I would suggest using a memory-mapped file. You could then do all your manipulation in memory then have Windows dump the memory back out to the file.
.NET 1.1 doesn't have inherent support for memory-mapped files; but there's at least one class that wraps the required PInvoke code: http://www.winterdom.com/dev/dotnet/FileMap-2.0.2.zip at http://www.winterdom.com/dev/dotnet/. That class only gives access to the memory via a Stream object; but it's a good place to start. http://www.peterritchie.com/ On Fri, 18 Nov 2005 12:22:18 +0000, Girish Jain <[EMAIL PROTECTED]> wrote: >Hi All, > >I am writing a log file with the requirement that the latest entry in the >log should be on the top.
