I don't know the details, never having studied VB manuals, although I
once saw the source of a file that described the linkage to a C
module (pretty ugly but effective and no need for wrappers).

Do you have the time to describe this in somewhat more detail for us
lucky folks who haven't had the pleasure to learn VB?
