dialog box, as shown in Figure 2-19. Make sure that you enable the Structure check box. If you
also mark the Windows check box, you can’t move or resize the window.

In some cases, you may want to limit access to a workbook to only those who know the password.
To save a workbook file with a password, choose File➜Info➜Protect Workbook➜Encrypt With
Password to display the Encrypt Document dialog box (see Figure 2-20). In this dialog box, you
can specify a password that’s required to open the workbook.

the VBE (Alt+F11) and select your project in the Projects window. Then choose Tools➜ xxxx
Properties (where xxxx corresponds to your Project name) to display the Project Properties
dialog box.
