expression.ChangeFileAccess (Mode, WritePassword, Notify)
expression A variable that represents a Workbook object.
|Mode||Required||XlFileAccess||Specifies the new access mode.|
|WritePassword||Optional||Variant||Specifies the write-reserved password if the file is write reserved and Mode is xlReadWrite. Ignored if there's no password for the file or if Mode is xlReadOnly.|
|Notify||Optional||Variant||True (or omitted) to notify the user if the file cannot be immediately accessed.|
If you have a file open in read-only mode, you don't have exclusive access to the file. If you change a file from read-only to read/write, Microsoft Excel must load a new copy of the file to ensure that no changes were made while you had the file open as read-only.
This example sets the active workbook to read-only.
