Control ceases to be a typedef
I have create a typedef. I'll place as a constant on my BD. After coding for a while, I'll come back to him to change. When I right click on it it does not give me the option 'open the typedef '. As a solution, I remove then replace it with one in the record and it works fine and I can open it with a typedef. I find it embarrassing. Anyone see this?
OK, so it is with a constant and not a control? The option is not in the menu at all, or is it gray? (If it is grayed out that means the command Editor window is already open, and you can not open another instance of the editor.) How do you create the constant on the block diagram? You right click on the block diagram, by selecting "Select a VI", navigate to the control and release? Or, you have the command Editor window open and you drag / drop. And if you drag / drop, you drag / remove control from the Publisher of (incorrect) Control Panel, or are you drag / drop the icon the top right (correct) window?
What version of LabVIEW are you using?
I can't say I've seen it.

I have a need to extract the labeltext attached to a parent typedef of various front groups. Unfortunately the strict type defs apply strictly for referenced controls labeltext. Is it possible to use a Panel control/cluster reference before addressing the typedef parent programmatically? Or y at - it a way to extract the original/typedef labeltext programmatically for a cluster given façade/control?
I don't know if I understand. If you are typical of a cluster, each element has a fixed label. You cannot change the item labels in different forums.
That being said, I assume you mean the entire cluster (typedef instance) label. This can be changed, OK.
I don't see any purpose to read the label of the typedef itself, however, it is possible. You must create a node of the cluster (instance) property, then select the 'Typedef VI' property. using VI Server, you can make reference to the façade, read controls (which is the actual typedef cluster) and the text of the label.
Please note that the first property that I mention is part of the VI Scripting, so you'll see it only if you activate scripts VI in LV options.
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.
I'm having a problem with my range of scale settting program there on a xy chart. I am the creation by programming the x and y fit to 0 scale (don't not autoscale), then setting the range scale x and y scaling. The x scale works fine, but when you try to set the scale y I get error 1077 - invalid property value. I read on the forums a possible fix to disconnect the control of interval-y the typedef but still no luck.
I use LV2012 SP1. Any help would be appreciated.
Your problem is not autoscale, you have defined your minor increase to 0. Change to something sensible for X & Y axis.
I'm in a block diagram, a queue, the notifier and several instances of cluster of bundle
that all use the same data structure. There is a typedef of cluster for the data structure.
Of course, each of these objects (define the queue, set notifier, bundle)
you want to know how do you define the cluster.
What is considered best practices?
(1) create a dummy instance of the cluster across data structure
definition is necessary (and hide all on the public Service)
(2) create only one instance and son at all places, it is necessary
But there is no stream on this thread: it's only the cluster * definition *.
which is used, so this seems to clutter the comic.
(3) create only one instance of the cluster control and use local variables
everywhere else the definition of cluster is required. It's _value_ is never
assigned or given read-so no problem with race conditions.
(4) another way?
If you were to clean up someone else's code, how do you expect
See this Treaty?
It occurred to me during this writing that here where I
"unbundle...... code bundle" I could wire the original beam to the
the two "unbundle" and "bundle" - but that would be too complicated
and the size of the comics with useless thread?
Thank you and best regards,
I think that this question is about "sharing" the typedef and not how share data (?) If the cluster control is registered as a typedef (or a strict typedef) but NOT SIMPLY as a CONTROL, then when a Diagram-constant of the typedef is created, it will be updated when you update the .ctl typedef! (and there is no FP control to hide ) Of course if the typdef is already available "close" if necessary, you will be able to use instead - save a spacer of diagram.
See you soon.
Here are the steps I did...
(1) on my PC, I have a strict typedef. As a simple example in the strict typedef Boolean control.
This problem has reported OR R & D as a request for Corrective Action (CAR # 323101) for further investigations. Thanks for the comments!
I have a typedef enum that defines that the DUT is for my automated test device. This enumeration is used everywhere in my code to determine which tests to run and how to interpret the results, etc. I also have a (much indicator tab to be precise) typedef tab control that has a page for each of the ESA with various indicators for each test that will be carried out on it must HAVE specific.
I would use the typedef enum to select which page of the tab indicator to display. I am able to do it with brute force just a U32 converter like this:
But would prefer to (because of my anality) eliminate dotting ugly coercian red (and depending on the size of the code, all memory that I can save help too).
I tried many things, and none seems not to work. In this way, using a type cast, does not work.
And not that this using variants (although it works with this little piece of the code example, maybe because my test set-up is an executable?):
With the variant version, my test fixture survey an error 91 indicating data types is not compatible.
Anyone has an idea how to convert between these two without which dot ugly coercian?
Why not write a little VI with Enum entry and exit of the tab? It should be just a case internally structure. You can do the small icon so it does not much more space than the U32 conversion.
I want to know programmatically if a control on the front panel is a typedef and I want to know the path or at least the name of his *.ctl file in the case. LabView knows it is related to the type definition, but I can't find the property where can be verified programmatically.
