Securing Your VBA Script from Prying Eyes
In Chapter 2 we discussed Kiosk mode. By us ing Ki osk mode, you have put
in place some security. Students will not be able to
jump to any slide or skip a
slide us ing the keyboard. However, you might put something in your VBA code
that you don’t want them to see. For ex ample,
if you are writing a quiz, your
VBA code will in clude the answers so it can tell the students when they got the
right and wrong answers. It is very easy to pro tect your VBA code with a pass-
word. While in the VBA Ed itor (where you
edit the VBA code, not where you
edit the PowerPoint slides), se lect “VBAProject Prop erties . . . ” from the Tools
menu and click on the Protection tab (see Figure 4.6).
Figure 4.6. Set ting a Password
Check the box that is labeled “Lock
pro ject for viewing,” type a password
in the password box, and type the same password in the “Con firm pass word”
box. Now, when ever you want to
view or edit the VBA code, you will be asked
to type this password. Don’t for get it, or you will not
be able to access your own
project.
Note that in newer ver sions of PowerPoint (beginning with 2002), you can
set a password to access your file. If you choose to use this,
be ware of two
things: (1) Any one viewing your presentation will need the password, and (2)
anyone us ing a version of PowerPoint earlier than 2002 will not be able to view
your presentation.
