Error 91 - try to use the variant of the function of data

I'm running a problem when you try to use variations in my application. I have a setup of State machine that a State creates a list of tasks (cluster of tables), and then converts it to the Variant. The variant is fed into a shift register that allows me to access the list of tasks of a different State.

The problem comes when I try to use the variant of the function Data. I right click on the task cluster to create a constant and then wire to the TYPE of the variant of the function Data. I wire the variant of cluster of task to the terminal of the VARIANT. When I run the VI, I get error 91: or the possible reasons: LabVIEW: the variant data type is not compatible with the data type of wired for the input type. ».

How can I get this error if the type that I have connected to a Terminal TYPE of the Variant Data terminal is a constant created from the exact type created a variant of?

Section of the machine of the State where I wire the cluster variant:

Section of the machine of the State where I use the data out of the cluster variant:

The constant wire to the terminal of data TYPE variant was created from the cluster that is connected to the Variant type data. I don't understand how there is a type mismatch?

Is there another State between these two?  I notice you have some tunnels 'Use default if unwired' coming out of the structure of your business.  First of all, clear on the tunnels.  Second, in cases where you do not only affect the data, the data directly from the tunnel entrance in the tunnel exit of the wire.  I recommend using the tunnels linked to make it even easier on yourself.

With the default tunnels being output, your variant coming could really be empty, so the conversion fails.

    Hello

    ROWID for individual tables can be added as events only if the rule class is set up as a Composite. For all other cases, ROWID is treated as data and they need to be formatted as a string of instances of AnyData or name-value pairs. Your script is to think that you intend to create a composite rule class while you might add ROWID individually. If please, recreate the rule as a composite class and try again. The error message you received is incorrect and has been corrected to indicate that the error is with the format data point past.

    Hope this helps,

    I insist on the pictures I want to share, go to picture messaging, select recipients and click 'next '. I can get the error message: "Organizing Elements has stopped working" and I have to close the program.

    This is obviously a bug in the program and needs fixing. Another person met it and found a solution. (I might add that the same accident happens if I try to use the function "Attachments").

  • Color image is not displayed when we call using the function DAL (LOGO)

    Hi all

    To change a picture of the legacy of the new Image in our MRL, the legacy Image is used by a lot of Faps (sections).

    (1) if we create the new article with new Images, the process becomes complex, as we need to check all the triggers and forms associated with it.so, we plan to create a field (with the same position as picture) DAL with functions of LOGO use

    EX:

    If (#process = 1)

    LOGO ("Idea", Fieldx (), Fieldy ())

    on the other

    LOGO ("LegacyImage", Fieldx (), Fieldy ())

    End

    Return("")


    Problem: The new Image is colored but when printed (called using "DAL") that is the impression that 'Black and White')

    We tried to use 'Refresh() '.


    Kindly help me with solutions,


    Thanks in advance

    Try to use the function ChangeLogo DAL instead.

    Change a logo on a section that has the set of attributes "print in color.

    This preserve the parameter "Print in color" and the logo print in color.

    keimanzero,

    Comcast of Norton Security Suite version is installed? If Yes, who and perhaps malware is most likely to cause questions you have published, in particular the failure of the restoration of the system.
    First, configure the system to boot - How to solve a problem by performing a boot in Windows Vista or in Windows 7
    NOTE: Start-up mode minimum state all the 3rd party firewalls will be disabled. Open Control Panel > Windows Firewall to make sure that the native firewall of Windows 7 is now on.

    Download and Save the update system (or CheckSUR) tool. You will need to download the specific Version of CheckSUR corresponding to the architecture of the system to Windows 7. If you do not know the architecture of the system, and then click the link that says "Click here to show or hide the instructions step by step with images" under method 2: download the update directly system preparation tool from Microsoft Download Center .
    Description of the preparation tool system update for Windows Vista for Windows Server 2008, for Windows 7 and for Windows Server 2008 R2

    Once the download is complete, close all open programs and browsers. Now, run CheckSUR with the system connected to the internet because it will download the .cab for system files. Reboot once CheckSUR is complete.

    Secondly, I suggest that you run the File Checker system while in the same clean boot state.
    To run the System File Checker tool, follow these steps:

    1. Click Start and type cmd in the field search programs and files .
    2. Right click on cmd.exe in the programs of list, and then choose 'run as administrator '.
      If you are prompted for an administrator password or a confirmation, type your password or click on continue.
    3. At the command prompt, enter the following line exactly as written including the space between thec and the/and then press ENTER:
      sfc/scannow

    When the analysis is complete, test to see if the problems facing the system have been resolved.

    If they are not, you will need to contact Norton support for the version of Norton Internet Security Comcast to get help, or just uninstall NIS, run the Norton removal tool (right click Norton_Removal_Tool.exe, choose "Run as Administrator"), reboot and then check to see if the problems are still occurring.

    To restore the operating system to an earlier point in time, follow these steps:

    1. Click Start, type system restore in the search box, and then click System Restore in the list programs. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    2. in the System Restore dialog box, click on choose another restore point and then click Next.

    3. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

    4. click on finish.

    The computer restarts and system files and settings are back to the State they were in when the restore point was created.

    Hi deacon829,

    You did changes to the computer before that happened?

    Step 1: Start the computer in safe mode and check if the problem persists, to do this, follow the steps below,

    Access the menu advanced startup options by turning on your computer and pressing the F8 key before Windows starts. In the advanced startup options select safe mode

    http://Windows.Microsoft.com/en-us/Windows-Vista/advanced-startup-options-including-safe-mode

    Step 2: If you try to install any application before this program, try to uninstall them.

    If this solves the problem, you can deduct that the demand is probably corrupted, damaged or incompatible. You can check with the manufacturer of the program for more information.
