Explain the differences between a value type and a reference type. Modify the way in which arguments are passed as method parameters by using the ref and out keywords. Box a value by initializing or assigning a variable of type object. Unbox a value by casting the object reference that refers to the boxed value. In 7, Creating and Managing Classes and Objects, you learned how to declare your own classes and how to create objects by using the new keyword. You also saw how to initialize an object by using a constructor. In this chapter, you will learn about how the characteristics of the primitive types, such as int, double, and char, differ from the characteristics of class types.

The Button class automatically raises the Click event when you click the button on-screen. (How this actually happens is beyond the scope of this book.) This arrangement makes it easy to create a delegate for a chosen method and attach that delegate to the required event. The following example shows the code for a WPF form that contains a button called okay and the code to connect the Click event of the okay button to the okayClick method:

Everything is an object under Visual Basic .NET. One consequence of this arrangement is that when you assign a variable to another variable, you get two variables pointing to the same object, rather than two distinct copies of the data (unless you re working with value types instead of reference types). Typically, you can get a copy of the data by invoking a special method that the class exposes. In the .NET world, a class should implement the ICloneable interface and expose its only method, Clone, to let the outside world know that it can create a copy of its instances. Several objects in the framework implement this interface, including Array, ArrayList, BitArray, Font, Icon, Queue, and Stack. Most of the time, implementing the ICloneable interface is straightforward:

Part VI:

The estimate for the operator is taken by looking at the histogram, counting the number of sampled rows matching the criteria (in this case, we have 10 histogram steps with 200 equal rows for values that match the lter condition). Then, the number of qualifying rows (2,000) is normalized against the number of rows sampled when the histogram was created (10,000) to create the selectivity for the operator (0.2). This is then multiplied by the current number of rows in the table (10,000) to get the estimated query output cardinality. The cardinality estimation process is continued for any other lter conditions and the results are usually just multiplied to estimate the total selectivity for each condition. One other interesting aspect of the histogram is RANGE_ROWS, DISTINCT_RANGE_ROWS, and AVG_RANGE_ROWS. Because histograms are limited to 200 steps, some values being queried may not be represented in the histogram steps. These values are represented in the RANGE values, and they are counts of rows between the step values. For query conditions that do not match one of the equal (EQ) rows in the histogram, values in the range are assumed to be uniformly distributed over the domain between the two bounding histogram steps. The fraction is determined from this assumption and used to generate the selectivity, as in the previous examples. Although most operators work using a mechanism similar to Filter, some other operators need additional mechanisms to make good cardinality estimates. For example, GROUP BY actually doesn t try to determine which slices of a histogram should be used to estimate the selectivity of the operator. Instead, it needs to determine the number of unique values over a

You can use report parameters to make reports more flexible in a number of ways. A report parameter can be used alone to calculate values in the report. Such values can be either displayed as content in the report or used to change properties that affect the behavior and appearance of a report. For example, instead of using a fixed value to control conditional formatting in a report, as you did in 5, Working with Expressions, you can add a report

The requestType argument is a string that evaluates to GET or POST the HTTP verb of the request. The last two arguments represent the raw URL of the request and the physical path behind it. The ReleaseHandler method is a mandatory override for any class that implements IHttpHandlerFactory; in most cases, it will just have an empty body. The following listing shows a sample HTTP handler factory that returns different handlers based on the HTTP verb (GET or POST) used for the request:
