opening a new form

how do i open a new form by clicking on an item in a listbox

i have this already:

Protected Sub lstFunctie_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
If lstFunctie.SelectedItem.Value Is "Werknemer" Then
Dim frmWerknemer As New Object
Object.open(frmWerknemer)
'here i need the rest visual gives an error at object.open.... so i'm looking for the remaining little part...

End If
End Sub


Thank you in advance
Erik ...
