Exemple
The following example shows how to use the GetFieldValue method in unmanaged Microsoft Visual Basic Scripting Edition (VBScript) code to get the value of a subscription field:
Dim myInstance, myApplication, mySubscription, fieldValue
const instanceName = "MyInstanceName"
const applicationName = "MyApplicationName"
const subscriptionClassName = "MySubscriptionClassName"
const fieldName = "MySubscriptionFieldName"
'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 a Subscription object.
set mySubscription= WScript.CreateObject("Microsoft.SqlServer.NotificationServices.Subscription")
mySubscription.Initialize (myApplication), subscriptionClassName
mySubscription.SubscriptionId = "1"
fieldValue = mySubscription.GetFieldValue(fieldName)
