  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Load an existing advertisement object using the SMS_Advertisement Server WMI Class class.

  3. Modify the AdvertFlags property using the hexadecimal value for OVERRIDE_MAINTENANCE_WINDOW.

  4. Save the modified advertisement and properties.

Example

The following example method configures an existing advertisement to override maintenance windows.

Important

The hexadecimal values that define the AdvertFlags property are listed in the SMS_Advertisement Server WMI Class class reference material.

Sub ModifyAdvertisementToOverrideMaintenanceWindows(connection,             _
                                                    existingAdvertisementID)
    
    ' Define a constant with the hex value for the OVERRIDE_MAINTENANCE_WINDOW. 
    OVERRIDE_MAINTENANCE_WINDOWS = &H00100000

    ' Get the specific advertisement instance to modify. 
    Set advertisementToModify = connection.Get("SMS_Advertisement.AdvertisementID='" & existingAdvertisementID & "'")
    
    ' List the existing property values.
    Wscript.Echo " "
    Wscript.Echo "Values before change: "
    Wscript.Echo "--------------------- "
    Wscript.Echo "Advertisement Name:            " & advertisementToModify.AdvertisementName
    Wscript.Echo "Advertisement Flags: (integer) " & advertisementToModify.AdvertFlags
    
    ' Set the new property value.
    advertisementToModify.AdvertFlags = advertisementToModify.AdvertFlags OR OVERRIDE_MAINTENANCE_WINDOWS
    
    ' Save the advertisement.
    advertisementToModify.Put_ 
    
    ' Output the new property values.
    Wscript.Echo " "
    Wscript.Echo "Values after change:  "
    Wscript.Echo "--------------------- "
    Wscript.Echo "Advertisement Name:             " & advertisementToModify.AdvertisementName
    Wscript.Echo "Advertisement Flags (integer):  " & advertisementToModify.AdvertFlags

End Sub

public void ModifySWDAdvertisementToOverrideMaintenanceWindows(WqlConnectionManager connection, 
                                                               string existingAdvertisementID)
{
    // Define a constant with the hex value for OVERRIDE_MAINTENANCE_WINDOW. 
    const Int32 OVERRIDE_MAINTENANCE_WINDOWS = 0x00100000;
    
    try
    {
        // Get the specific advertisement instance to modify. 
        IResultObject advertisementToModify = connection.GetInstance(@"SMS_Advertisement.AdvertisementID='" + existingAdvertisementID + "'");

        // List the existing property values.
        Console.WriteLine();
        Console.WriteLine("Values before change:");
        Console.WriteLine("_____________________");
        Console.WriteLine("Advertisement Name:            " + advertisementToModify["AdvertisementName"].StringValue);
        Console.WriteLine("Advertisement Flags (integer): " + advertisementToModify["AdvertFlags"].IntegerValue);

        // Modify the AdvertFlags value to include the OVERRIDE_MAINTENANCE_WINDOWS value.
        advertisementToModify["AdvertFlags"].IntegerValue = advertisementToModify["AdvertFlags"].IntegerValue | OVERRIDE_MAINTENANCE_WINDOWS;

        // Save the advertisement with the new value.
        advertisementToModify.Put();

        // Reload the advertisement to verify the change.
        advertisementToModify.Get();
                        
        // List the existing (modified) property values.
        Console.WriteLine();
        Console.WriteLine("Values after change:");
        Console.WriteLine("_____________________");
        Console.WriteLine("Advertisement Name:            " + advertisementToModify["AdvertisementName"].StringValue);
        Console.WriteLine("Advertisement Flags (integer): " + advertisementToModify["AdvertFlags"].IntegerValue);
    }
    catch (SmsException ex)
    {
        Console.WriteLine("Failed to modify advertisement. Error: " + ex.Message);
        throw;
    }
}
