datareader to load listbox - thread safety

How about putting data in a datatable first, then use invoke method.

i have a sqldatareader that could potentially pull in many rows,
maybe thousands, and put them into a listBox on a windows form. i
want to do it as fast as possible so right away i think about a new
thread. well scratch that, fast i can't really control. i want the
user interface to remain responsive during the sqldatareader load.
after it loads, i do this

Do While drReader.Read
Me.lstValues.Items.Add(drReader.Item(0))
Loop

to fill the listbox. my question is, if i load the datareader on a
worker thread i DO have to use the .Invoke method because this isn't
thread safe right? is there a better way to load the list box than
i am thinking?
