Conversely, when Windows Forms needs to know the property value of ApplyAuthorization for a particular control, it calls GetApplyAuthorization(). The value for that control is retrieved from the Dictionary object and returned. If the control can t be found in the Dictionary, then false is returned, since that control is obviously not being extended. The end result here is that the ReadWriteAuthorization control maintains a list of all the controls it extends, along with their ApplyAuthorization property values. In short, it knows about all the controls it will affect, and whether it should be affecting them or not.

This model is most frequently used when there is no security infrastructure that can be used by both parties during the authentication process. The diagram in Figure 7-1 shows how the client, service, and identity store interact in order to validate a client request.

I happen to write code for both Java and .NET. A discussion of both platforms is beyond the scope of this book, but I mention Java because the Java platform implements the ToString method, whereas on .NET ToString exists, but is rarely implemented. The collection classes are the simplest illustration of where ToString should have been implemented in .NET. Calling a collection s ToString implementation in Java iterates and outputs the various elements. However, that doesn t happen in .NET, and when writing code using test-driven development (TDD), ToString makes it possible to figure out what the state of the type instance is. Consider the following simple example of implementing the ToString type: class MyClass { private string _buffer; public override string ToString() { return "Buffer (" + _buffer + ")"; } } The class MyClass has a data member _buffer, which should be represented when the ToString method is called. In the implementation of ToString, return is a descriptive buffer. The format of the return buffer is dependent on the need. The format could be an XML buffer, or something else. Regardless of the format, a type should always implement the ToString method.
