WMI Exception "Not supported " RRS feed

  • Question

  • Hello

    I try to get some data from WMI (wireless signal strength).

    No metter which code I'm using, it is allways throw the next:


    Not supported

    at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)

    it's happen me on winXp,win7

    The code is

     ManagementObjectSearcher searcher = null;
          // Query the management object with the valid scope and the correct query statment  
          searcher = new ManagementObjectSearcher(@"root\WMI", "select Ndis80211ReceivedSignalStrength from MSNdis_80211_ReceivedSignalStrength where active=true");
          // Call the get in order to populate the collection  
          ManagementObjectCollection adapterObjects = searcher.Get();
          // Loop though the management object and pull out the signal strength  
          foreach (ManagementObject mo in adapterObjects)
            returnStrength = Int32.Parse(mo["Ndis80211ReceivedSignalStrength"].ToString());

    I checked out the security, and my device should be works with the WMI

    but still nothing

    please  enyone?