Thank you very much
I have a typedef on a façade of VI and I would he re-record a new path/name programmatically.
with a VI I open a reference to the VI and use the method "Save.Instrument" save a copy: true and a path of entry.
What I tried was to open a reference to the VI that uses the typedef, got a property node reference is the Panel, then a property of the table control fact reference - but control generally cannot be "recorded under" but a typedef could - there is no way to do it.
Is there a way to do this?
The control class has a property called TypedefVI that returns a reference to the VI of the typedef which you can then save. The only problem is that this method seems to be a method of script, so you will need to install the script first.
Another alternative, if you do not want to use script commands, is to use the property called on the VI. This returns the names of all the typedefs he uses (which you can then use with the open reference VI primitive), but be aware that this gives you a way to associate a specific control with a specific typedef.
This seems strange to me.
I can create a control to a custom shortcut menu that works without problem when placed directly on the PC, but when I try to do the same for the same type of control when it is in a type definition (three layers of def type deep - but it's a long story), I only get the default shortcuts menu. Even when I disable the menu option, I still get the default shortcuts menu.
This means that a control in a typedef can use the context menu by default in its default state?
Thanks for any idea.
Hey Broken Arrow.
I'm now getting back to this.
I know I'm going down to the lowest level of typedefs to the control itself, but your comment has me thinking... and, Yes, confirmed.
It is a piece inherited from SW so I thought of something that took me in the past. Rather than the next review typedef lower level being placed in the next typedef of higher level, a copy of a panel of control must have been copied so the legacy was get all messed up. I completely Redid the typedefs all the way through, which of course caused some problems, but they were repaired and it is all great work! (at the moment )
SO, the answer to the question is Yes, a custom menu CAN be added to a control, even when buried deep inside the nested typedefs.
I tried to search but could not find this topic. But I doubt if it has not already, examined in the forum of LabVIEW.
In my application, I used custom controls. The application has several "pieces" and each of them uses "similar" (but not necessary even) TypeDef controls that I customized to sequel of the game.
Good feature of LabVIEW is that even if the control file is moved to a different path, he finds and charge it, with a warning. However, in my case, I need to disable this feature for some control files. Is this possible?
I use files from control with the same name, but they are planned for different screws 'call' If this is not a good practice, I can change the names of each control file, adding a prefix/suffix to the name of the calling application. Each control file becomes unique.
But still, this will remain a question. Due to small and appropriate names, I often prefer them with a 'typical' name I would give for such control. As in every application, we have a program of 'hand '. And what I faced, the problem is when I loaded a VI, he 'used' automatically control (bearing the same name as one who waits for this VI) which is already loaded (in a way) by an already open another VI, even if the intended control exist in the expected location. He showed a warning, but did not ask "do you want to load the original, or use the one in the memory?
My question is, is it possible to have a "projected" pathname to be fixed and does not have the VI load the 'recently' opened 'namesake' control under his control expected?
The feature is good, but in some cases, can shut down us or not?
Thanks for the comment Mark!
Yes, it's true.
But what about stop unwanted connections of messsing upward in the first place the program? I mean, before you build a project.
Moreover, if we open a program via the Project Explorer, it would still not allow to open a file whose twin brother is already in the memory. But will it scream before assuming a new connection on its own?
No, the projects work like libraries. Once you have the screw in a project of his name is modified internally, or least how to locate the disk which allows you to open both projects at the same time. The trick here is to get the job done through projects rather than opening the screw directly. As long as you work through the projects themselves, you can use two screws or different typedefs bearing the same name located in different directories at the same time. It's as long as each of them is a member of another project.
I opened my computer today and now whenever I open the mission control, it does not animate the passage, he jumps right between the two States. It's never done this before and I can't think of anything that I could have done to cause this. There is no problems with the feature, but it's just super annoying. Someone knows how to fix this?
the default settings for Mission Control Panel must be as stated

The button Mute, CD / DVD button, Play/Pause button, stop button, back button and next button ceased to control the windows media player and continue to be light after stopping down my PC. Turning off lighting to help the HWSetup/Toshiba Toshiba do not turn off the button illumination.
How can I fix it?
I don't know if this will help, but try to reinstall only the value-added package.
I have a tab control that has ceased to operate at run time. It acts like it is off when turned on. At the time of editing, I am able to click on the tabs and they change visually. When I run it, by clicking on the tabs does not change tabs. I reduced the vi to a simple loop with a delay of 200ms and the tab, with nothing else. The controls on the tab is the only thing in vi. I made sure that the tab is enabled in the Properties dialog box. I noticed a strange thing: the Navigation tab button (in properties), it is all grayed out. Once again, the control tab in in fact active, but it behaves as if it was not. I tried to recompile. Is there another setting? Why key naviation is grayed out? I'm using LabVIEW 2015. Thank you!
Ooops! Problem solved. I did somehow accidentally changed to a flag! Sorry for the premature post.
Control of resource if RIO is a typedef. I want to use a control with a style like the XP style or system. I find for the resource of visa but not for YEW - RIO.
Where can I find or how can I make another control for my IF - RIO resource.
I didn't, so I did!
