Hi Adam,
Please find the below snippet and the associated error:
//Code
IpInterfaceAddress *i = dynamic_cast<IpInterfaceAddress*>
(x); //x is of type google::protobuf::Message *
if(i != NULL)
{
DNSServerNames temp;
temp.add_dnsservers("aaa");
i->MutableExtension.SetExtension(a);
}
//Error:
error C2228: left of '.SetExtension' must have class/struct/union
And tried following as well
//code:
IpInterfaceAddress *i = dynamic_cast<IpInterfaceAddress*>
(x); //x is of type google::protobuf::Message *
if(i != NULL)
{
i->AddExtension(dnsServerNames,(char*)value );
}
//error
error C2664: 'void
IpInterfaces::IpInterfaceAddress::AddExtension<google::protobuf::internal::MessageTypeTraits<Type>,11,false>(const
google::protobuf::internal::ExtensionIdentifier<ExtendeeType,TypeTraitsType,field_type,is_packed>
&,const IpInterfaces::DNSServerNames &)' : cannot convert parameter 2 from
'char *' to 'const IpInterfaces::DNSServerNames &'
with
[
Type=IpInterfaces::DNSServerNames,
ExtendeeType=IpInterfaces::IpInterfaceAddress,
TypeTraitsType=google::protobuf::internal::MessageTypeTraits<IpInterfaces::DNSServerNames>,
field_type=11,
is_packed=false
]
Reason: cannot convert from 'char *' to 'const
IpInterfaces::DNSServerNames'
No constructor could take the source type, or constructor
overload resolution was ambiguous
Regards,
Sachin
