    Persistent File I/O - Possible

    I would like, if possible to attach to a log file and read newly created data from it. For instance, I have a third party application that on occasion writes to a log file. I would like to find out when the file was written to, then explicitly get the new data\line to write to a listbox. Is this possible?

    I can use the FileSystemWatcher to flag the change, but how do I explicitly pull the new data from the file and leave all the rest behind. Also, these files could be quite large, 5 meg plus in some instances.

    Why not store the file length inbetween opening, then the next time you open it you can skip x amount of bytes or space according to how long the file used to be.
