Problème de blocage écran block diagram et front panel

Bonjour,
Je ne sais pas pourqoi, après avoir chargé Labview 2013 (après avoir utilisé LabVIEW 2012 SP1), dès que j'ai un block diagram ou front panel sur l'écran, je n'arrive plus à les manipuler après la première action.
Pour y arriver de nouveau, il faut que je réduise toutes les fenêtres LabVIEW puis que je réactive celle qui m'intéresse. Je peut alors faire une seule action puis il faut que je recommence l'opération de réduction-agrandissement.
Où est l'erreur, dans Windows (7), dans LabVIEW, dans une commande qui s'est mal faite ?
Le problème ne se résouds pas si je redémarre mon PC.
Peut-être faut-il que je désinstalle et que je réinstalle tout.
Quelqu'un a-t-il déjà renconté ce problème ?
Merci pour vos réponses.

Bonjour et merci pour votre réponse.
J'essaie de me dépatoiller de ce problème avec l'aide du service support [(Reference#7411882) Phone Support E-Mail].
Malheureusement l'opération de désinstallation et de réparation qui m'a coûté 4h n'a pas abouti car j'ai toujours le même problème.
Pour simplifier cela commence par ça :
c'est l'écran d'accueil de LabVIEW.
Si j'attends quelques instants avant de cliquer sur CLOSE de la fenêtre WELCOME to LabVIEW, je ne peut plus le faire !
Même l'activation de la croix X de fermeture de cette fenêtre ne marche pas !
Pour y arriver, il faut alors que je réduise cet écran puis que je le restaure et seulement alors je peux fermer cette petite fenêtre !
Par ailleurs j'ai ce phénomène :
Je ne sais pas pourquoi, après avoir chargé Labview 2013 [Version 13.0.1f2 (32 bits)] sur Windows7, après avoir utilisé LabVIEW 2012 SP1 sans problème, dès que j'ai un block diagram ou front panel sur l'écran, je n'arrive plus à les manipuler après la première action.
Pour y arriver de nouveau, il faut que je réduise toutes les fenêtres LabVIEW puis que je réactive celle qui m'intéresse. Je peut alors faire une seule action puis il faut que je recommence l'opération de réduction-agrandissement.
J'ai en fait le même problème avec la page d'accueil de LabVIEW qui devient inactive après la première action.
Cela se produit sur le PC fixe.
J'ai une licence site Université qui a été enregistrée.
En espérant que vous aurez une solution...Cordialement,

LabVIEW 2011 Block Diagram/Front Panel reacts slowly

Since today the block diagram as well as the Front Panel of my application (using LabVIEW 11.0) became very slow. Any modification (add item, move item, scroll etc.) takes more than a second. Restarting LabVIEW helps for some time and then it becomes slow again. Restarting the PC did not help either.
So, I tried to remove all items added today but the effect remains the same. When I try to close the Project Explorer LabVIEW does not react anymore (not responding). Very annoying.
I tried also modifying the settings of the graphics card: nope.
What do I do? Start the project again?
Any suggestions except not using LabVIEW for further projects?
Would be appreciated.

Block diagram, front panel messed up

Why do block diagrams and front panel controls get bunched up and screwed up when you open vi's on different computer with different labview versions.
Can anything be done to prevent this?
Does everybody have this issue?
Thanks,
Dustin

You can _try_ to address this issue by right clicking on the vi's icon when it is open in the edit mode, select "VI properties", select "Window Size". Under this selection there are two selections that _may_ help, they are supposed to partially address the issue you are describing. I never had much luck with them in the past, have to admit I have tried them in a while, try to find out what the target system's resolution is and develop the code in that resolution.

LabVIEW exits while editing block diagram unexpectantly

Hi all, while editing block diagram in LabVIEW 2010, I have experience some strange behaviour from the software. I have two monitors, one has the front panel of main VI and the other - block digram of the specifed VI. When I switch from block diagram to front panel, and vice versa, every now and then the LabVIEW exits unexpectantly without the notice. Upon restarting the program again I get the undo.cpp error. I have attached the error log for my clarification on the type error that I am dealing with. Does anyone have any ideas why this is occuring? Thanks in advance for your help.

