備註

This method is provided for COM interoperability, to allow callers from unmanaged code to get field values from a subscription record. Managed callers do not use this method.

範例

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)
