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 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

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Also make sure that, the LV window you are trying to restore and make topmost is not superceded by another LV modal window.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.

A control that would allow the choice of different VI%27s from the front panel%3F

Hi guys,
I am fairly new to Lab View and I have made a few VI's for my coursework. From the control panel i want a control that would allow me to toggle between the different VI's. I have looked at the ENUM function but it doesnt quite do it for me. Any suggestions about any functions or tools would be much appreciated.
Regards,
Jack.

Hi jack33,
- Any idea why Enum function doesn't suit you? So, that we can have better understanding of your problem.
-Quick suggestion would be to use, enum or menu ring and simple case structure.
-The other idea is to have an event structure and bunch of boolean controls for each vi and open them in appropriate events.
Thanks

How can we get an image of selected area of the front panel

i am plotting some graphs and want a group photo of all those in one shot is it possible????
n i want to get the graph coordinates on the mouse click.....
i.e when i click on the graph at any place the values corresponding to it must be retrieved. how do we do that,,...
i have tried with the labview help but didnt get any help
help please????????

Here's a start. This will get the front panel image and display it as a picture indicator.
You could use an event structure to capture the mouse clicks on the picture control to set the image area. Then using the mouse coordinates (referenced from the image coordinates), you can get the image subset "Get Image Subset.vi".

How to synchronize presentation on the front panel to the start of a 75Hz monitor's retrace cycle?

How to synchronize front panel presentation with the start of a retrace cycle of a 75Hz Monitor, so when a bitmap is presented 100ms, its duration is indeed 100ms on the monitor?

Hi,
In the old days (late 90's), we used in port and out port to wait for
vertical retraces (or even horizontal retraces).
I searched the web (vertical retrace), and there seem to be lots of
infromation and tools, like
http://www.compuphase.com/vretrace.htm
It uses a simple routine:
mov dx, 3dah ; VGA input status register
vretrace_loop:
in al, dx
test al, 8 ; bit 3 set?
jz vretrace_loop ; no, continue waiting
But to get it working, you need a VxD. Good news is you can download it.
The also suggest you use WaitForVerticalBlank(), but dx could be hard to get
working under LabVIEW.
Please let us know how (and if) you got it working with LabVIEW!
Regards,
Wiebe.

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

Trouble getting a subvi to update a graph in real-time on the front panel

Hi All,
First post here, so play nice =). I am trying to update a graph on the front panel from within one of my subvis, however it does not update it in real-time. It will only show the completed graph after the subvi finishes running. I have tried to use references/property nodes and I have also tried using my chart as a global variable, but neither of those methods have worked (I am probably doing it wrong). Can anyone provide a detailed walk-through of how to do this using either one of those methods? Or perhaps even a different method?

ModusPwnens wrote:
This is how you do it, right?:
Try this for a quick demo of the reference method:
Create a VI as shown in the image.
Select only the while loop and do "edit...create subVI" (as shown). (you will get a subVI that contains the needed connectors and is alread wired to the reference)
Run the main VI, and the chart will update every 200ms.
Note that this is only a draft and many things are missing. (For example, the subVI cannot be stopped at the moment. Also, you want a graph, and not a chart.)

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

How do I test a scenario without getting the other party involved

Hi,
How do I test a scenario without getting the other party involved?
I have created a scenario to receive information from an external system (Remedy), processing through a SoapAdapter into SAP to create a service order. How can I send a sample of information in order for me to test my scenario without asking the Remedy people to transmit data all the time?

How to run a subVI without poping up normally, but when clicking a button, popup the front panel?

I know pop-up the front panel of a subVi when called by selecting VI Properties>>Windows apperence.
But what I need to do is: always run the SubVI inside the parent VI as the nornal subVI do without poping up. But when I click a button"show front panel", the SubVI popup the front panel.
Is there anyway to do this?
Thanks,

ossoo,
You can use a static VI reference to the subVI and then use the Front Panel Open invoke method to show the front panel when you want. I have attached two VIs that show this. I saved these VIs for LabVIEW 2009 so you should be able to open them up and run them in 2009 or later. Add.VI is the subVI that you are calling. The Caller.VI is just a While Loop that contiually calls the Add subVI. Inside of the While Loop is also a Case Structure with a Static VI Reference (you might need to change the path this is pointing to after downloading the VIs to your computer for this to work) and the Front Panel Open invoke method. You can run the Caller.VI and interact with the main Front Panel as normal and see the subVI but then you can click the Open subVI? boolean button and it will open the subVI's front panel. You can continue to interact with the main front panel and see the values update on the subVI's front panel as well. You can just close the subVI's front panel when you are done viewing it. Does this help?

Hi. We have two iphones and one Itunes account. How do back up each one without getting the others contacts

Hi. We have two iphones and one Itunes account. How do back up each one without getting the others contacts and without syncing each phone to each other?

Welcome to the Apple community.
Ideally you should each have your own iCloud account, providing you with your own contacts, calendars etc, not doing so will result in exactly what you have experienced. The contacts have likely been lost due to the options you have chosen at the login stage on each device.
Unless you have the missing contacts in a backup file, they won't be recoverable unfortunately. You can add them manually to the contracts that already exist and continue to share the iCloud account if you wish, but I suggest that you each have your own iCloud account.
Note, you can each have your own iCloud account, but continue to share an iTunes account for purchases of apps, books, music, TV shows etc etc.

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:
