String is already a nullable type. 'null' (VB Nothing) is an acceptable null value. What it (the type, not the value) doesn't give you is cascading null semantics. For that (and many other more important reasons), I wrote a compiler for a subset of C#, which added more SQL-like null semantics to the string reference type. -- Barry -- http://barrkel.blogspot.com/ =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
