PB Classic : using enum .Net with OLE Object

Hi,

I use a .Net dll (registered for COM interop) through OLEOBjects in Powerbuilder 12.5.1.

It works, I can use class found in this dll (with ConnectToNewObject function).

My problem is a special function that requires an argument of "enum" type. I don't know if it's possible and what is the syntax to use.
