This is a type of validator that you can include on a page. The ID is ID_RegExValidator (defined in IValidator.h), which has a text value of "Microsoft.Wizard.Validation.RegEx."

This validator compares the contents of a text control (one that supports IStaticText) to a regular expression and fails if the text does not match the regular expression.

Alternatively, you can use this validator with a predefined named pattern. To use a regular expression, the XML must contain a setter property called Pattern. If you want to use a named pattern instead, use a setter called NamedPattern set to one of the values in Table 7.

Table 7. Named Pattern Setters

Pattern	Description
Username	Verifies that the text is either of the form domain\user or user@domain
ComputerName	The name must be between 1 and 15 characters long and cannot include a set of characters (such as : and ?)
Workgroup	The name must be between 1 and 15 characters long and cannot contain a set of characters (such as =, +, and ?)
