Asynchronously sends a request to the server to change the watched notifications.

Namespace: ININ.IceLib.Connection.Extensions
Assembly: ININ.IceLib (in ININ.IceLib.dll) Version: (


public void ChangeWatchedNotificationsAsync(
	CustomMessageHeader[] typesAdded,
	CustomMessageHeader[] typesRemoved,
	EventHandler<AsyncCompletedEventArgs> completedCallback,
	Object userState
Visual Basic
Public Sub ChangeWatchedNotificationsAsync ( _
	typesAdded As CustomMessageHeader(), _
	typesRemoved As CustomMessageHeader(), _
	completedCallback As EventHandler(Of AsyncCompletedEventArgs), _
	userState As Object _


Type: array<ININ.IceLib.Connection.Extensions..::..CustomMessageHeader>[]()[][]
The notification types to add.
Type: array<ININ.IceLib.Connection.Extensions..::..CustomMessageHeader>[]()[][]
The notification types to remove.
Type: System..::..EventHandler<(Of <(<'AsyncCompletedEventArgs>)>)>
The callback to invoke when the asynchronous operation completes.
Type: System..::..Object
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.


For further details see CustomNotification.

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 AsyncCompletedEventArgs-derived object 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.

For more information on watches see How Watches Work.


System..::..ArgumentNullExceptionA parameter is nullNothingnullptra null reference (Nothing in Visual Basic).
