PLSanitizeAttachmentName

Data types

Description

PLSanitizeAttachmentName prepares a file name for use as a mail attachment display name

The function strips any leading path, replaces the characters that mail systems and file systems reject, and never returns an empty name

The MailSendDemo passes deliberately hostile names through it before attaching

Function PLSanitizeAttachmentName(Const FileName: WideString): WideString;

FileName	The candidate file name or full path

The sanitised base name

Path separators of both kinds are stripped, so C:\data\report.pdf yields report.pdf

A name that is empty after path stripping, or . or .., becomes document.pdf

Control characters below 32 and the characters <>:"/\|?* are each replaced with an underscore
