Microsoft TS: Ms Virtual Earth 6.0, Application Development Sample Questions:

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

2. You are creating a North American reverse geocoding application by using the Microsoft
MapPoint Web Service. The application must convert the latitude and longitude coordinates of a point on the map into a string that contains the city, province/state, and country. You need to obtain the string in the following format: "city, province/state, country". Which code segment should you use?

A) Dim getInfoOptions As New GetInfoOptions() getInfoOptions.IncludeAddresses = True getInfoOptions.IncludeAllEntityTypes = True Dim locations As List(Of Location) = _ findService.GetLocationInfo(origin, "MapPoint.NA", getInfoOptions) Dim address As String
= locations(0).Entity.DisplayName
B) Dim getInfoOptions As New GetInfoOptions() getInfoOptions.IncludeAddresses = False getInfoOptions.IncludeAllEntityTypes = False getInfoOptions.EntityTypesToReturn = New
String() {"PopulatedPlace"} Dim locations As List(Of Location) = _
findService.GetLocationInfo(origin, "MapPoint.NA", getInfoOptions) Dim address As String
= locations(0).Entity.DisplayName
C) Dim getInfoOptions As New GetInfoOptions() getInfoOptions.IncludeAddresses = True getInfoOptions.IncludeAllEntityTypes = False getInfoOptions.EntityTypesToReturn = New
String() {"AdminDivision1"} Dim locations As List(Of Location) = _
findService.GetLocationInfo(origin, "MapPoint.NA", getInfoOptions) Dim address As String
= locations(0).Entity.DisplayName
D) Dim getInfoOptions As New GetInfoOptions() getInfoOptions.IncludeAddresses = True getInfoOptions.IncludeAllEntityTypes = False getInfoOptions.EntityTypesToReturn = New
String() {"PopulatedPlace"} Dim locations As List(Of Location) = _
findService.GetLocationInfo(origin, "MapPoint.NA", getInfoOptions) Dim address As String
= locations(0).Entity.DisplayName

3. The branch office locations of your company are saved and shared in a portal data store by using the Live Search Maps portal. The company wants to display the locations on a Virtual
Earth 6.0 map. You need to add the saved data as a new layer on the Virtual Earth map.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

A) Import the data as GeoRSS to a new layer.
B) Import the data as VECollection to a new layer.
C) Extract the GUID from a Live Search Maps Collection reference.
D) Access the data by using the URL for the Live Search Maps Collection object.

4. You are integrating third-party data into a Virtual Earth 6.0 application. The data that is retrieved from the third party is stored in an array named Results. The Results array is stored inside a Web handler. The data is stored in the following format.
Results(0).Add("name", "Mike Pizzaria") Results(0).Add("address", "123 Main St., New
York, NY") Results(0).Add("latitude", "40.123") Results(0).Add("longitude", "-70.456")
Results(0).Add("thumbnail", "http://www.site.com/st3465.jpg") ... Return Results The Web handler uses the GeoRSSFeed class to accept items of type GeoRSSItem. The class contains the ToString() method that writes the GeoRSS feed to a string. The Web handler
GeoRSS integration is defined by the following code segment. (Line numbers are included for reference only.) 01 Dim feed As New GeoRSSFeed() 02 Dim curItem As GeoRSSItem
03 For i As Integer = 0 To Results.Count - 1 04 curItem = New GeoRSSItem() 05 ... 06 feed.Add(curItem) 07 Next 08 // Write feed to HTTP Response 09
context.Write(feed.ToString()); The Web handler uses the GeoRSSItem class that contains the following code segment. (Line numbers are included for reference only.) 10
Public Class GeoRSSItem 11 Public elements As Dictionary(Of String, String) 12 Public
Sub New() 13 elements = New Dictionary(Of String, String)() 14 End Sub 15 Public Sub
Add(ByVal pName As String, _ ByVal pValue As String) 16 elements.Add(pName, pValue)
17 End Sub 18 Public Overloads Overrides Function ToString() As String 19 Dim returnValue As New StringBuilder() 20 For Each key As String In elements.Keys 21 returnValue.AppendFormat("" & Chr(9) & "" & _ Chr(9) & "<{0}>{1}</{0}>" & Chr(10) & "", _ key, elements(key)) 22 Next 23 Return returnValue.ToString() 24 End Function 25 End
Class You need to encode the data inside the Results array into the GeoRSS format.
Which code segment should you insert at line 05?

A) curItem.Add("name", Results(i)("name")) curItem.Add("address", string.Format("{0}|{1}",
_ Results(i)("address"), Results(i)("thumbnail")) curItem.Add("latitude",
Results(i)("latitude")) curItem.Add("longitude", Results(i)("longitude"))
B) curItem.Add("title", Results(i)("name")) curItem.Add("description", Results(i)("address")) curItem.Add("latitude", Results(i)("latitude")) curItem.Add("longitude",
Results(i)("longitude")) curItem.Add("icon", Results(i)("thumbnail"))
C) curItem.Add("title", Results(i)("name")) curItem.Add("description",
String.Format("{0}|{1}", _ Results(i)("address"), Results(i)("thumbnail"))) curItem.Add("latitude", Results(i)("latitude")) curItem.Add("longitude",
Results(i)("longitude"))
D) Dim objEnumerator As IEnumerator Dim Keys As Collections.Generic.Dictionary(Of
String, _ String).KeyCollection = Results(i).Keys() Dim curKey As String objEnumerator =
Keys.GetEnumerator() Do While objEnumerator.MoveNext curKey =
objEnumerator.Current curItem.Add(curKey, Results(i)(curKey)) Loop

5. You create a Microsoft MapPoint Web Service application that accepts routes from users.
You need to find points of interest that are within one mile of a route or within three miles of the endpoints of the route. What are two possible ways to achieve the goal? (Each correct answer presents a complete solution. Choose two.)

A) findNearRouteSpec.Distance = 1 findResults = findService.FindNearRoute ( findNearRouteSpec ) foundLocations.Add ( FindResults ) findNearbySpec.Distance = 3 For
Each findResult As FindResult In FindResults.Results findNearbySpec.LatLong = findResult.FoundLocation.LatLong FindResults = findService.FindNearby ( findNearbySpec
) foundLocations.Add ( FindResults ) Next
B) findNearRouteSpec.Distance = 1 findResults = findService.FindNearRoute ( findNearRouteSpec ) foundLocations.Add ( findResults ) findNearbySpec.Distance = 3 For
Each segment As Segment In route.Itinerary.Segments findNearbySpec.LatLong = segment.Waypoint.Location.LatLong findResults = findService.FindNearby ( findNearbySpec ) foundLocations.Add ( findResults ) Next
C) findNearRouteSpec.Distance = 1 findResults = findService.FindNearRoute ( findNearRouteSpec ) foundLocations.Add ( findResults ) findNearbySpec.Distance = 3 For
Each segment As Segment In route.Itinerary.Segments For Each direction As Direction In segment.Directions findNearbySpec.LatLong = direction.LatLong findResults = findService.FindNearby ( findNearbySpec ) foundLocations.Add ( findResults ) Next Next
D) findNearRouteSpec.Distance = 1 Dim findResults As FindResults = _
findService.FindNearRoute ( findNearRouteSpec ) foundLocations.Add ( FindResults ) findNearbySpec.Distance = 3 findNearbySpec.LatLong = startLatLong FindResults = findService.FindNearby ( findNearbySpec ) foundLocations.Add ( FindResults ) findNearbySpec.LatLong = endLatLong FindResults = findService.FindNearby ( findNearbySpec ) foundLocations.Add ( FindResults )
