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

You define a callback function that updates the data on a Virtual Earth 6.0 map. You need to ensure that the callback function runs every time a user pans or zooms the Virtual Earth map. Which event should you attach to the Virtual Earth map?

• A. onobliquechange
• B. onchangeview
• C. oninitmode
• D. onmousemove
• E. onloadmap

You need to draw a straight red line between the start and end points of a calculated route.
Which code segment should you use?

• A. var locationArray = new Array(); var len = route.Itinerary.Segments.length; locationArray.push(route.Itinerary.Segments[1].LatLong);
  locationArray.push(route.Itinerary.Segments[len].LatLong); shape = new
  VEShape(VEShapeType.Pushpin, locationArray); shape.SetLineColor(new VEColor(255,
  0, 0, 0.5)); layer.AddShape(shape);
• B. var locationArray = new Array(); var len = route.Itinerary.Segments.length; locationArray.push(route.Itinerary.Segments[0].LatLong);
  locationArray.push(route.Itinerary.Segments[len].LatLong); shape = new
  VEShape(VEShapeType.Polyline, locationArray); shape.SetLineColor(new VEColor(255, 0,
  0, 0)); shape.HideIcon(); layer.AddShape(shape);
• C. var locationArray = new Array(); var len = route.Itinerary.Segments.length; locationArray.push(route.Itinerary.Segments[0].LatLong);
  locationArray.push(route.Itinerary.Segments[len-1].LatLong); shape = new
  VEShape(VEShapeType.Polyline, locationArray); shape.SetLineColor(new VEColor(255, 0,
  0, 0)); layer.AddShape(shape);
• D. var locationArray = new Array(); var len = route.Itinerary.Segments.length; locationArray.push(route.Itinerary.Segments[0].LatLong);
  locationArray.push(route.Itinerary.Segments[len-1].LatLong); shape = new
  VEShape(VEShapeType.Polyline, locationArray); shape.SetLineColor(new VEColor(255, 0,
  0, 0.5)); shape.HideIcon(); layer.AddShape(shape);

The intranet site of your company displays an interactive map with a table. You need to ensure that the data row associated with a specific pushpin on the map is highlighted when a user points the mouse to the pushpin. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Use the VEMap.onLoadMap event to specify a function call.
• B. Use the VEMap.onmouseover event to capture user interaction. Create a JavaScript function for highlighting the row in the table.
• C. Use the VEMap.onmousemove event to capture user interaction. Create a JavaScript function for highlighting the row in the table.
• D. Use the VEMap.AttachEvent method to attach a mouse event to the VEMap object that calls a function.

You create a Web page that contains a Virtual Earth 6.0 map. You want to track how your users are interacting with the map.
You need to track the following usage data.
number of Virtual Earth transactions
zoom usage
map styles that are being used
Which two methods or events should you use? (Each correct answer presents part of the solution. Choose two.)

• A. VEMap.ShowInfoBox
• B. scroll
• C. onchangeview
• D. VEMap.Find
• E. onmousemove

You are writing a code segment for a Virtual Earth 6.0 application. The code segment returns data for multiple locations to a client-side JavaScript function that makes the initial request.
The returned data contains the following properties for each location:
ID
Latitude
Longitude
Address
You need to format all locations and their properties in JavaScript Object Notation (JSON) format.
Which code segment should you use?

• A. var results = {
  0:{
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St "
  }
  };
• B. var results = {
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St ."
  };
• C. var results = new Array();
  results[0] = 123;
  results[1] = 40.0;
  results[2] = -74.0;
  results[3] = "123 Main St.";
• D. var results = new Array();
  results[0] = new Array();
  results[0][0] = 123;
  results[0][1] = 40.0;
  results[0][2] = -74.0;
  results[0][3]= " 123 Main St .";
