problems of reference onPlayStatus Complete and scene

Recently, I went from a to an object FLVPlayer ordinary flash.media.Video to read the VOD rtsp stream.  But for the event "play.complete" at work I had to jump through hoops for days.  This code works well, but I still have questions.

Issue 1. to get the stream to throw 'complete' you need you a class CustomClient which defines onPlayStatus

VIDEO1 is already on the scene
on the main timeline
Stream = new NetStream (connection);
stream.client = new CustomClient();
VIDEO1.attachNetStream (Stream);
Stream.Play ("MP4:MyVideo.MP4");

Then set in the CustomClient.as class
public void onPlayStatus(info:Object):void {}
trace ("onPlayStatus: code:" + info.code); output NetStream.Play.Complete
}

Question:  In fact, which calls the method onPlayStatus and intersection of information: object? What is the NetStream?  If the flow already knows the name of my method, why isn't she defined in the NetStream class first?   I do not understand the purpose of the allocation stream.client

Issue 2  The CustomClient class has no access to the maintimeline.

On the maintimeline, I define a variable and a function to manage a playlist

main timeline
var nowPlaying:Number = 0;
function change_video (playListNum:Number) {}
play another video fron the playListArray
}

But when the CustomClient class call the complete method the maintimeline elements are not available
class CustomClient
public void onPlayStatus(info:Object):void {}
change_video(nowPlaying++);
}
1120: access of undefined property nowPlaying
1180: call to a method may be undefined change_video

I tried to use the scene, but the scene is also not defined in the class
trace (stage.nowPlaying);
1119: access of a nowPlaying property may be undefined, through a reference with static type flash.display:Stage

Finally, a reference to the stage of the maintimeline stayed to the CustomClient class
from the main time line
Stream.client = new CustomClient (this.stage);

class constructor
private var _main.
public void CustomClient (several) {}
_main = _stage.getChildAt (0);  first scene is mainTimeline
trace ("_main:" + _main); ' returns ' _main: [object MainTimeline] ".
}
public void onPlayStatus(info:Object):void {}
_main.change_video (_main.nowPlaying);
} / / This works!

Note that several in itself is useless.  It contains none of your business.  _stage.FirstChild is the maintimeline

Questions:  Why are they not variables and functions available for the class below them? (I'm new to OOP)
Why the scene is not accessible within a class
Why things not available on the scene?  You must use stage.firstChild to access the schedule.  I have never seen it mentioned in any of the AS3 documentation.

Thanks for your replies

You can have complicated things for yourself. With AS2, customer of the stream was implied to be 'this' and so things like onMetaData events and others, could be trapped by the features that are right there next to your other routines. If your video creation AS3 lines are in the maintimeline, you could say:

Stream.client = this;

and then the functions could also be on the maintimeline, where they would have access to everything you mentioned.

For the general problem of a class to know the maintimeline, you can either pass in a reference when you create the class, for example, if you have a customer class customized to manage your maintimeline flow, you might say:

Stream.client = new CustomClient (this);

and in the CustomClient class, you would store stores the reference passed in. Or you can most of the time you just watch roots. Like this (within the class):

var maintimeline:MovieClip = MovieClip (root);

maintimeline. DoSomeMaintimelineFunction();

  • Equium L10: Problem with the main battery and battery RTC

    Hello

    I have the Toshiba Equium L10 and it is about 14 months old and I have problems with the battery and how much time it takes after a full charge. I also have problems with the RTC battery and an ERROR 0271: check date and time settings message when I turn on the laptop.

    Regarding the battery, I can fully charge it upward in about 3 hours, but when I start to use it, apparently in the last few hours around one and a half or so and then it needs to be recharged. I can have down for about 40 minutes and then turn it off and come back later or in a day or two. How long should I expect from a fully charged battery?

    About the batttery RTC, it really becomes a pain and I only started to get the message of the ERROR 0271 start-up, in recent weeks. I can charge the battery pack and then leave for a few days, but when I turn it on, I get the message ERROR 0271 on the date and time incorrect. Surely after a full charge, the RTC battery should last longer than a few days?

    The manual says that if the RTC battery is exhausted or becomes weak, you must charge the battery of the CCF for 24 hours, in a different part of this manual indicates between 24 and 48 hours, but how can load you for long when the sections concerning the charging battery pack status after charging the battery you unplug the power adapter because leaving connected will shorten the life expectancy of the Battery Pack. So, how we can charge the battery of the CCF for 24 to 48 hours if we shouldn't leave the AC adapter plugged in once the battery is charged - which is nearly three hours. Suggestions about these problems would be appreciated.

