Hide front panel bars at open

Good morning,
Is there a way that I can hide the FP title bar and menu bar etc… at open? From the VI Properties, I can hide them at run time. But I would like to hide them at Open. I have a running main vi, it opens and runs another vi(code is attached). The main vi is run with full screen and hiding title, menu bar etc… I need to have the secondary vi run full screen without the bars as well. If I make changes in VI properties setting, the bars will disappear at run time, but I can see the bars flashing before they disappear. Any idea on how to accomplish this? Thank you for your help and time!

What I would do, if I'm understanding you correctly, is don't show the window when you call the VI (this can be set in VI properties; uncheck the box to show front panel when called). Then, in your code, set the windows properties using property nodes and after they are set programmatically show the window using a property/invoke node.

HIde Front panel - enjoy Ctrl-Key shortcut

It is not a question, it is a link to a good old idea:
http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Allow-ONLY-the-Block-Diagram-to-be-opened-Without-Fron...
and Ctrl-Key shortcut attached.
Shortcut hides (including taskbar) and restores front panel window.
It always activates block diagram after all:
If you use shortcut with the hidden FP, it will activate block diagram (unlike simple Ctrl+E activates front panel)
Attention! It will be hard to find VI, if you have hidden it's front panel and closed block diagram - that is why we still need this to be integrated into LabVIEW
PS Use: Place into C:\Program Files\National Instruments\LabVIEW 2011\resource\dialog\QuickDrop\plugins and set shortcut in VI Shortcut window (Ctrl+Space -> Shortcuts -> Ctrl-Key Shortcuts)

Hide front panel.vi ‏19 KB

It is a custom quick drop shortcut: Labview description is here:
http://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/qd_keyboard_shortcuts/
Place the vi to C:\Program Files\National Instruments\LabVIEW 2011\resource\dialog\QuickDrop\plugins
Next time labview launches, it will be available, but you need to set a quick button for it:
Press Ctrl+Space, it will open Quick drop window.
Press Shortcuts..., switch to Ctrl key shortcuts tab (see picture)
Set the button (E) for the selected plugin vi.
Next time you press ctrl+space, followed by Ctrl+E, LabVIEW executes plugin vi.
Correction for my description: if the front panel is hidden, closing block diagram closes the vi (with confirm dialog, as usual). This is not a problem

Hide front panel when opened

I have a VI running as a back ground task (VI_A) to the main VI (VI_B). VI_B starts VI_A and the idea is that VI_A will be minimised on startup. There is a button on VI_B to restore the window and a button on VI_A to hide the window and return to VI_B.
This is all working OK, I open VI_A front panel when called, VI_B minimises VI_A straight away etc, I am using the WINUTIL.LLB functions to perform this. The problem I have is VI_A front panel is visible upon start up for a couple of seconds (there is no real delay in my execution to minimise). I have tried setting VI_A to be at teh back within VI_A but still it appears at the front for a couple of seconds.
Does anyone have any suggestions as to why this is occuring.
Cheers,
Wayne

One thing that you could do is to change the Windows Appearance property to NOT open front panel when called. You can then have your main VI (VI_B) open the panel for VI_A as before, but it will not start with the panel open. If you are creating an executable, go to the VI Settings tab page and click on the line with VI_A and then Edit Settings. Turn OFF the Remove Panel property. This should work for you (I've done similar already anyway).

Close front panel but leave open block diagram

Is there a way to do this? I would like to have my block diagrams of a few subvi's open but front panels closed so my task bar isn't so cluttered. It's not a big deal, I was just curious

How to hide front panel objects behind other front panel objects

Hi,
I need tho change an existing project and to make it simple just want to hide some front panel objects behind others. But I can't find how to put the one I wnt to the front hiding all others. So now there are some in front that should be hidden.
Is there a button or menu item "Move to front / back" like in many other programs?
Thanks
Martin

Hi Martin,
what about the link I provided in my previous post? What else do you need?
What about the chapter "fundamentals" in the LabVIEW help?
Going the way "Fundamentals -> Building the FrontPanel -> How-To -> Reordering Objects" seems rather logically to me…

Hide front panel when running

Who knows the way to hide a VI's panel when VI is running?

Hi Ronin,
The reason that your Front Panel property node is no longer working is that the Current VI's Path VI is returning a different path for your executable than it did for your VI. There is an excellent KnowledgeBase which describes this issue and how to work around it: Functionality of Current VI's Path Depends Upon Execution Environment.
By the way, in the future you will have much better luck getting replies if you create a new thread--this thread is three years old

Application front panel takes long time to open

I have an application that will open quickly on one computer and takes a long time on another. What is happening is the icon is displayed in the task bar but the front panel will not open for some period of time. Both computers are running Windows 7 and the application was built in LV 2010. The applications main purpose is capturing images from a USB camera. The communications to the camera is done using .NET components that were developed by the manufacturer of the camera.
I was hoping somebody could give some ideas on where to start troubleshooting?

I've had this exact issue on a computer that couldn't access the network.
It is because .NET is trying to access the network. Can you run this application on a computer connected to internet ? I believe you have to uncheck some options
Control Panel --> Internet options --> Advanced
I believe the three I unchecked were: "Check for Publisher's certificate revocation", "Enable Integrated Windows Authentication", and "Check for Server certificate revocation". I am not sure about the exact 3 I unchecked, but give it a try. Good luck !
Kudos always welcome for helpful posts

How can I hide the main front panel when I run from the executable?

Hopefully this is an easy question. I have an application where the front panel is not the main GUI and I would like to hide it when the program runs, but only when it runs from the executable. How can I do this?

