DRAG DROP - (Topic 1)
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.)

You are creating a Virtual Earth 6.0 application to be viewed by using Microsoft Internet
Explorer. The Web pages of the application contain maps.
The head section of the Web pages contains the following code fragment.
< script type="text/javascript">
var map = null;
function GetMap(){
map = new VEMap('Map');
map.LoadMap();
ResizeMap();
}
< /script>
< style type="text/css">
html, body{ overflow:hidden; }
< /style>
The body section of the Web pages contains the following code fragment.
< body onload="GetMap();">
< div id='Map' style="position:relative; width:400px;
height:400px;"></div>
< /body>
You need to resize the maps on the Web pages so that they exactly fit into the dimensions of the available browser area.
Which code segment should you use?

• A. function ResizeMap(){ var height = screen.height; var width = screen.width; map.Resize(width, height); }
• B. function ResizeMap(){ var height = document.body.offsetHeight; var width = document.body.offsetWidth; map.Resize(width, height); }
• C. function ResizeMap(){ document.getElementById('Map').style.width = "100%"; document.getElementById('Map').style.height = "100%"; }
• D. function ResizeMap(){ document.getElementById('Map').style.width =
  screen.availWidth; document.getElementById('Map').style.height = screen.availHeight; }

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

You are creating a Web application by using the Virtual Earth 6.0 map control. A Web page of the application loads two map controls named Map1 and Map2. Map1 displays a navigable, primary map. Map2 is the secondary instance of Map1 and displays an overview of the primary map. You need to ensure that when the user navigates the primary map, the overview is automatically updated. Which code segment should you use?

• A. Map1 = new VEMap('myMap'); Map1.LoadMap(); Map1.SetMapView(defView1);
  Map1.AttachEvent("onchangeview", UpdateOverview);
• B. Map2 = new VEMap('myMap'); Map2.LoadMap(); Map2.SetMapView(defView1);
  Map2.AttachEvent("onresize", UpdateOverview);
• C. Map2 = new VEMap('myMap'); Map2.LoadMap(); Map2.SetMapView(defView1);
  Map2.AttachEvent("onchangeview", UpdateOverview);
• D. Map1 = new VEMap('myMap'); Map1.LoadMap(); Map1.SetMapView(defView1);
  Map1.AttachEvent("onresize", UpdateOverview);

You deploy a Virtual Earth 6.0 application that uses Microsoft ASP.NET Asynchronous
JavaScript and XML (AJAX) implementation to retrieve data.
The myAjaxCallback function evaluates any AJAX response. The function contains the following code segment. (Line numbers are included for reference only.)
0 1 function myAjaxCallback (){
0 2 if (xmlHttp.readyState == 4){
0 3 ...
0 4 }
0 5 }
At the time the request was made, the server was overloaded. When the server processed the AJAX request, the server returned an error message.
You need to ensure that the application does not produce a fatal exception due to the error generated from the AJAX response.
Which code segment should you insert at line 03?

• A. try{ eval(xmlHttp.responseText); } catch(error){ if(xmlHttp.status == 200){ eval(xmlHttp.responseText); } }
• B. try{ eval(xmlHttp.responseText); } catch(error){ // Update user with status here. }
• C. If(xmlHttp.status == 200){ eval(xmlHttp.responseText); } else{ // Update user with status here. }
• D. try{ eval(xmlHttp.responseText); } catch(error){ eval(xmlHttp.responseXML); }
