Question

Well im working on a project for school and im almost done except for like 2 forms and alot of debugging, well anyway im having a prob when it reads each line of a .txt or .csv file and writes it to an assigned text box and vise versa, anyway when it writes the text, after every word in each text box there are these tiny boxes - [] - but smaller, almost like ascii, if anyone can tell me if its the code or if it always does this etc etc, im open for suggestions, if u want a look at the code i have just make a reply cause its alot, thanks
