How to create a grid with the tables and Boolean values?

As part of a larger project, I'm trying to create a Subvi, which will allow me to spend a "cursor" in a 3 x 3 matrix.

It should be 2 Boolean inputs, one for move them down in the table and the other to move them to the right. Once reached the edge of the table, the "cursor" will start back at the beginning.

I have a vague idea of a table to 2 dimensions with LED. Once 'down' has been selected, the corresponding light to (0,0), light (0.1). Goes the same for the button 'right '. When 'down' is pressed (0.2), the LED should turn off, and LED (0,0) must light up.

I'm sure it has something to do with the initialization of the tables, but I can't seem to find the right way to do it.

Any help is much appreciated. Thank you!

Your array is always empty.  Look at the detailed help for the function page replace table subset.  He says that the function has no effect if the specified index refers to a location outside the table.

What you see on the Panel is only a view and has nothing to do with what is in the table.

  • How to create a CD with the OEM of the WinXP operating system?

    Hi all

    I recently bought a Tecra A7 that has Windows XP OEM preinstaled. My question is: has Toshiba any tool to create the WinXP CD? If not, why so and how can I do this cleanly? I want my PC to do the tests and I probably have to format in the future!

    Thank you to
    Pedro

    Hi Pedro

    Yesterday, I created a backup image on my laptop because I want to test the new Vista and my Xp was preinstalled on your laptop.
    In any case, I used an application of Symantec Ghost. I used it several times and I think it s very nice and useful program to perform a backup and restore. You can create a clean bootable CD or DVD, or you can save the file to the image on the second partition

    I guess you don t have a Toshiba restore CD. Am I wrong?
    I have a very dedicated forum user and, recently, I have read in the forum that Toshiba offers an option for the creation of a clean driver & tools cd of Mr. perhaps you will find an option to create an image, but I don't know m.
    AFAIK you should find it in assistance under protect & difficulty tab.

    But if you want to save your picture using the program like ghost.

  • srvrmgr syntax: How can I create subsystem named with the name and Description of the values?

    Looking through the library, he did discuss are of syntax that allows you to include the value of name and the named value of the Description of a subsystem/Profile Configuration.  In the screenshot, the circled values were created with the server online order Manager.

    NamedSubsystems.gif

    On the other hand, pouvez create a definition of the element with a name (full name) and a Description.

    For CompDef, it works:
    create the CompDefTest1_enu component definition for the type of component AppObjMgr component fins group run mode interactive full name 'Test Comp Def Test 1' description 'Test 1 CompDef Manager object.

    For named Subsytem, it does NOT work:
    create named subsystem Test5 subsystem EAITransportDataHandlingSubsys full name 'Test 5' description 'Test 5 Description'

    Someone can tell me if there is a good for a named subsystem, syntax to include the name and Description of the values in the command line, or is the only way to create it manually in the UI?

    Hello

    I spent reviewing aid to create the order in srvrmgr, it does not give the full name and description as parameters for the creation of subsystem. However, as you noted these settings are available for creating components definition:

    srvrmgr > help to create

    Create {component group | compgrp}

    [full name: ]

    [{description | desc} ]

    create {definition component: compdef}

    for {component type | comptype}

    {Component group | compgrp}

    run in mode {batch | interactive | background}

    [full name: ]

    [{description | desc} ]

    [with [ param =[, =...]]]

    [[fixparam =[,...]]]

    create the subsystem named for

    subsystem with = [,...]

    Shelf also has an example of creation of subsystem that doesn't include no description, name and first name:

    http://docs.Oracle.com/CD/E14004_01/books/StoreFwdMsg/StoreFwdMsg_InstallConfig14.html#wp1351472

    In this case I suggest that allows you to create a ticket on My Oracle Support to confirm this srvrmgr does not support the creation of a new subsystem with the full name and description settings and request an enhancement for these settings include request in create statement for new subsystems when using srvrmgr.

    It will be useful,

  • How easy to keep compatibility with the development and staging ucm

    Hello

    The content is organized by the record. The limits of the virtual folder to 1,000 files. If the number of the item of content of the virtual folder above the limit, I have to create the folder manually. Is it automatically average to cope?

    However, the record of the Complutense University of MADRID is identified by file ID, not the name of the folder. When I create the folder on the development, there may be conflict with the AAU of the stadium. Is there a best way to manage?

    I agree that WebCenter would be an overdose just for that. If necessary, take a look at the ADF, though - it's not a product, rather a Java development framework, and the birds are singing you could use this knowledge in the future versions of the AAU.

  • How to install hp dvd with the software and drivers, which came with a recovery CD?

    G72 259WM laptop... The application and Driver Recovery DVD supplied with the recovery kit (3 DVDs) was not loaded on my laptop when the hard drive has been replaced. I want to intall it butg there install the files on DVD and windows does not load it automatically. I just want my laptop to factory as it was when I bought the system.

     

    [personal information] I could not find a way to do this, please help! Thanks in advance!

    The shop obviously does not use your recovery disks to install Windows on the new drive. I had suspected that when you said that none of the original software has been installed. Recovery Manager also would have been installed.

    I would go back to the shop, with the recovery discs in hand and ask that they make a correct installation, or do the installation yourself. Put the first disk in the CD/DVD drive, and then restart the laptop. If you get a prompt to hit any key to boot from the CD/DVD, press the space bar.
