ellapsed time always measure zero in FlashBuilder 4

Here's what I found so far:

I declare public variables.

< fx:Script >
<! [CDATA]
import flash.utils.getTimer;
Import mx.controls.Alert;
Import mx.events.FlexEvent;
Import mx.events.ListEvent;

public var today: Date = new Date;
public var beg_tck: uint;
public var end_tck: uint;

I start my application in debug mode.

I then click on a button and load the beg_tck variable:

protected function btnGo_clickHandler(event:MouseEvent):void
{


beg_tck = Now.getTime ();
... "hit and stay off of debugging...
}

I switch to the debug screen in FlashBuilder 4 and wait about 3 seconds, and then I take with F8

I have a updateComplete who load the end_tck and displays their contents.

protected function grdSBJs_updateCompleteHandler(event:FlexEvent):void
{
end_tck = Now.getTime ();  -beg_tck
lblResponseTime.text = "response time:" + ((end_tck)) String + "beg_tck:" + String (beg_tck);
}

For some reason, beg_tck and end_tck are ALWAYS THE SAME.

Why is this happening?  Even if I braked treatment for 3 seconds, the Now.getTime () is put the exact number in beg_tck and end_tck.

Thanks in advance for any help you can provide.

Because even now, refers to the same object (the one that is created when your component is initialized). Try the new Date () .getTime ().

  • Table of index always returns zero when reading the table 3D

    I have a 9 x 2000 x 5 table table 3D diamension.  I have this table filled with data and when I try to read a data point unique on the table the function Index Array always reads zero. I place a probe on the 3D input array and when I put in the index of the probe to the same data point the probe shows the value stored in the table. I also have an indicator showing the 3D table and it displays data in all locations. For example if I try to read the location 0, 144.0 in 3D it array always return zero. Yet I know that the value of this element is 6.8616E - 5. Each item I try to retreave table gives zero.

    Anyone saw the Index room table this kind of behavior?

  • Beta Analytics: what units the "time spent" measured in?

    Hello team DPS,

    I have 2 questions:

    (1) I have searched but cannot find in what units the "time spent" measured in. I think it's in the years . Please add this to both graphics and mouse-over-discriptions.

    2) also have the folio Total time spent: 17018 units, but for the same period total for all the items of the same folio to addition the: unspecified: one is 14885 units. I understand that clean up statistics 'unspecified' will also correct these Total time spent for the folio number.

    > We will be solve this in our next realease by cleaning the "not specified".

    -This means in R30, R29 was just realeased?

    Thank you

    Gennady

    Gennady salvation,

    Thanks for the comments, the total time spent is in seconds and it would be included in the release of the phase 2 of R29 coming out in early January.  #2 in will be also fixed in the release of the phase 2 of R29.

  • GetStat-entity (Cluster) - CPU in real-time - values to zero of the recent time intervals

    Hello world:

    I have a strange behavior when querying via PowerCLI CPU statistics.  We have a handful of clusters in a data center, some with HA + DRS and some DRS only.  PowerCLI seems to report different time intervals (5 min. 20 s vs) according to which cluster is queried and for the most recent 15 minutes of data queries is always zero, although sometimes it's only been 5 minutes which are zero.  This behavior is indicated for applications on clusters and resource pools.

    Is this known behaviour?  vSphere Client shows that the data is present when searching in graphics in real time, so it's confusing why smaller or no value is present at all from the CLI.  Ideally, I would like to know the average use of MHz and percentage for all groups to 20 s averaged granularity on the last 2 minutes, but no amount of massage does seem to happen.

    example query:

    Get-Stat - Realtime-Stat "cpu.usagemhz.average" - entity (Get-ResourcePool-name 'Low') - departure (Get-Date). AddMinutes(-20)-Instance "

    As I understand it, the measures for groups and entities related to the cluster as resourcepools, are aggregated values of definition.

    Which means that the vCenter must calculate these metrics of the values collected by the ESXi hosts.

