Como puedo desplegar un front panel en un cliente mediante un programa cliente/servidor

Quiero desplegar un panel frontal en mi cliente para desde ahi poder ver otros archivos

Hola,
Con LabVIEW 6.1 puedes usar la funcionalidad de los paneles remotos.
Basicamente, haces una aplicacion que maneje los archivos como tu deseas, de manera local, usando los VIs de entrada y salida the archivos. Este VI se ejecuta en el servidor (donde se manejan los archivos).
Usando los paneles remotos en LabVIEW, otros usuarios se pueden conectar al programa en el servidor.

Espero que te sea util esta informacion.

Como puedo ocultar carpetas o bloquear y desbloquiar desde un programa de labview.

Le agradeceria mucho, a cualquier persona que me pueda ayudar a desbloquiar y bloquear carpetas de Windows, usando un programa de Labview. Gracias por su tiempo y estamos en contacto

Hola Anz.
Gracias por utilizar el foro. No estoy seguro de lo que necesitas y me gustaria que explicaras un poco mejor.
Quieres un VI que sea capaz de permitir solo la lectura de un archivo o carpeta, que sea visible o no?
Para lograr este tipo de cambio a los atributos de los archivos puedes utilizar el llamado a una libreria de windows que se encarga de esas propiedades y modificarlas a tu gusto (kernell32.dll)
Te anexo un VI que hace precisamente eso, revisalo y tal vez checando la documentacion de la libreria encuentres la propiedad que quieres modificar(en caso de no ser ninguna de las anteriores) y es cuestion de cambiar ese parametro en el codigo.
Por otro lado, tambien existe la funcion "Set permissions" para archivos donde se ajustan parametros de accesibilidad para los usuarios.
Esa funcion esta en functions-file I/O-advance f-set permissions
puedes ver su utilizacion con el help de labview.
Espero que esto ayude a resolver tu problema y que puedas correr pronto tu aplicacion.

Have a program in which a sub vi front panel pops up when the main vi is loaded

I have a strange problem.
This problem only occures after building an application using LV 8.6 Professional version Application Builder, and I have installed it onto the target computer. It doesn't happen when running the development system.
When I load the program on the target computer, one of the subvi's front panels used in the application appears on top of the main vi's front panel.
This subvi should never appear on the front panel at any time during the program exicution.
It happens to be the Write to Spreadsheet.vi that is part of the standard vi library.
I have checked all calls to this subvi to verify that it has not be modified to make it load or appear when the main vi is loaded.
It is called at 4 different times during the program exicution but in no instance is it set to show the front panel.
Has anyone seen this and if so what was the fix?
Solved!
Go to Solution.

Does the exe file run on your development computer without the popup?
Can you post a VI that demonstrates this behavior?
You've probably already checked, but there are two places that need setting, the SubVI Node Setup, and the File Proeprties Execution tab. See attached jpegs.

Display and interact with a vi front panel on remote C++ app

Hello:
I am new to LV and need a little advice. I need to display a LabVIEW VI front panel in my C++ .Net application that users can interact with to view real-time spectrum data. The C++ app (client) must reside on a separate computer(s) from the VI so that the client can connect from anywhere around the world and interact with the VI.
I am not sure about the basic architecture that should accompany a good solution. We want to use TCP/IP but not DataSocket. I do not have access to Measurement Studio but I do have access to LabVIEW Professional Development System v 8.2. Can anyone provide suggestions on what I need to do in order to
1. Connect to my TCP server using my C++ client app - I have already written TCP client and server code which communicate but now I need to integrate LV
2. Get access to the VI sitting on that server
3. Send the VI front panel to the client for display
4. Allow the user to modify parameters on the front panel displayed on the C++ client, send those changes back to the server, and refresh the front panel displayed in the C++ client given the new parameters (I would like a real-time display of the spectrum to always be available)
Is this possible? Has anyone done this using C++ .NET in VS2005? Are there examples I can mimic or references that will help direct me? I have searched and searched through NI's help and found a lot of good stuff but I'm still feeling confused about the best way to utilize LV.
Thank you in advance!

One more question ... what if I could use Measurement Studio? The documentation seems to indicate that it's easy to create network applications and therefore it would be easy for me to re-create our VI's front panel using Measurement Studio components in my C++ app and then simply connect those components to the networked hardware (TCP/IP or DataSocket) that could be located anywhere in the world.
Depending on what components you are using in your LabVIEW panel, it is probably pretty easy to build a Measurment Studio application to look like a LV panel.
Given that, you could use network shared variables to move data across the network, no TCP programming necessary -- I think that this is pretty easy to do, but I don't know the specifics about variable programming in that environment. Also, you will probably need to add some smarts to the server side to make sure that it is reading to and writing from variables in an appropriate manner.
Question: why can't you just use LabVIEW for the client application also?

