Auto-adjusting fill bars - always add up to 100

My goal is to create a set of graphical controls showing that as one value increases the others must decrease, and vice versa. There will be three fill bar controls, and the sum of the three values should always add up to 100 (or less).
I'm sure we've all seen GUI's impliment functions similar to this, but I can't seem to find a *good* way to do it in LabVIEW.
I'm attaching my current unappealing rube goldberg solution, but I'm hoping someone can suggest a more elegant method (and help get rid of the rat's nest of wiring only a mother could love).Efficiency would be a plus as well, though this VI will be running in the lowest priority thread of my application.
Solved!

Hi, Alex,
You can simplify your code a little bit if you will work with event structure (you can ger reference to the slider whic was changed, and then correct values for other two).

Andrey.
PS
Upd:
Sorry, just checked - in the attached example the sliders will get negative values in some cases, but this can be easily corrected. The main idea remain the same...

  • Last pass password manager and auto form filler have disappeared from my tool bar. How do I get them back or do I have to start all over again.

    I am using Windows Vista. Both LastPass and the auto form filler have disappeared from my toolbar. Is there a way to retrieve this information or do I need to start again?

    Do those extensions still show as installed in Tools > Add-ons > Extensions?
    If not then it is possible that there is a problem with the file(s) that store the extensions registry.

  • How do you reset the Work Area Bar to auto adjust?

    This is something that's been a thorn in my side for a while. Maybe I'm just being OCD about it... but I've been wondering if there is a way, once you reposition the I / O points of the Work Area Bar (WAB) you can get Pr to go back to auto adjusting it to the end of your clip.
    You can double-click it to get it to expand to the full length of the sequence, if you remember to do that... Sometimes I'm in a rush, or I have 10 sequences and I miss the fact that my WAB is not all the way to the end. I select and batch drag them all to Media Encoder and *POW*... I've forgotten to stretch the Out to end on one sequence ... and I have to re-render. A pain, yes, something I should have double checked, but at 2am these things can get missed.
    So, can you get the Work Area Bar to auto adjust again?
    If yes, it's probably something ridiculously obvious – but I'll take it!
    Thanks

    I would have an issue with auto or a default  for a number of reasons.
    Not least this one...
    I now place dummy clip ( black video)  a  distance off the end of my sequence to prevent the End of Sequence Marker displaying at the end of my edited material.  I dont want that included in an export.
    Here is another...
    As I get to lock down and I am sending previews to clients...I insert Black Video head and tail of the edit so that the preview does not start  jarringly on first frame video.  I have I and Os marked so that I can simply  export "Program at length (without black head and tail) when I  come to master.
    and...
    Often I have edit versions (TVCs) on the same time line ( sequence) and I need to adjust WAB or I/Os to export them separately.
    Automating stuff to eliminate our dumb moments doesnt help much because it just opens the chance of another dumb moment driven by expectation and forgetfulness. .
    Mental checklist is the only way IMHO.

  • Iweb auto adjust for different computer monitor settings

    Nobody has the same display settings on their monitor, so how can I get iweb to auto adjust to different computer monitor settings?

    Are you referring to screen size? If so many prefer to have their browser window set to the size they want unlike PCs in which the browsers usually always fill the screen blocking out the desktop.
    Why not set your site width to a size that can be utilized by all, desktops, laptops and mobile devices. Apple recommends 980 pixel width for that.
    There was a post about this some time ago with, if I recall correctly, some code to do that. I think Cyclosaurus posted it but am not sure.
    I know its a personal preference but when I land on a site that forces my browser to fill the screen I leave and don't go back.

  • How to auto adjust the height of my div tag?

    This is my website www.whistleandlisten.com
    The white background is a div tag and whenever I add new content within the div tag I want it to auto adjust to extend the white div tag down as the page gets longer. I have tried css and set my height to auto but that makes it disappear. Right now I have to set it to a certain amount of pixels which gets annoying and sometimes I forget to after adding lots of content. PLEASE HELP.

    To have an extensible height element, you should not apply the height property as you have done starting at line 9 of songcss.css
    #whitediv
      position: absolute;
      left: 50%;
      margin-left: -490px;

  • New iMac brightness level keeps changing (auto adjust NOT checked)

    Just got a new 27 inch iMac and keep on having to change the brightness level back to the brightness I prefer.
    I do not have auto adjust checked, I put the brightness slider up to the level I like and after a while the brightness dims to what seems like the default level as its always down to the same spot on the slider...what gives? i just want it to stay where I want it...
    Help.

