title: VB.net modify a textfile by using listbox and textbox
body: <p>I want to be able to edit/delete/insert lines of text from a textfile by using listbox and textbox.</p>
  
  <p>I want to display all the contents of the textfile per line in a listbox and when I click a line of text it will then display it in the textbox giving me the option to either edit or delete that line of text.</p>
  
  <p>My insertion of text would be inserted after the last line of text being displayed in the listbox. Is this possible? I just want a starting point and I will continue it from there. Thanks in advance.</p>
