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

Syntax

'Declaration
Public Sub Initialize ( _
    nsApplication As NSApplication, _
    providerName As String, _
    eventClassName As String, _
    eventSchema As String _
)

public void Initialize (
    NSApplication nsApplication,
    string providerName,
    string eventClassName,
    string eventSchema
)

public:
void Initialize (
    NSApplication^ nsApplication, 
    String^ providerName, 
    String^ eventClassName, 
    String^ eventSchema
)

public void Initialize (
    NSApplication nsApplication, 
    String providerName, 
    String eventClassName, 
    String eventSchema
)

public function Initialize (
    nsApplication : NSApplication, 
    providerName : String, 
    eventClassName : String, 
    eventSchema : String
)

Parameters

nsApplication
An NSApplication that represents the Notification Services application to which this EventLoader submits events.

providerName
A string containing the name of the event provider for this EventLoader object.

eventClassName
The event class that defines the structure of the events that this EventLoader submits.

eventSchema
A string representing the path and name of a SQL-annotated XML schema file. This schema file must contain the event class schema, and is used to map the event data in the XML document to the event fields.

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 an EventLoader object created with the parameterless constructor.

Example

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

Dim myInstance, myApplication, myEventLoader

const instanceName = "MyInstanceName"
const applicationName = "MyApplicationName"
const eventProviderName = "MyEventProviderName"
const eventClassName = "MyEventClassName"
const schemaFile = "MySchemaFilePathAndName"

'Create & initialize an NSInstance object.
set myInstance = WScript.CreateObject("Microsoft.SqlServer.NotificationServices.NSInstance")
myInstance.Initialize instanceName

'Create & initialize an NSApplication object.
set myApplication = WScript.CreateObject("Microsoft.SqlServer.NotificationServices.NSApplication")
myApplication.Initialize (myInstance), applicationName

'Create & initialize an EventLoader object.
set myEventLoader = WScript.CreateObject("Microsoft.SqlServer.NotificationServices.EventLoader")
myEventLoader.Initialize (myApplication), eventProviderName, eventClassName, schemaFile

Thread Safety

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