Click and hold the windows bar blocks the execution of LV

Hi guys

I have a real time data acquisition application which usually is runnning full screen, and as such, I have encountered this problem before, but now we have moved to a scalable scheme and it becomes a problem...

When you click on and hold the bar title of a VI running windows, LabVIEW hold completely running the application for a second round... To be more specific: If you just click on it and move the window instantly is not a problem, but if you click and hold the left button on the title bar of the windows of the VI / .exe running, execution stops for nearly a second.

For acquisition of data in real time, it's quite a long time to strangle the reading process.

I tried this on two different brands of PC and I can reproduce at the same time.

Does anyone know what causes this behavior and, eventually, how to work around it... VI has been tested on XP and LV 8.6.1

PNG joined something 'very complex' code to illustrate the problem

Thanks in advance.

This question has been asked before, and Lynn provided the same advice that I was about to suggest - create a separate UI than the DAQ VI VI so that they function as 'independent' (I use that Word loosely) process. The DAQ VI acts as a loop of producer supplying the consumer UI VI, where the 'buffer' that is allowed to fill in between is a queue, not the buffer very limited hardware.

Sorry to break the news, but if you want to solve this problem, probably as the only solution is to have several VI for your two processes. (By the way, I am able to confirm the delay of 500-600msec when clicking on the title bar in Windows 7 Windows uses a very recent version of LabVIEW)

  • How to customize sensitivity for scrolling click-and-hold?

    Hi guys,.

    This could be a tough ask but:

    I love the scroll by click and hold the mouse wheel (or the middle button). Any ideas on how to make more sensitive while it scrolls a longer distance with less movement of the cursor?

    Note, I don't want to not simply increase the global pointer speed in mouse properties. I understand that go beyond the original click location also increases the speed of scrolling, but this means I have to move a long way.

    See you soon

    There is no setting for this function.  On the other hand, you pouvez set how it scrolls when you turn the wheel, but not click one.

    original title: "leakage" of windows

    It is a common problem with how XP displays the items on your screen. When things get a bit bogged down, you'll start to see trails of the window as you drag. Unfortunately, there is no solution, but future versions of Windows do not have this problem with a new rendering of the graphics system.

  • When I choose my quick selection tool, I click and drag the first time, and he adds (my selection). BUT if I let go of the mouse button and try to select more it goes to Negative (-) and removes all selections I made and won't allow me not one

    When I choose my quick selection tool, I click and drag the first time, and he adds (my selection). BUT if I let go the mouse button and try to select it goes to Negative (-) and removes all the selections I made and not will not let me add again. I never had this problem before, you usually need to hold down the Alt (or Option MAC) to subtract from selections. No one knows what happened or how to fix this problem, maybe a setting I accidentally hit? Thanks for your suggestions! :))

    Look at the options of quick selection - particularly the four icons on the left.

  • Press and hold the goto button

    Hello! I need help for updating an AS2 AS3 script.

    I'm simulating a feature often found on a phone where you have a button, and when you click on it something happens (in this case a stop), but when you click and hold for one second this same button another thing happens (in this case an another Stop).

    This is my original script doing exactly what I'm looking for:

    stop ();

    function startTimer ()mc, conversionTime) {
    mc
    . onEnterFrame = function() {
    if ((getTimer() / 1000) - conversionTime > 1) {
    delete this. onEnterFrame ;
    Stop
    ()3) ;
    }
    };
    }
    Button1
    . delivery = function() {
    var conversionTime : Number = getTimer() / 1000;
    startTimer
    ()this conversionTime);
    this . onRelease = function() {
    if (this. onEnterFrame != null) {
    gotoAndStop
    (2);
    }
    delete this. onEnterFrame ;
    };
    };

    Can someone help me to translate it into AS3?

    Thank you!

    Here's a way to do what you describe... I treat the goto statements, but you should be able to fill them instead traces...

    var quickClick:Boolean;
    var sto:uint;

    function changeClickStatus (): void {}
    quickClick = false;
    }

    Button1.addEventListener (MouseEvent.MOUSE_DOWN, btnPressed);

    function btnPressed(evt:MouseEvent):void {}
    quickClick = true;
    Button1.addEventListener (MouseEvent.CLICK, makeChoice);
    STO = setTimeout (changeClickStatus, 1000);   delay of 1 second
    }

    function makeChoice(evt:MouseEvent):void {}
    Button1.removeEventListener (MouseEvent.CLICK, makeChoice);
    clearTimeout() (sto);
    {if (quickClick)}
    trace ("clicked quickly");
    } else {}
    trace ("delayed click");
    }
    }

  • Click and drag the work for a few seconds then the work stoppages?

    Hi all

    See this video of drag and drop doesn't work does not in creative suite - YouTube https://youtu.be/QODs8fF84g4 that shows the problem.

    I have the same problem with Indesign, but not with the first where I can drag and drop, drag to prune, drag the elements, clips, etc.

    In photoshop I can click and drag in the layer order resort or to crop an image, etc., but after a few seconds, these functions do not work, and nothing happens at all when you click to drag. Layers are not locked, this happens with any project, no image, no matter if I open the program as an administrator or not. It is a Windows 10 computer and I'm on their beta program, but drag and drop works fine in windows/creation/other applications.

    What this may be? It worked fine a month ago.

    Help much appreciated.

    Select this option.

    The fact that you can't move the floating panels might indicate a problem with the mouse capture. When a mouse down is detected capture us the mouse and drag the user interface as you move the mouse.

    You use all third party tools that interact with the mouse?

    If you hold down the "shift" key when launching Photoshop, you can disable third-party plug-ins 3. You see the problem when you run without 3rd party plug-ins enabled?

  • macOS Sierra - press and hold the power button to enter the mode 'sleep'

    I recently updated my MacBook Air (13 inch, early 2015) model of El Capitan macOS Sierra 10.12. Before the update, hold down the power button / stop for 2-3 seconds, put the machine in standby mode. It does not properly after the update. Release the power button to switch to sleep mode works only once after each time you start the machine.

    I know he has an option to set the mode of sleep using Ctrl + button / stop and by selecting one of three options to restart, sleep and Shutdown, but who needs 3 more click click and is not fast. Also, independently of any application that is open, pressing the button walk / stop worked fine before the update, but now I need to be on the desktop even do Ctrl + Power button work.

    All patches available for it? Miss me the old way of put my Mac to sleep I do not remember if I did some tweak in my Mac, or was it a default feature...

    Greetings jainam2209,

    Thank you for using communities of Apple Support. It seems you want to put the Mac to sleep, but it does not always work.
    I would recommend read you these articles, the first article explains the ways that macOS Sierra is supposed to go to sleep.
    The second article can help if the computer won't sleep when you're trying to sleep.

  • Click and drag the question (Beginner)

I started with the click and drag, but the code did not work when I used it. I tried to use the code snippets of live code, and that no longer works. After a trace in the click function, I found that he has not been called. They are called the same, and the mouse_up function was working properly, then I don't know what the problem is. Any help would be greatly appreciated ~

    Here is the code, the important bits are in bold. I don't get any other error ~.

    To animate the object of the statue in place such that it is not named in frames before the framework where your code is trying to work with her?
