Use
this dialog box to define a validation pattern for validating user
input (date, time, numerical, and textual data). The pattern must
match the syntax of the user input. Only this tab is available with
barcodes, drop-down list, and list box; the Display, Edit, and Data
tabs are not available.
To display this dialog box, select the object you want to create
a pattern for and, in the Object palette, click the Value tab, click
Validation Patterns, and click the Validation tab. The options on
this tab are the same as the options on the Display tab. For information
about the options available, see Display (Patterns dialog box).
Note: This option is not available when the Type option is set to
Protected, Calculated - Read Only or Read Only.