    I have same problem, of autobrightness being unchecked and my brightness going from full to about 3/4 bright
    all by itself. I had that problem, then flickering of my screen also was taking place. I didn't bring my unit into Apple
    because this autobrightness thing plus flickering would not happen on command,, and I wouldn't be able to show them properly. Well , finally my left side of the screen dimmed,, and that was the go ahead to bring it in to them
    to show the left side of screen. I also told them about the flickering,, and the autobrightness, which I figured played a role into the final left side dimming. They replaced the backlight and the display LCD on warranty.
    I have had it for about 5 days. The screen is equally lit (as should be), however, I discovered that my same old
    problem of autobrightness, is slipping back to 3/4.  So most of you have autobrightness problem in a sort of different way. I set mine to "torch" because my downstairs bedroom is dim (with one overhead light), but sometimes, just plain dark,, so I want to sometimes keep it at torch,, however, it still slips back. You would
    almost think that if my surronding was dim or dark, that it would stay on torch if the autobrightness was really working properly. Go figure. I just tried SMC a short while ago,, I had tried, before my repair doing PRAM and the other one (I think VRAM).  I also will unhook my second monitor to see if that is having an impact on things.
    Do any of you in this post have a second monitor attached,, and have you tried unhooking it to see if the problem
    is resolved?

  • Auto adjust brightness ... can it be reversed?

    I cant remember if i had this problem with Snow Leopard. Not sure if this is a Lion issue or my new MBA either.
    The auto adjust brightness seems to adjust the screen brightness to low in bright light and high in low light.
    I would like it reversed as in the dark, i dont need a bright screen and in the day, i need the screen to be brighter.
    Any body noticed this same adjustment on their Lion MBA?
    If so, does any one know how to reverse it?
    Thanks

    SAP has a program to reverse depreciation but it is somewhat complex and not available on OSS.  I'm also not sure if it is limited to (or can be ported if it is) to the older depreciation program RABUCH which would limit it to those customers that currently post using RAPOST2000.
    But barring access to the program, it's not possible to reverse it.  You would have to proceed as Jagdish describes... feed the GL data that is -1 of the data that was posted.  I wouldn't do it, personally.

  • Auto Adjust Resolution?

    I've completed my web site, everything looks as I want it.  Is there a method to getting flash to auto adjust to the end users screen resolution?  ie: when the site displays on a 800x600 monitor scroll bars appear. I'd like for the site to appear on the page as whole without the scroll bars as it does on my 19 in monitor which is set to 1024x768 resolution.

  • Auto-Adjust disabled; mic volume still adjusts.

    I have the volume auto-adjust turned off on Skype. Yet the mic volume still automatically adjusts in skype. I often run two instances of Skype. On both accounts, I have the Volume Auto-Adjust option disabled. I have even gone into my computer's hardware settings, and disabled the setting that allows applications to take exclusive control of the microphones I use. Whether the mic is built-in, or USB, Skype still automatically adjusts its volume. I've tried three different microphones and it automatically adjusts all of them. I use Windows 7, 64. Skype is up to date. Any help would be appreciated.

    I have a Razer Megalodon.  I have used it for a couple years just fine with Ventrilo, Mumble, Raid Call, Teamspeak 1 & 2, others, AND Skype.  No problems, until my most recent re-install of Skype.  I had Skype uninstalled for several months because i wasn't playing the game(s) that my online friends used Skype as a Voice Client.  I recently started playing again, and reinstalled Skype (latest Installer).  Now it seems my Microphone Level in the System Sound Options panel (Open Sound Devices> Recording> Microphone Properties> Level) gets auto-managed regardless of the settings in Skype.  This is brand new behavior on my system and only happened after installing Skype.  It seems to lower the Mic Level in my system even when Skype is closed (R-Click skype in Notification Area> Quit... Then I check Task Manager for Skype in Processes and in Services> End Task/Process Tree if still running).  Every time i try to check the way it works in my other voice clients and in the "Microphone Setup Wizard" in windows, the Auto-Leveling behavior is there, even when disabled/turned off in ALL other Microphone using programs including Windows.  When i Adjust Skype's Microphone Level from Max to 75%, i can watch the System's Microphone Level drop to 0.  When i move the Skype Microphone Level to 0, then move the System Microphone Level to 2 (yes two) it jumps Skype's Microphone Level to Max. Yes, i have disabled any and all "Application Control / Exclusive Mode" options in Windows and all my Voice Clients including Skype.  With a little digging, anyone reding this can find that there are settings on the Headset as well... again, i have been using this headset for years without issue, i know how to set it up.  As you can imagine, it makes my voice either too soft/muffled to hear, or overpowering with reverb/echo/feedback.  As mentioned before, this is NEW behavior since the latest re-install of Skype, and it is affecting my entire system and other Voice Clients now, wheather Skype is running or not.  I hope this behavior is not intended by design.  I understand the need for Auto-Leveling for those who can't be arsed to learn how their PC works beyond the "Push the Power Button Crowd," however to force those who know how to use a PC (built mine from scratch) and manage their settings properly to use this Auto-Leveling by making it "Always On" is no less than insulting.  Please, Please!, tell me this is an accidental side effect and not another intentional "Dumbing Down" tactic by MS.

  • Auto adjust in PV 2012 results in highlight clipping

    Is there any control over the Auto adjust process in PV 2012? I'm using ACR 7.4. The Auto adjustment on the Basic panel seems too hot - by perhaps 1/2 to 2/3 f-stop (net effect on the histogram) and it usually results in a significant amount of highlight clipping. Auto adjust using PV 2010 seems more reasonable.
    For example, using the same image, here's a comparison of the Auto settings:
    PV 2012: Exposure +1.15, Contrast -9, Highlights 0, Shadows 0, Whites +41, Blacks -45
    It results in some highlight clipping.
    PV 2010: Exposure +1.10, Recovery 0, Fill 0, Black +10, Brightness 0, Contrast +35
    Thanks in advance!

