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.

Remarks

Notes

This function is faster than fAttribute.

In Windows 98 or Me, this function may fail if a Unicode string is used for the <File name> parameter.

Operating mode in Windows Vista (and later)

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

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

avoid writing into the Windows directory or into the "Program Files" directory,
use the system directory corresponding to the application (returned by SysDir associated with the srCommonAppData constant).
