Microsoft 70-544 : TS: Ms Virtual Earth 6.0, Application Development

The locations of the vehicles of your company are available as coordinates. You need to display only the current location of a vehicle on a Virtual Earth 6.0 base map layer. What are two possible code segments you can use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A. map = new VEMap('myMap'); map.LoadMap(); layer = new VEShapeLayer(); map.AddShapeLayer(layer); shape = new VEShape(VEShapeType.Pushpin, new
  VELatLong(latitude, longitude)); layer.AddShape(shape);
• B. map = new VEMap('myMap'); map.LoadMap(); map.AddPushpin(new
  VELatLong(longitude, latitude));
• C. map = new VEMap('myMap'); map.LoadMap(); layer = new VEShapeLayer(); map.AddShapeLayer(layer); shape = new VEShape(VEShapeType.Pushpin, new
  VELatLong(longitude, latitude)); layer.AddShape(shape);
• D. map = new VEMap('myMap'); map.LoadMap(); shape = new
  VEShape(VEShapeType.Pushpin, new VELatLong(latitude, longitude));
  map.AddShape(shape);
• E. map = new VEMap('myMap'); map.LoadMap(); map.AddPushpin(new
  VELatLong(latitude, longitude));

You are creating a Virtual Earth 6.0 application. The application allows users to enter an address and view the corresponding mapped location. A Print Preview link appears next to the location. The link opens a pop-up window that contains the location information in a query string.
The map load in the pop-up window is defined by the following code segment. (Line numbers are included for reference only.)
0 1 var loc = ... ;
0 2 var map = null;
0 3 function GetMap(){
0 4 map = new VEMap('PrintPreviewMap');
0 5 map.LoadMap();
0 6 ...
0 7 }
The variable named loc in the code segment is an object that contains the id, address, latitude, longitude, and zoom properties that are present in the query string.
You need to ensure that the pop-up window meets the following requirements:
It uses the properties in the query string to display the location.
It does not display map controls.
Which code segment should you insert at line 06?

• A. map.SetCenterAndZoom(new VELatLong(loc.latitude, loc.longitude), loc.zoom); map.AddShape(new VEShape(VEShapeType.Pushpin, new VELatLong(loc.latitude, loc.longitude))); map.HideDashboard();
• B. map.PanToLatLong(new VELatLong(loc.latitude, loc.longitude));
  map.AddPushpin(map.GetCenter()); map.SetZoom(loc.zoom); map.HideDashboard();
• C. map.FindLocation(loc.address); map.AddShape(new VEShape(VEShapeType.Pushpin, new VELatLong(loc.latitude, loc.longitude)));
  document.getElementById('map_dashboard').style.display = "none";
• D. map.PanToLatLong(new VELatLong(loc.latitude, loc.longitude)); map.AddShape(new
  VEShape(VEShapeType.Pushpin, new VELatLong(loc.latitude, loc.longitude))); document.getElementById(map_dashboard).style.display = "none";

You are creating a Web application by using the Virtual Earth 6.0 map control in the
Microsoft Visual Studio environment. A Web page in the application is programmed by using the client-side JavaScript code. You insert break points at appropriate locations within the code. When you debug the application, you find that you are able to step into the server-side code. However, you are unable to step into the client-side JavaScript code.
You need to debug the client-side JavaScript code. What should you do?

• A. In Microsoft Internet Explorer, select the Enable Display a notification about every script error option in the Internet Options dialog box.
• B. In Visual Studio, select the Attach to Process option from the Debug menu. Then attach the debugger to the Microsoft Internet Explorer process.
• C. In Microsoft Internet Explorer, clear the Disable Script Debugging (Internet Explorer) option in the Internet Options dialog box.
• D. In the client-side JavaScript code, insert the Debugger command before each break point.

You are creating a Virtual Earth 6.0 application that retrieves locations from a Microsoft SQL Server 2005 database.
A stored procedure will be used to retrieve only locations that lie within the currently displayed map area. You need to define the boundary within which the locations displayed on the map must lie. How should you define the boundary?

• A. points represented by the bottom-right and top-left latitude and longitude coordinates
• B. the center point of a circle whose radius is equal to the size of the map based on latitude and longitude coordinates
• C. the center point of a circle whose radius is equal to the size of the map based on pixel coordinates
• D. points represented by the bottom-right and top-left pixel coordinates

You are creating a Virtual Earth 6.0 application.
A Web page of the application contains the following code segment.
control = document.createElement("div");
control.id = "CustomControl";
A custom control must be added on top of the map on the Web page.
You need to ensure that the custom control responds only to its own mouse-click events.
Which code segment should you use?

• A. control.innerHTML = "<input type='button' value='Click' onclick='ClickHandler()' />"; map.AddControl(control);
• B. control.innerHTML = "<input type='button' value='Click' onclick='ClickHandler()' />"; document.getElementById('Map').appendChild(control);
• C. control.innerHTML = "<input type='button' value='Click' />"; map.AddControl(control); map.AttachEvent("onclick", ClickHandler);
• D. control.innerHTML = "<input type='button' value='Click' />";
  document.getElementById('Map').appendChild(control);
  document.getElementById('CustomControl').attachEvent("onclick", ClickHandler);
