Hey Now Everybody,
In this 11th post of the Catto Code Crackin series we’ll continue with the section ‘real world exam question concepts’. In the .NET 3.5 * the .NET 4 exam there are questions. Let’s inspect some concepts & properties that will be the skills measured.
Microsoft announced the .NET 4.0 Beta Exams on St. Patrick’s Day which are a free exam & if passed you get certified. Much of the study & prep materials are not available yet, therefore I’ve been studying for a similar exam 70-562 which is the .NET 3.5 ASP.NET Application Development. I hope by posting this content it will help myself along with other people in the community learn & get excited about .NET 4. If you are serious about studying for a MS Exam 2 must have resources: the Self Paced training books are a great books to buy along with practice exams from eBay.

71 QUESTION 71 AJAX
01 function updateLabelControl(labelId, newText) {
02 var label = $find(labelId);
03 label.innerHTML = newText;
04 }
The client script function uses ASP.NET AJAX and updates the text of any Label control in the Web form.
When you test the client script function, you discover that the Label controls are not updated.
JavaScript error message in the browser: "'null' is null or not an object." You need to resolve the error.

06
07 }
08
09 function errorHandler(sender, args)
10 {
11
12 }
13 </script>
Ensure that the application performs the following tasks:
Use a common clien-script function named errorHandler.
Update a Label control that has an ID named lblEror with the error message.
Prevent the browser from displaying any message box or Javascript error
A. Insert the following code segment at line 06.
pageMgr.add_endRequest(errorHandler);
Insert the following code segment at line 11.
if (args.get_error() != null) {
$get('lblError').innerHTML = args.get_error().message;
args.set_errorHandled(true);
}

09 </script>
10
11 <asp:ScriptManager ID="ScriptManager1"
12 runat="server" />
13 <asp:TextBox runat="server" ID="TextBox1" />
Create and initialize a client behavior named MyCustomBehavior by using the initComponents function. You also need to ensure that
MyCustomBehavior is attached to the TextBox1 Textbox control.
insert at line 06 the following code:
B. $create(MyCustomBehavior, null, null, null, $get('TextBox1'));
74 AJAX Authentication
<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 cont
used to call the client-side script.
.js file:
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.
Ensure that the following workflow is maintained:
On successful authentication, the onLoginCompleted clien-script function is called to notify the user.
On failure of authentication, the onLoginFailed clien-script function is called to display an error message.
Insert at line 06 the following code
A. var auth = Sys.Services.AuthenticationService;
auth.login(username, password, false, null, null,onLoginCompleted, onLoginFailed, null);
QUESTION 75 web.configDeviceSpecific

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.
Insert at line 02 the following code:
A. <DeviceSpecific>
<Choice Filter="isHtml" ImageUrl="highRes.jpg" />
<Choice ImageUrl="lowRes.gif" />
</DeviceSpecific>
76 Mobile
<mobile:StyleSheet id="MyStyleSheet" runat="server">
<mobile:Style Name="StyleA" Font-Name="Arial" Font-Bold="True" Wrapping="NoWrap">
</mobile:Style>

The application must redirect the original URL to a different ASPX page.
Ensure that the users cannot view the original URL after the page is executed.
You also need to ensure that each page execution requires only one request from the client browser.
C. Use the HttpContext.Current.RewritePath method to transfer execution to the correct ASPX page.
80 Data
The application uses Session objects. You are modifying the application to run on a Web farm.
Ensure that the application can access the Session objects from all the servers in the Web farm.
You also need to ensure that when any server in the
Web farm restarts or stops responding, the Session objects are not lost.
B. Use the SQLServer Session Management mode to store session data in a common Microsoft SQL Server 2005 database.

web.config
The Web site uses C# as the programming language.
You plan to add a code file written in Microsoft VB.NET to the application.
This code segment will not be converted to C#.
Web.config\
<compilation debug="false">
<codeSubDirectories>
<add directoryName="VBCode"/>
</codeSubDirectories>
</compilation>
You need to ensure that the following requirements are met:
The existing VB.NET file can be used in the Web application The file can be modified and compiled at run time What should you do?
B. Create a new folder named VBCode inside the App_Code folder of the application Place the VB.NET code file in this new folder

These classes are modified frequently.
Ensure that the application is recompiled automatically when a utility class is modified.
A. Create the Web application by using a Microsoft Visual Studio ASP.NET Web site Add the utility classes to the App_Code subfolder of the Web application
83 Custom Server Controls web.config Cashing
You add a Web page named HomePage.aspx in the application. The Web page contains different controls.
You add a newly created custom control named CachedControl to the Web page.
You need to ensure that the following requirements are met:
The custom control state remains static for one minute The custom control settings do not affect the cache settings of other elements in the Web page What
A. Add the following code fragment to the Web.config file of the solution.
<caching>
<outputCacheSettings>
<outputCacheProfiles>
<add name="CachedProfileSet" varyByControl="CachedControl" duration="60" />
</outputCacheProfiles>
</outputCacheSettings>
</caching>
That is all there will be more,
