Menu Driven Program - Visual Basic

name and phone numbers should be read into the program in "memberphones.txt" and should be displayed in a listbox when the form is loaded

to delete a person, they should be highlighted and the delete button should delete them from the list box and array

to modify a person, they should highlight the person and change the attributes and use the "modify" menu option to save the change

to add a person, type the name and number and select "add"

Lastly, hit exit and the program should write out the updated member name and phone numbers to a new file. I'm almost done - I can't find out how to add/delete or modify names and numbers and save them in the memory space for output into a text file.
