SubVIs cannot reference the Parent controls

Is there anyway that a Subvi can reference controls on the façade of a relative of VI? Without this ability, it is difficult to reduce the complexity of a VI using subVIs, when a front panel control is involved. Variable property nodes do not seem to be the ability to reference a control in a VI parent. Is it possible to fix this?

There are two ways to do this:

1. use the connector pane to indicate the reference to control of the Subvi.

2. open a VI reference to parent VI or get the reference through the connector pane. Use the [VI:Controls] property node to get references to all of the controls. You must use a loop to get good verification of the label control. As far as I know, the sequence is in the tab order in order to be able to use an index.

    Thanks for posting your query in Microsoft Community.

    According to your description, I see that you forgot your administrator password and you cannot change the parental control settings.

  • The user account cannot access the internet once parental used contract, even after you turn off the parental control

    I created a user account for my child. I am able to access the internet through firefox. Then I set the parental controls and can NOT access the internet more. I turn off parental controls for this user account. I still can't access the internet from this account.

    Parental control is a part of the operating system Windows and not Firefox. You can get help here: http://support.microsoft.com/ask-community/windows/

  • Unable to connect to the parental control with existing Microsoft Account

    I can't connect to Windows Live Family Safety with my existing Microsoft Account.

    I enter the e-mail address and password and click the Sign In button, and then get an error message saying "the e-mail address or the password is incorrect."

    The e-mail and password are correct, then why can't connect? I used to be able to connect to OK.

    1. This happens on two different Windows 7 laptops. I rebooted, cleared history, etc., and this did not help.
    2. I checked the e-mail address and the password several times (case is correct, that shift caps lock is not on, etc.).
    3. My address e-mail/Microsoft account is not an address Outlook.com, Live.com or Hotmail.com - it's my own domain, something like<*** email="" address="" is="" removed="" for="" privacy="" ***="">
    4. The Microsoft Account works for all other applications and web sites on my computer Windows 7 mobile, phone Nokia Lumia 920, Lenovo ThinkPad 2 compressed (Win8).
    5. This Microsoft Account <*** email="" address="" is="" removed="" for="" privacy="" ***="">works very well for Office 365 Home Premium.

    Thank you

    And the solution is...

    Disable the verification of two steps in the security settings for information on live.com.

    The parental control client cannot authenticate because he cannot ask the authenticator application code. Can't Movie Maker or one of the other applications of Windows Essentials .

    Awareness in two steps of authentication must be added to the Windows Essentials applications.

  • Why should I Windows 8 for the 30 minute increments in the parental control?

    As a developer of software using languages and platforms of Microsoft, I understand how planning works in an application. Why should I upgrade to Windows 8 to get the opportunity to restrict access timed to a PC safe family 30 minutes increments? This is no logic, except if it is half cooked to inform users to upgrade. This is a feature I've wanted since we began using the parental control and I can only assume the developers actually do not use the product, they have created because it really shouldn't been missed for this long. It should also be a simple change in the code to check every 30 minutes instead of 60. Maybe the team of parental controls overlap or had their budget reduced to the point that they cannot make such a simple plus change. I understand, I am in the software. I know it's less than constructive but it's annoying to know different. It's annoying to 'upgrade' to 2012 Essentials see virtually no difference in the features. Your users are not YOU!

  • Error message when you use the parental controls in Win7: "Unable to change parental controls."

    (1) I try to use the supplied with Windows 7 parent controls. However, every time I make a change to a parental control, I get an error message that says: "cannot change parental controls. If the problem persists, contact your system administrator. »

    Often, once I have clear error message boxes, the changes I made are displayed as changed. Sometimes, however, they are not applied, making these useless parental controls.

    (2) I also have problems establishing parental control measures for one of my children. Whenever I try to open the parental controls for a user account, I get the same message, as described above, then the display returns to my administrator account and does not allow me to add parental controls or change them.

    (3) when he signed then, a message in the lower right corner indicates that it uses a 'temporary' account and that any changes he made will be saved. What is a temporary account, how it is created, and how it can be changed to a normal account?

    Hi Papa_Danno,

    Thank you for keeping us posted.

    If windows was pre installed on the computer, then you must contact the Original equipment manufacturer (OEM) for the same. If the Windows 7 installation disc was purchased directly from then you can contact Microsoft directly.

    I wish that you follow the steps in the article-

    Installation and reinstallation of Windows 7

    Note: Make sure that you back up all data on the computer before you perform a Clean Installation to avoid any data loss.

    Hope this helps!

  • Siri is disabled by the Parental control on macOS Sierra admin account

    I just installed macOS Sierra today on my 13 "Mac Book Pro (early 2011). I have only one user account that is an administrator account. Siri is not enabled on my machine. When I go to the Siri system preferences screen, it says that "Siri is disabled by Parental control.

  • A new version of the parental control is available. We recommend that you update the PC of each Member of the family.

    When I connect to the Windows Live Family Safety website, it shows the opinion (in the title above) recommended that I upgrade to a newer version.  Next to this notice there is a link that says... 'install and set up parental controls'.  When I click on it to try to upgrade to a new version, need me a Windows Essentials page where it says nothing about an update.

    An attempt to update, I clicked on the symbol "Refresh" in the upper right corner of the programs parental control on each of the monitored computers, and all say they are refreshed and updated.  What is going on?  Why he continues to say that they all need new versions?

    PS. I am running Windows XP and control parental version 14.0.8118.0427.

    Hi Placebo12,

    We are happy to assist you with your concern. I understand that you wonder why the message shows up on the Family Safety website.

    The notice comes when it detects an older version of the parental controls installed on your computer. The latest version should be 15.4.3555.0308 for the 2011 version and 16.4.3505.0912 for the 2012 version. Since you're using the 14.0.8118.0427 build that is the 2009 version of the parental control, the site detects it as obsolete. Please note that the only Essentials 2009 version can be installed on Windows XP.

    If in the cases, it affects services and parental control functions, please let us know if we can help you.

    Thank you!
