Workbook.ChangeFileAccess method

Changes the access permissions for the workbook. This may require an updated version to be loaded from the disk.


expression.ChangeFileAccess (Mode, WritePassword, Notify)

expression A variable that represents a Workbook object.


Name Required/Optional Data type Description
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.

ActiveWorkbook.ChangeFileAccess Mode:=xlReadOnly
