In the implementation of DefineContextMenu, note how a foreach loop is used to iterate over the items in the View menu. Each item is added to the ctxtMenuView context menu using the MenuItems property of the class. The identical menu index is used for the new menu so that the order of menus in the context menu will match the order used in the View menu. This feature is important, since the foreach loop does not provide any guarantees on the order in which MenuItem objects are presented to the loop. 100

menu item, but its child menu items and all event handlers associated with each menu. Because of our careful construction of the Popup and Click event handlers earlier in the chapter, these handlers work without any changes. It is important to realize that the MenuItem objects within our context menu are not the same as those under the View menu. In particular, if you manually modify an item (such as the menuStretch menu), it will have no effect on the context menu. This may seem a bit strange to programmers used to managing memory in their application, since there are no pointers or other mechanisms required to track these new MenuItem objects. The references to these objects from the context menu are tracked internally as part of the garbage collection system, leaving us to concentrate on our next subject instead of worrying about memory management.

That s it for menus in .NET. In this chapter we showed how both menu bars and context menus can be created, modified, and handled within the .NET Framework by adding these controls to our MyPhotos application. We looked at submenus, and showed how a single event handler can be used by multiple menu objects. The shared event handlers we created supported both our menu bar as well as our context menu. The contents of our context menu were cloned, or copied, based on the contents of the top-level View menu so that the behavior and processing of both constructs were identical. We also examined some C# keywords such as the is, in, and foreach keywords, as well as the bool type. We looked at the Properties window in Visual Studio .NET in more detail, and used this window to add various events to our program. Future chapters will rely on our knowledge of menus and the C# and Visual Studio items we have learned here. The next chapter will take us to the bottom of the application window, where the status bar normally resides.

One resource for menus specifically and .NET in general is the GotDotNet web site at www.gotdotnet.com. This site is currently managed by Microsoft, and bills itself as the .NET Framework Community Website. General information about the .NET Framework can also be found on the Microsoft Developer Network at msdn.microsoft.com. These and other Internet sites with information on .NET are listed in appendix D.

Most applications stuff a lot of information and features into a single window. Most users do not use all of these features, but there is often a core subset that all users would appreciate having at their fingertips. A status bar is a good place for this type data, as it can provide quick feedback related to the current task or cursor position. My word processor, for example, indicates the current page number, total number of pages, column and line position of the cursor, whether the Insert key has been pressed (which I seem to hit constantly while aiming for the Page Down key), and other information I may want to know at a glance. This helps me keep track of how this book is shaping up, when the Insert key has been pressed, and where these words you are reading will appear on the page. Status bars can also contain graphical information such as the status of the printer, whether the application is connected to the Internet, and pretty much anything else you can draw or animate. In this chapter, we will look at status bars in Windows Forms by adding the status bar shown in figure 4.1. As you can see, this status bar contains three areas, called 102
panels. You can place any number of panels on a status bar, or you can use a status bar with no panels and simply display text.
Figure 4.1 Our status bar will include the optional sizing grip graphic at the lower right of the control. A user can click this graphic to resize the form.
