How can I reference the properties of a control in a cluster in an array of clusters?

Hello

I am a newbie of Labview, so any advice is welcome on any code posted here.

I have one "tick" test VI where the operator is required to boxes that are then "signed". Once all the boxes are signed correctly, the operator indicates that they are finished to enter data and VI requires that a "representative" ticks boxes same as the operator, even once be "signed." I created a "list item" control that contains a set of a string for the description of the check list, a Boolean control object and string for the operator 'tick' and 'signature' and a Boolean control and chain for the Authoriser "tick" and signature. This control is then initialized in a table to create however many controls are required (currently 10), make a table of the clusters. See the jpg for the front panel to clarify this point.

In the cluster of list control item I want to have the 'case' Authoriser and 'signature' stay disabled and grayed out until such time as the Authoriser is validated (currently scan barcodes), how I want to activate these boxes for the entry clearance officer. I can not reference the two controls in the cluster of element control list in order to be able to change their property to disabled. I'm not implicitly reference the control. I seem to be able to access the array (i.e. a list item control) in reference, but not the controls element in this cluster of list item, this code is shown in "cluster in an array.jpg Reference.

I turn round in circles for some time now, so any help would be appreciated.

There are two ways to get a reference to an element in a cluster, in a table. The first way to begin with a reference to the whole table and deconstruct it. It's a pain. The easiest is to right-click on the item in the cluster, and then in the submenu to create reference. LV will switch to the block diagram, and you will notice that the cursor will hold a reference to the thing you clicked on. The third way to follow ("... no one expects the Spanish Inquisition... ") is in the create submenu, select the property node, then select the property you want.

  • How can I change the properties of the image to a picture fill?

    I have several images that are inserted in a gallery using the "fill" method However, when I click on the image to select this option to change the properties of the image, I can not select the image. I get the solid red border around the box, but when I double click in the hope of seeing the red dotted lines or tan border border indicating that I have selected the image, nothing happens. When I right click on the solid red border, it only allows me to change the properties of the image because I did not really choose the image, only the holder of the box.

    Any help on how to change the properties of the image to a picture fill?

    Thank you!

    It is not possible to apply settings to an image set as a background fill, the image is applied using CSS.

  • How can I change the properties of Xmath block?

    You can use the SBA (SystemBuild Access, see Chapter 7 of the guide SystemBuild) command of routine modifyblock to change any SystemBuild

    Block property. All the created blocks have a block id that must be specified in the modifyblock command.

    For example:

    modifyblock 2, {name = "myblock", color = 2, size = [100 100]}

    or to create a gain block

    createblock 'gain', {win = 2.5, name = "accelConstant"}

    to retrieve the id of the block of a created block, pass a variable set to zero, createblock will set the variable to the id of the created block

    MyID = 0

    createblock 'dead zone', {id = myid}

    modifyblock myid, {color = 1, input = 2}

    You can also get properties for a block by using the queryblock command.

    [t = c = color, location, t = blocktype threshold] = queryblock (myid)

    See Chapter 7 of the Guide SystemBuild users for more details and orders

  • How can I display the properties in the standard view of the property inspector?

    Hello

    right now, I'm looking in the development of custom Flex components and skins.

    I've heard that the public and property fields are displayed automatically in the property inspector in Flash Builder.

    However, I can't get them to appear in the display of the categories.

    Property in Kategorieansicht.png

    What should I do to display in Classic view?

    For each component of standard candle, there are different properties displayed in the standard display,

    so there must be a place where it is defined?

    Kein Property in Standardansicht.png

    And, so far I did not completely display style properties in Flash Builder, in standard or in category view.

    Can you give me any advice on these topics?

  • How can I change the data format of the digital display of the digital meter?

    I created a screen that uses digital counters to display data.  Each meter has its visible digital display so that the user can see the level accurately.  I have changed the format of the data from the meter to 2 digits of precision and want to display to have the same format, but there seems to be no way to do it.  The digital display is locked to 6 significant figures, which will be confusing for my users.  I know that this was possible in previous versions of LabVIEW, but was somehow lost to 8.6.1 and 2009.

    I am aware that I could do some "work-arounds" with channels or replacing the digital screens with digital indicators, but it is not acceptable.  How can I change the properties of digital signage?

    Hi AEI_JR,

    on the Properties dialog box, when you set the display format of the counter, you will find a switch to choose between 'Digital' (the default) and "digital display"...

  • My DVD - RW Dirve is not reading, and I can't change the properties.

    As I said above, I can't open my DVD - RW disc drive properties. I have Windows 7 64-bit, and I get the message: {Please insert A writable in disc drive (E :)} I accidentally encrypted disk when I encrypted my HDDs.)}

    My concerns

    Is there anyway to remove the encryption?
    Is there anyway that I can wipe the data DVD-R?
    How can I change the properties for the DVD-R?

    Hello

    ·         How do you encrypt the drive?

    You can burn files to a DVD-R more than once (each operation is called in a session), but you can't delete files from the disc. Each engraving is permanent.

    So unfortunately, there is not a way to clean up the data. You may need to use a new disc.

  • How can I remove the underline of the text added to the track changes

    We have a lot of content which includes underscores and when we use the added track text edit function text is green and underlined. How can I change the properties of the text added to be not underlined?

    From FM11, you can specify a custom color to use for the track changes, but styles (underline, strikethrough) are still wired.

    Even if you try to make changes to the text edit rack conditions in a MIF file, they will be crushed as the MIF is interpreted then opened by FM.

    In addition to editing the registry, how can I change the URL of a comment server which I use for exams?

    Earlier, I initiated a shared review but used only the host name of the server, not the fully qualified name (FQN) which includes the full domain name. Now, when I reuse this server for other comments that I initiate, I'm stuck with the unqualified name. People outside of my subnet cannot post comments on the server because the simple host name is not known on their subnet.

    How can I change the properties of this server so clients use the FQN?

    Jerry

    Yes, you can change the server name in the registry. After change, all the comments that you initiate with this profile will point to the new server location.
