Default command num is 0. Can it be replaced by a white?

NUM of default command to 0 on the front panel. Can it be replaced by a default white? I know one way to do this is to convert the number to a string. But on my face, I have an array of bunches and I prefer to keep the type of some as digital controls showing a white rather than a zero.

@chuck72352 - tst gave you some good options for display as an empty space, but the short answer is - not, there is no way to have control have no number in there by default.

The long answer (regarding why) has to do with LabVIEW data allocation and lifetime memory.  In LabVIEW, unlike many other programming languages, a value is created or initialized as soon as you place an indicator or constant control over your VI and exist only when LabVIEW is performing a garbage collection automatic operation.  In your case, as soon as you place a digital order, you initialized a digital object.  Because the digital object is initialized, it must have some value.  If she did not, you can run you code and have no number on the wire.  What it seems you are trying to achieve is a digital object that has no value, that generally does not exist in LabVIEW.  While a number double-precision has something similar to this (value NaN), most of the data types in LabVIEW are never explicitly created in the code, rather they exist as soon as the code is written.

Anyway, sorry if this has been a bit too academic, but there is a fundamental difference in LabVIEW that migration to the language many people do not realize.  To a LabVIEW data type that has a life set to check the references of data value.

  • Change the preferred default command to EXEC mode

    I'm putting a 2800 series router and prefer authentication type name of user and password rather than allowing a single password. To do this, I did:

    Router (config) # username secret privilege 15 0

    Router (config) # NomUtilisateur2 privilege 15 secret 0

    Router (config) # aaa new-model

    Router (config) # aaa authentication default local connection

    That's basically what I want--when I connect to the router through the console, he immediately asks me a username and password. The thing is - as soon as I provide the right credentials, need me the USER EXEC (default command mode) mode. Is it possible to change this so that after you enter the credentials, I'm going straight to privileged exec mode?

    Bonus question: as it is now, I have no enable password, so when I login with my references, I run 'enable' to enter exec mode privileged without him asking to specify an additional password. Is it safe to do this way - have no password enable but requiring a username and password to login?

    Hello

    We do this all the time. It works the same way on telnet

    Line vty 0 4

    Priveledge level 15

    That way when we telnet in, it takes us right to the exec.. priv mode Most people have the same enable the telnet password / console password anyway so my humble opinion, it's the same thing. If you try to be ultra safe, to do something different from your enable password and do not use this little trick... But like I said... I use it all the time.

  • Where can I get replacement CD keys for Age of Empires and the expansion packs? I have all CD and original except the keys. They were inadvertently discarded.

    I recently had to reinstall my PC.  Unfortunately, I lost the keys to my series complete collection DVD of Age of Empires III.

    I have all original packaging and discs, but miss me the installation key.  How can I get replacement keys?
    Thank you!

    You would have to buy it again.  The key is what you pay in the software, the disks are free, so to speak.  It is because this software is licensed, not sold.  The key is the proof that you are authorized to use the software.

    If you have your proof of purchase (receipt or credit card statement), you can probably go back to the store you bought originally and get free replacement. Policies very well store.

  • How to set the default boot drive? I can get to about 8 choices but only one is correct and I don't know how to do that by default.

    I hit F10 and get a choice. The default value is a flash drive with no boot of the stuff.  How do I pick up and save the right choice that the computer always looking to when it is turned on.

    Hi Herbertrosenthal,

    Welcome to the Microsoft community where you can find the answers related to windows.

    If you get multiple entries start during the connection to the Windows 7 operating system then I suggest you to refer to the following methods.

    This problem can occur because interties incorrect startup, that I suggest to read the following steps and check if it helps.

    a. log in the computer using an account with administrator rights.

    b. Click Start, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.

    c. Select the Startup tab. in the list of boot tab, select the one you want to set a default value.

    d. click on apply, OK and then click on restart and check if it helps.

    Note: If you want to change the boot drive settings then I suggest you to read the following steps:

    a. new computers often display a startup (or boot) menu. In the start menu, choose "Configuration of the BIOS," or "BIOS settings," or something similar.

    Procedures vary depending on the manufacturer of the BIOS. Usually, you must press a key (for example, F2, F12, DELETE, ESC) or a key combination whenever you turn on your computer but before Windows starts. If the Windows logo appears, you must try again by waiting until the Windows logon prompt appears, and then stop and restart your computer again.

    b. the BIOS configuration screen appears. On the BIOS Setup screen, choose the option called "Boot order" or something similar. Startup command parameters may also be listed under "Advanced settings" or something similar.

    c. Select your drive from DVD or USB drive as first boot device. (The USB flash drive can be listed under "Removable devices" or other similar term).

    d. save the setting changes, and then exit the BIOS.

    Note: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

    If you need Windows guru, do not hesitate to post your questions and we will be happy to help you.

  • After you click the command button, the user can not change form

The document has been changed since its creation and use of the extended functionality is no longer available.  Please contact the author for the original version of this document. "Is there a way to fix this?  Thank you.

    FYI, the JavaScript code for the command button is the following:

    var arrayFields = new Array (this.numFields);

    (IT) {/ / default is 'this'}

    for (var k = numFields; k; k-) {}

    for (var k = 0; k < numFields; k ++) {}

    myPage var = t [i] .spawn (page_start, true, false); together second opt to false to keep the names of files

    Get the name prefix field that Acrobat will automatically add the new fields

    var f_prefix = 'P' + (page_start) + '.' strName + '1';

    Reset the newly created fields

    this.resetForm ([f_prefix]);

    Go to the new page

    }

    Yes. If you don't have the original version, unchecked, you can open the version activated in Acrobat and select: file > save a copy

    This will create an incompatible version. Note that it will automatically open in Acrobat when you do this.
