"The String to Byte Array" and its operations on-site (memory) of twins "Byte Array to string"? (or if they incur sentence of copy/memory operation?)

I can't deduct the answer to this question (topic/post title) of the help of LabVIEW on the functions.

Intuitively, it seems that the two representations of data are equal to the memory and so goes between the two should essentially be a no-op when the code is compiled... but is it? (assuming that the length of the array of strings/remains constant, can I go back repeatedly without performance?)

As a string of LabVIEW is a handful and any other type of data except tables aren't a handful; that implies to me that a string = U8-table-grip handle and so a string into an array of U8-could be a memory or inefficient operation since no conversion actually take place?

The reason I ask, is that when you work with for example TCP Read or read VISA, 'data' reading is always a string, but according to what you are doing, this string is often more efficiently processed/interpreted if converted to an array of U8 and I just want to know if (memory and CPU point of view) I can move freely between the chain and U8 array and return depending on what format is most appropriate to a point?

(Also, I'm at this stage fairly certain that the "array of strings of bytes" is cleaner AND more efficient than a type-cast to an array of U8 strin... but I could be wrong.)

I did some tests on this just now, and my conclusion is that it is completely in place. The local users group had a coding challenge when this became relevant to my solution.

  • How to intercept the radio button was selected and its data?

    Good day everyone,

    Need help on this one. This is my first post about components, specifically radio button.

    Here goes my problem, I have several groups of option button. And I want to follow the radio button on each group chose, and I'm going to get the data and pass it to a function loadVariablesNum.

    Thank you

    Any help is appreciated.

    You did not answer to my second question.  Is the button in the same timeline as the mc of content?  And now that you mention the function of the buttons, where you use this code of mine you said gives 'undefined '?

    It will be to your advantage to create a new file to resolve this problem when you have just a few radio buttons and another normal button that uses this code blue.  Once you have that working, you should be able to adapt more easily in your scenario.

    To add the good advice of TG, you don't want two of the main antivirus on the computer products
    at the same time much less running. Don't forget to use the removal of the machine tools to prevent
    problem causing leftovers when you want to uninstall/remove an antivirus/security products.

    Norton - removal tool

    Removal tools

    Here's what I use and recommend:

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leaving Standard, Web, and
    Operation of the network.

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 5.x and 4.8 x

    Avast - home - free - 5.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).

    Or use Microsoft Security Essentials - free

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->

    PCmag - Prevx - Editor's choice
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.


    I hope this helps.

  • Is there a way took care in the reorg table sys.job$ (and its indexes)?  (Oracle 9)

    I have an old database that has a table of great sys.job$ and the large index on it. (indices are just standard installed indexes nothing we did)    However the table has very little data in it now, only 22 rows.   Yet between the table and index is > 1 GB in size.

    The enforcement team asked me to reorg or shrink the table sys.job$ and explained its large size is probably due to the fact that they believe some process went wrong turned for years resulting in job creation, but his long since been cleaned.

    What motivates is to save space in the SYSTEM tablespace and possibly help some query performance.

    I know that in general its forbidden to directly manipulate the sys objects (such as truncation, insert, etc. with the exception of sys.aud$).

    Y at - it a taken way supported to reduce the size of this table.  Any document referencing.

    Yes, there is a way taken in charge.

    It's called "Recreate the database"

  • Select the last Date of multicolumn and its value adjustent cust_id

    I have a Table with 5 customer_id and 5 Dates with each belonging to its cust_id.

    I need to take the last, in my example would be CUSTID_5.  I know

    this with the GREATEST who select the CHANGE_DATE_5 (in my example), but

    How to choose the CUSTID_x? that goes along with the winning Date?

    create table test_tbl)

    number of custid_1

    date of change_date_1,

    number of custid_2

    date of change_date_2,

    number of custid_3

    date of change_date_3,

    number of custid_4

    date of change_date_4,

    number of custid_5

    date of change_date_5


    INSERT INTO test_tbl



    (111, sysdate, 222, sysdate + 1, 333, sysdate + 2, 444, sysdate + 3, 555, sysdate + 4);



    Here's one way:

    WITH unpivoted_data AS


    SELECT custid, change_date

    , EVALUATE () OVER (ORDER BY change_date DESC) AS r_num

    OF test_tbl

    UNPIVOT ((custid, change_date)

    Label ((custid_1, change_date_1) AS 1)

    , (custid_2, change_date_2) AS 2

    , (custid_3, change_date_3) AS 3

    , (custid_4, change_date_4) AS 4

    , (custid_5, change_date_5) AS 5




    SELECT custid, change_date

    Of unpivoted_data

    WHERE r_num = 1


    Having several columns for several occurrences of basically the same thing is a bad table.  This problem would be much simpler, but also more effective if each pair custid/change_date has been strored on a separate line.  In addition, you would not be limited to 5 pairs.

  • Is it safe to disable the startup of Windows Defender and its services

    I use Microsoft Security Essentials on my machine.

    In the analysis of programs that I can disable to start at the beginning - until by msconfig.exe, I found Windows Defender that can be turned off, since I'm using MSE.

    Is it safe to do?

    When you install MSE, it will automatically disable Windows Defender and event he could come at the start, it does not cause performance problem. Start by opening Windows Defender and if it shows that it is disable, then you don't need to do anything. However, if it was open, then go to settings and turn it off.

    It is better that do not disable startup for Windows Defender, in case you want to uninstall MSE for a reason, you have a protection against spyware and Windows Defender can switch on. But there is no hight impact the performance on your system.

  • Inspect the IP fragment command max and its effect on Anyconnect SSL

    Can or this command will have any negative effect on the Anyconnect of Cisco SSL customer communications?

    Do not believe that the inspection of the fragments will particularly affect AnyConnect traffic. It will be inspected for a maximum of 256 fragments before start up package for inspection. It will affect all traffic through the router, but not specifically for traffic AnyConnect.

  • Forms of the muse hosted on BC and integrated in Muse site hosted on third-party host

    I was wondering if there are plans for the forms of the Muse to be hosted on BC and ready to integrate the site of Muse is on a third-party host? If this is already possible... How?  I know of another company that allows for forms (using their program of separate web form) to be hosted through them and integrated into their web design software that can accommodate a site elsewhere... wasn't sure that Muse was able to do this also.   Thank you, I appreciate any help.

    Hi Davz,

    You can use the forms of the Muse on a third party host. But if you create a form in British Colombia and embed it in the Muse, you can not use it on a third-party host. It can be used in British Colombia only.

  • Is there a way to get the list of hosts and its groups of belonging to the vCenter folder level in 5.5 web vsphere client plugin development?


    I need to get the list of all hosts and its groups of belonging to the vcenter folder level.

    1. I created a view giving the extension point: vsphere.core.folder.monitorViews.

    2. After this step, I wrote the constraint as in my class of mediator,

    var ListConstraint:Constraint =

    QuerySpecUtil.createConstraintForRelationship ( _contextObject, 'childEntity');

    I was expecting a list of all child entities such as hosts, dc, cluster... But I have only the immediate child object which is only the Datacenter as my result.

    Is it possible to get all hosts and vCenter folder level Clusters because I need the entire list to vCenter (highest level).

    Other info:

    Object file has only two properties:

    1 childEntity - list of entities

    2 childType in-kind folder ('Virtual Machine', 'Data center'...)

    Is it possible to write a constraint specifying which list of childEntities I need using childType in.

    Example: Make Me childEntities that has a 'Host' and 'Cluster' childType but childType in doesn't have these two types.

    In addition, at this level, I could see the 'Associated objects' tab which has all the information I need, such as Clusters and Cluster tab hosts and host tab respectively.

    So, I think its possible to get this list to vCenter folder level.

    I have attached a screenshot representing the need. Kindly ignore the Conventions of naming in there since I edited the example comes with the sdk program.


    1. How can I get the host and Cluster (table of relationship) list to vCenter folder level or even at the level of the vise.global.view?

    2. once I get this list, is it possible for me to manipulate that list and send the new list to IU?

    3. is there another way to do the same thing without the help of model classes and mediator?

    Pointers to this will be very useful.

    It is not possible to obtain all hosts a folder specific vCenter from a single query Data Manager.  You need to get the list of centers of data first and then get a list of data center hosts.

    It is best to make these repeated requests to the java level and return only the list that you want to the user interface.

    You can get all the objects in the host of the system with a simple query using a constraint with targetType = 'HostSystem', but you will need to eliminate those from other vCenter servers.  See how this chassis example queries all hosts the Java later in the getHosts() method: samples/chassis-app/chassisRackVSphere-service/src/main/java/com/vmware/samples/chassisRackVSphere/ChassisRackVSphereDataAdapter.java

    Another option is to use the vSphere Web Services SDK to browse vCenter. See the vSphere management forum for help on these APIs.  See this plugin of the sample using this SDK

  • PowerCLI to change vm and its file names

    Hi all

    For 100 VMS, I need to change the inventory of vm name and its file names (vmx, vmdk, etc.) to another name.

    Could you please help to create a script that retrieves the entries to a file (existing name and new name for it) and it changes automatically.

    The easiest way is to rename the DisplayName property of the virtual machine with Set-VM.

    Then do a svMotion, which will rename all of the files for the DisplayName property.

    But, you will need space for moving VMs around, and a svMotion could take some time to complete.

    That's what I meant when I asked if you could use svMotion.
