Costas, A field in the OFSTRUCT data type returned by the OpenFile function is a 4 byte field named "reserved". In Petzold's book, he says this field is used with the OF_READ flag to compare a file's date/time. Does this mean that it might be possible to somehow use this field to get a file's date/time? Redefining it as a single and using it with format$ seems to always return 12/30/99 12:00pm no matter what the value. Could this just be a long with the number of seconds since some date? BTW, OpenFile when used with the OF_EXIST flag is a great way to test for a file's existence! In FM, I can read the font master file and test each font's files for existence extremely quickly. It reads the master file and tests 197 pfm files for existence in right at 1 second! Makes it real nice to insure new entries in win.ini and atm.ini are for files that truly exist. Also makes creating a VB FileExist function super simple. Function FileExist (filename$) as integer dim oFdat as OFSTRUCT e = OpenFile(filename$, oFdat, OF_EXIST) if e = -1 then FileExist = false else FileExist = true end if End Function –dennis There are 2 Replies.
