The big change is that, instead of calling the DefineWord() method directly here, we re creating a new SearchPage and passing the word in the constructor. Then, we call the Navigate method on the NavigationService, but instead of passing a URI, we pass the page to which we want to navigate. One problem is that SearchPage doesn t have a constructor that takes a search word. We can add that easily enough (Listing 16.4).

public SearchPage(string word) { InitializeComponent(); searchText.Text = word; DefineWord(word); Title = "Search - " + word; }

The constructor has to call InitializeComponent() to set up the page. We then set the text in the searchText TextBox. We don t have to do this, but it would look odd if the word disappeared after the search is finished. Next we call DefineWord(). This method will do the lookup and populate the document with the definition. Finally, we set the Title of the page. The Title will be Figure 16.9 Each used within the search history to identify our location. This is one search now shows up in of several places where the navigation service will look for text for the search history. the search history; it s the easiest to set for the moment. Now if we run and do a couple of different searches, the back arrow will become enabled and, if we hit the search history button, we ll see all our searches (figure 16.9).

Not too shabby. If you hit the back button, you will see the previous pages with their definitions. This brings up an interesting question, though: Is the application holding on to all the pages, or is it reloading them each time The answer could have a major impact on performance and memory usage. A simple change to our application will make it easy to tell we ll add a timestamp to our results. If the data is being queried again, then we ll get a new timestamp; otherwise, it will hold the old value. To add a timestamp, we add the following code in the DefineWord() method, between the title paragraph and the definition paragraph:

In addition to the above-mentioned fiber-optic converter, it should be apparent from reading the chapter covering fiber in the LAN that a

Figure 16.10 When we go back to the page, we can see that the timestamp hasn t changed, so the page hasn t been reloaded.

second type of converter exists Thus, in the remainder of this chapter we will compare and contrast the use of the two types of fiber-optic converters The converter described in this section represents an optical mode converter As discussed in this section, this type of converter converts single-mode fiber to multimode and vice versa, and the rationale for its use is its ability to drive the optical signal a sufficient distance beyond the direct use of a particular medium If we remember our discussion of fiber-optic converters in 5, we noted that they converted an electrical signal into an optical signal However, we also noted that their primary role was as a mechanism to extend transmission distance Thus, the primary difference between the optical mode converter discussed in this section and the media converter discussed in 5 concerns their interfaces The mode converter has dual optical interfaces, while the media converter has one electrical interface and one optical interface However, both types of communications devices are similar in that the primary rationale for their use is to extend transmission distance