Is there a way to disable all vi front panels in Teststand?

I don't want any vi front panels to appear while my Testand program is running. My application uses a lot of vi's and I'm trying to avoid having to reset the front panel properties for each one. Is there a single option somewhere in Teststand to do this?
Thanks.

Hi kevmi2ca,
One could uncheck the Show VI Front Panel When Called box in TestStand for each VI call, if it were checked. There is no other control in TestStand to modify the Front Panel behavior of all VI calls.
This would be a great product suggestion to make at http://sine.ni.com/apps/utf8/nicc.call_me.

How to get rid of the reference lines on the front panel

I forgot how I created a couple of horizontal and vertical reference lines on the front panel. It looks like the origin lines on the front panel. When I move my program to another monitor with different resolution, all the layout is messed up because of the reference lines can not change with the resolution. Did anybody meet this before? How to get rid of them?
Attached are the 2 creen shot of front panels.
Thanks in advanced.

You will have to click on the top menu and choose options see below
when you do this window will pop up and you scroll down until you get to the front panel options. See below

Is it possible to use a Case Structure to hide numeric indicators on the Front panel when they are not in use?

I am rather new to LabVIEW, have only been using it for about 1.5 weeks as of this post, which means I may be missing something rather obvious due to ignorance, but is there any way to have my front panel change as my case changes due to user selection of a certain case via the front panel?
The goal of the program is to make a simple layout for a user that is using the digital multimeter that the proposed code is designed for and I don't want tons of numeric controllers and such clogging up the screen space that don't work with the function the user is using to measure with.
Thanks in advanced.
Solved!
Go to Solution.

Check out the property node for the controls
Visible Property
Short Name: Visible
Requires: Base Package
Class: Control Properties
Displays the front panel control.
This property is similar to the Show Control and Hide Control options on the shortcut menu of a control.
Also look at the TAB control to control which controls are available to your user.

Show Front Panel form VGA output of CVS

I have built a stand-alone Real-Time Application on my CVS by following the method in ‘RT_Getting_Started.pdf’ file, and I think it is successful (because the ‘startup.rtexe’ file is already created in the startup folder in CVS). I was set the application file as a startup.
Is it possible to show a Front Panel of Real-Time Application (Startup program) from a VGA output of CVS without using any PC? I want to use only CVS and Monitor (from VGA output).

hello MFarid,
Thank you for your post.
It is only possible to show some images and counters on the VGA output of an CVS. You will need a graphical operating system (like windows) to present the complete front panel of your VI. There are complete panel PC's (like PPC 2015 and PPC 2115) which are complete PC's with a touch screen.
If you want to make a simple user interface (only some buttons to control the CSV and some simple data presenting) a touch panel (Windows CE device) can be used. Please be aware that you need a Labview touch panel module to deploy to this kind of device. The simple user interface can communicate throug shared variables with your Labview application on the CVI.
So I'm sorry to say that with only a monitor and a CVS it isn't possible.
Many greetings,
Martijn

Example program forces front panel screen size

I am somewhat of a novice at LabView programming. I used an example program as the starting point. I expanded the front panel, added buttons and displays, and added code to do additional things. But when the program gets to the example code, it forces the front panel screen down to its original (example) size. The help messages talk about going to File > VI properties > screen size but none of the settings solve the problem. The code that I wrote starts with a full screen front panel and runs fine until the program gets to the example code then the front panel shrinks. There must be something in that portion of the code that is setting the properties. Anyone know what is happening?

Hi Gary,
Anyone know what is happening?
You already answered that on your own:
There must be something in that portion of the code that is setting the properties.
All you have to do is find that part of code!
Start searching using breakpoints and step-by-step execution (aka basic debugging techniques)…

Hola a todos tal vez alguien me puede ayudar hay archivos en PDF en que la opcion de busqueda resulta pero hay otros que no, como puedo verificar si en esos archivos la busqueda me resulta, ya que sale un mensaje que dice que no existen coincidencias.

