Microsoft TS: Windows Applications Development with Microsoft .NET Framework 4 Sample Questions:

1. You are developing a Windows Presentation Foundation (WPF) application page.
The controls on the page must be enclosed within a single rectangular border. The border must contain an image in the header.
You need to select a control to use as a container.
Which control should you select?

A) GroupBox
B) Expander
C) Border
D) Rectangle

2. DRAG DROP
You have a Windows Presentation Foundation (WPF) application named App1.
You plan to deploy App1 by using ClickOnce.
You need to ensure that App1 meets the following security requirements:
- The assembly that contains App1 must be visible from a COM component. - Each time Appl runs, an End-User License Agreement (EULA) must appear.
- App1 must be able to open files on local drives if the application is deployed from a
file server. - App1 must be prevented from opening files on local drives if the application is deployed from a Web server.
Which file should you modify for each requirement? (To answer, drag the appropriate files to the correct requirements. Each file may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

3. You use Microsoft .NET Framework 4 to create a Windows Forms application.
You write the following code segment. (Line numbers are included for reference only.)
01 NotInheritable Class FormSettings
02 Inherits ApplicationSettingsBase 03
04 Public Property Description() As [String]
05 Get
06 Return DirectCast(He("Description"), [String])
07 End Get
08 Set
09 Me("Description") -value
10 End Set
11 End Property
12 End Class
You need to ensure that the first time each user opens the application, a text field displays the following message: "Please enter your setting."
Which code segment should you insert at line 03?

A) <UserScopedSetting() >
<DefaultSettingValue("Please enter your setting.")>
B) <ApplicationScopedSetting()>
<DefaultSettingValue("Please enter your setting.")>
C) <UserScopedSetting()>
<SettingsDescription("Description: Please enter your setting.")>
D) <ApplicationScopedSetting()>
<SettingsDescription("Description: Please enter your setting.")>

4. You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You add a custom command as a resource. The key of the command is saveCommand.
You write the following code fragment. (Line numbers are included for reference only.)
01 < Canvas>
02
03 <Button>
04
05 </Bucton>
06 </Canvas>
You need to ensure that saveCommand is executed when the user clicks the Button control.
What should you do?

A) Insert the following code fragment at line 02.
<Canvas.CommandBindings>
<ComtnandBinding Command="{StaticResoucce saveComroand}" /></Canvas.CommandB
indings>
Replace line 03 with the following code fragment.
<Bucton CommandTarget="{Binding RelativeSource={RelativeSource Self},
Path=Parent>">
B) Insert the following code fragment at line 04.
<Button.CommandBindings>
<CoRimandBinding Comitiand="( StaticResource saveCoimtiand}"
/></Button.CommandBindings>
C) Insert the following code fragment at line 02.
<Canvas.CommandBindings>
<CommandBinding Command="{StaticResoucce saveComroand}"
/></Canvas.CommandBindings>
Replace line 03 with the following code fragment.
<Buccon CommandPararoecec="{Binding RelativeSource=(RelaciveSource Self},
Path=Parent>">
D) Insert the following code fragment at line 04.
<Button.Coiranand>
<StaticResource ResourceKey="saveCoKiniand" /></Button.Command>

5. You are developing a Windows Presentation Foundation (WPF) application.
The application contains the following code in the code-behind file for an application window. (Line numbers are included for reference only.)
01 Dim stack As StackPanel = New StackPanel() 02 Content = stack 03 For i As Integer = 0 To 9 04 Dim btn As Button = New Button () 05 btn.Name = Convert.ToChar (Asc("A") + i) .ToString () 06 btn.Content - btn.Name "says" "Click me1" 07 08 Next
You need to ensure that all of the Button controls that are defined in this code segment appear in the application window.
Which code segment should you insert at line 07?

A) Content = New Button ()
With {Name = (Asc("A") + i) .ToString(), .
Content = (i & " says Click me'").ToString()}
B) stack.Children.Add (btn)
C) stack.Children.Insert (i + 1, btn)
D) Content = btn
