public void StartWatchingAsync(  attributeNames, completedCallback, userState )
Public Sub StartWatchingAsync ( _ attributeNames As (), _ completedCallback As , _ userState As _ )
- Type: array<>()
An array of settings to watch.
The callback to invoke when the asynchronous operation completes.
An optional object that contains state information for this request. This object is a way for the caller to store context information which will be provided to the AsyncCompleted event. If no context information is desired then nullNothingnullptra null reference (Nothing in Visual Basic) may be supplied.
When completed, the completedCallback delegate is invoked on a thread appropriate to the application-model, such as the GUI thread in a UI application. The Error property of the passed to the delegate will contain any exceptions thrown while executing the asynchronous task. See the synchronous version of this method for more detailed error information. For more information on async method calls, see How Async Calls Work.
|All event handlers should be added before calling StartWatching(array<String>()) or .|
Derived classes have attribute classes which define the attributeNames strings each derived class can support. Custom strings may also be used for custom handlers. For a list of derived classes and their associated attribute classes see the StartWatching(array<String>()) method.

|A parameter is nullNothingnullptra null reference (Nothing in Visual Basic).|
