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

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.)

Correct Answer:

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

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

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.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.
• B.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.
• C.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.
• D.Use the document.CreateElement method of the Document Object Model (DOM) to create a new HTML element.
• E.Add the data legends to the HTML element. Call the VEMap.AddControl method.
