returning refcursors (into Visual Basic)

Hello.

I'm having some serious difficulties with making a function returning a
recordset in the form of a refcursor to Visual Basic through pgODBC (or
through pgAdminII).
I'm using postgreSQL 7.2 and pgODBC 7.1.9
I've tried with a function such as

CREATE FUNCTION "returnCourse"("bpchar") RETURNS "refcursor" AS
'declare
    _course ALIAS FOR $1;
    _refcursor refcursor;
begin
    OPEN _refcursor FOR SELECT * FROM course where code = _course;
    return _refcursor;
end;

    ' LANGUAGE 'plpgsql';

But the only thing I get is a single value recordset with the string
"<unnamed cursor 1>".
Does anybody know what I'm doing wrong?
