Close excel file without prompting to save

I want to close an excel file which I’m exporting programmatically. But I don’t want it to prompt the users whether they want to save the file or not. How can this be achieved?

All suggestions are welcome. Thanks in advance.

Make sure the file is not opened in read only format:http://www-10.lotus.com/ldd/46dom.nsf/55c38d716d632d9b8525689b005ba1c0/59e977b872feb47f85256bbc002574db?OpenDocument
