Hi
I am trying to do bluetooth programming on Microsoft Visual C++ 6.0.
I am using basic functions like WSALookupServiceBegin().
i wrote the code like this
WSAQUERYSET wsaq;
wsaq.dwNameSpace = NS_BTH;

The problem is, the compiler is not recognising NS_BTH and giving compile
time error.
I included the following sets of headers and lib

#include winsock
#include winsock2
#include bthdef
#include BluetoothAPIs.h
#include Ws2bth.h
#pragma comment(lib, "ws2_32.lib")

The same goes with socket creation.
Even if i am trying to create socket using the below code

SOCKET client_socket = socket (AF_BT, SOCK_STREAM, BTHPROTO_RFCOMM);

following error are coming up

error C2065: 'NS_BTH' : undeclared identifier
error C2065: 'AF_BT' : undeclared identifier
error C2065: 'BTHPROTO_RFCOMM' : undeclared identifier

i am not able to understand what else needs to be included.
Is it because of Microsoft stack or some SDK is required?
