Def cluster with Boolean flags.

  I am unbundling of the cluster and some outputs unbundled wiring a slot - VI that I created. This subVIs input is connected directly to the entrance of the selector of a function add channels of true/false.

  It works, but I'm trying to understand why there is a stress point at the when the output of the cluster is connected to the Subvi. Is the reason why, because the cluster is a strict Type Def?

  If I have unbundled a cluster output wiring usually no constraint points appear.

  Turn on your help window,

  Using the wire tool,

  Float over the wires and compare what you see in the Help window.

  I suspect type-def def untyped is being stated by the cooecion point.

  rant value = True

  This scenario is one of the reasons why I freak out on the rumor that the stress points involve a copy of the buffer. They do NOT. LV said you only he does something for the representation of data and you want to inform you about it.

  Done ranting,

• Cluster Type def. array of cluster Type def vs. -best practices?

  Hi all, I'm creating a cluster which is used inside tables throughout my code, of course, I'll need to group and ungroup it several times. My question is:

  Which is preferable? Defining the type def as a cluster, and then add it to a table where it is needed? or by defining the type def as an array of this cluster? It seems to me that it would be preferable to define the type as cluster so def when you group or ungroup it you don't need to index the table first, right?

  Thank you

  Agreed.

  I rarely type tables def but almos always type the cluster that I put in them.

• How to place a (strict) reference of a cluster in a control of Type def?

  Example usage: for example queue message handler it is holding cluster of the references to the controls and lights on the front panel.

  

  I have a cluster of façade of type-def'ed, I need to add to this cluster of references.

  In the typedef for the controls on the front panel (above), I place a control refnum then
  Make a right click-> Select the class Vi Server-> generic-> GObject-> control->-> Cluster Cluster.

  However, this does not produce a typedef of strict type I need.

  How I handled this?

  I managed to place controls in the cluster of typedef of common simple types (numbers, strings, etc.) by placing a refnum control in the cluster and (for the reference of control chain)
  Make a right click-> Select the class Vi Server-> generic-> GObject-> control-> String-> String
  Think it works because they do not need to be strictly typed.

  Delete an instance of your cluster type def on the FP, then drag it to the referance.

• Multiple cluster type def not updated

  I combined group A and Group B with beam by name in Group C.  Group C is spent in a state machine in a shift register.   In some States, there are subvis with Group C as input.  All clusters are of type-def,

  When I change from Group A, I would expect Cluster C to update as well, but it became broken.  Why is this?

  
  

• Table of Cluster cluster type - Def

  Hi all

  I know I've asked similar questions as this one before, but I need to ask again, since I'm still not satisfied with what I got.  Here's my problem:

  I am converting an array of 16 elements in a cluster.  Then I fed this cluster in a cluster of type-def.  Basically, I'm trying to update my new values of cluster type-def will write another cluster with the same number of items inside.  All right, but I make it a point to stress.  If you do not already know, I hate the dowry of coercion.  Is there a way to get around this?  Thank you!

  Yik

  Stick with the point. If you change you def code pauses to get your attention. If you use the type cast, it can hidethe broken wire and you give a very strange accident in a sub - VI that gets these data on the wire or in a different VI complete (summer does.) That's why I covered my head in the previous post. It took Aristos queue and his group to figure out that I had thrown type the wrong type of cluster in a VI breaking a dynamic VI when it came time to free a memory buffer).

  Points of coercion of the biggest concern when has with tables since they cast upward in a type number (u8 to U32) cannot be done in place and requires a copy of the buffer. Arrays can have large buffer duplication is bad. In the case of clusters and type def vs non - typ def a dowry is just an FYI.

  PS Plese non-identiques post time for the same message.

  PPS LV train teaching of stress points are bad. If you take a certification test, forget what we say until after you pass, then still remember when you spent.

• Is it possible to open a control of type-def as string programmaticly combobox control, change it and then close by nodes invoke/property?

  This may sound crazy; but I was looking through methods and solution properties do the following:

  1. Open a cluster of type strict-def.
  
  
  2. Add an element in a chain of the Combobox control.
  
  
  3. Register the control.
  
  
  4. Close the type-def.

  LabVIEW provides the tools to do this within its broad range of pallets?

  Second step is easy, as long as the control or parent cluster is not a strict type def.

  G.R.

  It's tedious, but simple using the VI server / scripting.  First of all, make sure that the elements of additional scripts are enabled in the VI server options.  Now open the typedef as you would a VI.  In the scripts, a typedef is like a VI with no block diagram, only a front panel and control.  You can get a reference to the control that you need to change in one of the following two ways:

  1. Open its containers from top to bottom, using the reference container as the entrance to the owner for the opening of the new control.
  
  
  2. Use of the crosses in the script palette VI

  In all cases, after change it, save using recording method tools and you should be good to go.  The most difficult part is to get the reference to the control.  If you are having problems, let us know.

