Passing a string to a C-written DLL (a "char *") is to be used from
within VB by redeclaring that argument's type 'ByVal' rather than
'ByRef' (I know, it sounds rather absurd). This means one is tempted
to specify that argument as an 'in' argument, in Ada. However, if the
C-written DLL writes into that string (albeit only *changing*, not
necessarily lengthen it), I think you can indeed have an access
violation ...

In other words : is your problem still the same when specifying string
arguments as 'in out' ?

Kind regards,