Thanks for all the responses.
I was using an existing VI as template to create a new program. There were nested loops in the original program and I needed the logic for the outter loops only for the new program. After deleting many objects in the 'yes' case in the inner loop, I was left with many loose wires in the 'no' case. And that's when my problem started, when I was trying to delete them. Yes, I tried rebooting my PC and that did not help. The problem seemed to get progressively worse, as crashing started to happen even when I was only selecting a wire. But somehow I was later able to select one wire, delete it, and did a save. Then I went to the next wire, and so on. My program is now cleaned up and I'm ready to go on. I will experiment more when the problem returns.
Thanks again.

Exporting block diagram image

Hi
I'm in the middle of writing a report that discusses the LabVIEW program I've been working on, I was wondering how I export an image of the block diagram and front panel to include in my report? I hoped it would simply be a case of copy and then paste into clip art or similar but LabVIEW only lets you copy individual objects.
Please help!

I prefer to simply get the FP and BD image using invoke nodes. The attached simple demo (LabVIEW 7.1) will ask for a VI, then create PNG images of the front panel and block diagram of any VI you select. The image of it's diagram below was just created with it.

Aide organisation block diagram

Bonjour,
Je travail sur un programme et mon block diagram est rendu assez gros, pas très 'propre' et pas très navigable. J'aimerais avoir de l'aide ou des trucs pour rendre le block diagramme plus organisé ou plus petit.
Je devrais peut-être ajouter des subvis à certain endroit, par contre j'ai beaucoup de local variabes (c'est peut-être un problème en soit) alors je ne sais pas trop si ce serait compatible.
Aussi plusieurs controles et indicateurs ne servent que pour faire des variables du côté du block diagram. Je sais que je peux les mettre invisibles plus tard mais il y aurait peut-être une autre astuce.
Les commentaires/astuces sur la programmation en général sont aussi bienvenue.
Merci,
Résolu !

Close front panel but leave open block diagram

Is there a way to do this? I would like to have my block diagrams of a few subvi's open but front panels closed so my task bar isn't so cluttered. It's not a big deal, I was just curious

I created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

i created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

Expanding and clarifying what BJD said;
After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up.
The technique of "create sub-VI...copy" always works for me.
There is one more thing that you should watch out for.
The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node.

Block diagram wont open properly

I have written a big labview program for my application. I have been workig on it for 6 months. I keep adding the peice of code every day and save it with a new name every week.
At one point when I added some code into my program, the block diagram started acting weird and wont let me work on the program easily. For If I add an add function, it would take time and insert this function a couple of inches away where I pionted my cursor. Another issue was that; if I add a while loop or for loop or any other structure it would take time and one added it would add a couple of inches away and expand the main program window (Block Diagram) too.
since then, I started using my company's laptop to develop the code. I have no issues with that lap top till today.
But now when I tranfer this program back to my desk top. It wont open the Block Diagram and wont let me edit it. When I try to open the block diagram. the window appear black out and the LabView stops working.
Is this issure ralted to the graphics of my compute or any thing else? Please help me. Thanks
Mansoor

There is a maximum size that a VI can be. What that exact size is I don't know. It does sound like you have one HUGE VI. If that is the case you really need to think more about using subVIs. It will make your program much easier to maintain and extend.
Also, rather than renaming it once a week you should consider using source code contol. Even if you are the only developer it is a much better way to manage your code. SVN is free and very easy to set up. If you do use source code control make sure you separate the compiled code from the source code. This is an option in the VI properties.

How can I open a vi and show the block diagram?

Hi,
I am opening an vi using "Open VI Reference" and "Invoke Methodpen FP", but I want to open the vi and show the block diagram, but I haven´t found any method (Invoke Method) to do that and any property.
Any idea?
Thanks!
Gracinda

OK, I can come up with a reason. I have written a program that will search the entire VI Hierarchy of a program and update all of the descriptions for all VIs with the top level program part #, the name of the top level program that the VI is used in, the company copyright info, the ITAR notice, company address, the name of the engineer performing the update, along with the date and time. This will also place as a background image on all the VIs, a watermark of the company name, legality stuff and the copyright. It works very slick in that if there are thousands of sub-vis, such as what I'm working on now, it goes through all of them, makes sure the data is there as per company policy without having to open every one of them look at them and update or not whichever the case may be. The one portion that is tough is that the program will detect if there is a description written about what funtion the VI performs and if there is not a description, then it pops up a dialog requesting the user to write a description. The problem is that without looking at the block diagram for the VI, it can be nearly impossible to write a description for the functionality of the VI. So is there a way to programmatically open a VI, show its block diagram (this would only be in the case of a missing description) and then upon completion of the updates, close the block diagram? (I already open and close the VI programmatically in order to read the VI DESC and update as needed, but that is in the background and of course you can't see the block diagram).
Thanks,
Dan

Urgent Help! How can i execute in the same block diagram two separate labview codes each one with diferent execution timings?

