ActiveX method with user-defined data types is grayed out!

[Anonymous]

Hi,
I am creating an ActiveX application in Visual Basic that
defines a number of functions I want to use in LabVIEW through the
ActiveX client interface.

When I create an invoke node in LV, I can display the methods and all
my functions show up in the list. But the functions that pass
user-defined types (either custom types or Enum variables) are grayed
out.

Is there anyway to make this work? Is this a limitation of LabVIEW or
did I do something wrong in VisualBasic?

Thanks,
Davide

Davide,

So everything else works except the methods that you have configured with custom/enumerated data types?  Do the methods actually pass data?  I might be easier to not use the custom types, but I know this isn't ideal.  What version of LabVIEW are you using?  Is this an embedded control?  Please repost with some additional information.

Thanks!
