Topic 2, Scenario 2 Overview

Fabrikam, Inc. is a realtor in the United States.

Fabrikam grants its customers access to a web site, where they can search for houses for rent and for sale. Its customers can enter basic requirements, such as location, number of rooms, dimensions, and a price range. The web site displays a list of houses that meet the customers#39; criteria. The customers can then view more details about each house and can add a listing to a favorites list.

Requirements Business Goals

Fabrikam plans to provide a more interactive experience for its customers. Fabrikam is

creating a video tour for each listing. The video tours can be used to visit the property virtually.

Fabrikam plans to create a Windows Store app on Windows 8.1 RT and Windows 8.1 Pro devices.

General Requirements

Fabrikam identifies the following general requirements for the app:

->The app interface must be available in English, Spanish, and French.

->The app must provide the customers with the ability to perform searches the same way that the current web site does.

->It is expected that the customers will view more than 3,000 pictures annually. The main page of the app must show a list of the last 10 pictures that were viewed.

->If pictures are added to a listing that is in a customer#39;s favorites list, the pictures must be downloaded automatically from Microsoft Azure. This must occur if the app is suspended or not running.

Printing Requirements

Customers must be able to print the details of a listing from the details page by clicking a button within the app. You plan to add the following XAML markup to the listing details page:

lt;Button x:Name=quot;btnPrintquot; Content-quot;Printquot; Click-quot;InvokePrintquot; /gt;.

Video Tour Requirements

Fabrikam identifies the following requirements for the video tours:

->Customers must be able to play the video tour on a different device by using a button within the app.

->When a customer clicks the details of a listing, the app must start downloading the video tour in the background.

->When the app starts, the app must verify whether there are any pending downloads, and resume any paused downloads.

->The last five viewed video tours that are not on the customer#39;s favorites list must be cached for subsequent viewing.

->Customers must be able to download all of the video tours for the properties that they added to their favorites list.

->The property details page must contain a MediaElement control that will be used to play the video tour of the property.

->When downloading the video tours, the app must remain responsive, and each download must be processed on a separate thread.

Question No: 7 – (Topic 3)

Users report performance issues when getting the location information associated with a photo. You suspect the app is encountering performance issues in the GetLocationAsync() method of the Environment class.

You need to enhance the performance of the GetLocationAsync() method of the app. What should you do?

  1. Remove the Compass initialization from the LoadSensors() method and initialize it within the GetLocationAsync() method.

  2. set the ReportInterval property of the Compass object to 16.

  3. set the ReportInterval property of the Compass object to 0.

  4. Move the locator variable to a class level variable and initialize it in the Environment

constructor.

Topic 4, Scenario 4 Background

You are developing a Windows Store app named Picture Sharer. The app will allow users to capture, modify, caption, and share pictures.

Application Structure

The ShareImageButton and GetContactsButton controls use the same foreground color. The foreground color might change in the future.

The following code defines a custom button style named ButtonStyleRed:

Dumps4Cert 2018 PDF and VCE

Relevant portions of the app files are shown. (Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.)

Business Requirements

The app must meet the following business requirements:

->Allow users to capture and retrieve pictures, modify pictures by adding a shading effect, and add captions to images.

->Support only Landscape and Landscape-flipped orientation.

->Allow users to capture and retrieve pictures, modify pictures by adding a shading effect, and add captions to images.

->Support only Landscape and Landscape-flipped orientations.

->Ensure that users can select and modify images from the PictureChooserPage page.

->Ensure that users can change the magnification of the selected image and resize the image by using pinch and stretch gestures. Scaling should be fluid and precisely controlled by the user.

The app must be localized for the French Canadian market

Technical Requirements

The app must meet the following technical requirements:

->Scroll bars must not be visible.

->The CaptionTextBlock and CaptionTextBox controls must appear side by side, without overlapping and on the same line. The CaptionTextBox control should appear to the right of the CaptionTextBlock control.

->The ContactPicker object must be filtered to display only email addresses.

->Minimize the code that is required to implement optical zoom functionality.

You must perform the following tasks:

->Handle the Click event of the GetPictureButton control to switch from the current page to the PictureChooserPage page.

->After the user selects an image on the PictureChooserPage page, ensure that the app navigates back to the PictureSharerMainPage page.

->Track the current screen orientation and page size by updating the

_currentViewState, _currentHeight and _currentWidth fields every time the screen orientation or page size changes.

->Create a style named ButtonStyleWhite that inherits all the style settings of the

ButtonStyleRed style except the border color; the border color must be white. The ButtonStyleWhite style must automatically update with any changes that are made to the ButtonStyleRed style.

->Create a resource named ButtonForegroundColor to implement the button

foreground color so that it can be referenced in XAML by using the following standard syntax: Foreground=quot;{StaticResource ButtonForegroundColor}quot;

->Ensure that the OnNavigatedToO method updates the current picture when a new

picture is selected.

->Change the background for the root Grid element to a vertical gradient that transitions from black at the top to maroon at the bottom. Create a resource named GridBackgroundGradientBrush to hold the requested gradient.

While testing the app, you observe the following results:

->An exception is being thrown in the GetContactsCompleted event handler when the retrieved email address is assigned to the RecipientsTextBlock control. The exception message states: quot;The application called an interface that was marshalled for a different thread.quot;

->When users navigate away from the PictureSharerMainPage page, information that was entered in the CaptionTextBox control is lost.