    In other words there is no interval in real time for the metric for clusters, only of the historical intervals.

  • Want a ramp of output voltage over time and measure input 2 analog USB-6008

    Hello

    I want to produce an analog voltage output signal that increases over time with a certain slope, which I'll send in a potentiostat and at the same time I want to read voltage and current (both are represented by a voltage signal) that I want to open a session and ultimately draw from each other. To do this, I have a DAQ USB-6008 system at my disposal.

    Creation of the analogue output with a linear ramp signal I was possible using a while loop and a delay time (see attachment). Important here is that I can put the slope of the linear ramp (for example, 10mV/s) and size level to make a smooth inclement. However when I want to measure an analog input signal he's going poorly.

    To reduce noise from the influences I want for example to measure 10 values for example within 0.1 second and he averaged (this gives reading should be equal or faster then the wrong caused by the slope and the linear ramp step size.) Example: a slope of 10 mV/s is set with a 10 step size. Each 0.1 s analog output signal amounts to 1 mV. Then I want to read the analog input in this 0.1 s 10 values)

    Because I use a timer to create the linear ramp and the analog input is in the same loop, the delay time also affects the analog input and I get an error every time. Separately, in different VI-programs (analog input and output) they work fine but not combined. I searched this forum to find a way to create the ramp in a different way, but because I'm not an experienced labview user I can't find another way.

    To book it now a bit more complicated I said I want to measure 2 input analog (one for the voltage of the potentiostat) signals and one for the current (also represented by a voltage signal) and they should be measured more quickly then the bad of the analog signal. I have not yet started with because I couldn't read on channel work.

    I hope someone can help me with this problem

  • How to find the time to what zero crossing point occur using zero crossing vi

    Hello 
    Im trying to find the time to the point of inflection of a Bio-Signal with the 2nd derivative, then detecet the point of zero of the derivative signal
    What I need, is to mark the point of inflection on my Bio-Signal at the point where the derivative signal crosses the zero.

    The second has two scales on the graph, one on each side.  The first has only a single scale. I do not change the name of VI, so both have the same name.

  • CVI9.0 time (NULL) returns zero

    I just upgraded to CVI9.0 on a project and I got a zero on this curtime = time (NULL);

    time_t starttime, curtime;

    CURTIME = Time (null);
    DIF = difftime (curtime, starttime);
    This caused a Fatal run time error later in my code so program suspended in the debug window.

    In debugging the curtime value was 0.

    This program has worked well in CVI8.0.1 before the upgrade.

    Sorry my mistake. Had a bug in my software. line was bypassed.

  • VCSC time always ahead on 15 minutes around

    Hello

    When NTP in starting state, time to reflect the correct time, but after synchronizing, always 15 minutes before time.

    On virtual VCS the vmtoolsd synchronize time with the host of the virtual machine. The VCS NTP system does also. If time of the host is not correctly synchronized 2 systems will fight causing the time jump and NTP for eventually abandoned causing alarm signals are triggered etc.

    There is a difficulty in X 8 to stop vmtoolsd time synchronization, simply so that the VCs will define the time, but I'll need to talk with the developers to see if something can be done before the release to help systems in the field. Configure the NTP and time correctly on the host of the virtual machine should help though.

  • Is it possible to keep the timer "always on top"?

    When you use the timer I like to keep the timer of disappearing from the screen saver, but I didn't understand how to do... If that's possible.  After the timer starts, he goes down to a few seconds and the clock face appears again.  To check the time remaining on the timer, you must click to the home screen and select new application timer... which, in few seconds again goes to the background and the face of the clock reappears, again he must open the clock app to see the remaining time.  If there is a way to keep the timer "on-top" without having to repeatedly touch the screen during execution of the timer, I have not discovered.  I would also add the timer to my eyes so I can toggle to him as well.  Of course, I can do it on my iPhone, but the Watch has not yet this ability.  Apple engineers could make sure with the timer and the timer if they see the need.  Are there others who want that ability as well?  I think so.

