INetworkConnectionEvents Supports What?

Question

I am trying to use this API; however, I cannot get events to shoot. So this is using the List List List List 1.0 library.

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 put a break on all events. and vs never flashes.

You have defined all the necessary callback functions, which is great. But you must register for these events by invoking the “advise” network interface method for networks of interest.

Here is a sample code for this:

 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 do not forget "unadvise", which accepts integer cookies as a parameter.
