Gert,
Just right-click on the control's terminal and select ->show control. You
will then be able to delete the control as usual.

How to show or hide a control in front panel

Hi All, I am revising the code from someone else, and a control in front panel seems to be hidden until you click something to make it show. I tried to use right click in front panel and it did not work by clicking something related to show or hide. Since I don't quite familiar with property nodes, this hidden setting may be related to that.
In the picture it shows the front panel and its two property nodes, could anyone advise me how to change the setting to show this control? Thank you!
Solved!

If you right-click on the the control's terminal, you will see an option to "Hide Control" or "Show Control". This is what you should use when editing the code. The property nodes set to Visible are for when the application is running.

How to convert U32 value obtained from color control of front panel to float(SGL) for use with IMAQ Draw ?.

I am trying to get user color inputs from front panel and use it in IMAQ Draw. I need to draw an oval of a certain color in a background of another color. Both these color values are user input. The problem is IMAQ Draw requires SGL color value and the color controls of front panel give U32. I have tried conversion VI's which hasn't worked. HELP !!!

Jake,
I think the color control can be wired directly to the input, but I am not positive. I don't know of any color conversions that would help.
Make sure your image is a color image. You can't draw colors on a grayscale image.
You might want to consider using overlays, which appear on top of the image but are not part of the image.

How can i use the same front panel graph in more than one events in an event structure?

i want to display the signals from my sensorDAQ in a graph.but i have more than one event in the event structure to acquire the signal and display it in the graph.the first event is to acquire the threshold signals and its displayed in the graph as a feedback.after the first event is executed, i will call the second event,where the further signals are acuired and compared with the threshold signals from the event 1.my question is how can i use the same front panel control in more than two events in the event structure?please answer me i'm stuck.

Hi,
I have attached here an example of doing the same using shift registers and local variables. Take a look. Shift register is always a better option than local variables.

How can I save an EXE front panel image to a file?

The methods to save a VI front panel image to a file don't work on executable applications. How can I save an EXE front panel image to a file? (LabVIEW 6.1)

Hi,
i wrote some vi that save FP to image and created exe and it works fine. How do you save FP to image in VI?
If you use VI server method "Get Panel Image" and use "Write JPG file" ( or BPM) it works fine.

How to find VI's connected terminals when controls are hidden on the front panel?

When working with a sub-VI which has terminals connected to hidden controls is there a straight-forward way to find the terminals on the block diagram?
I click on the terminal and an outline appears on the front panel but when I try to click on that outline I can not unhide the control.
The only way I have discovered to find the terminal of the connected control is just check each terminal on the block diagram which looks like it might be connected.
I'm using LV7.1 but also use 8.5.
Thanks,
Davey

If I understood the premise of the question it sounds like you have controls/indicators wired to the VI connector pane, but for some reason these controls/indicators are hidden. If this is a VI you wrote slap yourself. If this is a VI someone else wrote, go slap them.
One way that you can find the terminals on the block diagram by performing a search by text. The context help will show you the names of the controls/indicators. The only problem with this approach is that if the control/indicator has the caption visible rather than the label, then the context help will show the caption, not the label.
Another method is to use scripting. Not sure if it's worth the effort for just one VI, though.
Before we get all slap-happy I have to ask...
If I have a sub-VI which is set for Print on completion and the controls in/out for the icon connector are NOT supposed to show up on the final report, isn't setting those objects as hidden a viable option?
Ben
Well, of course, Ben. My comment was not meant to be taken seriously... hence the smiley happy icon. To respond to your question in a more serious matter, though, there's always exceptions to rules. That's why they're rules - they're meant to be broken. Otherwise they wouldn't be rules. It's a strange state of the universe, isn't it? Although, one could probably just place the control behind another object. That sort of hides it, doesn't it?

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.
Solved!

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.

How to move control in front panel at run time

For example in the attach file I want to pick up the pict control (with the help of mouse) and drop it anywhere in front panel. second thing I want to ask if I want to make it copy paste, means main control will b at its initial position and where the mouse moves the image moves and when I leave the mouse the image gets drops there. How to do it. Please help me.