    Besides we all know that it is easy to change the CMOS/RTC battery in your desktop base unit, but is it easy to change in a Toshiba Equium L10?

    Concerning

    Brave0

    Hi Brave0,

    The normal recommendation for the CMOS (RTC) battery is to leave the laptop connected to the power supply at least 12 hours when the main battery is fully charged. The charging circuit is going to hijack the current to the load automatically RTC battery and no current will be forwarded to your main battery.

    Recommendation do not leave the power adapter is plugged in the main battery is fully charged is really only applicable to older laptops that used no batteries Li - ion and therefore they had to be completely discharged before recharging to avoid any effect 'memory' of the battery.

    With modern Li-ion batteries, it is quite safe to leave the battery when fully charged and still power the laptop from the AC adapter. The charging circuit will pass all the battery charge if it is fully charged.

    Kind regards

  • Problems with references to cRIO as startupApp

    I am having trouble with my programs that run as starting applications on of different cRIO.

    The problem is that it takes too long to load correctly references (or load at all).

    In the attached screenshot, there are two tabs that I put the State enabled on. Page 1 is to be set as 'disabled and grayed out' and page 2 of "enabled."

    The upper part shows the reference pages directly and update tabs. This does not, as the reference table is empty.

    The lower expected the reference table to become a zero table. After a while, this happens and the while loop stops.

    The right-hand side of the screenshot is from the web server runs the program. When I press Start on my computer (but continues running on the cRIO), this is not a problem.

    For larger programs, it is very difficult to detect if the references are updated or not. Is there a method to wait until everything is ready before that code runs?

    This isn't. The problem you see is because the remote façade connects to your VI already running. Connection to the front panel remote "to not start" the VI - it's a window in a VI that is already running. For this reason, the property nodes that have been put forward that the client connects do not appear (that is, they are reset to zero by default) in the remote control Viewer.

    What is described here: functionality not supported in the visualization and control remote facades

  • Problem of sorting of tables and... Using the functionality of the case

    OK, so im do this bit of code that solves the linear equations of 3 x 3, I have most of the code actually lack just 2 small pieces for value of ascetics, garlic try to describe them as detailed as I can, no matter what type of advice or advice with any of them would be greatly appreciated

    Some details of the program:

    Equation MUST be entered in a string and not must (and probably should) be able to do some difficult fixing

    It will be limited to the +'s and-'s signs

    Problem 1.

    I don't really know how to 'sort' my equation according to their variables, example:

    User input: - 2 y + 1 * x z - 1 = 2

    I can make it look like: - 2 y + z - 1 x 1 = 2

    I want what it looks like: 1 x-2 y - 1 z = 2

    I can handle sort the equation, IF I knew the order the user will add variables, the only thing that comes to mind is turning them into a table and make a case for each (x, y, z - x, z, y - etc.) and by using some kind of process of elimination to choose the table 'longer or shorter', I really haven't got much if this because it seems like a stupid idea , but it's the only thing it comes to my mind.

    Problem 2.

    So as im fixing the spaces between characters, at least, I find a '10', I don't want one "1 0", very roughly, I managed to work around this problem by using a "find and replace String", but I'm having trouble making a "case" for her, as in, I can't understand the entry of 'right' to a string of cases. " example:

    User input: 1 x-2 y - 1 z = 12

    The result inside the box is correct and resembles a '12', but as I don't know the correct entry, obviously my default case is empty, and it passes through, so the result on the outside is a '1 2 '.

    Any link for someone who fixed a similar problem or guides would be great, I'd also like to announce that 3 weeks ago, I've not even knew what was "LabVIEW", if you can 'dumb down' a little explanation would be greatly appreciated.

    You can try to use php code Analyzer to help analyze. The joint was a quickly hacked together solution that makes several assumptions (a big one being that the entry is correct and equal to is the last thing). This isn't really a complete solution.

    Sorry I didn't have the time to comment on it. If it seems odd, I was using money orders that got lost, when I recorded it for the previous version.