También a mi me cuesta entender realmente la pregunta,
La primera respuesta evidente es que se busque una palabra o texto que no esté presente en el texto del PDF.
La segunda razón de que aparezca este mensaje de "no coincidencias" es lo que apunta Mario, que el texto este "trazado" o convertido a contornos antes de crear el PDF.
En Acrobat (al menos en las versiones Professional 8 y 9) puedes ver si un PDF tiene todo o parte del texto trazado:
    En el borde izquierdo aparecen una serie de iconos (Páginas, Marcadores...)
    1. Pulsa sobre el boton derecho del ratón aqui para que aparezcan una serie de iconos y paneles de la aplicación.
    2. Uno de ellos es el de Tags, etiquetas y otro es el de Contenido.
    3. Seleccionalos y en lugar de dejarlos como paneles flotando, arrastra su pestaña al borde izquierdo de la aplicación.
    4. Abre un PDF y pulsa p.ej. en el icono de Contenido (El de Tags produce un resultado equivalente, más complejo)
    5. Despliega los resultados pulsando en el cuadro con un + que aparece a la izquierda de cada Página.
Si se detalla que se trata de: Contenedor > Figura Trazo, no hay texto y no puede efectuarse búsquedas.
Si indica que se trata de: Contenedor > Extensión (Span)> aqui aparece un texto
Entonces al desplegar esa linea de Contenedor aparece un subnivel que pone Texto, también desplegable, al hacerlo aparece como más ramas de un arbol cada una de las palabras.
En resumen que al abrir un PDF y el panel de Contenido, al desplegar la información en este se detalla si hay bloques de texto o no.

Again
For months not believe me look at iCloud in the "find my iphone" and has appeared to me that I sold the Mac but offline.
I selected "remove the device". I hope that no longer appears.
I've been looking and say to disable the "find my iPhone / Mac"
http://www.actualidadipad.com/como-desactivar-el-bloqueo-de-activacion-de-buscar -mi-iphone
http://www.esferaiphone.com/iphone/que-hay-que-tener-en-cuenta-a-la-hora-de-comp rarvender-un-iphoneipad-de-segunda-mano
Once deactivated the next step is very important: disable option in iCloud Find My iPhone: Settings / iCloud / Find My iPhone. If you do not do this the buyer can not use the device when you receive it and to be an iOS device "stolen".
Note: If you did not know step 3 and the new owner already has the device, you can turn off iCloud.com from accessing your data with iCloud and entering the "Search". It is important that the device in question is on and connected to a Wi-Fi network. From there you desplegaréis the list of "My Devices" from the top and seleccionaréis the device to remove. Only lacking click on "Delete my account" should already be all erased or "Delete iPhone / iPad" if ye what not. When ready just have to desvncular device account. Now the new owner and may re-activate your iPhone from iTunes.
I will contact with the owner, who sold it a while longer and do not understand it comes out and you delete: https://supportprofile.apple.com/
Or do not use it ... or not known to have activated the "search" with my account.

Ajustar front panel a tcp 2206

Buenas tardes;
En su momento desarrollé un vi para que se ejecutase en un PC con una pantalla, pero se va a cambiar por una pantalla táctil tcp 2206. A la hora de hacer el ejecutable, una vez que lo paso a la pantalla táctil, el Front Panel me queda muy grande.
Existe alguna manera (en propiedades, etc.) para que el tamaño del Front Panel se ajuste al nuevo tamaño de pantalla?
Muchas gracias

Hola,
Si te metes en el menú File -> VI Properties, en la Category: Windows Size, alli marca las dos casillas y verifica que tal te funciona. Cuando estes en el monitor mas pequeño puedes maximizar la ventana o cambiarle el tamaño y los controles e indicadores se ajustaran al tamaño. De experiencia personal te digo que este autoajuste no es tan bueno como uno quisiera, así que si tienes muchos controles y textos agrupados vas a necesitar rehacer el front panel para esa nueva resolución para que se vea tan bien como deseas.

Saludos ricardoe.23,
Gracias por utilizar los Foros de Discusión de National Instruments, te comento que ese tipo de objetos son controles los puedes arrastrar desde el Image Navigator, este mismo se instala junto con el módulo de LabVIEW Datalogging and Supervisory Control, para acceder a él es necesario abrir LabVIEW y navegar dentro de los siguientes menús:
Tools >> DSC Module >> Image Navigator...
Esto abrirá una ventana del Image Navigator en la cual tendrás que navegar por el símbolo que te interese utilizar y arrastrarlo al Panel Frontal de LabVIEW.
Con respecto a tu segunda pregunta, creo que depende un poco de la arquitectura que desees darle a tu aplicación, te comparto algunos enlaces que hablan sobre algunos patrones de diseño básicos que podrían serte útiles:
