You can concatenate simple regular expressions into complex search criteria to validate against complex patterns, such as any of several words with different endings.

To validate other forms of input, such as query strings, cookies, and HTML control input, you can use the System. The attacker can then supply carefully crafted input that compromises your application by attempting SQL injection, cross-site scripting, and other injection match and validate the text that users enter in cfinput and cftextinput tags.Ordinary characters are combined with special characters to define the match pattern.Since a version of this control hasn't been provided for use in Windows Forms, it makes a great example of a custom control that you can build—a Windows Form Text Box that validates its contents against a regular expression.To create my validating Text Box, I will have to work through a few different steps.You can constrain the input format by defining patterns that the input must match.

Duncan Mackenzie Microsoft Developer Network May 2002 Summary: Covers the basics of inheriting from another control and adding your own properties, methods, and events along with adding your own code; one of a series of Microsoft Windows Forms control development samples to be read in conjunction with associated overview article. This article is the second in a five-article series on developing controls in Microsoft® .

The Cold Fusion server evaluates the variables and functions before the regular expression is evaluated.

For example, you can validate against a value that you generate dynamically from other input data or database values.

The validation succeeds only if the user input matches the pattern.

Regular expressions let you check input text for a wide variety of custom conditions for which the input must follow a specific pattern.

To fix this problem, you implement an activation system where, after registering, I am sent an email with a link I must click.
