TFileStream is a worker, very low level class. It is not supposed to do any kind of GUI work and you're not supposed to rely on it for a "message box".
The world would be a pretty confusing place if any low-level class would be allowed to pop it's own message box etc. Just imagine TStringList showing boxes on it's own. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Robert Meek > Sent: Monday, April 03, 2006 10:21 PM > To: [email protected] > Subject: Tfilestream class > > I was writing archiving code using ZipForge components and wanted to > offer the user the ability to accept an over-write of the current archive > made on the same day thus having the same name, or deleting the first and > making a new Archive altogether.
