I list testing manager as a specialization, rather than a promotion up from tester, because it usually isn t available as a promotion from tester Most often, testers go on to become assistant and associate producers first Testers don t have enough administrative experience to move directly to testing manager Once they have gained the necessary management skills in production, then they can move sideways to be a testing manager Testing managers do a little testing themselves to help out during crunch time, but their real job consists of four key tasks: Defining the test plan for a game This is an enormous and extremely intricate problem that requires a thorough understanding of how software works and how it can be proven to work correctly The testing manager consults with the designers and programmers to document every function and aspect of the game that is subject to observational analysis (stepping through the code in a debugger doesn t count!), then builds a plan for actually performing that analysis

2 The Component class is the base implementation of the IComponent interface A component is an object that can exist within a container, and allows cleanup of nonmemory resources via the Dispose method This class supports the IDisposable interface as well the IComponent interface We ll cover interfaces in chapter 5, so don t get caught up in the terminology here Since graphical controls exist within a Form window or other container control, all Windows Forms controls ultimately derive from this class 313 DERIVED CLASSES The NET Framework derives three menu classes from the abstract Menu to support menu bars, context menus, and the menu items they contain The MainMenu class represents a main menu for an application MainMenu objects contain a collection of MenuItem objects to display in the menu bar The ContextMenu class represents a context menu associated with a specific control.

ContextMenu objects also contain a collection of MenuItem objects to display when this menu pops up The MenuItem class represents a menu item that appears within another menu An instance of a MenuItem can contain a collection of MenuItem objects to appear as the submenu of this item While an unrestricted number of submenus are permitted, it is a good idea to keep such menu hierarchies limited to no more than two or three levels Too many submenu levels can be confusing for users and are best avoided when possible We will discuss each class separately, beginning with the MainMenu class..

It is worth noting that object, as a class, is a reference type, whereas types such as int and char are value types. When a value type is used as an object instance, the value type is converted to a reference type via a process called boxing. This process is totally hidden from the programmer, but does have performance implications. See appendix A for a discussion of this concept in more detail. The details of marshalling is totally hidden for most Windows Forms applications, so you do not really need to know any of this. Hopefully, you find it somewhat interesting if not useful.

software license rather than investigating other potential tools could easily become one of the most expensive mistakes of embracing BIM technology The importance of a basic understanding of the concepts and applications of the BIM processes, to make intelligent choices among the available products, cannot be overstated Once an understanding for BIM has been developed, answers to the following questions will help in choosing a particular product:
