load them into an MDI application. To make them available, compile them as class libraries, and then add references to them in the configuration file. Dynamically loading other types of classes This technique can be used in addition to forms for other types of classes. However, the situation is relatively complex. In the previous example, the System.Windows.Forms.Form class interface was able to be bound

configuration data. A reference to a type is saved in Typetoload. Reflection Classes and Activator classes use their CreateInstance methods to create instances of a type. (CreateInstance is similar to CreateObject in Visual Basic 6.0.) However, the instance must be a type object because the type is to be loaded dyn

In order to resolve this situation, if Memoizer finds that the calculation was canceled or detected with RuntimeException, the future will be removed. Memoizer also does not address cache overdue issues, but can be resolved by using subclasses of Futuretask, specifying a time-out for each result in subclasses, and periodically scanning for overdue elements in the cache.