Hi,            &

control anywhere in front panel. For example in the attach file I
want to pick up the pict control (with the help of mouse) and drop
it anywhere in front panel.
You'll need to use an event structure to respond to the mouse down, mouse
move and mouse up events. In the mouse down event of the control, set a
value in a shift register to true. In the mouse move event, when the value
is true, change the position of the control with a position property node.
In the mouse up event of the control, set the boolean in the shift register
to false.
 second thing I want to ask if I want to make it copy
paste, means main control will b at its initial position and where the
mouse moves the image moves and when I leave the mouse  the image gets
drops there. How to do it. Please help
me.            &
nbsp;           &nbsp

You can't copy paste controls during run time. It seems you want to make a
graphical application, where you can graphically drag and drop some
configuration or something like that. You should have a look at the picture
control. You can draw anything you want in this control, and catch mouse
down, move and up events in the same way. It is perhaps a bit difficult to
get to know it, but it is very powerful when you do.

How to centre an image within tab control on front panel in LabVIEW 10 (Mac Version)?

Hello,
I would like to centre an image on the front panel. The image is on a tab control that is fit to the pane. I can't seem to find a way. I'm working with LabVIEW 10 on a Mac. Any suggestions would very much be appreciated.
Thanks,

Thanks Gita_A.
I have attached the relevant part of my program. It's not to do with the size but position of the image - I would like the image to be right in the centre of the tab control.

How to lock the size of front panel so that user can't see hidden objects?

You don't care that the code itself can be changed?
For that you can lock the VI with a password

Hmmm, Thats a really good idea! a key thought for you:
Protect the user from himself! your exe should NEVER display the Front Panel of a non-running vi. That data can't be updated or renewed - it contains no information the user could possibly be interested in. Really, that's the mindset you need while refactoring the app! Some other RUNNING utility may need to display information simillar to that shown on the vi FP in question but "Dead Data" is about the worst thing you can give to a user. (I've had simillar "Face-Palm" moments - don't feel too bad)

How to pop up another VI front panel and run this in the main VI?

Hi all,
I want to create a VI, which contain several buttons: like "RUN ANALYSIS 1" and "RUN ANALYSIS 2".
When I click one of them, another front panel of VI jump out and run automatically. When I click on "Finish" button on this VI (the one jump out), this front panel close.
How to complete it?
Thanks,

Hi Osso,
The ability to click on other VIs is also controlled by the Window Appearance. If you follow Dennis' instructions above, but this time change the Window Behavior to modal. You can find more information about the different selections in the LabVIEW Help: Customize Window Appearance Dialog Box.

How can I close a remote front panel by closing only the browser window?

I control a remote front panel in a browser (from the client PC). If I don't use the 'close' - button in my program to end the remote front panel, but instead of this the 'x' of the browser window (in the right bottom corner), my program won't be close, it continues on the server. Do you know how to end a VI by closing only the browser windows?
Thanks for any help!
wolfe

I found the examples. Thanks.
But I could not find a solution yet. Now I know how to end a VI by clicking on the x of the VIwindow.
My problem is, to end a VI by clicking on the x of the BROWSER window after I loaded and controlled a remote panel VI in a browser (e.g. IE).
If you have any ideas ... I'd be happy.
Thanks for your help.

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?
Thanks in advanced!

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

How to make some part of front panel transparent?

There is a property node to make a front panel completly transparent...but is there anything that only makes some part of the vi transparent like if I define a decorative block in the vi which takes 1 quardant of front panel and I have a control to make it transparent during runtime...
And moreover the frontpanel transparent property makes the whole window transparent, is there any way to retain toolbar of window like stop, run button when front panel is transparent??

Hi,
Have a look at this VI (attached). To make it work you need to create an image mask as a .png (open paint, colour in the areas that you want to become invisible and save it as a .png). The VI diffentiates between white areas and black areas of the mask you create, the black areas will become transparent and the white areas will remain the same- this will be implemented on your front panel. I've included an example of a possible paint image in "mask2.png".
You may also want to play around with the resolution of the mask created in paint, this will effect how the program works (I advise you use a lower resolution than your display- I used 500x300)
NT: If the front panel controls disappear, go into the block diagram window and attach a false constant instead of a control. Let me know if this works
Cheers, Tom

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.
Try to take over the world!
