Programmatically resizing Front Panel does not repaint

I am trying to extend the width of a front panel at run time when a user hits a button. The problem is
that the contents of the newly exposed front panel section are not redrawn. I have to either drag
another window over that section or minimize-maximize it to get it to repaint.
My issue is how can I get the front panel to refresh/repaint, or if that is not possible what other
ways are there to do resizing. I have tried changing the "Window Bounds" and "Panel Bounds" properties of
the VI (not at the same time) as well as using LVWUtil32 (Windows API Function Utilities (32-bit) for
LabVIEW). Each of these methods results in the same problem.
Thanks for the help!

HI Naveen,
It seems to me that you are having Problem with your Graphics Hardware, rather than labview. Generally the window should be repainted by system.
If you go to Display Properties -> Settings -> Advanced -> Troubleshooting or Graphic Acceleration - You may see the slider to full Acceleration. Under this setting the OS basically relegates most graphic duties to Graphic Hardware.
What you may want to do is to Move the slider a couple of notches back. And then try your VI's. Infact try all the settings on your Slider. See if it works at No Acceleration.
The Problem for me is I do not Have this Problem and cannot even simulate it to try a solution.
Another Solution is this -
There is a vi Property Class called "Front Panel" Which can be access
ed from Vi Server. Under this Class you will see a Property "Defer Front Panel Update" Generally this Property is used to Prevent a redraw. But if this Property is set to False, Labview immediately redraws the Panel.
What you may want to do is after resizing to let you program go through this Property Node set to False and See if this Helps.
By The way, the way you have to wire this Property is to Open a Vi Ref, Wire it to Property Node, Select Property as "Front Panel". Right Click on "Front Panel" and Click on Create-> Property -> Defer Front Panel Update. Wire the Referneces of the these Objects, with the output of "Front Panel" going to "Defer FP Update".
I hope your ver of Labview has these Properties. I am Using 6.1
I hope you can take it from there!!
Please advise How you solved the Problem. Good Luck!!

  • When the screen saver turns off my front panel does not refresh.

    when the screen saver turns off my front panel does not refresh. If I use the show desktop button sometimes I can not maximize my vi by just clicking on it from the start bar.

    I utilize both a screen saver and the show desktop feature but have never seen this problem in the past. You might play around with your screen saver settings to see if they have any affect. You might also try another computer just to make sure something larger scale isn't going on. Also, testing with other programs to make sure it isn't a general OS issue is always a good idea. Other possibilities include changing your Video Driver settings, updating your video driver, and uninstalling - reinstalling.

  • VI front panel does not pop up in teststand

    HI,
    I am new to teststand and would like to seek helps on my application.
    I have a sequence file consists of several steps. in the SETUP, I have a step to acquire input from the user on which test to run. Having said that, when i run the sequence, i do not see the checkbox test pop up automatically. How do i configure it to pop up the VI automatically.
    Also, How do we control the sequence if the user select 3 test cases? using (if) flow control in teststand?
    Please advise.

  • Resizing Extension Panel does not layout Flex controls at all, simply scales stage

    Hello,
    I'm having this issue with Extension Panels in Fireworks compiled with the Flex 4 SDK. When the panel is first opened, it has the correct dimensions and controls are laid out correctly. If I resize it at all, it scales itself instead of laying out it's controls to take advantage of the new space. This doesn't seem to occur when using Flex 3's mx:Application, only Flex 4. Any ideas?
    Before Resize:
    After Resize:
    This occurs no matter the Application container control I use - mx:Application, mx:ApplicationWindow, cs:CSXSWindowedApplication, and so on.
    My Application MXML is as follows:
    <?xml version="1.0" encoding="utf-8"?>
    <cs:CSXSWindowedApplication
      xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.adobe.com/flex/mx"
      xmlns:cs="com.adobe.csxs.core.*" xmlns:s="library://ns.adobe.com/flex/spark"
      <!-- Setting width & height are the only way I can get it to show properly when first opened. -->
      width="200" height="200" historyManagementEnabled="false" showStatusBar="false">
      <s:Button label="Click Me" />
    </cs:CSXSWindowedApplication>

    So they key is apparently to have this as a compiler flag:
    -includes=mx.managers.systemClasses.MarshallingSupport
    And in applicationComplete:
    CSInterface.instance.autoThemeColorChange = true;
    Also use CSExtension as your base application class/component.

  • Panel does not start automatically in Gnome 2.24.3

    Since Gnome 2.24.3, the Gnome Panel does not start automatically.
    I had to manualy add it to the startup group via "Sessions" in order to force it to start when login finishes.
    Does anybody has the same behavior?
    Should I report it as a bug?

    That may be true but it is a real pain since when it happens the only way to recover is to terminate all of the iTunes modules with task manager and start it manually. It also leaves the IPOD in a state that says do not disconnect. You can disconnect since nothing is really happening but there is no excuse for this not to start much faster. When you have multiple users it is a real pain. It ought to be able to either end when finished or better yet allow multiple users simultaneously updating from different libraries.
    I guess i will just have to get in the habit of treating it as a single user and start and stop it every time I need it and be suer not to let it run. Not nice because that means waiting for larger Podcast downloads instead of having there ready for me when I sign on my computer.

  • The graphic HTML signature panel does not appear in my Mac mail

    The graphic HTML signature panel does not appear in my Mac mail. I have inserted the signature after reading on the forum. But the images do not download - the rest of the text in the signature is in place - just the logo and the baseline which is a graphic file does not download.  Please help.

