Creating Outlook Contacts

I have a project which requires creating and possibly modifying a large number of contacts. I'm planning on taking the name and e-mail address for each contact from a text file. Does anyone know how to use either VB or VBscript to create a contact? How about modifying a contact?

Thanks

VB Code:

Private o1 As Outlook.Application
 
Private Function CreateContact(Name As String, Nick As String, Email As String, Optional Folder As Outlook.MAPIFolder = Nothing) As Outlook.ContactItem
   'Create a new contact item
    If Folder Is Nothing Then
        Set CreateContact = o1.CreateItem(olContactItem)
    Else
        Set CreateContact = Folder.Items.Add(olContactItem)
    End If
    'Set a few of the many possible contact parameters.
    CreateContact.FullName = "Name"
    CreateContact.NickName = "NickName"
    CreateContact.Email1Address = "Email"
    'Commit the contact
    CreateContact.Save
End Function
