Please, be a bit more explicit when posting such questions, you never said
you had some working  code.
That said, I suppose you are using LoadTypeLib to load a typelib and use the
System.Runtime.InteropServices.ComTypes namespace classes to inspect the
typelib info, right?
When you look at the typelib using oleview, you will see that the global
data declaration (like SomeVal as Integer) are simply exported as property
setter/getter members of the interface, so when you get the typeinfo from
the interface you should be able to get at the properties (your global
variables).
The same is valid for the enum types. If this is not the case, first inspect
the your typelib using oleview, and post your failing code to get some more
help from the crowd.
