Flash-db.com provides several hosted web services free of charge. One of these services is the excellent Company Information Web service. This provides basic and extended stock price information, as well as the name of the company associated with a stock ticker. Accessing this from a Visual Studio 2005 application is straightforward. The WSDL for the web service is hosted at the following location: http://www.flash-db.com/services/ws/companyInfo.wsdl To create a proxy to this, right-click your project in Solution Explorer, and select Add Web Reference (see Figure 11-3).

This will present a dialog box in which you specify the WSDL of the service you are referencing (see Figure 11-4). When you enter a valid WSDL here, the description pane will update with the supported functions on the web service, as well as the services that are available to this WSDL (multiple services can be published to a single WSDL). In the Web Reference Name field, you should enter a friendly name, because this is the name that will be generated for the proxy that talks to the web service on your behalf. The Company Information web service is used in the application to present the name of the company as well as the current price information (see Figure 11-5). Additionally, when the button to the right of the current price is clicked, some extended stock price information appears. This demonstrates a partial update of the page. When running it, you will see that this segment updates without incurring a full-page refresh and associated blink. It also provides a status that the application is loading while the asynchronous update is taking place (see Figure 11-6).

Figure 11-7. Showing the extended price information
CHAPTER 11 s BUILDING A SAMPLE APPLICATION WITH ASP.NET AND ATLAS
The extended price information includes the bid and ask prices. These are, respectively, the current price that is being bid on the stock by prospective buyers and the one that is being asked for by sellers. When you make a purchase at the current market price, it will usually be between these two values, provided you are buying a large amount of shares in the stock. It also provides the opening price for the day, as well as the year s high and low. As you can see in Figure 11-7, Microsoft stock was quoted at 26.93, but pressure is moving it downward (the ask price and the bid price are both lower than this); however, it is up on its opening price of 26.80. Now let s take a look at the code that implements this. Figure 11-8 shows the ASP .NET web form that contains the server-side controls used to implement this functionality.
Figure 11-8. The ASP .NET designer view of the company information
As you can see in Figure 11-8, the application uses two UpdatePanel controls. Each of these contains a label. Each has an associated UpdateProgress control. The ScriptManager control on the page has Enable Partial Rendering set to true, meaning that updates to these UpdatePanel controls will not incur a full-page refresh. Finally, a timer control on the left triggers a timed update to the basic quote information every minute. Listing 11-1 shows the markup for these controls. Listing 11-1. Markup for the UpdatePanel Controls <table width="100%" cellpadding="2" style="border-width: 0"> <tr> <td style="width: 117px" class="style1"> <strong>Stock Ticker</strong> </td> <td style="width: 133px"> <asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged">MSFT </asp:TextBox> </td> <td class="style1" style="width: 289px"> <strong> <atlas:UpdatePanel ID="UpdatePanel3" runat="server"> <ContentTemplate>
CHAPTER 11 s BUILDING A SAMPLE APPLICATION WITH ASP.NET AND ATLAS

OnClick="btnMore_Click" CausesValidation="False" /> </ContentTemplate> </atlas:UpdatePanel> <atlas:UpdateProgress runat="server" ID="prog1"> <ProgressTemplate> Loading... </ProgressTemplate> </atlas:UpdateProgress> <atlas:TimerControl runat="server" Interval="60000" ID="quotetimer" OnTick="quoteTimer_tick" /> </strong> </td> <td class="style1" style="width: 147px"> <atlas:UpdatePanel ID="UpdatePanel4" runat="server"> <ContentTemplate> <asp:Label ID="lblMoreQuote" runat="server"> </asp:Label> </ContentTemplate> </atlas:UpdatePanel> <atlas:UpdateProgress runat="server" ID="prog2"> <ProgressTemplate> Loading... </ProgressTemplate> </atlas:UpdateProgress> </td> </tr> </table> The first UpdatePanel control (called UpdatePanel3) contains a Label control and a Button control. The Label control will contain the company name and current stock price, as you saw in Figure 11-6 and Figure 11-7. This gets updated whenever you enter a new stock ticker in the text box, and you ll see from the markup that this fires an event, called TextBox1_TextChanged, whenever the text changes. The code for this event is simple it calls the DoUpdate() function: protected void TextBox1_TextChanged(object sender, EventArgs e) { DoUpdate(); }
