Hi all,

At the end of this mail I put the humble piece of code that workaround the 
string encoding made by visibroker 3.3 for delphi into the Any type (see 
previous mail of this thread for more precisions).
In it, the data_record type is a sequence of Any.

It has been writen by my collegue Christophe Martin.

Cheers,

Christophe 

The piece of code :

class procedure Tdata_recordHelper.Write(const _Output: CORBA.OutputStream;
const _Value: Myrdv_i.data_record);
var
  L0 : Cardinal;
  I0 : Cardinal;
 i : Integer;
 l : Integer;
 s : String;
begin
  L0 := Length(_Value);
  _Output.WriteULong(L0);
  if (L0 > 0) then
  begin
    for I0 := 0 to High(_Value) do
    begin
 If VarType (_Value[I0]) = varString Then
  Begin
   s := String (_Value[I0]);
   l := Length (s);
   _Output.WriteLong (18);
   _Output.WriteLong (0);
   _Output.WriteLong (l+1);
   For i:=1 To l Do _Output.WriteChar (s [i]);
   _Output.WriteOctet (0);
  End
   Else
      _Output.WriteAny(_Value[I0]);
    end;
  end;
end;
