ManagementServer.BeginExecuteDeviceDiscovery Method

Updated: April 16, 2012

Starts an asynchronous operation to discover devices in a specified IP address range. Namespace: Microsoft.EnterpriseManagement.Administration
Assembly: Microsoft.EnterpriseManagement.OperationsManager (in Microsoft.EnterpriseManagement.OperationsManager.dll)Dim instance As ManagementServer Dim discoveryConfigurations As IList(Of DeviceDiscoveryConfiguration) Dim callback As AsyncCallback Dim state As Object Dim returnValue As IAsyncResult returnValue = instance.BeginExecuteDeviceDiscovery(discoveryConfigurations, callback, state)Public Function BeginExecuteDeviceDiscovery ( _ discoveryConfigurations As IList(Of DeviceDiscoveryConfiguration), _ callback As AsyncCallback, _ state As Object _ ) As IAsyncResultpublic IAsyncResult BeginExecuteDeviceDiscovery ( IList<DeviceDiscoveryConfiguration> discoveryConfigurations, AsyncCallback callback, Object state )public: IAsyncResult^ BeginExecuteDeviceDiscovery ( IList<DeviceDiscoveryConfiguration^>^ discoveryConfigurations, AsyncCallback^ callback, Object^ state )public IAsyncResult BeginExecuteDeviceDiscovery ( IList<DeviceDiscoveryConfiguration> discoveryConfigurations, AsyncCallback callback, Object state )public function BeginExecuteDeviceDiscovery ( discoveryConfigurations : IList<DeviceDiscoveryConfiguration>, callback : AsyncCallback, state : Object ) : IAsyncResultParametersdiscoveryConfigurationsDescribes the devices to discover.callbackAn AsyncCallback delegate that references a user-defined method to call when the discovery operation is complete.stateA user-defined object that you can use to pass information about the state of the asynchronous operation to the method specified by the callback parameter.Return ValueReturns an IAsyncResult instance that you can use to check the status of the asynchronous operation.

After you call this method to asynchronously discover network devices, you must call the EndExecuteDeviceDiscovery method to complete the operation. If the discovery process has not yet finished, the method blocks until discovery is complete.

You can determine whether the discovery process has been completed by using the IsCompleted property of the IAsyncResult instance returned by this method.

If you specify a user-defined callback method (in the callback parameter), this method is automatically called when discovery is complete. The specified callback method must accept an IAsyncResult instance as a parameter.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
