Let s examine the line piece by piece. The first part the numbers and asterisks refers to when the task should be run. From left to right, the fields refer to the following: Minutes, from 0 to 59 Hours, in 24-hour time, so from 0 to 23 Day of the month, from 1 to 31 (assuming the month has that many days) Months, from 1 to 12 Day of the week, either from 0 to 6 (0 is Sunday), or specified as a three-letter abbreviation (mon, tue, wed, and so on) In the example, the task is set to run at the first minute at the twelfth hour (midday) on the fifteenth day of the month. But what do the asterisks stand for They re wildcards, and tell cron that every possible value applies. Because an asterisk appears in the month field, this task will be run every month. As an asterisk appears in the day field, too, the task could run on any day of the week. You might have noticed a logical contradiction here. How can you specify a day if you also specify a date in the month Wouldn t this seriously limit the chances of the task ever running Yes, it would. If you were to specify sat, for example, and put 15 in the date field, the task would run on only the fifteenth of the month if that happened to be a Saturday. This is why the two fields are rarely used in the same crontab entry, and an asterisk appears in one if the other is being used. After the time and date fields comes the command itself: tar. As you learned in the previous chapter, this tar command can be used to back up your personal data (in this example, as long as your username is keir).

public static Object CreateProxy(Type type) { if (_wellKnownTypes==null) InitTypeCache(); WellKnownClientTypeEntry entr = (WellKnownClientTypeEntry) _wellKnownTypes[type]; if (entr == null) { throw new RemotingException("Type not found!"); } return Activator.GetObject(entr.ObjectType,entr.ObjectUrl); } public static void InitTypeCache() { Hashtable types= new Hashtable(); foreach (WellKnownClientTypeEntry entr in RemotingConfiguration.GetRegisteredWellKnownClientTypes()) { if (entr.ObjectType == null) { throw new RemotingException("A configured type could not " + "be found. Please check spelling in your configuration file."); } types.Add (entr.ObjectType,entr); } _wellKnownTypes = types; } } The following is a sample configuration file that can be used with the RemotingHelper to configure the interface IRemoteCustomerManager to use a remote implementation: <configuration> <system.runtime.remoting> <application> <client> <wellknown type="General.IRemoteCustomerManager, General" url="http://localhost:1234/CustomerManager.rem" /> </client> </application> </system.runtime.remoting> </configuration> You have to take care when using configuration files like these because the .NET Framework by default doesn t support the creation of remote references for configured interfaces. This is only possible when using the RemotingHelper class, and someone who reads your code for the first time might not know about this.

Consider the following XAML. There are four text boxes displayed, all bound to the same property in code behind. The difference, however, is that each TextBox change displays the data differently based on the binding s StringFormat extension. The first TextBox shows the raw data, the second formats the data to three decimal places, the third shows the value in scientific notation, and the fourth shows the data as currency. The result is shown in Figure 5-17. <Grid x:Name="LayoutRoot" Background="White"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <TextBox Margin="5" Grid.Row="0" Text="{Binding DecimalValue}" /> <TextBox Margin="5" Grid.Row="1" Text="{Binding DecimalValue, StringFormat='##.###'}" /> <TextBox Margin="5" Grid.Row="2" Text="{Binding DateValue, StringFormat='MMM dd, yyyy'}" /> <TextBox Margin="5" Grid.Row="3" Text="{Binding DecimalValue, StringFormat='c'}" /> </Grid>

In this section, you learned how to use the NavigationContext object to pass data to navigation views using the query string. In the next section, I will discuss Uri Mapping and how it can be used to create user friendly Uri s to your navigation views.

You will now get a chance to check out the settings for the installers and then the actual installation will begin. At the Confirm Installation Settings screen, review the settings you will be using and then click on the Next button. If you are installing the Web Console, .Net will install first, and here you are likely best using the default options. DirectControl will then install. Click Next to run the installation steps. Licensing is always fun. Writing about licensing sometimes seems silly, but it s better than skipping over it. At the Review License Agreement screen, read the license agreement and if you accept it, click on the I agree to these terms radio button. Then, click on the Next button to continue. The User Registration screen needs a username and an organization name, so type those in and then click Next, as shown in Figure 3-14.
