disable enable network connections?

hi all,

I will like to create a function to disable/enable network connection in my program.I've tried a test code sample but it does not work and I suspect I did not properly included and link the necessary headers and libs..

Qt Code:

Switch view

#include <windows.h>
#include <iphlpapi.h>    
#include <objbase.h>
#include <netcon.h>      
#include <stdio.h>
.....
void disableNIC(char * AdapterName) 
{
INetConnectionManager* pNet;
INetConnection* pConn;
IEnumNetConnection* pEnum;
NETCON_PROPERTIES* pProps;
wchar_t Temp[255];
ULONG uCount = 0;
 
swprintf(Temp, L"%S", AdapterName);
CoInitialize(NULL);
CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, IID_INetConnectionManager, (void**)&pNet);
//CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, __uuidof(INetConnectionManager), (void**)&pNet);
pNet->EnumConnections(NCME_DEFAULT, &pEnum);
....
...
}

#include <windows.h>
#include <iphlpapi.h>    
#include <objbase.h>
#include <netcon.h>      
#include <stdio.h>
.....
void disableNIC(char * AdapterName) 
{
INetConnectionManager* pNet;
INetConnection* pConn;
IEnumNetConnection* pEnum;
NETCON_PROPERTIES* pProps;
wchar_t Temp[255];
ULONG uCount = 0;

swprintf(Temp, L"%S", AdapterName);
CoInitialize(NULL);
CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, IID_INetConnectionManager, (void**)&pNet);
//CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, __uuidof(INetConnectionManager), (void**)&pNet);
pNet->EnumConnections(NCME_DEFAULT, &pEnum);
....
...
}

To copy to clipboard, switch view to plain text mode

it has an error with "undefined referenced to CLSID_ConnectionManager" and "IID_INetConnectionManager",or _uuidof was not declared in this scope.

I've included objbase.h and netcon.h and have added libole32.a to my Lib directory and I linked it like this: win32:LIBS += -Ld:/Path/Lib -liphlpapi -lole32 -lnetshell
Is there anything that I've missed and how to solve it?

Is there any functions in Qt that can be used to disable/enable connections instead?

Appreciate any advice.