    Hi, are the pics at a remote location, or on your Mac?
    Have you tried drag & dropping the graphics on the signature window?

    BINGO !!!!
    Thanks so much Woodsroad. I had the exact same problem with my Dell Windows 7 64 bit with AMD Radeon 6700 Video card.
    All the video tests passed with flying colors.
    The sniffer rename trick fixed the problem.

  • Extract panel does not show in Dreamweaver CC 2014 - using Mac - Why?

    It is odd - as I used the Extract workspace, the Extract panel does not show - not even if I try opening it via Window -> Extract.
    I have updated my Dreamweaver 2014 to the most recent version.
    Can anyone help me?

  • Officejet J3680 Control Panel does not respond to buttons, just make "beep sound"

    Hi everybody, thanks for reading.
    The problem is that my (brand new) J3680 control panel does not work until I press all the buttons, yes its weird.
    Note #1: The printer works perfect when used through the computer (I am Linux user).
    Note #2: Once I have pressed all the buttons at control panel the control panel (kind of) works.
    Heres how this happens:
    I plug the power cord
    Now, the printers start and not even the Power button works, so I cant turn it off, each time I press any button it just do a “beep sound” and the LCD screen keeps the same
    The LCD shows this:
    0 Speed Dial
    <One-Touch 1>
    Now I have figured out what the LCD screen initialization means:
    0: Thats the times I have pressed the “Speed Dial” button
    Speed Dial: Thats the button I have to press to make the Control Panel works
    <One-Touch 1>: This is the next button I have to press after the “Speed Dial” has been pressed
    The printer then makes me press all the buttons (...)
    I think this is kind of some “Control Panel button calibration", because the LCD respond perfect when I press the button the printer ask
    The other problem is that I don't know how to finish this calibration or whatever this is, because I reach a point where I cant find the button it ask
    The LCD ends showing:
    1 Color Start
    <Hidden 1+Black>
    Where “1 Color Start” was the last button it asked me to press, and the <Hidden 1+Black> is the next one combination.
    Note that “Hidden 1” is not “1” not “Speed Dial 1”, I have just tried that combinations, but does not work.
    Please help I have to do this each time I turn on the printer to make the control panel work. Thanks a lot.

  • Ok, the project panel does not work anymore!!!!

    I'm using flash cs5.5 and today I opened my project to start working... just to find out that the project panel does not work. When I click the tab to expand it, flash hangs for a minute and then it works, but the panel is blank, empty. The odd thing, I saved the project as CS5 version to open it in the CS5 Flash, but CS5 it's broken too.
    I tried opening Flash (both versions) without loading any project and the tab does not work either.
    Anyone has an idea on this?
    Thanks!

    Ok, I think I get what the problem is... When I make right click over the PROJECT panel, it displays the flash player popup menu, so I guess it's made with flash/air. What I think is that my flash player is somehow screwed, so it don't displays the project panel contents and won't let me export my FLA files correctly. And it happens in both CS5 and CS5.5 versions.
    Maybe a clean reinstall of both should solve the issue... I reinstalled the CS5.5 two times, and didn't solve the problem, neither uninstalling/installing the flash player plugin for all browsers.
    kglad:
    I only see the tab, when I try to display the panel contents, FLASH hangs like for a minute, then it responds but the panel is blank... no menus, options, nothing.

  • My control panel does not have flashlight,calculator or portrait lock

    Control panel does not have flashlight,calculator or portrait lock

    There is no flashlight since the iPad has no flash with it's camera. There is no calculator icon since the native calculator app available with the iPhone version is not included with the iPad's version of iOS 7. The rotation lock depends on Settings/General/Use side switch to..., setting it to mute audio will put the lock screen button on Control Panel. Setting it to lock screen rotation will change the button in Control Panel to a Mute button.

    To get pass the passcode lockscreen, recovery mode and restoring should help: iPhone and iPod touch: Wrong passcode results in red disabled screen
    If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
    If the issue continues after updating and restoring your device, refer to this document.

  • Beware: icloud control panel DOES NOT WORK for icloud email

    Opposing evidence is welcome. Please comment.
    After dozens of hours, emails and chat sessions with both MS and Apple tech support (the latter escalated as high as it could go - "after this we have to refer you to engineering"), I was finally told by Apple Senior Advisor Ciara Ferguson that icloud control panel does not properly sync icloud mail with Outlook 365 (Outlook 2013).  After several months of working on dual systems I discovered that many (but not all) changes to folder names and filing of emails in various folders made in Outlook were not reflected on icloud and vice versa.   Ms. Ferguson has stated that icloud control panel "works better with calendar and contacts."  Obviously, this non-committal statement is grossly insufficient.  It either works or it doesn't.  It doesn't. 
    Allegedly, icloud control panel does work to sync other email (the example of an outlook.com email address was given) into apple devices.  This doesn't sound right to me either, since one can just add any POP or IMAP or Exchange account into a Mac device, so why would one need icloud control panel to interface?
    I remain stymied as to the actual purpose of icloud control panel, despite asking exactly that question of Ms. Ferguson on several occasions.  The Apple literature and its own setup screens suggest that it will sync email, contacts, calendar and notes with MS Outlook, but as to email, that is apparently untrue.

    I don't think so.  I'd like to sync photostream from two iPhones with distinct Apple IDs on our PCs and I don't see a way to do it.  It synced my wife's iPhone while she was logged in to iCloud control panel but not mine until I logged in (and disconnected her photostream PC syncing).