  • Shutdown/sleep problems Win10 V5-573-54204G50aii and similar models

    Hello

    I have an acer aspire v5 - 573 and its got some problem with win10.

    go to sleep is not turned off in all parts of the pc.

    the operating system goes into sleep mode and the screen turns off, but the fans continue to operate and it remains hot and unresponsive.

    the only way out of this State is force it off by holding the power button.

    which obviously stop the machine completely and if the sleep state saved is lost when its powered upwards again.

    So basically the day before is unusable.

    with respect to the regular diet down, it only works if I arrested him shortly after the start (maybe an hour or two).

    If the machine is on for longer than this, a judgment will result in the same State, as described above for

    standby. pretty funny if I run the system for a few hours (until a stop working properly) and then do a restart, it restarts, but instead correctly stop...

    I have gone through several complete relocations of a different version of win10 and have installed the latest drivers acer and no other programs. the problems persist. In addition, a friend of mine who has a different configuration of this acer aspire model v5 - 573, knows very similar if not exactly the same questions.

    y at - it a fix for this? everyone knows about similar problems?

    It is a known compatibility issue with computers Intel Haswell-ULT (e.g. 4200U i5, i5 4210U i7 4500U) and the driver Windows 10 Intel Management Engine Interface 11.0.0.1146.

    The most commonly used workaround is to use the Windows 8.1 Intel Management Engine Interface 9.5.24.1790 driver.   If you're lucky, it's just a simple matter to go to the Device Manager and roll back the driver.  If you did a clean installation of Windows 10, rollback may not work, and you may need to install 9.5.24.1790.

    If you need more information or details, please search in the forum that there are hundreds of positions on the issue.

    Here is an another computer Haswell-LATER with the same problem.

    Insofar as a long term solution, I don't know.  I do not work for Acer and only Acer or Intel or Microsoft could answer that.  This Windows 8.1 MEI driver is probably the solution long term.

  • Photosmart 7520: Must the Photosmart HP 7520 TWO black ink cartridges (complete and installed) to work?

    Hello

    I read a few threads where people are struggling with the question of black ink with this printer. These threads, it seems clear that HP didn't design this system very well, and I would tend to agree. Even if someone said I could find the cartridge (bowtie) smaller at Staples, I can't find it. Even if I could find it, I don't want to have 2 kinds of ink black to store all the time. And my printer does not print black with only a new XL Black 564 installed. Is there a setting I'm missing in the menu where I can choose the XL cartridge only? The manual is not clear on this, and I think it's something that should be clearly explained.

    My question is simple, and please, one who answers, read my questions and do not provide a generic incomplete response and then put a little check mark 'Resolved' next to this problem. With 3 wires, that I read on this subject, the question NOT yet resolved or fully explained.

    The printer may be used and black printing using only the right XL cartridge or do I need to have both complete and installed black cartridges to work? And a follow-up, the left cartridge (bowtie) should stay there so he works or can I remove it and keep filling the cartridge XL to go forward with the empty to the left slot. If you work for HP and you are reading this and 100% do not know the answer... call someone at HP who has designed this printer and know please let me know.

    Thank you!

    The printer requires all cartridges having ink - they don't need to be full, but they all need to be installed and have adequate ink.  The thick black cartridge is pigmented black, mainly used for text and graphics on paper.  Thinner bowtie is the photo cartridge.  It contains dye black ink based and is designed for printing on photo paper.  Black pigmented ink is not compatible with the glossy photo media, black of the photo will be used in cases where the photo paper is selected in the driver or detected automatically.

    The Photosmart 7520 has separated from the inks and printheads, with plumbing to connect.  All inks must be present to prevent air intake in the plumbing or the print heads and keep the printheads from clogging.  See here for more information on using ink.

    Hi all

    I have a big sound even and odd / problem reading music?

    My computer using windows media player 11 and classic media windows and others to play my music in the hard lists recorded by windows media player 11 copied from my CD.

    But here's the weird problem that only started to happen now, when I play music saved on any one of the players of the computer the sound breaks sometimes but not always?

    Even if I try tp use players like windows media player 11 to play recorded video clips sound breaks toward the top, but the video image only?

    I have a newly completed with windows xp home system and service pack 3, and all memory and material necessary for a pc game of level, a new graphics card was installed and by the way the problem of noise was there before this was done?

    I don't know what is the fault? And I don't know how to find out what the required audio driver are for his computer system I?

    I tried the right click on the audio device to see if the pilot could be updated in case that's all? All he asks is a cd or a floppy disk, but I thought you could ask to search for drivers online too?

    He even now breaks the game sounds too!

