External Events Example

The following Visual Basic Scripting Edition (VBScript) example illustrates how to retrieve an event notice indicating that a publishing point has been created.

Dim WithEvents eventSink As SWbemSink

Private Sub eventSink_OnObjectReady(ByVal obj As 
                       WbemScripting.ISWbemObject, ByVal ctx As 
                       WbemScripting.ISWbemNamedValueSet)

    Dim Prop as SWbemPropertySet
    Set Prop = obj.Properties_
    Call MsgBox "Administrator " + Prop("Administrator").Value +_
                     "created publishing point ‘" +_
                     Prop("PublishingPointName").Value + "’ at " +_
                     Prop("Time")
End Sub

Private Sub Form_Load()
    Set eventSink = New SWbemSink
    Set Services = GetObject
                ("WINMGMTS:{impersonationLevel=impersonate}! _
                 \\.\Root\cimv2")
    Services.ExecNotificationQueryAsync eventSink, "select * _
    from WMS_Publishingpoint_Event Where SubEvent = ""Add"""
End Sub

The following example illustrates how to select only play events for content named Movie.wmv and display the name of the client and the IP address.

    set events = GetObject
                ("winmgmts:{impersonationLevel=impersonate}! _
                \\.\Root\cimv2"). _
                ExecNotificationQuery ("select * from WMS_Client_Event _
                where SubEvent = ""Play"" And Filename = ""Movie.wmv""")

do
    set playevent = events.nextevent 
    if err <> 0 then
        WScript.Echo Err.Number, Err.Description, Err.Source
        Exit Do
    else
    WScript.Echo "Client at " + playevent.Properties_("ClientIP").value _
             + " asked to play " + playevent.Properties_("Title")
    end if
loop
