How to/Is it possible to get the front panel's VI icon?

Hi
I want a sub-vi to get the front panel's VI icon image of other VI,
example, the subVI can have the image return based on VI refnum, is
there any function to do this? I try to search the "Application
Control -> Property Node" and could not find any of it.
Thank for any suggestion.

This method also exists in 7.0

Is there possibility to use the front panel without installing Labview?

Hallo,
i have two small questions:
1- Is it possible to use the front panel of a labview software without needing to install Labview itself? i mean something similar to the "power point viewer" which can view the Power Point files without installing the microsoft office.
2- In an intensity Graph, how can one change the color?
thanks.

Hi,
Regarding your questions
1)You need to have Labview and Application builder installed on your machine. If you have that you can make an stand alone application (EXE) and then you can deploy it on systems that does not have LabView and can view it, However you will not be able to see the block diagram.
Here is a link that explains how to do so
http://zone.ni.com/reference/en-XX/help/371361A-01/lvhowto/exe_ex/
2) You can either do it by using propery node or marker method. The following link explains it

Show 30 different channels without getting the front panel too crowded

What function should I use to receive the data of 30 channels without getting the front panel crowded? I´ve already done 30 controls simulating the multiplexer in the front panel, but how can I choose each channel in a way that the data from only this channel appear as I click in that control in the panel, and I can change that as I want during the acquisition.

Instead of 30 controls, always use an array of controls. This often simplifies the code dramatically. For example, here's a quick rewrite of Randall Pursley's example above using arrays (LV 8.0). The code is about 10x simpler.

How do I get the front-panel to pop to the front of the screen?

I have a program that is reading in some network files. When a certain part of the file has been changed I want to pop up the front panel and blink the changed area. The blinking is easy and I can get the VI to pop to the front of any other running LV stuff (using the IsFrontmost vi property) but I need the vi to pop to the front of the entire screen and whatever else is running (Excel or the such). Any ideas on this? I'm doing the development on LV 6.1 on Win2k.
Thanks,
Gary

Hi Gary,
There is one thing I think you may have to do. If the window is minimized than it will try to make it topmost but the minimize will take precedence, so you will see the task bar blink and the OS stays in the active/current window. Try to use the "restore window" vi before trying to make it topmost. That should work.
Also make sure that, the LV window you are trying to restore and make topmost is not superceded by another LV modal window.
Thats my take, Let me know if that works, for future reference.
Good Luck
Mache
I've tried putting in the Restore Windoe vi and the results are the same. Both of those functions (seperate or together) result in the window moving to the top of the other LV screens only. If I have Word or explorer or anything else open, that window will stay on top and the task bar flashes. Can I use the "move window to front" vi in my main vi to move my main vi's front panel to the front? If not are there any ways to get around this? My program is mostly running in the background but when there's an important change I need it to move to the front and take precedence for a few seconds.

Is it possible to have the front panel on the iPad 2 replaced with a different color?

I have a WiFi-3G verizon 64GB BLACK iPad 2, when I bought it, black looked the best at the time. but now, it seems that white looks ALOT better and actually makes the screen look bigger . I was wondering if it was possible that if the front glass (not the LCD) can be replaced with a white one. As far as i can see, all of the connections and clips SHOULD clip into place just like the black panel. there should be no problem. the only problem i could see is that the apple store will refuse to install it because of some bullsh** reason. If that happens, i will buy the panel, then go to iFixit or something like that and see if they will take my money. So if anyone can shed some light on my situation, that would be GREAT. THANKS

my step mother got an ipad against my advice to wait for the new ones and she got a white one, and seeing how clean, pure, open and free the white one seemed compared to my black one, which (athough i polish habitually) look sad, dark, grimy and "trapped", i wanted to get the panel swapped. i thought i could maybe pull off an "oh crap i 'accidentaly' dropped my ipad and the screen broke" but that seemed utterly useless as they would just replace it with a black one.

How can I make an area of the front-panel have scroll bars?

I'm writing a VI that provides many options to the user. The front-panel is large and contains many controls ~130 of them, it's divided up visually to match the workings of the system the VI controls. One particular functional block has very many control options though these are rarely used. I can't fit all of the controls I need onto the screen area I have available.
What I would like is a way of making an area of the screen with scroll bars on it. I don't need any more than that, just an expansion of the front-panel area I have available. The "Sub-Panel" feature provides the scroll bars. But, a Sub-Panel is a way of accessing another VI, I don't want to do that. I could put the extra controls on the far-left or far-right of everything else and get the user to scroll the main scroll bars at the edges of the screen. The problem with that is that I it would mean couldn't lay out my front panel to match the system block-diagram as I have so far.
Does anyone know how to do this?
Solved!
Go to Solution.

I know I can show the scroll bars at the edge of the VI. In my case that's not very useful. The front panel shows a block diagram of a system. It's made up of a set of clusters which control various parts of the system. I want to keep this layout because it's very useful in explaining to people new to the system how it works. I inherited that approach from a previous iteration of the program for an older system. The problem I have is that the new system has far more control parameters for one of the blocks. Unfortunately it's one of the blocks in the middle of the block diagram. If it were one at the left, right, top or bottom it would be no problem because the main scrollbars could be used.
I can use a tab-control, that's my fall-back plan. The problem is that would be abusing the purpose of the tab control. In a tab control each tab is supposed to deal with a group of controls that have a common connection. So, all the things in tab #1 are supposed to be connected in some way and all the things in tab #2 are supposed to be connected in some way. There not supposed to be a way of gaining more screen space.
The controls I'm dealing with are numeric controls, switches and rings.

How to: display large error note in the front panel?

hi guys,
When "error out" has an error, I would like to display HUGE RED TEXT in the FRONT PANEL saying: "STOP, ERROR DETECTED!" )
How to do that?
Thanks for your help.
Solved!
Go to Solution.

Place an indicator on the panel. Set the text to HUGE and RED, and set its value to "STOP, ERROR DETECTED!". Make it not visible. When you get an error, use the "Visible" property node to display it.
To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

How do you control LED lights on the front panel to identify the number of steps a stepper motor has taken?

I am controlling a stepper motor that is coupled with a valve with four outlets (using an Arduino). I've got a general understanding of how to control the motor, but I want LED lights on the front panel to light up that indicate which outlet the valve is currently at after the steps are taken. The method I'm thinking about involves a lot of repetitive code. I'm not that experienced with LabVIEW, I'm assuming I need some sort of loop structure but I don't know how to set it up in order to control the sequence of the LEDs. I've attached my current block diagram for a visual aid if needed.

I was thinking about using the Stepper To Go and Stepper Write functions four separate times, using the same constants for the steps each time since the distance between each outlet is equivalent. The only difference would be what's connected to the "steps remaining" node, which would be the function that activates one of the four LEDs (if that makes sense). I was thinking that doing it this way would be a little counterintuitive since the only thing that needs to be changed is the LED indicator.

How do I center and/or maximize the front panel on every event?

Hi,
So basically I have a little issue with trying to maximize and then scale back a VI's front panel every time a user selects a different option from a ring control.
So far i've been using the LVWINUTIL.LLB and the provided window size vi to set the size I want on ring selection change which works fine, but as far as centering the VI goes, the method I'm calling only works the first time. After it maximizes and I select a different option on my ring control which is linked to a case within a while loop it simply resizes to the size i set which is correct but when I got back to the ring case which is supposed to maximize the front panel again, it doesn't do it. Centralizing the FP also only works once.
I'm using FP.Run-Time Position.Centered to try and center the VI....only works once. I do understand that this might be the desired behavior since the name is run-time position meaning it'll only do this when the VI is first run, however I need this to happen more then once, how can i do this? Thanks...

How did you center the FP?
Their a method that should work time after time.

How do I print a part of the front panel?

I am interested in printing a part of my front panel as one page instead of printing the entire front panel. Does anyone know if this is possible? Thanks!

Hi Nes,
This is the second time you are posting a variation on this question.
I was about to so NO YOU CAN'T...
but then I thought...
It is possible to print just parts of a front panel but it is a lot easier to do the things others have suggested.
If you really want to print just a part of the FP you will have to do a lot of coding and the GUI will do some strange things in the process.
I will outline the process and leave the code as an exercise for the reader.
Using property nodes determine where on the FP the objects of interest are located.
Again using property nodes, move the objects around on the FP so that they are grouped together and sized such they fit on a printed page.
Using property nodes adjust the screen size origin etc so only
the objects of interest are now visable.
Using.....nodes print only the visable part of the screen.
Using....nodes put everything back where is was when you started!
Like I said, this is not easy.
The simplest solution was suggested by BJD who said group the objects of interest on a tab page, use an invoke node to get the image and then display it on the FP of a sub-VI set to print on completion. That method will let you quickly add new interesting objects to the print out without having to change the sub-VI.

It is possible to open the front panel of a subVI more then one time at the same moment?

I want to open a subvi´s front panel several times with each one operating independently. The subvi has a ring with several variables to choose to show in a graphic. The subvi is called from a button on the Main Front Panel. It is possible to, for instance, open the subvi and set it to show a temperature graphic and click again on the button to call another instance of the same subvi and select pressure for the graphic, keeping both new windows side by side? Will I still be able to access the Main Front Panel?

Yes you can. You have to use a .vit (VI template file). There's an example here. There's also been lot's of discussion on the subject. I think if you do a search for vit, you'll be able to find additional information and examples.

How to display some html code in the front panel

Hello.
I am trying to properly display a few lines of html code in some kind of indicator on my front panel.
I was trying to use an ActiveX container with MS IE in it, but all the methods I find are to make it navigate to a given URL. I did not find any method or property by which I could give it some html code and it would display it.
Anybody know of a way to do this? It does not have to be using ActiveX or MS IE.
Thanks in advance,
Alejandro

Here is a simple way using the activeX that I have embedded in some programs in the past. You will have to call the file path to show the file.
Hope this helps some.

How to send 20 individual pictures to the front panel ?

Hi LabVIEW experts!
I have a lung simulator which I connected to the Ni 9205 and could read voltage from. I wrote the program and it works well. I want to use this program for taking an exam of some trainees. Now I have a problem. I need the trainees to look at the graphs and when they want additonal information by pressing a button, a picture of an xray or lab data related to that patient shows on their monitor. Case by case is different. I have for example 20 lab data from different patients with their xrays. How can I control the trainee program to send a picture which is related to that patient?
Thanks.

Yes.
You just need to have your LabVIEW code programmed to do that. You can convert the picture data to a stream of bytes (look at typecast or flatten to string) on the sender. Use TCP/IP functions to send the data over the network.
The receiver will do the reverse (typecast back to an image, or unflatten from string) and send it to the picture indicator.
Look at the functions
I would recommend looking at the online LabVIEW tutorials
