time display

Hi, I write because I can not find how to do this anywhere!

I try to display the current system time and I managed to show. However, if possible, I want that it displays the live time of the system. I think the use of a timer to update every second or minute.

Is there a more easy and logical way to do it?

Hey gyubok,

to add to what RottenOgre said here is a code example to display and update the time system. There is also a TimeFormatter class in QNX but I'm not a big fan of him and seems to be off sometimes. So I created my own:

package
{
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.TimerEvent;
    import flash.text.TextFieldAutoSize;
    import flash.utils.Timer;

    import qnx.ui.text.Label;

    [SWF(width="1024", height="600", backgroundColor="#E8E8E8", frameRate="30")]
    public class TimeDisplayTest extends Sprite
    {
        private var timeLabel:Label;
        private var myTimer:Timer;
        private var currentDate:Date;

        public function TimeDisplayTest()
        {
            super();

            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;

            displayTime();
        }

        private function displayTime():void
        {
            /*
             * We set up our label, timer and date
             * Label will display our time onto the screen
             * Timer will be used to "listen" for each second's tick
             * based on the tick we call our update function
            */

            timeLabel = new Label();
            myTimer = new Timer(1000);
            currentDate = new Date();

            myTimer.start();

            timeLabel.setPosition(100,100);
            timeLabel.autoSize = TextFieldAutoSize.LEFT;
            timeLabel.text = formatTime(currentDate);

            myTimer.addEventListener(TimerEvent.TIMER, updateTime);

            addChild(timeLabel);

        }

        private function updateTime(e:TimerEvent):void
        {
            trace("tick");

            /*
             * Every second we update the time label with its new time
             * we update the currentDate with a new date every call
            */

            currentDate = new Date();

            timeLabel.text = formatTime(currentDate);
        }

        private function formatTime(curDate:Date):String
        {
            var formattedTime:String;

            var curHour:int = curDate.getHours();
            var curMins:int = curDate.getMinutes();
            var curSecs:int = curDate.getSeconds();

            /*
             * To get the ending AM or PM we do a simple test for the hour
            */

            var curEnding:String = ((curHour > 11) ? "PM" : "AM");

            /*
             * I'm not a fan of military time so I like my numbers less than 13
            */

            curHour = ((curHour > 12) ? curHour - 12 : curHour);

            /*
             * Return the formatted time including adding zeros such as "02" instead of "2"
            */

            formattedTime = formatStartingZero(curHour) + ":" + formatStartingZero(curMins) + ":" + formatStartingZero(curSecs) + " " + curEnding;

            return formattedTime;
        }

        private function formatStartingZero(num:int):String
        {
            /*
             * Function to format and return the number based on its value of being less than 10
            */

            var formattedNum:String;

            formattedNum = ((num < 10) ? "0" + num.toString() : num.toString());

            return formattedNum;

        }
    }
}

There are some comments to explain the code. If you need assistance let me know. This must be what you are looking for. Good luck!

  • The time displayed in the "Received" column is not the last time received in the headers, this is indeed the sent time.

    RE: Thunderbird email list
    I like to see the columns 'Date' and 'receipt '. I noticed that the time displayed is exactly the same in both columns, and I knew from Outlook it wasn't normal. When I checked the headers, I found that Thunderbird did not display the received time, but rather, in all cases, it is at once sent. Here is an example:
    The last "Received" line in the header is: (> > added)
    > > received: by 10.216.205.198 with SMTP id j48csp33972weo;
    > > Thu, May 22, 2014 07:25:10-0700 (PDT)

    The other relevant line is:
    > > date: Thu, May 22, 2014 14:21:21 + 0000

    Note that there is difference of 4 minutes which is not too uncommon, but 09:21 for the two columns is displayed. It is sent in good time, but not the good received on time. It should display at 09:25 in this column.

  • Time display time display QuickTime vs FCPX

    I need help to understand what I see in FCPX.

    I have video files on a map of the camera. When I import a clip that I see, for example, an hour of starting 12:39:03; 20 and an end time of 12:49:18. 23. the shows 'content created"November 11, 2015, 18:49:35. After importation, the start and end times correspond to watch the window of time code in the center of the window FCPX.

    If I open the clip in FCP beam original media file, Quicktime show it starts at 00:00 and ends at 10:09. The person that I work with has a workflow of the first draft I Watch clips in Quicktime format and take notes using QuickTime displayed timecode. When he moves to FCPX to mark and keyword sections, the times do not match.

    We talked about its evolution, its workflow, but it's something he did for years and is comfortable with it.

    Why FCPX displays something different? Can I change the time display FCPX to correspond to Quicktime? Is there maybe a setting of the camera that I missed?

    MFT displays timecode from camera. The QuickTime X player does not work. He must use the QuickTime 7 or Pro Player or another player who displays the timecode. FCP can be made to display the time of day.

    Apple Watch does not offer the possibility to keep the screen on all the time.

    The maximum period during which the screen can stay awake without constant interaction is 70 seconds. This option applies when the screen is taken to reactivate it.

    From time to time the screen greyed out for a few seconds and restore again.
    It is not serious laptop runs on battery or plugged in.

    Can someone give me an advice?

    Hello

    Theoretically, it could be just a problem of software; for example, display driver starts to do strange things in this case, that I recommend the update or reinstall the display driver to check if it could contribute

    But it could also be a hardware problem; FL-inverter
    FL inverter is a small part that controls the backlight so theoretically, it could also be the FL inverter malfunction, but that's just my guess
    This should be checked by a technician for more information.

If you want to make any changes or customize it more, this document can help you get started. I based off of decoration - free label template, so that I could completely customize the behavior of the control.

  • time display format

    Hello everyone,

    I have a time stamp indicator in a Subvi and I he pass out as part of a cluster. the display format of the timestamp is "time format system", digits 0. When I probe the Subvi output in the main vi I get a value of time with 3 digits stamp. It makes no sense at all.

    Unfortunately, I could not reproduce this behavior in a simple to fix vi.

    Maybe you've met this kind of behaviour before.

    all ideas are welcome!

    using labview 2011

    Screen format information are not in the data; It is a property of the indicator, which is not necessarily going to be the same format of you in a probe.

  • How to make the variable data record (intermittent time), with a real-time display

    I'm a complete newbie to Labview. We are currently developing a piece of hardware in the lab to automatically take the readings of the concentration of a sample, through correlations with voltage readings. I have read and worked through the getting started with Labview .pdf, but other than that my knowledge is minimal. I have a flowsheet of work who is able to do it correctly and display and write the data in real time. However, I want to be able to write to a file only every 10 minutes or so, since experiments can run for several days and the amount of data it currently logs is unnecessary.

    Would be nice if he could write it in columns like this:

    [date time]  [voltage ave]  [levels]

    xx                     xx                        xxx

    xx                     xx                        xxx

    xx                     xx                        xxx

    .. .but only once every 10 minutes. Or at any interval of time, I put.

    I tried to connect different parallel loops, but I failed miserably. I don't know if it is a relatively simple problem for you guys to help me with.

    I have attatched file. Please note that the file variables.txt is there simply to hold the settings for the correlation of concentration, which took charge of him.

    In addition, advice or tips to improve this would be greatly appreciated.

    Hi mooray.

    I took a quick look at your code, but you should be able to do something like this:

    When you have an Express VI elapsed time set to 600 seconds (10 minutes). If every 600 seconds time out will pass a Boolean TRUE, which will allow to write the measurement file Express VI. Therefore, what iteration of the while loop, you would write some input comes in the signal input to write it into a file position.

    There are other ways to do this as well, but it's pretty simple. I hope this helps!
