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

1. You are creating a Web application by using the Virtual Earth 6.0 map control. You need to identify the minimum browser software and versions that the application can support.
Which three browser configurations should you use? (Each correct answer presents part of the solution. Choose three.)

A) FireFox 0.9
B) FireFox 2.0
C) Microsoft Internet Explorer 6.0
D) Netscape Navigator 6.0
E) Safari 2
F) Microsoft Internet Explorer 5.0

2. You are creating a Web application by using the Virtual Earth 6.0 map control.
A Web page of the application loads a map of a predefined location by using the following code segment.
var map = null;
var defView1= new VEMapViewSpecification(new
VELatLong(40.689167,-74.04472), 16, 360, -45, 0);
function GetMap(){
map = new VEMap('myMap');
map.LoadMap(); map.SetMapView(defView1);
map.SetMapStyle('h')
map.SetMapMode(VEMapMode.Mode3D);
}
You need to display a zoomed out view of the main map in a separate control on the same
Web page.
Which code segment should you use?

A) map2= map.ShowMiniMap(50, 300); defView1=map.GetMapView(); var
zL=map.GetZoomLevel(); map2.LoadMap(); map2.SetMapView(defView1); zL=zL-6; map2.SetZoomLevel(zL);
B) map.ShowMiniMap(50, 300);
C) map2=new VEMap('myOverViewMap'); defView1=map.GetMapView(); var
zL=map.GetZoomLevel(); map2.LoadMap(); map2.SetMapView(defView1); zL=zL-6; map2.SetZoomLevel(zL);
D) map2=new VEMap('myOverViewMap'); defView1=map.GetMapView(); var
zL=map.GetZoomLevel(); map.ShowControl('myOverViewMap');
map2.SetMapView(defView1); zL=zL-6; map2.SetZoomLevel(zL);

3. 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("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"))
B) 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"))
C) 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
D) 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"))

4. DRAG DROP
The location data of your company branch offices is stored as description and title in pushpins on a Virtual Earth 6.0 map.
You need to ensure that the data is displayed in a data panel named BranchInfo on top of the map every time a user moves the mouse over the pushpin.
What should you do? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)

5. A construction company wants to display plots on a Virtual Earth 6.0 map. The photographs of the plots are stored as JPEG files. You instantiate a pushpin shape of the type VEShapeType.Pushpin. You need to set a custom icon to the pushpin. What should you do?

A) Set the shape icon by using the SetCustomIcon method.
B) Create a new pushpin shape object.
C) Set the pushpin icon by using the SetIconAnchor method.
D) Create a new shape layer object.
