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

1. You are developing a Windows Presentation Foundation (WPF) application. The window has the following markup. (Line numbers are included for reference only.)

You need to ensure that all ListBox controls have a border that matches the background color of the ListBox template.
Which markup segment should you insert at line 15?

A) <Border Background="{Binding ListBox.BackGround)">
<ContentPresenter />
</Border>
B) <Border Background="TemplateBinding ListBox.Background)">
<ContentPresenter />
</Border>
C) <Border Background="TemplateBinding ListBox.Background}">
<ItemsPresenter /> </Border>
D) <Border Background="<Binding ListBox.Background)">
<ItemsPresenter />
</Border>

2. You are developing a Windows Presentation Foundation (WPF) application.
A UserControl named usercontroll contains the following controls.
<StackPane1>
<Label Name="Label1" Content="Hello Exam!!!" />
</StackPanel>
You need to ensure that the content of the label displays "New Content!!!" programmatically from the code-behind of the application window that contains the UserControl.
Which code segment should you use?

A) var label = userControll.FindName ("label1") as Label;
label.Content = "New Content!!!";
B) var label = userControl1.FindResource("label1") as Label;
label.Content = "New Content!!!";
C) userControl1.Content = "New Content!!!";
D) DependencyProperty dp =
DependencyPropercy.Register("label1",
typeof(Label), typeof(Window), new PropertyMetadata("New Content!!!"));
userControl1.CoerceValue(dp);

3. You are developing a Windows Presentation Foundation (WPF) application.
The application is for commercial use and requires a valid license key to be entered. You create a project type of Class Library that contains the code to validate license keys.
You need to ensure that the user enters a valid license key during installation of the software.
Which deployment should reference the class library?

A) ClickOnce
B) XBAP
C) XCopy
D) Setup Project

4. HOTSPOT
You use Microsoft .NET Framework 4 to create a Windows Presentation Framework (WPF)
application.
The application contains a DockPanel named DockPanel1. DockPanel1 contains a ListBox
named List1 and a Button named Button 1.
End-users discover that when they run the application, their mouse pointer disappears
when they hover over List1.
You run the application in debug mode and open the WPF Tree Visualizer.
You need to identify which property causes the issue.
Which property should you identify? (To answer, select the appropriate property in the
answer area.)

5. You are developing a Windows Presentation Foundation (WPF) application.
Users can enter formatted percentages into text boxes.
The markup is as follows.
<TextBox Text="{Binding Path=Percentage,
Converters StaticResource PercentValueConverter}}" />
Percentage is a decimal property.
You need to store the percentages as their decimal values, not their display values.
Which code segment should you use?

A) Public Function ConvertBack{
ByVal value As Object, ByVal targetType As Type,
ByVai parameter As Object, ByVal culture As CultureInfo)
As Object
Return (Decimal.Parse(value.ToString()) / 100)
End Function
B) Public Function Convert (
ByVal value As Object, ByVal targetType As Type,
ByVal parameter As Object, ByVal culture As CultureInfo)
As Object
Return CDec (parameter) .ToStrmg ("P")
End Function
C) Public Function Convert (
ByVal value As Object, ByVal targetType As Type,
ByVal parameter As Object, ByVal culture As CultureInfo)
As Object
Return CDec(value).ToString("P")
End Function
D) Public Function ConvertBack(
ByVal value As Object, ByVal targetType As Type,
ByVal parameter As Cliiert, ByVal culture As cultureInfo)
As Object
Return (Decimal.Parse (parameter.ToString ()) / 100)
End Function
