The bug database The testing manager (your boss) will have set up a database for recording bugs in the product you re testing When you find a bug, you create a new entry for it and enter the details You won t have to know anything about database programming or management to use it It s seldom any more complicated than filling in a form or using a search facility on a web site The most commonly used database programs are FileMaker Pro and Microsoft Access, if you want to get some experience working with them ahead of time A VCR It s very hard to remember exactly what you were doing when a bug occurs, especially if the program crashes and the screen goes blank Most testing nowadays is done with a VCR attached to the video output of the machine so you can record what you re doing as you go In addition to allowing you to retrace your steps, the VCR enables you to show the bug to one of the programmers if it s an intermittent problem that is not easily reproducible

311 THE MENU CLASS All menus in NET derive from the Menu class This class provides the core capabilities required by all menus, such as access to the parent menu, if any, and the collection of submenu items for the menu The Menu class, summarized in NET table 31, is abstract, meaning you cannot create an instance of it You will note in NET table 31 that the MenuMenuItems property contains a collection of MenuItem objects This is an odd notion for object-oriented environments, since Menu is the base class of MenuItem, yet it uses this derived class as part of its definition Such an arrangement is not disallowed, and is useful in situations like this when an object should contain instances of its own type.

THE MENU CLASS HIERARCHY Before we plunge into specific types and examples of menus, it is useful to step back and consider the class hierarchy for the Menu class A class hierarchy is the set of classes from which a particular class is derived, and gives some indication of the purpose and capabilities behind the specific class The class hierarchy for the Menu class is also interesting because it is all or part of the class hierarchy for most Windows Forms controls As you can see from figure 33, there are three classes beside Menu in this hierarchy..

The Menu class derives from the Component class, which derives from the MarshalByRefObject class, which derives from the Object class. All classes in C#,

Testing games is a fairly uniform activity, and the nature of the work doesn t change that much from day to day But there are a few specializations in the field

The Menu class is the base class for all menus in the .NET Framework. This abstract class is part of the System.Windows.Forms namespace, and inherits from the System.ComponentModel.Component class. Handle Gets the window handle for the menu. Used as a back door to special operations not supported by the framework. Gets whether this menu contains any MenuItem objects. Gets the MenuItem, if any, that will display the list of MDI child forms currently open in the application. Gets the MenuItemCollection object that holds the list of MenuItem objects attached to this menu, or null if no items are attached. Returns the ContextMenu object that contains this menu, or null. Returns the MainMenu object that contains this menu, or null. Merges a given Menu object into the current menu. Occurs when the component is disposed, such as when the Dispose method is called for the component.

difficult to learn about a product and research its specifications; most potential buyers simply want the assurance that it will work, and they will try to just begin using it This approach could easily lead to unanticipated problems, particularly in the area of BIM tools With its relatively short history and complexity, building information modeling has created many unrealistic promises and expectations, on the parts of both the users and the developers of the software tools Expecting to save money by upgrading an existing

Disposed (inherited from Component)

even internal types such as int and char, implicitly derive from the object class1 In the NET Framework, this class is equivalent to the Object class We will discuss this class in more detail in chapter 5 The MarshalByRefObject class is an object that must be marshaled by reference Marshaling is a method of passing an item from one context so that it can be understood in another context A typical use for marshaling is in remote procedure calls between two different machines, where each parameter of a function call must be converted into a common format (that is, marshaled) on the sending machine so that it may be interpreted on the receiving machine In the NET world, Windows controls are MarshalByRefObject objects since they are only valid in the process that creates them, and can be used outside this process only by reference.
