You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. The application contains a mobile Web page. 
You add the following StyleSheet control to the Web page：  
<mobile：StyleSheet id="MyStyleSheet" runat="server">  
<mobile：Style Name="StyleA" Font-Name="Arial" Font-Bold="True" Wrapping="NoWrap">  </mobile：Style>

You create a Microsoft ASP.NET Web application by using the Microsoft .NET Framework version 3.5. 
The application contains the following device filter element in the Web.config file：  
<filter name="isHtml" compare="PreferredRenderingType" argument="html32" />   
The application contains a Web page that has the following image control：  
01 <mobile：Image ID="imgCtrl" Runat="server">  
02 ► 
03 </mobile：Image>   
You need to ensure that the following conditions are met： 
the imgCtrl Image control displays the highRes.jpg file if the Web browser supports HTML   the imgCtrl Image control displays lowRes.gif if the Web broser does not support HTML.

You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. You create a login Web form by using the following code fragment：  
<asp：ScriptManager ID="ScriptManager1" runat="server" />  
<asp：TextBox runat="server" ID="txtUser" Width="200px" />  
<asp：TextBox runat="server" ID="txtPassword" Width="200px" />  
<asp：Button runat="server" ID="btnLogin" Text="Login"   
OnClientClick="login（）； return false；" />   
When a user clicks the btnLogin Button control， the login（） client-side script is called to authenticate the user. The credentials provided in the TextBox controls are used to call the client-side script. 
You also add the following client-script code fragment in the Web form：  
01 <script type="text/javascript">  
02   function login（） {  
03     var username = $get（’txtUser’）.value；  
04     var password = $get（’txtPassword’）.value；  
05  
06 ►   // authentication logic. 
07   }  
08   function onLoginCompleted（validCredentials， userContext，  
09     methodName）  
10   {  
11     // notify user on authentication result. 
12   }  
13  
14   function onLoginFailed（error， userContext， methodName）  
15   {  
16     // notify user on authentication exception. 
17   }  
18 </script>  
The ASP.NET application is configured to use Forms Authentication. The ASP.NET AJAX authentication service is activated in the Web.config file. 
You need to ensure that the following workflow is maintained： 
on successful authentication， the onLoginCompleted client-script function is called to notify the user. 
on failure of authentication， the onLoginFailed client-script function is called to display an error message.
