Putting frontpanels of sub-Vi's togeter on one Vi front panel

Hi guys,
How to put the frontpanels of my sub-Vi's to one Vi frontpanel? So they are collected at one panel.

In LabVIEW, go to Help >> Find Example... and search for subpanel.

I try to open two sub vi front panel in third - main vi front panel.

I have two sub vi, and I`d like to see this two vi front panel in main vi front panel window. Does anybody can answer me , If it`s possible?

Click here for a recent related discussion.
Or have you thought about using a tab control? You can organize controls in pages and have those controls call sub-VIs with or without displaying the front panel of the sub-VI. See the Tab Control Properties.vi example that ships with LabVIEW.
From any LabVIEW window, select Help from the window menubar, then Find Examples >> Search, then enter "tab control" (without the quotes) in the box labeled Type a keyword to find:

Expanding and clarifying what BJD said;
After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up.
The technique of "create sub-VI...copy" always works for me.
There is one more thing that you should watch out for.
The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node.

Calling vi front panel object update in a running sub-vi loop?

Hello All. I have a calling sub-vi with a "Start Test" button on the front panel. I passed a control reference for that Start button into a sub-vi that runs in a while loop. The while loop is monitoring that Start button and other things.
Problem: Once the sub-vi runs, it no longer takes updates from that Start button. My program never leaves that while loop in response to my Start button.
Is there some way I can make the sub-vi take an updated value from the calling vi?
Attached is the sub-vi (top level, LabVIEW 2011). Please note that I have already tried putting the Start Test terminal inside the loop, but that did not help. I put comments in the block diagram and the front panel to help identify the problem code.
I am going to get around this problem by running this whole vi through a loop in the calling vi, where I can easily respond to button changes. This is mainly an academic or curiosity problem now.
Thank you, Richard V

Lets just whip up a little example then shall we?
The subvi you see contains:
Go ahead and run the top vi. Press OK and watch the value of Value change (up to 20 times per second but that is faster than your eyeball).
Why the difference between this simple example and what you are seeing?
If I had to guess (And, I do since the caller wasn't encluded) I would suspect that you misswired the reference. With that over-burdened connector pane and no required terminals it would be fairly easy to do.
And thats where you might want to ricght-click the vi and deselect view as icon.
You'll find out that its a lot easier to wire the right terminals that way. Also, changing the terminals to "Required" for anything that is as important as an exit condition is a good idea. Perhaps even exit if the reference is null although that should cause an error on the property node. Did you shut off automatic error handling?.... Nope you didn't so there is a valid reference going into the sub-vi. But a reference to what? maybe not the button you think.

I am having trouble stopping a sub VI from the front panel of my main VI.

Whenever I try to stop my sub VI from the main panel i cannot get it to work. It has entered the value of the switch from the main VI and does not update it within the sub VI after it has started the sub VI and hence does not look for a changed value on the switch. Is there any way that I can get the sub VI to check the state of the switch on the Main VI on each loop?
Thanks
Ross H

Hi,
I am including 3 VI programs, here main vi controls the sub vi, i mean sub vi can be stopped either from main vi or from stop button put on its front panel. Also main vi still works incase sub vi is running.
Hope it works. If above does not answer your problem completely, Pl. do write.

Open sub VI front panel in a tab-- Possible?

Well, the question is basically in the subject: Is it possible to call sub VI's and display their front panel in a tab. I do NOT wish to have the front panel in a new window when called.

The answer is also basically in the picture:
You can find SubPanel element in the same palette as the Tab Control container. Place a SubPanel on the Tab Control and wire a reference of the VI whose front panel you want to display.

Open front panel of sub vi when called - how?

Hello,
I have a VI with several sub VIs.
I want some of the sub VI front panels to be opened, if they are not yet opened and if they are called but I want them to stay in the background.
There are two SubVI Node setups: "Open Front Panel when loaded" and "show front panel when called"
Both are not what I want. If I select "show front panel when called", then the front panels are opened but flickering because they are called often and alternately.

Yeah, we've heard that one before...
@smercurio_fc: With your example I can see if a subVI is opened or not, but how can I open the subVI during run time if it is not opened
Just call the method with it set to "write" (right-click and select "Change to Write"). I don't recall if LV 7.0 has a Front Panelpen method. Check the LabVIEW manual.

Sub vi front panel opens when main vi opens

When I open my main vi I have one of my sub vi front panels that opens. I looked in the properties for the sub vi and Show front panel when loaded is NOT checked. Is there something else I need to look at?
Solved!
Go to Solution.

please clarify;
Q1)
The sub-VI FP opens when
You open the top VI but BEFORE you run it
OR
The sub-VI FP opens after you start the top level VI
Q2)
If the above Q was after you run....
Is the sub-VI running or paused when it opens?
If it is puased you may have a breakpoint set in it.

What's the best way to put a programmatically sizeable transparent image onto a VI front panel

The problem is twofold: 1) how can programmatically read a transparent image (i.e. image with transparent background) and 2) how can I programmatically position and size that image onto a VI front panel. The best luck I had with item 2 was with a boolean custom control with an imported image. However, this control does not have a programmatic method for importing an image, so the image had to be manually cut&pasted into the custom control.

Hi,
If the image is static, it's possible. You can drop a metafile on the front
panel, and use Panel>Decorations> to get a reference to the image. Resize it
as desired.
Changing the image (e.g. from file) is not possible this way, but you can
put multiple images on the screen and change the visibility...
If you want to make a picture viewer, I'd consider an activex control (this
way you can load several picture formats without any programming).
Regards,
Wiebe.

How to bring a VI front panel to the front (of all open windows) when the parent VI calls a sub-VI in Test Stand.

In Test Stand when I call a sub-VI front panel, the pop-up window goes behind all the windows and the user just waits for the screen. I want the pop-up to come to the front so that the user can know what to do. I couldn't find any property that I can set which would make the called VI go to the front.

What version of TestStand are you using? Here are the TestStand palettes in LabVIEW for TestStand 2.0 and 3.1. You can also set a VI to be modal in VI Properties>Window Appearance. Select Dialog or go to Cutomize and change the Window Behavior.

Cluster does not populate in sub-vi unless front panel is opened

I have a sub-vi that saves my data to a database and the cluster
containing the data will not populate unless I open the front panel
when it executes. What could possibly cause this?

It is the readings cluster that does not populate. That is the input cluster for the vi. When I run in the development environment the program saves correctly without opening "Save Readings.vi". However after the complete program is compiled the data will not save unless "Save Readings.vi" is opened when it executes. I have attached the missing vis

How to update the variables in sub-vi on main front panel?

You probably want the slide to update while the while loop in the subVI is running, so you can't simply wire an output from the subVI to the main VI. So you are going to have to use some form of communication between the two VI's other than a hard wire. For this simple case I think I would recommend using a global variable. You could also use DataSocket or even write the value to disk, but using a global is probably the easiest method for this case. I've attached your modified VI's. Let me know if this works for you.

How can i upload two different logos for 2 sub sites [which falls under one super site ] in share point 2013 ?

hello,
How can i upload two different logos for 2 sub sites [which falls under one super site ] in share point 2013 ?
thanks,
Jay

Hi,
I understand that it applied first logo to all other sub sites.
Please make sure that you change the logos in the subsites.
If we change the logo in the root site, the logos in the subsites will be changed at the same time.
However, we can change the logo in the subsites separately.
We can go to a subsite, click the Site Sitting-> Look and Feel-> Title, description, and logo->Insert Logo->select a picture, then it will has a different logo than the root site.
Then go to the other subsite, click the Site Sitting-> Look and Feel-> Title, description, and logo->Insert Logo-> select another picture, then it will has a different logo that the first subsite.

LV 8.5 opens all sub-VI front panels

Hello,
Recently I again saw a strange occurrance that has happened to me about 10-12 times over the past year. Here specifically I am using LV 8.5 with the cRIO and FPGA module. When I was running a new RT VI from the developer environment, (deploying to the cRIO) the result looked something like this:
All the sub-VI front panels are opened, and shown in their reserved or running state.
None of these VIs are set to show front panel when called or opened, but all are sub-VIs of the top level VI within the project. It seems to have replicated a "Find all VIs in memory, within the project" and then "Show front panel" Invoke. The troubling thing is that this is not really repeatable, when I have closed all the VIs and run the VI again, it is fine. I have seen the same behavior in LV 8.2, 8.21 as well as when deploying to cFP-2120 or when on a Host computer.
Has anyone else seen this or are there any ideas of what is going on?
Thanks,
Mello

Well now that I have seen to image, I recall having seen this myself.
Like you, it was when I was deploying to an RT target and I was not able to recreate this behaviour.
It was either an 8.0 or a 8.2 app.
So all I can do is confirm that you are not alone, but can not offer a solution.
