How to add ASCII symbol to Front Panel

Hello,
I am trying to add an ASCII character to the front panel but I cannot figure out or find out how to do it. It should be ALT key plus the decimal code I thought.
Any help would be appreciaited.
John

you can enter an "e", select the character, and change to symbol font.

  • 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.

    Hi,
    Thank you all.. I could insert the sqrt symbol in the GUI. 
    I also want to initialise one of the strings with the same symbol. So I copied the sqrt symbol and inserted that in place of "sqrt(3)"  . but it switched back to a special character. I selected that special character and selected symbol font from the font menu, then it switched back to sqrt symbol. but as soon as i clicked the mouse outside, it reverted to the old special character(may be the one corresponding to 0xD3 in Application Font). 
    How to fix this?

  • Q:How to trim a VI's front panel at runtime?

    The occupied front panel space can be obtained by calling
    "GetPanelImage" via an invoke node. The resulting cluster "bounds"
    describes the union of all front panel objects. The front panel can then
    be resized to fit these bounds. The content of the front panel can be
    repositioned by manipulating "FrontPanelWindow.Origin". This "...Origin"
    points with an _unknown_ _offset_ (which varies with the FP´s layout) to
    the upper left corner of the front panel content.
    How to exactly calculate the origin from other front panel values?
    Thanks,
    TC

    You can use a VI Server to position the front panel of your subVI. Look at the Ghost in the Machine.vi example that ships with LabView.
    To see where to position the subVI, you need to know the position of the calling VI or of something on it. You could use a property node of the Get Details button.
    1. On the front panel on Panel.vi, right-click on Get Details and select Create >> Property Node
    2. Right-click on the Property Node and select Properties >> Position >> Left.
    3. Point to the bottom edge of the property node and pull it down to add another element. That element should default to Top.
    That will give you the coordinates of the Get Details button. Now use a VI server (based on Ghost in the Machine.vi) to place the subVI front panel the desired distance
    from the Get Details button.

  • 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 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.

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

  • 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 to add a symbol to existing keyframes

    I have completed a bunch of keyframes with 2 symbol on each moving around.  Now I want to add another symbol that will be static.  That is, at the same position in each keyframe.
    How can I add the new symbol to 250 keyframes that are already set and already have 2 symbols in each?
    I can see how to do it one by one... but there must be a better way than that.  selecting a herd of keyframes and pasting in the new symbol, ends up only effecting which ever one has the play head.
    I also realize I should have put this final symbol in at the start but too late now.  So how can I insert a new symbol in 250 keyframes all at once?

    Create a new layer for this new symbol.  Place the symbol in the first frame.  Right click the last frame on that layer where you want the symbol to extend to (250?) and select Insert Frame.

  • How to add a button on a panel's title bar?

    Hi,
    How can I add a button to a panel's title bar? Buttons that
    are simply added to a panel's title bar become invisible.
    -Altu

    One way is to put your button component oustide your Panel
    tag in your MXML. The set the x/y coordinates for the button so it
    is on the Panel.
    <mx:Panel x="20" y="168" width="250" height="118"
    layout="absolute"/>
    <mx:Button x="73" y="173" label="Button"/>

  • 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.
