Because the Binding class is an abstract one, this one constructor is not the only one implemented in the bindings that are provided with WCF. In fact, each of the specialized binding classes has at least one constructor that takes additional parameters. The following sections discuss the constructors for each binding class.

You can also use regular expressions to match repeated characters. The * symbol matches the preceding character zero or more times. For example, to*n matches ton , tooon , or tn . The + symbol works similarly, but it must match one or more times. For example, to+n matches ton or tooon , but not tn . To match a specific number of repeated characters, use {n} where n is a digit. For example, to{3}n matches tooon but not ton or tn . To match a range of repeated characters, use {min,max} . For example, to{1,3}n matches ton or tooon but not tn or toooon . To specify only a minimum, leave the second number blank. For example, to{3,}n requires three or more consecutive o characters. To make a character optional, use the symbol. For example, to n matches ton or tn , but not tooon . To match any single character, use . . For example, to.n matches totn or tojn but not ton or tn . To match one of several characters, use brackets. For example, to[ro]n would match toon or torn but not ton or toron . You can also match a range of characters. For example, to[o-r]n matches toon , topn , toqn , or torn but would not match toan or toyn . Table 3-3 summarizes the regular expression characters used to match multiple characters or a range of characters.

In the following description of the syntax, notice the differences between the [bit registry section] and [add registry section] sections. The parameter value is not optional. Also, the parameters mask and byte replace the value data. The parameter mask is 8 bits long and indicates which bit you want to enable or disable. The parameter byte indicates which byte in the binary value you want to modify. This indicates bytes left to right starting from 0. This is straightforward when working with REG_BINARY values but less so when working with REG_DWORD values. As discussed in 1, "Learning the Basics," Windows XP stores REG_DWORD values in the registry in reverse byte order (little endian architecture). To be sure, test your INF files carefully to make sure you're masking the bits you think you're masking. Figure 9 1 shows the relationship between value, mask, and byte. The value to which I'm applying the mask is a REG_DWORD value stored in the registry in reverse byte notation: 0x0180C000. Set the mask in byte 0, and the result is 0x0180C080. Clear the mask in byte 1, and the result is 0x0140C080.

In the following case scenarios, you will apply what you ve learned in this chapter. You can find answers to these questions in the Answers section at the end of this book.

Notice that the only portions of the statement that are required are the SELECT and FROM clauses. The simplest SELECT statement would look something like the following:

CAS permissions can never override a user s operating system permissions. An assembly s effective permissions are the intersection of the permissions granted to the assembly by CAS and to the user by the operating system. The .NET Framework Configuration tool is a graphical tool to configure any aspect of CAS. To use the tool, launch the Microsoft .NET Framework Configuration from the Administrative Tools group. The Code Access Security Policy tool, Caspol, is a command-line tool with a large number of options for controlling almost every aspect of CAS behavior. To use Caspol, call it from the directory the .NET Framework is installed into.

In all modes, the user interface you see when taking the test is essentially the same, but depending on the mode, different options will be enabled or disabled. After you click OK, your practice test starts.
