A different Front Panel question

Just to spice up the board, I'll ask a different question about the front panel. ?I have the X-Fi Fatalty board with the front panel and for the past 2 years have not used the front panel.
My question: Can I pull the front panel and set it asideI don't use it and the ribbon cable is cluttering up the wiring in my, already cramped, case. ?Will it operate with just the PCI card?
Thanks.

Absolutely. I have used mine many times without the front panel. I add it back when I dont want to reach around to the rear to plug in a MIC and I certainly dont use my headphone jack on my center channel speaker for headphone output.

Different Front Panels on 3 different screens, same data collection

Hi
I'm having an issue on where to even begin with this problem. I would consider myself a novice-intermediate LabVIEW user.
I'm going to be doing some testing at a facility I work at. We need three different front panels running during the testing one in the DAQ room, one in the firefighter tech room, and one in the viewing room. The issue I need help resolving (I don't even know where to begin and have looked everywhere) is how can I show three different front panels on three different screens. We have a lot of equipment going into the system, but I only want to produce temperatures on some, gas analyzers on some, and a red LED in the fire tech and control room (not in the viewing room we don't want to scare people if something goes wrong!). I have these set up just fine and they are working based on the thermocouples I have tested.
I need to be sure the control room can read all of the data coming in, even if it isn't displayed on the screen, and the 3 different front panels are required. How can I do this without having to run 3 instances of LabVIEW? Is there a way I can use S-Video or something, or incorporate subVis to show up on a screen somehow?
We are hooking up to a FieldPoint system as well if that helps. Im using LabView 8.6.
I'm not going to attach the code because it's working, I just need to know how to integrate the three together.
Any help would be greatly appreciated. Thanks so much!

CLD Front Panel Question

I understand that the front panel is now provided to you for the CLD. Is the provided front panel fully functional, or does it require modification?
For example, do properties such as mechanical action and boolean text require modification on the test taker's part, or is the front panel fully functional?
I can't imagine these things taking very much time, but it is good to know what to expect going in.

The folder hierarchy provided to you for developing your solution consists of the (named) main VI, input file (where applicable), Controls and SubVIs folders.
Main VI: This includes the front panel with the corresponding terminals on the block diagram. Where front panel objects are grouped and typed defined, the .ctl file will be provided in the Controls folder. Some functionality may be provided with the controls (for example: Data Entry limits), but it is the developer’s responsibility to check and modify to the needs of their solution. For the main VI, you must customize the following:
Icon: Customize the icon. Recommendation: Use simple icons: Example: . Avoid developing fancy, graphical icons
VI Documentation: Briefly describe the VI in the VI Documentation. See following example.
Description and Tip: Provide either a very brief Tip strip or Description for Main VI objects. Example: “Withdraw funds”, “Check Balance”, “Stop Application”

Application with many Front Panels

Dear all,
I am working on an application which has 3-4 front panels.
Like, when the application starts, the "User Profile" panel is shown. From there i can move on to 2 different panels.
1 panel is for Taking data from the new user. another for taking test of the user.
i want to know is it advisable to display each panel from different VI, or, shud i have them all in a single VI and handle them by making Visible property On/Off.
Thanks,
Ritesh

I think that the best way to do it would be to use the tab control. Place all the controls or indicators for each different "front panel" that you would have on the different tabs and then make the tabs visible/invisible. That way you only have one contol/indicator to keep up with. You could do a search for creating a wizard in LV. You would also benfit by using a statemachine type architecture for this.

"NOTHING IS EVER EASY"

How can I create multiple front panels for a single block diagram?

Hello,
I have developed a VI with multiple controls and indicators that needs to run on computers with screen resolutions ranging from 800x600 to 1680x1050. The problem I'm having is that the front panel does not properly scale for this range of resolutions by checking the options in the "VI properties" option. Is there a way to create multiple front panels of various sizes for my block diagram and programmatically select the appropriate front panel based on the screen resolution?
Solved!
Go to Solution.

See the attached Zip file.
I have two different front panels. Open either one and run it. They both call MainCode.vi which takes the references passed to it and register for events. From there, it does all the work of the code you would have put in your front panel .vi.
This way each front panel can be laid out however you want for each screen resolution.

Set front panel size to fit different monitor ( 2 monitors-pattern to 1 monitor-pattern)

Hello, Everybody,
I have here some questions about front panel size.
At first I have create my LabVIEW programs with 2 monitors and run them with 2 monitors, because of this reason I have created a huge front panel with many objects.
But sometimes I will run the program only with 1 monitor, the problem is, the front panel is too big, I can not see the front panel with all objects completely on one monitor! I know, I can scroll aroud it, but I don´t like this way. I would like to set the front panel size automatically to fit the window ( to differenz window sizes or resolutions), how can I do that?
I have tried with "Maintain proportions of window for different monitor resolutions" and "Scale all objects on front panel as the window sizes" to finish that, but they did`t work, I can not see the front panel at once on one monitor;-(
Can you help me?
regards,
Johnny

As noted in the KB article What Is the Difference Between the Options
"Scale All Objects on Panel" and "Maintain Window Proport..., the "Scale All Objects on Panel causes all the objects inside the panel to scale when the panel itself is resized". If the panel isn't resized, the objects arent's scaled. You may also want to read the KB article How Do I Scale All of the Objects of My Front Panel with the Window Size?.

