I don't think that it's possible to initialize static variables with aggregates. I tried following through with this recommendation but I get "non-constant in-class initialization invalid for static member". I think that the aggregate initialization must be done at runtime, but for statics the resolution has to be done at compile time (just guessing). - Brandon ----------------------------------------------------------- This is an automatically generated e-mail.