Dear All.
I have 2 application progrlams in the same block diagram. the intention is to use the 2 programs at different excuting time for different application, and each have stop and start button ofcourse i will have master stop. But when i run the program, it only works one program at time , that is the 1st block which i make it active only , when i tried to make active the second block it will not work, only works when i stoped the1st one. So, this it to request ur hlep how can i solve my problem. here i have attached some of my program.

Usually you set up a task that has all the channels from all the modules configured. When a loop starts it reserves that task and the cDAQ can't be used by other loops unless you start and stop tasks.
You can have one loop acquire all the data and if you want certain channels to go to other loops you can use the producer/consumer design pattern. If you wanted a third loop you would add another queue and the third loop would dequeue that data. See attached.

Error cluster constant appears different in two locations on a block diagram

I am a newbie to LabVIEW. I have taken Core 1 & 2 and Machine Vision and I have not com across this before.
The image on the right is obviously an Error cluster constant used in the block diagram to create an Error cluster and wire it to an error out terminal. As far as I can tell the image on the left is about the same thing, but why does it look different? The different appearance causes raises a concern that there is a difference in behavior that I do not understand. LabVIEW help suggets that both are Error constants. When I create a new error constant, it always ends up appearing like the right image above. I have not been able to create someting looking like the image on the left.
Could someone please confirm what the image on the left is on a blck diagram?
Thanks,
Bill
Solved!
Go to Solution.

The image on the left is an error cluster control. It has a front panel presence and can be set either via the front panel or through a property node or local variable. The image on the right is an error cluster constant. It is a static value.

In block diagram connecting wire getting blur while saving the VI in LabVIEW 2009

Hello,
I am using Labview 2009, And while I am saving a simple VI connecting wires are getting blurry. What could be the problem?? Is it affect my program while running?
Solved!
Go to Solution.

Go into Tools>>Options, select the Block Diagram page and find the section called Constant Folding. If the CF for wires check box is checked, then this is most likely the reason. You can uncheck the check box and it won't affect the way your code runs.
If this isn't the case, you should upload an image of what it looks like.

How can i avoid to see the source code when any user open block diagram third time without password

i have a probelem regarding source code control. my problem is that when user open block diagram of any sub vi in vi. i would like to make a such a vi which source code can not open after seeing the block diagram thrice time and i dont want to make password to see the block diagram so what can i do ?
give me the perfect solution for this type of problem.

First protect you diagram
create a tap on your FP and create a picture of your diagram and put it on the second tap

Is there a way to add shapes to the shape library, and does anyone make a shape library for electronic block diagrams?

Hello!
I'm trying to use Pages or Keynote to make electronic block diagrams. The shapes library looks like it would be perfect for the job, but the shapes are limited. I know I can make a custom shape, but I live with slight brain damage, which means the mouse is NOT my friend. If I try to make custom shapes, they look like a kindergartener's scrawl, so that's not a solution.
All of the online forums I've been to so far say to use Visio (ick!) and if your desired symbol is not there, make it yourself. Well, several symbols are not there, and the first paragraph explains why this is a non-starter.
I would gladly pay some reasonable fee for electronic shapes, such as amplifiers, mixers, oscillators, etc. if someone made them. But from the help file I can't even see a way to add those shapes to the Apple shape library, so I'm not sure, other than copy and paste, how to handle outside shapes. Copy and paste is pretty labor intensive anyway, but if it's my only option, well, so be it.
Any suggestions? Aside from Visio, that is...
Thanks!
Jim

Hi Jim,
When you say the "Apple shape library" do you mean the Shapes button on the toolbar in Pages?
I don't think there is a way to add to the Shapes in Pages. However, you can create a custom template with shapes that you frequently use. Save a document with your shapes then Menu > File > Save as Template...
This will be saved in My Templates folder, and you can open it with Template Chooser. You will still have to Copy and Paste a shape into the document you are working on. No way around that!
I don't use Keynote, so I may be missing something in your question.
Regards,
Ian.