How to resize the front panel to fit different resolutions

I m using LabVIEW 8.2 on Windows XP SP2
I've tried both “maintain proportions of window for different monitor resolutions” and “scale all objects on front panel as the window resizes” selected but just messed up everything when i switched to another different resolution. It's annoying since I'm using 22 inch monitor to do the coding but the user supposed to run it on laptop or wince.
Any solutions to it?
Thx in advance.

Thank you all. Following is the reply from NI support. I think the best way is to edit vi in low resolution.
One of the easiest ways to tackle varying screen resolutions is to design
the front panel to the lowest resolution that you expect it to run on. It
should then look acceptable on any screen larger than that.
However, you can get a bit more tricky by programmatically determining the
computer's screen resolution and then dynamically changing the size of your
front panel objects. Use an Application Property Node and select
Display>>All Monitors to return the current screen size. Then, according to
the screen size, you can size the control or indicator programmatically
using the Size property node for your front panel objects.
Ultimately, these issues have often been a result of font size issues.
Specifically, this can be a problem when two machines have different
desktop theme/font settings. If your objects are coming out in different
sizes on different computers, you can setup up LabVIEW to use the same font
on different systems by modifying the .INI file.
The easiest way is to do this: use Tools->Options->Fonts from the LabVIEW
GUI. You can then set the system fonts to anything you want. After you
have done this on one machine, open your INI file (it is in the same
directory as the LabVIEW executable) with any text editor and copy the
corresponding entries to another file. Add these entries to the INI files
on any machines you want to lock to font. You will probably run into
issues if you are supporting different platforms (Windows and Mac or Mac
and Linux, for example), since the fonts you want may not be available on
both platforms. There are Windows fonts available for both Mac and Linux
platforms, so this can be somewhat ameliorated.
This is all I can think of, but that's not to say these are the only
solutions. You might check the Discussion Forums, as many of our LabVIEW
Champions have tackled similar issues and offer their expertise as well.
Here's just a few threads that I'd like to refer you to:

Dynamic cluster/array follow up question - front panel

Thanks for the responses to my last question - they were great and fast!
I'm still stumped on how to create the front panel. It doesn't really matter whether it is an array or cluster. It sounds like either way, once I have it I can autoindex through it. The basic application here is that I have a VI that will store one XY plot to our database. I'd like to wrap that in a VI that will take N XY plots and store them all in our database regardless of what N actually is. So in terms of creating the front panel, I tried to create an array control and drop a XY graph in it, but it doesn't seem to like that. It said that I hadn't added an element to the array. I also tried to drop a XY graph into a cluster control and that cleared the broken run arrow, but wouldn't I have to know how many XY graphs are being passed in? It seems like I'd have to put one graph in the cluster control for each graph coming which defeats my purpose? Remember I won't know how many XY graphs are coming into my VI in the array or cluster. Anybody know how I can set up the front panel?
Again thanks for the quick replies!!!
Best Regards,
Steve

Look at the attached VI.
It has a single XY graph inside a cluster container, and that is inside an array container.
With this setup, it wouldn't matter how many graphs you pass to the subVI since it's an array, it will take whatever is passed to it.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

How to save settings in the front panel to different files and retrieve it later?

How to save the front-panel controllers' settings to different files and retrieve it later?
What I've archived is the "Save Settings" function, but when trying to "Reload Settings", I can only retrieve the saved data to front-panel indicators, but not the controllers!
Can anybody give me some advises?

Hi
Just write the retrieved data to a local variable (but make it writable first) or property node of the controls.

How to create a front panel display that lights up with different colours depending on its input signal?

I am doing a project where I have this array which has different voltage outputs for each grid. How do I create a front panel object that lights up with different colours depending on the voltage input or is there already such a pre-built function?
In addition, I wish to display these in an array on screen. Is there any pre-built function for this?