    Thanks Frank. And I concur with Robert Shomler: auto-toned settings may not be usable "out of the box", but it can sometimes help to see what auto-toner would do with the various settings, especially whites, but also contrast and highlight/shadows (and blacks).
    Sometimes I get stuck in a rut, and hit auto-tone, and go oh-yeah, I'm banging my head against a wall because I need more whites and less exposure, etc... (at which point I usually undo the auto-tone and continue manual toning, but more enlightened...),

  • Auto-adjust Sequence-settings to Footage?

    Hi People,
    Just a question:
    I teach students how to work with Adobe Premiere Elements. In that way I expierenced a  nice little auto-message. If a user uses a projectsetting that does not correspond to the footage that he/she imports, APE9 give a nice little warning. Followed up with the question to auto-adjust the project settings to the settings of the film. Not only does it work very well, but projects that had a red bar ontop of the timeline now seem to have less rendering issues, thus, the system works a lot faster.
    Now:
    I understand that when filming with a professional camera and editing with Premiere Pro, most users know what footage corresponds best with the sequence settings. But sometimes (...and maybe it's just me who expierences this), I get footage from strangers. Not exactly knowing what the settings are. Even if I know that the user shot the film using a Sony XDCam format, there a lots of options to choose from.
    What would you guys say, if there was an OPTION (so, not auto-adjust), to have a standard sequence, then put any footage in it, and then click on the option (rightclickmenu -> Auto adjust Sequence to Footage).
    I'd love it, but hey, maybe there already is a better way, in which case: I'd love to hear from you!

    ...maybe there already is a better way, in which case: I'd love to hear from you!
    There is. Drag a clip to the New Item button at the bottom of the Project panel (that's the button that looks like a dog-eared sheet of paper). This will create a sequence matching the clip's parameters, and place the clip into it.
    You can also right-click a clip and select New Sequence From Clip--that's in CS5.5 only, though.

  • Stop Input Auto-adjust

    I am using a Plantronics USB 645 headset and using it in Skype and recording calls. The recordings of my voice are quiet, so I have tried turning up the input levels in the Sound preference pane, but after turning it up it always auto-adjusts back down. Is there a way to stop this behavior?

    You can try locking the settings: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00850175&tmp_task=useCategory&cc=us&dlc=en&lc=e...

  • Skype Auto adjusts the mic even with the option un...

    Everytime I start a game and I'm on Skype with my girlfriend, my mic blows her ears out. 
    This isn't even just starting up a game for the first time, if I'm playing a game like Heroes of the Storm, every time we start a new game, the mic will auto adjust itself to the loudest possible setting.
    I have unchecked the mic's auto adjust propery and it still does it.
    I have gone into windows and unchecked the box to allow applications to take control of my mic.
    I have gone into regedit and copy-pasted a solution that was supposed to stop this from happening as well.
    This bug is incredibly annoying and I will stop using Skype if it continues. I don't want a program that takes over my mic because it knows better than me what volume it needs to be at.
    Anyone have any clue what the heck is going on and how to fix it?

    Hi,
    I take it you mean Microphone Enabled is Ticked in the video Menu ?
    And that the Mic in System Preferences > Sound > Input matches the one in iChat Preferences (Video Section) and that the bar moves in both places ?
    In the iChat Preferences > Video section change the Bandwidth Limit to read 500kbps as a starting point.
    iChat 5 "sees" your Internet Speed differently from iChat 4 and earlier and there may be greater speed differences between your Buddies now.
    Open the Connection Doctor during a Chat and compare the Bit Rates an Frame rates.
    Try both ends on 500 kbps.
    Then when the Bit rates look settled adjust one end at a time upwards, allowing the Connection Doctor to settle again. (The slowness of change is the iChat Buffering taking effect).

  • What is the "Auto adjust White Clip" slider for?

    The Aperture manual says:
    Auto adjust White Clip slider: Use the “Auto adjust White Clip” slider and value slider to add tolerance to Auto Levels adjustments when evaluating colors beyond white.
    But I don't know what they mean with "add tolerance". What is it intended to do?

    "Auto Levels" analyses your Image and applies a Levels adjustment based on a preset algorithm (similar to "Auto-enhance" in iPhoto, for example).  The Auto adjust White Clip slider allows you to set what percentage of pixels will be set to full-luminance.  (Hover your cursor over the slider for a ToolTip.)
    This is very easy to see in practice.  Select an Image with no adjustments applied, and duplicate it.  Then with the Auto adjust White Clip slider set to the left, click "Auto" in the Levels Brick.  Select the other Image, change the slider all the way to the right, and "Auto-Levels" that Image.  Compare the two.  Be sure to compare the histograms in the Levels Bricks: this shows you mathematically what the difference is.