    Hello

    It is not currently possible to add Timer looks. However, your watch can be configured for more convenient use of the application of the timer:

    • Set your watch to return to the last app used to raise your wrist:
      • On your iPhone, in the application of the watch, go to: Watch My > General > wrist Detection - turn on.
      • On your iPhone, in the application of the watch, go to: Watch My > General > screen Wake:
        • Raise the topic on the wrist, select RESUME last activity.

    After you start a timer by opening the timer app, your watch will return to timer (for as long it remains the last app used) when you then lift your wrist.

    • Add a Timer to your dial of the watch as a complication. When you view the time on your watch:
      • Firmly press the display > drag left / right to the face of the watch you want to customize (not to slip if you want to customize the current face of the watch).
      • Press the Customize button.
      • Some watch faces offers more than one screen customization options > move left until you reach the last screen to select (if available) complications.
      • Tap a complication to customize what is shown in this place.
      • Turn the digital Crown to scroll through available there complications until you reach Timer.
      • Press the digital Crown, then press the dial to return.

    To start the timer directly from your watch dial, press the complication. Once started, the remaining time will be then showed complication on your watch until the end of the timer dial, when the application opens for you to make them disappear.

  • Windows time always changes

    Hello

    Lately, I have a problem with my vista sp2. The exact time is 29 March 2013 12:23 AM. Yet, if I stop vista for an hour or more, when I restart the PC time system strangely transformed in March 11, 12:00. I have reset on the exact time, but if I stopped it, it will change again for another time, say 2 agusts 2013 23:00, and so on.

    I if it stops and it reboot after a few minutes, the time is correct.

    Comprehensive analysis of MSE can't find anything.

    I am confused, can someone help me?

    Thank you

    Low battery can keep the date and the time of change of random dates and the times. The information you have provided your motherboard is six years old (and the battery was built before the motherboard), two scanners showed no malware, so I think it's time to replace the battery.

  • very slow laptop, formatted several times, always slow

    My laptop used to work perfectly and quickly. However, lately it has been running terribly slow. I have reset the software to factory several times - still slow. I received a new standard ISO MS, (X 17-58997), cut on a dvd, reloaded the o/s.

    It takes several days to load the o/s. Also, it took several attempts for a reason any. I had to delete all partitions, including the HP ones (sigh) stock, to get it in French - last night. However, it is still being slow extremmmmely. I removed the ram and tried different sticks - same thing. This may not be a software problem - can it? It must be hardware.

  • Hanging tool select disabled but time always snaps between sampling Points

    Hello

    In the Waveform Editor, when I Zoom in directly on the waveform, the points become visible. I have 3 Q: -.

    1. What are these points
    2. They can be changed
    3. How can I select (with the Selection tool) anywhere on the waveform?
      1. I deselected waspish and yet I am with zoom basically I can only place the time tool (TST) between the points visible, i.e. hearing snaps TST so I can not place exactly there where I want

    Thank you!

    The points show the individual samples in your digital recording.

    Jump to your last question, you cannot place the time between samples picker because samples are smaller individual representations of the original audio.  the lines between the samples are an artificial creation, making a waveform of samples.   There is an excellent video showing how digital audio works - I recommend highly a cup of coffee and a viewing: D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) - YouTube

    Spacing of samples is determined by the sample selected speed which, in turn, is controlled by the clock system (Word clock).

    As for the editing... not really.  Older versions of hearing used to allow you to enter a sample and move it upwards or downwards, but the results could be unpredictable - under Nyquist theory there is only one waveform (i.e. one correct) which corresponds to the sequence of individual samples.   Changing a single sample (or even two or three) can force the system that analyzes samples and draws the analog waveform by doing a few calculations confusing, incorrect.   If you watch the video above and "read between the lines" you can see why that would be.
