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

1. You are creating an application that will display a Virtual Earth 6.0 map inside a pop-up window that will be viewed by using Microsoft Internet Explorer.
You write the following code segment.
0 1 var map = null;
0 2 function GetMap(){
0 3 map = new VEMap('Map');
0 4 map.LoadMap();
0 5 ...
0 6 }
You need to ensure that the following requirements are met:
The height of the map is half the height of the pop-up window.
The width of the map is one-third the width of the pop-up window.
Which code segment should you insert at line 05?

A) map.Resize(document.body.style.width/3, document.body.style.height/2);
B) document.getElementById('Map').style.width = document.body.style.width/3; document.getElementById('Map').style.height = document.body.style.height/2;
C) map.Resize(document.body.offsetWidth/3, document.body.offsetHeight/2);
D) document.getElementById('Map').style.width = document.body.offsetWidth/3; document.getElementById('Map').style.height = document.body.offsetHeight/2;

2. A Web site displays a Virtual Earth 6.0 map in two-dimensional mode. You need to display data legends on the Virtual Earth map by using a custom control. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Create an IFRAME element that has the same size and the same location as the custom control. Set the value of the frameborder property of the IFRAME element to 0 and the value of the scrolling property to no.
B) Loop through the Document Object Model (DOM) of your application. Insert the data legend as a child of the DIV element that contains the Virtual Earth map.
C) In the style property for the IFRAME element, set the value of the z-index attribute to 1 and the position settings to match those of your control. In the style property for your custom control, set the value of the z-index attribute to a number greater than 1.
D) Add the data legends to the HTML element. Call the VEMap.AddControl method.
E) Use the document.CreateElement method of the Document Object Model (DOM) to create a new HTML element.

3. DRAG DROP - (Topic 0)
A news channel wants to display live traffic incident information for a city on a Web site.
You develop a three-tier architecture. The Microsoft MapPoint Web Service delivers traffic information that is managed by a user-defined class. The class acts as a SOAP-AJAX connector, Users interact with a Virtual Earth 6.0 map that is already loaded.
You need to ensure that the traffic incident information is displayed on a new layer of the
Virtual Earth map as the map is navigated by the users.
Which sequence of actions should you perform? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)

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

5. Your companys Web site has a Virtual Earth 6.0 map. You create custom buttons. You need to ensure that Web site users are able to pan the map to the north-east direction.
What should you do?

A) Use VEMap.Pan with delta x > 0 and delta y > 0.
B) Use VEMap.Pan with delta x > 0 and delta y < 0.
C) Use VEMap.Pan with delta x < 0 and delta y > 0.
D) Use VEMap.Pan with delta x < 0 and delta y < 0.
