    Default Modifying file with Qt

    Hi,

    I need to read certain text from a file, and "remember" the line (nLine) where that text is found in the file. Then on the next line (nLine+1) I need to insert other line of text. I can make copy out of the file and then remove (delete) the "older" and rename the new file, but that is not applicable atm. Is there any way to do "real-time" search/modify for a text in a file?

    thanks

    Yes there is.
    RTFM:
    QFile
    QTextStream

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.
