The following example shows how to list the maintenance windows for a specific collection by using the SMS_CollectionSettings Server WMI Class class. Maintenance windows are created by using the SMS_ServiceWindow Server WMI Class class and then stored as embedded objects in SMS_CollectionSettings instances, one per collection.

To list the maintenance windows and properties for a collection

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Get the existing collection settings instance by using the collection ID provided.
Enumerate the existing service window objects and properties.

Note

The example method includes additional steps, primarily to handle the overhead of dealing with the service window objects, which are stored as embedded objects in the collection settings instance.

Example

The following example method lists the maintenance windows and properties for a collection.

Sub ListMaintenanceWindowsAndPropertiesForASpecificCollection(connection,         _
                                                              targetCollectionID)
                                       
    ' Build a query to get the specified collection. 
     collectionSettingsQuery = "SMS_CollectionSettings.CollectionID='" & targetCollectionID & "'"
     
    ' Get the collection settings instance for the targetCollectionID.
    Set allCollectionSettings = connection.ExecQuery("Select * From SMS_CollectionSettings Where CollectionID = '" & targetCollectionID & "'")  
   
    ' If a collection settings instance does not exist, output a message.
    If allCollectionSettings.Count = 0 Then
        Wscript.Echo "There are no maintenance windows for collection: " & targetCollectionID
    Else             
    
    ' Get the specific collection settings instance.
    Set collectionSettingsInstance = connection.Get("SMS_CollectionSettings.CollectionID='" & targetCollectionID &"'" )
    
        ' Populate the local array list with the existing service window objects (from the target collection).
        tempMaintenanceWindowArray = collectionSettingsInstance.ServiceWindows 

        ' Enumerate through the array list to access each maintenance window object.
        For Each maintenanceWindow in tempMaintenanceWindowArray   
   
                Wscript.Echo "Maintenance Window Properties "
                Wscript.Echo "----------------------------- "
                Wscript.Echo "Name:              " & maintenanceWindow.Name
                Wscript.Echo "Description:       " & maintenanceWindow.Description
                Wscript.Echo "Service Window ID: " & maintenanceWindow.ServiceWindowID

                Wscript.Echo " "

        Next
    
    End If

    {
        Console.WriteLine("Failed. Error: " + ex.InnerException.Message);
        throw;
    }
}
