Ability to create a 'substitution VI' programmatically for a LVOOP class?

I'm now quite a bit further with my class LV generator VI I mentioned previously (see here). However, I'm stuck again: I want my VI generator to automatically create a new 'alternative VI' (i.e., overrides a method of the parent class) for the newly created class.

In VI server interface, I have not found an invoke node to create a new "VI to ignore." Is it possible to do, maybe with a VI wrapper like the one that I was provided to programmatically set the superclass of a class LVOOP?

Thanks in advance for any help!

It works more or less as you suggested, but it requires two additional steps: since the VI script that replaces the front panel control loads the original control at run time, the old class must be copied as well (and deleted again subsequently). The complete procedure (tested and functional!) is:

  1. Copy the VI to a new location.
  2. Copy the original VI class to the new location (just temporarily necessary)
  3. Add the new VI to the new class
  4. Change the input to the new class terminals using VI scripts
  5. Remove the original class to the new location of the VI

Thank you much for the help!

  • Ability to set the legacy of LVOOP class programmatically?

    I want to schedule a class generator:

    The user selects an existing class of LVOOP and the generator produced a LabVIEW that contains a new class is a class of children of the selected class previously.

    Is it possible to set the parent of a LVOOP class programmatically class?

    Attached, there is a VI (main.vi), which creates a new project and add two classes (Parent.lvclass and Child.lvclass). How can I change the VI, such that it makes the class Child.lvclass is a child of Parent.lvclass?

    Thank you very much in advance for any help!

    You use the ActiveX interface. Is there a reason for this? If you stop using the ActiveX interface and directly use the LV, LV classes have a complete set of methods/properties available.

    As long as you use the ActiveX interface, I have no solution for you. Nothing about the libraries (which inherit classes LV) has already been exported to the ActiveX interface.

  • When you create a calendar in Photos for Mac, I can't work on the use of more than one Photo per month

    I created a calendar using Photos for Mac (picture 1,5).

    However, I can't create each month using several photos. It is the first calendar, I've done since the change of iPhoto pictures. I know I used to be able to choose various options for layout, including several photos in iPhoto. I just hope that it is something simple that I forgot.

  • create an exception in avast for the nsemail.html file in the temp folder

    I was pulling out my hair trying to find if there could be anything in the temporary files that I have to keep the last few weeks. Then I came across this: "the release of Avast 10.3.2223 (we think it's this version) has resulted in questions with avasts prevention of Thunderbird.

    computers temp folder. "So now I'm completely confused. Why would I put something I need all the time in a temporary file to have remove for cleaning ccleaner?

    Matt, thanks. I read your blog post. I need to replace my HD and I've been fretting over if I have to loose important data from the temporary files. Apparently not. When I talked about ccleaner, it was in the generic sense. I avoided ccleaner because I thought it was a big hammer and some data that he brags about getting rid of I really want to continue. I know that I can choose what remains and what is happening, I'll have to give him another look. Once again thank you.

  • How can I create a plugin to search for more than one field

    There are a number of sites that have search capabilities, but they require entries in several fields.
    For example, one such site is the directory of IBM employees.
    (http://www.ibm.com/contact/employees/servlets/lookup)
    On this site - in order to achieve usable results - I have to enter the first name and last name of the employee, that I'm looking.
    I created a plugin to search for the site, but I could not divide the text into two parts and give them separate way for the form fields.

    Is there a way to do this?

    The feature to create the hardware profile has been removed in Windows Vista and was not added to Windows 7 as well however you can check the link below which could be a workaround to troubleshoot newly installed services.

    Let me soce entry details:

    1. all computers need to have at least one administrator account. It will not work without it.
    It does NOT, however, create a profile For YOU defaultAdmin. It belongs to the user or the owner to create and decide who is Admin, and who is a regular user.
    2. even an admin account will not get to install and change the settings automatically. UAC (user account control) always appears to ask for confirmation of the task by clicking on continue, or by typing the admin password.
    3 be the main user is not to be an administrator. It is up to the user/owner of the computer to be configured as such.
    That said, now my question... How do you know that you're not an admin?

  • I bought the PC Version of Fable III of this year early and installed and created an account with games for windows Live!

    I bought the PC Version of Fable III of this year early and installed and created an account with games for windows Live! About 2 months ago, I formatted my computer and reloaded windows 7! Last night I downloaded Microsoft Flight and used my existing account to play! Today, I installed Fable III and the game won't start as it says that I am not connected to the internet! This is wrong since I write here for you! Why my game will not, organize that I have connected to my account last night with problem now? Please help me?

    Yes, unfortunately GFWL's an imperfect system. Steam has similar problems. I find the best way to avoid
    problems is to play all the games that are related to a system off line.
    I have absolutely no interest in what GFWL can offer online, in any case.
    Many games have a "fix" for GFWL, which are generally easy to find through a search.
    Of course these only help facilitate offside line.

    Try Timeslips Fable 3 GFWL remover - it is well known in the modding community, particularly
    its managers mod for Bethesda games and his job is safe to use.
