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 "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;
    }
}