    Help, please

    If you access Windows Update (start - programs - Windows Update), you can
    see if there is a newer driver. The drivers are optional updates are not so made
    automatically.
     
    Download the driver for your audio hardware manufacturer (or motherboard if
    "It's built-in sound). They are often newer than Windows Update.
     
    This explains how to disable the improvements.

  • Problems with the Precision M4400 and the graphic card Nvidia quadro 770M

    I have a problem with my Precision M4400 and Nvidia Quadro 770 M. After I installed Windows 7 64 bit, I have problems with the graphics card. I get a blue screen or graphic errors. I tried several versions of the driver. In the Nvidia forum had this problem even more. Here, they told me that only a BIOS update for the graphics card to solve the problem. Update the BIOS, but I should refer by DELL. So my question is this problem with Dell is also known, and there is already an update of the BIOS to the Quadro 770 M?

    Hi all

    I have the solution by chance. I was looking for the latest drivers GeForce for Windows 7 x 64 and I read the accompanying note: http://fr.download.nvidia.com/Windows/337.88/337.88-win8-win7-notebook-release-notes.pdf
    On page 17, you can read the following note to fix: "[GeForce FX 770 M] [portable]: blocking of the blue screen occurs after Windows starts."

    Of course, GeForce FX 770 M does not exist (and never was), and it should be Quadro FX 770 M. I can bet that nVidia has corrected this famous BSOD problem in the wrong driver because always there is nothing about any "Quadro FX 770 M - fix" in the note accompanying the latest Quadro (340.52) driver.

    You try the GeForce driver above, but to install it, you may need to download an INF file modified with the addition of the ID of Quadro FX 770 M (= "NVIDIA_DEV.065C ="NVIDIA Quadro FX 770 M"). Try without the first modified INF file because the Quadro FX 770 M is listed as a compatible chip in the version of the driver GeForce 337.88 note...

    I'll try that, even though I am completely sastified with the latest driver for Quadro (feasible) (285.62) without disable Powermizer. I did not try the latest Quadro drivers again (to be honest).

    Late me know please.

    Hello

    Thanks for posting your query on the Microsoft Community.

    According to the description, you can not connect because it is blocked to wait please and you also get error message failed to configure windows updates.

    I would be grateful if you can provide us with the following information to help us better understand the issue:

    • What is the full error message / error code that you get on your screen?

    This problem may be due to updates pending.

    I suggest you to follow the below methods and check.

    Method 1:

    I suggest you to disconnect all external devices (printers, scanner, USB (universal serial bus) drives, etc...) Except the keyboard and mouse and then start.

    If this solves the problem, then add devices one by one after the other until you discover the piece of hardware causing the issue. Then we can update driver for this particular device.

    If the problem persists, try Method 2,

    Method 2:

    I suggest you to check if you are able to connect mode safe mode by using the following commands.

    Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed.

    Follow these steps to start the computer in safe mode.

    a. boot from the DVD of Windows 8.

    b. click on repair your computer.

    c. click Troubleshooting, and then select Advanced Options.

    d. Select the prompt option.

    e. Once you open the command prompt, enter the following command and press ENTER.

    Bcdedit/set {bootmgr} displaybootmenu Yes

    One time completed, please restart your computer, then press F8 to access screen on startup, then press F4 or 4 to enter Safe Mode.

    Check if the problem persists in safe mode.

    If the problem does not persist in Mode safe mode, then perform a clean boot in order to check if any third-party application is causing the problem, as the clean boot helps eliminate software conflicts.

    How to solve problems using the clean boot in Windows: http://support.microsoft.com/kb/929135

    Note: After the boot minimum troubleshooting step, read the sections "How to reset the computer to start as usual after a clean boot troubleshooting" in the link provided to return the computer to a Normal startup mode.

    If the question did not resolve, try Method 3,

    Method 3:

    I suggest you to check if there is no update pending Windows needs to be installed.

    If so, then I suggest you to install the update and check if it helps.

    Hope this information helps. Answer the post with an up-to-date issue report to help you further.

  • Problems when views containing subqueries and the parentheses of engineering reverse

    I am running questions when using Data Modeler to reverse engineer Oracle views.  A problem occurs if the SQL view contains a subquery, one more question if the SQL view contains parentheses more than necessary.  Unwanted results include: views not valid, the main request being removed from view, leaving just the subquery, the schema name be stripped from the SQL and produces an error when testing the query and the view SQL completely deleted/ignored.

