備註

This method is provided for COM interoperability, to allow callers from unmanaged code to get field values from an event record.

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 an event field:

Dim myInstance, myApplication, myEvent, fieldValue

const instanceName = "MyInstanceName"
const applicationName = "MyApplicationName"
const eventClassName = "MyEventClassName"
const eventFieldName = "MyEventFieldName"

'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 Event object.
set myEvent = WScript.CreateObject("Microsoft.SqlServer.NotificationServices.Event")
myEvent.Initialize (myApplication), eventClassName

'Use the SetFieldValue method to set a field value.
myEvent.SetFieldValue eventFieldName, "Test"

'Use the GetFieldValue method to return a field value.
fieldValue = myEvent.GetFieldValue(eventFieldName)
WScript.Echo "Field Value = " + fieldValue
