INetworkConnectionEvents Supports what? - c++

Question

I'm trying to use this API; however, I cannot get the events to fire.
So this is using Network List 1.0 Type Library com.
Here is my code:
public class AvailibleWLan : INetworkListManagerEvents, INetworkEvents, INetworkConnectionEvents
{
public NETWORKLIST.INetworkListManager NewWorkList {get;set;}
public List<WirelessNetwork> Connections { get; set; }
public AvailibleWLan()
{
Connections = new List<WirelessNetwork>();
NewWorkList = new NETWORKLIST.NetworkListManager();
foreach (NETWORKLIST.INetwork Network in NewWorkList.GetNetworks(NETWORKLIST.NLM_ENUM_NETWORK.NLM_ENUM_NETWORK_ALL))
{
String Name = Network.GetName();
var Connectivity = Network.GetConnectivity();
var Description = Network.GetDescription();
}
}
//public event NetworkPropertyChanged NetworkConnectivityChanged;
public WirelessNetwork Network { get; set; }
void INetworkListManagerEvents.ConnectivityChanged(NLM_CONNECTIVITY newConnectivity)
{
throw new NotImplementedException();
}
void INetworkConnectionEvents.NetworkConnectionConnectivityChanged(Guid connectionId, NLM_CONNECTIVITY newConnectivity)
{
throw new NotImplementedException();
}
void INetworkConnectionEvents.NetworkConnectionPropertyChanged(Guid connectionId, NLM_CONNECTION_PROPERTY_CHANGE Flags)
{
throw new NotImplementedException();
}
void INetworkEvents.NetworkAdded(Guid networkId)
{
throw new NotImplementedException();
}
void INetworkEvents.NetworkConnectivityChanged(Guid networkId, NLM_CONNECTIVITY newConnectivity)
{
throw new NotImplementedException();
}
void INetworkEvents.NetworkDeleted(Guid networkId)
{
throw new NotImplementedException();
}
void INetworkEvents.NetworkPropertyChanged(Guid networkId, NLM_NETWORK_PROPERTY_CHANGE Flags)
{
throw new NotImplementedException();
}
}
So i have put a break on all the events. and vs is never breaking out.

you defined all necessary callback functions, thats great. But you have to register for these events with calling the network interface method "advise" for the networks of interest.
Here is a code sample for that:
namespace NetworkListSample
{
class TestNetworkEvents : INetworkListManagerEvents, INetworkConnectionEvents
{
private INetworkListManager m_nlm = new NetworkListManager();
private static Guid s_INetworkListManagerEventsGuid = typeof(INetworkListManagerEvents).GUID;
private static Guid s_INetworkConnectionEventsGuid = typeof(INetworkConnectionEvents).GUID;
public void RegisterForEvents()
{
// Here it will only register for events of a network which is connected,
// if you wish to register for events of disconnected networks
// use a different NLM_ENUM_NETWORK enum value
IEnumNetworks Networks = m_nlm.GetNetworks(NLM_ENUM_NETWORK.NLM_ENUM_NETWORK_CONNECTED);
foreach (INetwork item in Networks)
{
IConnectionPoint cp = null;
IConnectionPointContainer icpc = (IConnectionPointContainer)m_nlm;
int cookie = -1;
Guid tempGuid = s_INetworkListManagerEventsGuid;
icpc.FindConnectionPoint(ref tempGuid, out cp);
cp.Advise(this, out cookie);
}
}
public void ConnectivityChanged(NLM_CONNECTIVITY newConnectivity)
{
throw new NotImplementedException();
}
public void NetworkConnectionConnectivityChanged(Guid connectionId, NLM_CONNECTIVITY newConnectivity)
{
throw new NotImplementedException();
}
public void NetworkConnectionPropertyChanged(Guid connectionId, NLM_CONNECTION_PROPERTY_CHANGE Flags)
{
throw new NotImplementedException();
}
}
}
Please don't forget the "unadvise" which takes the integer cookie(s) as parameter.
