[2008] Adding to a listbox

[overgrown]

Hey guys
i am starting to use VB for a uni assignment. this is the first time i have used it.
i am having trouble with it, and cant find tutorials on the net suitable to my version of VB (2008 express)

My first question, one of many

how do i make the list box editible by the user
i want to add to the listbox by adding in a textbox and clicking the 'add student' button.
then able to remove options by selecting them and clicking the 'remove'

when i exit the form and return to the menu form i want the contents of the list box to be avilable from all other forms, so where would this be saved.

i have attached a picture of the form to help you understand.


thanks for the help in advanced.
also if you know of any good tutorials that i could use to save your time.

Thanks !
