Required connections to sub vis automatically

I remember some radio button to make connections to sub vis automatically required. Unfortunately i don't find it anymore. Can you give me a hint?

Is this what you're looking for?

Is it possible to unlink sub VIs to prevent affecting other projects

We are running a validation with different flavours of the same IC which require using the same set of VIs with slightly different settings. In order to avoid confusion for users who are running with one type of silicon we have decided to make a copy of the LabVIEW code in a different area of our project folder on our network. We are concerned that LabVIEW will still find VIs from, say Project A, and use them for Project B, which may or may not cause problems when re-running tests for Project A as some of the VIs may need to be modified for Project B.
We have looked at creating different sub folders and unmapping network drives but are still concerned that LabVIEW will be smart enough to find the Project A files when it should pick up the Project B files. The issue is that we may need to edit some of the VIs for Project B but don't want them to be modified for Project A.
Is there a "One-click" method of unlinking all sub-VIs for Project B and when we load the main VI for Project B we can then manually point to the correct files so that Project A will not be affected and we can still run the VIs for Project A in the same environment with the same network drives mapped?
This is complicated to explain so let me know if you need clarification.

I don't think there is an automatic way of doing this. (someone else may know better)
I would do a "save as" on the project, duplicate all files elsewhere, then add a prefix to all of your VI filenames.
I tend to do this for projects that re-use old code too. Add a project specific prefix to the VIs and then if I decide to modify things in the new project I don't break old code.
Edit:
Another thought: If it is just settings you want to change rather than the actual code, maybe you could use a config file of some kind to load in the values that are going to change with your different setups. Then you use all the same VIs but just change the config file between different setups.

Using Open VI Reference to run a VI, on an RT target, with sub-VIs not loaded

I've been using Open VI Reference and Call By Reference Node to remotely run VIs on my RT controller. I
usually wire string data to the vi path input, but this
requires the VI to be in memory. I understand (from LabVIEW help) that I can wire a path to this terminal and specify a VI that is
not in memory, but is on the disk. NI has an example that
confirms my understanding. I get errors when I attempt to do the same
with VIs that have sub-VIs; I suspect that the problem is that
the sub-VIs aren't in memory and that the top-level vi doesn't know where to
look for them (because the paths aren't specified). All of the sub-VIs are on the RT system (in the same directory), they're just not in memory.
Is there a way to get LabVIEW to look for sub-VIs on the disk? I don't want to rely on using a startup application and rebooting to get my VIs into memory.
Thank you,

Hi Jim,
It sounds like you are going about calling VIs remotely the correct way. It would be very helpful if you could post the errors you are receiving. I also wanted to know if you saw the note at the bottom of the article that says your VI library must contain everything your top level VI calls.

Show front panels of sub VIs when running a EXE (build application)

I've created a exe file and it works fine. However, it only shows the front panel of main VI and I can not open sub VIs (it looks like they are all hidden). I know it can be done by creating a library file along with this exe file, but that's not what I want. I want to create a single exe file that shows several front panels, and that can be run with run time engine. Is there any way to show front panels of sub VIs by running a exe file?

In the development mode, how are you displaying the front panels? Did you right click on the subVI and select SubVI Node Setup and choose 'Show Font Panel when called/Close afterwards if originallly closed' or did you choose the same options from VI Properties for each subVI. If the second, then the app builder will automatically retain the front panels of the subVI. If you chose the first option or if you are using VI Server to open a front panel, then the default setting in the app builder is to remove the front panels. You would then have to go the VI Setting tab in app builder and edit the settings.

How to creat multiple sub VIs'

I have a VERY large VI that finaly crashed due to the large size. What is the best way to create "Sub VIS"? I have almost 800K of code. Should I create all the sub vis and then add them to my Project? I want the program to call the sub vis automaticaly.
Thanks
Philip

Hi Philip,
Backups:
As Lynn (johnsold) said, local backups are a minimum requirement.
A service like Dropbox is better in case of computer crash.
Note: Temporarily disable Dropbox syncing when doing builds in a Dropbox folder as this may cause builds to fail.
The best solution is true source control like the free TortiseSVN.
For sub vis I suggest:
Identify code sections that perform one specific function. This makes a logical sub vi. If you can easily come up with a name to describe the
section (like "Parse Input String" for example) then you are on the right track. With some practice you will be creating sub vis that can be used
in other programs and save you time in the future. This is a good reason to NOT include unrelated code in a sub vi just because it will fit.
Take note of the number of inputs and outputs in the code section. Ideally you want a small number of inputs and the same for outputs (3 or 4). Use clusters to reduce the number of I/O items.
Standardize on a connector pane layout - this makes wires line up better. The 4224 pattern works well. When LabVIEW creates sub vis it only creates the number of inputs and outputs that are required. So you will normally have to change the connector pattern and rearrange the controls and indicators every time you create a sub vi.
Include error in and error out in their standard places even if you don't need them for the particular application. When you use that sub vi later
you may need them.
Good practice is to use Type Defines for controls and indicators that go to more than 1 place. In your case, it is a jugement call if it is worth the trouble to do this on an existing program. Once you start using sub vis more, Type devs become very important. If you don't use them, changing a data structure will require manually changing every sub vi that uses that data structure.

