when i start my application i want the listbox to take all the folder names in c:\items

so if c:\items contains the folders d2, d3, d4 etc

will the listbox have d2, d3, d4 in it when i start my program
and if i exit my program and create a new folder called s7 in c:\items\ will s7 be in the listbox also when i start my porgram again

anyone know how to do that?
