Visual Basic

Public Sub ChangeWatchedParametersAsync ( _
	serverParameterNamesToAdd As String(), _
	serverParameterNamesToRemove As String(), _
	replaceExisting As Boolean, _
	completedCallback As AsyncCompletedEventHandler, _
	userState As Object _
)

Parameters

serverParameterNamesToAdd: Type: array<System..::..String>[]()[][]
The server parameter names to add. (Can be nullNothingnullptra null reference (Nothing in Visual Basic).)

serverParameterNamesToRemove: Type: array<System..::..String>[]()[][]
The server parameter names to remove. (Can be nullNothingnullptra null reference (Nothing in Visual Basic).)

replaceExisting: Type: System..::..Boolean
if set to trueTruetruetrue (True in Visual Basic), replace the existing list.

completedCallback: Type: System.ComponentModel..::..AsyncCompletedEventHandler
The callback to invoke when the asynchronous operation completes.

userState: 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.

Remarks

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.

Note: This method silently ignores attempts to add items already being watched or to remove items not being watched.

Note
For more information on watches see How Watches Work.