    Thanks in advance for your suggestions.

    Environment:

    Version 4.0.2.840 SQL Developer Data Modeler, build 840

    Running on Windows 7 Professional SP1

    Oracle Database 11.2.0.4, running on Oracle Exadata

    Steps to reproduce:

    1. the installer for the test:

    Create table 1A. for points of view

    CREATE TABLE test

    (col1 VARCHAR2 (10))

    Col2 NUMBER

    col3 DATE

    );

    1B. create a view with a subquery and parentheses "extra".

    VIEW to CREATE or REPLACE test1a

    AS

    (SELECT * FROM biuser2.test WHERE the col3 =)

    (SELECT MAX (test.col3) FROM biuser2.test

    )

    );

    1 create a view with a subquery, without the parentheses 'extra '.

    VIEW to CREATE or REPLACE test1b

    AS

    SELECT * FROM biuser2.test WHERE the col3 =

    (SELECT MAX (test.col3) FROM biuser2.test

    )

    ;

    1. create a view by specifying different column names, followed by parentheses 'extra '.

    VIEW to CREATE or REPLACE test2a (vcol31, vcol32, vcol33)

    AS

    (SELECT col1, col2, col3 FROM biuser2.test

    );

    1. create a view by specifying the names of different columns, without the parentheses 'extra '.

    VIEW to CREATE or REPLACE test2b (vcol31, vcol32, vcol33)

    AS

    SELECT col1, col2, col3 FROM biuser2.test

    ;

    2. run Data Modeler (stand alone, although the built-in SQL Data Modeler developer seems to work the same)

    Import of data, including the test table and all dictionary the views of trial 4.

    Any import, all 4 views have yellow triangle! icon indicating the points of view that must be analyzed, Parse old views of Style.

    3. right click and select "Parse of old views of Style" for each of the 4 views.

    Status of views are now:

    TEST1A: red triangle! icon

    TEST1B: disabled icon

    TEST2A: still has the yellow triangle! icon

    TEST2B: disabled icon

    TEST1A 4A.

    Right-click, selected Validate views has no effect.

    Examine the properties TEST1A

    Examine the query Query Builder

    Warning window will appear: parse error: could not parse the SQL query. Invalid SELECT statement. Unexpected token ') "in line 2, pos 7

    Click ok, the displayed query is:

    SELECT MAX (test.col3) OF biuser2.test

    )

    )

    Result of 'test the query.

    SQL:

    SELECT MAX (test.col3) OF biuser2.test

    )

    ^

    )

    Error at line 2, column 6:

    ORA-00933: SQL not correctly completed command.

    TEST1B 4 b.

    Examine the properties TEST1B

    Examine the query Query Builder

    displayed query is:

    SELECT

    TEST. COL1,

    TEST. COL2,

    TEST. COL3

    Of

    TEST

    WHERE

    TEST. COL3 =

    (

    SELECT

    MAX (TEST.) COL3)

    Of

    TEST

    )

    Results of 'test the query:

    SQL:

    SELECT TEST. COL1,

    TEST. COL2,

    TEST. COL3

    OF THE TEST

    ^

    WHERE TEST. COL3 = (SELECT Max (TEST.) (COL3) TEST)

    Error on line 4, column 5:

    ORA-00942: table or view does not exist

    Preferences for the Data Modeler: DDL: include the defined schema in DDL

    Note that BIUSER2 schema name was stripped from the SQL

    4 c. TEST2A

    Examine the TEST2A properties

    Look at the generator query of query

    No SQL appears

    Results of 'test the query:

    Nothing, if you use "test application" of the display properties window.

    Query executed successfully, so by clicking the green checkmark in the query designer window

    4 d. TEST2B

    Examine the properties TEST2B

    Look at the generator query of query

    displayed query is:

    SELECT

    TEST. COL1,

    TEST. COL2,

    TEST. COL3

    Of

    Error on line 4, column 5:

    ORA-00942: table or view does not exist

    Hello

    It seems that the problems with validate selected views and Parse old views of Style both TEST1A and TEST2A occur as a result of the view being defined with the SELECT initial placed in brackets.

    I logged a bug about this.

    Regarding the result of your Test request, you should be able to get this works using a connection that uses your username biuser2.

    When the Test Query window, you must set the login field at the top of this window to your biuser2 connection.

    In the case of TEST2A, it has "successfully" carried out an empty SQL string!
