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

1. 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 sealed class FormSettings : ApplicationSettingsBase
02 {
04 public String Description
05 {
06 get {return (String)this["Description"]; }
07 set {this["Description"] = value;}
08 }
09 }
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() ]
[SettingsDescription("Description: Please enter your setting.")]
B) [UserScopedSettingO ]
[DefaultSettingValue("Please enter your setting.")]
C) [ApplicationScopedSetting() ]
[SettingsDescription("Description: Please enter your setting.")]
D) [ApplicationScopedSetting() ]
[DefaultSettingValue("Please enter your setting.")]

2. You use Microsoft .NET Framework to create a Windows Presentation Foundation (WPF) application.
You create a window that contains a Button control and a MenuItem control. Both controls are labeled "Add sugar." The Command properties of the Button and MenuItem controls are set to the same RoutedCommand named AddSugarCommand.
You write the following code segment.
Private Sub CanAddSugar(sender As Object, e As CanExecuteRoutedEventArgs)
...
End Sub
You need to ensure that when the CanAddSugar method sets e.CanExecute to false, the MenuItem and Button controls are disabled.
What should you do?

A) Add a CommandBinding object to the CommandBinding property of the MenuItem control. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.
B) Create an event handler for the CanExecuteChanged event of the AddSugarCommand command. Call the CanAddSugar method from within the event handler.
C) Add a CommandBinding object to the CommandBindings property of the window. Set the Command property of CommandBinding to the AddSugarCommand command. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.
D) Inherit the AddSugarCommand from the RoutedUICommand class instead of the RoutedCommand class. Call the CanAddSugar method from within the constructor of the AddSugarCommand command.

3. 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,
Converter={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 object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
return (decimal.Parse(parameter.ToString()) / 100);
}
B) public object Convert(object value. Type targetType,
object parameter, CultureInfo culture)
{
return ((decimal)parameter).ToString(nPn);
}
C) public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
return (decimal.Parse(value.ToString()) / 100);
}
D) public object Convert (object value, Type targetType,
object parameter, CultureInfo culture)
{
return ((decimal)value).ToString("P");
}

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 develop a Windows Presentation Foundation (WPF) application. This application is
used to output data trends to customer service representatives.
A data trend analysis is performed in a function named UpdateTrendData. The trend
analysis is a long-running process.
The application contains the following code segment.
Class MainWindow
Private Sub UpdateData(By Val arg As Object) Dim data As Double = UpdateTrendData()
... End Sub
End Class
UpdateData is currently invoked on the UI thread when the form is first displayed.
You need to process the data in a manner that does not cause the UI to freeze.
What should you do?

A) Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Normal.
B) Use ThreadPool.SetMaxThreads(2,2) and invoke UpdateData.
C) Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Background.
D) Use ThreadPool.QueueUserWorkltem to invoke UpdateData.
