If you're writing a file manager for VFS, you need to know this if you want to copy a file from the card to RAM (if you want to be nice and tell the user things). Deleting the file would be dangerous, just in case it works, and that's not what the user wanted to do ;) If you're writing a backup program, I want to know if a file is protected to decide weather or not to back it up / restore it. I would also like to be able to restore "open"/"protected" databases like "Net Prefs" and such, then reset when done... The above are examples from when -I've- needed to know :P - but there are probably many other examples available if you hunt around. > 1) On OS4 listen out for the sysNotifyDeleteProtectedEvent when you try to > delete it. This relates to another discussion (...Visual Basic...? ;) - I like to support devices as old as OS 3.0, as that was the first [Palm] device I ever had, and I seriousally doubt that there are many OS 1/2 devices still flying around. > 2) Call DmDatabaseProtect(cardNo, dbID, false) and see if it returns > errNone or dmErrDatabaseNotProtected.

It'll hopefully pay off the bandwidth use :P > 3) If you have the Palm OS source have a look at the function > PrvDatabaseIsProtected() and see if you can use something similar to that - > I'm not convinced you can as it uses system globals. The Palm source code is always an entertaining read. I especially like some of the comments from the developers (the values of the notifications are quite amusing). I like how cheap (read: fast/simple/elegant) the SysRandom function is. -- Matthew (Darkstorm) Bevan [EMAIL PROTECTED] Margin Software, NECTI. http://www.marginsoftware.com Re-inventing the wheel, every time. - All the passions make us commit faults; love makes us commit the most ridiculous ones. -- La Rochefoucauld -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
