Here's a couple ideas for you. 1. I know this is not what you asked, but why not write a viewer that can show the lines in the log in reverse?
2. I think all the streaming and file io functions assume a fixed start of the file with allocation going forward. You'll probably have to write your own allocation routines and buffering to make this work. I'd look around for the source of some of the defrag utilities that are out there. -----Original Message----- From: Discussion of advanced .NET topics.

For the purpose I looked for ways of doing that but ended up by reading the entire contents of the existing file into a byte array and then re-write the file with the new content. Is there any better way possible? The current code // Firstly read the existing file and take the contents // into a byte array //------------------------------------------------------------ fs = new FileStream(m_strFilePath, FileMode.Open, FileAccess.Read); byte[] arrOriginalText = new byte[fs.Length]; fs.Read(arrOriginalText, 0, arrOriginalText.Length); fs.Close(); fs = null; //------------------------------------------------------------ // Now write the data to the file by re-creating the new file //------------------------------------------------------------ fs = new FileStream(m_strFilePath, FileMode.Create, FileAccess.Write); // Convert the new data to be written to a byte array //------------------------------------------------------------ byte[] arrNewText = new byte[ strData.Length ]; Encoding.UTF8.GetBytes( strData, 0, strData.Length, arrNewText, 0 ); // Now write data - first the new text and then the original //------------------------------------------------------------ fs.Write(arrNewText, 0, arrNewText.Length); fs.Write(arrOriginalText, 0, arrOriginalText.Length); //------------------------------------------------------------ Any suggestion would be highly appreciated Thanks in advance Regards, Girish Jain =================================== This list is hosted by DevelopMentorR http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
