Syntax

Finding out whether a file is read-only Hide the details

<Result> = fAttributeReadOnly(<File name>)

<Result>: Boolean

True if the file is read-only,
False otherwise. The ErrorOccurred variable returns True if an error occurred.

<File name>: Character string (with quotes)

Name and full (or relative) path of file (up to 260 characters). A UNC path can be used.

Operating mode in Windows Vista (and later)

If this function does not operate properly in Windows Vista (and later), check whether the file or directory used is not in one of the system directories (Windows directory or "Program Files" directory).

Indeed, in Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have the administrator privileges to handle and/or modify the files or directories in the system directories (Windows directory or "Program Files" directory).

Programming tip: To handle and/or modify the files or directories without administrator privileges, you should:

avoid writing to the Windows directory or to the "Program Files" directory,
use the system directory of the application (returned by SysDir with the srAppDataCommun constant, for example).
