Hi.

You can do a select case on the selected text.

VB Code:
  1. Select Case Listbox1.Text
  2.     Case "Item1"
  3.         'Open form 1
  4.  
  5.     Case "Item2"
  6.         'Open form 2
  7.  
  8.     'Just keep on going until you have no more items.
  9.  
  10. End Select

I Hope this helps you on your way.
