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

1. 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 </Button>
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 04.
<Button.CommandBindings>
<ConrniandBinding Command="{StaticResource saveCommand}"
/></Button.CommandBindings>
B) Insert the following code fragment at line 04.
<Button.Comrtiand>
<StaticResource ResourrceKey="saveComr[iand" />
</Button.Command>
C) Insert the following code fragment at line 02.
<Canvas.CommandBindings>
<CommandBinding Command="{StaticResource saveConmand)"
/></Canvas.CommandBindings>
Replace line 03 with the following code fragment.
<Button CommandTarget="{Binding RelativeSource={RelativeSource Self), Path=Parent}">
D) Insert the following code fragment at line 02.
<Canvas.Commandsxndings>
<CommandBinding Command="{StaticResource saveCommand}"
/></Canvas.CommandBindings>
Replace line 03 with the following code fragment.
<Button CommandParameter="{Binding RelativeSource={RelativeSource Self),
Path=Parent>">

2. You are developing a Windows Presentation Foundation (WPF) application for a travel reservation system.
You need to ensure that users can select a range of travel dates.
What should you do?

A) Add a single DatePicker control to the design surface.
B) Add a single Calendar control to the design surface.
C) Add a single MediaElement control to the design surface to display a calendar.
D) Add the appropriate Windows Forms references to the project references. Add a single windows Forms DoteTimePicker control to the design surface.

3. You use Microsoft .NET Framework 4 to create a Windows Forms application. You have a dataset as shown in the following exhibit.

---
You plan to add a DataGridView to display the dataset.
You need to ensure that the DataGridView meets the following requirements:
Shows Order Details for the selected order. Shows only Order Details for items that have UnitPrice greater than 20 Sorts Products by ProductName
Which code segment should you use?

A) ordersBindingSource.DataSource = producxsBindingSource; ordersBindingSource.DataMember = "FK_Order_Details_Products"; productsBindingSource.Filter = "UnitPrice > 20"; productsBindingSource.Sort = ProductName";
B) order_DetailsDataGridViev.DataSource = ordersBindingSource; order_DetailsBindingSource.Filter = "UnitPrice > 20"; productsBindingSource.Sort "ProductName";
C) order DetailsBindingSource.DataSource = ordersBindingSource; order_DetailsBindingSource.DataMember = "FK_Order_Details_Orders". order_DetailsBindingSource .Filter = "UnitPrice > 20"; productsBindingSource.Sort "ProductName"; C
D) productsDataGridView.DataSource = ordersBindingSource; productsBindingSource.Filter = "UnitPrice > 20"; productsBindingSource.Sort = "ProductName";

4. You use Microsoft .NET Framework 4 to create a Windows Forms application.
You need to allow the user interface to use the currently configured culture settings in the Control Panel.
Which code segment should you use?

A) Thread.CurrentThread.CurrentUICulcure = CultureInfo.InstalledUICulture
B) Thread.CurrentThread.CurrentCulture = Thread.CurrentThread.CurrentUICulture
C) Thread.CurrentThread.CurrentCulture = CultureInfo.InstalledUICulture
D) Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture

5. You are developing a Windows Presentation Foundation (WPF) application. The application contains a converter named DateOutputConverter that formats dates.
The window is defined as follows. (Line numbers are included for reference only.)

The window must display the OrderDate value found in shippedOrder. The text box must display the OrderDate formatted by the DateOutputConverter.
You need to ensure that the OrderDate is displayed and formatted correctly.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Insert the following code at line 07.
<m:DateCutputConverter x:Xey="internationalDataConverter"/>
B) Insert the following code at line 10.
<TextBox text="'Binding OrderDate,
Converter= {StaticRescurce interationalDateConverter)}" DataContext="{StaticResource
ResourceKey=shippedOrder}"/>
C) Insert the following code at line 10.
<TextBox text="{Binding OrderDate}"/>
D) Insert the following code at line 07.
<m:DateCutputConverter x:Key="DateOutputConverter"/>
