• 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.

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

  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.

• 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.

• 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.

• Programmaticaly change type defs

  Hello

  I would like to change by programming a (strict) type def. I tried to open a reference to the .ctl, but that doesn't seem to work for VI.

  In the specific application, I try to ensure that the user can edit the items in a ring that is used throughout the entire show.

  Thanks for your time and good luck for 2013,

  Bert Hannon

  I would like to change by programming a (strict) type def.

  -By definition, you can't do that. This is the compiler that handles the connection between an instance of a control and the CTL TYPEDEF file.

  Do you this in an executable, there is no available compiler and your code will fail.

  a user must be able to modify the elements of a ring which is used throughout the entire program.

  -One solution is to call a Subvi, which accounts for the current list of available items and attach this list to the STRINGS of all the rings] property.  Perform this operation when the window containing the Doi appears, and whenever conditions change the list.

  -Another solution that saves the memory must not store the list in control at all.  I have a project with the channel selector switches of 2800 on a Panel, each with 200 + names channel.  To save memory, I treat it like this:

  ... The control stores only the currently selected value (for example, the STRING [] array has only one entry).

  ... When a MOUSE down? even happens, I change the property to be a complete list of channels, then let the menu to proceed.

  ... In a VALUE CHANGE event, I put the [STRINGS] property to the single selected element (removal of the large list).

  In this case, you don't need to say the ring what values are avaiable, except right when clicked.

  -Another solution is to pass references to the Doi to a Subvi, which attaches the STRINGS [] which are valid at the present time.

• 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.

• Get the reference to the type of control of def

  Hi all

  I've been using VI script to update certain parts of the report and have encountered a problem in a case.  I was not able to get a reference to a def control (.ctl file).  The control is simple enum, and I recorded it as a def type because I use several places in my main VI, although I don't think that my problem has nothing to do with the fact that it is a def type.

  I know how to get a reference to a VI (Open VI reference function), and I know how to get a reference to a control in a VI (function Open VI of the reference of the object), but not a stand-alone control.  Details of the help file for the Open VI reference function imply that I might be able to do this with instructions to "Strictly typed VI reference", but it let me only select files .vi and not the .ctl file.  Please notify.

  Thank you very much

  You can open a typedef of control using the VI reference open and the path of control of wire on the way to the VI.  You can then change the control with scripts by obtaining a reference to the control on the front panel.  If you have a VI with control of typedef, you can get a reference to the typedef (not its instance) by obtaining a reference to the instance and using the Typedef VI or properties Typedef plotted for reference, or the path to the typedef.

  This can be confusing because a typedef is literally a VI without a diagram, and the script processes as such.

• LabVIEW FPGA. Where should I put the custom controls - or type defs in a project

  Hello

  Maybe this is a stupid question - but I'm a little confused on where within a project I should put the controls (or type defs) used in FPGA screws.  If you put in the bit "module FPGA" project, so they come up as "dependencies" - as if they are not in the project within the project when you read/write values in the target FPGA.  Also, it seems that if you copy the project to a different location folder then the FPGA vi can be distributed in a way that she needs to be recompiled - even if you don't change anything - that's not cool if it takes an hour or two to compile.

  I had the controls in the external project for awhile - but seems not ideal from the point of view modular programming, and also, it seems that it may also cause the recompilation unnessary - although perhaps less often that put them in the FPGA subproject.

  Any thoughts?

  I've seen the same behavior and it is a fact that the code must be recompiled if you move a project even if the FPGA code is unchanged. From my point of view, it's a real BUG. This is independent of any file source or target FPGA.

  The other point of your question is not clear relly. Of course, you will get the dependencies if you place the necessary files outside the structure of the target project. But I see no problem to reference them twice because it won't double the source itself. So I suggest to refer to these files several times in the project structure. Actually I'm doing this because I manage a project file LV with different targets CRIO where the complete code for the target FPGA is double referenced under each target.

• problem with the tab control type def

  Hello community,

  There is still much more to learn more about LabVIEW.

  I have a tab control which is a (non-strict) type definition. It has 5 tabs with indicators.

  When I open type def and insert another tab, say three position and close type def, the tab on my fp control will of course win the additional tab.

  But the new number three tab will contain this as the former number tab three content and only the last tab will be empty.

  This isn't what I wanted. I think that I am doing it wrong.

  Is it possible to get an empty tab posted on three without defeat the purpose of a def type (because obviously I could decouple the def of type control, insert the tab and do a new type def).

  Best regards

  Florian

  Florian,

  I hope that you will display the tab as a user interface control in one place. In this case, you can have a typedef enum to subVIs and disconnect the the typedef tab control.

  Thank you

• By the way command def of strict type as refnum slot - VI

  I would like to edit various properties of a control of type strict (cluster) def in a Subvi.  For example, I might want to change the colors or flashing property and have the change takes effect on the next level VI.  My first thought was to move a control refnum to the Subvi.  When I created the front panel for the Subvi, I couldn't find a way to define the type of the command refnum.  When I right click and choose 'Select VI class server' I select generic > GObject > control > RefNum > TypedRefNum.  I don't know how to set the specific type of def so that I don't get a class conflict.

  Is there a better way to do this kind of thing?  If not, then what is the right way to assign the type of a control refnum def?

  Thank you, Mark

  Try a generic control on your front panel and then refnum dragging a copy of your typedef on it. Viola '!

• 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.

• Deleting the definition of Type casuses control a lot of misreferences and program in the block diagram errors

  In LabVIEW 2010, I have a Def Type control i.e. a Cluster with several other controls within the Cluster. Apparently, the references to the controls in the block diagram are based on the order that the controls have been added to the Type definition command. The side effect of this is that if a control is removed from the command of Type definition, many of the done Variable reference in the block diagram or now either broken, or worse still, refer to wrong control in the Type definition. These problems are quite difficult to find and fix.

  Comment: If you create a control of Type definition and make a Cluster. Now add any controls to the Cluster in an order, let's say A, B, C, D. Their types does not matter. Now use the Type definition in one or more controls on the front panel. In the block mark references to controls inside the Type Def would control on FP. Now return to the Type definition and remove the command B of the definition of Type. Now, lots of errors appear. Broken links. But worse still, you see old references to B that now refer to C and old references to C are now referring to the old references to D and D are removed altogether, etc..  This side effect is much more errors, broken links and misreferences than expected otherwise.

  How add and remove controls anywhere in a Cluster in a Type definition, at will, without creating a whole bunch of errors in program, broken links and misreferences for controls in the Type definition that have not changed?

  
  

• 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.

• Enum (type def) - structure of the case called update error

  Hello

  1. One of my (type def) enums is not updated the names of structure cases. I found something that looks like a probable error in the case where the structure,
  2. I had created one of the constants in the enumeration before I did a typedef. Therefore, I made new constants since the typedef and replace the original ones. and still, the structure of the case is not being updated.

  How can I solve this?

  also, I have one state machine inside the other. Is this right way to program?

  

  Somewhere in your code, you have the wrong typedef, or don't replace a control by the typedef. Must not have replaced all. I don't know if there is an easy way to search for; You may need to go through anyway.
