From: alexia.bee on 23 Mar 2008 18:20 Hi all, I want to be notified using WMI when IP address is being changed. The following code is good for disable/enable device: WqlEventQuery query = new WqlEventQuery("SELECT * FROM __InstanceModificationEvent WITHIN 2 WHERE TargetInstance ISA \"Win32_NetworkAdapter\""); //WqlEventQuery query = new WqlEventQuery("SELECT * FROM __InstanceModificationEvent WITHIN 2 WHERE TargetInstance ISA \"Win32_NetworkAdapterConfiguration\""); // Initialize an event watcher and subscribe to events that match this query ManagementEventWatcher watcher = new ManagementEventWatcher(); watcher.Query = query; while (true) { ManagementBaseObject e = watcher.WaitForNextEvent(); Console.WriteLine("Description:\t\t {0} ", ((ManagementBaseObject)e["TargetInstance"])["Description"]); Console.WriteLine("ConfigManagerErrorCode:\t {0} ", ((ManagementBaseObject)e["TargetInstance"]) ["ConfigManagerErrorCode"]); Console.WriteLine("NetConnectionStatus:\t {0} ", ((ManagementBaseObject)e["TargetInstance"])["NetConnectionStatus"]); } //Cancel the subscription watcher.Stop(); for IP addresss I should use class "Win32_NetworkAdapterConfiguration". any idea how to do it? One more thing. When state is changed to disabled\enabled, I only get Disconnected/Connected Device is working properly/Device is disabled Any idea why I don't get also: Connecting/Disconnecting/Authenticating status thanks. |
