I am using SpreadsheetML to generate an Excel spreadsheet with multiple worksheets.
I would like to make the document read only when opened with Excel. How can I do this?
(I appreciate that a user could open the XML file as text and do what they want with it so this is read-only in the loosest sense.)
Thanks
