} *fixedObject;

int wmain(int argc, wchar_t* argv[])
   unsigned int error;
   const char16_t *userName = u"UserName", *message;
   char16_t buffer[128];
   CODBPP::Object object;
   CODBPP database;
   if((error = database.BeginTransaction()) == NO_ERROR
   && (error = database.OpenTable(FIRST_TABLE)) == NO_ERROR
   && (error = database.ReadObject(FIRST_TABLE,
           CODBPP::EQUALTO,&object,1,userName)) == NO_ERROR){
      fixedObject = (struct FixedObject*)object.fixed;
      swprintf(buffer,u"First = %d, Second = %g",
