Sample VB Script • Get some e. Directory information Private Sub Command. Buttone. Directory. Info_Click() Text. Box 1. Text = NWDir 1. Login. Name Text. Box 2. Text = NWDir 1. Full. Name Text. Box 3. Text = NWDir 1. Tree. From. Full. Name( _ NWDir 1. Full. Name) End Sub

Sample VB Script (cont. ) • List e. Directory objects in current container Private Sub Command. Button. Browse_Click() Dim entry As NWEntry List. Box 1. Clear For Each entry In NWDir 1. Entries List. Box 1. Add. Item(entry. Short. Name) Next End Sub

Sample VB Script (cont. ) • Read an e. Directory attribute Private Sub Command. Button. Surname_Click() Dim e As NWEntry Set e = NWDir 1. Find. Entry(NWDir 1. Login. Name) Text. Box 4. Text = e. Get. Field. Value("Surname") End Sub
