I wrote an application which uses text files. I know how to read and write into these files. But when I already have put some text in these files, I want to add a new line of text between the text that is already in these files. So I want to jump to a line and put the new line of text at this line between the other lines of text. The same counts for reading. How do I read the text from a line somewere between the other lines of text and put this line of text in a string variable?
Does anyone know how to do this?