NIquist wrote:
Yeah, don't do that. Executables built in LV require at least one front panel to be open. If it isn't, the run-time engine automatically closes the executable. I haven't checked recently, but I assume this is still the case.
Instead, you can set the FP state to minimized (as suggested earlier) or (better) to hidden.
P.S. one side point - the property and invoke nodes have a shortcut - if you use the Application or VI classes and don't connect a reference, they default to the current app or VI. That means you don't have to open the reference.

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.

No, no issue with my code :-)
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.

Can not open front panel sub VI when running an application VI.

When I create an application of my program a problem occurs. When I select options (press a button or so) from the main front panel that should result in a popup menu (sub VI cal) LabVIEW indicates that something is happening but the front panel does not open. The mouse indicator changes to the time glass so LabVIEW is doing something but the window of the sub VI does not open.
The problem has the same characteristics on several places. There are some sub VI front panels that opens but I ca not find the reason for why these open and not other.

Hi
there are three ways trhough which you can force a subVI to show its front panel
1. open the perticular SUB VI
click File->VI properties select window appearence catagory.
click customize button and select "Show Front Panel when called" and "close afterwads if originally closed" check boxes
save the VI
whenever you use this Sub VI every time it will pop up front panel
2. dont perform the changes suggested in option 1. place the instance of subVI in your main application and if you want that instance to popup a front panel then right click on subVI and Select "SubVI Node Setup" again select "Show Front Panel when called" and "close afterwads if originally closed" check boxes
with this option only certain instances of SUB VI will cause pop up to occur
3. this is the most flexible option. use invoke node to show front panel. in invoke node select show front panel method to popup the VI and use close front panel method to close the pop up window.

Main VI Menu event calling a subVI front panel

Hi all,
I have a subVI whose front panel is loaded upon calling by a main VI.
I call the subVI using a User-menu event.
the subvi-properties are set to allow close window and i am not handling a 'panel close' event.
The problem is....
when i run the main VI and click on the menu that loads the subVI front panel, subVI window opens, and if i click on the window-close, the main VI hangs.
i understand that the control remains with the subVI only and never returned to main VI after i close subVI panel.
but is it the only way to handle the 'panel close event' or any other way out to solve this?

Try running the VI with highlight execution turned on, and see if anything unexpected is happening, or you could post your vi and let us take a nosey

LV2011 problem with several front panels

Hello,
There is a bug in my software and I don't know it is common to every one or not. This not to be worry, I will notify you anyway. When I open only one front panel and one block diagram which having a program to communicate with a serial device. In this case, if I choose the VISA resource name, it obviously takes some time to popup the USB and after it show the port and front panel will stay in front you until you choose the device. Here, every thing is fine but when I open several front panels and working on only with serial program front panel to choose the serial device in VISA resource name. Then after some time, it took me to another front panel. I have seen this problem several times in past two months. More, even when I am decorating the front panel and front panel took some time after pushing some controls and switched another front panel.
Is this bug? Or I common for every one.
Using labVIEW 2011.

I am certainly using labVIEW from two months. So, I did not use MAX in my past time. I only used one time to check my USB 6008 device but this is off topic here. I will tell you down here.
Suppose, If I open multiple VI's and I am only working with one VI that can communicate with my SERIAL device and the rest of the VI's(Block diagram and front panel) are rested. This case, if I click the drop downlist of "VISA resource name" of SERIAL VI, then it took some time(200ms or 100 ms, just it is a guess) to populate and it is switched to another front panel which were opened and rested before. Again, I need to come to my serial front panel again to select the COM port. This is one case.
If don't have any other VI's not opened than this serial Vi. Then it stays on the same front panel.
Is this bug came with labVIEW or is it common?

How to make non-visible Control on Front Panel Appear at Design Time?

I have some Controls on the Front Panel whose visibility is changed (turned on or off) at Run Time. The problem is that if I stop the Run time, the Visibility of the Control remains in the runtime state in Design mode. So I may not be able to see or find the Control to make changes in Deisgn mode.
How can I make all Controls on the Front Panel visible, or find and make visible a Control on the Front Panel whose Visibility has been made False?
THANKS.

This is documented in the LabVIEW Help.
Displaying Hidden Front Panel Objects
Complete the following steps to display a hidden front panel control or indicator. You also can hide front panel controls and indicators.
Find the block diagram terminal for the object. If you have several terminals with the same data type, right-click the terminals and select Visible Items»Label from the shortcut menu. Find the object with the label that matches the hidden front panel object.
Right-click the terminal and select Show Control from the shortcut menu if the object is a control or Show Indicator if the object is an indicator.
You also can use the Visible property to display controls and indicators programmatically.
You also can display all hidden front panel controls and indicators.

HAVE SOUND- FRONT PANEL DOESN'T WO

hmmm, okay. Last night I installed the "Beta" driver and the EAX driver. I now have sound but my front panel doesn;t work. For some reason XP doesn't see the panels devices properly and lists all of them on the panel board as UNKNOWN devices. Is there some other driver set I need to install the front panel?

Hello tonitpp:
Unfortunately, the "Run VI" method only executes the vi and it will not open the front panel.
If you want to open the front panel, use the "Open FP" method, which is also located on the same class.
I hope this helps.

Labview front panel

dear sir,
sir i did a program for serial communication in labview to communicate with the embedded system and it is working now...
and my question???????
i need to display message from embedded system in one window of the front panel and i need to display parameter (baud rate, start bit, stop bit,etc...)in another front panel ... and this parameter front panel window should open only when i click button in the message front panel window when i require to change parameter..... can you explain how with some example

Hi steps,
Also you can try going through this link. Download the attachments(Main and sub vi) from the post and understand how to activate multiple front panels. You can do it by creating seperate vis with the required parameters and calling them as SubVIs. Also check how the values are passed between these vis through the connector pane terminals.
