Seems pretty clear to me: `10:57:49 Perl Open E:\GMS\TESTMEMBER\GMS.LOG 10:57:49 Perl Open E:\GMS\TESTMEMBER\GMS.LOG 10:57:49 Perl Close E:\GMS\TESTMEMBER\GMS.LOG 10:58:10 Perl Rename E:\GMS\TESTMEMBER\GMS.LOG` [download] You open GMS.LOG twice, only close it once, then try to rename it (when you still have it open at least once). The default for C programs under Win32 is to allow "read" and "write" sharing but not "delete" sharing. And if a file is currently open w/o "delete" sharing having been requested, then no one (not even the process that has the file open) is allowed to delete or even rename the file. So you need to find which of your two file handles you are failing to close before you rename the file. FYI, Win32API::File has more information on Win32 file sharing and ways to open files while specifying different levels of file sharing. Elsewhere you asked about the "archive" bit. If the archive bit is set, that means that a file has been modified since the last time it was archived. That is, modifying the contents of a file sets the archive bit and many "backup" programs clear the archive bit when they copy the file. Also, many backup programs can be told to only backup files who have the archive bit set (which is where this whole scheme becomes useful). - tye (but my friends call me "Tye")	[reply] [d/l]
This is odd by Flame (Deacon) on Dec 04, 2001 at 02:43 UTC
This is kinda confusing, I tried spescifically closing the file before and it didn't work... but now... it does... I'm kinda confused there... mabey I just closed it wrong... `-----BEGIN GEEK CODE BLOCK----- Version: 3.12 GIT d- s:++ a--- C++++ UL P+++>++++ L+ E- W++>+++ N !o K- w+ O---- M-- V-- PS PE Y- PGP t++(+++) 5(+++)++++ X R+@ tv+ b+++ DI+ D- G e->+++ h! r-- y- ------END GEEK CODE BLOCK------` Translate "Weird things happen, get used to it."

I'm not sure if I am reading this correctly either, but have you checked to see what the permissions of `E:\GMS\TESTMEMBER\GMS.BAK` are? If it is read only and the rename is trying to overwrite it, it might be the source of the problem. HTH. --Jim	[reply]

It's only "Archive"... whatever that's suppost to mean... (If anyone cares to tell me what the archive setting really does, feel free) `-----BEGIN GEEK CODE BLOCK----- Version: 3.12 GIT d- s:++ a--- C++++ UL P+++>++++ L+ E- W++>+++ N !o K- w+ O---- M-- V-- PS PE Y- PGP t++(+++) 5(+++)++++ X R+@ tv+ b+++ DI+ D- G e->+++ h! r-- y- ------END GEEK CODE BLOCK------` Translate "Weird things happen, get used to it."

Sorry. I can't help you with it. I've been Win32 programmer in my previous life and I hardly remember what it is about. -- Ilya Martynov (http://martynov.org/)	[reply]
