 Unable to perform SetExtension(dnsServers,value).
 Is this supported or is it limited only to OPTIONAL?

 Thanks in Advance

Re: [protobuf] Unable to perform SetExtension on 'repeated inside extensions'.

['Adam Cozzette' via Protocol Buffers]

I think the MutableExtension() method is the way to go; that will return a
pointer to your extension field, so in this case a pointer
to DNSServerNames. Something like this should work:

i->MutableExtension(dnsServerNames)->add_dnsservers("aaa");

Or you could also do it like this:

DNSServerNames temp;
temp.add_dnsservers("aaa");
*i->MutableExtension(dnsServerNames) = temp;

Re: [protobuf] Unable to perform SetExtension on 'repeated inside extensions'.

[sachin . p . puranik]

Hi Adam,
Please find the below snippet and the associated error:
//Code

IpInterfaceAddress *i = dynamic_cast 
(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 
(x); //x is of type google::protobuf::Message *
if(i != NULL)
{
i->AddExtension(dnsServerNames,(char*)value );
}

//error
error C2664: 'void 
IpInterfaces::IpInterfaceAddress::AddExtension(const
 
google::protobuf::internal::ExtensionIdentifier

'char *' to 'const IpInterfaces::DNSServerNames &'
  with
  [
  Type=IpInterfaces::DNSServerNames,
  ExtendeeType=IpInterfaces::IpInterfaceAddress,

  ]
  Reason: cannot convert from 'char *' to 'const

  No constructor could take the source type, or constructor 
overload resolution was ambiguous
