Marty Hi everybody, Is it possible to do that in VB.NET: I have a text file that is filled with new lines of text every n seconds. This text file get very massive. I want to have my program to monitor this text file and to be able to read only the new added line when it detect that a new line has been added. I don't want to read the whole file every time, this would be high time consuming. Any idea? Thanks you very much! Marty Reply to this message...        Herfried K.

Then you can use the 'FileStream''s 'Seek' method or 'Position' property to read data beginning at the position where the file ended the last time you read it. -- M S Herfried K.

I have another question, how can I be sure that by reading the file, I don't interrupt the other process who want to add a text line to it? This is my reader object settings: Dim fs As New FileStream(strFilePath, FileMode.Open, FileAccess.Read) Dim ioFileIN As StreamReader = New StreamReader(fs) Is there anything else that I can set to have my ioFileIN not holding the file while reading?
