The eight color options in this dialog box have their most pronounced effect on window frames. You ll also notice some effect on your taskbar and Start menu, particularly with the brighter colors (red and orange, for example) and at higher Color Intensity levels. If none of the eight choices meets your needs exactly, you can click Show Color Mixer and dial in your own blend of Hue, Saturation, and Brightness:

QStringListModel model; QModelIndex index = model->createIndex(0); QString datum = model->data(index, Qt::DisplayRole).toString();

Figure 13-2: The ASP.NET architecture to process page and Web service requests. The connection between the IIS process (the executable named inetinfo.exe) and the HTTP pipeline (the worker executable named aspnet_wp.exe) is established through a named pipe that is, a Win32 mechanism for transferring data over a network. As you'd expect, a named pipe works just like a pipe: you enter data in one end, and the same data comes out at the other end. Pipes can be established both locally to connect processes and between remote machines. After the ASP.NET worker process receives a request, it routes that request through the .NET Framework HTTP pipeline. The entry point of the pipeline is the HttpRuntime class. This class is responsible for packaging the HTTP context for the request, which is nothing more than familiar Active Server Pages (ASP) objects such as Request, Response, Server, and the like. These objects are packed into an instance of the HttpContext class, and then a .NET Framework application is started. The WebService Class In the .NET Framework, a Web service is an ordinary class with public and protected methods. The Web service class is normally placed in a source file that is saved with an .asmx extension. Web service files must contain the @ WebService directive that informs the ASP.NET run time about the nature of the file, the language in use throughout, and the main class that implements the service, as shown here: <%@ WebService Language="C#" Class="MyWebServiceClass" %> The Language attribute can be set to C#, VB, or JS. The main class must match the name declared in the Class attribute and must be public, as shown here: 457

It is always more accurate to make geospatial measurements using the GEOGRAPHY type than the GEOMETRY type . This is especially true as distances become greater . Still, calculations on projected coordinates using the GEOMETRY type can be quite accurate if the projection is chosen carefully .

start thinking about class inheritance hierarchies and how to properly override Equals . Here is how to properly implement an Equals method internally: 1. If the obj argument is null, return false because the current object identified by this is obviously not null when the nonstatic Equals method is called . 2. If the this and obj arguments refer to the same object, return true . This step can improve performance when comparing objects with many fields . 3. If the this and obj arguments refer to objects of different types, return false . Obviously, checking if a String object is equal to a FileStream object should result in a false result . 4. For each instance field defined by the type, compare the value in the this object with the value in the obj object . If any fields are not equal, return false . 5. Call the base class s Equals method so it can compare any fields defined by it . If the base class s Equals method returns false, return false; otherwise, return true . So Microsoft should have implemented Object s Equals like this:

This example shows that you should never lose hope when searching for an efficient solution. If you invest the time and think outside the box, in most cases you'll find a solution.

With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain IP addresses and related configuration parameters each time they start and join your network. DHCP servers provide this configuration in the form of an address lease offer to requesting clients. One main advantage of using DHCP is that DHCP servers greatly reduce the time required to configure and reconfigure computers on your network. DHCP simplifies administration not only by supplying clients with IP addresses, but also (optionally) with the addresses of the default gateway, DNS servers, WINS servers, and other serv ers useful to the client. Another advantage of DHCP is that by assigning IP addresses automatically, it allows you to avoid configuration errors resulting from entering IP address information manually at every host. For example, DHCP helps prevent address conflicts caused when the same IP address is mistakenly assigned to two hosts.

By default, on a computer joined to a domain, users must press Ctrl+Alt+Delete before the logon screen appears. This requirement can be removed from domain computers or added to others, as described below. The Welcome screen for a workgroup or standalone computer shows an icon for each account on the computer, as shown in Figure 11-8. By contrast, after pressing Ctrl+Alt+Delete, a domain user sees only one user account, along with a Switch User button that enables you to log on using an account other than the one shown. (This is the same screen that a workgroup user with a passwordprotected account sees after clicking his or her account name.)

Registered Front-End Users When registered front-end users are given modification privileges, they can access the WYSIWYG editor to post or edit articles. The four subgroups that are held under the registered front-end users category have varying submission capabilities. The four types of front-end users are as follows: Registered: Simple registered users have the ability to read restricted content (if available on the site). They have no capabilities to submit new content articles, although they may submit web links. Author: Members of the author group can post and modify their own articles. They can even determine when the article will be published (limited by the administrator s ability to have a moderator set up who must clear any posted content before it appears). Editor: Like an author, a user in the editor group can post and modify their content. An editor also has the ability to edit other contributors content. Publisher: A user with publisher status can perform any operation available to an editor, but may also publish or unpublish content on the site. If the user account was created through the front-end Joomla interface (rather than by an administrator or super-administrator) by the user filling out a registration form, Joomla can be set to send a confirmation e-mail to the user to ensure that the e-mail address is valid. Joomla handles all of this work, and this feature is enabled by default.