The simplest way would be an intensity graph. It gives you a 2D grid where each grid point is colored according to the value of a 2D array. The Z axis color ramp determines the color.
My second choice would be an array of colorboxes. (They could even be made to look like LEDs (see image, if course you can leave them square too), All you need is a scaling function thap maps voltages into a color ramp lookup table with an 8bit index)
(Using booleans and color property nodes is relatively clumsy. Booleans are meant for two states because the value is boolean. Since array elements can only differ in value, and not in properties, it will not even work. Color boxes have a color data type which is much more appropriate for this case)

Question on closing Front Panel references

I'm manipulating controls on the Front Panel of my VI. In doing this, I open a slew of references (to the VI, to the Front Panel, to its Panes, and to the objects on the Front Panel). Normally, before exiting the VI, I carefully close them (in LIFO order, of course), but a question has arisen:
I want to "export" a series of references to Boolean controls for use in succeeding VIs. No problem, while enumerating the controls (see above), I simply identify the Boolean references and build them into an array that I pass out. First question -- does anything "go wrong" if I also do a "Close Ref" in the main loop (after adding the reference to the array, of course)? [At present, I'm only doing a Close Ref on the non-Booleans]. Logic says this should be OK, as the Close Ref is mainly doing "garbage collection", and I've done a "copy" operation in building my array, but to a persistent structure.
Second question -- in my "cleanup" routine, I noticed I was "double-disposing" of the references, that is, I did a Close Ref on my array of Boolean References, but also was enumerating the entire Front Panel (as I did when I opened it) and disposing of the references that it found. Again, this should be no problem, but (in principle) I'm doing a Close Ref on two references to the Boolean control. It occurs to me that this is not really logical either -- I should be able to simply "abandon" the array of references -- although it takes up memory that can be "reclaimed" for other uses, the fact that it is an array of RefNums is a "so what" -- the contents of the array could have been a numeric or other "solid" data type.
Does this make sense? To summarize, what I'm trying to do is to "extract" some RefNums to Front Panel objects for later use. In the "extraction" process, I must open (and create references to) multiple objects, including RefNums to my "objects of interest". What I think I can (and should) do, once I've copied the RefNums I need, is to dispose (Close Ref) all of the RefNums that I opened during the extraction routine, and do something equivalent when I do the subsequent "cleanup" (which undoes any modifications I made as part of the extraction).
Comments welcome.
Bob Schor

I usually store the ref. at the beginning of my program, in Functional Globals, and i close them when the program does not need them any more.
I think this is the right approach. And it is simple

3 front panels on 3 different monitors

Hey all
I was browsing the web and the developers forum but nothing seemed to help me with this problem. I have three front panels I need to run. I have a control room .vi (which is still in the works) a fire tech subVI and a viewing room subVI. I need to show the Fire Tech and Viewing room VI on different monitors.
Now when I say monitor I literally mean like a TV screen. The only computer available in the desired space for testing is in the control room. Therefore I somehow need to get the Fire Tech panel in the fire test area and the Viewing Room panel in the viewing room. Is there a way I can do this without using a web browser? Maybe there is some sort of S-Video I can use or something I can wire from my computer to the other monitors.
Any information would be great. I looked into the web browser thing like I said and due to the confidentiality I don't feel comfortable using it. I'm not sure how remote panels work, but like I said I don't have computer access other than the control room.
Thanks

Hi Tanya,
as there are graphics card available which support up to 6 monitors your 3-monitor request should be possible from the hardware side.
In LabVIEW you can control on which monitor the frontpanel is opened, just look for the "FP Window.Monitor" property of the VI...

Adjust front panel to screen size and re-position objects on different systems automatically

Hello, i have designed a vi that contains 5 led's placed at the 4 corners and center of the front panel which occupies the entire screen. However, this vi is to be used on different systems having different screen sizes. But on every screen, i'll need the front panel size = screen size and the led's to be placed to the centers and corner of this new screen size automatically without any manual operations and positioning bieng done every time. Will the resize option perform this task completely or do i have to go for some other techniques?
Solved!
Go to Solution.

As far as I know, what you want is not easy to do but it is doable but you have to programmatically do it (no Labview setting). Here is an example for only 2 LEDs but I suppose that you will be able to make it work for your other LEDs.
This VI maximizes the front panel and then positions the 2 LEDs in the center and top right corner upon running. The LEDs are positioned according to their own top left corners, not according to their centers.

Scaling front panel objects for different screen sizes

Hi,
Can anybody help me of designing Vi for different screen sizes. I have designed a VI for a monitor of small size and lower resolution but when I open the same Vi on a different monitor,objects are not aligned properly. The properties which I have changed are
Window appearence->Default
Window Size -> Panel size 0,0 & Tick marked options of Maintain propotions for different monitors and scale all objects
Window Run Time position-> Maximum

Imran,
I can't solve your problem entirely. However when I have to write a program that will be deployed on a variety of monitor sizes, I tend to set the size of the Front Panel to suit the smallest monitor, and then remove the ability of the user to resize it.
Also, set it to run in the centred position.

Same object size (front panel) with different screen resolution

Hi everybody,
I realised an application, and I try to instal it on various computer. The probleme is that they haven't the same screen resolution, so the front panel is not the same on each computer. It is possible to build an application which have the same front panel with different screen resolution ?
Kriss.

Hi Krisss,
switch off any "adapt to screen resolution" switches in the VI properties...
You should also define "same front panel" and "same object size"! Do you mean the same pixel size or size in mm or size in percent of screen?
