It´s not easy to understand you.
If you want to compare the text in the different lines of your textfile, i think you should use TextFile.ReadToTable () and later you can use the String.Compare () and other String- functions to find and change lines in this file.

sorry but it is not easy for me in English, compared the lines, if the line is different, modify the line and then save

thanx

Maybe you could use TextFile.ReadToString, then use String.Replace to change the text, then use TextFile.WriteFromString to write the changed text back to the text file?