• Modification of the properties-type def drop-down list box

  I have a group of 32 cases of a def type. The def type contains several different types of control. What I have to do is to change the properties of the list box for each of the type defs. Normally, I would create an array of references to change the properties for each of the type defs, but when I try this I can not access the properties of string [] for combo box selections. The only way I found to fix it is to create a reference for each individual drop-down list box item. It is labour, since I'll have 32 elements. Is there a way to beeter to do this? The first screenshot shows the issui I'll have, not being able to change the properties of specific elements within each of the def type at runtime through a control [] array. The second screenshot shows the only solution I've found so far, which is not very practical.

  You will need to set up (for a more specific class) control to a type of combo box for the particular control [] index that has the combobox control if you want to access the drop-down list.

  You can also access the combobox in a cluster based directly, rigth click on the control reference and a link to the element cluster directly.

  The last option is to make the strictt of typdef will fill all instances with the channel list [] given that it is a strict property.

  the approach is based on the weather, you plan on changing the list during execution.

• How to display scrollbars on Type Def

  Dear programmers,

  Question:

  Does anyone know how to display scroll bars in a window of Type Def after that both have been disabled?

  Background:

  I have a several projects where the scroll bars do not appear on some Type definitions. It is possible that they may have been disabled by other programmers in the past. This prevent me to see big bouquets stored inside and I have to physically move the entire cluster which takes a long time. I can't find a way to reactivate them (assuming both have been disabled).

  You can reproduce my problem if you start with a new Type def...

  

  Disable the two scroll bars...

  

  After that the scroll bars disappeared, how do I return? Using the control properties > appearance window will not allow the user to customize the scroll bars, and is no longer a right click menu available because you have to click with the right button on the bar itself scrolling.

  For those who work for the glory, I can provide the !

  It's funny, I couldn't find a simple way to do it either!

  You can try this code snippet. Please backup your control before you run it. Just browse the constant path to the location of your command, then run.

  

• How to add or edit data in a file Type Def CTL?

  I'm learning the mode with the RIO evaluation package more recent fiscal year to "create a real-time Application.  I want to do something simple to change the function to output audio to produce waveforms that I do in addition to the included "ding" sounds "boing", etc..  I believe that (1) the data are contained in the SoundOptions.CTL file, and (2) I can use "export to Clipboard" to display the data in the existing table, and (3) in the Panel before the Type Def CTL, I can add a new element of the Enum.  My question: how to associate my new element an array of data new1D?  Or modify existing data to different waveforms?

• password type def

  Hi all

  I want to do a def type or type strict def (not sure that it would be) a password, so that is the password must be updated, I can just change the password in the type type def/strict def and the change will apply to all programs that use the constant/control of password?  How?  Thank you!

  Yik

  You could just put the constant (string) into a vi that has this, which could then be used everywhere. Change he would spread to all the places it is used. Or you could do a typedef is enum, recovery of control 'strings []' with a property node, for the comparison of your password. I put in form encrypted to a text file, read during the initialization of the program, which allows me to change without having to recompile the program. In many environments it is no such thing as a small change program, no recompilation, reconstruction, requires a rigorous new test/requalification to absolutely confirm that the functionality of the program has not changed. That's why I try to not hardcode the constants universal ones, like pi.

• Can I use several type def enums in 1 VI?

  Is it possible to use several type def enums each has its own States? In the larger scope of things, I want to use it in a MANUAL.

  Thank you

  Of course, you can have several type def enums.  I don't know what you mean by "in 1 VI.  Each typedef enum will have its own .ctl file.

• type def

  Trying to use and understand the strict type def and def/control type.  Thought I heard until I opened the Level.vi of Simulation-Tank delivered w Labview (2014).  On the front panel are two Boolean flags.  They have been modified to look like symbols of value (I guess) "ISA symbology.  If I understand type defs must be a file *.ctrl with the updated the boolean.  I can't find a.  How were these implementation to the management of both Boolean and still put in the Simulation-tank Level.vi.  I read what strict type def and def type are and think I understand.  What is control? and how it is used.  When I change mode in the def type edition and make a right click on the Boolean value, select "photo", it shows four photographs of the Boolean in 2 different States... ON/OFF/ON/OFF.  Why 4?  Why not just in MARKET.

  There are three options for custom controls: control and definition of Type strict definition of Type. Only the last two are related to a master copy. A custom control has no such connection; When it is placed on the front panel, it is independent. That's what you see in this example. If you don't need or want every instance of a control to update when you change the .ctl file, then you must use a control rather than a type definition.

  There are 4 States of image to Boolean values:, off the coast of the transition to and on the transition from Off to (I don't remember the order of the last two). This is useful when you want to display an image for the transition, for example while you hold the button of the mouse over the control.
