i have an addin that creates multiple UDF's that are then managed/validated on the main form and i would like to prevent the user from amending the UDFs from within the UDF pane so that my validation is always used.
What I would like to do is to create a UDF category from within the addin and assign my UDFs to that category so that they are not shown by default.
I cannot see that this is possible, does anyone know if it is?
