You ll find that productVariable1.Price is set to 25.99. Of course, this only makes sense because productVariable1 and productVariable2 are two variables that point to the same in-memory object. If you really do want to copy an object (not a reference), you need to create a new object, and then initialize its information to match the first object. Some objects provide a Clone() method that allows you to easily copy the object. One example is the DataSet, which is used to store information from a database.

A similar distinction between reference types and value types appears when you compare two variables. When you compare value types (such as integers), you re comparing the contents. If integerA = integerB Then ' This is true as long as the integers have the same content. End If When you compare reference type variables, you re actually testing whether they re the same instance. In other words, you re testing whether the references are pointing to the same object in memory, not if their contents match. VB emphasizes this difference by forcing you to use the Is keyword to compare reference types. Using the equals (=) sign will generate a compile-time error. If productVariable1 Is productVariable2 Then ' This is True if both productVariable1 and productVariable2 ' point to the same thing. ' This is False if they are separate objects, even if they have ' identical content. End If

You can use two types of method parameters. The standard type is pass-by-value. When you use pass-by-value parameters, the method receives a copy of the parameter data. That means that if the method modifies the parameter, this change won t affect the calling code. By default, all parameters are pass-by-value. (Visual Studio also inserts the ByVal keyword automatically to make that fact explicit.) The second type of parameter is pass-by-reference. With pass-by-reference, the method accesses the parameter value directly. If a method changes the value of a pass-by-reference parameter, the original variable is also modified.
