    QUESTION 26
    You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
    You write the following code segment to create a JavaScript file named CalculatorScript.js.
    function divide(a, b) {
     if (b == 0) {
     var errorMsg = Messages.DivideByZero;
     alert(errorMsg); return null;
     }
     return a/b;
    }
    You embed the CalculatorScript.js file as a resource in a Class Library project.
    The namespace for this project is Calculator.Resources.
    The JavaScript function retrieves messages from a resource file named MessageResources.resx by using the JavaScript Messages object.
    You add an AJAX Web form in the ASP.NET application. You reference the Class Library in the application.
    You add an ASP.NET AJAX ScriptReference element to the AJAX Web form.
    You need to ensure that the JavaScript function can access the error messages that are defined in the resource file.
    Which code segment should you add in the AssemblyInfo.cs file?
    A.[assembly: ScriptResource ("CalculatorScript", "MessageResources", "Messages")]
    B.[assembly: ScriptResource ("CalculatorScript.js", "MessageResources.resx", "Messages")]
    C.[assembly: ScriptResource ("Calculator.Resources.CalculatorScript.js", "Calculator.Resources.MessageResources", "Messages")]
    D.[assembly: ScriptResource ("Calculator.Resources.CalculatorScript", "Calculator.Resources.MessageResources.resx", "Messages")]
    Answer: C
    QUESTION 27
    You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
    You create an AJAX-enabled Web form by using the following code fragment.
    
    
    
     ...
    
    
    When the updFirstPanel UpdatePanel control is updated, a dynamic client script is registered.
    You write the following code segment in the code-behind file of the Web form. (Line numbers are included for reference only.)
    01 protected void Page_Load(object sender, EventArgs e)
    02 {
    03 if(IsPostBack)
    04 {
    05 string generatedScript = ScriptGenerator.GenerateScript();
    06
    07 }
    08 }
    You need to ensure that the client-script code is registered only when an asynchronous postback is issued on the updFirstPanel UpdatePanel control.
    Which code segment should you insert at line 06?
    A.ClientScript.RegisterClientScriptBlock(typeof(TextBox), "txtInfo_Script", generatedScript);
    B.ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "txtInfo_Script", generatedScript, false);
    C.ClientScript.RegisterClientScriptBlock(typeof(Page), "txtInfo_Script", generatedScript);
    D.ScriptManager.RegisterClientScriptBlock(txtInfo, typeof(TextBox), "txtInfo_Script", generatedScript, false);
    Answer: D
    QUESTION 28
    You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
    The application contains the following code segment.
    public class CapabilityEvaluator {
     public static bool ChkScreenSize( System.Web.Mobile.MobileCapabilities cap, String arg) {
     int screenSize = cap.ScreenCharactersWidth * cap.ScreenCharactersHeight;
     return screenSize < int.Parse(arg);
     }
    }
    You add the following device filter element to the Web.config file.
    
    You need to write a code segment to verify whether the size of the device display is less than 80 characters.
    Which code segment should you use?
    A.MobileCapabilities currentMobile; currentMobile = Request.Browser as MobileCapabilities;
    if(currentMobile.HasCapability("FltrScreenSize","80")) {
    }
    B.MobileCapabilities currentMobile; currentMobile = Request.Browser as MobileCapabilities;
    if(currentMobile.HasCapability( "FltrScreenSize","").ToString()=="80") {
    }
    C.MobileCapabilities currentMobile; currentMobile = Request.Browser as MobileCapabilities;
    if (currentMobile.HasCapability( "CapabilityEvaluator.ChkScreenSize", "80")) {
    }
    D.MobileCapabilities currentMobile; currentMobile = Request.Browser as MobileCapabilities;
    if (currentMobile.HasCapability( "CapabilityEvaluator.ChkScreenSize", "").ToString()=="80") {
    }
    Answer: A
    QUESTION 29
    You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. The application has a mobile Web form that contains the following ObjectList control.
    
    
    
    
    You create an event handler named ObjectListCtrl_ItemCommand.
    You need to ensure that the ObjectListCtrl_ItemCommand handler detects the selection of the CmdDisplayDetails item.
    Which code segment should you write?
    A.public void ObjectListCtrl_ItemCommand( object sender, ObjectListCommandEventArgs e) {
    if (e.CommandName == "CmdDisplayDetails") {
    } }
    B.public void ObjectListCtrl_ItemCommand( object sender, ObjectListCommandEventArgs e) {
    if (e.CommandArgument.ToString() == "CmdDisplayDetails") {
    } }
    C.public void ObjectListCtrl_ItemCommand( object sender, ObjectListCommandEventArgs e) {
    ObjectListCommand cmd = sender as ObjectListCommand;
    if (cmd.Name == "CmdDisplayDetails") {
    } }
    D.public void ObjectListCtrl_ItemCommand( object sender, ObjectListCommandEventArgs e) {
    ObjectListCommand cmd = e.CommandSource as ObjectListCommand;
    if (cmd.Name == "CmdDisplayDetails") {
    } }
    Answer: A
    QUESTION 30
    You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
    All the content pages in the application use a single master page. The master page uses a static navigation menu to browse the site.
    You need to ensure that the content pages can optionally replace the static navigation menu with their own menu controls.
    What should you do?
    A.Add the following code fragment to the master page