Here's a quick example I threw together that generates a sort-of-bell-curve shaped data distribution, then performs the binning and plotting.

My ipod touch says "activation required, connect to itunes" i restore it on my itunes and it seems to be working, after i tried connecting to my wifi but no luck, i reset it and the same thing happens all over again. Help!

my ipod touch says "activation required, Connect to itunes" i restored it with on my itunes and it seems to be working again, after i tried connecting to my wifi with no luck i reset it, and again it pops back "activation required, connect to itunes" i restored again, its a non ending cycle, and it makes no sense having my ipod and i cannot connect to the internet with it, can someone please help with this issue?

Maybe here:
Restore loop (being prompted to restore again after a restore successfully completes)
Troubleshoot your USB connection. If the issue persists, out-of-date or incorrectly configured third-party security software may be causing this issue. Please follow Troubleshooting security software issues. .
Next would be to make an appointment at the Genius Bar of an Apple store.

Why is it that when i upgraded to ios 6, my ipad 2 no longer connects to known networks automatically

why is it that when i upgraded to ios 6, my ipad 2 no longer connects to known networks automatically?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Creating sub vis and projects

Hi,
I am currently working on a project which involves a large chunk of Labview programming. I am new to Labview but am relatively experienced with C. I have designed an algorithm for C that I am currently trying to "translate" into Labview. The algorithm I have designed is a very modular piece of code, I have used a lot of smaller functions and called them in main rather than writing the entirety of the code in main.
My problem is that I don't really understand the difference between Labview projects and using one main VI to call other subVIs. I am unaware of whether I would be better off using sub VIs held together in one main VI or would I be better to use a Labview project. I am on a very tight schedule as it is a rather large project so I don't have a lot of time to experiment with my code-writing.
Does anyone have any advice on which approach is better/easier for an inexperienced user or if they are both pretty much the same?
Gillian

Projects and subVIs are completely unrelated concepts.
The project is a means of organizing all the parts of the system you need to develop a program and build it into an executable.
A subVI is just any VI which is used as a part of another VI.
You need both. When you open LabVIEW to start writing your code, create a new project and then keep your main VI and all subVIs and other parts like customized controls in the project. Since you are an experienced programmer and have a modular design for the implementation of your algorithm, you can move those concepts directly to LV.
SubVIs should be logical groupings of code such as the smaller functions in your algorithm. The entire algorithm could be contained in a subVI which has those functions as subVis in the algorithm VI.

My ipad mini loses Internet connection every time it automatically locks.

My ipad mini loses Internet connection every time it automatically locks. I have to re-establish the connection but sometimes it would take too long for the Internet to be connected. I'm using a wireless connection

just browsing around I found this question. Also on my mini retina I fight with this problem. After a lot of searching I found that the only solution is to switch to
Airplane Mode, wait few seconds and switch again.
Or, if you are lucky, to find a Genius who replaces your unit. Cheers

How should I share a cluster across several sub .vis? Best practices? Current problems...

I'm trying to share a cluster across several sub .vis. I've written a save / load settings function that basically stores these settings in a static variable (full .vi attached):
Questions:
1. Is this an appropriate practice? (using a sub vi to share data)
2. My program settings appear to be lost occasionally and reset to their default values. This bug is rare, and it's hard to see what's causing it. Could this be caused by my "save / load settings"? Would this .vi result in race conditions or something weird if I use it in many places (and sub vis)? I've disabled reentrant execution.
The "save / load settings" vi above uses a sub vi to initially read the settings from a binary file and save them each time they are changed (saved). I initialize the "save / load settings" by loading the settings from text the first time this function is called.
Thanks!

What you are doing is generally called a LabVIEW 2 Style Global or an Action Engine. It is a valid way to store data for use across subVIs. Rather than use first call why not have a specific action to initialize the data? The code is a bit more readable. Though you can use first call as you have.

Running two sub vis in parallel

I need to run two sub vis of a main vi simultaneously in parallel.
one sub vi is to run a demo and the other subvi is an application.The demo should run as a small window and the application should run in background

As i said
"If you have the demo vi as floating and the other vi as Default (not floating), the demo vi will allways stay on top"
If you still have problems, just post your vis, (without any unnecessary code), or ask something specific
