Execute External rule through a button in an iLogic Custom Made User Form

[checkcheck_master]

I think I have a simple question but can't figure it out:
How can I execute an External rule through a button in an iLogic Custom Made User Form that I already have?
See image and code.

Thanks in advance.

Hi @checkcheck_master.  If you are running this code from an iLogic rule, then I think you may be able to just add an additional line of code in your Public declarations near the top of your WinForm Class block.  Right now it doesn't recognize the 'iLogicVb' term, because it is defined elsewhere, and hasn't been introduced into this new Class yet.

Try adding this line:

Public iLogicVb As Autodesk.iLogic.Interfaces.ILowLevelSupport

...just after this line:

Public oLargerFont As System.Drawing.Font = New Font("Arial", 10)

...near the top of your WinForm Class block.  That should help it recognize that term, and use it properly later in those lines of code that are trying to run other external rules.  Let me know if that works out OK for you.

Great, thank you so much!
Recently came up why you should be happy with Inventor.
I have plenty to say but someone mentioned the Forum as a plus, I'm happy to join!

I knew I had to declare iLogicVb somewhere but this way, 'As Autodesk.iLogic.Interfaces.ILowLevelSupport', I hadn't come up with.
So my next question is, how do you get here?

[WCrihfield]

You can get one clue while within another regular iLogic rule window, and after you type in iLogicVb, hover your mouse over it and read the pop-up hint (intellisense).

It tells us that this term is defined under the default Class called "ThisRule" (which is automatically created for us in the background in every rule), and that it represents something called "ILowLevelSupport", which provided general functions.  You can then go to the regular online help page (https://help.autodesk.com/view/INVNTOR/2022/ENU) and search for that term.

Here is the link to it within the 2022 online help:

Thanks again, very clear!

Still a little less easy than expected, get this error message, see picture.

In line 76 which is 'commented'.

Hmm. Much to learn.

Also I'm struggling to exit the user form by Escape key.

Any tips in these are welcome.
