Subscription.Initialize Method

Article
12/03/2008

Initializes an instance of the Subscription class with a reference to an NSApplication and the name of a subscription class. Is used in conjunction with the parameterless constructor to enable COM interoperability.

Namespace: Microsoft.SqlServer.NotificationServices
Assembly: Microsoft.SqlServer.NotificationServices (in microsoft.sqlserver.notificationservices.dll)

Syntax

'Declaration
Public Sub Initialize ( _
    nsApplication As NSApplication, _
    subscriptionClassName As String _
)

public void Initialize (
    NSApplication nsApplication,
    string subscriptionClassName
)

public:
virtual void Initialize (
    NSApplication^ nsApplication, 
    String^ subscriptionClassName
) sealed

public final void Initialize (
    NSApplication nsApplication, 
    String subscriptionClassName
)

public final function Initialize (
    nsApplication : NSApplication, 
    subscriptionClassName : String
)

Parameters

nsApplication
An NSApplication representing the Notification Services application to which the Subscription object provides subscription data.

subscriptionClassName
A string containing the name of the subscription class that defines the subscription data that the Subscription object provides. This determines what subscription fields this Subscription object exposes.

Remarks

The Initialize method is used in conjunction with the parameterless constructor to enable COM interoperability. It must be called before any other property or method is called on a Subscription object created with the parameterless constructor.

Example

The following example shows how to create and initialize a Subscription in unmanaged Microsoft Visual Basic Scripting Edition (VBScript) code:

Dim testInstance, testApplication, testSubscription, subscriptionId

const instanceName = "Tutorial"
const applicationName = "Weather"
const subscriptionClassName = "WeatherCity"

' Create the NSInstance object.
set testInstance = WScript.CreateObject( _ 
    "Microsoft.SqlServer.NotificationServices.NSInstance")
testInstance.Initialize instanceName

' Create the NSApplication object.
set testApplication = WScript.CreateObject( _ 
    "Microsoft.SqlServer.NotificationServices.NSApplication")
testApplication.Initialize (testInstance), applicationName

' Create the Subscription object.
set testSubscription = WScript.CreateObject( _
    "Microsoft.SqlServer.NotificationServices.Subscription")
testSubscription.Initialize (testApplication), subscriptionClassName
