Writing single line inside a text file

[ChrisW67]

You can only randomly update the file if the space already exists for the data you are inserting. If the file size needs to change (longer or shorter) then there is no way to avoid rewriting the entire file.

if you know a better way of creating a blanck QString without having to use a for with append(" "), I'ld be glad to know

QString blanks(80, ' ');
QString hyphens(80, '-');

QString blanks(80, ' ');
QString hyphens(80, '-');

To copy to clipboard, switch view to plain text mode
