The same is true when you use the FontDialog, PageSetupDialog, and PrintPreviewDialog that are designed to work with the older Windows Forms printing model In fact, the only Windows Forms dialog box that s of any use and that doesn t have a WPF equivalent in the MicrosoftWin32 namespace is FolderBrowserDialog, which lets the user pick a folder More useful Windows Forms components include the SoundPlayer, which you can use as a lightweight equivalent to WPF s MediaPlayer and MediaElement; the BackgroundWorker (described in 31), which you can use to manage an asynchronous task safely; and the NotifyIcon (described next), which allows you to show a system tray icon The only disadvantage to using the NotifyIcon in a WPF window is that there s no design-time support It s up to you to create the NotifyIcon by hand, attach event handlers, and so on.

Once you supply an icon using the Icon property and set Visible to true, your icon will appear in the system tray (shown in Figure 30-1) When your application ends, you should call Dispose() on the NotifyIcon to remove it from the system tray immediately..

Figure 30-1. A system tray icon The NotifyIcon does use some Windows Forms specific bits. For example, it uses a Windows Forms context menu, which is an instance of the System.Windows.Forms.ContextMenuStrip class. Thus, even if you re using the NotifyIcon with a WPF application, you need to define its context menu using the Windows Forms model. Creating all the objects for a menu in code and attaching event handlers is more than a little tedious. Fortunately, there s a simpler solution when building a WPF application that uses the NotifyIcon you can create a component class. A component class is a custom class that derives from System.ComponentModel.Component. It provides two features that ordinary classes lack: support for deterministically releasing resources (when its Dispose() method is called) and design-time support in Visual Studio.

Every custom component gets a design surface (technically known as the component tray) where you can drag and configure other classes that implement IComponent, including Windows Forms. In other words, you can use the component tray to build and configure a NotifyIcon, complete with a context menu and event handlers. Here s what you need to do to build a custom component that wraps an instance of the NotifyIcon and includes a context menu: 1. 2. Open or create a new WPF project. Right-click the project name in the Solution Explorer and choose Add New Item. Pick the Component Class template, supply a name for your custom component class, and click Add. Drop a NotifyIcon onto the design surface of your component. (You ll find the NotifyIcon in the Common Controls section of the Toolbox.) At this point, Visual Studio adds the reference you need to the System.Windows.Forms.dll assembly. However, it won t add a reference to the System.Drawing.dll namespace, which has many core Windows Forms types. You must add a reference to System.Drawing.dll manually. Drop a ContextMenuStrip onto the design surface of your component (from the Menus & Toolbars section of the Toolbox). This will represent the context menu for your NotifyIcon. Figure 30-2 shows both ingredients in Visual Studio.

Summary

3. 4.

Select the NotifyIcon and configure it using the Properties window. You ll want to set the following properties: Text (the tooltip text that appears when you hover over the NotifyIcon), Icon (the icon that appears in the system tray), and ContextMenuStrip (the ContextMenuStrip you added in the previous step). To build the context menu, right-click the ContextMenuStrip and choose Edit Items. You ll see a collection editor that you can use to add the menu items (which you should place after the root menu item). Give them easily recognizable names because you ll need to connect the event handlers yourself. To see your component class code, right-click the component in the Solution Explorer and choose View Code. (Don t open the .Designer.cs code file. This file contains the code that Visual Studio generates automatically, which is combined with the rest of the component code using partial classes.) Add the code that connects your menu s event handlers. Here s an example that adds the event handler for two menu commands a Close button and a Show Window button:
