Check boxes & Option buttons

These two controls are used when the user must choose from a list of options. The difference between the two is that with Check boxes he can select several at one time but, with Option buttons, he must select only one among several.

The example below illustrates the use of Check boxes and Option buttons. To capture the information entered by means of these controls, you must test the property: Value. In a Check box, Value = 1 if box is checked and = 0 if not. In an Option button, Value = True if selected and = False if not.

The code, although somewhat long, is not very complicated. Most of the time, processing consists of checking the content of .Value. It is fairly standard procedure, especially with Option buttons, to ensure that at least one button has been selected and to display an error message if it has not.
