Millions of Windows computers have been infected by a new computer worm dubbed “Conficker.” The situation is “not getting better,” but rather is “getting worse,” according to security software vendor F-Secure. In a blog post, F-Secure security researchers report that the number of machines infected by the Downadup worm has skyrocketed from roughly 2.4 million to over 8.9 million in the last four days alone. Downadup is a malicious worm that “uses computer or network resources to make complete copies of itself,” according to F-Secure. And it may also...

In Access, you can limit user entries by forcing users to choose a value from a list control. Office applications use the same functionality in built-in drop-down lists. For instance, the Highlight and Font Color controls on most Formatting toolbars use this flexible tool. Simply click the small triangle to the right of the icon to display a list of choices.

Fortunately, once you know the feature exists, it’s easy to implement. You need only...
