Drag and Drop Question
You are planning the architecture of a new Windows Store style e-commerce app. You need to maximize reusability by breaking app components into logical layers. To which logical layers should you assign the components? (To answer, drag the appropriate components to the correct layers in the answer area. Each component 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.)
You are developing a Windows Store app. The app will use a model that is defined by using the following code:
You need to create a class to represent a collection of Customer objects. The class will be used for data binding. The solution must ensure that if changes are made to the objects of the class, a notification will be sent to the user interface (UI) controls to which the collection is bound. You have the following signature:
public classCustomerList : Target 1<Target 2>
Which elements should you include in Target 1 and Target 2 to complete the signature for the collection class? (To answer, drag the appropriate elements to the correct targets. Each element 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.)
A class named AccountViewModel includes a property named Name that will be bound to a control. The Name property will occasionally be updated programmatically. The updated values must be reflected in the bound control. You need to implement the interface so that the AccountViewModel class can inform WinRT when there is a new value to display. You have the following code:
Which code snippets should you insert in Target 1 and Target 2 to complete the code? (To answer, select the correct code snippet from each drop-down list in the answer area.)
You develop a Windows Store app. The Capabilities section of the app manifest is configured as shown in the exhibit. (Click the Exhibit button.)
To answer, complete each statement according to the information presented in the exhibit. Each correct selection is worth one point.
You are developing a Windows Store app. The app includes the following event procedure:
Void OnSettingsPaneOpened(SettingsPanesettingsPane, SettingsPaneCommandsRequestedEventArgseventArga)
You need to call the event procedure when the user opens the settings pane. Which three code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)
You are developing a Windows Store app Chat provides users with the ability to select a video file from the file system. Once the file is selected, the video begins to play. this.media is declared as a MediaElement in VideoPage.xaml and _position is declared as a private TimeSpan member that stores the point at which the video stopped when the app was terminated. You need to ensure that if the app is terminated, the next time the app starts, the app resumes playing the video at the point the video was stopped. You have the following code: (Line numbers are included for reference only.)
Which code segments should you insert at lines 04, 13, and 17? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code segment 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.)
You are developing a Windows Store reporting app for corporate use. The app authenticates users by using Active Directory Domain Services (AD DS) credentials. You need to ensure that users have the option of saving their credentials when they log in to the app. You have the following code:
Which code snippets should you insert in Target 1, Target 2, and Target 3 to complete the code? (To answer, drag the appropriate code snippets to the correct target in the answer area. Each code snippet 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.)
You are developing a dependency property named TotalAmount for a Windows Store app. The TotalAmount property must default to zero. The class that contains the TotalAmount property must provide a class property that gets and sets the value of the dependency property. You need to create the dependency property and the class property. You have the following code:
