Click the <add method> entry under the Methods node in the Class Details window and enter ValidateUser. 3. Enter int (Integer in VB) for the Type. 4. Click the ellipsis in the Summary column. 5. Enter Validates that the user is in the system for the Summary. 6. Enter 0 if the user is not found, otherwise the ID of the user for the Returns value. 7. Expand the ValidateUser node to expose the method s parameters. 8. Click the <add parameter> entry under the ValidateUser method (or press the ( key on the keyboard) and enter userName.

Be very careful when using the assignment operator = and the equal to operator ==. If you mistakenly use = for the comparison operator, the left value is overwritten by the right, and if the left value is nonzero, then the comparison will have a true result. This is unlikely to be what you want.

Windows CardSpace is a specialized identity metasystem that helps you manage multiple identities. Let s take an everyday example. You use your driver s license to prove you are a valid driver on the road. How do you prove this to a suspecting police officer who inquires about it You show them a valid driver s license card. Likewise, you use a card to prove to an ATM that you have the correct credentials to withdraw money. You use different physical cards to accommodate different situations, and if you have a lot of cards, you need a mechanism to manage them. A common practice is to store all the cards in a wallet. In this way, the wallet becomes your identity metasystem in everyday life. You can use the same concept in distributed computing. The .NET Passport system provides an email address and password to validate you. This is similar to the bank providing a card to withdraw cash.

Logical operators are similar to comparison operators except that they compare Boolean values instead of expressions. The three logical operators are shown in Table 2-13.

NOT: If the operand was true, then false is evaluated or vice versa. AND: If both operands are true, then evaluate to true; otherwise, evaluate to false. OR: If either or both operands are true, then evaluate to true; otherwise, evaluate to false.

Similarly, your employees will give the administration digital signature that proves they are legitimate employees of the company. How do you store all these identities and extract them on demand to facilitate your needs The answer lies in Windows CardSpace. A card is a digitally signed entity that illustrates a user s claims to a system. In general, two types of cards exist. The first one is a personal card, which a user can issue to herself. This is similar to picking an e-mail address and a password for a Passport account. The second type is the provider card, which is provided by a trusted third party. This is similar to a bank card that is given to you by the bank.
