iLogic Activation error

[Anonymous]

Hi all,

When I deactivate iLogic using the API and reactivate, Inventor throw an error.

Here's the error:

Here's my code:

private void DeactivateAndActivateiLogicTest()
        {
            // Get Inventor application 
            Inventor.Application app = System.Runtime.InteropServices.Marshal.GetActiveObject("Inventor.Application") as Inventor.Application;

            // Get iLogic addin 
            Inventor.ApplicationAddIn iLogic = ItemByName(app.ApplicationAddIns, "iLogic");

            if (iLogic != null)
            {
                // Deactivate iLogic addin
                iLogic.Deactivate();

                // Activate iLogic addin
                iLogic.Activate();
            }
        }

        private Inventor.ApplicationAddIn ItemByName(Inventor.ApplicationAddIns applicationAddIns, string displayName)
        {
            foreach (Inventor.ApplicationAddIn i in applicationAddIns)
            {
                if (i.DisplayName == displayName)
                {
                    return i;
                }
            }
            return null;
        }

By the interface, it's impossible to deactivate the iLogic addin.  Maybe I'm not supposed to deactivate it but the API allows me.

Someone have an explanation?

Hi,

I copied your code to a standalone EXE. It works well. I am using Inventor 2013 + SP2.

Hi Xiaodong,

I am using Inventor 2011 64-Bit Edition (network licence) + SP2.

I installed 4 hotfix but nothing changed.  I still get the same error.

Hi Pascal,

Sorry I have not Inventor 2011 now. If you can always reproduce, I'd say that would be an issue with 2011. 

But I am curious why you need to de-activate iLogic and activate it again?

Still a problem with Inventor 2018. Has anyone solved this?

[DonStauffer99]

I ended up using iLogicVb.Automation.RulesEnabled instead.

[DonStauffer99]

RulesEnabled didn't do what I needed. Actually, neither did deactivating iLogic. Trying to reorder User Parameters but recreating parameters and deleting the existing ones screws up references to the parameter in other parameters (replaces them with constants) and puts lines in rules that reference the deleted parameter that set it to a constant. Dependents collection is consistently empty, so no help there.

Hi DonStauffer99,

If you try to reorder the parameter, you can take a look at one of my post to have a solution track: sort-user-parameters-by-code

And if you have an issue to delete a parameter, be aware that a parameter is still in use if you use it in some feature and you change an option and now the parameter is hidden (but still in use). So, you cannot delete it. You can take a look at this post: delete-user-parameter

Hope this will help you,

Pascal

Trying to restart iLogic produces an error; actually, the best method I've found still produces an error and requires that Inventor be restarted to get iLogic restarted. Here's my parameter reordering subroutine:

Still a problem in Inventor 2020.

@DonStauffer99 , Sorry for the inconvenience. The issue should be fixed in 2020.2.
