r Where computer is the IP address, host name, or DNS name of the remote computer you want the MAC address for. Finally, you can obtain the MAC address of any current DHCP client by looking at the current DHCP lease for the client the MAC address is shown in the Unique ID column.

Office Spreadsheet Web Parts can contain formulas as simple as the sum of two cells, and as complex as you want to make them. You can enter formulas directly into cells by entering an = sign and then constructing the formula just as you would in Excel. There s no formula bar in the web part, so to see the formula in a cell, double-click it or open the Commands and Options dialog box and click the Formula tab. This shows the formula and the results of the formula in the active cell. Except for SUM, which is available by clicking the AutoSum button on the toolbar, there is no assistance, such as the Insert Function dialog box in Excel, for constructing formulas with functions. You must enter the formula that includes the function by typing it in the proper syntax. However, there s an extensive help file that lists all the available functions, their proper syntax, and examples. Click the Help button on the toolbar, then double-click Working with Functions to access the list of available functions by category. You can use the Formula tab of the Commands and Options dialog box to name cells for easier reference in formulas. To name a cell or range of cells, select the cell or range you want to name, then enter a name in the Name text box on the Formula tab. Use these guidelines to name cells:

Microsoft Dynamics CRM uses icons in the user interface to represent each of the default system entities. These icons appear in the navigation pane, views, and on the entity s form. In addition to improving the visual aesthetics, these entity icons help users navigate the system by providing graphical indicators about each type of record. By default, Microsoft Dynamics CRM assigns the same icon to all custom entities.

If you looked at the ASPX source code generated by Visual Studio as you placed controls on the page, you probably noticed the page became littered with tags, such as server-side control tags to support text boxes and selection controls . In addition, each validator control placed on the page corresponds to a separate tag . Validators are server-side controls, too . They render standard browser-interpretable code similar to regular server-side controls . ASP .NET validator controls support client-side validation by including references to JavaScript utilities that are included with the HTML sent to the browser . The file contains the client-side validation functions necessary to support client-side validation . When the validation controls render to the browser, they add to the rendered HTML span elements with custom attributes . The validation handlers are hooked up when the HTML document is loaded in the browser . Because client-side validation requires JavaScript support in the client, clients without JavaScript support must rely on server-side validation . If you want, you can disable the clientside script for each control by setting the EnableClientScript property on the validator to false .

1. The SALGRADES table has two columns to indicate salary ranges: LOWERLIMIT and UPPERLIMIT. Define your own SALRANGE_T type, based on a varray of two NUMBER(6,2) values, and use it to create an alternative SALGRADES2 table. Solution 12-1. SQL> create or replace type salrange_t 2 as varray(2) of number(6,2); 3 / Type created. SQL> 2 3 4 5 6 7 8 create table salgrades2 ( grade number(2) , salrange , bonus ) ; constraint S2_PK primary key salrange_t constraint S2_RANGE_NN not null NUMBER(6,2) constraint S2_BONUS_NN not null

However, you can get more interesting details about the problem by using the Windows Action Center applet . To start the Action Center, click on the flag icon in the system tray, select Open Action Center, expand the Maintenance box, and then select the View reliability history link . From here, you can see the applications that have terminated due to an unhandled exception in the bottom pane, as shown in Figure 20-2 .

The practice tests on this book s companion CD offer many options. For example, you can test yourself on just the lesson review questions in this chapter, or you can test yourself on all the 70-515 certification exam objectives. You can set up the test so it closely simulates the experience of taking a certification exam, or you can set it up in study mode so you can look at the correct answers and explanations after you answer each question.

Before starting to write the code for the shopping cart, let s take a closer look at what you re going to do. First, note that you won t have any user personalization features at this stage of the site. It doesn t matter who buys your products at this point, you just want to know what products were sold and when. When you add user customization features in the later chapters, your task will be fairly simple: when the visitor authenticates, the visitor s temporary (anonymous) shopping cart will be associated with the visitor s account. Because you work with temporary shopping carts, even after implementing the customer account system, the visitor isn t required to supply additional information (log in) earlier than necessary. Probably the best way to store shopping cart information is to generate a unique cart ID for each shopping cart and save it on the visitor s computer as a cookie. When the visitor clicks the Add to Cart button, the server first verifies whether the cookie exists on the client computer. If it does, the specified product is added to the existing cart. Otherwise, the server generates another cart ID, saves it to the client s cookie, and then adds the product to the newly generated shopping cart. In the previous chapter, you created the componentized templates by starting with the presentation layer components. However, this strategy doesn t work here because now you need to do a bit more design work beforehand, so we ll take the more common approach and start with the database tier.

In Windows Vista, you can create custom versions of Autoexec.nt and Config.nt for specific applications. To associate your custom configuration files with a specific application, copy the default files to a separate location and edit them as needed. Next, open the properties dialog box for the MS-DOS program, click the Advanced button on the Program tab, and then enter the correct locations as shown below. (Note that this dialog box includes a Compatible Timer Hardware Emulation check box. This option imposes a performance penalty, so you should select it only if your application won t run with the box cleared.)

Two sets of protocol implementation classes are available in the .NET Framework. The HttpWebRequest and HttpWebResponse classes are responsible for the http and https URI schemes, while FileWebRequest and FileWebResponse are responsible for the file scheme. These protocol-specific classes aren't available for direct instantiation. The static Create and instance GetResponse methods in the WebRequest class always return one of the abstract base classes. If the programmer requires more specific access, the types returned from these methods can be cast to the appropriate protocol-handler class.
