Hi all.

I have a problem with the any type and user defined types. I do not find the
opertors <<= and >>= for the user defined types.

Here a simple example:

in IDL:

struct userDefinedTest
{
  string a;
  string b;

In my Code:
CORBA::Any a;
userDefinedTest test;

a <<= test;

produces the error
E2094 'operator<<=' not implemented in type 'CORBA_Any' for arguments of type
'userDefinedTest'

What have I to do so that the IDL compiler generates the stubs for overloading
user defined types?

Thank you,
Carsten Wolters

Hi. You can't direct use next syntax CORBA::Any a <<= "my struct" becouse
operator <<= "my type" is not defined. You must convert your type in
sequence<octet> (or use valuetype in IDL and send your type by value, only
VB4.0) and then write or read value to or from Any.
Example

      // Count of elments
      //
      DWORD cElements = sizeof("My struct");

      // Allocate the memory to hold the sequence
      CORBA::ULong value_len = cElements + sizeof(CORBA::ULong);
      char *value = new char[value_len];
      void *ptr = value;

      // Copy the element count
      *(CORBA::ULong *)ptr = cElements;
      ((CORBA::ULong *)ptr)++;

      // Copy the data
      memcpy(ptr, "My struct", cElements);

      // Create an any with the value
      CORBA_TypeCode_var etc = new CORBA_TypeCode(CORBA::tk_octet, 0);
      CORBA_TypeCode_var tc = CORBA::ORB::create_sequence_tc(0, etc);
      CORBA_MarshalInBuffer ibuf(value, value_len);
      any.read_value(ibuf, tc);

      delete[] value;
